Abstract: The objective of this study is to show the operation method of geothermal heat pump(GHP) system to improve energy efficiency through the TRNSYS simulation. The case study building is a hospital with a GHP total capacity of 530RT. Existing operation method of GHP is to set temperature of supply chilled water to 7℃ in summer. This paper proposed two operation methods: (1) GHP control according to COP(coefficient of performance), (2) GHP control according to indoor temperature, (3) GHP control according to indoor temperature.The result of the simulation is that proposed operation method was less consuming energy than existing operation method. (3) GHP control according to indoor temperature. The result of the simulation is that proposed operation method was less consuming energy than existing operation method.
