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. Energy in form of electricity orheat is used to power mechanical equipment designed to transfer heat from a colder, low-ener-gy level to a warmer, high-energy deals with the transfer of heat from a low temperature level at the heatsource to a high temperature level at the heat sink by using a low boiling are several heat transfer loops in REFRIGERATION SYSTEM as
Li-Br-water absorption refrigeration systems have a Coefficient of Performance (COP) in the range of 0.65 – 0.70 and can provide chilled water at 6.7 °C with a cooling water temperature of 30°C. Systems capable of providing chilled water at 3 °C are also available.
