| 为了提高夏热冬冷地区供暖房间室内热舒适性，本文利用室内宜居环境技术研究测试平台，通过实 测散热器系统(供回水温 45 ℃/40 ℃)与空调系统供暖房间各点空气温度，对比分析两种不同供暖方式下室内温 度分布特征，研究得出：采用供回水温 45 ℃/40 ℃的低温热水散热器连续供暖，房间各点平均温度保持在18.9～23.4 ℃之间，达到夏热冬冷地区热用户室内温度需求；与空调热风供暖相比，低温散热器供暖可使房间 内各点逐时温度波幅小于 1 ℃，温度波动更平缓，且低温散热器供暖房间室内水平温度分布更稳定，垂直温 度梯度变小，温度分布更均匀。结论为夏热冬冷地区供暖方案的优化设计和室内热舒适度的改善提供了参考。 |

| In order to improve the indoor thermal comfort of the heating room in hot summer and cold winter area，this
paper makes use of indoor livable environment technology research and test platform，through the measured radiator system
(supply and return water temperature 45℃/40℃) and air-conditioning system heating room air temperature，comparative
analysis of the indoor temperature distribution characteristics of two different heating methods，the study concluded：
the supply and return water temperature 45℃/40℃ low temperature hot water radiator continuous heating，the average temperature
at each point in the room was maintained at 18.9~23.4℃. Compared with air-conditioning hot-air heating，lowtemperature
radiator heating can make every point within the room temperature fluctuations of less than 1℃，temperature
fluctuations more gentle，and low-temperature radiator heating room indoor. The horizontal temperature distribution is more
stable，the vertical temperature gradient is smaller and the temperature distribution is more uniform. The conclusions provide
the reference for the optimal design and the improvement of indoor thermal comfort of heating scheme in hot summer
and cold winter area. |
