摘要
为了考察低温热水地板辐射采暖在成都地区的应用效果,进行了地板辐射采暖和盘管对流采暖对比实验。结果表明,地板采暖空气竖向温、湿度梯度小,热量传递以辐射换热为主,辐射散热量占59.8%,在相同工况下,地板采暖的有效采暖时间是盘管采暖的2.7倍,地板采暖既舒适,也更经济节能。该对比实验研究为低温热水地板辐射采暖在夏热冬冷地区的推广应用提供了一定的依据。
In order to investigate the application effect of low temperature heating system in Chengdu,contrasting experiments have been carried out on floor radiation heating and fan-coil convection heating.The results indicate the temperature and humidity vertical gradient is very small when adopting floor heating,and the radiation heat transfer proportion is large,it＇s about 59.8%.The effective heating time of floor heating is 2.7 times longer than that of fan-coil heating under the same working condition.The floor radiation heating is comfort and economical saving energy,which provided the basis for its popularization and application in hot summer and cold winter area.
