Consider a house whose annual air-conditioning load is estimated to be 120,000 kWh. The unit cost of electricity is RM0.218/kWh. Two air- conditioners are considered. Air-conditioner Daekon has a seasonal average COP of 3.3 and cost RM3299 to purchase and RM200 to install. Air conditioner Panasini has a seasonal average COP of 5.0 and cost RM6199 to purchase and RM300 to install. Each air-conditioner requires RM50 service fee each year. All else being equal, determine which air-conditioner is a better buy in a long run.
