Abstract
The seasonal heat storage tank is the most important component of the SDH system, which allows significant increase in the share of solar energy in heat supply in comparison with conventional solar systems with short-term accumulation of heat. The adverse impact of their investment sophistication on competitiveness may be compensated by the increased use. For example: Administrative cooperation with heat pump allows increasing the accumulation capacity of the seasonal heat storage tank. Such cooperetion causes the direct use of heating energy and the accumulation of cooling energy produced by heat punp in the final stage of the heating period. It can be used to remote cooling supplied buildings. Experimentation on mathematical models is possible to obtain valuable insights about the dynamics of the processes of charging and discharging in the seasonal storage tank and subsequently used in the design, implementation and operation.
