自然通風を行う住宅の室内温熱環境および空調エネルギー消費予測手法の開発

抄録

In this paper, the relation between utilization of air conditioner and indoor thermal environment was examined, and occupants' indoor thermal environment control behavior was modelized. Besides, a method to estimate indoor thermal environment and air conditioning energy consumption in a residential house with both natural ventilation and air conditioner was developed. By applying this method to a standard house model, the effects of natural ventilation on indoor thermal condition and air conditioning energy consumption in Osaka were grasped. The results are as follows: (1) When air conditioner was turned on, average indoor SET^* was about 19℃ in heating season and 27℃ in cooling season. Therefore, agreeable thermal environment in room without air conditioning is between 19℃ and 27℃ by SET^*. (2) It is clear that the method developed in this paper is able to estimate indoor thermal environment and air conditioning energy consumption with reasonable accuracy. (3) Utilization of fan enables air conditioning energy consumption at living room to be reduced by about 35 %.
