Update on Refrigerants: Past, Present and Future

In recent decades, the refrigeration and air conditioning sciences have been in a state of flux primarily because of the phase-out of ozone-depleting CFC and HCFC refrigerants, and secondarily because of environmental concerns related to the direct global warming impacts of some of the replacement refrigerants.  Due to these concerns, there is significant worldwide interest in using substances that are naturally occurring in the biosphere as refrigerants, which are considered benign to the environment and are termed “natural working fluids”.  Surprisingly, many of these substances were already used as refrigerants at the dawn of the refrigeration technology in the late 1800’s.   Thus, when looking at the refrigerants of the future, it is essential to understand which substances have been used in past.  This presentation provides a detailed review of the past and present refrigerants, and proposes refrigerants and their respective technologies that could be used in the future.  An assessment of their characteristics related to choice of one versus another, and an identification of trends set by these choices will be made.
