项目摘要

The adaptability of HVAC system with building structure thermal storage was confirmed, and, in addition, the basic research for the overall air-conditioning system that the radiation, ventilation, and the moisture control are possible was done in medical health facilities where the heat load was small.1)Recently cases that social welfare facilities for the aged and hospitals install the electric floor heating systems using latent/sensible heating storage materials are increasing in number. This system, utilizing the radiant heat and heating from the floor, offers the comfortable environment even if the room temperature is kept lower than normal. However, the investigation for the quantitative examination of the space heating effect of the system has been rarely carried out. In this research, we proposed the design guidelines and operation guidance of the electric floor heating systems using latent/sensible heating storage materials in the Kyushu area.2)The investigation analysis of the indoor thermal environment, the amount of heat stored in the slab, and the power consumption load shifting ratio in the office building where thermal mass storage system with air insufflations in ceiling plenum and ice thermal storage system was used together, was carried out. As a result, it was clarified that indoor thermal environment was in ASHRAE comfortable region, the load shifting ratio of the amount of power consumption was 60%, and 14% in that was contribution of the building mass thermal storage.3)The energy efficiency of HVAC system and the indoor environment of the building, where the building thermal mass storage with raised floor and the ice thermal storage system using together were adopted, were examined. As a result, it was clarified to achieve the indoor thermal environment and the effect of the load leveling the same as the expectation.

确认了暖通空调系统与建筑结构蓄热的适应性，并在热负荷较小的医疗卫生设施中，对整体空调系统进行了辐射、通风、控湿的基础研究。1)最近，社会福利设施和医院使用隐热/显热储存材料安装电地暖系统的案例越来越多。该系统利用辐射热和地板供暖，即使室温低于正常温度，也能提供舒适的环境。然而，对该系统的空间热效应进行定量研究的研究却很少。在本研究中，我们提出了九州地区使用潜热/显热储热材料的电地暖系统的设计指南和操作指南。2)对吊顶充风蓄热系统与冰蓄热系统同时使用的办公楼室内热环境、楼板蓄热量、能耗负荷转移比进行了调查分析。结果表明，室内热环境处于ASHRAE舒适区，耗电量的负荷转移比为60%，其中14%为建筑质量蓄热贡献。3)考察了采用活动地板建筑蓄热系统和冰蓄热系统共同使用的建筑暖通空调系统的能效和室内环境。结果表明，达到了预期的室内热环境和负荷均衡效果。
