Abstract
A thermal energy system includes a first thermal energy system, a closed loop geothermal energy system, an intermediate heat pump thermally coupling the first thermal energy system with the geothermal energy system, and a second thermal energy system thermally connected to the geothermal energy system. The first and second thermal energy systems have opposite net thermal energy demands from the geothermal system. The geothermal energy system has first and second groups of borehole heat exchangers and each borehole heat exchanger contains a working fluid. Each borehole heat exchanger includes an elongated tube having a closed bottom end and first and second adjacent elongated conduits interconnected at the bottom end. Each group of borehole heat exchanger is selectively and alternatively connectable to the intermediate heat pump. The first thermal energy system may be a refrigeration system having condensers and the closed loop geothermal energy system may provide cooling of the condensers.
