A thermal storage method for utilizing the large-scale heat capacity aquifers was investigated experimentally. Two wells, A and B, were prepared to serve as thermal reservoirs. In the winter, the underground water was pumped up from A well and sprayed over the snow-capped rooftop to melt away, and then it was injected into the B well. A supply of cold water, remaining cool inthe aquifer, was pumped up from B well and used for air conditioning in summer. The experimental results showed that about 30% of the stored heat, both hot and cold, could be recovered. The C.O.P. reached up to 20, if the system is regarded as an annual cooling system.
