Basic thermophysical and operational properties of the refrigerant R409A designed for the retrofit of refrigeration systems with the replacement of R12 are described. It is shown that use of R409A instead of R12 won’t involve the necessity of change of refrigerating equipment. Cases of successful operation of refrigeration systems working on R409A after retrofit are described.
