Trifluoromethane falls under which refrigerant group?

Trifluoromethane, also known as HFC-23, is classified under the refrigerant group A1. The A1 designation indicates that the refrigerant is non-toxic and has low flammability. In the context of refrigerants, the classification system helps in determining the safety and handling requirements during use and in various applications.

Group A1 includes substances that pose a minimal hazard, making them safer options for refrigeration and air conditioning systems. Understanding the refrigerant classification is crucial for compliance with safety standards and regulations, ensuring that technicians and users are properly informed of the characteristics and risks associated with the refrigerants they are handling.

In general, refrigerant classifications are based on flammability and toxicity ratings established by organizations like the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). These classifications enable industry professionals to select appropriate refrigerants based on the specific demands and safety considerations of their systems.
