| 摘要: |
| 为研究住宅建筑中人员适应性调节及热舒适需求动态变化对其全年建筑供暖、供冷能耗影响,首先通过分析夏热冬冷地区典型城市-重庆住宅全年热环境调研数据（样本量2 151份）,揭示了居民全年舒适温度随室外温度呈S型变化特性,进而得到了基于人员适应性和动态热舒适的住宅全年供暖、供冷起止时间和动态温度设计参数。结合EnergyPlus建立了典型样本建筑模型（三人户,建筑面积105 m2）,分析了在执行JGJ134—2010《夏热冬冷地区居住建筑节能设计标准》基础上,基于人员热适应和温度动态调节下的住宅全年供暖、供冷节能潜力。模拟结果表明:住宅全年自然通风情况下室内热环境处于舒适区间（18～26 ℃）的比例仅占32.2%,采用传统供暖、供冷设定温度（18～26 ℃）下住宅全年舒适小时比例增加至62.87%,而基于人员适应性的供暖、供冷温度动态调节下舒适比例进一步增加5.45%；采用传统温度设计下住宅全年供暖、供冷单位面积能耗分别约为8.93、17.18 kWh/m2,相比采用温度动态调节下全年单位面积供暖、供冷能耗显著降低,分别为7.78、12.96 kWh/m2,节能量达20.6%,且供冷节能潜力更大。 |

| Abstract: |
| The effects of thermal adaption and dynamic demands for thermal comfort of occupants on heating and cooling energy consumption in residential buildings were explored. First, taking Chongqing as a typical city in the hot summer and cold winter zone, a thermal environment database for residences (sample size 2 151) was analyzed, and the S-shaped variation trend of annual comfort temperatures of occupants with outdoor temperatures was revealed. Then, the annual heating and cooling periods and the dynamic temperature settings for residences were determined based on the thermal adaption and dynamic comfort of occupants. Lastly, a typical reference residence was established by using EnergyPlus, with a family number of three and building area of 105 m2. According to the design requirements of the JGJ 134—2010 standard, the annual energy saving potential for heating and cooling in residential buildings was analyzed based on the thermal adaption and dynamic demands of occupants. Results show that under annually natural ventilation condition, only 32.2% of thermal environment was distributed in the comfort zone (18-26 ℃). With the traditional heating and cooling temperature design (18-26 ℃), the proportion was increased to 62.87%, and it was further increased by 5.45% under dynamic temperature settings. The annual energy consumptions per area for traditional heating and cooling temperature settings were nearly 8.93 kWh/m2 and 17.18 kWh/m2. While the dynamic temperature settings significantly reduced the annual energy consumptions for heating and cooling, with the values of 7.78 kWh/m2 and 12.96 kWh/m2 respectively. The annual energy saving was up to 20.6%, and the energy saving potential for cooling was greater. |
