Embodiment Construction

[0020] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0021] The working principle of the cabinet type air conditioner of the present invention is the same as the prior art, and the prior art can be referred to, so it will not be described again. The difference between the present invention and the prior art is that the structure of the copper tube of the supercooler is different, and the following is carried out For detailed description, the same parts as those of the prior art use the symbols of the prior art, and refer to the drawings of the prior art.

[0022] like figure 1 As shown, the outdoor unit 1 of the air conditioner of the present invention includes: a rectangular hexahedron casing 10 with an opening structure formed inside to form an accommodation space; The separator 20; several compressors 30 for compressing the refrigerant flowing in from the gas-liquid separator 20; and the outdo...

Abstract

The invention discloses a copper tube structure of a subcooler for an air conditioner outdoor unit. The air conditioner outdoor unit comprises an enclosure with an accommodating space formed inside, a common gas-liquid separator, a plurality of compressors, an outdoor heat exchanger and the subcooler, wherein the common gas-liquid separator is arranged inside the enclosure and is used for performing gas-liquid separation on a refrigerant; the compressors are used for compressing the refrigerant flowing from the gas-liquid separator; the outdoor heat exchanger is arranged in an opening area of the enclosure so as to subject the inside refrigerant to heat exchange; and the subcooler is arranged between the outdoor heat exchanger and the compressors and is made of a copper tube, the cooper tube is of a dual-layer casing pipe structure composed of an inner tube and an outer tube, the inner tube is a threaded tube, and the outer tube is a common round tube. According to the invention, the subcooling performance of a system can be effectively increased, the noises can be reduced and the system performance can be improved.

Description

technical field [0001] The invention relates to an outdoor unit for an air conditioner, in particular to a copper tube structure for a subcooler of an outdoor unit for an air conditioner. Background technique [0002] Generally, air conditioners are divided into integral air conditioners in which an outdoor unit and an indoor unit are arranged in one casing, and a compressor and a condenser are arranged in a casing outdoors as an outdoor unit, and an evaporator is arranged indoors as an air conditioner. Split air conditioner with indoor unit. [0003] Recently, since the market has increasingly higher requirements for the cooling capacity of split-type air conditioners, in large-scale air conditioners, several compressors are equipped on the outdoor unit to effectively meet various cooling requirements. [0004] like figure 1 As shown, the outdoor unit 1 of the air conditioner in the prior art includes: a rectangular hexahedron casing 10 with an opening structure formed on...
