摘　　要：毛细管席作为空调系统的辐射末端,得到逐步的重视和应用,但对于应用在闭式地表水源热泵系统中,作为地表水体的前端集热器的研究资料较少.建立毛细管简化的数学模型并通过大量数值计算,确定影响k值的各个参数,得出不同参数对k值的影响曲线,通过对影响曲线进行分析,区分出影响传热系数的主要、次要因素,对毛细管前端换热器的设计及应用提供理论基础.Capillary seats as the radiating end of the air-conditioning system come to be recognized and applied gradually,but the application of surface water source heat pump in a closed system,as the heat exchanger of surface water has less research data.This paper establishes the mathematical model of capillary simplified after much numerical calculation,determines the effect of each parameter of k value,and makes the curves of different parameters on the effect of kvalue.By the curve analysis,it also distinguishes the main influence factors of the heat transfer coefficient and provides the foundation for the application and design of the capillary front end heat exchanger.
