LONG-TERM COLD ENERGY STORAGE IN AQUIFER FOR AIR CONDITIONING IN BUILDINGS.

Author(s) : HOVE J. van, LOON L. van

Summary

A COLD ENERGY STORAGE SYSTEM REQUIRES A SOIL STRUCTURE THAT IS SUITED TO THE EXTRACTION AND INJECTION OF WATER. THE SYSTEM OPERATES ACCORDING TO THE PRINCIPLE OF < AQUIFER THERMAL ENERGY STORAGE >. A WELL-PAIR IS USED FOR THIS PURPOSE: A SO-CALLED < WARM > WELL AND A SO-CALLED < COLD > WELL. GROUNDWATER IS PUMPED BACK AND FORTH BETWEEN THE TWO VIA THE AIR CONDITIONER'S HEAT EXCHANGER. THE COLD STORAGE SYSTEM IS DIFFERENT FROM TRADITIONAL AIR-CONDITIONING SYSTEMS ; IT HAS WELLS INSTEAD OF COOLING MACHINES, THE HEAT EXCHANGER MUST HAVE A LARGER SURFACE, AND THE METHOD OF CONTROL AND THE CHOICE OF MATERIALS ARE ALSO DIFFERENT. THE SYSTEM REQUIRES A RATHER COMPLICATED CALCULATION TECHNIQUE. A NOTABLE SAVING OF ENERGY MAKES THE SYSTEM ECONOMICALLY AND ECOLOGICALLY ATTRACTIVE. EXPERIENCE WITH A DEMONSTRATION PROJECT IN AN EXISTING BUILDING INDICATES THAT THE TECHNICAL PRINCIPLES CAN BE ACHIEVED IN PRACTICE. AN EVALUATION OF THE TS.
