R410A: It is a new type of environmentally friendly refrigerant that does not destroy the ozone layer. Its working pressure is about 1.6 times that of ordinary R22 air conditioners, and its cooling (warming) efficiency is high. R410A new refrigerant is composed of two quasi-azeotropic mixtures R32 and R125 with 50% each. At the same time, because 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 to a certain extent. R410A was once recognized internationally as a suitable refrigerant to replace R22, and has been popularized in Europe, America, Japan and other countries. Global trends and prospects of R410A replacement in major international markets, usage status and entry into international markets.
With the enhancement of people's awareness of environmental protection, people's requirements for product environmental protection are getting higher and higher. Compressor refrigerants range from: R12 R22, R134a, R407C to R410A, 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 damage the ozone layer, but has a high greenhouse effect (GWP is 1730). People began to start with the greenhouse effect, and launched more environmentally friendly and efficient refrigerant compressors. R32 has a higher greenhouse effect (GWP is 670) and R290 (GWP is 3.3).
Recently, H.Stars fully launched the 20STB series of chillers using a new generation of environmentally friendly refrigerants to the Chinese market. The unit adopts R410a new environmentally friendly refrigerant, which has zero damage to the atmospheric ozone layer and large latent heat of evaporation, which can increase the energy efficiency ratio of the air conditioner by about 10%, and has high cooling and heating efficiency.
