Refrigerants, also known as refrigerants, are substances that are used as a medium for energy conversion in various heat engines. These substances usually increase power by reversible phase changes (e.g. gas-liquid phase change). In a refrigeration system, the refrigerant acts as a heat transfer agent. It can circulate continuously in the refrigerator, absorbing heat from the object or space to be cooled and evaporating in the evaporator so that its heat is transferred to the surrounding medium in the condenser. When condensed into liquid state, the cooling effect is achieved through the refrigeration system.
Refrigerants are commonly used to cool refrigerators, air conditioners, and automobile air conditioning equipment. For example, R134a is mainly used in most areas where R-12 refrigerant is used, including refrigerators, freezers, water dispensers, automotive air conditioners, central air conditioners, dehumidifiers, cold storages, commercial refrigeration, ice and water dispensers, ice-cream machines, frozen condensing units and other refrigeration equipment.R410A is mainly used as a substitute for R22 and R502, and is characterized by its cleanliness, low toxicity, non-flammability, and good refrigeration effect, and it is used in large quantities in R410A is mainly used to replace R22 and R502, with clean, low toxicity, non-flammable, good cooling effect, etc. It is used in a large number of household air conditioners, small commercial air conditioners and household central air conditioners.
In addition, the refrigerant can be used in other applications, such as aerosol propellants, medical aerosols, insecticide projectiles, polymer (plastic) physical blowing agents, and magnesium alloy protective gases.
