홈페이지논문 초록 (Abstract)
Among many new and renewable energy technologies, a ground source heat pump system has been declared as an energy efficient and an environmentally friendly system in meeting the thermal ener gy demands for residential and commercial applications. One major draw back for ground source heat pump system is the high initial cost and a relatively longer paybackperiod of the system. In this stu dy, a numerical analysis and an experimental investigation were c arried out on the effects of the heat pump performance and the buildin g load for a ground loop heat exchanger design. A decrease of heat pump unit fluid flow rate and an increment of COP for the heat pump unit r esulted in the reduction of the ground loop heat exchanger size in th e cooling mode. It was observed that reducing the peak load of build ing has the potential for reduction in the ground loop heat exchanger length. Matching the heat pump capacity with the building peak lo ad variation, a decrease of 40% in the cooling and heating peak load re sulted in a decrease of 44.5% and 69.2% in the total ground loop heat exchangers required in the cooling and heating mode, respectively.
