SOLAR HEAT PUMP
A heat pump heating system consists of the heat source system the heat pump itself and a heat distribution and storage system. Within the closed circuit of the heat pump, the refrigerant is responsible for transferring and transporting the heat.
The actual heat gain from the enviroment takes place in the heat pump's evaporator. This is where the liquid refrigerant comes into ply, which evaporates even in sub-zero temperatures, thus storing recovered energy.
The volume of the refrigerant, now in gaseous form is then drwan in and reduced by the compressor. When the refrigerant is compressed, the pressure increases significantly thus also increasing the temperature of the refrigerant.
The hot coolant continues to flow to the liquefier - a heat exchanger in which the recovered enviromental heat is transferred to the heating system.
Thanks to a cooling process, the refrigerant once again returns to liquid form. After the expansion valve has caused a reduction in pressure and temperature, the refrigerant can once again absorb thermal energy from the enviroment, and the cycle begins once again.
