分析了影响地埋管换热器系统运行效果的常见设计因素,将单因素敏感性分析方法引入到设计风险控制中,为提高设计成果的准确性和可靠性创造条件。以某地源热泵项目为例,介绍了该方法的具体应用,通过对地埋管换热器系统设计中用到的主要设计参数进行单因素敏感性分析,探讨了各不确定因素对进出水平均温度的影响程度,为控制设计风险指明了方向。
The common design factors that affect the operation effect of ground heat exchanger system are analyzed. The single factor sensitivity analysis method is introduced into the design risk control to create the conditions for improving the accuracy and reliability of design results. Taking a ground source heat pump project as an example, the specific application of the method is introduced. Through the single factor sensitivity analysis of the main design parameters used in the design of ground tube heat exchanger system, this paper discusses the influence of various uncertainties on the entry and exit levels The influence of the average temperature indicates the direction for controlling the design risk.
