Refrigerant, also known as refrigerant and snow seed, is the medium material through which various heat engines complete energy conversion; Such substances usually increase power by reversible phase transitions. At present, the refrigerant used by most air conditioners on the market is R22, commonly known as Freon, and its scientific name is CHCIF2. So why does the Kcalin air energy heat pump use R410A refrigerant, and what is the difference between it and R22?
1. From the aspect of material, R22 is a single working medium; R410A is a mixed refrigerant, which is composed of R125 and R32 in a ratio of 1:1.
2. R22, scientific name CHCIF2, contains fluorine, is destructive to the ozone layer and does not meet the current energy conservation and environmental protection requirements. It will be restricted after 2030. R410A is fluorine-free and an environment-friendly refrigerant, which is widely used in the field of heat pump.
3. From the comparison of heating effect, the air source heat pump using R22 refrigerant has relatively good heating effect.
4. R410A is a new type of refrigerant with mixed proportion. The pressure of R410A is on the high side, and its pressure is 1.6 times of R22 in both balance and operation. It does not destroy the ozone layer and has high cooling efficiency.
Generally speaking, refrigerant is a substance that is easy to absorb heat and change into gas, and easy to release heat and change into liquid. The ideal refrigerant is non-toxic, non-explosive, non-corrosive to metals and non-metals, non-flammable, easy to detect when leaking, chemically stable, non-destructive to lubricating oil, with high latent heat of evaporation, and harmless to the environment.
