Notes on the documentation 20020213395_00 flexoTHERM exclusive Installation and maintenance instructions 72 Notes on the documentation2.1 Observing other applicable documents▶ You must observe all the operating and installation in-structions included with the system components.2.2 Storing documents▶ Pass these instructions and all other applicable docu-ments on to the system operator.2.3 Applicability of the instructionsThese instructions apply only to:ProductVWF 57/4 230VVWF 87/4 230VVWF 117/4 230V3 System overview3.1 Heat pump system designABABThe heat pump system consists of the following components:– Heat pump– System controller (from VRC 700)– Outside temperature sensor with DCF receiver– System sensor, if required– With ground heat source: Ground sensor– With well water heat source: Groundwater moduleThe heat pump system generates heat for heating installa-tions and in hot water generation by extracting the thermalenergy from a heat source circuit and releasing this intothe heating circuit via the internal refrigeration circuit. At thesame time, there is an opportunity for active cooling to takeplace via circulation reversal. The heat pump can be connec-ted to two different types of heat source. This includes geo-thermal energy and groundwater, whereby the heat source isconnected to the heat pump via a transfer station connectedbetween the two.3.1.1 Heat pump– Fulfils the heating demand of the system controller downto a minimum outside temperature and up to a maximumtarget flow temperature.– Fulfils the cooling requirements of the system controllerup to a maximum source temperature.– Hot water generation with external domestic hot watercylinder3.1.2 Groundwater module– Heat transfer from the groundwater to the brine heattransfer medium in the heat pump.3.1.3 Passive cooling module (optional)– When using ground or groundwater as a heat source,the heat of the heating water is transferred to the heatsource medium purely using circulation pumps and valveswitching. |
