摘要:
对顶板和地板辐射供冷的室内热舒适进行研究可为优化供冷系统,提出能够满足人体热舒适的、较为合理的辐射供冷方式提供一定的理论依据。文章阐述了顶板和地板辐射供冷两种辐射供冷模式及其辐射供冷机理,分析了室内热舒适影响因素。以济南市某个应用辐射供冷空调技术的实验房间为研究对象,采用 Airpak构建仿真房间模型,进行数值模拟,从室内垂直温差、PMV—PPD指标及吹风感三方面对比分析了顶板辐射和地板辐射两种供冷方式对室内热舒适的作用效果。结果表明:顶板辐射供冷沿房间高度方向垂直温差小于3 ℃,而地板辐射供冷垂直温差过大,不能满足局部热舒适要求;顶板辐射供冷的PMV值基本处于-0.5~+0.5的范围,人体离最佳热舒适状态最近,而地板辐射供冷只能保证在人体周围取值时能够得到比较满意的PMV值;两种供冷模式对于吹风感的不满意率PD均小于15%,都能满足人体对于吹风感热舒适的要求。
Abstract:
Study of indoor thermal comfort under the condition of the ceiling and floor can provide the oretical basis for opitirnizing the cooling system and meeting the human body thermal comfort. This paper expounds the two types of radiation cooling mode for ceiling radiant cooling and floor radiant cooling,and their radiant cooling mechanism, analyzes the factors affecting the indoor thermal comfort. Taking experiment room applied of radiant cooling air conditioning technology as the research object, this paper builds simulation model of the room using Airpak,makes numerical simulation and contrastively analysis of the effect on the indoor thermal comfort for the two types of radiation cooling mode for ceiling radiant cooling and floor radiant cooling in three aspects of indoor vertical temperature difference, PMVPPD index and draft sensation. The results show that along the height direction of the room,the vertical temperature difference of roof radiant cooling is less than 3 ℃.But that of roof radiant cooling is too much,local thermal comfort requirements cant be met well; PMV value of the ceiling radiant cooling is fundamentally in -0.5 ~ + 0.5, the human body is closest to the best state of thermal comfort. But the floor radiant cooling only guarantees satisfactory PMV value around human body. When considering draft sensate,disapproval rating PD of two cooling patterns are less than 15%,which can meet the requirements of the human body for the thermal comfort of the hair dryer.
