4. HVAC AND REFRIGERATION SYSTEM71 Bureau of Energy EfficiencySyllabusHVAC and REFRIGERATION SYSTEM :Vapor compression REFRIGERATION cycle, Refrigerants,Coefficient of performance, Capacity, Factors affecting REFRIGERATION and Air conditioningsystem performance and savings absorption REFRIGERATION SYSTEM : Working principle, Types and comparison withvapor compression SYSTEM , Saving IntroductionThe Heating, Ventilation and Air Conditioning (HVAC) and REFRIGERATION SYSTEM transfers theheat energy from or to the products, or building environment.

Until now, only one HFC based refrigerant, HFC 134a, has been developed. HCFCs are comparatively simpler to produce and the three refrigerants 22, 123, and 124 have been devel-oped. The use of HFCs and HCFCs results in slightly lower efficiencies as compared to CFCs, but this may change with increasing efforts being made to replace CFCs.

In some more recent boiler houses, the problem has been alleviated by mounting the hoppers over the boilers on calibrated load cells, but these are yet uncommon.
