The innovation uses the disparity between dry and wet conditions of the air, by storing the dryness or wetness in a hygroscopic material. When the surrounding air is drier or wetter than the hygroscopic material, the potential energy difference between moisture in the air and that in the material can be used as a way of transporting heat from the material to the air and vice versa. A simple way this energy can be used is for heating and cooling of a building. For example, a large storage of adsorbing material can be dried in the hot summer, and allowed to re-adsorb water in the cold winter, thus gaining heat that can be used for domestic heating.

An air handling system is disclosed that includes an integral chilled water refrigeration system. The air handling system additionally includes a first coil section that provides cooling and a second coil section that provides heating. The second coil section and associated terminal units are in fluid communication with the first refrigeration system.
