Problems solved by technology

[0014] However, the capacity variable device of the existing scroll compressor not only discharges an appropriate amount of refrigerant according to the characteristics of the scroll compressor with a predetermined volume, but also discharges the refrigerant according to the pressure when the capacity is low. Therefore, the pressure of the discharged refrigerant decreases, which eventually leads to a decrease in the efficiency of the compressor due to insufficient compression, and at the same time, the operating time of the air conditioner is prolonged, and the power loss increases.

Abstract

A volume variable vortex compressor is composed of casing, motor, machine frame in said casing for supporting the rotary axle of motor and with vortex volute, movable vortex disc on said machine frame, eccentrically connected to the rotary axle of motor and with the first vortex volute on its lower surface to form the first compression chamber and the second vortex volute on its upper surface to form the second compression chamber, the fixed vortex disc for matching with the movable one to form the second compression chamber, and connection unit for regulating the flow channel of cold medium for sequential or alternative compression of said two compression chamber.

Description

technical field [0001] The present invention relates to a scroll compressor. In particular, it relates to a capacity-variable scroll compressor capable of improving compression efficiency during low-capacity operation. Background technique [0002] Generally speaking, the scroll compressor is: multiple scrolls move relative to each other, so that the space of the compression chamber changes continuously to inhale, compress and discharge refrigerant. Compared with other types of compressors, scroll compressors are small in size, high in efficiency and excellent in performance, so they are widely used in air conditioners such as air conditioners. [0003] Recently, with the diversification of air-conditioning functions, scroll compressors are also required to be able to change the capacity. The existing way to change the capacity of the compressor is to change the capacity of the compressor through the number of revolutions of the compressor, but the machine using this metho...
