B-41 Study on the Cooling and Heating System using Geothermal Energy by the Underground Aquifer Heat Exchanger : (Part5) Underground Heat Utilization Air-conditioning System in the Medical Welfare Institution in the Tohoku District

Abstract

In this report, we report a summary about underground heat utilization air-conditioning system which we installed in a medical welfare institution of Tohoku District. We performed a geological survey of the construction place and decided the execution method of the most suitable underground heat exchanger. And we measured COP of the heat pump and heat energy provided from the underground in the summer and the winter season and confirmed that a natural energy was used effectively.
