摘　　要：为了充分了解夏热冬冷地区地面辐射供暖与散热器供暖的差异性,建立空气源热泵+地面辐射/散热器供暖实验平台,测试室内空气温湿度、围护结构壁面温度、黑球温度等参数,分析两者供暖差异性及形成原因。结果表明:两者差异主要表现在散热器供暖室内空气升温快、热舒适等级为Ⅱ级,地面辐射供暖热舒适等级为Ⅰ级,这是由于地面辐射供暖的蓄热量比散热器供暖大;两者室内平均辐射温度差异不大,但由于热水管与地板间的保温层不可能完全绝热,地面辐射供暖用户的地板与下层房间天花板温差明显高于散热器供暖的房间,地面辐射供暖传热损失大。In order to fully understand the difference between radiant floor heating and radiator heating in hot summer and cold winter areas,an air source heat pump+radiant floor/radiator heating experiment platform is established to test indoor air temperature and humidity,wall temperature of enclosure structure,black bulb temperature and other parameters.The heating differences between the two and the reasons for their formation are analyzed.The results show that the difference is mainly manifested in the rapid temperature rise of the indoor air in the radiator heating,the thermal comfort level is level II,and the thermal comfort level of radiant floor heating is level I.This is because the heat storage of radiant floor heating is larger than that of radiator heating.There is little difference in the average indoor radiant temperature between the two.However,because the thermal insulation layer between the hot water pipe and the floor can not be completely insulated,the temperature between the floor and the ceiling of the lower room of the radiant floor heating user is significantly higher than the room heated by the radiator,and the heat transfer loss is large.
