Abstract

The invention discloses a compressor as well as a cooling-heating refrigeration device equipped with the same and a cooling-only refrigeration device equipped with the same. The compressor comprises a shell, a first air cylinder and a second air cylinder, wherein an air exhaust pipe, a first air suction pipe and a second air suction pipe are arranged on the shell; a first air exhaust channel and a first air suction channel communicating with the first air exhaust pipe are arranged on the first air cylinder; the air suction volume of the first air cylinder is set to V1; the minimum flow area of the first air suction channel is set to S1; a second air exhaust channel and a second air suction channel communicating with the second air exhaust pipe are arranged on the second air cylinder; the air suction volume of the second air cylinder is set to V2; the minimum flow area of the second air suction channel is set to S2; the air suction pressure of the second air cylinder is higher than that of the first air cylinder; and the first air cylinder and the second air cylinder meet the following relation: the product of 1.2 and V2 over V1 is smaller than or equal to S2 over S1. According to the compressor disclosed by the invention, the air suction pressure loss of the second air cylinder is reduced, and the relatively high compressed air indication efficiency is guaranteed.

Description

technical field [0001] The invention relates to the field of refrigeration, in particular to a compressor, a heating and cooling refrigeration device, and a cooling-only refrigeration device provided with the compressor. Background technique [0002] At present, the heating technology of the air conditioner, especially in the low outside temperature, the heating capacity will be greatly attenuated, and the heat demand of the user cannot be met. In addition, with the implementation of APF energy efficiency of air conditioners, the lack of low-temperature heating capacity of air conditioners has become increasingly prominent, and solutions need to be sought. [0003] In order to solve this problem, in recent years, the application of gas refrigerant injection method to compressors and refrigeration equipment has attracted much attention, especially the research on the use of twin-cylinder rotary compressors has made progress. Contents of the invention [0004] The present i...
