In the reverse cycle the cooling system has the same operation as the system that works only with cooling, the difference is detected only by the presence of a reversing solenoid valve. When the equipment is in the heating function this valve is activated by inverting the refrigerant circuit making the condenser an evaporator and making an evaporator an
condenser. In this way heat is absorbed from the external environment by the condensing unit and given to the indoor environment by the evaporator unit.
