AbstractThe seasonal storage of coolness in the ground, in a rock bed, in aquafers, in the form of ice (in both covered and uncovered ice ponds), and in the form of frozen soil were studied. A storage capacity of 10 TJ for the aquafer and 1 TJ for all others were considered. The technical and economic feasibilities of each system were considered for each of the six Canadian cities having different climatological conditions. Technically, all systems, with the exception of gradual ice production and soil freezing in Vancouver and Victoria, are feasible anywhere in Canada. The economic analysis which was based on certain assumptions regarding the costs of land, excavation, construction, insulation, equipment, etc. showed that storage of coolness in aquafers, in gradual production of ice, and in soil freezing is less expensive than conventional water vapour compression refrigeration systems when the cost of land is not included. With a land price of $150/m² only the aquafer system is cheaper. The report recommends that experimental studies on storing coolness in aquafers, frozen soil, and ice be carried out.
