General data
During heat pump operation the energy is transferred from the outside into the building (lower heat source), and
then the air heated up to 62°C is transferred to the central heating system.
Heat accumulated inside the evaporator increases temperature of refrigerant flowing into the compressor.
Refrigerant of increased temperature and pressure ensures heat transfer inside the evaporator and returns to the
evaporator through the expansion valve. The heating water collects heat from refrigerant inside the evaporator.
Then circulating pump ensures flow of heating water into building heating system.
Heat pump shall be coupled with building heating system operating at low output, preferably underfloor
heating system or wall radiators. Higher output of heating radiators may result in poor heating during
cold days and increased costs of device operation.
