Energy Savings Evaporative Condenser Energy Savings Energy Savings Air cooled condensers can only reject heat to the ambient dry bulb as the condenser air passes over the condenser surface. Typical design dry bulb temperature is often considered to be 95 F. However, actual rooftop dry bulb conditions are usually much greater due to solar heat on a dark roof. See Figure 1. Evaporative condensers use a cooling spray of water that evaporates and cools the condenser air down toward the typical ambient wet bulb temperature of 75 F. SeeFigure 2. Evaporative condensers, therefore, reject heat to colder temperatures and operate at lower condensing temperatures. Therefore less compressor work and energy are required. This allows compressors in an evaporative condensing unit to operate at lower condensing temperatures and consume 25 40% less electricity than comparable air cooled units, especially at design conditions. Refer to Table 1. Figure 1: Air-Cooled Condenser Figure 2: Evaporative Condenser Table 1: Air-Cooled vs. Evaporative-Cooled Condensers Design Conditions ARI Design Conditions Ambient Temperature Condensing Unit kw per ton Condensing Temperatures Air Cooled 95 /75 F 1.15 1.20 125 135 F Evaporative Cooled 95/75 F 0.84 0.88 105 115 F Desert Design Conditions Air Cooled 110 /72 F 1.35 1.40 135 145 F Evaporative Cooled 110 /72 F 0.82 0.86 102 112 F Rooftops with Evaporative Condensers Save Money 1. Savings in Electrical Consumption Costs Both consumption and demand usually drive the electrical costs for large, non-residential customers. Electrical consumption is the total energy consumed and is usually measured in kw Hours. Several factors influence consumption, including unit efficiency, operating hours, and load profile. Daikin s Energy Analyzer computer program is the ideal tool for estimating energy consumption for a given building. 2. Savings in Electrical Demand Costs Electrical demand is the peak energy consumed in a billing cycle and is usually measured in kw. Demand costs associated with air-cooled and evaporative-cooled rooftops are relatively easy to compare. a. The 25 40% reduction in peak design condensing unit kw translates into a 25 40% savings in condensing unit demand costs. Based on utility rate structures, this can be a substantial savings. b. In addition, Daikin offers airfoil supply and return fans that reduce design bhp and air handler demand costs by up to 20%. 3. Savings in Installation Cost Rooftop ampacity and electrical service costs are proportional to design kw. A 25 40% reduction in condensing unit design kw translates into smaller and less expensive wires, disconnects and transformers that feed the rooftop units. Daikin s airfoil supply and return fans often save one or two motor sizes and further reduce the required electrical service. Typical Savings vs. Air-Cooled Rooftop Systems To illustrate the savings generated by evaporative condensing, consider a two-story shopping mall using several 125-ton VAV rooftop units and occupied 365 days a year. Assume external static pressures of 2.5" for each supply duct and 0.5" for return ducts. Table 2 through Table 4 show the Daikin RPE evaporative condenser rooftop if this mall is located in the Los Angeles, New York and Las Vegas.

To locate your Daikin representative, visit DaikinApplied.com or call (800) 432-1342. Figure 4: Energy Analyzer - Primary System Screen RPE Energy Costs are Competitive Using the 0.85 kw/ton condensing unit efficiency from the previous example, Figure 3 shows a comparison of a Daikin RPE evaporative condenser rooftop system with a 0.55 kw/ ton water-cooled chiller system. In this case, we assumed that the chiller system would have constant flow pumps and that it unloads to 0.46 kw/ton. As shown in Figure 3, the energy performance of the two systems is very comparable, with the RPE offering a significant part load advantage and the chiller offering a small full load advantage. Given that most air-conditioning systems operate at 60% load or less over the great majority of a typical year, the Daikin RPE may be the best energy savings investment. www.daikinapplied.com 7 CAT 219-2 ROOFPAK PACKAGED SYSTEMS

Factory Installed and Wired Options Optional Water Treatment All evaporative condensing products require water treatment systems for proper operation. The water treatment system serves the following purposes: Controls organic contamination Reduces condenser fouling and corrosion Reduces cleaning frequency and water usage Overview Daikin RPE/RDE units come with a spray system, pump, sump strainer, automatic float controlled intake, and manual blowdown as standard. Daikin evaporative condenser rooftop systems can provide as much as 44% in compressor energy savings compared to competitive air-cooled rooftop units. Until now, chemical water treatment was required to prevent scale build-up and microbial growth in the moisture laden condenser section of these units. Daikin now offers an alternative: a chemical-free water treatment system that can substantially lower the cost of water treatment, eliminate the use of hazardous chemicals and simplify the water treatment process. Figure 14: Water Treatment System Eliminates Chemical Costs This system eliminates the use of hazardous chemicals, including scale inhibitors, biocides and corrosion inhibitors. Typical yearly savings range from $1,800 to $2,700 per year for a 150 ton evaporative condenser rooftop unit. Minimizes Corrosion Daikin uses only stainless steel, copper and PVC in its evaporative condenser plumbing. Clean, chemical-free water, saturated with precipitates by this system, does not attack these materials. Blowdown and Water Consumption Controlled blowdown is required on Daikin RPE/RDE units as it should be with all evaporative condensing products. It involves draining off a portion of the highly concentrated water from the bottom of the sump and replacing it with lower concentration make-up water to prevent scale. Scale protection is required because the evaporation process leaves behind solids (scale) that will coat the heat exchanger surfaces and sump. This reduces the capacity, efficiency, and life expectancy of the equipment. Manual blowdown occurs whenever the spray pump operates and a manual valve adjusts flow. This inevitably bleeds off too much [increased water costs] or too little [risking scale build up] water. Controlled bleed off is included with the Daikin water treatment controller. The concentration of scale forming solids is measured by water conductivity and the control opens or closes a solenoid to allow the proper amount of bleed off. The conductivity set point should be adjusted based on water analysis to maintain a desired cycles of concentration. Theoretical water consumption required for proper heat rejection is 1.8 gallons per ton hour. All of this water evaporates and none goes into the sewer. An additional 0.6 to 0.9 gallons per ton hour is also required for make up and blowdown. The exact amount should be determined by water analysis. The RPE/RDE includes a float valve and solenoid that automatically refills the sump as required. Blowdown must be handled in accordance with local codes and normal procedures are as follows: Daikin non-chemical water treatment system - used blowdown water often can be drained to the storm sewer (check local codes) Field installed chemical water treatment system - used blowdown must not be drained to the storm sewer and is usually drained to the sanitary sewer (check local codes) Because most water utilities charge for both intake and sanitary sewer water flows based on intake meter readings, sanitary sewer charges may be reduced if sewer flow is proven to be less than water intake. Daikin offers both intake and blowdown water meters to document reduced sewer flow [confirm details with your local utility]. These meters are not included in the basic water treatment option. Reduces Water Consumption Costs With this system, supply water typically can be cycled through the evaporative system six times before it must be drained off to prevent scale. With chemical treatment systems, only three to four cycles are possible. This represents a water consumption savings of about 10%. CAT 219-2 ROOFPAK PACKAGED SYSTEMS 14 www.daikinapplied.com

Factory Installed and Wired Options A Cleaner Environment Daikin evaporative condenser rooftop units equipped with a chemical-free water treatment system contribute to a cleaner environment by reducing energy usage and by eliminating the introduction of hazardous chemicals into the waste stream. Reduces Sanitary Sewer Costs Savings in sanitary sewer costs can be even more dramatic. That s because this system requires no sanitary sewer usage all condenser water, including blow-down, usually can be drained to the storm sewer or used for irrigation (check local codes). This represents a 10 to 15% water cost savings if sewer flow is measured (i.e., credit is given for the water that evaporates during the cooling process) and even more if it is not. Chemical-Free Benefits As a scale inhibitor, the Daikin chemical-free system uses pulsed electromagnetic fields to neutralize the charge on particles suspended in water, causing them to attract to each other rather than to form scale on plumbing and heat transfer surfaces. The particles grow, encapsulate any microorganisms, and precipitate out of solution as a powder. A cyclone separator removes the powder from the system during the blow-down process. For microbial control, the system uses pulsed electromagnetic fields to attack the cell walls of any microorganisms that are not encapsulated. As a result, TBC is typically 75% less than with chemical treatment systems. In fact, total bacterial count (TBC) is so low that biofilms are normally prevented. Easy Maintenance The Daikin chemical-free water treatment system has no moving parts and is easy to maintain. Inspection and monitoring are only required once or twice per quarter, as follows: Check the water conductivity (and clean conductivity sensor if necessary) Check total bacteria count (TBC) Inspect general operation and controller settings LEED Point Available Chemical-free water treatment systems qualify for a LEED point under the Innovation heading, per a Credit Interpretation Request posted on the USGBC website. 12 to 18 Month Payback The superior performance of the Daikin chemical-free system costs a little more up front than a chemical feed system, tanks, and pumps. However, the water and chemical savings generally provide a 12 18 month payback, in addition to the financial benefit of cleaner water and heat transfer surfaces.

Application Considerations The RPE and RDE require many of the same application considerations as Daikin RPS and RDT units. More detail is provided in RPS Catalog 214 and RDT Catalog 217. For a copy of these catalogs, contact your local Daikin representative or visit DaikinApplied.com General Intended for normal HVAC use. Consult factory if cataloged operating range is exceeded, such as make up air. Compressor cooling below 45 F is not allowed Rig the unit in accordance with the instructions provided in the Installation Manual IM 791. Split units are available to reduce rigging weight and may be required if the total length exceeds 52 ft. For a copy of IM 791, contact your local Daikin representative or visit DaikinApplied.com Fire dampers may be required by code. They are not included Qualified Start-up of the unit in accordance with the IM 791 is required Clean off any road chemicals, such as winter salt, when the unit is received Proper water treatment must be provided before unit start-up Filters Application Considerations Filters should be replaced on a regular basis to avoid excessive pressure drop increases, especially on high efficiency cartridge filters Fan selection must consider dirty filter losses. Using a filter pressure drop midway between clean and dirty values is recommended unless maintaining minimum cfm is critical Daikin RPE units offer last in air stream final filters. They require special consideration The Daikin design uses full double-wall construction down stream of the final filters Cooling coils must be in the draw-through position. Final filters down stream of gas and electric heaters must be rated for 500 F temperatures. Maintenance personnel must use properly-rated replacement filters Location and Curb/Rail Support The structural engineer must verify that sufficient roof strength is provided Maximum unit pitch is 1/16 in. per foot. Curbs or supporting rails must be rigidly supported along the entire length of the unit to prevent deflection that results in door interference Gaskets must be installed between the curb and the unit, per IM 791 Curbs must be installed per NRCA guidelines See Roof Curbs on page 55 Avoid locating the unit near any heat source, exhaust, smoke stack, or any source of air-borne particles or chemicals Local codes must be followed regarding fastening the unit to the curb/rail and the curb/rail to the building. This is especially critical in higher risk, hurricane or seismic zones Refer to the Acoustics on page 18 to avoid noise and vibration problems Daikin curbs include supply and return opening support frames and perimeter channels that seal to the unit as it is placed on the curb. Therefore, duct connections can be made to the curb before the unit is placed www.daikinapplied.com 17 CAT 219-2 ROOFPAK PACKAGED SYSTEMS

Application Considerations Acoustics Ducted and radiated sound power ratings are available from your local Daikin sales representative. The designer is responsible for addressing these sound levels. The following guidelines will help to achieve the desired sound levels in the occupied space. Locate the unit as far away from sound sensitive areas as possible. Refer to the Location and Curb/Rail Support on page 17 Minimize supply and return fan TSP and select the fan as close to peak efficiency as possible. Avoid the do not select areas on the fan curve. Daikin offers several different fans per model size to allow for various design conditions. Refer to Fan Performance Data on page 44 Three different sound paths from the unit to occupants and/or neighbors must be considered: 1. Radiated path Use a concrete deck or pad when the unit must be located over sound sensitive areas. If this isn t possible, provide extra acoustical insulation under the condensing unit Only the supply and return ducts, and the essential plumbing and electrical connections should penetrate the acoustical insulation or roofing below the unit. The outside perimeter of the ducts must be sealed after they are installed If a built-up roof with metal decking is used, then the area inside the curb perimeter requires special attention: Provide an inverted 6" channel around the inside perimeter of the curb and seal to the curb Acoustical insulation must be installed above the decking and the 6" channel 2. Vibration path Locate the unit s center of gravity close to a main support beam to minimize roof deflection and vibration transmission into the building Daikin offers 2" deflection, supply and return fan spring isolation or rubber in shear isolators. The rubber in shear isolators should only be used when vibration isolation is clearly not required in the rooftop, such as when the unit is mounted on spring isolated curbs, spring isolated rails or the ground Daikin offers compressor spring isolation, including the necessary refrigerant line vibration eliminators Internal spring isolation options may be insufficient for some applications. Spring isolation of the entire unit may be required 3. Air-borne path through the supply and return openings Use 2003 ASHRAE Fundamentals Chapter 43 to help reduce ducted noise and minimize duct turbulence. Maintain straight ducts to and from the unit and avoid abrupt changes in duct size and direction. Avoid turns opposed to the fan wheel rotation. If 90 elbows are required, use turning vanes Use as much insulated return duct as possible and include at least one elbow and 15' of length. Maximum recommended velocities are 1000 1200 fpm Allow for duct break out and use oval or round duct whenever possible Insulate the first 20' of supply duct. The first 20' of rectangular duct should be routed over non-sensitive areas and avoid large aspect ratios. Maximum recommended velocities are 1800 2000 fpm Daikin offers factory-installed discharge plenums with optional perforated liners. The plenum provides several db of attenuation and discharges the air at a more uniform, relatively low velocity. Ducted supply noise can be further reduced by adding optional sound attenuators between the supply fan and the unit discharge Route the return air path through the length of the curb to add distance between the unit return opening and the building return opening CAT 219-2 ROOFPAK PACKAGED SYSTEMS 18 www.daikinapplied.com

Application Considerations Economizer, Return Fan and Exhaust Fan Application Rooftop economizer applications usually require return or exhaust fans to properly control building pressure and maintain minimum ventilation. Daikin offers both exhaust and return fan capability. They are not generally interchangeable for a given design. In general: Return air fans (RAF) should be used on ducted return systems (return ESP exceeds 0.4 0.5 in.) Properly selected propeller exhaust air fans (EAF) can successfully operate and save energy on open return systems (return ESP is less than 0.4 0.5 in.) Supply air fan (SAF) selection depends on whether a return or exhaust fan is used RAF system-saf handles only the supply ESP at design EAF system-saf handles both the supply and return ESP at design (EAF is OFF) Figure 16 illustrates why supply fan only units have problems, especially as return ESP increases. No exhaust will occur from the rooftop because the economizer section must be at a negative pressure The air balancer must adjust the outdoor air damper to generate large pressure drops at minimum ventilation settings (about 0.9" in Figure 16) Figure 17 illustrates how the addition of a return fan corrects these problems. The return fan is responsible for return system ESP and maintains a slightly positive pressure in the economizer section (about +0.1 in. in Figure 17) to allow for exhaust air control and a more suitable outside air intake pressure. Exhaust fans are very different than return fans and can not maintain proper building pressure and ventilation control as return ESP increases. The EAF is normally off during non-economizer operation. During these minimum outdoor air conditions, the system essentially acts like a supply fan only system When the exhaust fan cycles OFF, there is no device available to maintain a positive pressure for relief, the mixed air plenum pressure dramatically changes and minimum ventilation air control and space pressure control are lost An exhaust fan s performance weaknesses diminish as return ESP decreases. Properly selected and controlled propeller exhaust fans can successfully operate and save energy at reduced return ESP designs. At system operating conditions where a single fan can be used successfully, it generally will be more efficient than operating series fans under the same total load. When the exhaust fan turns off, the supply fan can more efficiently handle both the supply and return duct loads At the relatively high cfm, low static pressure conditions of exhaust/return application, exhaust fans can be selected closer to their peak design efficiency than can full return fans. This allows them to run more efficiently throughout their operating range. Therefore, when return duct losses don t dictate the use of a return air fan, exhaust fans are an efficient alternate.

Application Considerations Variable Air Volume (VAV) Daikin Rooftop VAV options include everything required to provide the full advantages of true shut-off VAV. Bypass VAV systems do not offer any fan energy savings at light load. Variable Frequency Drives for all indoor fans maximize part load fan efficiency and minimize fan sound generation Indoor fan volume control based on supply static pressure and building pressure Up to 2 supply duct sensors to properly respond to building diversity (such as east-west variation) Constant discharge temperature control. Shut-off VAV offers the following advantages Reduces first cost and energy due to building diversity Reduces indoor fan energy requirements at light load Provides the opportunity for efficient multiple zone control from a single unit and to match changing occupancy demands VFDs turn down in accordance with Figure 18 The benefits of Daikin airfoil fans are particularly applicable to VAV applications. Better efficiency and less noise at the medium static pressures associated with VAV Airfoil fans are much more forgiving than forward curved fans if unexpected variations in ESP occur They are non-overloading (bhp is fairly constant for a given RPM) and require less safety factor in motor selection They have steeper RPM lines (less variation in cfm for a given variation in ESP) Multiple forward curved fans are often used and they risk unstable fan paralleling at light load MicroTech III Control Supply fans are controlled to maintain constant supply duct static pressure. Run pressure-sensing tubes to the desired location (generally at the end of the main trunk) Use a second sensor when there is more than one main trunk, multiple floors, or significantly varying zones (such as east and west sides of a building) Return/exhaust fans are controlled to maintain building pressure in one of two ways. Daikin s exclusive Vanetrol supply/return fan tracking is generally preferred. Vanetrol is adjusted at system air balance to maintain proper building pressure throughout the expected loading conditions. This reduces the effect of wind, climate variation and doors opening and closing Direct building sensing control is available for exhaust fans or any return fan application that cannot predictably track the supply fan Daikin generally offers more steps of compressor capacity control than the industry norm, as well as HGBP, and these capabilities should be included on VAV applications to minimize variations in duct temperature. Figure 18: VFD Turndown CAT 219-2 ROOFPAK PACKAGED SYSTEMS 20 www.daikinapplied.com

Application Considerations Unit Operating Range Fan Operating Range The acceptable system operating range of the Daikin rooftop unit is determined by all of the following characteristics. Each of these limiting factors must be considered for proper performance and component design life. 1. Unstable fan operation 2. Maximum fan rpm 3. Maximum cabinet static pressure 4. Maximum face velocity (cooling coil is most important) 5. Minimum furnace or electric heater velocity 6. Turndown capability on VAV applications 7. Compressor operating pressures Figure 19 illustrates these limiting factors with the exception of items 6 and 7 above. The shaded area indicates the design operating range of the fan. For optimal efficiency, select fans as close to the fan s peak static efficiency line as possible. This line is the first system curve to the right of the unstable line illustrated. VAV fan selections must also allow for keeping the fan away from the do not select area at minimum design cfm. Cooling coil maximum face velocity is based on moisture blow off limitations and laboratory testing. 650 feet per minute maximum face velocity for 8 and 10 fin per inch coils. 600 feet per minute maximum face velocity for 12 fin per inch coils. Cooling coil minimum face velocity is 200 feet per minute for any coil selection. VAV systems must be designed such that this velocity is maintained at minimum airflow. Maximum design ambient wet bulb temperature varies per unit, but is at least 85 F. Evaporative condenser units are an excellent choice for high ambient applications. The minimum ambient temperature for compressor operation is 45 F. The MicroTech III Controller is set to prevent compressor operation below that temperature and use the economizer only when cooling is required at a lower ambient.

Application Considerations Indoor Fan and Motor Heat, Blow-Through vs. Draw-Through Cooling Indoor Fan and Motor Heat The indoor fan and motor electrical consumption is a sensible cooling load approximately equal to 2.8 MBh per bhp (depending slightly on motor efficiency). This occurs at the fan. See Figure 20 and Figure 21. The fan and motor preheat the mixed air before it enters a blowthrough cooling coil. The fan and motor reheat the air leaving a draw-through cooling coil. Refer also to 2001 ASHRAE Fundamentals Handbook, Chapter 31 Figure 20: Blow-Through vs. Draw-Through Concept Fan and motor temperature rise is equal to Btuh / (1.08 cfm) and is typically about 3 F Due to fan and motor heat placement (Figure 20), blowthrough coils provide a high sensible heat ratio while draw-through coils provide more latent cooling per total ton. Blow-through coils achieve a higher sensible heat ratio because they operate with a higher coil approach temperature and a lower entering relative humidity. Conversely, draw-through coils cool air at a lower approach temperature and a higher relative humidity, increasing latent cooling Blow-through coils effectively provide colder supply air temperatures per ton of air conditioning and greater sensible heat ratio. This potentially allows a significant reduction in design cfm for buildings with high sensible heat ratios and a resulting reduction in building energy use Figure 21: Blow-Through and Draw-Through Performance Comparison MAT 3 B.T.

Application Considerations Recommended Clearances Service Clearance Allow the recommended service clearances shown in Figure 22. Provide a roof walkway along two sides of the unit for service and access to most controls. Cooling Coil, Heat, and Supply Fan Service Clearance An additional clearance of 24" is recommended adjacent to the cooling coil, heat, and supply fan sections. Outdoor Air Intakes Do not locate outside air intakes near exhaust vents or other sources of contaminated air. If the unit is installed where windy conditions are common, install wind screens around the unit, maintaining the clearances specified. This is particularly important to prevent blowing snow from entering outside air intakes. Overhead Clearance 1. Unit(s) surrounded by screens or solid walls must have no overhead obstructions over any part of the unit. 2. The area above the condenser must be unobstructed in all installations to allow vertical air discharge. 3. The following restrictions must be observed for overhead obstructions above the air handler section: a. There must be no overhead obstructions above the furnace flue or within 9 inches of the flue box. b. Any overhead obstruction shall not be within 2 inches of the top of the unit. c. A service canopy must not protrude more than 24 inches beyond the unit in the area of the outside air and exhaust dampers. d. Flue box outlet must extend above any obstructions.

Application Considerations Ventilation Clearance Unit(s) surrounded by a screen or a 50% open area fence: 1. The bottom of the screen should be a minimum of 1 ft. above the roof surface. 2. Minimum distance from the unit to screen is the same as the recommended service clearance. 3. Minimum distance, unit-to-unit = 120 in. Figure 23: Ventilation Clearances Unit(s) surrounded by solid walls: 1. Minimum distance from the unit to the wall is 96 inches for all sizes. 2. Minimum distance from the unit to another unit is 120 inches. 3. Wall height restrictions: a. No restrictions if there is a wall on one side only, or on two adjacent sides. b. The wall height is restricted to no more than the unit height with walls on more than two adjacent sides.

Application Considerations Control and Power Wiring Wiring must be done in accordance with the NEC and local code. For wire sizing instructions, see Supply Power Wiring on page 60. All units require 208-60-3, 230-60-3, 460-60-3, 575-60-3 or 380-50-3 power. Size wire in accordance with tables 310-16 or 310-19 of the National Electric Code. Wires should be sized for a maximum 3% voltage drop. Copper conductors must be used. Actual voltage at the unit connection must be within +/- 10% of nameplate voltage at all times. Daikin offers several power connection options. Single power connection with a terminal block or nonfused disconnect are normally the most economical. Systems served by emergency generators often require two power connections (with terminal blocks or non-fused disconnects). The generator normally serves only the air handler and controls portion so the condensing unit must be powered separately. Each unit is provided with a separate 115 volt convenience outlet that requires a separate power connection per the NEC. A second, 115 volt power supply is required to power the optional unit heater for the service compartment. Most units require a zone temperature sensor for night heat and other functions. The sensor must be properly placed so that its temperature reflects the zone requirements. Avoid outside walls, sunlight and close proximity to supply air or heat generating equipment. A return air sensor can be substituted for the space sensor if necessary. Altitude Adjustments Fan curve performance is based on 70 F air temperature and sea level elevation. Selections at any other conditions require the following adjustment for air densities listed in Table 7. Higher elevations generally require more RPM to provide a given static pressure but less bhp due to the decrease in air density. 1. Assume 32,000 cfm is required at 3.11" TSP. The elevation is 5000 ft. and 70 F average air temperature is selected. A 40" DWDI airfoil fan is selected. 2. The density adjustment factor for 5000 ft. and 70 F is 0.83. 3. TSP must be adjusted as follows; 3.11" / 0.83 = 3.75" 4. Locate 32,000 cfm and 3.75 on the fan curve. RPM = 900 and bhp = 27.5. The required fan speed is 900 RPM. 5. The consumed fan power at design = 27.5 bhp 0.83 = 22.8 bhp. Figure 24: RPE 105C - 135C 40 in.

Application Considerations Furnace Performance Gas heat performance data is based on standard 70 F combustion air temperature and zero feet altitude (sea level). Furnace altitude derate may be 4% per 1000 feet above 2000 feet due to lesser combustion air density. However, if design ambient is cold enough, then the combined affect of colder temperature and altitude may have an offsetting impact on combustion air density. Example: A 1000 MBh furnace at 70 F ambient and at an altitude of 5000 feet is derated (0.04 3 = 0.12). At 1000 MBh input (1000 0.12 MBh), the actual input is (1000 120 = 880 MBh) at 5000 feet. Above 6000 feet, consult factory. Freezing Concerns Freeze protection measures must be taken for any rooftop exposed to freezing conditions. The owner and building designer must take primary responsibility based on the exact climate and installation conditions. Drain all condenser water as soon as the climate allows the economizer to provide all required cooling. The optional sump heater is recommended to protect the sump if ambient temperatures can drop to freezing conditions (even at night). Spray System The spray tree and nozzles are not vulnerable to freezing because water drains out of them when the spray pump is OFF. Remove the sump drain plug whenever the unit is not in operation to prevent precipitation from building up in the sump and drain. Two freeze protection options are required to prevent the rest of the spray system from freezing. 1. An optional service vestibule heater provides primary freeze protection of the spray system enclosed in the vestibule. A thermostat turns the unit heater on when vestibule temperature drops to 40 F. 2. A sump heater is a recommended option that includes the following: An ambient thermostat-controlled insertion heater for the sump. Heat tape, insulation and thermostat for the sump drain. Heat tape, thermostat and insulation is included on the high pressure, factory water inlet piping upstream of the float control valve. An additional 10 feet of heat tape is provided to protect field connections. The installer must provide additional heat tape as required and insulate all field piping. An emergency drain solenoid opens up whenever the sump temperature drops near freezing and the spray system drains onto the roof. Hot Water and Steam Coils The RPE/RDE economizer offers better mixing capability than competitive rooftops but it cannot protect a hydronic coil from localized freezing. Optional air mixers are available to reduce air stratification and freezing concerns. Glycol is strongly recommended for hot water coils. It is the only reliable protection in the event of a power failure. Glycol s impact on coil and pump performance must be considered. An optional, non-averaging coil freezestat is offered on the downstream face of the heating coil. The outdoor dampers are shut, the fan is shut off, and the heating valve is fully opened, if freezing temperatures are experienced. The freezestat must be set somewhat above freezing temperatures to improve protection and may experience nuisance trips. It can not protect the coils during a power outage. Freeze protection strategies must not cause the cabinet temperature to exceed 150 F or motors and electrical equipment may be damaged. The field installed supply and bleed off water lines can enter the unit through the floor, inside the curb perimeter. This may provide sufficient protection depending on the temperature inside the curb. Use freeze protection if there is any concern the temperature inside the curb may fall below freezing. If no curb is provided, or field water piping enters the side of the unit, then additional measures are required such as heat tape and proper pipe insulation. Hot water and steam coil piping can enter the floor of the unit in the heat section and requires similar consideration. Water Treatment All evaporative condensers require proper water treatment. See Optional Water Treatment on page 14. The purpose of the water treatment system is to: Control organic contamination. Reduce condenser and sump scaling, fouling and corrosion. Reduce the required cleaning frequency. Proper water treatment involves two mandatory components (treatment and bleed off) and may also require a solid separator system depending on water quality. CAT 219-2 ROOFPAK PACKAGED SYSTEMS 26 www.daikinapplied.com

Application Considerations Condenser Water Connections Supply and return condenser water piping, plus field connections for chemical water treatment, are shown in Figure 25. Supply water can enter the floor of the service vestibule. Space is allowed in the vestibule for chemical tanks. Condenser bleed off (or return) connections allow easy drainage to a sanitary sewer through the floor of the vestibule. The spray operation washes particles out of the condenser air and condenser heat rejection evaporates water. This process leaves behind minerals and particles that were contained in the water. Water bleed off and water treatment are required to prevent the build up of scale, sludge and micro-organisms on the tube bundles and in the sump. These must be installed prior to unit start-up. See Optional Water Treatment on page 14. The theoretical water consumption required for proper heat rejection is 1.8 gallons per cooling ton hour. A nominal 100- ton unit, running at 50% capacity or 50 tons, evaporates 90 gallons of water per hour while rejecting condenser heat. Additional water must be added to the sump and bled off to the sanitary sewer to remove particles and minerals that accumulate in the water during operation. The required amount of bleed off varies with the water quality and is generally 0.6 to 0.9 gallons per ton hour or 33-50% of the theoretical evaporation water. Bleed off can be controlled in two ways. The RPE/RDE is provided with a manual shut off valve that can be used to adjust for a constant flow rate of bleed off water. This standard bleed off system can easily bleed off too much or too little water. Controlling bleed off with a solenoid valve, based on water conductivity or some other measure of particle concentration should be used. It is included in the RPE/ RDE water treatment option. The RPE sump also has a float control that automatically opens the supply water solenoid and replaces water lost in evaporation and bleed off. Water utility costs are usually based on the combination of water usage and sewer discharge. Only the bleed off portion of the water used by an evaporative condenser drains to the sewer (about 25-33% of total water used). Therefore, the sewer component of the cost of water may be reduced significantly if approved water meters are installed in the intake and bleed lines. The difference in meter rates reflects evaporation (water that will not go to the sewer) and this can be applied as a credit to the total water bill. Consult your local water utility for details.

Application Considerations Selection Instructions Building design and unit selection must allow for code compliance and installation limitations. The Daikin Rooftop unit offers excellent flexibility to meet diverse application requirements. This catalog includes summary performance tables at several operating conditions. Performance at other conditions can be estimated by interpolation but accuracy may suffer. Extrapolation often results in unreliable or damaging operating conditions and should not be used without factory guidance that is available through your local sales representative. Contact your Daikin representative for custom selections at specific design conditions. Selection Example Selection based on design criteria: 38,000 supply cfm at 2.00" ESP 36,000 return cfm at 0.75" ESP Sea level location using 60 Hertz power 95/75 F cooling ambient temperature 80/67 F cooling mixed air temperature [MAT] Total cooling loads requirements: 115 total tons 87 sensible tons Total sensible loads allow for: 50 hp SAF motor 25 hp RAF motor Gas furnace requirements: 1520 MBh of design heating 9" gas pressure available at the unit Furnace to only be used at design cfm for morning warm up and night heat An RPE unit must be used since a furnace, or electric heat, or final filters are required. Unit includes: Economizer plus return fan 65% filters plus pre-filters Cooling Selection Gross and net cooling The tables within the section Cooling Capacity Data on page 32 provide gross cooling or DX coil capacity based on DX coil entering air temperature (EAT). Net unit cooling capacity = [Gross cooling capacity] - [fan/motor heat] Fan/motor heat is critical. Refer to Indoor Fan and Motor Heat, Blow-Through vs. Draw-Through Cooling on page 22. Fan/motor heat = 2800 Btuh per bhp Fan/motor temperature rise (TR) = Btuh / (1.08 cfm) Mixed air vs. entering air temperature [MAT vs. EAT] Draw-through coil EAT = MAT Blow-through coil EAT = MAT + TR Blow-through EDB = mixed air EDB + TR Use a psychometric chart to find blow-through EWB. Selection From Capacity Tables Blow-through vs. draw-through. Refer to Indoor Fan and Motor Heat, Blow-Through vs. Draw-Through Cooling on page 22. Required sensible heat ratio < 80% [87 / 115 = 76%] An RPE is required due to the gas heat requirement. Therefore a draw-through RPE will be considered first. The RPE unit is available with both a low and high airflow DX coil. Refer to Table 8: Physical Data, RPE/RDE 076C - 150C on page 31. First select a high and low airflow coil with sufficient capacity. The RPE 110 with high airflow coil has sufficient capacity. No low airflow coil has sufficient capacity. Check coil velocity on all possible selections. High airflow face area = 76.0 square feet face velocity = 526 feet per minute. Low airflow face area = 60.8 square feet face velocity = 658 feet per minute The low airflow velocity is too much per Unit Operating Range on page 21. The RPE 110 [with high airflow coil] is sufficient per Table 16 on page 35. RPE 110 provides 117.6 total tons. RPE 110 provides 90.8 tons of sensible capacity. RPE 110 power consumption. 90.0 compressor kw (see Table 16 on page 35). 4.0 condenser fan and pump kw (see Table 20 on page 37). RPE 110 fan and motor heat must still be verified to be less than 50 = 25 bhp [per fan selection ] to be sure that net cooling capacity is sufficient.

Application Considerations Heat Selection See Catalog 214 or 217 for hot water, steam and electric heat selection instructions. Furnace Selection See Table 24 on page 40 and Table 25 and Table 26 on page 41. Table 24 and Table 25 indicate all of the furnace output capacities available. Output capacity is the true measure of furnace capacity Output capacity = Input capacity furnace efficiency Furnace efficiency = 80% for Daikin furnaces [similar to most direct fired furnaces] Net unit heating capacity = Furnace heating capacity + fan/motor heat = Furnace heating capacity + (50 + 25) 2800 = Furnace heating capacity + 210,000 Btuh Net heating capacity must satisfy the heating load of 1520 MBh. A 1400 MBh furnace is the correct choice. 1,400,000 Btuh + 210,000 Btuh exceeds the 1,520 MBh requirement. Assuming actual bhp exceeds (1,520,000-1,400,000) / 2800 = 42.9 bhp Baffle selection is based on design airflow and Table 22 on page 38. Baffle A has the greatest air pressure drop. Use baffle A from 21,000 to 37,999 cfm. Baffle B has the next greatest air pressure drop. Use baffle B from 38,000 to 38,999 cfm. Furnace air pressure drop at design air flow Refer to Table 24 for a 1400 MBh furnace with B baffle. 0.86" = furnace air pressure drop. Minimum inlet gas pressure Refer to Table 25 for a 1400 MBh furnace. Minimum inlet gas pressure = 8.8" for the standard modulating burner. 5.0" for the 20:1 high turndown, modulating burner. Furnace air temperature rise = Output Btuh 1,400,000 / 1.08 cfm = 32.4 F Filter Selection Refer to Table 8: Physical Data, RPE/RDE 076C - 150C on page 31 and Table 29: Component Pressure Drops on page 43. Table 8 shows the filter face area options. Table 29 shows performance data for each filter option: Clean filter air pressure drop Maximum airflow Selection for 65% filter at 38,000 cfm per Table 29. The medium airflow option is required Clean air pressure drop = 0.65" 30% prefilter clean air pressure drop = 0.36" Maximum recommended, dirty filter pressure drop [PD] for these filters: 0.7" for the 30% prefilter 1.0" for the 65% filters Please note that 95% filters are not part of this selection. 95% filter, maximum recommended, dirty PD = 1.20". Average filter PD = (0.7 + 1.0 + 0.65 + 0.36) / 2 = 1.35" Daikin generally recommends selecting the supply fan based on average filter PD. This allows airflow to best match specifications. Adjustments can be made to maintain critical, minimum airflow. www.daikinapplied.com 29 CAT 219-2 ROOFPAK PACKAGED SYSTEMS

Application Considerations Fan Selection Refer to the following: Table 8: Physical Data, RPE/RDE 076C - 150C on page 31 and Table 29: Component Pressure Drops on page 43. Fan Operating Range on page 21. Fan Performance Data on page 44. Return Air Fan and Exhaust Air Fan Selection Refer to Return Fans & Exhaust Fans on page 44 for 36,000 cfm at 0.75" ESP. The 44" SWSI return fan performance requires 19.5 bhp at 810 RPM. 19.5 bhp satisfies the RAF bhp specification. Supply Fan Selection The unit is specified to have a return fan. Therefore the supply fan must only handle internal APD and supply duct ESP. See Economizer, Return Fan and Exhaust Fan Application on page 19. Internal APD per Table 28 on page 42 and Table 29 on page 43. Economizer with return fan = 0.52" High airflow, 12 fpi, DX coil air pressure drop = 0.80" Gas furnace = 0.86" Average filter air PD = 1.35" TSP = 0.52 + 0.80 + 0.86 + 1.35 + 2.00 ESP = 5.54" SWSI Plenum vs. DWDI Supply Fan Selection Each type should be considered based on maximum efficiency and customer preference. DWDI fans are available on RPE, blow-through or draw-through units and must be used due to the furnace requirement. SWSI fans are only available on RDE, draw-though units. No blow-through coils or filters No furnaces or electric heat They offer advantages with side discharge Pick the optimum SAF for 38,000 cfm and 5.54" TSP 40" DWDI = 47.8 bhp and 1085 RPM (Figure 37 on page 46) 36" DWDI = 50.1 bhp and 1288 RPM (Figure 36 on page 46) 33" DWDI = do not select The 40" fan is superior. 5% more efficient and, therefore, quieter Saves a motor size Meets the 50 hp supply fan allowance We can now verify acceptable net heating and cooling capacities. Actual supply and return fan bhp = 47.8 + 19.5 = 67.3 Acceptable for cooling (67.3 < 50 + 25) Acceptable for heating (67.3 > 42.9) CAT 219-2 ROOFPAK PACKAGED SYSTEMS 30 www.daikinapplied.com

Heating Capacity Data Electric Heat Minimum cfm must satisfy two issues: 1. Maximum temperature rise is 60 F, therefore (minimum cfm = (MBh) (1000) / (1.085) (60). 2. Airflow must not be less than 22,000 cfm regardless of temperature rise.

W.C.) on page 41 1. Pressure drop through hood and damper is based on 30% of listed airflow. 2. Pressure drop through the economizer assumes that the majority of air will be passing through the return air dampers. If large quantities of outside air are required, pressure drops will increase causing airflow to decrease. 3. A diffuser is provided on units with blow-through cooling coils, final filters or hydronic heating.
