Problems solved by technology

However, the existing gas-liquid separators only have one or more uncontrollable oil return holes. When the actual operating state of the system changes, especially the multi-line system, it is impossible to effectively control the oil or liquid return volume of the gas-liquid separator. The operational reliability will be greatly reduced

Abstract

The invention provides a gas and liquid separator. The gas and liquid separator comprises a shell, an air inlet pipe and an air outlet pipe. One end of the air inlet pipe and one end of the air outlet pipe are located inside the shell, and the other end of the air inlet pipe and the other end of the air outlet pipe are located outside the shell and communicated with a pipeline of an air conditioning system. The air outlet pipe is provided with an oil return hole. The gas and liquid separator further comprises a second oil return device. The second oil return device comprises an oil return pipe and an oil return valve. The first end of the oil return pipe is arranged on the air outlet pipe, and the second end of the oil return pipe is communicated with a gas and liquid separator liquid storage part; the oil return valve is arranged on the oil return pipe. Because the second oil return device is arranged, the oil return amount or liquid return amount can be controlled by controlling the opening of the oil return valve on the oil return pipe. The invention further provides an air conditioner and an air conditioner liquid return control method. The oil return amount or liquid return amount of the air conditioning system is controllable, so that smooth operation of the air conditioner is guaranteed, and the reliability of the air conditioner is greatly improved.

Description

technical field [0001] The invention relates to the field of refrigeration and air conditioning, in particular to a gas-liquid separator, an air conditioner and a liquid return control method for the air conditioner. Background technique [0002] In current air conditioning systems, gas-liquid separators are used to improve system reliability. However, the existing gas-liquid separators only have one or more uncontrollable oil return holes. When the actual operating state of the system changes, especially the multi-line system, it is impossible to effectively control the oil or liquid return volume of the gas-liquid separator. The operational reliability will be significantly reduced. Contents of the invention [0003] In view of the above-mentioned current state of the art, the technical problem to be solved by the present invention is to provide a gas-liquid separator, which can effectively control the amount of oil return or liquid return. The invention also provides ...
