Abstract
A novel air conditioning system includes a compressor; an outdoor heat exchanger; an indoor heat exchanger; and a four-way valve arranged among the compressor, the outdoor heat exchanger, and the indoor heat exchanger and configured to switch to a cooling mode and a heating mode; a first separator connected between the outdoor heat exchanger and the indoor heat exchanger; an auxiliary branch connected to the indoor heat exchanger in parallel and arranged between the gas-liquid separator and the four-way valve. With the first separator, the gaseous refrigerant and the liquid refrigerant is separated, and the gaseous refrigerant is directly bypassed to an outlet of the evaporator by means of the auxiliary branch between the first separator 108 and the four-way valve, thereby reducing the resistance to the refrigerant flowing in the evaporator and raising the energy efficiency of the system.
