A desiccant system is effective in reducing an energy consumption. However, the energy saving effect of the system in winter period is unexplained. Additionally, the complexity of desiccant system makes optimal control difficult. And so, the automatic control system is expected to solve this problem. In this study, we developed an automatic control system for Air-conditioner that makes Predict Mean Vote (PMV) thermal neutral and measured an electricity consumption of Air-conditioner and indoor environmental factors using the developed system. As a result, AC control by the developed system, PMV indicated within a range of ±0.3 that is same value in case of AC control with fixed preset temperature 24℃. Moreover, the energy consumption of the AC control by developed system was lower than AC control with fixed preset temperature 24℃. From the above, the developed system affected reducing heat load. Furthermore, an energy consumption of the desiccant system was calculated. As a result, the desiccant system was effective in case of more than three rooms controlling Air-conditioner.
