土壤热源热泵的研究(二)——地下温度场的计算机模拟

The Study of Ground Coupled Heat Pump System——Computer Analogue of the Underground Temperature Field

为了研究土壤热源热泵的性能,优化其供热、制冷系统的设计,进一步开发和利用土壤热,本文采用有限差分法对地下盘管工质温度和地下温度场进行了模拟计算。计算与实测结果基本相符。文中提出的计算机模拟程序可以用于土壤热泵地下盘管的优化设计。

In order to study the perforrnance of the ground coupled heat pump system, design the optimum systems for heating or cooling and further develop and use the ground source, this article uses the theory of fruite difference to simulate the medium temperature in the coils and underground temperature fields. The result of singulations is roughly the same as that of measurements, So, the computer analogue program can be used to optimize the ground coupled heat pump systems.
