Environmental protection cfc-free air-conditioning needs to add fluoride? What is the distinguishing feature of environmental protection refrigerants?

We in the purchase of air-conditioning, cfc-free air-conditioning promoters will introduce environmental protection, we will have a curiosity, cfc-free air-conditioning really no fluorine environmental protection? That he is cooling by what? Of curiosity makes us to understand the environmental cfc-free air-conditioning. If the price is right, then it may choose green cfc-free air-conditioning. Environmental cfc-free air-conditioning in just the rise of the price is very high, than the ordinary air conditioning price twice or even three times. And both in fixed frequency and frequency conversion air conditioning, as long as with cfc-free, environmental protection, so his social status immediately. As the first batch of cfc-free air-conditioning in the domestic market of environmental protection, has been in the past ten years. A group of the first to experience the user already knows, environmental cfc-free air-conditioning, is a matter of fluorine. He just in a way, environmental cfc-free refrigerants. Model, called R410A refrigerant r410a is a new kind of environmental protection, not destruction of the ozone layer, cooling or heating time, the working pressure for the common R22 air conditioner 1. Refrigeration (about 6 times, Warm) More efficient. Improve the performance of air conditioning does not destroy the ozone layer. New refrigerant R410A composed of two kinds of quasi azeotropic mixture, mainly include hydrogen, fluorine and carbon ( Said for HFC) , has the stability, non-toxic, superior performance, etc. At the same time as a result of not containing chlorine, so will not react with ozone, which does not destroy the ozone layer. In addition, the adoption of new refrigerant of the air conditioning in terms of performance also improved. R410A is by far the most appropriate internationally recognized to replace R22 of refrigerant, and in Europe and the United States, Japan and other countries. Used in home air conditioning, the small and medium-sized commercial air conditioning. R410A replacement in the main international market of global trends and prospects of usage and dynamic R410A physical properties data of entering the international market, is a kind of mixed refrigerant, it is by R32 ( Methylene fluoride) And R125 ( Five fluorine ethane) Consisting of a mixture, its advantage is that can be used according to the specific requirements, for a variety of properties, such as flammability, capacity, exhaust gas temperature and efficiency into consideration, tailored to synthesize a kind of refrigerant. R410A appearance not cloudy, colorless, volatile, boiling point - 51. 6 ℃, freezing point - 155℃； Can be seen from the above introduction, environmental protection refrigerant cfc-free, if the disclosure is not refrigeration. But his advantage to refrigerant is much better than the original. At the same time its installation process are more strict. At the time of air conditioning installation must be vacuum. Under the condition of refrigerant leakage, also have to vacuum again after supplying refrigerants.
