Abstract

The invention relates to a refrigerating system with a capacity-adjusting scroll compressor. The invention adjusts the fit between the compressor and the operating condition through the leakage of a refrigerant of the compression middle section of the compressor to the low pressure side and the injection of the refrigerant of the high pressure side to the compression middle section of the compressor, which can effectively change the efficiency of the compressor and the capacity and performance of the system to result in that the refrigerating system with the scroll compressor can efficiently works within the large range of operating conditions and can effectively adjust the capacity of the system to make the capacity inosculated with the changeable refrigerating or heating requirements in order to improve the applicability of the system and the energy efficiency of the system under varied operating conditions of the large range. The invention can be used in the refrigerating or heating pump system with the scroll compressor in the air conditioning refrigerating field.

Description

technical field [0001] The present invention relates to a refrigerating system containing a scroll compressor, more specifically, to a system form and a control method for changing the capacity and performance of the refrigerating system containing a scroll compressor through leakage or / and injection of refrigerant. Background technique [0002] A scroll compressor is a type of compressor used in refrigeration and air conditioning. Due to the advantages of high efficiency and low noise, scroll compressors are widely used in small and medium capacity refrigeration and air conditioning systems. The scroll compressor has a pair of symmetrically arranged scroll disks, that is, a static disk and a moving disk. The static disk is fixed on the body of the compressor, and the moving disk performs circular translation around the static disk within a certain range. At the initial stage of compression, the low-pressure refrigerant gas is drawn into the compression cavity by the outer ...
