Abstract

The invention discloses an air-conditioning system. The air-conditioning system comprises a compressor with two interdependently compressing cylinders, a reversing unit, an indoor heat exchanger, a first throttling unit, a gas-liquid separator, a second throttling unit and an indoor heat exchanger which are sequentially connected to form a refrigerant circulating loop and is characterized by further comprising a controller, the controller calculates the refrigerant throttling degrees of the first throttling unit and the second throttling unit according to the operating parameters of the air-conditioning system and determines the refrigerant throttling degree of the second throttling unit or the first throttling unit according to the proportion value between the first throttling unit and the second throttling unit. The invention further discloses a control method of the air-conditioning system. The operating energy effect of the air-conditioning system can be ensure, and the air-conditioning system can rapidly meet the operating demand.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning system and a control method thereof. Background technique [0002] The current air-conditioning system does not optimize the cycle design of the gaseous refrigerant before entering the evaporator after throttling, which causes the gaseous refrigerant to affect the heat transfer performance of the evaporator and increase the compression power consumption of the compressor, thereby affecting the energy efficiency of the air conditioner. [0003] Although the air injection enthalpy increase and double-cylinder compression technology can improve the heating capacity level of the air conditioning system at low and ultra-low temperatures, but in the control of the air conditioning system, in order to ensure the normal operation and energy efficiency of the air conditioning system, the throttling of the throttling device Regulation is extremely important.
