ABSTRACT:
A cold storage tank is mounted in a pit in the ground. An outer plastic sheet barrier lines the pit. A lining of incompressible insulating material lines the interior surface of the outer barrier. An inner plastic sheet barrier lines the interior surfaces of the insulation. A plurality of bags of fresh water are mounted inside of the inner barrier. Brine and gravel fills the inner barrier and the voids between said fresh water bags and covers the fresh water bags. An out-take pipe extends into the brine and is connected to a pump. A shallow tray is mounted above ground and the out-take pipe is connected to spray the brine onto the tray during freezing weather. An intake pipe is connected to drain the tray and return the cooled brine to the interior of the inner barrier. The brine surrounding the water bags is circulated through a heat exchanger for cooling air when required. Therefore the water in the bags will be frozen during freezing weather and cool air may be drawn out during warm weather for house or other cooling purposes.
