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, and aims at solving the problem about disturbance of an air supplementing pipeline due to the high flow speed of a refrigerant in the air supplementing pipeline and the problem about service life shortening due to compressor liquid return. For the purpose, the outdoor unit comprises a pressure container arranged on the air supplementing pipeline, the pressure container comprises a container body, and at least one cavity with the diameter larger than the diameter of the air supplementing pipeline is formed by the container body, so that the flow speed of the refrigerant is reduced; and the pressure container has the gas-liquid separation function, and accordinglythe refrigerant flowing out of a refrigerant outlet is a gas-state refrigerant. Through the pressure container, the flow speed of the refrigerant in the air supplementing pipeline is reduced, the refrigerant enters a compressor through an air supplementing enthalpy increasing connector in the gas state form, vibration of the air supplementing pipeline can be reduced, compressor liquid return is avoided, and the service life of the compressor is prolonged.

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...
