Functionality and animation

A heat pump heating system consists of the heat source system, the heat pump itself and a heat distribution and storage system. Nowadays, heat is normally transferred via low-temperature heating systems which have already become the standard for new building projects. These types of systems can be installed either as underfloor, wall or radiator heating systems.

Within the closed circuit of the heat pump, the refrigerant is responsible for transferring and transporting the heat.

The actual heat gain from the environment takes place in the heat pump’s evaporator. This is where the liquid refrigerant comes into play, which boils and evaporates even in extremely low temperatures, thus storing the generated energy.

The volume of the refrigerant, now in gaseous form, is then reduced in the secondary compressor. When the refrigerant is compressed, the pressure increases significantly, thus also increasing the temperature of the refrigerant.

The hot refrigerant continues to flow to the liquefier – a heat exchanger in which the recovered environmental heat is transferred to the heating system.

Thanks to a cooling process, the refrigerant now returns to liquid state and, after the expansion valve has caused a reduction in pressure and temperature, it can reabsorb heat from the environment, and the cycle starts from the beginning.
