 MackFri®-R22 refrigerant. It has low ozone depletion potential (ODP = 0,05), not high global warming potential (GWP = 1700), that is, ecological substances of R22 are much better than those of R12 and R502. This clear gas with weak smell of chloroform is more poisonous than R12, non-explosive and incombustible. Compared to R12, R22 refrigerant is worse soluble in oil, but it easily penetrates through looseness and neutral to metals. Refrigerating industry produces refrigerating oils of high quality for R22. Under temperature higher than 330 oC, R22 is decomposed at the presence of metals, thus, forming the same substances as R12. R22 refrigerant is poorly soluble in water, moisture volume fraction in it should not exceed 0,0025%. Heat transfer coefficient during boiling and condensation is 25...30% higher than that of R12; however, R22 has higher condensation pressure and discharge temperature (in refrigerating machines). R22 tolerance concentration in the air is 3000 mg/m3 under exposure of 1 hour. This refrigerant is widely used to obtain low temperatures in compression refrigerating facilities, in the conditioning systems and heat pumps. In refrigerating facilities, operating on R22, it is necessary to use mineral or alkyl benzene oils. You cannot mix R22 with R12 - azeotrope blend will be formed.
