Abstract :In this paper, optimization of the influence of the process parameters of ground source heat pump (GSHP) with the double U tube heat exchanger for space heating applications was performed . The coefficient of performance (COP sys ) in GSHP system was investigated during experimental measurements with various process parameters; space air inlet/outlet temperatures (T i,sa and T o,sa ) and soil inlet/outlet temperatures (T i,wa and T o,wa ). Taguchi method performed for obtained the optimum process conditions on the COP sys in GSHP system. Taguchi experimental design considered as L16 orthogonal array. The most influence of process parameter on the COP sys in GSHP system was evaluated by using analysis of variance (ANOVA) and signal/noise (S/N) ratio. The optimum process parameter was determined as A4B1C1D1 for COP sys in GSHP with ANOVA analysis. The optimum levels were computed as T i,sa at Level 1 (32 °C), the T o,sa at Level 2 (17°C), the T i,wa at Level 2 (6°C) and and the T o,wa at Level 1 (9°C). The most significant parameter on the COPsys for space heating applications of GSHP system were found as T i,sa and T o,sa with 48.4 %..Keywords : Taguchi method, ANOVA, ground source heat pump, COPsys, heating applications absorbent, refrigeration
