The two paths of refrigerant come out and then are converged into the room. The refrigerant entering the room enters the high temperature evaporator and the low temperature evaporator respectively, the refrigerant exiting the high temperature evaporator enters the second air suction port of the compressor, and the refrigerant exiting the low temperature evaporator enters the first air suction port of the compressor (the high temperature evaporator corresponds to the high temperature condenser).
