22. LY The multipurpose unit acts as a heat pump exploiting the heat of the outside air through the finned coil evaporator it raises the temperature of the water to be sent to the system through a plate heat exchanger condenser The main difference from traditional cycle reverse heat pumps is that the heated water is produced in different heat exchanger from the one used to produce cold water 2 pipe unit 4 pipe unit COOLING CIRCUIT This separates the two hot cold sections required for 4 pipe systems COMBINED PRODUCTION If the utility requires simultaneous hot and cold water the unit acts as a water heat pump controlling condensation and evaporation on two distinct plate heat exchangers associated to circulation of cold and hot water in the system It automatically changes from one configuration to another managed by on board microprocessor to optimise the spent energy depending on the demand by the utility Maximum reliability Multi circuit unit designed to provide the maximum efficiency both with full load and partial loads guaranteeing operating continuity should one of the circuits stop to facilitate maintenance Having several compressors and circuits ensures control of more steps of power yielded in both modes Built in hydronic kit Encloses the main hydraulic components available in several configurations with high or low static pressure single pump or reserve pump see configurator 2 pipe unit 4 pip
