Heat pump operation

The function of heat pump is based on the cooling cycle. The major advantage when compared with all the other heating sources is that much of the energy spent on the operation of cooling cycle comes from the environment, while a minor percentage of energy from the electricity.

The pump fan draws air from the environment and delivers it to the evaporator which absorbs the heat.

The heat is transferred to a closed circuit and it is compressed so that the pressure and temperature increase.

Then, it moves to the condenser, where all the stored heat is transmitted to the water that flows in the circuit of underfloor heating.

The refrigerant is, then, transferred to the relief valve where it expands and comes back to the evaporator to repeat the same procedure. This is the process that is followed in the cases of heating and hot water production. As far as cooling is concerned, the operation is reversed (Cooling can be achieved when we have underfloor heating system and/or fan coils.).
