CO2 refrigerant is the future in HVAC field

Environmental protection: The refrigerants R22/R134A/R410a are harmful to the environment. According to the amendments to the Montreal Protocol, developed countries like the United States will gradually reduce the production and consumption of hydrofluorocarbons starting from 2019. Over 100 developing countries, including China, will freeze the consumption and production of HFCs from 2024. On the other hand, CO2 refrigerant is odorless, non-irritating, non-flammable, non-explosive, easy to obtain, and 100% environmentally friendly.
