Abstract

The invention provides a condenser assembly which comprises a condenser body and an oil return structure, and the oil return structure comprises a separation chamber and a drainage assembly; the separation chamber is arranged in the condenser body; the separation chamber is used for separating a mixed solution of a refrigerant and lubricating oil; the drainage assembly is used for guiding mixed solution of the refrigerant and the lubricating oil to enter the separation chamber, guiding separated oil to flow to the oil tank and guiding the separated refrigerant to flow back to the refrigeratingsystem. According to the condenser assembly, heat exchange is conducted between the high-temperature gas in the condenser body and mixed solution of the refrigerant and the lubricating oil in the separation chamber, so that lubricating oil and the refrigerant are separated more thoroughly, the refrigerant is evaporated in the separation chamber, the temperature of the oil tank cannot be reduced,and the lubricating oil effect cannot be affected.

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...
