Heating, Ventilation and Air Conditioning
Energy consumption of a centralized heating, ventilating and air-conditioning (HVAC) system depends on the selection of individual components and their integration in the entire system. Major variations include the type of condenser for heat rejection, chilled-water pumping scheme and efficiency of the chiller and boiler. This chapter, through its tutorials, explains the method of modelling central HVAC systems. Different variations of systems are explained, such as types of chillers, cooling towers and the use of variable-speed drives in HVAC components. The impact of each variation on energy consumption is also explained.
