Compressor and air suction silencer thereof

Abstract

The invention discloses a compressor, belongs to the technical field of refrigeration equipment, and solves the technical problem that in the prior art, direct heat conduction contact between a refrigerant outlet end of an air suction silencer and a compression air cylinder leads to a high temperature of the refrigerant outlet, and as a result, the refrigeration performance of a compressor is nothigh. The compressor comprises a shell, a compression air cylinder, a piston, a driving mechanism and an air suction silencer, wherein a connecting part comprises a joint surface and a refrigerant outlet, the joint surface is used for being combined with an air cylinder cover, the connecting part is provided with at least one heat insulation cavity, and the heat insulation cavities are located onthe periphery of the refrigerant outlet and isolate the refrigerant outlet from the joint surface. Due to the fact that the heat insulation cavities isolate the joint surface for combination of the connecting part and the air cylinder cover from the refrigerant outlet, the heat insulation cavities can obstruct the heat transfer between the refrigerant outlet of the silencer and the air cylinder cover, the temperature of refrigerants entering from the refrigerant outlet to the compression air cylinder can be effectively reduced, the gas transmission coefficient of the compressor is improved, and the coefficient of performance of the compressor is increased.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a compressor and a suction muffler thereof. Background technique [0002] In the prior art, for the compressor, when the temperature of the refrigerant coming out of the suction muffler is low, the gas transmission coefficient of the compressor can be increased, thereby improving the energy efficiency ratio (COP) of the compressor. However, when the compressor is working , the mechanical energy is converted into heat energy, the temperature of the compressed cylinder is high, because the suction muffler is in direct heat conduction contact with the compressed cylinder, the heat of the compressed cylinder is transferred to the suction muffler through heat conduction, so the temperature of the refrigerant coming out of the suction muffler is relatively high , so that the performance of the compressor is low and the cooling effect is not good. [0003] The Chinese i...
