Overview The modular, Floor Mount computer room air-conditioning system offers efficient, effective and economical cooling for a variety of spaces. Precision environmental requirements now reach far beyond the confines of the traditional data center or computer room to encompass a larger suite of applications, referred to as technology rooms. Critical environment applications include: Computer rooms Telecommunication facilities Clean rooms Power equipment Medical equipment rooms Archives LAN/WAN environments A worldwide network of APC representatives is fully qualified to provide engineering, sales, installation and service for our products. APC warrants all parts for 12 months from shipment. Extended warranties are available. Capacity The Network AIR IR chilled water configuration is available in nominal 40kW and 80kW capacities. Room Air Distribution In-row systems are placed in line with rack enclosures. At least one system is used per hot aisle. Air is drawn in through the rear of the system, cooled, and discharged into the cold aisle using a top plenum. Optional diffusers can be installed on the left and right side of the plenum, over adjacent racks, to reduce noise levels and promote even air distribution. The NetworkAIR IR delivers high volumes of airflow (550 cfm per ton/160 cfm/kw) to eliminate hot spots in densely populated environments.

Scalable Solution for Critical Environments Temperature and Humidity Design Conditions Maintenance of temperature and humidity design conditions is critical to the smooth operation of a technology room. Design conditions should be 72-75 F (22.2-24.8 C) and 45-50% relative humidity (R.H.). As damaging as the wrong maintained conditions can be, rapid temperature swings can also have a negative effect on hardware operation. This is one of the reasons hardware is left powered up, even when not processing data. Computer room air conditioning is designed to maintain temperature at ±1 F and humidity at ±3-5% R.H. 24 hours a day, 8760 hours a year. Vapor barriers and sealed rooms are required to maintain these tolerances. In contrast, comfort systems are designed to maintain ±5 F from the temperature setpoint. There is usually no dedicated humidity control and the simple controllers cannot maintain the set point tolerance required for temperature, allowing potentially harmful temperature and humidity swings to occur. This is not acceptable for sensitive electronic equipment. Air Quality Computer room air conditioners provide a high CFM, around 600 CFM/ton (160 cfm/kw). This high CFM moves more air through the space improving air distribution and reducing the chance of localized hot spots. It also allows more air to move through filters, ensuring a cleaner environment. This requires a moderate- to high-efficiency filter bank to minimize airborne particles. Problems Caused by the Wrong Environment A poorly maintained technology room environment will have a negative impact on computer room operations. The results can range from data corruption to complete system shutdowns and failures. High & Low Temperature A high or low temperature swing or rapid temperature swings can corrupt data processing and shut down an entire system. Temperature variations can alter the electrical and physical characteristics of electronic chips and other board components, causing faulty operation or failure. These problems may be transient or may last for days. Transient problems can be very difficult to diagnose and repair. High Humidity High humidity can result in tape and surface deterioration, head crashes, condensation, corrosion, paper handling problems and (gold and silver) migration leading to component and board failure. Low Humidity Low humidity greatly increases the possibility of static electric discharges. Such static discharges can corrupt data and damage hardware. APC NetworkAIR IR, The Right Solution The APC NetworkAIR IR provides the maximum amount of computer room cooling in a compact footprint. Highly scalable, the system is capable of growing with your cooling needs as they increase. Each system comes standard with concise capacity controls for high efficiency operation. Compact Footprint The NetworkAIR IR delivers a high capacity of cooling in a small overall footprint. Since the system requires only front service access, systems can be placed side by side and valuable floor space is not wasted. 2 APC NetworkAIR IR

Scalable Solution for Critical Environments Chilled Water Configuration Chilled water systems utilize water from a chiller plant for cooling. chilled water is commonly used in large buildings and high rises and can serve multiple indoor units. System used with a chiller plant Cost effective for large installations EVAPORATOR CIRCUIT SETTER CHILLER In-row Advantages The In-row solution improves energy efficiency and cooling ability in a number of ways. First, the IR draws air directly from the hot aisle, allowing the IR to take advantage of higher heat transfer efficiency due to higher temperature differences. It can then discharge room temperature air directly in front of the servers it is cooling. This increases energy efficiency by allowing the chiller to operate at higher leaving water temperatures. Also, since it never chills the air below it's dewpoint, very little if any dehumidification occurs, significantly decreasing water consumption and energy use, and eliminating heat transfer inefficiencies caused by wet coils. APC NetworkAIR IR 3

Scalable Solution for Critical Environments Hot Aisle Containment System Extremely high density applications can further benefit from the In-Row cooling architecture of the NetworkAIR IR. Modular ceiling tiles and doors can be used to enclose the hot aisle. This increases the densities that can be handled in a single rack enclosure by eliminating mixing of hot and cold air streams. This method, called load neutralization, removes the heat from the hot aisle, cools it, and then returns it to the surrounding room area at room temperature or slightly below. The warmer return air temperatures that are achieved in this application increase the capacity of the air conditioner and almost eliminate the need for make-up humidification. Use of modular ceiling tiles across a 4 hot aisle that connects two opposite rack enclosures makes expansion quick and simple. Expansion kits, with necessary ceiling tile and all baying hardware, can be ordered to increase the size of the hot aisle by one rack on each side. The end doors can be easily removed and re-attached for expansion. The enclosed hot aisle prevents any warm return air from mixing with cold supply air. In effect, all surrounding room air can act as supply air to the system. The hot aisle containment system is beneficial in any environment. It can be deployed quickly in any controlled space without expensive additions to the infrastructure, such as raised floor or ductwork. na0905a 4 APC NetworkAIR IR

Standard Features Double Skin Panels The frame is bolt together 12 gauge formed steel for maximum strength. Cabinet is serviceable from the front. All exterior panels and corner posts on the frame are powder coated for durability and an attractive finish. Front exterior panel crowne is 16 gauge. All other panels are double skin, 22 gauge exterior, 22 gauge interior with 1 ½ lb. (.68 kg) per cubic foot insulated for quiet operation. Insulation is CFC-free and recyclable. Double skin panels isolate insulation from the air stream and further reduce sound levels. Left and right front panels are hinged and removable for easy access. Middle panel is removable. Direct Drive Motor/Blower Assembly Each cabinet includes precision balanced centrifugal blower assemblies that are less than 1 mil displacement on all axis for quiet, reliable operation. The blowers are mounted based on mass and frequency to eliminate vibration and noise. A direct drive (L 10-500,000 hour bearing life) motor and frequency controller are used with each blower in the system to enhance user functionality. Each unit is equipped with two blower assemblies. Frequency Controlled Motor A frequency controlled drive is installed for each direct drive blower motor. The frequency controller communicates with the microprocessor controller allowing user adjustable rpm settings via the main display. This makes field air balancing quick and easy. Field air balancing is a common after thought that can be expensive and lead to back-charges. Each time the fans are started, the frequency controlled drives control the ramp-up of fan speed. This thirty second soft start lowers the in-rush current and reduces the locked rotor amps used when sizing generators. 2-way/3-way Modulating Valve A fully modulating valve is microprocessor controlled to automatically direct the proper amount of chilled water into the cooling coil to maintain desired conditions. The standard valve pressure rating is 400 psi (2758 kpa). The valve is user configurable to be two-way or three-way. Electrical Panel The electrical panel contains the contactors, starters, overload protection devices, and input power disconnects. The panel is removable for easy access to blower motor assemblies. Programmable Input/Output Interface Module The unit provides field connections through a system programmable input/output module. Up to three additional input/output interfaces may be added to the main module. Each interface module is programmable with inputs that can be mapped to any system alarm or annunciated to outputs as a system alarm or custom (12 character) alarm. Cross Circuited Cooling Coil/ 94VO Thermal Condensate Pan Cross-circuited cooling coils connect to the incoming chilled water supply to provide greater sensitivity in cooling and dehumidification. Designed for high sensible heat ratios, the coil is constructed with copper tubes, aluminum fins, and galvanized steel end plates. Condensate pan is 94V0 thermal formed, anti-fungal, non-ferrous material for higher indoor air quality. Cooling coil is configured as V. 30% ASHRAE 52.1 Filters The filtration of conditioned air is extremely vital to maintaining the clean, particle-free environment required by electrical equipment. The system uses 30% efficient (100 microns) (ASHRAE 52.1-92), 4 (102 mm) deep filters, with full depth filter pleats. Deeper filters produce a lower pressure drop, requiring less energy during normal operation. Rear Door Kit Rear doors and system accessories, including door mounting frames and front side toe kick, ship loose to maintain system width within access limits of standard door frames. Discharge Plenum The front discharge plenum consists of a perforated metal face that discharges air towards the front of the cooling unit. The plenum is a low profile design. It's height does not exceed that of adjacent IT enclosures top mounted with cable management troughs. Plenum extensions are available to cantilever over adjacent 19" or 23" IT enclosures if it is desired to reduce discharge velocity and broadband noise emissions. 6 APC NetworkAIR IR

Standard Features Selectable Up or Down Piping Kit Choose from top or bottom piping kit. Top piping kit connects to internal stubs and turns the piping 90 upward out the back of the system. Bottom piping kit connects to internal stubs and turns the piping 90 degrees downward. (Requires access to raised floor). High Lift, Dual Float Condensate Pump The factory installed and wired condensate pump is capable of pumping 60 gal/hr (0.06 L/s) at 60 ft. (18.3 m) head. Dual Critical/Non-Critical Power Inputs The system can be optionally configured with two power feeds for critical and non-critical operation. Fans, controller, and condensate pump are critical, while electric reheat and humidification are noncritical. This allows a level of system fault tolerance and uninterruptible cooling to exist, depending on building infrastructure design (N/A 600V single input models). Network Management Card Permits multi-level access to monitoring, control, and event notification features over the user s network. Steam Generating Humidifier The humidifier utilizes a pure steam generator specifically designed for precision environmental control. The pure steam eliminates contaminating mineral deposits, potentially harmful bacteria, white dust and excessive humidity. The humidifier requires little scheduled maintenance. Automatic flushing combined with a communication link to the microprocessor controller signals when the canister is to be changed. Humidifier is proportionally controlled to meet the humidification demands of the conditioned space. The communication link to the main controller provides diagnostic capability for the humidifier. Predictive Failure Warnings Several components within the unit will provide a warning that service is needed prior to failure occurring. Main Power Circuit Breaker(s) A nonautomatic main power circuit breaker disconnects all high voltage power to the unit if necessary. The disconnect switch is accessible without removing the electric box cover. SCR Controlled Electric Reheat Electric reheat elements are low watt density, wired for 3-phase and loaded equally on all three phases, SCR controlled, and electrically and thermally protected by both automatic and manual reset thermal cut outs. Reheat coils are stainless steel, fin tubular construction. Smoke Detector The factory-installed smoke detector is designed to sense smoke in the return air stream. Upon detection of smoke, an audible and visual alarm on the microprocessor will be activated and the unit will be immediately shutdown. Twist-Lock Critical Power Feed Whip A power whip with twist-lock receptacle is provided for the critical power input. This allows easy, seamless connection to APC power distribution equipment when part of a total InfrastruXure solution. (Standard on 208V units, N/A with other voltages.) Redundant Group Control Allows up to 4 groups of IR units to communicate with each other for redundancy, demand fighting prevention, mode assist, and global sharing of certain settings. Requires standard network cable interconnection. APC NetworkAIR IR 7

Optional Features Spot Water Detector(s) The solid-state spot water detector activates an audible alarm on the controller when moisture is detected. A maximum of four detectors (spot or cable) may be installed. Side Panel Kit Side panels can be used for covering right and left sides of the system when not bayed to APC NetShelter enclosures to create a stand-alone solution. Flow Switch In-line paddle type flow switch placed in pipe during installation allows alarm or other control function to occur should a loss of chilled water flow be experienced. Circuit Setter Read-Out Provides correlation of an observed differential pressure with a volumetric flow rate of chilled water for installation and service assistance. Air Discharge Diffusers Plenum extensions installed to the left and right of the main plenum for noise reduction and increased distribution pattern. Bay Kit IR/NetShelter VX Baying kits made of 16 gauge metal enable baying of the cooling system to APC Netshelter enclosures. The baying kits are constructed to impede airflow between the two components being joined and thus prevent accidental misalignment when installing heavy equipment in IT enclosures. Cable Leak Detector A leak detection cable is placed on the floor or subfloor around all possible leak sources. If water or other conductive liquids contact the cable anywhere along its length, the master controller visually and audibly announces a leak. The 40 ft. cable may be cascaded to make custom lengths up to 1000 ft. Network Cable Various lengths of network cable are available to ship with your cooling system. The network cable is used to interconnect multiple cooling units in a redundant group, as well as to connect the network management card to your LAN. 8 APC NetworkAIR IR

Determining Cooling Capacity How to determine capacity of the NetworkAIR IR cooling unit: IT equipment requires two variables for effective cooling: air at the ideal temperature, and enough of that air made available to the equipment s air intake vents. It is entirely possible, though undesirable, to design a computer room with enough heat removal capacity, but with an inadequate volumetric flow rate of cool air supply. When this condition exists, IT equipment will be subjected to excessively high operating temperatures on a localized basis due to recirculation, and cooling equipment will operate at less than optimal efficiency. APC provides the necessary data to prevent this undesirable and preventable situation. The first table, titled Recommended Capacity Limitations shows the heat removal capacity of the NetworkAIR IR for a given set of operating conditions. The six tables following, titled Performance Specifications show the recommended maximum amount of load that should be placed upon the cooling unit solely based on volumetric limits of cool air supply. The lesser of the two capacity numbers obtained from the Recommended Capacity Limitations table and Performance Specification table should be considered the maximum load capable of being served by the NetworkAIR IR. A definition of the terms in these tables follows: IT Equipment Air Flow (cfm/kw) The average cooling air flow rate demanded by IT equipment in cubic feet per minute divided by the total actual power dissipation of IT equipment in kilowatts. Recommended Capacity Limit (kw) The corresponding maximum load in kilowatts capable of being served by the cooling unit solely based on conservation of volumetric air flow. DB ( F and C) The dry bulb temperature in degrees Fahrenheit and Celsius of the return air stream to the cooling unit. WB ( F and C) The wet bulb temperature in degrees Fahrenheit and Celsius of the return air stream to the cooling unit. CW delta T ( F) The difference in temperature in degrees Fahrenheit between chilled water entering and exiting the cooling unit. Sensible Net Capacity (BTU/HR and kw) The sensible heat removal capacity net of fan heat, of the cooling unit at stated operating conditions. Total Net Capacity (BTU/HR and kw) The total (sensible + latent) heat removal capacity net of fan heat, of the cooling unit at stated operating conditions. Sensible Heat Ratio (SHR) The sensible heat ratio of the unit at stated conditions. Sensible Heat Ratio is the ratio of sensible capacity to total capacity. CW Flow Rate (GPM and L/s) The volumetric flow rate of chilled water through the cooling unit in gallons per minute, and liters per second, that is required to result in the stated performance. Total CW Pressure Drop (PSI and kpa) The differential pressure observed between inlet and outlet chilled water connections for the stated CW flow rate. 12 APC NetworkAIR IR-CW

The total load draw for the system remains the same with one input supplying power to all critical loads and one input supplying power for all non-critical loads. In some cases, a two input system may be preferred as a means of supplying UPS power to critical loads. Single input = One electrical input for the system for all internal electrical loads.dual Input is divided into non-critical and critical loads. Non-critical = This input supplies power to all internal loads that are not considered critical during a loss of utility power. Non-Critical loads include the humidifier and electric reheat. Critical = This input supplies power to all internal loads that are considered critical. Critical loads include the controller, condensate pump, and fans. APC NetworkAIR IR-CW 21
