Capacitance-variable control structure, compressor and capacitance-variable control method thereof

Abstract

The invention discloses a capacitance-variable control structure, a compressor and a capacitance-variable control method thereof. The structure comprises a capacitance-variable assembly and a slidingvane restraint unit (8), wherein the capacitance-variable assembly is arranged on the outer part of a shell (1) of the compressor to which the capacitance-variable control structure belongs, and is used for acting according to a setting sequence; and the sliding vane restraint unit (8) is arranged in a pump body of the compressor, and is used for enabling a capacitance-variable cylinder assembly in the compressor to be at a working state or an idling state under the control of acting of the capacitance-variable assembly according to the setting sequence. According to the technical scheme provided by the invention, the defects such as violent shaking, easiness in machine halt and easiness in breaking a pipeline in the prior art can be overcome, and the beneficial effects on reducing shaking, preventing machine halt, and preventing the pipeline from being broken are achieved.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to a variable capacity control structure, a compressor and a variable capacity control method thereof, in particular to a variable capacity control structure of a rolling rotor type variable capacity compressor, and a device with the variable capacity control structure A compressor, and a variable displacement control method of the compressor. Background technique [0002] The rotary compressor is driven by an engine or an electric motor (mostly driven by an electric motor), and the other rotor (also known as a female rotor or a concave rotor) is driven by the oil film formed by the main rotor through oil injection, or by the main rotor end and the female rotor. Synchronous gear drive at the end. The air-conditioning system using the rolling rotor compressor generally adopts frequency conversion technology to control the compressor speed to adjust the cooling and he...
