Household air conditioner with centrifugal compressor assembly

Abstract

The invention relates to the technical field of household air conditioners, in particular to a household air conditioner with a centrifugal compressor assembly. The household air conditioner comprisesa machine case. The centrifugal compressor assembly is arranged in the machine case. The centrifugal compressor assembly comprises two shells. Each shell is internally provided with a centrifugal compressor groove, a gas-liquid separator groove, a liquid storage tank groove, an expansion valve groove, a dryer groove and a one-way valve groove, and the above grooves are formed in the shell througha CNC machining center. The centrifugal compressor assembly achieves the effect of the extremely high energy efficiency through arrangement of a centrifugal compressor, and the cop can reach up to 7.0 or more. Meanwhile, the centrifugal compressor assembly integrates a great number of parts of an existing air conditioner, and the parts are integrated into one assembly; modularization of the compressor is realized. The energy efficiency ratio of the household air conditioner is increased finally, and the installation size of an air conditioner host machine is effectively reduced. Industrial automatic production of air conditioners, personalized customization of users, free collocation of the functions and full intelligent application of the air conditioner can be realized.

Description

technical field [0001] The invention relates to the technical field of household air conditioners, in particular to a household air conditioner with a centrifugal compressor assembly. Background technique [0002] At present, non-centrifugal refrigeration compressors are used in existing household air conditioners to connect four-way valves, liquid storage tanks, dryers, expansion valves, compressors, gas-liquid separators, condensers, and evaporators through copper pipes. . [0003] The home air-conditioning main unit adopting the above-mentioned connection method is affected by the interconnection of various components, resulting in relatively large size of the air-conditioning main unit and requiring a large installation space. [0004] At the same time, since the connection between parts requires manual assembly or welding, it is not conducive to the industrial automation and integrated production of air conditioners. [0005] At the same time, the existing household a...

Problems solved by technology

[0003] The main unit of the household air conditioner using the above connection method is affected by the interconnection of various components, resulting in a relatively large size of the main unit of the air conditioner, which requires a large installation space

[0004] At the same time, because the connection between parts requires manual assembly or welding, it is not conducive to the industrial automation and integrated production of air conditioners

[0005] At the same time, the existing household air-conditioning hosts all use non-centrifugal refrigeration compressors for refrigeration, and their energy efficiency ratio COP is usually below 3.0. Intelligent Application of Air Conditioning
