Abstract

The invention provides a refrigerant recycling and charging device. The refrigerant recycling and charging device comprises input pipe fittings, an evaporator, a first oil-gas separator, a compressor, a second oil-gas separator, a condenser and output pipe fittings, which are sequentially communicated, wherein a second oil discharging pipeline of the second oil-gas separator is communicated with a pipeline between the compressor and the first oil-gas separator. According to the design of the refrigerant recycling and charging device, the first oil-gas separator separates refrigeration oil in the refrigerant first, so that the situation that the refrigeration oil enters the compressor to cause damage to the compressor is effectively prevented. The second oil-gas separator separates compressor lubricating oil in the refrigerant flowing from the compressor, so that pollution to the refrigerant is prevented. Besides, the oil discharging pipeline of the second oil-gas separator leads the compressor lubricating oil in the entry end of the compressor, so that the compressor lubricating oil can be recycled, and the service efficiency is improved.

Description

technical field [0001] The invention relates to the field of refrigerant charging and discharging devices, in particular to a refrigerant recovery and charging device. Background technique [0002] In the refrigeration (or heating) system, the refrigerant plays a pivotal role as the carrier of heat transfer. In the process of manufacturing, testing and verification of the refrigeration system, it is inevitable to encounter the problems of refrigerant discharge and charging. With the strengthening of people's awareness of environmental protection, the price of refrigerants continues to rise, and countries all over the world have restricted the discharge of HCF and HCFC refrigerants to the atmosphere. Refrigerant recovery has become increasingly popular. The device integrating the functions of refrigerant recovery and charging has increasingly become a necessary equipment in the maintenance of refrigeration equipment. [0003] The invention patent of CN201628430U authorized...
