9. pseudo azeotropic characteristics R410A is a pseudo azeotropic mixture comprising the two components R32 and R125 Multi component refrigerants with these chemical characteristics exhibit little compositional change even from phase changes due to vaporization or condensation which means that there is little change in the circulating refrigerant composition even when the refrigerant leaks from the gaseous section of the piping Accordingly R410A can be handled in almost the same manner as the single component refrigerant R22 However when charging because there is a slight change in composition between the gas phase and the liquid phase inside a cylinder or other container charging should basically begin with the liquid side c Pressure characteristics As seen in Table 2 the gas pressure of R410A is approximately 1 6 times as high as that of R22 at the same refrigerant temperature which means that special R410A tools and materials with high pressure specifications must be used for all refrigerant piping work and servicing Table 2 Comparison of R410A and R22 saturated vapor density Unit MPa R22 LIE NUES o __ O eerie 0 i e Se 4 eo gc www ilmal mp pumput com CS PV9CKE CU PV9CKE CS PV12CKE CU PV12CKE Panasonic ilmastointilaitteet korjaa ja huoltaa p kaupunkiseudulla J hdytinpalvelu RefGroup Oy d R410A refrigerating machine oil Conventionally mineral oil or a synthetic o
