Abstract
The air conditioning system with a ground-coupled heat pump for a gravity meter room was designed by carrying out numerical simulations. The parameters of simulations were room temperature, a flow rate of heat extraction medium and the length of the Downhole Coaxial Heat Exchanger (DCHE). As a result of this investigation, the optimal values for room temperature, flow rate of heat extraction medium and the length of the DCHE were determined to be 18 degree C, 5 l/min and 12 m, respectively. The average COP (coefficient of performance) of the system over the first operation year was estimated to be 5.85 under the designed conditions. Also, it was shown that the system could be operated at stable performances over the long duration.
