Air can heat pump commonly used refrigerants have what kind of?

And every time said to the refrigerant ( Refrigerant) First of all, most people think of is air conditioning. Indeed, in the context of daily life, almost every household air conditioning installation, application frequency is quite high. However, today we are going to talk about, not air conditioning, but with air can heat pump air conditioning with similar principle. Air conditioning is mainly used in refrigeration, air can heat pump is mainly used for heating. Heating principle of the heat pump is the inverse of air conditioning refrigeration principle, through the refrigerant absorbs heat from the air. Therefore, said refrigerant in the heating of air can also may be the most critical role. Common refrigerant and air can have what kind of? Refrigerant R22 refrigerant R22 is single, scientific name called methylene fluoride a chlorine, the boiling point is about - 41℃。 This kind of refrigerant colorless, odorless, the most widely used in air conditioning system, especially in the fission air conditioner and central air conditioning system, can say is everywhere. However, it has one of the biggest is not enough, that it is a member of the family of freon, into the air, the possible damage to the ozone layer, causing environmental problems. Everything refrigerant R134A has a component composition is different with other refrigerants, it does not contain chlorine ion, have no toxicity, also not flammable in air, will not damage to the ozone layer. Seems to be perfect, but its boiling point is relatively low, only. . . 26. 5 ℃, this means that, if it is used in the heat pump, once the environment temperature is reduced, so the amount of refrigerant in the gasification will be greatly reduced, resulting in a decline in heat pump heating efficiency. Therefore, this kind of refrigerant R22 than widely, commonly used in indoor or tropical. R140A refrigerant R140A refrigerant is scientists to in view of the increasingly worsening of environment and development of an environmental protection refrigerants. It goes with everything, colorless, volatile, flammable. R32 and R125 refrigerant is contained in composition, the boiling point about - 51 ℃ or so and do not contain chlorine ion, also won't destroy the ozone layer, water soluble and R22 matched, but the capacity is increased significantly. R290 refrigerant R290 is another kind of new environmental protection refrigerant, colorless, slightly soluble in water, does not contain ozone. But the safety factor is high enough. If mixed with air and has a certain probability bums, if there are any open flame, it is easy to cause accident. Now, in the industry use of high purity as refrigerant R290 as heat medium. From the perspective of the development of our continuous emphasis on energy conservation and environmental protection, air can heat pump refrigerant development, also in the environmental protection free from contamination. Air can heat pump in the future market, environmental protection refrigerant will certainly has its place.
