Q Introduction of Refrigerant Gas R410a

A Basic Introduction of R410a Refrigerant Gas：

R410A: It is a new type of environmentally friendly refrigerant, does not destroy the ozone layer, the working pressure is about 1.6 times that of ordinary R22 air conditioners, and the cooling (heating) efficiency is high. R410A new refrigerant is composed of two quasi-azeotropic mixtures R32 and R125 each with 50%, mainly composed of hydrogen, fluorine and carbon elements (expressed as hfc), which is stable, non-toxic, and superior in performance. At the same time, since it does not contain chlorine, it will not react with ozone, that is, it will not destroy the ozone layer. In addition, the performance of air conditioners using new refrigerants will also be improved. R410A was once recognized internationally as the most suitable refrigerant to replace R22, and it has been popularized in Europe, America, Japan and other countries. R410A replaces the global trends in major international markets and the outlook for its use and the dynamics of entering the international market.

Physical Properties

R410A, is a kind of mixed refrigerant, it is a mixture composed of 50% R32 (difluoromethane) and 50% R125 (pentafluoroethane). Its advantage is that it can be used according to specific requirements, for various properties, such as Taking flammability, capacity, exhaust temperature and efficiency into consideration, a refrigerant is tailored.
R410A is colorless, non-turbid, volatile, boiling point -51.6℃, freezing point -155℃; its main characteristics are:

(1) Does not destroy the ozone layer. Its molecular formula does not contain chlorine, so its ozone depletion potential (ODP) is 0. The global warming factor (GWP) is 2025.

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

(3) Non-flammable. The flammable polarity in the air is zero.

(4) High chemical and thermal stability

(5) The water solubility is almost the same as R22.

(6) It is a mixed refrigerant, composed of two refrigerants

(7) It is not compatible with mineral oil or alkylbenzene oil. (Compatible with POE[ester lubricant] and PVE[ether lubricant])

Future Prospect of R410a

As people's awareness of environmental protection increases, people have higher and higher requirements for product environmental protection. Compressor refrigerants range from R12, R22, R134a, R407C to R410A, and people’s efforts to environmental protection have not changed. R410A is not the end of the development of environmentally friendly refrigerants but a new starting point. R410A does not harm the ozone layer, but has a higher greenhouse effect (GWP is 1730). People have begun to start with the greenhouse effect again, and introduced more environmentally friendly and efficient refrigerant compressors. R32 has a higher greenhouse effect (GWP is 670) and R290 (GWP is 3.3).

Q Why can R410A refrigerant replace R22 air-conditioning refrigerant?

A R410A refrigerant and R22 refrigerant are the two mainstream domestic air-conditioning refrigerants at this stage. Many people know that R410A is an environmentally friendly refrigerant, and R22 is a Freon that will be eliminated, but it is not clear why R410a is more environmentally friendly than R22. Following Frioflor refrigerant gas will give you an analysis.

First of all, from the point of view of chemical composition, R22 contains chlorine element, chemically named difluorochloromethane, which is one of the freons and belongs to hydrochlorofluorocarbons, so R22 refrigerant has a harmful effect on the ozone layer. R410A refrigerant is a mixture of R125 (pentafluoroethane) and R32 (difluoromethane), which does not contain chlorine and will not destroy the ozone layer.

From the physical performance comparison:

1. In terms of toxicity, R410A is low toxicity, and R22 is slightly toxic, so R410a is safer than R22.

2. The heat transfer capacity of R410A refrigerant is larger than that of R22, the cooling efficiency is higher, and the heat transfer area of the heat exchanger is reduced. Therefore, R410a air conditioners are more energy-efficient than R22 air conditioners, and the system is more stable.

It can be seen that, as a new generation refrigerant, R410A has obvious advantages over the older generation R22 refrigerant. R410a is the internationally recognized best substitute for R22 at this stage and is popularized all over the world.
