Abstract: Storage apparatus is used for storage of large quantities of heat, or for large quantities of "cold," and "dryness," or for simultaneous storage of heat and cold, and dryness. The heat, or cold, or both, may be produced during off-peak power periods, or by solar energy, or both. One example of utility of the invention is for use during the winter to store solar produced heat, or during the summer for cold storage produced by solar energy or by nighttime off-peak electric power. And, for springtime or autumn weather, the apparatus is usable to simultaneously store heat and cold. Then, for a chilly night or a cold spell, stored heat is available, or for a hot evening or a hot spell, stored coldness is available. Thus, the system for climate control of the home or other space may be switched from heating to air conditioning instantly.Zone heating and air conditioning are provided.

Abstract: For drying of crops and preserving of foods or other perishables or such a heat pump is used. The heat producing end or "Hot" side of the heat pump may be used to produce warm dry air for drying while the cold producing end or "Cold" side produces cool dry air for drying. The effect is to obtain much more drying per kilowatt hour of electricity used than if the electricity were used through resistance heating elements, as is now a common practice. Our precious energy is conserved and used much more efficiently.In addition to heat pump Hot and Cold drying, Solar Energy may also be used. That goes a step further in conserving our energy, during the Energy Crisis, and both approaches help to alleviate the Pollution Crisis by using less of our electrical or combustion produced energy, that must be produced by pollution creating equipment.A portion or all of the heat output, or cooling output, may be used for heating or cooling a home or other building.
