Compressor and heat pump system

Abstract

The invention provides a compressor and a heat pump system. The scroll compressor comprises a shell body and a static vortex disc arranged in the shell body, and the static vortex disc separates a high-temperature exhaust cavity in the shell body; and the scroll compressor further comprises an air suction heat insulation pipe for communicating with an air suction port and an air suction pipe on the static vortex disc, wherein the air suction heat insulation pipe comprises a communicating pipe and a heat insulation pipe, the first end of the communicating pipe is used for communicating with theair suction pipe, and the second end of the communicating pipe is used for communicating with the air suction port; the heat insulation pipe sleeves on the outer side of the communicating pipe, a heat insulation cavity is formed between the heat insulation pipe and the communicating pipe, and the heat insulation pipe is located in the high-temperature exhaust cavity and used for separating the communicating pipe and the high-temperature exhaust cavity. According to the compressor, a low-temperature refrigerant sucked by the compressor is prevented from being heated by the high-temperature exhaust gas, so that the air suction volume efficiency loss caused by air suction thermal expansion is reduced, and the compressor efficiency is guaranteed.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor and a heat pump system. Background technique [0002] The scroll compressor has the advantages of simple structure, small size, light weight, low noise, high mechanical efficiency and stable operation. Among them, the high-pressure chamber scroll compressor adopts a direct suction structure, and the suction steel pipe is directly inserted into the suction port of the static disk. Because the suction steel pipe needs to go through high-temperature exhaust during the process from the upper cover to the static disk, resulting in pre-suction When heated, the suction produces thermal expansion, which leads to a decrease in the suction volumetric efficiency, which affects the efficiency of the compressor. [0003] Therefore, it is necessary to reduce the preheating of the suction to avoid the expansion of the refrigerant before entering the compressor, so as to improv...
