Abstract

The invention discloses a compressor stepless energy adjusting device and adjusting method and a refrigerating system. Wherein the device comprises a primary compressing cavity of a compressor, a bypass pipeline which is communicated with an air suction pipeline of the compressor and a flow rate adjusting valve which is arranged on the bypass pipeline. According to the device, oil route arrangement does not need to be considered, the structure of a compressor body is simple, and the processing difficulty and cost are reduced. The air discharging amount of the compressor can be controlled in real time by the flow rate adjusting valve, response can be timely made according to the variation of the load of the refrigerating system to adjust the flow rate of bypass fluid, and the response is rapid. The air discharging amount of the compressor can be timely controlled by an electronic expansion valve, and energy adjustment similar to stepless energy adjustment can be achieved to perfectly fit all loading points within the range.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a stepless energy adjustment device for a stepless capacity adjustment compressor, an adjustment method and a refrigeration system using the adjustment method. Background technique [0002] Compressors typically adjust capacity in response to changes in actual load. For example, the capacity adjustment method of screw compressors generally uses plungers, slide valves, and frequency conversion motors for step-by-step adjustment. However, for small displacement screw compressors, the structural configuration of the plunger and the slide valve is relatively complicated, and is often limited by the small body space, so it is very difficult to design and process. The use of variable frequency motors for capacity adjustment will lead to a substantial increase in costs. In order to reduce the cost of the compressor, at the same time bring additional expenditure on frequency c...
