6 Chapter Preface Chapter Preface This chapter mainly introduces the special requirements on the equipment room environment and the features and advantages of Liebert_DM series air conditioners (AC for short).. Special Requirements For The Equipment Room Environment The precise environment control is very important for the operation of the computers, therefore, the computers have strict requirements for the equipment room environment, which cannot be achieved by the commercial air conditioners designed for comfort. The relevant requirements mainly include the following four aspects. Temperature control: Huge amount of sensible heat is generated when computers and exchanges are operating in the equipment room, whose density is 6 to 0 times of that of the general offices. To ensure that the computers and the devices exert their optimal effect, the temperature of the equipment room is best controlled within 4 C± C; This requires that the AC units have sufficient cooling capacity and timely response regulatory capacity to cope with drastic changes in temperature, which cannot be implemented by the commercial air conditioners. Humidity control: In computer room, ultra-high or ultra-low humidity will damage the computers. The ultra-high humidity makes the air moisture condense to form condensation water in the computers, resulting in short-circuit or damage of the host hardware. The ultra-low humidity will make the static electricity generate in the computer room, making the computers unable to operate or even crash. The commercial air conditioners cannot control the humidity within the required range. Airflow / cleanliness control: Computers and exchanges will produce huge sensible heat during the operation. To eliminate the heat rapidly, The ACs are required to have large enough large cooling cycle airflow and long blowing distance. Besides, because of the strict requirement of air cleanliness, the AC should provide an airflow equivalent to the ventilating rate of 30 times per hour, so as to filter the air. The commercial ACs cannot achieve these. All-year-round running: The commercial ACs (cooling operation) are only used in summer and they only run for 8 ~ 0 hours each day. In the equipment room, however, the ACs are required to work all year round even in winter when the temperature reached -34 C outdoors.. Liebert_DM Series AC Designed For Equipment Room The Liebert_DM series AC includes units with a cooling capacity of 7.5kW and.5kw. You can configure them freely to meet different requirements of large-, medium-, and small-sized equipment rooms and base stations. Besides, the AC has precise temperature/ humidity control and reliability design, fully meeting the special use environment requirement of the equipment rooms. Special development: As a part of the integration solution to equipment room, the Liebert_DM series ACs are specially designed for the electrical devices and provides a proper environment for the running of the precise devices, such as sensitive devices, industry process devices, communication devices and computers. Considerate design: Being concerned about inter-device practical applications, the Liebert_DM series ACs are designed to keep the overall layout between devices and ensure onsite installation and maintenance. Saving space: The Liebert_DM series AC occupies 0.3 m and a total of m area is required plus the maintenance space. Precise control: The precise control system of the Liebert_DM series ACs implement precision control over indoor environment, guaranteeing the safe working and stable running of devices to a maximum degree. For the indoor unit control panel, see Figure -.

Strong adaptability to power grid: The Liebert_DM series ACs allow a wide range of voltage and provide the following distinctive functions: unique phase loss protection, phase-sequence detection and protection, automatic high-voltage & low-voltage detection and protection, self-recovery upon power failure. All-weather operation: According to the distinct heating load feature of equipment rooms, the Liebert_DM series ACs implement 4-hour running all year round in temperature ranging from -5 C to +45 C. If a Lee-Temp outdoor unit is configured, the allowed running temperature ranges from -34 C to +45 C. Strong network management: Being configured with a standard RS485 monitor interface, the Liebert_DM series ACs implement flexible automatic switchover between active and standby devices, work shift, remote turn-off and turn-on, remote alarm, and fault query and troubleshooting over standard telecommunication protocols. Easy maintenance: The Liebert_DM series ACs provide a full front maintenance structure, facilitating maintenance.

It is applicable to environment control in equipement room and computer room. Featuring high reliability, it can maintain a favorable environment for precise devices such as sensitive devices, industry process devices, communication devices and computers. The cooling kit is provided as standard and it can precisely control the ambient temperature. The heater and humidifier are provided as options and they can precisely control the ambient humidity. If the AC unit is only available for cooling, the options are not needed.

9 4 Chapter Overview The Liebert_DM AC provides a micro-processing controller that can automatically switch over to the required function (cooling or heating, dehumidifying or humidifying), based on the programmed setpoints and room ambient conditions. Each Liebert_DM AC consists of an indoor unit and an outdoor unit. Both units are installed on the floor separately. Indoor unit The Liebert_DM AC includes units with a cooling capacity of 7.5kW and.5kw, which are applicable to power supply of 380V, 3-ph. You can select them according to the actual equipment room conditions. Outdoor unit The outdoor unit adopts air cooled mode. It is classified into two models: standard model and Lee-Temp model. The Lee-Temp model can be used at lower temperature (see Table -) than the standard model..4 Main Components.4. Indoor Unit The indoor unit consists of evaporator, compressor, fan, micro-processing controller, thermal expansion valve, strainer, filter, heater (optional), humidifier (optional) and surge protective devices (SPD, optional). For option introduction, refer to.5 Options. Evaporator Adopt a fin-tube heat exchanger with high efficiency. The distributor is designed and verified according to individual model to ensure that the refrigerant is distributed evenly in each loop, improving the efficiency of the heat exchanger to a great extent.

It features large airflow, long blowing distance, direct driving and easy maintenance. Micro-processing controller Provide a simple-operation user interface with multi-level password protection, self-recovery upon power failure, high-voltage & low-voltage protection, phase loss protection, automatic phase-sequence switching upon anti-phase and rotate speed control of the outdoor fan. The expert-level fault diagnose system can automatically display current fault information to facilitate equipment maintenance by maintenance personnel. Thermal expansion valve Adopt a thermal expansion valve with external equalizer type. It collects temperature and pressure signals at the same time to accurately regulate the refrigerant flow. Strainer Filtrate the impurities generated during long-term system operation and ensure normal system operation. Filter Adopt nylon filter material with big mesh for Liebert_DM AC. The filter features compact structure and easy maintenance. It can be washed repeatedly..4. Outdoor Unit The outdoor unit consists of fan and condenser. Other than the above components, the Lee-Temp model also includes a low-temperature unit. Fan Adopt axial flow blades with low noise. The single-phase motor with high performance is customized based on the power grid of base stations, so it can work over a wide voltage range with high reliability.

10 Chapter Overview 5 Condenser Adopt a fin-tube heat exchanger with high heat dissipation and wavy fins. It is free of dust accumulation, and can be easily cleaned and maintained. Low-temperature unit Make the AC unit operate in cooling mode normally at the lowest outdoor temperature of -34 C..5 Options.5. Humidifier The humidifier can add pure water vapor (up to.5kg/hour) into the room to control the indoor humidity within ranges required by devices and computer. The humidifier consists of a steam canister with automatic flushing control function, inlet tube, drain tube, solenoid valve and steam distributor. Note. The electrode humidifier should be installed and tested in factory.. The Liebert_DM AC can control the ambient humidity only after a humidifier is installed..5. Heater A ceramic heater with positive temperature coefficient can be selected. It is safe and reliable. When the surface temperature is too high, it will reduce the heating power to avoid danger caused by over-temperature. A temperature switch is provided on the surface of the heater, and it will cut off the power of the heater when the surface temperature is too high. When the surface temperature decreases to normal, the temperature switch will restore the operation of the heater automatically..5.3 Remote Monitor The Liebert_DM AC communicates with the host computer through a configured RS485 port and receives the control of the host software. You can also select and configure a monitoring card to realize different monitoring functions. For the descriptions of the host monitoring software SiteMonitor developed by Emerson, refer to Appendix 3 SiteMonitor Software Introduction..5.4 Energy-Saving Card The Liebert_DM AC can monitor the maximum room temperature with the energy-saving card located outside the unit cabinet. The card is placed in position with high heat load and temperature. Up to four cards can be used for an AC unit. When the temperatures measured by all energy-saving cards are lower than the setpoint in Sleep Mod and only indoor fan is running, if the Sleep Mod is set to ENAB, the AC unit will turn off the indoor fan and enter the sleep mode for saving the energy..5.5 Power SPD The power SPD is used for second level (C level) lightning over-voltage protection of the AC power. It can be maintained easily and provides status indicating and alarm function. Note The power SPD should be installed in factory.

General Principles. Use copper pipes with quick thread connector to connect the indoor unit and the outdoor unit. If the pipe length exceeds the standard pipe length (see Table 4-) and straight copper pipe is used, piping joints must be brazed.. Follow standard industry procedures in selection and placement of pipe, system evacuation and charging with refrigerant (only when pipeline is too long). The standard refrigerant of the AC unit is R. 3. Give considerations to pipeline pressure drop, oil return to the compressor, to avoid oil leakage and clogging in parts of the system and minimize noise and vibration to the greatest extend. 4. Consult Emerson before installation on whether measures such as using extended piping kit are needed, if the equivalent length exceeds 50m, or if the vertical distance between the indoor unit and the outdoor unit exceeds the values in Table 4-.

The refrigerant is condensed as fluid in the condenser and sent to the evaporator (4) after being throttled by the thermostatic expansion valve (3). In the evaporator (4), the refrigerant performs heat exchange with the indoor air that is driven and circulated by the indoor fan (5) and then evaporates. The refrigerant is sent back to the compressor () to start a new circulation. The system adjusts the rotation speed of the outdoor fan (6) to retain the discharge pressure normal. The compressor () is configured with a crankcase heating strip to prevent the refrigerant from flowing back from the condenser in summer. This can protect the compressor from liquid strike during startup. Figure 4-4 Schematic diagram of the system

During fan operating, the power system stops supplying power to the fan if the condensation pressure is smaller than (Pset - ), namely Poff. The

24 Chapter 5 Micro-Processing Controller 9 control process is A -> B -> C -> D -> E -> F -> C -> B -> A -> G -> H -> I (point A corresponds to the pressure ranging from B to G). In the case of 00% voltage output, the voltage restores to MaxV after the pressure drops by bars to the point of Pmaxv. Table 5-3 lists the voltage and pressure parameters.
