Problems solved by technology

[0002] The current compressors include single-stage compressors and two-stage compressors. Commonly used single-unit compressors can meet the energy efficiency requirements of refrigeration, while two-stage compressors have advantages in heating, but the power in cooling is relatively high, which exceeds the range of energy efficiency. There is an urgent need for a compressor that can directly convert between a single-stage compressor and a two-stage compressor, and has the functions of heating, enthalpy, and refrigeration.

Abstract

The invention discloses a grade variable compressor. The grade variable compressor comprises a motor stator, a rotor, a crankshaft, an upper roller, a lower roller, an upper flange, an upper cylinder, a separator plate, a lower cylinder and a lower flange. The upper roller and the lower roller are respectively installed on the crankshaft and rotate in the upper cylinder and the lower cylinder for working. The wall of the upper cylinder is provided with a slide plate groove. An upper slide plate capable of coordinating with the upper roller is installed in the slide plate groove. The upper flange is provided with a slide plate control device which can control the motion of the upper slide plate so that the upper cylinder of the grade variable compressor selectively participates in compression working.

Description

【Technical field】 [0001] The invention relates to the field of compressors, in particular to a variable-stage compressor. 【Background technique】 [0002] The current compressors include single-stage compressors and two-stage compressors. Commonly used single-unit compressors can meet the energy efficiency requirements of refrigeration, while two-stage compressors have advantages in heating, but the power in cooling is relatively high, which exceeds the range of energy efficiency. There is an urgent need for a compressor that can be directly converted between a single-stage compressor and a two-stage compressor, and has the functions of heating enthalpy and refrigeration. 【Content of invention】 [0003] The invention improves the heating capacity and high-temperature cooling capacity of the compressor, and can directly switch between a single-unit compressor and a two-stage compressor. Single-unit compression is used for rated cooling, and high-temperature cooling, rated he...
