Problems solved by technology
[0002] The current air-conditioning refrigeration system does not optimize the cycle design of the gaseous refrigerant after throttling and before entering the evaporator, which causes the gaseous refrigerant to affect the heat transfer performance of the evaporator and increase the compression power consumption of the compressor, thus affecting the energy efficiency of the air conditioner
Air injection enthalpy increase and two-stage compression technology can improve the heating capacity of the air conditioning system at low and ultra-low temperatures, but for the cooling conditions often used by air conditioners, the energy efficiency improvement is very limited

Abstract
The invention discloses a cooling and heating type air conditioner and a control method thereof. The cooling and heating type air conditioner comprises a dual-cylinder compressor, a reversing assembly, an outdoor heat exchanger, an indoor heat exchanger and a gas-liquid separator. The dual-cylinder compressor comprises a first gas cylinder, a second gas cylinder, a first liquid storage device and a second liquid storage device. A gas suction opening of the first gas cylinder communicates with the first liquid storage device. A gas suction opening of the second gas cylinder communicates with the second liquid storage device. The value range of the exhaust volume ratio of the second gas cylinder to the first gas cylinder is 1%-10%. The reversing assembly comprises a first valve port, a second valve port, a third valve port and a fourth valve port, and the fourth valve port is connected with the first liquid storage device. The gas-liquid separator comprises a gas outlet, a first connector and a second connector. The gas outlet is connected with the second liquid storage device. A first throttling element with a fixed opening degree is connected between the first connector and the outdoor heat exchanger in series. A second throttling element with a fixed opening degree is connected between the second connector and the indoor heat exchanger in series. According to the cooling and heating type air conditioner, the energy efficiency of the air conditioner is effectively improved.
