HOW THE HEAT PUMP WORKS
1. Heat absorbing part - Low pressure
This part of the heat pump is called the evaporator. A refrigerant with a low temperature and boiling point runs thru the evaporator. The evaporator is heated up by the surroundings which results in a evaporating of the refrigerant.
2. Pressure increasing part - High pressure
This part consists of a compressor. The compressor compresses the heated refrigerant which leads to a pressure increase which results in two things, a high raise of temperature and a high increase of the condense point.
3. Emit of heat part - High pressure
This part of the heat pump transfers the heat to the house, it is called the condenser. The refrigerant runs thru the condenser with a very high temperature and condense point. In the condenser the refrigerant is cooled down by the heating system in the house, the heat has been transferred by for example the radiators, floor heating and so on, the refrigerant is condensed.
4. Pressure lowering part – Low pressure
This part consists of an expansion valve which expands the cooled refrigerant. This lowers the pressure which results in a substantial lowering of temperature and boiling point of the refrigerant.
