Page 41: Operating Principle
5.2 Operating principle GSHP19 ver. 3 Evaporator Cooling circuit Compressor Refrigerant circuit Condenser Heating circuit Expansion valve There are three closed circuits running within or through the heat pump: ● cooling circuit ● refrigerant circuit ● heating circuit. The heat pump’s operation is based on vaporization and condensation of refrigerant circulating within the pump. -
Page 42: Heating And Cooling
The high-pressure gaseous refrigerant is led into a condenser, where it releases its heat energy into the water that circulates between the heat pump and a heat sink (such as a storage tank, heating circuit, or other heating consumer). As the refrigerant releases its heat energy and its temperature drops, it condenses into a liquid. - Page 43 In this example, water is cooled down to 7 °C, and the energy taken from the water is used to heat the water in the heating system to 60 °C. Collecting heat The heat pumps can use various heat sources for collecting heat, for example: ●...
