A kind of refrigeration compression equipment capable of separating oil and gas

Abstract

The invention relates to the technical field of compressors and relates to a refrigeration compression device capable of oil-gas separation. The device comprises a compressor and an oil-gas separationdevice disposed at a gas output of the compressor, wherein the oil-gas separation device comprises a horizontally disposed box body, a gas inlet pipe disposed on one end of the box body, a gas outputpipe disposed on the other end of the box body, separation frames which are disposed in the box body at intervals along the width direction of the box body, separation plates which are disposed in the separation frames at intervals along the length direction of the box body, as well as an oil return pipe disposed on the bottom of the box body; and one end, remote from the box body, of the oil return pipe is communicated with interior of the compressor. The device provided by the invention has the beneficial effects that a refrigerating medium passes through the separation plates during motion, so oil liquid can be adhered on the separation plates; the separated refrigerating medium can finally enter a condenser via the gas output pipe on the other end of the box body; and the oil liquid which keeps accumulating on the separation plates can finally drip down and flow back into the compressor via the oil return pipe, so oil-gas separation effects are enhanced.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to refrigeration and compression equipment capable of separating oil and gas. Background technique [0002] In a refrigeration system, oil and refrigerant are mixed together to lubricate and cool the compressor, so the oil and refrigerant flow together into the compressor. Then, as the high-pressure refrigerant is discharged, some oil is discharged together with the refrigerant, continuously circulating through the condenser, capillary and evaporator. As the amount of oil participating in the refrigerant cycle increases, the amount of refrigerant becomes smaller, and the performance of the air conditioner decreases. When the discharged oil does not return to the compressor, or the return time is too late, the compressor will be short of oil, causing the compressor to malfunction.

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: if the compressor uses this kind of oil separator, since the oil mixed in the refrigerant is often in the form of oil mist, and the diameter of the oil droplets is small, simply When the oil mist is separated by its own weight, some oil will be discharged together with the refrigerant, and the oil-gas separation effect is poor.
