PERFORMANCE EVALUATION OF MULTIPLE AIRCONDITIONING SYSTEMS PROVIDING SIMULTANEOUS COOLING AND HEATING FOR BUILDINGS


Multiple air conditioning systems for buildings have been widely installed in small, medium and large buildings. These systems are classified into the two types. The one type is the simultaneous system, and the other type is the changeover system. Generally, the former system is better than the latter system in flexibility, and worse in cost. But, in terms of actual
energy efficiency, it is not clear whether the simultaneous system or the changeover system is better. The question noted above will be solved by this research. For calculating the annual energy consumption, we used LCEM tool and the equipment performance characteristics which is experimentally obtained and we clearify the enegy
consumption of noted above two systems under a given set of conditions of buildings.
