R-410A refrigerant ratio is constant, used in commercial air-conditioning

With the signing of the Montreal Agreement in 1987, CFC refrigerants (such as R-11, R-12, etc.) have been completely banned due to their strong damaging effects on atmospheric ozone.

Determination of the best charge of air conditioner refrigerant z*_maintenance

　　Refrigeration network: The design of each air conditioner has the problem of how to determine the refrigerant charge, especially in the air conditioner that uses capillary tubes as throttling devices, because the capillary tubes have a higher regulating capacity The expansion valve is poor, and the change of the charge has a greater impact on its performance.
