Uses: as refrigerating fluid
R32, also known as difluoromethane and carbon difluoride, is colorless, odorless, and has a safety level of A2. R32 is a Freon substitute with excellent thermodynamic properties. It has the characteristics of low boiling point, low vapor pressure and pressure, large refrigeration coefficient, zero ozone loss value, small greenhouse effect coefficient, combustible and explosive. The combustion limit in the air is 15%~31%, and it will burn and explode in case of an open flame.
Workshop and Shipment Glance
R32 has a low viscosity coefficient and a high thermal conductivity. Although R32 has many advantages, R32 is a flammable and explosive refrigerant. The installation and maintenance of air-conditioning is inherently dangerous. Now coupled with the uncertain factors of R32, safety issues have to be considered. The installation and welding of R32 refrigeration equipment must be vacuumed.
