地源热泵系统在建筑供暖和制冷方面越来越重要。为了评估其性能，需要详细的模拟模型，包括短期（计算热泵的瞬时性能系数）和长期（计算地温变化）精度。阶跃响应采用短期响应模型和长期响应模型的组合进行计算，短期响应模型考虑了热载体流体、水泥浆和紧邻地面的瞬态热传递，长期响应模型计算钻孔相互作用。 这两种模型的最新技术都是从广泛的文献综述中选择的。此外，还采用了一种聚合方法来加快计算速度。验证结果显示了良好的结果和非常高的计算效率。引文:ASHRAE论文CD:2014 ASHRAE年会，华盛顿州西雅图

Ground coupled heat pump systems are gaining importance for heating and cooling of buildings. To assess their performance, detailed simulation models are required with both short-term (to calculate the instantaneous coefficient of performance of the heat pump) and long-term (to calculate the ground temperature evolution) accuracy. A step response is calculated using a combination of a short-term response model which takes into account the transient heat transfer in the heat carrier fluid, the grout and the immediately surrounding ground, and a long-term response model which calculates the boreholes interactions. The state-of-the-art of both models has been chosen from an extensive literature review. Moreover, an aggregation method is implemented to speed up the calculations. Validation shows good results and very high computational efficiency.
