6 STORING TEMPERATURE If the machine is not installed on receipt and is stored for a long time, store it in a protected place, at temperatures ranging between -30 C and 50 C in absence of superficial condensation and direct sun light. WORKING LOGIC Multifunction liquid chiller with independent or simultaneous production of chilled and hot water for 4 pipes plants. WORKING LOGIC According to the request, the unit can produce chilled water and hot water for heating, as indicated in the below scheme, that summarizes the various working conditions. The unit cooling and heating functions are enabled by selectors placed on the electric board. The pumps indicated in the scheme are optional accessories and they are factory installed inside the chiller. The pumps are active only when the relative working mode is enabled. 4 PIPES PLANT Cooling selector Heating selector ON REMOTE OFF ON REMOTE OFF MULTIPLO PF can produce chilled water or hot water with variable loads up to 50% of the nominal. Unit equipped with two compressors can partialize their operation so as to obtain different working conditions as per following table: Component On Component Off Cool % UNITS EQUIPPED WITH 2 COMPRESSORS Heat % Compressor 1 Compressor 2 Cool % UNIT EQUIPPED WITH 1 COMPRESSOR Heat % Compressor Defrosting Defrosting Defrosting 6 RC GROUP S.p.A.

18 IDEA : DYNAMIC CONTROL SYSTEM OF DEFROSTING CYCLES RC GROUP PATENTED the dynamic control system of defrosting cycles which is called IDEA (Intelligent Defrosting system for Energy-saving Applications). Unlike the traditional defrosting systems (fixed time or pressostatic at static reading), IDEA is able to identify the actual ice presence on the evaporating coil in order to start the defrosting cycle only when it is necessary. This allows an yearly energy saving ranging from 15% to 20%. Moreover, the system is totally automatic, it does not demand the introduction of any limit control parameter and it conforms to all climatic conditions. The advantages of the dynamic system can be easily summarised. First of all, the heat pump starts defrosting cycles only when they are really necessary. In this way undesired defrosting cycles are avoided and the temporal sequence is optimized, reducing or increasing it according to the thermo-hygrometric conditions of the outdoor air. Another system s advantage is that it does not demand human intervention. The other systems demand the definition of limit values: as everyone knows, not always those who handle a chillers have the necessary skill to do it, therefore they can often make serious planning mistakes or they can tamper with the system while it is working. Moreover, during plant working, the conditions of the evaporating coil can change because of the dirt which has formed: IDEA dynamic system is able to conform to the changing conditions. The IDEA system does not demand any human intervention because it is only based on the dynamic reading of working parameters, which are absolutely objective data that are not subject to mistakes. In short, the advantages are the following: the optimized heat pump working the optimized plant working the yearly working saving which ranges between 15% and 20%. the total absence of planning mistakes the reduced compressor wear, therefore an higher duration of the heat pump 18 RC GROUP S.p.A.
