FIELD: power engineering. SUBSTANCE: device has well with heat exchange unit mounted thereon. The well is produced in water-bearing layer filled with water. The well is connected to excitation device generating pressure oscillations accompanied by periodical water movement direction for the opposite one with rock integrity being retained in zone of pumping out. EFFECT: avoided ground undermining; enhanced effectiveness and ecological safety of heat accumulation process. 1 dwg |
