Embodiment Construction

[0033] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0034] Such as figure 1 Shown is a schematic diagram of the principle of an embodiment of the air conditioning system of the present invention. In this embodiment, the air conditioning system includes: an indoor unit heat exchanger 4 , a compressor 1 and a gas-liquid separator 3 . The gas-liquid separator 3 is provided on the refrigerant flow path between the suction port of the compressor 1 and the refrigerant outlet of the indoor unit heat exchanger 4 . A refrigerant circulation mechanism may be further provided between the gas-liquid separator 3 and the indoor unit heat exchanger 4. This mechanism is used in the refrigeration process, when it is determined that there is a refrigerant accumulation in the gas-liquid separator 3 and the refrigerant accumulation exceeds When the amount of liquid accumulation of refrig...

Abstract

The invention relates to an air-conditioning system and a method for controlling liquid accumulation in a gas-liquid separator. The air-conditioning system includes: an indoor unit heat exchanger (4), a compressor (1) and a gas-liquid separator (3), and the gas-liquid separator ( 3) Set on the refrigerant flow path between the suction port of the compressor (1) and the refrigerant outlet of the indoor unit heat exchanger (4), between the gas-liquid separator (3) and the indoor There is also a refrigerant circulation mechanism between the machine heat exchangers (4), which is used in the refrigeration process, when it is determined that there is refrigerant liquid accumulation in the gas-liquid separator (3) and the refrigerant liquid accumulation exceeds the preset refrigerant liquid accumulation amount When , guide the accumulated liquid of the refrigerant in the gas-liquid separator (3) to the heat exchanger (4) of the indoor unit for evaporation. The invention can effectively solve the liquid accumulation problem of the gas-liquid separator when the air-conditioning system is refrigerated.

Description

technical field [0001] The invention relates to air-conditioning technology, in particular to an air-conditioning system and a liquid accumulation control method of a gas-liquid separator. Background technique [0002] In the air conditioning system, the function of the gas-liquid separator is usually to separate the gas and liquid at the suction port of the gas compressor. When the air conditioning system is running, if the refrigerant entering the gas-liquid separator cannot be completely evaporated, a certain amount of liquid accumulation may be generated in the gas-liquid separator, and the liquid accumulation will further reduce the amount of operating refrigerant in the air conditioning system, making the air conditioner It is difficult for the system to perform better, which affects the cooling capacity of the air-conditioning system; if there is too much liquid in the gas-liquid separator, it may be sucked in with the suction process of the compressor, causing seriou...
