R407C
The refrigerant is made up ofHFCThe substance is composed of a mixed refrigerant without any ozone depleting substanceODPThe value is zero.R407CPerformance andR22Very close, to maximize the use of existingR22System design, replacement of refrigerant, only a small number of components to replace or adjust. BecauseR407CFor the non azeotropic refrigerant, the transformation process of the existence of temperature slip is larger, and therefore can not be used as a full liquid type evaporator heat exchanger, and add in the customer service repair process, in some cases, may need to drain refrigerant remaining in the system and then re filling; at the same time in order to ensure the refrigerant composition does not change,R407CIt must be charged in liquid form.R407CIt's the home air conditionerR22Transitional substitutes for refrigerants.

R407CMain applications of refrigerants
R407C 
Mainly used in household air conditioning, small and medium-sized central air conditioning, room air conditioning, temperature removal machine, automotive air conditioning, marine air conditioning, etc..

R407CReference oil for refrigerants
The vast majority of compressor manufacturers recommend the use ofPolyol esterPOEPolyol EsterRefrigerator oil.
