R407C Refrigerant

R407C is an environmentally friendly medium and high temperature refrigerant made by mixing R32, R125 and R134a in a certain proportion.R22is used in various air conditioning systems and non-centrifugal refrigeration systems. It is mainly used in household air conditioners, small and medium-sized commercial air conditioners (small and medium-sized unit air conditioners, household central air conditioners, multi-connect), mobile air conditioners (car air conditioners, etc.), dehumidifiers, freeze dryers, marine refrigeration equipment, industrial refrigeration and other refrigeration equipment.

R407C is the easiest alternative to Freon R22 in newly installed refrigeration equipment (usually air conditioning systems); However, since R407C and R22 are different in physical and chemical properties, theoretical cycle performance, and compressor oil, for after-sales maintenance of refrigeration equipment initially installed with R22 refrigerant, if additional refrigerant needs to be added or replaced, R22 can still only be added. R407C cannot be directly used to replace R22.(In other words, replacement by replacement is usually not possible; but for refrigeration equipment newly installed and using R22, R22 can be directly replaced with R417A during maintenance or replacement).
