Problems solved by technology

[0003] At present, most of the multifunctional refrigerant recovery machines on the market have the functions of refrigerant recovery, refrigeration system vacuuming and charging, but seldom consider the recovery and charging of refrigeration oil, and it is easy for the refrigeration system to recover refrigerant several times. Due to repeated vacuuming, the compressor is short of oil, which accelerates the wear of the compressor until it is damaged; in addition, when charging the system refrigerant, most manufacturers use the pressure gauge to judge the charging amount, which will also cause the actual operation of the refrigeration system. In the middle, the low efficiency operation of the system is caused by the deviation of the amount of refrigerant

Abstract

The invention discloses an automatic recovery and fill system of a refrigeration system, comprising a refrigerant recovery and fill device, a vacuum extractor and a refrigeration oil recovery and fill device, wherein, the refrigerant recovery and fill device comprises a gas-liquid separation evaporating drum, a compressor, an oil separator, a condenser and a fluid reservoir; the refrigeration oil recovery and fill device comprises an oilway filter, an oil reservoir and an oil flowmeter. As an outlet of the oil separator of the system additionally has the refrigeration oil recovery and fill device, both refrigerant recovery and refrigeration oil recovery are realized, also, the refrigeration oil can be filled into the refrigeration system and the compressor. The gas-liquid separation evaporating drum of the invention can separate gas and liquid fully, while a heating strip under the drum enables liquid refrigerant in the drum to evaporate at every moment, which prevents the return liquid damaging the compressor. The system has the effects of energy saving and environmental protection.

Description

technical field [0001] The invention relates to a recovery and reuse device for a refrigeration system, in particular to an automatic recovery and charging system for a refrigeration system. Background technique [0002] In order to promote the sustainable development of the environment and improve the living conditions of human beings, countries all over the world have restricted the discharge of HCF and HCFC refrigerants to the atmosphere. At the same time, because some environmentally friendly refrigerants are expensive, it is an economical and environmentally friendly method to collect refrigerants in waste refrigeration systems or experimental development and testing systems for recycling. [0003] At present, most of the multifunctional refrigerant recovery machines on the market have the functions of refrigerant recovery, refrigeration system vacuuming and charging, but seldom consider the recovery and charging of refrigeration oil, and it is easy for the refrigeratio...
