Problems solved by technology

Such a result will increase the ineffective overheating of the suction, which will increase the temperature of the exhaust gas. When the external environment temperature is low, such as heating, etc., the temperature of the compressor will rise and exceed the heat-resistant temperature of the motor insulation material, resulting in reliable performance and energy efficiency issues

Abstract

The invention discloses a compressor and a refrigerating device. The compressor adopts an independent R32 refrigerant or a hybrid type refrigerant containing the R32 refrigerant of specified mass percentage or more. A liquid refrigerant inlet tube which extends to a gas suction hole of a gas cylinder is arranged in a gas refrigerant inlet tube on the bottom of a liquid accumulator of the compressor; the liquid refrigerant inlet tube is not in direct contact with a metal wall surface on a gas cylinder gas inlet channel; a gas suction cavity side of a compression assembly of the compressor is provided with a heat insulating structure; and a tapered tube in the refrigerant inlet tube assembly is provided with a heat insulating tube. The compressor and the refrigerating device, which meet characteristics of the invention, reduce ineffective overheat in a gas suction process, and effectively control dryness in a gas suction process, so that a gas exhaust temperature can be reduced, reliability of the compressor is improved, and energy efficiency of system operation is improved.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a compressor and a refrigeration device. Background technique [0002] As the heart of the refrigeration system, the rotary compressor is a fluid machine that upgrades low-temperature and low-pressure refrigerant to high-temperature and high-pressure refrigerant gas. When the rotary compressor is working, it sucks low-temperature and low-pressure refrigerant from the suction pipe, uses the motor to drive the rotor to compress it, and finally discharges high-temperature and high-pressure refrigerant gas from the exhaust pipe. Through the above working process, the entire system realizes a refrigeration cycle of compression-condensation (heat release)-expansion-evaporation (heat absorption). [0003] The pump body structure of the existing rotary compressor includes a cylinder, an upper flange and a roller, a sliding vane, a crankshaft and a lower flange. When the compressor is working...
