Another liquid 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 evaporator the refrigerant receives the heat energy from the brine 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 approx 5 C to approx 100 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 heating energy that the refrigerant releases in the condenser is retrieved by the heat pump s boiler section The heating medium circulates in a closed system and transports the heated water s heat energy to the house water heater and radiators heating coils Passive cooling The brine can also be circulated via a mixing valve to a heat exchanger There the brine cools the heating system s water so that comfort cooling can be maintained during the hotter periods of the year Chapter
