In this study, NR GT 101 (water-to-water Ground source heat pump unit) and NR GT 102 (water-to-air Ground source heat pump unit) related with ISO and ARI guideline were introduced and researched. GSHPs testing was performed by NR GT 101, 102 and analyzed performance factors. Test result, Energy Efficiency Ratio and Coefficient of performance factor of GSHPs were relatively low at an average value rather than Certification.
