THIS IS HOW THE HEAT PUMP WORKS

1. The Heat absorbing section – Low pressure
This part of the heat pump is called evaporator. The evaporator runs a refrigerant with a very low temperature and the boiling point. The evaporator is heated by the surroundings and this causes the refrigerant to evaporate inside.

2. Pressure boost part – High pressure
This part consists of a compressor. The heated refrigerant is compressed and pressure rise means that both the temperature and the condensation point rises sharply.

3. Heat emitting portion – High pressure
This part of the heat pump transfers the heat to the house and is called, the condenser. The refrigerant passes through the condenser with a very high temperature and condensing point. In the condenser, the refrigerant is cooled by the heating system (eg radiators, floor heating), causing the refrigerant to condense.

4. Pressure Lowering part – Low pressure
This part consists of an expansion device. The liquid refrigerant expands and the pressure reduction means that both the temperature and its boiling point falls sharply.
