Problems solved by technology

At present, most major air conditioner manufacturers use R32 and R290, but because R290 is a flammable refrigerant, the system charge is small, the system pressure is small, and the partial pressure of lubricating oil is large. The viscosity of the solvent and lubricating oil will increase sharply, which is prone to blockage of the system, resulting in lack of oil and refrigerant in the system, making the cooling and heating effects of the system poor, reducing the user experience effect, and the system will burn out after long-term operation compressor

Abstract

The invention discloses an air conditioner system and a control method of the air conditioner system. The air conditioner system comprises a compressor, a reversing assembly, an outdoor heat exchanger, an indoor heat exchanger, a first throttling assembly and a second throttling assembly. The first throttling assembly and the second throttling assembly are arranged between the second end of the outdoor heat exchanger and the second end of the indoor heat exchanger in parallel. The first throttling assembly comprises a first throttling device and a first valve body assembly, wherein the first throttling device and the first valve body assembly are arranged in series. The second throttling assembly comprises a second throttling device and a second valve body assembly, wherein the second throttling device and the second valve body assembly are arranged in series. The first valve body assembly and the second valve body assembly are controlled to be switched to be connected so as to enable one of the first throttling device and the second throttling device to achieve the throttling and depressurization effect. By the adoption of the air conditioner system, the blocking phenomenon can be avoided, and the good cooling and heating effect is achieved.

Description

technical field [0001] The invention relates to the technical field of refrigeration and heating, in particular to an air conditioning system and a control method thereof. Background technique [0002] Due to the high GWP (global warming potential) of the traditional refrigerants R22 and R410A, their substitutes, such as R32 and R290, have gradually emerged, especially the natural refrigerant R290, which has achieved good results. At present, most major air conditioner manufacturers use R32 and R290, but because R290 is a flammable refrigerant, the system charge is small, the system pressure is small, and the partial pressure of lubricating oil is large. The viscosity of the solvent and lubricating oil will increase sharply, which is prone to blockage of the system, resulting in lack of oil and refrigerant in the system, making the cooling and heating effects of the system poor, reducing the user experience effect, and the system will burn out after long-term operation comp...
