Turbine compressor

Abstract

A turbine compressor comprises an enclosed container, an immobile scroll pan and a mobile scroll pan; wherein, the immobile scroll pan is fixedly arranged inside of the enclosed container, and spiralimmobile scroll teeth are formed on the immobile scroll pan; wherein, the immobile scroll pan is fixedly arranged inside of the enclosed container, and spiral mobile scroll teeth are formed on the mobile scroll pan, the mobile scroll teeth are engaged with the immobile scroll teeth, a pair of compression cavities can be formed when the immobile scroll pan and the mobile scroll pan rotate relatively; at least one bypass hole communicating an inner side and an outer side of the compression cavity is formed on the immobile scroll pan, and a middle compression cavity is formed at an outlet side ofthe bypass hole. according to the turbine compressor of the invention, a plurality of bypass holes capable of bypassing one part of the refrigerant compressed by the compression cavity are formed onthe immobile scroll pan, and a middle compression cavity for mutually communicating outlet ends of the bypass holes is formed on a top surface of a base board of the immobile scroll pan, meanwhile, abypass valve is arranged at the outlet of the middle compression cavity, thereby simplifying the device for adjusting the power, implementing the miniaturization of the compressor and reducing the producing cost.

Description

technical field [0001] The invention relates to a turbo compressor capable of accurately adjusting power. Background technique [0002] Generally, a turbo compressor is a high-efficiency, low-noise compressor widely used in the field of air conditioning. The above-mentioned turbo compressor usually has two scrolls that rotate relative to each other, thereby forming a pair of compression chambers. The volume of the compression chamber gradually becomes smaller as it continues to move toward the center, so that the refrigerant is continuously sucked in, and then the refrigerant is compressed and discharged. In addition, a plurality of bypass holes are formed in the middle of the compression chamber on the above-mentioned turbo compressor, which can be used to make a part of the refrigerant in the intermediate pressure state flow to the side of the suction groove, so as to change the power of the compressor, or to discharge The pipe is connected with the suction pipe, and a s...

AI Technical Summary

Problems solved by technology

However, the above-mentioned prior art turbocompressor has the following problem: for the above-mentioned turbocompressor provided with bypass holes, since the positions of the multiple bypass holes are formed symmetrically with the discharge port as the center, in order to open and close the above-mentioned These bypass holes need to set multiple valves, which will increase the production cost, and need to control multiple bypass holes at a long distance, so the reliability of the compressor may be reduced

In addition, the amount of refrigerant delivered by each bypass hole is uneven, so the power of the compressor cannot be adjusted accurately

On the other hand, for the above-mentioned turbo compressor in which the suction pipe and the discharge pipe are connected, since the piping arrangement is complicated and valves are installed on the piping, the structure of the compressor becomes larger and the number of assembly steps increases, resulting in an increase in cost.
