ABSTRACT
Refrigerants are the working fluids that circulate around a
refrigeration system, absorbing heat from areas to be
cooled and transferring it to where the heat can be dissi-
pated. A variety of refrigerants are available for different
cooling/freezing applications. In the food industry, the
most commonly used refrigerants are ammonia and freons,
but in the recent years, the trend has been to move away
from freons and to look for more environment-friendly
compounds.
