Abstract

The research results regarding to the influence on the efficiency of ground heat accumulators of thermophysical characteristics of the soil mass center are analyzed. It is determined that for the different types of soils there are existed maximum values of humidity at which their thermophysical properties are the optimal. The construction of ground heat accumulator, which provides support of optimal humidity of soil parts, separated from natural soil mass center with small moisture content by waterproof screen from ground-cement piles is proposed. The accumulator will increase the use of thermal efficiency of daily atmospheric air thermal disequilibrium in the systems of heat and cold supply, at the same time the surface of the heat exchange elements will be 2,5 times smaller in comparison with the required surface when the elements are placed directly in «dry» (low water content) soil.
