I have surveyed air conditioner operating conditions and indoor environment of houses in relation to their thermal insulation performance in Kansai (Kyoto, Kobe city), Tohoku (Aizu-wakamatsu city) and Hokkaido (Kitami city). In Aizu-wakamatsu and Kitami, air conditioners were used since morning when ambient temperature exceeded 25℃, and the average room temperature was 26〜27゜C. In Kyoto and Kobe, however, the utilization of air conditioners in the daytime was little, and they were used only during the period between the evening and pre-sleep time, and the average room temperature was 28〜30℃. The difference in such utilization by the thermal insulation performance was small because people in Kansai lived in their houses with their windows opened. They had the impression that high-insulated houses kept in the heat due to their insufficient ventilation performance even if a maximum room temperature was low.. In Kyoto and Kobe, habituation for a heat and apprehensions on the health concern … More ing air conditioner use, discomfort of top and bottom temperature gradient have reduced the utilization of air conditioners.In Aizu-wakamatsu, air conditioners frequently repeated the on/off operation when each air conditioner in all rooms was utilized at the same time since such use resulted in the excessive capacity of electricity and exceeded the range of the inverter control.I confirmed such air conditioner on/off operation leaded to the extreme drop in efficiency by the experiment. However, the on/off operation did not occur in Kitami since it has been air-cooled by 1 air conditioner in all rooms. From the viewpoint of its efficiency, it is desirable that a high thermal insulation house install an air conditioner in second floor hall etc. and it continuously keep the room temperature.I developed "Room temperature and load fluctuation analysis program" in which the accuracy of the calculation of the external wall with vent layers was improved. It was clarified that adopting a higher thermal insulation performance than that defined in the energy saving standard to houses in warmer areas also resulted in period cooling load decrease. Less

我已经调查了房屋的空调操作条件和室内环境，与他们在Kansai（Kyoto，Kobe City），Tohoku（Aizu-Wakamatsu City）和Hokkaido（Kitami City）的热隔热性能有关。在Aizu-Wakamatsu和Kitami中，自早晨的环境温度超过25℃以来，使用了空调，平均室温为26-27℃。然而，在京都和科比，白天的空调利用很少，仅在晚上和睡眠前的时间内使用它们，平均室温为28-30。热绝缘性能在这种利用中的差异很小，因为堪萨斯的人们住在房屋中，窗户打开了。 They had the impression that high-insulated houses keep in the heat due to their insufficient ventilation performance even if a maximum room temperature was low.. In Kyoto and Kobe, habituation for a heat and apprehensions on the health concern … More ing air conditioner use, discomfort of top and bottom temperature gradient have reduced the utilization of air conditioners.In Aizu-wakamatsu, air conditioners frequently repeated the on/off operation when each air conditioner in all由于这种使用导致了过多的电能，并超过了逆变器控制的范围，因此同时使用了房间。我确认了这种空调的开/关操作导致实验的效率极高下降。但是，由于在所有房间中都由1个空调对其冷却，因此在Kitami中没有发生ON/OFF操作。从其效率的角度来看，需要高热绝缘室在二楼大厅等安装空调。它继续保持室温。我开发了“室温和负载波动分析计划”，其中改善了使用通风板层计算的外墙计算的准确性。可以澄清的是，采用比在温暖区域中的储蓄标准中定义的更高的热隔热性能也导致周期冷却负荷减少。较少的
