OVERVIEW OF AN AIR CONDITIONING SYSTEM Figure 2 shows an overview of an air conditioning system. Broadly speaking, energy is consumed by heat sources, water pumps, and ventilators. FIgure 2 Overview of an Air Conditioning System A heat source generates cold/hot water through gas bustion in the case of applying a gasbased cold/hot water generator, the cold/hot water is then conveyed to air conditioners by water pumps. Inside air conditioner, the cold/hot water is flowing through heat exchange equipment where air is warned up or cooled when passing through the heat exchange equipment via ventilators and then the warned/cooled air is blown to an area through ducts. Water pumps are mainly classified into primary pumps, secondary pumps, and cooling pumps, but their power consumption is almos
