Abstract
Aquifers may be suitable storage systems for both heat and cold. A supercomputer cooling system using groundwater has been successfully implemented at the Pawsey Australian Science Center. This study evaluates the possibilities of groundwater use for the cooling system of the Lomonosov supercomputer with a capacity of 2.8 MW to meet its needs for efficient summer cooling due to the insufficiently stable performance of the available air-cooling systems. The results of the experiment on injection of heated water into fractured limestone are presented. Based on the experiment interpretation, the heterogeneous block model (double porosity) of heat transfer has been chosen and its parameters are determined. The numerical-analytical program code for the interpretation of the field data of the experiment has been created. Several scenarios for the design of the cooling system are simulated. The simulation results have shown that nonstop operation of the designed system using the limestone aquifer would provide the maximum need for cooling the 2.8 MW supercomputer within a decade, while the required interval of operation in the summer period is 1 month.
