How to work with R410a refrigerating medium?
R410A is meant to be used in new R22 and R13B1 plants. It constitutes of mixed in equal mass portions refrigerating mediums R32 and R125. Neither of forming components contains chlorine, because of this mix is characterized by zero ozone destroying potential (ODP) value. Due to the increased specific cold-productivity, it is possible to reduce the size of main elements of hydraulic contour: heat exchangers, pipelines are possible. In addition R410A is an pseudoazeotropic mix, in other words its temperature during phase transition is virtually stable. Therefore upon leakage ratio of mixture in contour is virtually unchanged, what allows adding the required amount of mixture after leakage without the complete refrigerating medium regeneration. In addition this new refrigerating medium has considerably higher working pressure value. For example at the dew point 43 R22 has the pressure 15,8 atm, and R410A – nearly 26 atm. Therefore, a simple replacement of R22 with the new refrigerating me
