Consider a building whose annual air-conditioning load is estimated to be 120,000 kWh in an area where the unit cost of electricity is RMO.10/kWh, as shown in Figure 4 below. Two air conditioners are considered for the building. Air conditioner A has a seasonal average Coefficient of Performance, COP of 3.2 and costs RM5,500 to purchase and install. Air conditioner B has a seasonal average COP of 5.0 and costs RM7,000 to purchase and install. All else being equal; analyse both possibilities and determine which air conditioner is a better buy. 120,000 kWh A B Air cond. Air cond. COP = 3.2 House COP = 5.0 120,000 kWh
