In order to ensure the effect and prolong the life of the refrigeration equipment, it is necessary to ensure that there is no non-condensable gas in the refrigeration system, and the refrigeration system must be vacuumed.
The outdoor unit of the air conditioner needs to be charged with a sufficient amount of refrigerant before leaving the factory, so the outdoor unit needs to be vacuumed before charging.
The common oil-sealed rotary vane vacuum pump has a belt drive and a direct connection structure, that is, the drive motor and the pump body are directly connected by flange, and the pump and motor shaft are connected by an elastic coupling.
The presence of moisture and non-condensable gas affects the operation effect of the air conditioner, so the purpose of vacuuming is to remove the non-condensable gas and moisture in the air conditioner system.
Vacuuming is a necessary means to eliminate potential failures of the air-conditioning system. The quality of the vacuum operation directly affects the cooling and heating effect of the air conditioner.
For air conditioners, vacuuming is an indispensable and important process before refrigerant charging during the production, installation and maintenance of air conditioners.
Air leakage causes: There are problems in the pumping system itself. There is gas or gas leakage inside the system or container. The system is leaking.
