ABSTRACT:
The present invention uses a dessicant and a means of drying out or changing the system by the use of off-peak electric power releasing. The heat is then released as required during periods of peak electric power by the reintroduction of moisture. The system includes a source of air and a fan for circulating the air in a circulation system including an outgoing loop and return loop for the circulating air. Selectively operatable evaporator heat exchanger, air wetting apparatus, and air heating apparatus are disposed in the outgoing loop of the circulating air. A dessicant-containing enclosure used to provide heat storage, and having air inlet means thereinto from outgoing loop the circulating and an air outlet means therefrom to the return loop of the circulating air is disposed in the circulation system. The structure within the enclosure is such that there is a flow of air through a direct, unencumbered path out of contact with a major amount of the dessicant and by a secondary permeating flow through is dessicant. Selectively operable condenser heat exchanger apparatus is disposed in the return loop of the circulating air. Finally, selectively operatable air vanes are disposed in the return loop of the circulating air for (i) circulating air through, e.g. the force air furnace; or (ii) recirculating air through the circulating system.
