How does a heat pump heat pump?
A simple principle, but very special!
Operation warmtepompEen heat pump draws heat to the air, to the water or to the Earth and passes them to the heating system.The free natural energy is first to the heat exchanger (evaporator) of the heat pump. Here is the liquid refrigerant (working fluid), which now takes up the warmth of the energy source and evaporates. The compressor squeezes the gaseous working fluid and sucks this together. The pressure is on, the temperature rises. Then creates a second heat exchanger (condenser) sure that the heat in the circulation system of the heating. Finally a pressure reduction through the expansion valve and the circulation starts all over again. Free natural low-value energy is useful high-quality energy.
Water from an open or closed source is pumped to the heat pump. The water, the temperature of the surrounding soil. Then gives off heat the water to a refrigerant. By compressing the refrigerant by a compressor creates heat, this heat is transmitted to the heating system in a house or building.
Then condenses, expands and the refrigerant evaporates again, all this forms a closed loop. Geothermal energy is in fact based on a very simple principle. Simultaneous to the process, the water is brought back to where the energy is extracted in the Earth or in the closed source.
If cooling is desired, the water of the verwarmingcircuit circulated and along a heat exchanger. This takes the cold heat exchanger on the water that is in the source. The heat from the home or the building is simultaneously issued to the return water from the source. This is the excess heat back into the ground. This can be used in the cold period of the year as energy for heating. Through the use of a heat pump with cooling it is possible to put on a cheap and energy-efficient way to cool a building.
