ELFOENERGY LARGE COST OR RELIABILITY? THE DILEMMA OF MODERN SYSTEM ENGINEERING APPLICATIONS Air-conditioning systems in trade centres influence both the starting investment and monthly management costs, for the whole of their working lives. This theme is even more relevant in residential applications with centralised systems. Furthermore, maximum working flexibility requirements should be added to that, in serving different users while avoiding wasting energy and thus, money. Finally, there are several industrial applications which require chilled water as service fluid, process fluid or vector fluid for operator comfort and for conserving goods and enabling cycles to function correctly. Furthermore, in all these cases, the working reliability of the system is decisive. THE HIGH EFFICIENCY HYDRONIC SYSTEMS ARE EXTREMELY VERSATILE, RELIABLE AND WIDESPREAD Despite their apparently low costs, split, multi-split and VRF direct expansion systems have a lot of limits in these applications. For example, they require a separate system for primary air treatment. The pipes that contain the refrigerant cross the served rooms and therefore they are subject to restrictions and use limitations. They cannot operate in the freecooling mode, the high efficiency and convenient mode that allows energy savings. the hydronic systems are certainly more complete and versatile. They make it possible to adopt various types of terminals in the served environment, from fan coil units exposed or integrated in the furnishings, up to radiant or induction systems. They are also irreplaceable in the service and process industrial applications. The main component performances, like air-cooled liquid chiller, are checked and certificated by Eurovent. CLIVET CHILLERS REDUCE CONSUMPTION AND ARE COMPACT AND RELIABLE With over twenty years of technological evolution, Clivet liquid chillers and heat pumps represent the state of the art in air-conditioning in residential, trade and industrial environments. Their success is based on high energy efficiency, compactness and management and maintenance simplicity, with wide versatility in the choice of the most suitable model for the specific use.

ELFOENERGY LARGE ELFOEnergy LARGE TECHNOLOGY IS THE ENERGY REFERENCE POINT FOR LIQUID CHILLERS MAXIMUM EFFICIENCY IS ASSURED BETWEEN THE % AND THE % OF THE SYSTEM LOAD For maximum loads taking place only for a few hours of functioning per year. The high efficiency at partial loads of ELFOEnergy LARGE makes it much more competitive and efficient than other solutions. THE MODULAR SCROLL IS THE EXCELLENT SOLUTION FOR PARTIAL LOAD * EUROVENT (ESEER) supply times reference and ARI (IPLV) reference for seasonal efficiency calculations. ELFOEnergy LARGE uses Scroll-type high-efficiency compressors, with optimized spirals. Main advantages are: Compressors manufactured in large numbers at industrial level, with strict quality checks and highest reliability thanks to the elevated production volumes. With two different-sized compressors, in order to achive more adjustment steps. So it is possible to supply for usage only the energy that is actually require. Efficiency increases by over 0% when operating at partial loads, thanks to the larger heat exchange surfaces available. The electronic expansion valve contributes to the excellent performance (EEV) it adapts rapidly and precisely to the actual load required for usage, and the high performance heat exchangers. Example refers to a WSAT-XEE, EXCELLENCE. Version. External temperature equal to C / 0 C / C, respectively. VERY HIGH HEAT EXCHANGE EFFICIENCY Thanks to the external ELFOEnergy LARGE coils, equipped with wide frontal surfaces and reduced depth, the following is obtained: An improvement in the working temperature of the chiller circuit and, therefore, its efficiency, since the approach between the air temperature and the temperature of the chiller fluid inside the exchanger is reduced; A reduction in consumption by the fans, thanks to the reduced depth of the exchanger which decreases air flow renewal drops. Furthermore, the automatic fan speed control, supplied in series, minimises the air renewal air requirement to function correctly and therefore further reduces consumption; A decrease in the sound level, since greater surfaces enable slower air speed in the exchangers. ECOBREEZE ELECTRONICALLY-CONTROLLED FAN TECHNOLOGY The external axial fans are equipped with an innovative Winglet blade profile with an integrated deflector, which is able to increase aerodynamic efficiency. This results in a % reduction in consumption. The average acoustic emission is db less then traditional fans. Using ECOBREEZE the external rotary electric motor is operated by a continuous magnetic switching of the stator, induced by integrated electronic control. The advantages are: 0% increase in efficiency thanks to the brushless technology and the special electricity supply; Increase in the working life, thanks to the elimination of the brush wear; Reduction in the electrical consumption by the system, thanks to a drastic reduction of the inrush current for the fans obtained using the integrated Soft start function. Note: ECOBREEZE is supplied as standard in the EXCELLENCE version COMPLETELY AUTOMATIC FUNCTIONING The microprocessor controller manages functioning automatically in line with maximum efficiency criteria, enables up to units to be coordinated in a local network (Master-Slave function) and includes numerous safety functions and the management of any alarms. The interface terminal is equipped with a backlit graphic display and a multifunction access keyboard. The multi-level menu is protected by passwords which are differentiated by different user types. The daily / weekly clock programmer function is standard. Thanks to its attractive design, the interface terminal can also be positioned inside the rooms being serviced or in a special system control room. BTE00GB-0

ELFOENERGY LARGE ELFOEnergy LARGE TECHNOLOGY ENABLES THE SYSTEM TO BE INDUSTRIALISED ELFOEnergy LARGE can be supplied complete with system components which are often provided as external to units. Thus reducing: Design time: all the accessories are created to guarantee the best overall performance; Installation costs: the accessories which are already connected manually, electrically wired and individually checked are ready to start working immediately; Dimension: integration of system members into the unit reduces technical spaces and increases the space available for other uses. The slim line structure enables it to be positioned even on terraces or in external service corridors. THE ON-BOARD PUMPS ARE VERSATILE, READY-FOR-USE AND RELIABLE The various solutions available are: Standard pump, with a wide range of available heads. Standard pump with emergency pump. The on-board microprocessor balances its working hours and in case of any breakdown signals the fault and automatically activates the reserve pump. HYDROPACK, the modular solution with two parallel pumps. Automatically reduces water flow in critical conditions, avoiding blocks due to overloading and consequential interventions by specialised technical personnel. It is very useful during start-up, during re-start after a pause in working (e.g. a weekend) or after a long period of inactivity. In case of any pump breakdowns, the unit continues to function with 0% of the nominal flow. EVEN THE STORAGE TANK AND THE PRIMARY CIRCUIT CAN BE INTEGRATED ON-BOARD A connection to the secondary use circuit is all that's needed. In this way, the system results even more simple and reliable. The units are complete with rapid connections on the hydraulic side, which further reduces set-up times by eliminating pipe threading operations. Furthermore, other system components are also available as accessories, such as hydraulic attachments reported on the external walls of the unit (as standard with pumps and/or storage tank) and the required water filter. ELFOEnergy LARGE MAY INCLUDE MOST OF SYSTEM COMPONENTS STANDARD RAPID CONNECTIONS Gasket Housing Groove Bolt/Nut FREE HOT WATER Condensation heat recovery: Partial: recovers around 0% of the available heat (desuperheater); Total: recovers 0% of available heat. Free hot water production for : Supplying hot-water coils for post-heating; Producing domestic hot water (with the intermediate exchanger); Other processes or operations. IT EXPLOITS EXTERNAL AIR FOR COOLING WITHOUT ACTIVATING THE COMPRESSORS In the FREE-COOLING configuration, as soon as the external conditions enable it, the unit is able to cool the liquid reducing compressor functioning up to their complete withdrawal. This configuration is particularly useful in applications with a high number of room loads, since it notably reduces unit energy consumption and compressor wear. BTE00GB-0

Δ P [kpa] ELFOENERGY LARGE CONFIGURATIONS Consult the appropriate table, shown in the final section, to verify the compatibility between the different options. B - WATER LOW TEMPERATURE Configuration also known as "Brine". Enables a non-freezable solution to be cooled (for instance, water and ethylene glycol in appropriate quantities) up to a temperature of between + C and C. Includes: - Appropriate exchangers, complete with thick closed-cell insulation; - Electronic-type expansion valve, functional calibration and safety devices adapted to the particulars of use. In the selection phase, it is necessary to indicate the type of function required, and the unit will be optimised with: - Unit with single working set-point (only at low temperature) - Unit with double working set-point. The unit in this configuration have a different operation field, indicated on the previous pages. In the low temperature operation, some partialisation degrees could be not available. For more information, contact our Sales Department. D - PARTIAL ENERGY RECOVERY Configuration which allows hot water production free-of-charge during the cooling function, thanks to the recovery of part of the condensation heat which would otherwise be disposed of into the external heat source. This configuration is also known as "desuperheating coil". It is made up of brazed-plate exchanger in AISI stainless steel which is ideal for recovering around a quarter of the heating capacity of the unit (equal to the sum of the cooling capacity and the absorbed power input of the compressors). EEV D T T RW in 0 C RW out C AE C The partial recovery device is considered to be working when it is supplied by the flow of water to be heated.

TW out C TW in C When the temperature of the water to be heated is particularly low, it is opportune to insert a flow regulation valve in the hydraulic circuit, to maintain the recovery output temperature at higher than C and thus avoid refrigerant condensation in the partial energy recovery device.

ELFOENERGY LARGE R - TOTAL ENERGY RECOVERY Configuration which allows hot water production free-of-charge during the cooling function, thanks to the total recovery of the condensation heat which would otherwise be discharge into the external heat source. This solution increases the overall efficiency of the system in all cases in which a high-level of hot water production is requested. It is made up of Stainless steel brazed plate heat exchanger, which is ideal for recovering the entire unit heating capacity (equal to the sum of the cooling capacity and the absorbed power input of the compressors), from the on-of type solenoid valves, the temperature sensors for the hot water circuit supply and return and the relative integrated logic controller with two partialisation steps. La disponibilità di acqua calda è sempre subordinata alla produzione di acqua refrigerata. Si veda il seguente esempio:. Cooling capacity request = 0% / Heat capacity request = 0% Cooling capacity production only.. Cooling capacity request = 0% / Heat capacity request = 0% Cooling capacity production and heat capacity production by recovery.. Cooling capacity request = 0% / Heat capacity request = 0% Cooling capacity production and heat capacity production by recovery, equals 0% of the requested heat capacity. To avoid constant switching in the cooling circuit should be added to a adequate capacity storage tank in the hot water circuit of the system. If the hot water circulation is not present on the heat recovery exchanger, the maximum inlet air temperature decreases of about C compared to units without 'Total Energy Recovery'. TOTAL ENERGY RECOVERY OPERATING When hot water is required, the condensing coil is turned off. The condensation takes place entirely in the recovery circuit. TOTAL ENERGY RECOVERY NOT OPERATING When the set-point recovery is fulfilled, the coil is reactivated. In this condition the total recovery circuit operates as a partial recovery (desuperheater).

ELFOENERGY LARGE FCD - DIRECT FREE-COOLING Configuration which enables great savings on the management costs of the system in applications which require chilled water even during cold seasons like, for instance, industrial processes, data centres, telecommunications, technological applications and trade centres. When the external air temperature is less than the temperature of the return water in the system, the FREE-COOLING system recovers coolness from outdoor and reduces the compressor working up to their being withdrawn completely. The higher the temperature of the chilled water in the system (e.g. - C instead of - C), the greater the field of application of the FREE-COOLING system and, therefore, the energy saving. USING UNFREEZABLE SOLUTIONS The FREE-COOLING configuration is particularly indicated in buildings where, at least at certain times of the year, the external air temperature also reaches very low values. For this reason, the liquid must be protected from the risk of freezing, typically by adding an appropriate anti-freeze substance such as ethylene glycol. The percentage of glycol in the solution depends on the minimum temperature value foreseen in the installation area, and in any case, remains within the main parameters of the system design. TECHNICAL DESCRIPTION In comparison with standard units, Clivet units in the direct FREE-COOLING configuration also include: three-way switching valve with on/off regulation Finned water-air COIL exchanger (FREE-COOLING coil) additional outdoor air temperature sensor and control logic dedicated flush hydraulic connections. MANAGEMENT LOGIC There are three main function modes, which can be differentiated in essence by the position of the three-way switching valve and by the number of active compressors. T AE C (A) SUMMER SEASON In the summer, with external air temperatures greater than the return temperature of the system liquid, the three-way valve is switched in such a way as to exclude the FREE-COOLING coils. The cooling of the liquid is referred to the direct expansion circuit, via the workings of the compressors as in a traditional chiller. (B) INTERMEDIATE SEASON During the intermediate season, or rather when the external air temperature is a little less than the temperature of the return water in the system, when the system senses that the external air temperature conditions are favourable: it switches the position of the three-way valve forcing the solution to transit through the FREE-COOLING coils before reaching the evaporator; it puts the fans to their maximum speed to exploit as much as possible the solution cooling using the outdoor air ; it undertakes the initial cooling of the solution in a "natural and free" way; it supplies any missing capacity through the chiller cycle, using the compressors functioning partially (the absorbed power input is proportional to the level of partialisation). In case of an increase in the external air temperature, the microprocessor automatically converts the unit functioning to the summer setting, guaranteeing the conditions requested by the user at all times. EEV TW out C EEV TW in C T A AE C (C) WINTER SEASON During the winter season, with the temperature of the external air lower than the temperature of the return water in the system, the system senses that conditions are favourable for the FREE-COOLING function: the three-way valve is switched as in the previous case, forcing the solution to transit through the FREE-COOLING coils before reaching the evaporator; the external air temperature brings the solution to the FREE-COOLING coil output already at the temperature requested by the user; the microprocessor management totally deactivates all the compressors supplying all the requested cooling capacity AT NO COST, in contrast to traditional chillers. The difference between the outdoor air temperature and that requested by the user can also be such as to lower the solution temperature at the FREE-COOLING coil output to below the set-point requested for this use. This is a condition which does not compromise unit safety thanks to the presence of anti-freeze in the solution. The microprocessor modulates the fan speed until their withdrawal. If, with all the fans switched off, the temperature continues to go down, the three-way valve automatically positions itself in the summer setting, thus enabling the set-point to be maintained.

DT [ C] ELFOENERGY LARGE UNIT PERFORMANCES IN THE DIRECT FREE-COOLING CONFIGURATION The unit performance in the direct FREE-COOLING configuration also depends on the antifreeze percentage used in the circuit and are shown below in two main operating modes.
