Air conditioner outdoor unit and air conditioner

Abstract

The invention relates to the field of air conditioners, in particular to an air conditioner outdoor unit and an air conditioner. The invention aims to solve the problem of disturbance of the gas supply pipeline caused by the high flow velocity of the refrigerant in the gas supply pipeline and the problem of shortened service life caused by the liquid return of the compressor. For this purpose, the outdoor unit of the present invention includes a pressure container arranged on the gas supply pipeline, the pressure vessel includes a container body, the container body forms at least one cavity with a diameter larger than that of the gas supply pipeline to reduce the flow rate of the refrigerant, and the pressure vessel has a gas The liquid separation function makes the refrigerant flowing out of the refrigerant outlet a gaseous refrigerant. The invention reduces the flow velocity of the refrigerant in the gas supply pipeline through the pressure vessel and allows the refrigerant to enter the compressor in gaseous form through the gas supply enthalpy increasing interface, which can reduce the vibration of the gas supply pipeline and avoid liquid return of the compressor to increase the life of the compressor.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an outdoor air conditioner unit and an air conditioner. Background technique [0002] The compressor is the core device of the air conditioner, and it is usually installed on the outdoor unit of the air conditioner. The working performance of the compressor in the low temperature environment is limited. The characteristics of the air-supplementing and enthalpy-increasing compressor enable it to increase the exhaust volume of the system and reduce the exhaust temperature of the compressor in a low-temperature environment, which can ensure its high working performance under low-temperature conditions. In addition , The air-supplementing enthalpy-increasing compressor has the advantages of safety, reliability, energy saving and high efficiency. Therefore, the air-supplementing enthalpy-increasing compressor is widely used in air-conditioning products. [0003] The air supp...
