Refrigerating unit, oil supplying system and oil separator of oil supplying system

Abstract

The invention provides an oil separator. The oil separator comprises a hollow shell, spiral separation channels and first filtering assemblies, wherein the spiral separation channels are used for separating mixtures and are arranged in the shell; the first filtering assemblies are used for filtering and are arranged on the outer walls of the spiral separation channels, and the spiral separation channels communicate with the shell through the first filtering assemblies. The mixtures containing refrigerants and lubricating oil are separated through the spiral separation channels by means of centrifugal action, the problem that at present the occupied space of a refrigerating system is increased due to the fact that the oil return amount is increased through increase of the size of an oil separator is effectively solved, and the oil separation path is increased while the oil separation effect is guaranteed, so that oil return efficiency is improved; meanwhile, the structure size of the oil separator can be compact, and the occupied space of a refrigerating unit is reduced. The invention further provides the refrigerating unit and an oil supplying system thereof.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigeration unit, an oil supply system and an oil separator thereof. Background technique [0002] In the refrigeration system, in order to protect the normal operation of the compressor, it is necessary to add lubricating oil to the refrigerant. However, with the refrigeration cycle of the refrigeration system, the lubricating oil will be distributed throughout the refrigeration system. In order to ensure sufficient oil content in the compressor, it is necessary to add oil to the refrigeration system or add a system with oil return function. The oil separation efficiency of the current oil separator is low, especially for a refrigeration system with a large number of horses, it is often necessary to select a larger volume of oil to increase the oil return, but this will increase the occupied space of the refrigeration system. Therefore, how to reduce the vol...

AI Technical Summary

Problems solved by technology

[0003] Based on this, it is necessary to address the current problem of increasing the space occupied by the refrigeration system by increasing the size of the oil separator to increase the amount of oil returned, and to provide a system that can ensure the oil return while ensuring a compact structure and reducing the space occupied by the refrigeration unit. An oil separator, and also provide an oil supply system containing the above oil separator, and a refrigerating unit containing the above oil supply system
