1. Precautions of refrigerant leakage
The air conditioner system uses R22/R407C as its refrigerant which itself is no harm to human body and nonflammable
safety refrigerant. But the room for installing the system should reach a certain space in order to avoid exceeding
critical concentration in case of leakage. Other precautions could be taken also.
Critical concentration is a noxious gas concentration that is not so harmful to personnel but needs to treat urgently.
The critical concentration of R22/R407C is 0.3kg/m
