| Abstract | ||
| This research studies the life cycle cost analysis using detailed cooling and electrical load profiles to calculate initial and running costs to evaluate the economic feasibilities of three different types of air conditioning systems as residential air conditioning system (RACs), commercial air conditioning system (CACs) and multi power air conditioning system (MPACs). The present-worth cost method for life-cycle cost period for ten (10) years analysis is applied to a sample building located in Mosul city / Iraq so as to select the best air conditioning system. The cooling load temperature differential with cooling load factor (CLTD/CLF) was used with hourly analysis program (HAP v4.6) for the estimation cooling load in each room of apartment. The results showed that the RAC system is lower than CAC and MPAC systems in initial cost approximately 53% and 67% respectively and the running cost for CAC system is lower than RAC and MPAC systems approximately 12% and 7% respectively for one month. The the total cost for two systems RAC and CAC are equal after 20 months of the beginning run and after even break point (BEP) the total cost for CAC system began to decline which indicates there is save in electric consumption and present worth cost over a period of (10) ten years after operation interval. The CAC system uses duct always to distribute air into each condition zone, therefor this system gives less noise of air distribution with best interior aesthetic appearance so that it fits with the interior decoration for each rooms of apartment. The outdoor unit of CAC system doesn’t appearance because the system working for long distances and can put outdoor units on the roof of the building. | ||
