Abstract

The present invention provides a compressor. The compressor includes a shell, a first-stage compression cylinder and a second-stage compression cylinder arranged in the shell. The gas compressed by the first-stage compression cylinder enters the second-stage compression cylinder for recompression. The second-stage compression cylinder has a high-pressure exhaust port. The machine also includes: an enthalpy-increasing channel, which is arranged in the upper flange, and a first control valve is arranged in the enthalpy-increasing channel, and the first control valve controls the connection or disconnection between the enthalpy-increasing channel and the high-pressure exhaust port. The volumetric efficiency of the two-stage compression cylinder can be effectively improved through the enthalpy-increasing channel.

Description

technical field [0001] The present invention relates to air conditioning equipment, in particular, to a compressor. Background technique [0002] Due to the many advantages of household central air-conditioning, the increase in its demand has shown a steady growth trend. It can be predicted that with the improvement of living standards, the increase of various high-quality residential quarters and the increase of renovation and expansion projects of office space, household central air conditioners will become a new consumption hotspot in the air conditioner market. Among them, the multi-unit market is the most promising. According to industry online statistics, the market capacity of this part of light commercial air conditioners reached 15.3 billion yuan in 2010, a year-on-year increase of 27%, and the market is in a period of rapid growth. In 2011, the annual market capacity exceeded 19 billion yuan. [0003] Household central air conditioners cater to the needs of domes...
