The present research work focuses on the optimization of the ground heat exchanger of the Ground source heat pump system for heating application based on exergetic analysis using the Taguchi method. For this work, we select four influencing factors such as the mass flow rate of water (A), the specific heat of water (B), inlet temperature (C) of water to and outlet temperature of water (D) from the ground heat exchanger at three levels. An L9 orthogonal array was selected for experimental trials and in each trial, we calculate the exergy destruction for the ground heat exchanger, thereafter using statistical software Minitab, we get signal to noise ratios based on smaller is better criterion. After analyzing the response table of Taguchi results, we get the optimum level of all the factors. The ANOVA technique was also applied for getting the most significant factors which affect the output results by calculating the percentage contribution of each factor. According to our results, the best combination of all the four factors for exergetic destruction of the ground heat exchanger was A3B1C1D3 and the most influencing factor was inlet water temperature with a contribution factor of 56.03%.

目前的研究工作集中在基于田口法的高能分析的基础上，对供热应用的地源热泵系统的地热交换器进行了优化。在这项工作中，我们从地热中选择四个影响因素，例如水的质量流量（A），水的比热（B），水的入口温度（C）和水的出口温度（D）。交换器在三个层次上。选择L9正交阵列进行实验，在每个实验中，我们计算地面热交换器的火用破坏，然后使用Minitab统计软件，根据更好的标准获得信噪比。在分析田口结果的响应表后，我们得到了所有因素的最佳水平。通过计算每个因素的百分比贡献，ANOVA技术还用于获得影响输出结果的最重要因素。根据我们的研究结果，对地面热交换器进行彻底破坏的所有四个因素的最佳组合是A3B1C1D3，而影响最大的因素是进水温度，其贡献率为56.03％。
