What is the new refrigerant of R410A and what are its advantages in air conditioning applications

What is the new refrigerant of R410A and what are its advantages in air conditioning applications Recently, many users are familiar with the term inverter air conditioner, but do they feel strange to another term—new refrigerant? In fact, new refrigerant is just a kind of refrigerant that air conditioners must have when running. And because the performance of this refrigerant in product characteristics is more stable, environmentally friendly and healthy, the new refrigerant also has a good development trend and is developing as a new type of air-conditioning refrigerant. Today, the editor of okmarts.com will give you a detailed explanation of what is a refrigerant, what is a new refrigerant, and what advantages the new refrigerant has.

What is the new refrigerant of R410A and what are its advantages in air conditioning applications?

　　What is a refrigerant?

　　 We must first understand what refrigerant is. Refrigerant is also called refrigeration working fluid, and in some places it is called refrigerant. It is a working substance that continuously circulates in the refrigeration system and changes its state to achieve refrigeration, and absorbs the heat of the cooling medium in the evaporator to vaporize, and at the same time transfers the heat to the surrounding air or water in the condenser. Condensation.

Nowadays, there are two kinds of refrigerants that often appear on the market, namely R22 refrigerant and R410A refrigerant. However, because R410A, a new refrigerant, has a great advantage in the use process, its advantages make it become The future development trend of Daikin air-conditioning refrigerants.

　　 So what is the new refrigerant of R410A?

The new R410A refrigerant is made of two quasi-azeotropic mixtures, mainly composed of hydrogen, fluorine and carbon (expressed as hfc). It has the advantages of non-toxic, stable, and superior performance. However, it does not contain chlorine. Element, so it will not react with ozone, and accordingly will not destroy the ozone layer. Therefore, in terms of performance, if a new refrigerant air conditioner is used, there will be a certain improvement. R410A is by far the most suitable and best refrigerant internationally recognized to replace R22. This refrigerant has gained great popularity in Japan, Europe, America and other countries.

R410A is a kind of mixed refrigerant. It is a mixture composed of R32 (difluoromethane) and R125 (pentafluoroethane). It can be used according to specific requirements and can be used for various properties, such as easy A refrigerant synthesized by considering flammability, capacity, exhaust temperature and efficiency. The physical characteristics of R410A are colorless and turbid in appearance, volatile, boiling point -51.6℃, freezing point -155℃; its main characteristics are:

　　(1) Will not destroy the ozone layer. Because the new refrigerant does not contain chlorine in its molecules, its ozone depletion potential (ODP) is zero. The global warming potential (GWP) is less than 0.2.

　　(2) Has very low toxicity. The allowable concentration is 1000 ppm as R22.

　　(3) It is non-flammable. The flammability in the air is almost zero.

　　(4) It has the characteristics of high thermal stability.

　　(5) It has the same water solubility as R22.

　　(6) is a mixed refrigerant composed of two refrigerants.

　　(7) It is not compatible with mineral oil or alkylbenzene oil. (Compatible with POE[Ester Lubricant], PVE[Ether Lubricant])
