The center of the air can heat pump high efficient heating material: common refrigerant analysis

every mention of refrigerant ( Refrigerant) , most people first think of is air conditioning. In the context of daily life, air conditioning is every family unit, use frequency is quite high. We want to talk about today, however, are not air conditioning, but with air can heat pump air conditioning with similar principle. First used for refrigeration and air conditioning, primary air can heat pump for heating. Heating principle of the heat pump is the inverse of air conditioning refrigeration principle, through the refrigerant to absorb heat from the air. Therefore, said refrigerant in the heating of air can play a most crucial effect also have not cannot. 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 fission air conditioner and central air conditioning system, can say is everywhere. However, the lack of it has one of the biggest is that it is a member of the freon clan, into the air, is likely to ozone formation damage, 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, also not to damage the ozone layer formation. Looks like is very perfect, but its boiling point is low, as long as. . . 26. 5 ℃, this means that, if it is used in heat pump, once the temperature drops, so the amount of refrigerant in the gasification will have fallen sharply, led to the decrease of the heat pump heating power. Therefore, this kind of refrigerant R22 than widely used, is commonly used in indoor perhaps tropical. R290 refrigerant

R290 is another kind of new environmental protection refrigerant, colorless, slightly soluble in water, does not contain ozone. But not enough high safety coefficient. If there is a probability must be mixed with air, attack bums, if there are any open flame, easy cause trouble. Now, in the professional use of high purity of R290 refrigerant as heat medium.

from the perspective of a continuous emphasis on energy conservation and environmental protection in China to carry out the train of thought, air can heat pump refrigerant, and in compliance with environmental protection free from contamination. Heat pump in the future market, the environmental protection refrigerant will certainly has its place.
