It is reported that the new national standard combines the energy efficiency of the original fixed frequency and inverter air conditioners, and the energy efficiency level has also been expanded from the original 3 to 5. Industry experts said that after the standard upgrade, the energy efficiency in... read more
The refrigerant is the heat transfer carrier in the refrigeration cycle. It absorbs and releases heat through state changes. Therefore, it is required that the refrigerant is easy to vaporize at room temperature and easy to liquefy after pressurization. R134 refrigerant tube At the same time, it sho... read more
1. Refrigerant R134a: R134a (tetrafluoroethane) is not good for refrigeration systems because of its high water solubility. Even if there is a small amount of water, it will produce acid, carbon dioxide or carbon monoxide under the action of lubricating oil, which will cause corrosion to meta... read more
1. Too much refrigerant causes insufficient refrigeration. Maintenance method: Observe bai from the sight glass above the drying tank. If the car air conditioner does not see any bubbles in the sight glass during operation, and there are no bubbles even after the compressor stops, R134 refrig... read more
Refrigerants are also called refrigeration working fluids, commonly known as refrigerants in some areas in the south. It is a working substance that continuously circulates in the refrigeration system and realizes refrigeration through its own state changes. R410 refrigerant tube The refrigerant ab... read more
