Introduction Liebert HPM Liebert HPM is the new serie of air conditioners developed by Emerson Network Power to allow maximum flexibility of application in technological environments, from data processing centers to manned control rooms and electronic centers for telecommunication. This series includes units with a rated cooling capacity ranging from 5 to 99 kw. Complete environmental control and reliability are paramount to ensure faultless operation of computer rooms, telecom installations, data centres and technical applications. Emerson Network Power products have traditionally set the industry standards. But today s world requires more than just environmental control and reliability; it requires increasingly higher levels of overall performances. While still offering unmatched environmental control and reliability, the new Liebert HPM range raises the bar of performance in Precision Air Conditioning setting new standards in terms of Energy Efficiency, Compactness and Sound emissions. The new Liebert HPM range is available in a number of airflow versions: with upflow, downflow and displacement airflow patterns across a full range of cooling modes: direct expansion, chilled water, freecooling, dual fluid and constant (for an ultra high temperature and humidity control and air filtration).

1 Features and Benefit Features and Benefit The new Liebert HPM range The plug fan technology with generously dimensioned heat exchanger, scroll compressors and optimised cooling circuits, maximise efficiency by operating at low levels of energy consumption. This can be further enhanced by the use of Electronically Commutated Fans (EC Fan) reducing power input by 35%. We underline the complete range with all models in Displacement version and in Constant configuration. The down---flow version achieves the highest levels of efficiency (EER is 20% better than industry average). The fan in this case is positioned upstream of the evaporator optimising airflow over the coil. Also in the Under versions, silencer cartridges can be used to further reduce the sound pressure level by up to a 5dBA. The new Liebert HPM range has been designed to have the smallest possible overall footprint. The compactness of the unit is fully evident for some capacities. For instance: --- in the smaller sizes (S05 and S0) where the air outlet plenum is integrated in the unit body in a depth of only 400 mm; --- in the S23, where 23 kw in direct expansion mode have been reached with footprint of 750 x 750 mm. --- in the M29, where 29 kw have been reached with footprint of 1000 x 850 mm --- in the M47, where 47 kw, single circuit, have been reached with a footprint of 1750 x 850 mm; --- in the M5 and M, where in the 1750 x 850 mm footprint we have upflow and downflow configurations for air and water cooled units. --- in the L83 and L99, where in the 2550 x 890 mm footprint we have downflow configurations for air and water cooled units. Low sound levels are the result of fan design, optimised airflows and doubled skin insulated panels. Attention to design detail means low operational costs including product maintenance through high levels of reliability and a service friendly design. As an example, all the crucial parts of the refrigeration circuit (i.e.: thermostatic valves, sight glasses and liquid line driers) are grouped together and accessible simply by opening the front door. Energy Efficiency Plug --- in Fan All Liebert HPM units are equipped with plug fans: direct driven centrifugal fans with backward curved blades and an asynchronous external rotor motor. The new generation of these fans with specifically shaped blades, designed especially for the use in air conditioning cabinets, features a very high mechanical efficiency over a wide operating range. In addition, sound radiation is free of tonal noise at the impeller suction and discharge sides. These fans are designed to have the maximum power capacity at an intermediate operating point therefore there is no risk of motor overloading. The fans are not dependent on a minimum back pressure, as is the case with most centrifugal direct driven fans with forward curved blades. Thanks to the use of plug fans the Available External Static Pressure is adjustable on site during commissioning, with a range from 0 to 450 Pa in some models, according to the installation requirements. EC Fan (Plug---in Electronically Commutated Fan) The largest capacity Liebert HPM units can be supplied with an exclusive fan type, this enables you to greatly increase the unit s efficiency and therefore significantly reduce operating costs. EC fans [Electronically Commutated DC motors] have the added advantageof higher fan shaft motor efficiency: from 45% of 1--- phase motors, to 5% of 3---phase motors and to 85---90% of EC fans. As an example, a chilled water Liebert Liebert HPM 0 Hz--- PD--- 273159 --- 20.11.2009 1 --- 1

Features and Benefit HPM requires about 50% lower power input with this option, respect the market average value. Additional benefits are that, on start up, the Liebert HPM peak inrush current is lower than the operating current. This means the EC fan option features a true soft start.also comparedtoacfan supplied by the frequency converter, the advantages are evident and the input power is clearly inferior: from13 to 38% as a function of the working point. The internal electronics of the EC fan are integrated into Emerson Network Power controls. The EC fan design allows a new approach in regulating environmental parameters within HPAC applications. To name a few: D constant air volume D constant external static pressure D sound emission optimisation D power input optimisation D cooling capacity regulation (on request) This enables each system to be optimized for the installation. These features are available from standard Liebert HPM units supplied with the EC fan option and we can summarized that with two words: versatility and efficiency. Heat Exchanger Section: Net Sensible Capacity matters Efficiency is a fundamental requirement in all applications today. Even more so for technological applications where the operational costs are by far the most significant consideration. Sensible Heat Ratio (SHR) values of greater than 0.90 are required to reduce to a minimum the energy spent controlling humidity during normal operating conditions. Heat exchanger design and a correct air distribution within the unit are two of the most important factors required to achieve optimum performance. Liebert HPM units feature a very high coil heat exchanger surface respect the ex hanged power. Using the index [frontal Surface x Rows / refrigeration Power] values of over 100 mm2/w are obtained. Study of the components of the vector velocity through the coil: vertical speed Sophisticated design and development tools, such as Particle Image Velocimetry and Computational Fluid Dynamics are used by Emerson Network Power to identify the best components layout in order to achieve an even and pressure---equalised airflow distribution within the unit which optimises the entire coil surface area in the heat exchanging process. 1 --- 2 Liebert HPM 0 Hz---PD---273159 --- 20.11.2009

Features and Benefit Easy maintenance All components are easly accessible from the front of the room unit. The service compartment facilitates checking and setting of refrigeration circuit, without changing aeraulic conditions. The access to the compressor is possible even when the unit is operating by removing the front panel. The access to the fan is executed with the greatest care for easier interventions (maintenance and/or fan replacement). One very important feature, for example, is the possibility to check the total pressure drop of the high pressure piping using the schrader connections available in the front part of the machine(see below).

Model Configuration Versions (5 Digit) Version A Direct expansion units with air ---cooled condenser Refrigeration circuit All models are provided with a single refrigeration circuit. The compressor (1) pumps the hot gaseous refrigerant into an outdoor air---cooled condenser (2). The liquefied refrigerant arrives to a liquid receiver (3) that ensures a constant and even refrigerant flow to the thermostatic expansion valve (4) and then arrives to the evaporator (5). Here the refrigerant, thanks to the heat --- exchanged with the room air moved by the fan () --- evaporates and returns to the compressor (1); from this, the refrigerant begins a new refrigeration cycle. To maintain the correct refrigerant discharge pressure, the speed of the motor fan (8) is controlled (on---off or proportional mode). Shut---off valves are provided as standard to assist with routine maintenance. The compressor (1) has a built---in non---return valve to avoid return of liquid refrigerant from the condenser in summertime, thus protecting the compressor from undesired refrigerant slugging during the start up. A second non---return valve (7) is recommended to avoid --- in wintertime --- refrigerant migration from the liquid pipes and the receiver (3) to the condenser (2), that should be responsible of low pressure intervention at the start---up of compressor. For safety reason, a relief valve (9) is installed on the liquid receiver (3); this valve is equipped with flanged connections so that the refrigerant may be discharged to the outside. External air--- cooled condenser (2) The units may be connected with a wide range of our condensers in standard or low noise version. For technical data and performance, refer to the relevant technical documentation. Chap. 5 gives the recommended matching condenser for Liebert HPM units as a function of outdoor air temperature. Note 1. Units and external condensers are supplied separately. Note 2. The room unit refrigeration circuit is pressurised with helium at 3 bar and the condenser refrigeration circuit at 2 bar with dry air. Note 3. The customer is responsible for making connections between the Unit and the external condenser and for charging with refrigerant (standard R407C) and oil, when request. Full instructions for these operations are given in the Service Manual. 5 8 SxxUA Units 4 9 2 1 3 7 Liebert HPM 0 Hz--- PD--- 273159 --- 20.11.2009 2 --- 5

For safety reason, a relief valve (9) is installed on the liquid receiver (3); this valve is equipped with flanged connections so that the refrigerant may be discharged to the outside. Water---cooled condenser These units are provided with one very efficient stainless steel brazed---plate water---cooled condenser (2). The condenser is fitted with an head---pressure regulating valve (8) for the automatic control of condensing pressure. The units operate with mains water or closed circuit with an external Dry Cooler. When operating in a closed circuit, to avoid undesired ice formation in wintertime, it is advisable to use water/glycol mixture: refer to Chap. 5 for the percentages to be used at minimum ambient temperatures. Dry Coolers, water---glycol mixture and circulation pump(s) are normally supplied by others separately. If mains water is used, a mechanical filter must be fitted in the water circuit to protect the plate condenser (2) (for other information see the Service Manual). To reduce water and energy consumption (pump), it s advisable to adopt a cooling water control valve(bytheuser),abletostopwaterfeedingwhenunitisoff. Unit microprocessor control gives a 24V contact (10VA max, please refer to the relevant Wiring Diagram, 58 and G terminals) to drive that valve. Note. The water---cooled Liebert HPM versions are filled with the complete charge of the requested refrigerant (standard R407C). 5 4 9 SxxOW Units 1 2 7 3 8 Cooling Water 2 --- Liebert HPM 0 Hz---PD---273159 --- 20.11.2009

Model Configuration Version F Freecooler units Freecooling mode The Freecooler unit cools the air flow by means of the air refrigerant coil (5) in direct expansion rows [direct expansion mode] or, as an alternative, the air/water coil (5) in freecooling rows [freecooling mode]. Whenever the outdoor temperature is at least 5 degrees below the indoor return temperature, the water flow is cooled by an external Dry Cooler (10) and passes through the coil (5). When the external temperature is higher than ZET (Zero Energy Temperature), the water exchanges heat with the refrigerant in the water---cooled plate condenser (2). When the external temperature is below ZET, the water is cooled as much as to cool the room air directly in the air/water coil (5, freecooling rows). Refrigeration circuit All models are provided with a single refrigeration circuit. The compressor pumps the hot gaseous refrigerant into a water---cooled condenser (2). The liquefied refrigerant arrives to a liquid receiver (3) that ensures a constant and even refrigerant flow to the thermostatic expansion valve (4) and then arrives to the direct expansion rows of the evaporator (5).

To avoid undesired ice formation in wintertime, it is advisable to use water/glycol mixture: refer to the Service Manual for the percentages to be used at minimum ambient temperatures. The circulation of the water---glycol mixture is forced (the pump (11) and the water---glycol mixture are not supplied). The unit is provided with 2---way modulating valve (12) to control the glycoled---water flow passing through the water/glycol coil. A solenoid valve (13) allows the water flow to the condenser. The opening or closing signals, generated by the electronic controller, manage the valve actuator movement in order to maintain the desiderd conditions in the conditioned room.

Model Configuration Contemporary DX and FC operation In Liebert HPM units it is implemented the contemporary operation of DX (direct expansion mode) and FC (freecooling mode). In this way the air, before passing through the evaporating coil, is precooled in the the freecooling coil. Thanks to this feature the energy saving is considerably increased, during temperate seasons, exploiting the outdoor temperature that is a little bit inferior to indoor one. Furthermore the total cooling capacity is increased and can satisfy peak cooling requests. Liebert HPM: Annual Energy Consumption F unit vs W unit.

It is possible to adjust, for instance: set points, proportional or proportional+integral temperature, integrating factor and valve characteristics. It is also possible to manually adjust the valve with a suitable wrench. 3 SxxUC Units 2 1 Chilled Water (from Customer) Other Configurations (4 Digit) CONSTANT Liebert HPM Constant is the solution for systems requiring extremely precise control of temperature and humidy for the most demanding installations and stringent standards. Typical installations are metrological rooms, laboratories, textile, pharmeceutical, tobacco, paper and precision mechanical industries. Liebert HPM Constant, with ducted air delivery, allows temperature and humidity tolerances of 0.3_C and 2% R.H. respectively. This important result is achieved through an accurate and continuous variation of both cooling capacity and steam production. A special hot gas coil and a modulating valve enable the reduction of the cooling capacity from 100% to 0%. The refrigeration diagram, the relevant description and the operating mode diagrams of the icom Medium (or icom Large CDL control, option) describe very well how the Constant room units guarantee temperature and humidity within the requested tolerances.

The liquefied refrigerant arrives to a liquid receiver (3) that ensures a constant and even refrigerant flow to the thermostatic expansion valve (4) and then arrives to the evaporator (5). Here the refrigerant, thanks to the heat --- exchanged with the room air moved by the fan () --- evaporates and returns to the compressor (1); from this, the refrigerant begins a new refrigeration cycle. To maintain the correct refrigerant discharge pressure, the speed of the motor fan (8) is controlled (on---off or proportional mode). When the cooling capacity of the room unit is higher than the room load and the room temperature tends to decrease, the hot gas valve (11) opens and the hot gas coil (10) heats the treated air, maintaining the room at the requested restricted temperature conditions. Shut---off valves are provided as standard to assist with routine maintenance. The compressor (1) has a built---in non---return valve to avoid return of liquid refrigerant from the condenser in summertime, thus protecting the compressor from undesired refrigerant slugging during the start up. A second non---return valve (7) is recommended to avoid --- in wintertime --- refrigerant migration from the liquid pipes and the receiver (3) to the condenser (2), that should be responsible of low pressure intervention at the start---up of compressor. For safety reason, a relief valve (9) is installed on the liquid receiver (3); this valve is equipped with flanged connections so that the refrigerant may be discharged to the outside. External air--- cooled condenser (2) The units may be connected with a wide range of our condensers in standard or low noise version. For technical data and performance, refer to the relevant technical documentation Chap 5 gives the recommended matching condenser for Liebert HPM units as a function of outdoor air temperature. Note 1. Units and external condensers are supplied separately. Note 2. The room unit refrigeration circuit is pressurised with helium at 3 bar and the condenser refrigeration circuit at 2 bar with dry air. Note 3. The customer is responsible for making connections between the Unit and the external condenser and for charging with refrigerant (standard R407C). Full instructions for these operations are given in the Service Manual. SxxKA Units 10 5 2 8 11 1 4 9 3 7 Liebert HPM 0 Hz--- PD--- 273159 --- 20.11.2009 2 --- 13

Model Configuration Constant K/L, Version W Refrigeration circuit All models are provided with a single refrigeration circuit. The compressor (1) pumps the hot gaseous refrigerant into a water---cooled condenser (2). The liquefied refrigerant arrives to a liquid receiver (3) that ensures a constant and even refrigerant flow to the thermostatic expansion valve (4) and then arrives to the evaporator (5). Here the refrigerant, thanks to the heat --- exchanged with the room air moved by the fan () --- evaporates and returns to the compressor (1); from this, the refrigerant begins a new refrigeration cycle. When the cooling capacity of the room unit is higher than the room load and the room temperature tends to decrease, the hot gas valve (11) opens and the hot gas coil (10) heats the treated air, maintaining the room at the requested restricted temperature conditions. Shut---off valves are provided as standard to assist with routine maintenance. The compressor (1) has a built---in non---return valve to avoid return of liquid refrigerant from the condenser, thus protecting the compressor from undesirable refrigerant slugging during the start up. The second non---return valve (7) avoids refrigerant migration from the liquid pipes and the receiver (3) to the condenser (2), that should be responsible of high pressure intervention at the start---up of compressor. For safety reason, a relief valve (9) is installed on the liquid receiver (3); this valve is equipped with flanged connections so that the refrigerant may be discharged to the outside. Water---cooled condenser These units are provided with one very efficient stainless steel brazed---plate water---cooled condenser (2). The condenser is fitted with an head---pressure regulating valve (8) for the automatic control of condensing pressure. The units operate with mains water or closed circuit with an external Dry Cooler. When operating in a closed circuit, to avoid undesired ice formation in wintertime, it is advisable to use water/glycol mixture: refer to the Service Manual for the percentages to be used at minimum ambient temperatures. Dry Coolers, water---glycol mixture and circulation pump(s) are normally supplied by others separately. If mains water is used, a mechanical filter must be fitted in the water circuit to protect the plate condenser (2) (for other information see the Service Manual). Note. The water---cooled versions are filled with the complete charge of the requested refrigerant (standard R407C).

Model Configuration Displacement D Top air inlet, Front air discharge The Packaged Indoor Liebert HPM Displacement units, inject air next to the floor at low speed and take it in again from above, in the room upper part. The injected air generates a fresh air front hitting and moving the existing room air. The heat sources, on their turn, originate hot air ascensional currents to the room upper part due to natural convection. The hot air, limited and stratified above, is then taken in again by the conditioner. The air diffusion limits the mixing between injected air mass and existing air, causing a useful temperature stratification in the room. The Displacement system is suitable for industrial rooms and for telecom unmanned sites with very high specific load [kw/m 2 ]. The main advantages are: D a better efficiency (more than 10%) of the cooling process 1, acting on air with temperature higher than the room average value; D better efficiency of the ventilation process, needing lower exit speeds; D lower installation costs: the false floor is not request as per Under units. D lower operating costs: due to better efficiencies. Note.

Heat Rejections (W -- F -- H versions) Heat Rejections (W - F - H versions) Coupling of water cooled units with remote Dry Coolers The water---condensed units are provided with a water/refrigerant exchanger with braze---welded plates made of stainless steel; this advanced exchanger type gives the highest efficiency in heat exchange.inaddition,acertainoversizingofthe exchanger has been provided so as to reduce pressure drops (and energy consumption of the water pump) as much as possible and thus to allow the unit to operate with the external chiller in closed circuit, even at high outdoor temperatures. The O/UW units are designed for operating with mains water or water in closed circuit with an external chiller. When operating in a closed circuit, the water is cooled by the outdoor air in a heat exchanger; in this case, to avoid unwanted ice formation during winter, it is advisable to use a water/glycol mixture. The circulation of the water---glycol mixture is forced (the pump is not supplied). If mains water or tower water is used, when installing the unit fit a mechanical filter on the water line to protect the condenser against possible impurities contained in the water (for condenser cleaning see the service manual). Dry Coolers Our dry---coolers are built with a copper/aluminium cooling coil and axial fan(s). The main data on dry coolers is shown in the following table: Percentage of ethylene glycol mixed with water 40% 35% 30% 25% 20% 15% 10% 5% 0% 0 --- 5 --- 10 --- 15 --- 20 --- 25 Freezing temperature C Note: In the closed circuits to avoid water freezing in the cold seasons, it is strictly recommended to mix water with ethylene glycol. The suggested percentage is given in the Diagram. For safety reason, calculate the percentage at least at 5_C belowthe minimum ambient temperature. It is also recommended to check periodically the mixture: in case of leackage of the circuit, the sanitary water, used at compensation, reduces progressively the glycol percentage and increases the freezing point of the mixture! % in weight %involume Features and benefits Liebert HPD Dry Coolers are the new range of liquid coolers, able to cover rated heat exchange capacities from 8 to 400 kw. They excel above all for their efficiency, versatility and reliability, thanks to the following features: D possibility of installation with horizontal or vertical air flow with simple operations on site, with the same model of Dry Cooler, without needing any wiring or re---wiring inside the unit. D modulating fan speed regulator with phase (optional), for a continuous modulation of the fan speed, installed on the machine, wired and factory---set, thus making the connection steps on site and the unit start---up extremely easy; the fan speed regulator with phase cutoff can be selected to control up to two set---point values for the water delivery temperature of the Dry Cooler. Do not use fan speed regulator other than the approved one supplied by the manufacturer.

Technical Specifications Refrigerant (DX units only) The units are designed for being used with refrigerant R407C. Technical notes R407C ATTENTION the differences between units operating with refrigerant fluid R407C and those operating with fluid R22 are described below. Ithasbeenproventhatthechlorineinsidesomerefrigerants (HCFC and above all CFC) is harmful for the atmosphere ozone layer. The Montreal protocol, with the following amendments (London 1990, Copenhagen 92, Vienna 95, Montreal 97, Peking 99) and the new European regulation no. 2037/2000, in force since 1st October 2000, limit in time, with several expiry dates, the production and use of the HCFC refrigerants, among which R22. Attention The differences between the units operating with the fluid R407C and those operating with the fluid R22 are described below. The refrigerant R407C (HFC) does not contain chlorine and is thus absolutely suitable for the use in air conditioning systems, without damaging the ozone layer. Its main features are: D Non---azeotropic mixture made of R32/R125/R134a in which the percentage weight composition is, in ratio, 23/25/52. D Thermophysical features similar to R22. D ODP (Ozone Depletion Potential) equal to 0. D Not flammable in the air. D Low toxicity. The new HFC fluids are essentially incompatible with the mineral oils which are usually used with R12 and R22. Therefore, new synthetic lubricants based on polyester molecules have been developed for their use. Note: Considering the unique thermophysical properties of RC407C the refrigeration cycle is illustrated in the diagram below.

9 Filter section Filter section Standard filters Removable filters installed inside the unit before of fan and heat exchanger. Filtration from G4 to F5 (CN EN779 --- respectively corresponding to EU4 and EU5 accoding to Eurovent EU4/5). The folded structure of the filters gives high filtration efficiency and low pressure drop. The filter media used consists of synthetic fibre cells. The frame is made of cardboard. The additional pressure drop in comparison with G4 sdt filters are indicated in Tab. 9c. High efficiency filters Optional high efficiency filters, filtration class F, F7 and F9 in accordance with the CEN EN 779 standard, are made of fibreglass filter media. The filters are placed in V sections with a solid external frame in polypropylene, and can withstand remarkable pressure and flow variations. These filters will be installed within an additional duct on the unit top. Filter holding duct If 290 mm high filters are needed, a metal hood must be supplied to support them, installed on the top of the unit and with the same colour. For dimensions see Fig. 12.d. Clogged filter alarm A differential static pressure gauge after anf before the filter gives a signal when the filter is dirty. Fresh air kit Tab. 9a --- Comparison between air filter tests Eurovent 4/9 EN 779 EN 1882 The fresh air kit, optional, has a G3 class filter installed on the intake side of the fan and is connected to the Liebert HPM unit with a 100 mm diameter plastic duct. As the fresh air intake is positioned close to the fan suction, it will easily mix with the recirculation air. Air Filters general information Recently new test methods and configuration systems have been developed for all type of filters. In Europe, CEN is working to establish common standards, in the United States ASHRAE Standards has been in use since 198, and replaced by ANSI/ASHRAE 52.1---1992. So, in order to have a reference about different standards, see Tab. 9a and Tab 9b. There is no perfect correspondence between different standards, due to the different test methods, but the tables can be used as general guide.

11 Humidair humidifier Humidair humidifier Humidification The humidification system is provided by a HUMIDAIR electronic humidifier. The dehumidification function, which is supplied as standard when the humidifier option is installed, acts by reducing the fan speed with consequent reduction of the air flow and at the same time switching on the compressor (models A/W/F/D/H) or completely opening the chilled water three---way valve (models C). Electronic humidity control The software of the icom microprocessor control includes an algorithm which manages the HUMIDAIR electronic modulating humidifier and also provides the dehumidification function. There is also a special function which automatically prevents dehumidification if the return air temperature is below the required value. When the temperature reaches the correct value, the dehumidification function is automatically reactivated. Dehumidification control may be either of the proportional or of the on---off type, depending on the installation requirements: on---off is set as standard at the factory. HUMIDAIR electric steam humidifier HUMIDAIR is a replaceable plastic water cylinder with immersed electrodes. When an electronic current passes between the electrodes, the water is converted into the required quantity of steam. It is suitable for a large range of water qualities (with varying degrees of hardness) with the exception of demineralized water. It almost instantaneously produces clean, particle---free steam and avoids energy losses which are typical of other systems. HUMIDAIR is provided with the steam cylinder, water inlet and outlet valves and a maximum level sensor. The steam output can be adjusted within a range of values which can be chosen manually and is factory---set at 70% of the maximum capacity (see the relevant data). Humidifier features The steam is mixed with the delivery air of the evaporating coil by means of a suitable distributor. The icom controller can determine when the cylinder has to be changed. Replacing the cylinder is extremely easy and quick. A self---adaptive flow control system is fitted as standard and controls the current passing through the cylinder water.

There are no moving parts and it is not subject to dirt or vibration. Up to 5 sensors can be connected to the same flooding alarm device to control many points in the room. The alarm device is supplied with a sensor. Additional sensors can be ordered separately. Smoke alarm (Smokestat) A smoke alarm can be installed to stop the conditioning system when the presence of smoke in the intake air is perceived. This is an optical smoke detector (it uses the Tyndall effect), which absorbs very low current (100mA) and is absolutely insensitive to light or wind. Fire alarm (Firestat) In some applications the fire regulations require the installation of an alarm device (Firestat) which deactivates the air conditioner when the intake air temperature is too high.
