空調空間の特性の違いが空調システムの制御に与える影響

抄録

To date, although performance evaluation of air conditioner considering both of room and air conditioner has been done to realize high efficiency operation in the actual environment, control system of air conditioning has not been considered sufficiently. Therefore, in this study, we simplify the control system of air conditioning and reveal the room temperature change and the other responses against step input of preset temperature to know the effect of air conditioning system on the room temperature control. Also, we considered the effect of trying to keep air and objects in the room at the same temperature as the room characteristic and expressed it by heat transfer coefficient. As a result, it was revealed that it can take time for the room temperature to reach preset temperature and the overshoot can become bigger when heat transfer coefficient is changed even in the simple room. The results show that the control performance of air-conditioning system can be inefficient when the room characteristics is changed.
