Machine Structure and Installation

Refrigerant

This air conditioner uses R32 refrigerant, which is a special, purified refrigerant. R32 is mildly flammable and odorless. While it can cause explosions under certain conditions, its flammability is very low and requires a direct flame to ignite. Compared to conventional refrigerants, R32 is environmentally friendly, does not harm the ozone layer, and has a lower impact on global warming. It also offers high energy efficiency, requiring less refrigerant charge.
