Heat pump is a device in which the refrigerant R134a is continuously changing the shape from gas to liquid. It pumps out the solar energy from the air in the room and together with electrical energy consumed by compressor it gives out the total heating capacity which is accumulated in the water storage tank.
Evaporator is an air-refrigerant heat exchanger. In the evaporator the refrigerant is vaporized at low pressure and relatively low temperature. Because of vaporization the heat transfer from air to refrigerant begins. Vaporized refrigerant comes in the compressor where the pressure increases and so does temperature.
From compressor the vaporized and high temperature steam goes in the condenser (refrigerant-water) where again the heat is transferred from refrigerant to water. The refrigerant is now in liquid shape at a high pressure. After it flows through the expansion valve it reaches the basic shape and the process begins again. The circuit is in process until the water temperature in the water storage tank reaches the set point.
