THERMAL ACCUMULATORS AND THE DIFFERENCE IN HEAT STORAGE

Abstract

In solar thermal and cooling supply schemes, heat storage-based accumulators (such as water, gravel, crushed stones, and others) are widely used. In some cases, heat accumulation is achieved by heating a water layer surrounding stones. At the same time, the working materials used in the above-mentioned heat accumulators, in desert and semi-desert areas, for supplying low-power consumers with hot water, have certain disadvantages, mainly of an economic nature. These include the limited availability of drinking water and the high cost of electricity and thermal energy used to accelerate the process (such as pumps, ventilators, large containers, etc.).
