本文提出了一个相对简单的程序，用于对装有垂直U形管地下换热器的地源热泵系统进行年度逐小时模拟。在论文的第一部分中，我们回顾了经典的圆柱形热源解，并提出了一种包含负荷聚合的方法。然后，通过使用合适的方程求解器，可以迭代求解地面传热和热泵性能的耦合控制方程，以在相对较短的模拟时间内（在Pentium II 266 MHz机器上为20分钟）获得准确的年热泵能耗。 最后，研究表明，准确确定流体回路温度需要较大的负载聚合参数值。单位:双引用:研讨会论文，佐治亚州亚特兰大，2001年

This article proposes a relatively simple procedure to perform annual hour-by-hour simulations of ground-coupled heat pump systems equipped with vertical U-tube ground heat exchangers. In the first part of the paper, the classic cylindrical heat source solution is revisited, and a methodology to incorporate load aggregation is proposed. Then, it is shown that by using an appropriate equation solver, the coupled governing equations of ground heat transfer and heat pump performance can be solved iteratively to obtain accurate annual heat pump energy consumption in a relatively short simulation time (»20 minutes on a Pentium II 266 MHz machine). Finally, it is shown that an accurate determination of the fluid loop temperature requires a large value of the load aggregation parameter.Units: Dual
