Reversible heat pump: heating and cooling with the same system

The reversible heat pump can change the direction of the refrigerant cycle and operate in both heating and cooling modes.

Heating

Transfers heat from the environment to the building.

Cooling

Removes heat from the building to the environment.

Terminals

Fan coils are suitable for heating and cooling, while underfloor cooling requires dew point control.

Key component

The four-way valve is responsible for reversing the refrigerant cycle.
