Abstract
When designing a usual air-conditioning system, the setting of room temperature, an exit temperature of the heat source, etc. are fixed. However, if these elements are changed to the best setting according to the situation that changes hour by hour, there is a possibility that further energy conservation can be achieved. In optimization, a set value may not be the best, because the thermal load prediction includes the error margin. Therefore, it proposes the more reliable optimization technique with considering the thermal load prediction error margin. Then this effect is examined by using simulation.
