本研究的目的是调查在中国北京的采暖季节，老年人的家庭室内热环境。调查时间为2016年12月至2017年2月，涉及城乡房屋。通过主观调查和客观测量，对供暖设备、老年人室内着装和热感觉以及室内物理参数进行分析。结果表明，不同类型的供暖系统/设备在城市和农村的住宅中使用。总体来看，农村房屋冬季供暖持续时间比城市房屋长。在室内空气温度方面，城市老年人比农村老年人经历了更温暖和更舒适的热环境。在调查期间，城市住宅起居室/老人卧室的平均空气温度为21.9 +/- 2.2 ℃/21.5 +/- 2.8 ℃，明显高于农村住宅的16.1 +/- 3.5 ℃/14.6 +/- 3.3 ℃。此外，农村老年人由于频繁出入，通常会遇到室内和室外之间的较大温度台阶。尽管农村房屋的空气温度相对较低，但老年人报告室内热环境是可以接受的，因为农村地区的老年人在冬季在室内穿较厚的衣服。这也表明农村老年人的可接受温度低于城市老年人。值得注意的是，可接受的温度可能无法满足老年人长期的身体健康要求。需要更多的研究，以确定合理的温度，热舒适和健康的老年人。
This study intends to investigate indoor thermal environment in homes with elderly people during heating season in Beijing, China. The investigation was performed from December 2016 to February 2017, involving both urban and rural houses. Heating equipment, indoor clothing and thermal sensation of the elderly, and indoor physical parameters were analyzed through subjective surveys and objective measurements. Results show that different types of heating systems/devices are used in urban and rural houses. Overall, the heating duration of rural houses is longer than that of urban houses in winter. In terms of indoor air temperature, urban elderly people experienced warmer and steadier thermal environments than rural elderly people. During the investigation, the average air temperature in living rooms/elderly people's bedrooms of urban houses was 21.9 +/- 2.2 degrees C/21.5 +/- 2.8 degrees C, significantly higher than 16.1 +/- 3.5 degrees C/14.6 +/- 3.3 degrees C of rural houses. Additionally, rural elderly people usually encountered a large temperature step between indoors and outdoors, due to frequent exit and entry. Despite of relatively low air temperatures in rural houses, the elderly reported that the indoor thermal environment was acceptable, since the elderly in rural areas wear thicker clothes indoors in winter. This also indicated the acceptable temperature for elderly people in rural areas was lower than that for elderly people in urban areas. It is noted that the acceptable temperature may not satisfy long-term physical health requirements of the elderly. More studies are needed to determine reasonable temperature for both thermal comfort and health of the elderly.
