What is the relationship between DuPont refrigerant and Como refrigeration?

Dupont refrigerant is the same as Comu refrigeration.

Refrigerant can be divided into three categories: high temperature (low pressure) refrigerant, medium temperature (medium pressure) refrigerant and low temperature (high pressure) refrigerant. ? Refrigerant is mainly ammonia, freon, water and a small amount of hydrocarbons.

Refrigerant, also known as refrigeration working medium, is a kind of material that can act as a thermodynamic cycle of gasification and condensation in refrigeration system to achieve the purpose of refrigeration or heating.

Refrigerant is liquid, but it can become gas at a certain temperature, that is, it can evaporate in the evaporator of refrigeration system and absorb heat from the cooled object, and then transfer heat to the surrounding medium (water or air) in the condenser to become liquid medium. There are many kinds of refrigerants, among which ammonia and freon are commonly used in air conditioning.

Extended data:

Traditionally, the refrigerant of air conditioner is R 12. Now R600a or R 134a also has mixed refrigerants. Water content ≤ 0.001.002 0.005%.

R 12 molecular formula CCl2F2；; Cl2CF2 Chinese name dichlorodifluoromethane. R 134a chemical molecular formula: (CH 2 FCF 3) purity ≥ 99.9%, water PPm≤ 0.00 10 Chinese name: tetrafluoroethane. R600a Chinese name: isobutane English name: isobutane molecular formula: C4H 10 slightly soluble in water, soluble in ether. The less water in any refrigerant, the better.
