| 为研究两级新风除湿机与毛细管辐射系统联合运行特性，搭建了除湿机与毛细管辐射联合供热系统实验平台，测试了除湿
机单独运行的特性及除湿机与毛细管辐射系统联合运行时室内整体温度场响应特性。实验结果表明：两级新风除湿机连续运行720 min时，新风出风平均温度约
29.7 ℃，除湿机供热量约1 545 W；两级新风除湿机不同进水温度时，随着表面式换热器进水温度的提升，新风出风温度及换热量呈规律性增加；两级新风除湿机
与毛细管辐射系统联合运行时，除湿机供热量会减小约29.1%；垂直方向温度总体呈上升趋势，在人的活动范围内，室内垂直温差较小。该系统冬季供热时，能
减小室内垂直温差，提高人体舒适性。 |

| In order to study the combined performance of the two stage air dehumidifier and capillary radiation system, a dehumidifier and capillary radiant
combined heating system experimental platform was built. The performance characteristics of separate operation of dehumidifier and the overall temperature field response in the combined
operation of the dehumidifier and capillary radiation system were tested. The experimental results show that when the two stage fresh air dehumidifier continuously operates for 720 min,
the average temperature of the fresh air outlet is about 29.7 ℃, the heat supply of dehumidifier is about 1 545 W; when the two stage air dehumidifier has different inlet temperatures, with
the increase of the inlet water temperature of surface heat exchanger, the fresh air outlet temperature and heat exchange rate increase regularly; When the two stage fresh air dehumidifier
and the capillary radiation system operated together, the heat supply of the dehumidifier will decrease by about 29.1%; the temperature in the vertical direction will generally rise, and within
the range of human activities, the indoor vertical temperature difference is small. When the system is heating in winter, it can reduce the indoor vertical temperature difference and improve
human comfort. |
