Here the air releases the heating energy to the refrigerant and the air s temperature drops The cold air is then blown out of the heat pump Refrigerant circuit A gas circulates in a closed system in the heat pump a refrigerant which also passes the evaporator The refrigerant has a very low boiling point In the evapor ator the refrigerant receives the heat energy from the outdoor air and starts to boil The gas that is produced during boiling is routed into an electrically powered compressor When the gas is compressed the pressure increases and the gas s temperature increases considerably from 5 C to approx 80 C From the compressor gas is forced into a heat exchanger condenser where it releases heat energy to the heating system in the house whereupon the gas is cooled and condenses to a liquid form again As the pressure is still high the refrigerant can pass an expansion valve where the pressure drops so that the refrigerant returns to its original temperature The refrigerant has now completed a full cycle It is routed to the evaporator again and the process is repeated Heat medium circuit The heat energy that the refrigerant produces in the condenser is retrieved by the climate system s water heating medium which is heated to 55 C supply temperature The heating medium circulates in a closed system and transports the heated wa ter s heating energy to the house water heater and radiators heating coils The tem
