Embodiment Construction

[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0027] The invention provides a screw compressor. In its implementation, such as figure 2 and image 3 As shown, the screw compressor includes a body 10 on which an air supply channel is provided, and the air supply channel has a plurality of axial air supply holes 201 for communicating with the compression chamber.

[0028] In this embodiment, the number of axial air supply holes 201 that the air supply channel is used to communicate with the compression cavity is multiple, so that in the case of limited space on the machine body for...

Abstract

The invention provides a screw compressor, an air conditioning device and a refrigeration device. The screw compressor comprises a compressor body, and an air supply channel is formed in the compressor body and provided with at least two axial air supply holes for communicating with a compression cavity. According to the screw compressor provided by the invention, the air supply channel of the screw compressor is provided with the at least two axial air supply holes for communicating with the compression cavity, and thus, the diameter of each axial air supply hole is small under the condition that the space, for being provided with the axial air supply holes, of the compressor body is limited; and in the air supply process, compared with axial air supply holes large in diameter in the prior art, airflow pulsation of the axial air supply holes which are large in number and small in diameter in the screw compressor provided by the invention is decreased advantageously, and accordingly, noise in the air supply process is lowered.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a screw compressor, an air conditioner using the screw compressor, and a refrigeration device using the screw compressor. Background technique [0002] A screw compressor usually includes a body and a pair of parallel and intermeshed female and male screws arranged in the body. An air inlet is provided on the body corresponding to one end of the female and male screws, and an exhaust port is provided on the body corresponding to the other end. mouth. The above-mentioned screw compressor compresses the low-temperature and low-pressure gas entering from the air inlet of the body into high-temperature and high-pressure gas through the female and male screws in opposite directions, and discharges it from the air outlet of the body. [0003] The body of the existing screw compressor is usually provided with an air supply channel, which is used to supply gas to the compression cav...
