21 RC Group for IT Cooling COOLING CPCITY CONTROL ON SUPPLY IR TEMPERTURE The latest electronic devices require cold air entering from the front and hot air exit from the back allowing to create hot and cold aisles in Data Center, instead of keeping uniform temperature in the area. for THE PRECISION IR CONDITIONING S MIN PPLICTION: DT CENTER Data Center represents the precision air conditioning s main and most widespread application. In the latest years we witnessed the increase of data processing and the resulting growth in dimensions and energy consumption. The current financial and economical heavy crisis started at the beginning of the XXI century has dramatically highlighted the issue of energy efficiencies and environmental sustainability. The current Data Center managers showed great awareness towards this matter and transmitted their needs to suppliers. The message has been acknowledged by the whole industry: the precision air conditioning has been able to provide the most suitable answers to the needs of systems with increasingly higher energy efficiency coming from designers and current Data Center managers. These pages has the aim to inform about and update the technology state of the art, to furnish details on the methods, the indexes and the institutions of classification and certification and to provide a view of RC Group s products series and systems for the current high efficiency Data Center. TECHNOLOGY STTE OF THE RT From the beginning of the XXI century, industry has provided air conditioning systems and liquid chillers manufacturers with a new generation of components which take full advantage of electronics and the new heat exchange technologies to maximize energy efficiency. Nowadays all air conditioning systems by RC Group for Data Center extensively use these components; in detail: plug fans and axial fans equipped with EC brushless motors; scroll compressors with inverter BLDC motors ; oil-free magnetic levitation centrifugal compressors; air to gas microchannel coil heat exchangers; electronic expansion valves; two-way chilled water valves, in standard and pressure independent characterized version; PID microprocessor control systems; load sharing. s for air conditioning, it means to grant a constant cooling air temperature for the equipment (cold aisle temperature), supply air temperature, ranging from 20 C and 24 C, and to accept a return air temperature to the a/c unit (hot aisle temperature) often at 35 C if not higher. The machine selection has to be done firstly considering the needed air flow, and once identified the cabinet size suitable for such air flow, it is possible to proceed with the evaluation using RC World selection software. Energy and economical benefits due to higher working temperatures are clear: DX air conditioners: possibility to work with high evaporating temperatures with EER increasing and resulting machine size reduction; CW air conditioners: possibility to work with higher in/out chilled water temperatures with resulting size reduction and chiller increasing EER. RC Group air conditioners suitable for cooling capacity control based on supply air temperature are the direct expansion units equipped with BLDC inverter compressors and the chilled water units with 2-way valve: NEXT EVO INV DX and DW NEXT EVO CW NEXT EVO CW PLUS COOLSIDE EVO DX SYSTEM COOLSIDE EVO CW COOLROW DX COOLROW CW INVERTER COOLROW DX Inv in row version NEXT EVO CW Under Version The high efficiency achieved by current RC Group air conditioning systems allows to apply them in the latest Data Center that require: cooling capacity control on supply air temperature; uniform load distribution on all machines (load sharing). ll these machines are equipped with the new control system with microprocessor MP.COM whose main features are: Cooling capacity control on supply air temperature set point; Fans speed control on return air temperature or underfloor pressure set point; Dew-point calculation on heat Exchange coil; Serial management of main components fiftycoolyears RCGROUP Sp G_ITC_RCW_8.4 21

22 RC Group for IT Cooling UNIFORM LOD DISTRIBUTION ON LL CHILLED WTER UNITS (LOD SHRING) The electrical EC (Electronically Commutated) motors which equip the chilled water air conditioners NEXT EVO CW and COOLROW CW series have the following two characteristics: 1. possibility to follow exactly thermal load variations; 2. higher energy efficiency at partial loads. The latter point has radically changed stand-by meaning: no longer some machines at 100% and others in stand-by, but all operating machines at a partial load. Energy savings achieved are significant, as the schemes below clearly show. RC Group has developed COOL NET software for the creation of an intelligent NET that optimizes the LOD SHRING, maximizing the energy savings. Example for a plant with nr. 4 NEXT EVO CW 128 E8 4R units for chilled water feeding equipped with EC plug fans (cooling capacity 106 each): DT CENTER INDEXES / CLSSIFICTIONS INDEX PUE/DCIE Data Center energy efficiency is defined by PUE index or by DCiE that compare infrastructure total power installed (IT systems + cooling + protection + backup + miscellaneous), with the power used by IT equipment for data processing et vice versa. PUE (Power Usage Effectiveness) = Infrastructure total power / IT equipment power [/, absolute value]. DCiE (Data Center Infrastructure Efficiency) = IT equipment power / Infrastructure total power [/, percentage]. The PUE or DCiE starting value represents a reference value of energy efficiency and it identifies a test ambient for repeating further measurements. By comparing starting values with the final ones, data centers managers are able to analyse the results of possible initiatives to increase the energy efficiency and/or to evaluate energy indexes in certain working conditions (partial PUE and DCIE). In any time, it is possible to compare engaged power of IT systems with total power used by the infrastructure.

23 RC Group for IT Cooling The mission of Green Grid, a no-profit organisation, is to become the major worldwide authority in the field of efficient energy use by working very closely with the final users, technology providers and governments all over the world. mong the methods used to reach such goal we point out data collection and analysis, developing technology evaluation, procedures for the operators development. Nowadays there are still companies without a documented strategy to reduce energy consumption in the data center, even if many agree with the fact that the energy consumption data represent a growing source of concern. Green Grid provides for everyone a forum where IT operators meet to discuss the different options to increase resources efficiency. Solutions and recommendations are regularly published, and some decisions from this forum represent nowadays a sectors standard. In addition to PUE/DCiE, Green Grid is developing other indexes, such as: Carbon Usage Effectiveness (CUE TM ), Water Usage Effectiveness (WUE TM ) Data Center Productivity (DCP TM ) TIER CLSSIFICTION Functional and design features of the data center infrastructure are uniquely defined by TIER classification, developed by Uptime Institute and it is nowadays an international standard. Uptime Institute, founded in 1993, has been a pioneer in creating and promoting a final users community and they made available their own knowledge in order to improve reliability and the 24h availability in the data center and in IT organizations. Uptime Institute has tested and keeps on developing several innovations that have then become standards in the Data Center: hot / cold aisle layout; energy calculation parameters; cost analysis models; double power input specifications; TIER classification for reliability evaluation. There are 4 TIER classes: TIER I: Data Center with single distribution line/network, respectively one for Power and one for Cooling; no redundant component. vailability: 99,671% ( h/year of uninterrupted operation; down time: h/year).

26 RC Group for IT Cooling OTHER PRECISION IR CONDITIONING PPLICTIONS Despite signs of saturation, especially in Europe, Telecommunications (TLC) keep on representing the second market for close control air conditioning after Data Center. It is possible to divide the market in: FIXED TELECOMMUNICTION: telephone rooms are comparable to traditional small/medium Data Center now equipped with perimeter machines with temperature control and return air and without hot/cold aisle logic. ll current precision conditioners series by RC Group can be used for telephone rooms air conditioning; a pay-back time evaluation is needed in case of high efficiency units with or without free-cooling. MOBILE TELECOMMUNICTION: containers and small mobile telecommunication stations use small precision air conditioning, from 5 up. 20, all equipped with free-cooling section. Series available: TYLOR-MDE SERVICE BY RC GROUP Innovation, flexibility and timing, are some of the successful features in precision air conditioning. The last two play an important role in taking the most ambitious projects. Despite a wide standard products series for models numbers and multifunctions features, not all Users needs can be satisfied. In these cases RC Group, with its high skilled team, is willing to implement changes on current products or to manufacture ad hoc products for a particular installation. Thanks to taylor-made service, RC Group meant to create a virtuous circle with users/consultants and agents/distributors with a continuous exchange of requests/information leading to the creation of a suitable product and to customer loyalty. Packaged air conditioners for outdoor installation (MINIPC and MRK for outdoor installation); Packaged air conditioners for indoor installation (ENERTEL and MRK for indoor installation); Split conditioners with outdoor motocondensing (ENERGY SPLIT).

The taylor-made service, available for chillers and air conditioners, has represented RC Group trump card in taking projects of large Data Centers of important International Banks, TLC Operators, cloud computing owners. Most of installations need the use of a limited number of close control air conditioning, so all current RC Group series can be used. The direct expansion solution is the most suitable, if we consider heat load to be dissipated, but the incidental availability of chilled water used for other rooms with higher heat load makes convenient the installation of chilled water air precision conditioning. This is the case of power/ups/battery/trafo rooms of large Data Centers using the same CHW close control air conditioners widely installed in Data Halls. nother interesting opportunity belongs to seasonal availability of chilled water for summer air conditioning in the offices; in this case the best solution is represented by direct expansion machines with one additional coil (extracircuit EC) fed by chilled water from chiller and not needed for offices. Conditioner will use chilled water coil in hot season; compressors is stand-by and it works if needed and when chiller stops. lso in all of these cases, a pay-back time evaluation is necessary. 26 G_ITC_RCW_8.4 RCGROUP Sp fiftycoolyears

27 Highlights ELECTRONIC EXPNSION VLVES The electronic expansion valves have many benefits. They grant a higher energy efficiency combined with a better stability of the system. IT COOLING EFFICIENT ENERGY USE One of the main features of RC Group air conditioning series is the high energy efficiency both in design conditions and in partial load conditions that are variable conditions during the year. BLDC INVERTER SCROLL COMPRESSORS The compressor driven by an inverter varies the load continuously and the regulation of the refrigerant circuit can be easily adapted, without oscillations and transients, to the operating conditions required. The system is highly efficient since it is supplying the energy necessary to satisfy the required thermal load only; INVERTER furthermore it is possible to supply thermal or cooling energy even in case of overload conditions of the system. The working range of scroll compressors in comparison to the nominal values of cooling and thermal capacity output, varies on average from 35% to 120%, for centrifugal compressors varies instead on average from 20% to 110%. The possibility to follow regularly and progressively the refrigeration load, excluding on-off sequences of the compressor, allows to realize the heating/ cooling hydronic plant even without the use of the inertial tank.

FREE COOLING FREECOOLING The free-cooling system is an important accessory that allows you to maximize energy savings of air conditioning plant. The microprocessor controls a dual source free-cooling system: direct freecooling with direct introduction into the room of ambient air, or water indirect free-cooling with a dedicated heat exchanger. BENEFITS Dramatic reduction in power required The power required decreases with the reduction of power motor revolutions More efficient than traditional motor verage energy saving of 30% Longer lifetime (no brush and commutation erosion) Reduction of electromagnetic interference Minimal noise emission ccording to the set-point and the energy saving logic the controller activates a more affordable free-cooling system. VILBLE VERSIONS RC Group air conditioners are available in Over, Under and Displacement versions UP-FLOW IR DELIVERY (OVER) The air distribution goes from the top of the unit directly in to the room. The air flow in each area is predetermined during the design stage and it is not dependent on the actual state of the load to be dissipated. The system is normally applied in Comfort plants and in those plants having a defined low/medium room thermal loads density. DOWN-FLOW IR DELIVERY (UNDER) The air distribution goes from the bottom through the plenum between the building floor and the raised floor. This solution is usually applied in Hi-Tech room air conditioning and it is most favourable when load is uniformly distributed in all the areas of the room. DISPLCEMENT IR DELIVERY (DL) The air-conditioning system with displacement air delivery is based on the principle that the air is distributed at a very low speed, while enabling a cooling effect by convection. Every electronic equipment will absorb the amount of cold required to maintain a correct temperature level inside, through a natural convection effect. The greater is the load inside the electronic equipment, the greater is this effect. Therefore, every electronic equipment uses only the amount required to dissipate its own thermal load, which is generated by maximising the result and the energy efficiency of the system. FETURES Free cooling is a cooling technique that allows the shutdown of the compressors when the outside temperatures are low, producing a considerable reduction in electric consumption for the air conditioning system. The indirect free cooling system consists in the partial or complete cooling of the chilled water of the existing cooling system with the outside air. The direct free cooling system consists in the direct entry of the outside air into the room, if the outside air has a lower temperature than indoor air. BENEFITS Energy saving. The longer the outside temperature remains below the required temperature for cooling, higher the energy saving. HORIZONTL IR DELIVERY Cooling system for rows of racks (hot/cold aisle or in-row). Units are placed in the rows of racks that are arranged to obtain alternate cold and hot aisles. Electronic equipment contained in racks manage independently to aspire the necessary air for cooling. Cooling system for shelter. The units distribute the air inside the shelter cooling the electronic equipment directly. Different kind of air conditioners with air delivery in the upper part of shelter, ceiling level, or in the lower part of the shelter, floor level are available. mobile telecommunication air conditioner s direct free-cooling damper 28 G_ITC_RCW_8.4 RCGROUP Sp fiftycoolyears

The diagram compare the EER curves of TURBO FL with centrifugal compressors vs. screw compressors. The considerable improvement of the centrifugal unit under all load conditions is well illustrated. The following charts have been prepared in accordance with EUROVENT standards. Therefore, the air and water temperatures specified by these standards have been considered at partial load.

The compressors of the TURBO FL liquid chillers are equipped with magnetic levitation oil-free bearings which compared to traditional ball bearings, completely eliminate all the maintenance procedures of lubrication. INVERTER NO NEED OF POWER FCTOR CORRECTION The power factor of the centrifugal compressor (cos-ϕ) is always close to unity under all load conditions. This does not require the use of any power factor correction capacitors. MINIMUM STRTING CURRENT (LR) The compressors built-in inverter system is able to limit the starting current for each compressor to 5 mpere. Other types of compressors having the same capacity can produce starting currents up to hundreds of mpere. This low inrush current prevents any voltage fluctuation on the mains. Start-up transients are negligible and without any negative effect on the connected equipment (lighting systems, computer, electric- medical instruments etc.). INVERTER SYSTEM The compressor driven by an inverter varies the load continuously and the regulation of the refrigerant circuit can be easily adapted, without oscillations and transients, the operating conditions required. The system is highly efficient since it is supplying the energy necessary to satisfy the required thermal load only; furthermore it is possible to supply thermal or cooling energy even in case of overload conditions of the system. The working range, in comparison to the nominal values of cooling capacity output, varies on average from 20% to 110%. QUIET OPERTION TURBO FL machines are also extremely quiet. This promotes their use in noise sensitive locations such as old city centres, hotels, offices and residential buildings. EER [/] Water cooled liquid chiller Cooling Load RELIBILITY With their reliable operation the TURBO FL series is well suited for every application from comfort cooling, through the high-tech industrial sector and especially mission critical strategic applications (like hospitals, clean rooms, web farms, data centres, telecommunication exchanges, air-traffic control centres). Their operating reliability is guaranteed 24 hours/day for 365 days/year. FLOODED EVPORTOR The TURBO FL liquid chillers are equipped with flooded evaporator, where the refrigerant in the evaporation phase is outside of the tube bundle. This heat exchange solution allows to obtain a greater energy efficiency of the system because it reduces the differential between the refrigerant expansion temperature and the liquid cooled temperature. Moreover the circulation of the liquid inside the tubes of the heat exchanger can be varied considerably in relation to the cooling load, reducing the energy engaged by the pumping system. CLSS ENERGY EFFICIENCY The best and most accurate components applied to the chillers grants high energy efficiency with EER higher than 3,1 for air cooled units and even higher than 5,05 for water cooled units. This values satisfy the Eurovent conditions to join the energy efficiency class. HIGHEFFICIENCY CLSS GLYCOL FREE SYSTEM The accessory allows to use pure water instead of antifreeze solutions in the hydraulic circuit of the plant. This accessory is factory assembled and it don t modify the machine dimensions. n intermediate heat exchanger divides the hydraulic circuit into two parts; one part includes the chiller with the Glycol-Free hydraulic circuit with Free- Cooling coils and the centrifugal pump. The other part includes the evaporator and the plant hydraulic circuit. The Glycol-Free hydraulic system (free-cooling coil and centrifugal pump) must be filled with an antifreeze solution having a concentration suitable to the operation conditions of the machine, while the plant hydraulic system will be filled with pure water. GLYCOLFREE LOW NOISE EMISSIONS RC Group allows to select the units, not only for the required cooling capacity, but even for the units environmental acoustic impact.

40 NEXT EVO INV DX N EFFICIENT ENERGY USE The project NEXT EVO INV uses the current best technologies aimed at energy saving for an extremely efficient use of energy as scroll compressors BLDC inverter and EC supply fans. In detail: IT Cooling CONTROL OF THE COOLING CPCITY CCORDING TO IR DELIVERY TEMPERTURE The cooling capacity control is made on the air delivery temperature. COOLING SECTION Units are equipped with scroll compressors BLDC inverter that allow a modulating cooling capacity. Thermal load Cooling capacity The scroll compressor BLDC Inverter can change the load continuously and the regulation of the refrigerant circuit can be easily adapted, without oscillations and transients, to the operating conditions required. The system is highly efficient because it is supplying only the energy necessary to satisfy the required thermal load; furthermore the system can supply cooling capacity even in case of overload conditions. Models with double refrigerant circuit (D version) are equipped with one scroll compressor BLDC inverter for each refrigerant circuit. This solution ensures extreme precision in the delivery of the cooling capacity required, together with a drastic reduction of power input from the compressors. The exchanger finned coils of large surface is provided with fins with hydrophilic treatment that guarantees optimum falling water of condensation, high thermal conductivity and prevents the development of micro-organisms. Models with double refrigerant circuit (D version) are equipped with interlaced finned coil that maximizes the heat exchange in the operating condition with a single cooling circuit, cancelling the by-pass effect on the exchanger. Cut off threshold IR FLOW CONTROL CCORDING TO IR RETURN TEMPERTURE The EC plug fans modulate the air flow using as variable the distance from the temperature set point. It s possible to define the minimum and maximum air flow through dedicated parameters in order to adjusting the operation of the unit to the needs of the plant. In addition to the probe positioned on the machine, you can install the accessory remote probe to be placed in the environment to influence the most critical point of the system In case of no demand of cooling / heating, the control logic provides that the fans ensure a minimum air flow necessary to the probes to obtain a correct reading of the ambient temperature. Moreover in only dehumidification demand condition, the microprocessor control reduce the air flow to obtain the maximum dehumidification effect. ir flow Setpoint ir flow ir delivery temperature ( C) FN SECTION The Plug fans of the air handling section of the NEXT EVO INV series are directly coupled to brushless type electric motors with built-in electronic commutation system (EC) and driven by microprocessor control via MODBus; this allows a unit operation with variable air flow. Heating Setpoint Heating request differential Cooling request differential Cooling Setpoint Return temperature ( C) These EC electric motors ensuring high performances, minimum energy consumption and total absence of electromagnetic noise. The management software of the machine, specifically developed by RC Group for their precision air conditioners, allowing the better management of the system machine with a modulating logic of ventilation, cooling performances and the accessory system of direct free-cooling. CONTROL LOGIC ND OPERTION The logic PID of the microprocessor enables simultaneous control of cooling performances as a function of air delivery temperature and the air flow as a function of air return temperature or pressure in the underfloor / duct. re therefore possible following two control logics LOGIC 1 Cooling performance control as a function of air delivery temperature and of the air flow as a function of the return temperature. LOGIC 2 Cooling performance control as a function of the air delivery temperature and the air flow as a function of the underfloor / duct pressure. Follow the detailed description of the control logic. IR FLOW CONTROL S FUNCTION OF THE UNDERFLOOR OR DUCTING PRESSURE (optional accessory) The EC plug fans modulate the air flow using as variable the distance of a signal from the set point, coming from a differential pressure transmitter (optional) with pressure outlet via plastic tubing, to install underfloor or in the duct. It s possible to define the minimum and maximum air flow through dedicated parameters in order to adjusting the operation of the unit to the needs of the plant. Setpoint ir flow Differential pressure (Pa) DIRECT FREE-COOLING SYSTEM (optional accessory) The control system also manages the operation of the air conditioner equipped with a plenum for DIRECT FREE-COOLING (optional), that allows free cooling in the environment to be conditioned, directly entering outdoor air. The accessory is fully modulating and ensures a drastic reduction of power consumption of the machine, avoiding the start of the compressors. The use of this accessory includes the installation of an overpressure damper into the room to allow for the expulsion of excess air. 40 G_ITC_RCW8.4 RCGROUP Sp fiftycoolyears

48 NEXT EVO INV DW N EFFICIENT ENERGY USE The project NEXT EVO INV uses the current best technologies aimed at energy saving for an extremely efficient use of energy as scroll compressors BLDC inverter and EC supply fans. In detail: IT Cooling CONTROL OF THE COOLING CPCITY CCORDING TO IR DELIVERY TEMPERTURE The cooling capacity control is made on the air delivery temperature. COOLING SECTION Units are equipped with scroll compressors BLDC inverter that allow a modulating cooling capacity. Thermal load Cooling capacity The scroll compressor BLDC Inverter can change the load continuously and the regulation of the refrigerant circuit can be easily adapted, without oscillations and transients, to the operating conditions required. The system is highly efficient because it is supplying only the energy necessary to satisfy the required thermal load; furthermore the system can supply cooling capacity even in case of overload conditions. Models with double refrigerant circuit (D version) are equipped with one scroll compressor BLDC inverter for each refrigerant circuit. This solution ensures extreme precision in the delivery of the cooling capacity required, together with a drastic reduction of power input from the compressors. The exchanger finned coils of large surface is provided with fins with hydrophilic treatment that guarantees optimum falling water of condensation, high thermal conductivity and prevents the development of micro-organisms. Models with double refrigerant circuit (D version) are equipped with interlaced finned coil that maximizes the heat exchange in the operating condition with a single cooling circuit, cancelling the by-pass effect on the exchanger. Cut off threshold IR FLOW CONTROL CCORDING TO IR RETURN TEMPERTURE The EC plug fans modulate the air flow using as variable the distance from the temperature set point. It s possible to define the minimum and maximum air flow through dedicated parameters in order to adjusting the operation of the unit to the needs of the plant. In addition to the probe positioned on the machine, you can install the accessory remote probe to be placed in the environment to influence the most critical point of the system In case of no demand of cooling / heating, the control logic provides that the fans ensure a minimum air flow necessary to the probes to obtain a correct reading of the ambient temperature. Moreover in only dehumidification demand condition, the microprocessor control reduce the air flow to obtain the maximum dehumidification effect. ir flow Setpoint ir flow ir delivery temperature ( C) FN SECTION The Plug fans of the air handling section of the NEXT EVO INV series are directly coupled to brushless type electric motors with built-in electronic commutation system (EC) and driven by microprocessor control via MODBus; this allows a unit operation with variable air flow. Heating Setpoint Heating request differential Cooling request differential Cooling Setpoint Return temperature ( C) These EC electric motors ensuring high performances, minimum energy consumption and total absence of electromagnetic noise. The management software of the machine, specifically developed by RC Group for their precision air conditioners, allowing the better management of the system machine with a modulating logic of ventilation, cooling performances and the accessory system of direct free-cooling. CONTROL LOGIC ND OPERTION The logic PID of the microprocessor enables simultaneous control of cooling performances as a function of air delivery temperature and the air flow as a function of air return temperature or pressure in the underfloor / duct. re therefore possible following two control logics LOGIC 1 Cooling performance control as a function of air delivery temperature and of the air flow as a function of the return temperature. LOGIC 2 Cooling performance control as a function of the air delivery temperature and the air flow as a function of the underfloor / duct pressure. Follow the detailed description of the control logic. IR FLOW CONTROL S FUNCTION OF THE UNDERFLOOR OR DUCTING PRESSURE (optional accessory) The EC plug fans modulate the air flow using as variable the distance of a signal from the set point, coming from a differential pressure transmitter (optional) with pressure outlet via plastic tubing, to install underfloor or in the duct. It s possible to define the minimum and maximum air flow through dedicated parameters in order to adjusting the operation of the unit to the needs of the plant. Setpoint ir flow Differential pressure (Pa) DIRECT FREE-COOLING SYSTEM (optional accessory) The control system also manages the operation of the air conditioner equipped with a plenum for DIRECT FREE-COOLING (optional), that allows free cooling in the environment to be conditioned, directly entering outdoor air. The accessory is fully modulating and ensures a drastic reduction of power consumption of the machine, avoiding the start of the compressors. The use of this accessory includes the installation of an overpressure damper into the room to allow for the expulsion of excess air. 48 G_ITC_RCW8.4 RCGROUP Sp fiftycoolyears

49 IT Cooling INDIRECT FREE-COOLING SYSTEM (optional accessory) The control system also manages the operation of the air conditioner equipped with an INDIRECT FREE-COOLING system (optional). This system consists of one water cooling coil with water 2-way proportional valve, condensing control valve. The cooling coil is installed in the return air stream just after the filter section. In this way the air is partially or totally cooled before entering the main cooling coil ensuring a drastic reduction of power consumption of the machine. This working mode can be obtained by integrating the FREE-COOLING system with the water circuit of the DW machine and connecting them to an external dissipation system (option, DRY COOLER series or DRY COOLER PF series) and to a pumping group (PWU, option). NEXT EVO INV DW When ambient temperatures are below 5 C, the FREE-COOLING system is capable of providing total system capacity without having to call for operation of the compressor/s (total free cooling). t ambient temperatures between 5 C and 21 C the FREE-COOLING provides pre-cooling of the handled air, activating the compressor/s only to provide the cooling capacity necessary for the full balance of the room load (partial free cooling). The system is fully managed by the microprocessor control system installed as standard on the unit.
