decompression cycle is governed by the air-pressure loss, as well as heat loss by conduction to the concrete liner and surrounding … rock. For a sufficiently tight system, i.e., for a concrete permeability of less than 1×10−18m2, heat loss by heat … such a case, almost all the heat loss during compression is gained back during subsequent decompression. Finally, our …
