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.

证实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机构中进行了可实现辐射、通风、控湿的整体空调系统的基础研究。 1）近年来，社会福利机构、医院等采用潜热/显热蓄热材料安装电地暖系统的案例不断增多。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，对系统的空间供暖效果进行定量检验的研究却很少开展。本研究提出了九州地区采用潜热/显热蓄热材料的电地暖系统的设计指南和运行指导。2)对同时使用天花板充气蓄热系统和冰蓄热系统的办公楼的室内热环境、板蓄热量和用电负荷转移率进行了调查分析。结果表明,室内热环境处于ASHRAE舒适区,用电量的负荷转移率为60%,其中14%是建筑大容量蓄热的贡献。3)对采用高架建筑大容量蓄热和冰蓄热系统并用的暖通空调系统能效和建筑室内环境进行了检验。明确了室内热环境和负荷均衡的效果与预期一致。
