Compare the difference between the refrigerant everything and R22

Choose a proper refrigerant replacement, need to consider many factors and comprehensive evaluation, and should not only conform to the ozone-depleting ozeme depletion potential ( ODP) Ozeme depletion potential and global warming, GWP) Requirements, at the same time should also consider the thermal properties, toxicity, flammability, compatibility, investment and operation cost, etc. The following will be the application of R22 and R134a has a characteristic analysis is as follows: 1, R134a has a global warming ozeme depletion potential ( GWP) To zero. 25, R22 is 0. 36, both belong to the greenhouse gases. 2, everything of ozone-depleting ozeme depletion potential ( ODP) 0, R22 is 0. 6, this is the reason for everything become environmentally friendly refrigerants. 3, R134a has a specific volume is 1 of R22. 47 times, and the latent heat of evaporation is small, so everything refrigerating capacity of the unit is only 60% of R22 unit. Calculated on unit refrigerating capacity price, the price of R22 unit about everything about 60% of the unit. 4, everything's thermal conductivity than R22 fell by 10%, so everything of the unit heat exchanger heat transfer area need to be more big. 5, R134a has a strong water imbibition, 20 times that of R22, so greater demands of the dryer in the unit system, to avoid ice blocking phenomenon. 6, everything is larger than that of R22 in rubber material swelling effect is stronger, in actual operation and mid-cooling medium leakage rate is higher. In addition to copper corrosion resistance is stronger, in use process will happen 'copper plating phenomenon', so must add additive in the system. 7, everything system requires a dedicated compressor and special lipid lubricating oil, lipid lubricating oil with high water absorbability, high foaming ability and high diffusivity, on the stability of the system performance inferior to R22 system used in the mineral oil. 8, everything HFCs refrigerant and its special lipid oil prices are higher than that of R22, the operation of the equipment maintenance cost is higher. HFCs called environmental protection refrigerants of other refrigerant R410A, R440A, R407C, although in terms of efficiency is superior to everything, but there is also work pressure is too high, the piping components optimization and high pressure requirements, must improve the heat exchanger and the unit design, investment, operation maintenance cost higher shortcomings, in terms of the application of large refrigeration unit at this stage is not adapt to our country's basic national conditions, this is the international convention for the ease of use fixed number of year of HCFCs in developing countries, is also a result of collective effort for developing countries. To sum up, in the short term there is no ideal refrigerant, refrigerant R22 at this stage in our country compared with R134a has a kind of environmental protection refrigerants, still has the advantages of high efficiency, stability, cheap, in the aspect of the application of large refrigeration unit will also be in a dominant position, in an ideal refrigerant before birth, R22 refrigerant can also be consumption by 2040.
