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.

1 – 2 Low pressure liquid refrigerant in the evaporator absorbs heat from its surroundings, usually air, water or some other process liquid. During this process it changes its state from a liquid to a gas, and at the evaporator exit is slightly superheated. 4. HVAC and Refrigeration System Bureau of Energy Efficiency 72
