2 ENERGY SAVING The reduction in investments and operation costs, together with the current regulations regarding the cost saving and environmental compatibility, are the factors becoming more and more essential in the choice of technologically advanced units, which are characterized by high performance thanks to the electronic regulation of the components. Their use in continuous yearly working applications has confirmed high reduction in operating costs, making possible remarkable strategies of energy saving and plant technological integration in all fields, particularly in the industrial one. COMPACT DESIGN, FULL EFFICIENCY The units of RAS F Kp series are designed for outdoor installation and aim to produce chilled water for air conditioning systems in service market or in industrial process applications. The units of this series are composed of one or more R290 cooling circuits and a single hydraulic circuit, which can be provided with buffer tank and/or additional pump kit. These options are located directly inside the unit s cabinet, specifically designed to maximize the capacity/surface ratio and thus to decrease the required space for outdoor installation of the unit. VERY LOW ENVIRONMENTAL IMPACT The units of RAS F Kp series are charged with an eco-friendly refrigerant: R290 Propane. It is a natural hydrocarbon which is non-toxic even at high concentrations and with excellent environment characteristics: its ozone depleting potential is null (ODP=0) and value of global heating potential is negligible (GWP=3). The optimal physical and thermodynamic characteristics of this natural refrigerant allow these units to run at high efficiency values and reduce in this way the operation costs with maximum respect of environment. FLEXIBLE CONFIGURATIONS, VARIETY OF APPLICATIONS The units of RAS F Kp series have been designed to satisfy a wide range of cooling capacity. The thermal exchange coil with external air is equipped with hydronic section for running of the unit in free-cooling mode if the external air temperature is lower than the inlet temperature of the fluid to be refrigerated, it allows the unit to run at high values of efficiency. Moreover, thanks to the several available configurations it is possible to obtain a high level of personalization of the unit depending on customers requests. OPERATING LOGICS The electronic regulation with microprocessor controls and manages all the devices installed on the unit, based on the values detected by variables during operation. From display of user s interface it is possible to visualize in real time all information regarding the regulation parameters, values of functional variables and the operation status of the unit; an internal memory records the running conditions when an alarm arises to show it then on the unit on-board display. 2

3 RAS F Kp FAMILY 2. CONSTRUCTION FEATURES The units of RAS F Kp series are designed for outdoor installation. They are The packaged air cooled liquid chillers of RAS F Kp series are extremely compact units used for cooling liquid solutions circulating in air conditioning plants of ling coils made in a single copper micro-finned pack, highly efficient plate exchan- equipped with axial fans made in composite material, condensing and free-coo- service sector or in industrial processes where it is necessary to assure excellent gers and semi-hermetic reciprocating compressors running on one, two or four performance with low environmental impact. independent cooling circuits in single configuration. In order to assure the operation of the unit in maximum safety conditions, all the components of cooling circuit The used refrigerant is propane R290 (belonging to the class of natural refrigerants). This hydrocarbon, other than having such thermodynamic characteristics allowing the units to run at high values of efficiency and cooling capacity, closed and separated from the external environment where the unit is installed. (except condensing coils) are installed inside the technical compartment which is has null or negligible indexes of environmental damage (ODP=0 and GWP=3), The technical compartment itself is equipped with an air extraction system which if compared to conventional HFC refrigerants. Moreover, propane is non-toxic is activated before the unit starts and remains active during all the period of unit even at high concentrations and is highly compatible with materials (has no corrosive effect on copper components); the only critical aspect to pay attention to exhausted or carried out to other compartments free of any kind of ignition that operation. In this way all possible gas leakages can be controlled and externally is related to a high degree of flammability. For this reason the units of this series may cause fire. A differential air switch controls exhausting fans that should be are developed selecting the components specifically designed for operation with always active during the normal operation of the unit and stops compressors in hydrocarbons and applying arrangements that assure the unit operation in conditions of maximum safety. Thanks to the applied design technology, the chillers of RAS F Kp series are able case of interruption of air extraction from the technical compartment. The units of this series are equipped with air/water coil for recovering cooling to control with high precision the fluid temperature leaving the exchanger (user capacity directly from the outside air. For this reason, installation of the unit is side), modulating the cooling capacity according to the plant s requirement, all suitable in locations with the annual thermic profile characterized by low temperatures. In fact, the benefit obtained from the free-cooling is much more noticeable at design stage, as well as the use of the best components present on automatically managed by the on-board microprocessor. High technology used when the outside air temperature is lower than the fluid to be refrigerated. Consequently, it is good to foresee glycol solutions in the hydronic circuit of the air/ to work for long periods without stop. These uni- market, make these units very reliable and thus able water coil to avoid freezing. If in the plant it is not possible to directly use this kind ts are particularly easy to install even in limited of solutions, the unit can be equipped with additional plate exchanger properly spaces, as well as for ordinary and extraordinary dimensioned (water/glycol) separating the free-cooling coil circuit from the main maintenance from the front side of the unit. circuit.

NOMENCLATURE R A S 60 1 F Kp The compressors are of alternative semi-hermetic type, specifically designed and optimized for operation with hydrocarbons and manufactured according to safety requirements for application in zone classified for presence of flammable gasses (Zone 2, gas group IIB) as per Directive ATEX 94/9/CE. The electrical motor foreseen for low current inrush (PW option) is complete with thermal protection module (installed inside the electric board). The lubrication system is of forced type, equipped with oil filters and connections for lubricant pressure detection and occurs through a high pressure pump. Each compressor, operating on a single independent circuit, is installed on rubber buffers and equipped with vibration dampers, shut-off valve on suction and discharge side, ATEX compliant electronic differential switch for oil level control, ATEX compliant oil crankcase heater and temperature probe in discharge to control the compressor discharge temperature.

It is supplied with close cell insulating material covering. Moreover the exchanger is provided with a safety water flow switch that doesn t allow the unit operation in case of low water flow to the exchanger. On refrigerant side the maximum working pressure is established at 28 relative bar. 2.6 Regenerative exchanger To assure an appropriate value of gas overheating on compressor suction side and a correct temperature of lubricating oil, each cooling circuit is equipped with a plate regenerative exchanger. This exchanger subcools the liquid leaving the condensing part and overheats gas leaving the evaporator, assuring at the same time both absence of liquid on compressor suction side and increasing the efficiency of the whole cooling circuit. On request and depending on type and number of installed compressors it is possible to equip the unit with the system of partial load with 2, 4 or 8 steps (options G2, G4 or G8), using appropriate heads managed by means of solenoid valves complete with ATEX certified coils. 2.3 Axial fans The fans for external heat-exchange coils are of axial type with 3-phase electric motor directly coupled to the impeller. The fan motors are of totally closed type with protection degree IP54, class F and provided with internal thermal protection in-built into the electrical motor winding. The blades are made of aluminum and their particular profile geometry is designed to minimize the turbulences in zone of air separation (reducing in this way the sound level and increasing efficiency). Each fan is equipped with suction noozle and protection grid against accidents, painted after construction. 2.4 Condensing coils and free-cooling The external heat-exchange condensing and free-cooling coils are made of micro-finned copper pipes and positioned in staggered rows, mechanically expanded into an aluminium finned pack to maximize the heat exchange efficiency. They are suitably sized in order to have a wide exchange surface to grant the correct operation of the units with high external air temperatures as well. In particular, the condensing section circuit is designed in such a way to keep low values of pressure drops and at the same time to assure a suitable refrigerant speed. Moreover, it is possible to partially use the condensing section surface during partial load operations and, thus, it is possible to control the working pressures controlling the refrigerant flow by means of solenoid valves and pressure transducers. In this way, when free-cooling is enabled, the fans can be always started at maximum speed and therefore to recover the maximum cooling capacity from the outside air independently from the pressure conditions or temperature. The free-cooling section of the coil exchanging with the outside air is supplied with a servo-operated 3-way valve opening the circuit when the outside air temperature is lower than the inlet temperature of fluid to be refrigerated. The particular geometry of cooper piping of this section allows to minimize the pressure drops on water side. The maximum working pressure of the condensing coils on freon side is 28 barg while the maximum working pressure of free-cooling section on fluid side is 10 barg. On demand and in case the unit is installed in a particularly aggressive environment, several coil protection treatments are available, for example, painting of copper fins (option RM), treatment with double layer of epoxy coating (option TDS) and special execution of the coil with copper pipes and fins (option RR). 2.7 Electric board and microprocessor Electric board is built in compliance with norms. Inside the cabinet, are installed all the components of the control system and the components necessary for start and thermal protection of electrical motors, all factory tested and wired. The electric board has a watertight structure, equipped with cable glands IP65/66 and ventilation system to keep the internal volume in overpressure compared to external environment. In this way the possible refrigerant leaks can not enter inside and come into contact with possible sources of ignition. Moreover, inside the electric board are installed all the control and power devices, the microprocessor electronic board provided with keyboard and display to show available functions, lock-door main switch, isolation transformer to feed auxiliary circuits, automatic switches, fuses and contactors for compressors and fans motors, terminals for cumulative alarms and remote ON/OFF, control terminal box of spring type, possibility of interface with BMS management systems. The unit is foreseen to block the electric power supply if no ventilation of compressor compartment is assured. The ventilation lack is controlled by means of differential switches that work as airflow switch. 2.8 Cooling circuits The cooling equipment of the unit is interconnected through pure copper piping. All the welding joints are made through a braze welding process and in inert ambient with double pass of weld material. Each cooling circuit is finally tested with double pressure test. The first test is made before the performance test whereas the second one is made before the unit shipping. During these tests besides the mechanical tightness, a further control of the tightness through leak detection using highly sensible tools is made. The units of this series, depending on the developed power, may have one, two or four independent cooling circuits. Thus, in case of failure on one of them, it is anyway granted the operation of the unit at 50% or 75% of its nominal characteristics. Each circuit is complete with service valve for refrigerant charge, anti-freeze probe, shut-off valve on liquid line, liquid and humidity sight glass, dehydrating filter, safety valve on high pressure side (in compliance with ATEX and foreseen for conveying of discharge out of technical compartment, at the distance from condensation fans of at least 3 meters), thermostatic expansion valve, adjustable pressure switches, high and low pressure gauges and solenoid valve on liquid line. All the components that make part of cooling circuit are suitable to work with hydrocarbons and in particular with propane and some of them (the electric coil of solenoid valve or high pressure safety valve) are ATEX certified. 2.5 User s side exchanger User s side exchanger of plate type realized in AISI 316, with single or double circuit, with channels and patented manifold which allow to reach a high heat exchange coefficient. Their design helps a uniform water distribution compatibly 4

COOLING DIAGRAM The cooling circuit is of vapor compression type and is composed by: semi-hermetic reciprocating compressors designed according to the safety requirements foreseen by the 94/9EC ATEX directive in single configuration and equipped with crankcase heater (ATEX certified), vibration dampers and stop valves in suction and discharge; coil of heat exchange with outside air, composed of one condensing section partialized for air/refrigerant thermal exchange and one free-cooling section for water/air thermal exchange (supply is managed by servo-operated 3-way valve). Partialization of condensing section, managed by solenoid valves, allows to control the working pressures independently from temperature conditions. In this way, with active free-cooling the fans can be started at maximum speed and recover the maximum cooling capacity from the external air; mechanical thermostatic expansion valve; safety valve on high pressure side in compliance with ATEX Directive foreseen for conveying of discharge in an area free from any kind of ignition; gas/liquid regenerative exchanger for the control of the correct value of gas overheating in suction of the compressors and brazed plate evaporator with single and double freon circuit. Moreover, the liquid line is equipped with stop valve, fluid level sight glass, dehydrating filter (both designed to work with hydrocarbons) and solenoid valve complete with electric coil certified ATEX. The units can be installed on the hydronic circuit, composed by single or double pump groups, equipped with expansion vessel, safety valve (calibrated at 6 relative bar), water gauge, air purge valve and drain stop valve. In case of double pump (P2 or P2H) the hydronic circuit will be equipped with stop and check valves to manage the water flow as they are not the pumps running simultaneously. On request the units can be equipped with exchangers of partial heat recovery of condensation (option RP).
