摘　　要：通过对某毛细管辐射系统进行理论研究分析,确定了围护结构传热系数对毛细管辐射系统供冷能力的影响的变化规律,利用正交试验研究了墙体和外窗的传热系数及窗墙比对系统供冷能力的影响大小,最终确定窗墙比为主要影响因素,因此,在选用毛细管辐射系统供冷时,应优先考虑窗墙比对系统能耗的影响来确定系统的适应性。Through theoretical research,the influence law of the heat transfer coefficient of the envelope structure on the cooling capacity of the capillary radiation system is determined.Then the orthogonal test is used to study the influence of the wall,window and window wall on the cooling capacity of the system.The wall-to-window ratio is the main influencing factor.Under the condition that the window and wall performance parameters meet the specifications,the method of adjusting the window-to-wall ratio should be given priority to improve the cooling capacity of the capillary system.
