  SPECIFIC REFRIGERANTS CLASS NOTES  FOR MECHANICAL ENGINEERING Different refrigerants have different properties. Different applications require different refrigerants. Their selection is a compromise of properties for an application. Ammonia suits best for large scale cooling requirements. There is a prohibition on the manufacture and use of R-11 and R-12. These have high Ozone depletion & Global…
