Abstract

Storage of energy is desirable for many purposes, such as heat energy produced by sunshine or by conventional energy sources during periods of off-peak demand. In the present case, heat energy is brought into a storage area by way of a "pillow" or quilted blanket-like device that has large storage space within itself and which, in addition, serves as a large heat-exchanger to impart its heat to other storage material within a container. The "pillow" or quilted blanket-like device is generally used to transfer heat into storage, to warm a swimming pool, for example. It could be used to extract heat from storage in cases where it is desired to store coolness. The low-cost materials used make it practical to have large quantity heat storage, large area heat-exchange surfaces, plus safety features such as protection for divers' heads, knees and elbows against concrete pool bottoms, plus decorative benefits such as beautiful pool bottoms or pool walls or both.

Dependent claims

In a pool or similar container of liquid having side and a bottom, heat exchanger--heat storage and pool-safety apparatus located adjacent to the bottom of the pool or similar container, said heat exchanger and heat storage apparatus comprising substantially liquid-tight upper and lower skin members substantially sealed to each other at limited areas in a quilted-like pattern defining areas for storage of warmed or cooled fluid and forming passages for flow or fluid through those areas, an inlet connection for introduction of warm or cool fluid to said areas for storage and circulation therethrough, an outlet connection for exit of fluid from said areas, said heat exchanger-heat storage--safety apparatus serving to reduce injuries to pool users, serving as heat storage apparatus when filled, and serving as a heat exchanger to impart heat to the liquid in the pool when the temperature of the fluid in said apparatus exceeds that in the pool, or to extract heat when the temperature of the fluid in said apparatus is lower than that in the pool.
