Mechanical Specifications YORK Air-Cooled Condensers, Models VDC-113D60 through VDC-266C60, are available in 33 standard model sizes for air conditioning and refrigeration applications and may be used with any type of compressor for halocarbon refrigerants. Similar units are available for industrial fluid cooling. Contact Johnson Controls for special applications, and refer to Form 195.29-EG2 for additional information. Air-cooled condensers operate dry (requiring a minimum of maintenance) and do not require pump and water piping installation. Vertical airflow units are standard design for low silhouette applications. LEGS Made from heavy-gauge galvanized steel with foot pads and mounting holes on the bottom of each leg. COIL Seamless copper tubes are expanded into fullcollar aluminum fins. Fins have a corrugated surface to enhance heat transfer. Fin edges are rippled to work harden and stiffen material for resistance to mechanical damage. Return bends and headers are brazed with highly ductile silver-bearing copper alloy. Coil casings and tubesheets are manufactured from galvanized steel. The tubesheets include aluminum inserts to prevent wear at the juncture of the tubes and tubesheets. Prior to shipment, coils are strength and leak tested at design pressure, dehydrated, evacuated, pressurized with dry air or nitrogen, and sealed for shipment. Coils up to four fan lengths use 3/8 in. OD tubes. Fiveand six-fan length coils use 1/2 in. OD tubes. For R-22, R-134a, R-407C, R-404A, and R-507A condensing, the 1/2 in. OD tube coils have a 420 psig (29 barg) design pressure at 250 F (121 C) for up to a 140 F (60 C) condensing temperature. For R-410A, the 3/8 in. OD tube coils have a 650 psig (44.8 barg) design pressure at 250 F (121 C) for up to a 140 F (60 C) condensing temperature. HEADERS Heavy-wall copper tube headers are designed for low pressure loss and proper refrigerant distribution. Double-wide units feature completely separate headers for each system circuit so there is no danger of refrigerant leakage between circuits. Inlet and outlet connections are provided. Integral subcooling is available for condensers. HOUSING The unit structure is comprised of heavygauge galvanized steel panels coated with baked-on champagne-colored powder paint, which, when subjected to ASTM B117 1000 hour salt spray testing, yields a minimum ASTM 1654 rating of 6. These panels are assembled with high-tensile strength fasteners. Fan panels have smooth-radius outlet orifices to ensure high energy efficiency and low noise level. FAN GUARDS Heavy-gauge OSHA-accepted fan guard design uses corrosion-resistant, coated-steel wire. FANS High-efficiency, high-strength airfoil-profile blade fans are used for low noise and energy-efficient performance. MOTORS Totally-enclosed air-over motors have integral automatic thermal overload (ATO) protection and are inverter duty ready. They feature ball bearings that are double-sealed and permanently lubricated. The standard motor is 2.0 hp, 3-phase, 60 Hz, 200, 230, 460 or 575 volts. See page 18 MOTOR MOUNTS Heavy-gauge galvanized steel channels are used to mount motors. BASIC FACTORY WIRING (STANDARD) Motors are wired to contactors located in a UL-listed NEMA 4, weather-resistant enclosure, which includes a non-fused disconnect switch, motor fuses, contactors, and an integral 115 volt control transformer. Enclosure ships mounted. BASIC MOTOR CONTROL (STANDARD) -- Basic motor control is less optional fan cycling. JOHNSON CONTROLS 3

Accessories and Options SPECIAL COILS While standard aluminum fins are compatible with most environments, when a unit is subjected to an especially corrosive atmosphere, such as coastal air with a high concentration of salt, special fin treatment may be required. The following options are available for these applications. HOLLY GOLD COAT This gold-colored, corrosionresistant, polyester-polymer-coated aluminum fin passes 1000 hours of ASTM B117 salt spray testing. Available only with 3/8 in. OD tube coils. ELECTROFIN COAT ElectroFin Coat is applied to the completed coil, protecting the tubes, fins, headers, and galvanized steel casing with a coating that passes 5000 hours of ASTM B117 salt spray testing. Not included in shipped loose manifold kit. COPPER FINS Copper-finned coils are available for applications where the environment may cause galvanic corrosion of aluminum fins. Available only with 3/8 in. OD tube coils. SEALTITE CONDUIT All fan motor wiring enclosed in sealed conduit. MANIFOLD KIT Ties dual inlet and outlet connections together on double-wide units for a single field connection (shipped loose for field installation). Typically used with a single chiller circuit or fluid coolers. MOTOR CONTROL OPTIONS FAN CYCLING Fan Cycling Options have motors wired to contactors located in a UL-listed NEMA 4, weatherresistant enclosure, which includes a non-fused disconnect switch, motor fuses, contactors, and an integral 115 volt control transformer. See Tables 10 and 11, page 25, for fan-cycling control settings or contact Application Engineering for support. Enclosure ships mounted. If there is a concern about noise due to fan cycling, It is recommended that HEAD PRESSURE CONTROL (VFD READY) be used. DOUBLE-WIDE-UNIT FAN CYCLING Fan Cycling Options for Double-Wide Units are available with fans cycling in pairs or, for temperature-controlled and pressurecontrolled fan cycling, with individual fan-bank fan cycling so the VDC circuit can serve individual chiller circuits. FAN CYCLING OPTIONS HEAD PRESSURE CONTROL BY TEMPERATURE Motors are wired for temperature-controlled fan cycling. A temperature sensor, supplied with a clip for mounting in the condenser s air stream or a bulb well for installation in fluid cooler s leaving fluid piping, must be field installed. Fans next to the header are always running when unit is activated by run signal. Receivers are not required. The A350 controller and stage module are supplied with this option to control the fans. HEAD PRESSURE CONTROL BY PRESSURE Required when selecting a VDC for use as a remote condenser for a YCRL chiller. Motors are wired for pressure-controlled fan cycling. Included pressure transducer(s) must be field installed. Fans next to the header are always running when unit is activated by run signal. Receivers are not required. The P470 controller and stage module are supplied with this option to control the fans. HEAD PRESSURE CONTROL BY (MICROPRO- CESSOR-READY RELAY OUTPUT BOARD) Motors are wired for microprocessor relay output board-controlled fan cycling. The microprocessor controller is not included and must be field provided. It is recommended that fans next to the header are always running when unit is activated by run signal.

Selection Data YORK remote air-cooled condensers are rated by Total Heat of Rejection (THR) at the condenser (expressed in Btu/h), at sea level air density. Total Heat of Rejection is the sum of the net refrigeration at the evaporator (compressor capacity) plus the energy input into the refrigerant by the compressor (heat of compression). Due to variations in the heat of compression by compressor type and manufacturer, it is recommended that the heat of compression value is obtained from the compressor manufacturer. However, if this is not available the Total Heat of Rejection can be estimated by applying correction factors and information in the tables below to the evaporator load to determine the THR requirement. Please refer to the examples on the following page for the estimation procedure. The two formulas that will be used are: Two-stage open compressor applications: Two-stage suction-cooled hermetic compressor applications: THR = compressor capacity (BTUH) + (2545 x bhp) THR = compressor capacity (BTUH) + (3413 x kw) HEAT OF COMPRESSION FACTORS TABLE 1 OPEN COMPRESSORS EVAP TEMP ( F) CONDENSING TEMPERATURE ( F) 90 100 110 120 130 140 50 1.09 1.12 1.14 1.17 1.20 1.24 40 1.12 1.15 1.17 1.20 1.23 1.28 30 1.14 1.17 1.20 1.24 1.27 1.32 20 1.17 1.20 1.24 1.28 1.32 1.37 10 1.21 1.24 1.28 1.32 1.36 1.42 0 1.24 1.28 1.32 1.37 1.41 1.47-10 1.28 1.32 1.37 1.42 1.47-20 1.33 1.37 1.42 1.47-30 1.37 1.42 1.47 * Outside normal limits for single stage compressor applications.

Estimate Condenser THR (if THR is provided, skip to step 2) THR = Compressor Capacity * Heat of Compression Factor 1. From Table 2, opposite 40 F evaporator temperature and under 120 F condensing, select heat of compression factor 1.27. 2. Multiply compressor or evaporator capacity by factor: THR = 250,000 Btuh x 1.27 = 317,500 Btuh. Step 2. Correct THR for Elevation and Ambient Temperature THR (corrected to sea level) = THR Air Density Correction Factor 1. From Table 3, under 3000 ft. elevation and opposite (interpolated) 95 F air temp, select air density correction factor 0.856. 2. Divide THR (from step 1) by factor: THR (corrected) = 317,500 Btuh 0.856 = 370,911 Btuh (at sea level). Step 3. Correct for Subcooling THR (subcooling adjusted) = THR Subcooling Correction Factor 1. From table 4, select 0.94 factor under 10 F Subcooling column. 2. Divide THR (from step 2) by factor: THR (subcooling adjusted) = 370,911 Btuh 0.94 = 394,586 Btuh (adjusted for sea level and subcooling). Step 4. Select Condenser Condenser ratings are provided as Btuh- F TD, so required THR must be divided by TD to obtain basic unit rating at 1 F TD. 1. Divide required unit capacity by TD (25 F) to obtain basic unit rating at 1 F TD: 394,586 Btuh 25 F = 15,783 Btuh- F TD. 2. From Unit Ratings table under R-410A heat rejection, select model VDC-126D60 with a base capacity of 16,793 Btuh- F TD. Step 5. Calculate actual operating TD for unit selected Actual operating TD = THR (corrected) divided by basic unit capacity. 1. To determine TD at which unit will operate, divide THR (corrected) by base unit capacity: 394,586 Btuh 16,793 Btuh- F TD: TD = 23.5 F TD. JOHNSON CONTROLS 7

Selection Data - continued AIR-COOLED CONDENSERS FOR CHILLER APPLICATIONS YORK air-cooled condensers are available with matched liquid chillers for air conditioning or process applications. The following table lists scroll chillers cooling chilled water from 54 F to 44 F, using R-410A and condensing at 125 F saturated discharge temperature (SDT). They have been matched with an air-cooled condenser providing 10 F subcooled R-410A refrigerant to the chiller and operating under a 25 F TD (temperature difference between ambient and condensing temperatures). These ratings therefore represent a design ambient temperature of 100 F.

Application Data Loop Discharge Line Trap Condenser Discharge Line Condenser Compressor Liquid Line Receiver FIGURE 2* Trap Liquid Line PIPING DIAGRAMS The above piping diagram covers a common application where the air-cooled condenser is located on the same elevation as the compressor and receiver. The discharge line in this case is not too critical. The main problem usually associated with this arrangement is insufficient vertical height to allow free draining of the liquid refrigerant from the condenser coil to the receiver. To prevent gas binding in the receiver and liquid build-up in the condenser coil, locate the receiver as far below the condenser outlet as possible. Liquid lines must be free of any loops or traps and horizontal runs must be pitched toward the receiver. Compressor Receiver FIGURE 4* This diagram illustrates a typical piping arrangement where the remote air-cooled condenser is located on a higher elevation than the compressor or receiver. In this arrangement, the design of the discharge line is very critical and should be modified to the arrangement in diagram Fig. 2, unless a very constant and steady load is maintained. Loop Discharge Line A Condenser Discharge Line B Trap Liquid Line FIGURE 5* Compressor Receiver FIGURE 3* This piping diagram is recommended for applications of capacity controlled systems. Discharge line A is sized for the maximum load conditions. Discharge line B is sized for the minimum loading conditions at sufficient velocity to carry the oil to the condenser at the reduced capacity. This diagram illustrates another common application where two or more separate air-cooled condensers are interconnected to a single compressor. In this case, each condenser must have both equal capacity and equal pressure drop. The piping must also be so arranged as to insure equal lengths to and from each condenser. If unlike piping and/or unequal condensers are used, the unequal pressure drop will cause liquid to build up in one of the condensers, reducing its effective capacity. * Note: Receivers are shown in Figures 2 through 5 for convenience. Many applications do not require receivers when the volume of the refrigerant charge does not exceed 80% of the condenser coil internal volume and can be entirely stored in the condenser coil. 14 JOHNSON CONTROLS

Control Data VDC PRESSURE SETTING GUIDELINES When a YORK remote condenser type VDC is used with a YCRL chiller, the VDC must be ordered and installed with the Head Pressure Control High Pressure option which provides YORK model P470 pressure controllers factory mounted in the VDC control panel. Operating manuals for the P470 controllers are included in the VDC control panel to allow field setup of the fan staging. Johnson Controls recommends the following pressure set points for general use; if excessive fan cycling is noted the final stage of cycling should be adjusted (deadband increased). The dead band proposed in these guidelines is set to 125 psi, which is the standard setting for JCI air cooled R410 units (YLAA, YCAL). 2 stage units (2 fan single wide, 4 fan double wide VDC): Stage 1, ON when any compressor is ON Stage 2, ON at 380 psig, OFF at 255 psig 3 stage units (3 fan single wide, 6 fan double wide VDC): Stage 1, ON when any compressor is ON Stage 2, ON at 380 psig, OFF at 255psig Stage 3, ON at 405 psig, OFF at 280 psig 4 stage units (4 fan single wide, 8 fan double wide VDC): Stage 1, ON when any compressor is ON Stage 2, ON at 380 psig, OFF at 255 psig Stage 3, ON at 405 psig, OFF at 280 psig Stage 4, ON at 430 psig, OFF at 305 psig Compressor will unload when the discharge pressure reaches 565 psig. LOW AMBIENT OPERATION Since air-cooled condensers are often required to operate over a wide range of ambient air temperatures and variable loading conditions, provision must be made to maintain the overall system balance. Any air-cooled condenser tends to run at a low head pressure when operating in a low ambient air temperature. Low head pressures will result in poor expansion valve operation and this will in turn cause poor system operation due to the pressure imbalance. within certain limits, without adversely affecting the system operation. The capacity of an air-cooled condenser is directly proportional to the TD, which is the temperature difference between the air temperature entering the condenser and the condensing temperature. A condenser is usually selected to operate on a TD suitable for summer ambient air conditions. The capacity of the condenser is increased when operated at the lower ambient temperature which directly reduces the system head pressure. The lower limit of this varying head pressure is dependent upon the required pressure drop across the thermostatic expansion valve and, for normal air conditioning applications, should be maintained above that corresponding to a condensing temperature of 65 to 70 F. This, in effect, corresponds to an ambient air temperature lower limit of approximately 55 to 60 F. Air conditioning is usually not required at these ambient temperatures. However, to ensure sufficient receiver pressure during compressor start-up, it is recommended that a high-pressure cut-in switch be used to allow the head pressure to rise before the condenser fan starts. Many applications, such as commercial refrigeration, are such that operation is required below the above ranges (55 to 60 F). We offer three methods to maintain a desired condensing pressure: Fan cycling, flood-back valves, combination fan cycling and flood-back valves. LOW AMBIENT CONTROL OPTIONS FAN CYCLING CONTROL On multiple-fan units, individual fan sections can be cycled to not exceed nominal condenser capacity at low ambient conditions. Table 10 provides minimum ambient temperatures for effective fan cycle control. Lower ambient temperatures than listed are not recommended for this method of control. Table 11 gives temperature settings for all units referenced to various design temperature differences. In lieu of temperature control, fan cycling can be controlled by pressure controls using a factory provided pressure transducer inserted (by others) into condenser inlet piping. Specify the type of control when ordering this option. Air conditioning applications generally allow the operating head pressure to vary with the ambient air temperature 24 JOHNSON CONTROLS
