兼顾节能效益的建筑室内热舒适温度调整研究

各气候区居民对室内热舒适的要求随其穿着习惯、对热环境的适应能力等而异,采暖或制冷温度应有所差别,然而现有建筑节能设计标准按统一标准提供室温控制建议。采用ISO7730的PMV热舒适模型分析各气候区的合理参数,计算得到室内热舒适温度,并通过与实测值比较验证理论计算的合理性;在此基础上,分别计算按既有统一室温建议与热舒适温度控温的热舒适性和能耗,提出冬季适当提高采暖温度以提升热舒适度、夏季适当提高制冷温度以实现热舒适度和节能双赢的调整建议。

Study on Indoor Thermal Comfort Temperature Adjustment with Consideration of Energy-saving Benefit

Residents of each climate zone have different requirements for indoor thermal comfort due to different wearing habits and the ability to adapt to the thermal environment,but the existing standards offer the same room temperature control suggestions. The paper uses the PMV thermal comfort model of ISO7730 to analyze the reasonable parameters of each climate zone,calculate the indoor thermal comfort temperature,and verify the rationality of theoretical calculation by comparison with the measured values. On this basis,calculates thermal comfort and energy consumption by existing room temperature suggestions and thermal comfort temperature control,finds that increase heating temperature in winter to improve the thermal comfort and increase refrigeration temperature in summer to achieve the thermal comfort are win-win situation.
