The interpretation of the refrigerant so full, so practical

what is the refrigerant? Refrigerant is also called the refrigerating agent, in some areas commonly known as the south snow. It is a cycle in the refrigeration system and through its own state changes to complete assignments refrigeration material. Refrigerant in transpiration in absorption cooling medium ( With air or water, etc. ) Heat and evaporation, in the heart of the condenser heat transfer to the surrounding air or water and condensation. Specific to air conditioning products, we usually say add freon freon, freon is what? Hydrocarbons (freon is full Hydrocarbons) The floorboard of the halogen derivative, as the 30 s of this century with the development of chemical industry and presents a class of refrigerants, it presents the process of refrigerant refrigeration KongDiaoJie seek. From the definition of freon can see, now what is called the non freon R134A has a, R410A and R407c are freon. What refrigerant is used for? To understand this problem have to clear the operation principle of air conditioner, let's take a look at how general air conditioning job. Primary use electricity to air conditioning to compress a gas into a liquid, and then on the cooling side will be liquid evaporation ( Endothermic process) , and the transpiration of gas by the lead back to the compressor back into a liquid ( Exothermic process) , from this cycle, to heat to a succession of big move heaven and earth, to get to the intention of the refrigeration. , while in the air conditioner by the liquid into gas or gas into a liquid for heat transfer is known as 'refrigerant' ( Freon) The material. Refrigerants what type, what is the difference between them? We used some of refrigeration professional fluorine refrigerant R11, R12, R22, R32, R113? , R115, R123, R125, everything, R143A, R141b, R142b, R152, r404a ( 44% R143A R125 and 52% and 4% of the 134 a) 、R407c（ And 25% of the 23% of R32 R125 and 52% of everything) r410a ( And 50% of the 50% of R32 R125) R500 ( 73. 8% of the R12 and 26. 2% of R152) 同( 48. 8% of R22 and 51. 2% of R115) And so on. Freon refrigerant can damage the ozone layer because of the existence of cl element, and follow the cl atom the number of add, damage to the ozone layer to add following h elements to add to the damage of the ozone layer can decrease; Form the first because of the greenhouse effect refrigerants in the process of slow oxidation differentiation and generate a lot of greenhouse gases, such as co2, etc. According to the molecular structure of the freon refrigerant, can be roughly divided into the following three categories: 1, CFCS: referred to as 'CFC, primary R11, R12, R113? , R115, R500, R114, etc. , because of damage to the ozone layer, as well as the biggest, has been the Montreal protocol as a kind of controlled substances. Stop to use, this kind of material is now on the process of production of polyurethane sponge, R11 by R141b as a transitional substitutes. Primary contain CFCS abbreviation as 2, hydrogen, R22, R123, R141b, R142b etc. , the ozone layer damage coefficient is only a few percent of R11, therefore, as type of material is now seen as CFC is a class of the most important transitional instead of material.
