First of all, it’s important to understand that the refrigerant—commonly referred to as the refrigeration working fluid—is also known as “xuezhong” in southern regions. It achieves cooling by continuously circulating through the refrigeration system and undergoing phase changes. Specifically, the refrigerant absorbs heat from the cooled medium in the evaporator, turning into a gas, and then releases heat and condenses back into a liquid in the condenser, repeating this cycle.
What are the common types of refrigerants?
1. Inorganic compounds such as water, ammonia, and carbon dioxide;
2. Freons include derivatives of saturated hydrocarbons (such as methane and ethane), among others. For example: R22, R134a, and so on.
3. Saturated hydrocarbons such as propane and isobutane;
4. Unsaturated hydrocarbons such as ethylene and propylene;
5. Azeotropic refrigerant mixtures such as R502;
6. Non-azeotropic refrigerant blends such as R407C and R410, among others;
