An oil separator and refrigeration equipment using the oil separator

Abstract

The invention discloses an oil separator for refrigeration equipment. The oil separator comprises a sealing cavity defined by an upper end cover, a lower end cover and a barrel. The upper end cover is communicated with an outlet of a compressor of a refrigerating system through an air inlet pipe, and the sealing cavity is communicated with an inlet of a heat exchanger of the refrigeration equipment through an air outlet pipe. The oil separator is further provided with an oil eliminating device which is used for separating refrigerant steam and lubricating oil of a mixture input by the air inlet pipe, and the oil eliminating device is arranged between the air inlet pipe and the air outlet pipe. The oil separator of the structure enables mixed gas to be separated into the refrigerant steam and liquid lubricating oil, so that liquid oil drops and oil steam in the mixture are separated completely, oil separating effect is greatly improved, and therefore the heat exchange effect of the heat exchanger is improved. In addition, the oil separator of the structure further has the advantages of being simple in structure and low in cost. The invention further provides the refrigeration equipment including the oil separator.

Description

technical field [0001] The invention relates to refrigeration equipment, in particular to an oil separator for refrigeration equipment. In addition, the present invention also relates to a refrigeration device comprising the above-mentioned oil separator. Background technique [0002] In refrigeration equipment, when the compressor outputs high-pressure refrigerant vapor to the heat exchanger, it also outputs part of the lubricating oil inside, and if the lubricating oil enters the heat exchanger, it will affect the heat transfer effect of the heat exchanger. Adverse effects, therefore, it is necessary to install an oil separator between the compressor and the heat exchanger to separate the refrigerant vapor and lubricating oil, so that the refrigerant enters the heat exchanger in an "oil-free" state, improving the condenser and evaporation The effect of heat transfer in the vessel. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of an o...

AI Technical Summary

Problems solved by technology

[0007] First of all, the oil separation effect of the oil separator is not complete, and the residual oil droplets flowing out of the air intake pipe may drip into the air outlet pipe, and then enter the air conditioning system, affecting the cooling effect of the refrigeration system;

[0008] Secondly, the oil separator has a good separation effect between the refrigerant vapor and the liquid lubricating oil, but for the oil vapor, the separation effect is not achieved, and the oil vapor will still enter the heat exchanger through the outlet pipe together with the refrigerant vapor. Affect the heat transfer effect of the heat exchanger
