2, regeneration: the regeneration process is the recovery of the refrigerant back to the process of treatment. Recovery of refrigerant impurities in the main solid particles, refrigeration oil, water, air and other categories. This task is mainly completed by the filter drier. It removes the solid impurities and moisture in the recovered refrigerant. There is no oil separator inside the equipment to separate the refrigeration oil in the recovered refrigerant. Because air is a non-condensable gas. At the end of the recovery, you can press the emptying valve on the refrigerant tank to release the air in the tank, and the whole regeneration process ensures that the recovered refrigerant can be used again.
3, vacuum process: because the recovery of the air conditioning system can not reach the required vacuum, so the air conditioning system must be thoroughly vacuumed. This is also conducive to the removal of water and other gases remaining in the system. Ensure that the refrigerant refilled into the system is not contaminated, this process is equipped with large-capacity, imported two-stage vacuum pump to complete the process, pumping more thoroughly, and is conducive to the detection of air-conditioning system of small leaks.
4, refilling: air conditioning system maintenance needs to be re-injected into the system refrigerant, for small air conditioning, mainly relying on the refrigerant tank and the pumped system between the pressure difference between the refrigerant into the system. For large air conditioners, our company has designed a pressure charging function for the recovery charging equipment, which relies on the compressor inside the equipment to realize the transfer of refrigerant into the system. Relying on the precise electronic metering system to realize the automatic quantitative charging of refrigerant.
The equipment has the above four functions, which can effectively save the maintenance cost of automobile repair enterprises, and has significant social and environmental significance.
