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 refrigeration device. It uses a single R32 refrigerant or a mixed refrigerant containing more than a specified mass percentage of the R32 refrigerant as the refrigerant. The gas refrigerant inlet pipe at the bottom of the liquid accumulator of the compressor is provided with a liquid refrigerant inlet pipe leading to the air inlet of the cylinder, and the liquid refrigerant inlet pipe is not in direct contact with the metal wall on the air inlet passage of the cylinder; An insulating structure is arranged on the suction chamber side of the compression assembly, and an insulating pipe is arranged on the tapered pipe in the refrigerant inlet pipe assembly. The compressor and refrigerating device satisfying the characteristics of the present invention reduce ineffective overheating during the suction process, effectively control the dryness during the suction process, thereby reducing the exhaust temperature and improving the reliability of the compressor and the energy efficiency of system operation.

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 rotor compressor is a fluid machine that lifts low-temperature and low-pressure refrigerant into high-temperature and high-pressure refrigerant gas. When the rotor compressor is working, the low-temperature and low-pressure refrigerant is sucked from the suction pipe, and the rotor is driven by the motor to compress it, and finally the high-temperature and high-pressure refrigerant gas is discharged from the exhaust pipe. Through the above working process, the whole system realizes the refrigeration cycle of compression-condensation (exothermic)-expansion-evaporation (endothermic). [0003] The pump body structure of the existing rotary compressor includes a cylinder, an upper flange and rollers, a sliding vane, a crankshaft and a lower flange. When the compressor is w...
