Mathematical modeling of heat regime of underground heat accumulator

The article presents the thermal technical calculation of underground heat accumulator, which is used to prevent a sharp increase in air temperature hothouses on sunny days and accumulate solar energy. coefficient transfer by air-pipe pipe-soil boundary layers between 20-35 °C air-driven accumulator with help ventilator was calculated analytical method. mathematical model change time length during movement hot through pipe developed (based conditions). By applying submerged air, it possible 3 - 4,5 MJ, depending speed days.
