An experimental investigation of the global environmental impact of the R22 retrofit with R422D

Aprea, Ciro; Maiorino, Angelo - In: Energy 36 (2011) 2, pp. 1161-1170

In recent years a new refrigerant, R422D, has been introduced as substitute of R22 for refrigeration systems. This new fluid is an easy-to-use, non-ozone-depleting HFC refrigerant and, differently from its predecessor (R407C), it is compatible with mineral oil. However, R422D has a very high...
