Condenser assembly and its control method, oil return assembly and air conditioner

Abstract

The application provides a condenser assembly, including: a condenser body and an oil return structure, the oil return structure includes a separation chamber and a drainage assembly; the separation chamber is arranged inside the condenser body; the separation chamber is used for mixing refrigerant and lubricating oil The liquid is separated; the drainage component is used to guide the mixture of refrigerant and lubricating oil into the separation chamber, and guide the separated oil to flow to the oil tank, and guide the separated refrigerant to flow back to the refrigeration system. According to the condenser assembly of the present application, the high-temperature gas in the condenser body is used to exchange heat with the mixture of oil and refrigerant in the separation chamber, so that the separation of lubricating oil and refrigerant is more thorough, and the refrigerant evaporates in the separation chamber without Reduce the temperature of the oil tank and affect the effect of lubricating oil.

Description

technical field [0001] The application belongs to the technical field of air conditioners, and in particular relates to a condenser assembly, a control method thereof, an oil return assembly and an air conditioner. Background technique [0002] At present, the compressor needs lubricating oil to lubricate the bearings during operation. At this time, the lubricating oil is in direct contact with the refrigerant, causing the lubricating oil to dissolve in the refrigerant and enter the evaporator with the refrigerant, which makes the heat transfer performance of the evaporator worse. The coefficient of performance of the system decreases. Moreover, the long-term operation of the compressor makes the lubricating oil continuously dissolve into the refrigerant, the oil level in the oil tank drops, and the compressor lacks the lubrication of the lubricating oil, so it will not be able to operate normally. Therefore, in the prior art, the mixture of oil and refrigerant in the evapo...

AI Technical Summary

Problems solved by technology

[0003] However, the temperature of the suction port of the compressor is low, the refrigerant cannot be completely evaporated, the lubricating oil and the refrigerant cannot be completely separated, and the mixture of oil and refrigerant is drawn into the oil tank, and the refrigerant evaporates and absorbs heat in the oil tank, resulting in a drop in the temperature of the oil tank, and the lubricating oil The lubricating effect becomes worse
