ABSTRACT:
Water recovery apparatus having a main heat reservoir and an adsorbent material, the apparatus operable in an adsorbent phase of operation for adsorption of water from the atmosphere into the adsorbent material using relatively humid, cool air and operable in a desorption phase of operation for the desorption of water therefrom using relatively drier, warmer air, the apparatus comprising an auxiliary heat reservoir, means for connecting the auxiliary heat reservoir in a first air flow path downstream of the main heat reservoir at the end of a desorption phase of operation, whereby said auxiliary heat reservoir stores energy from the main heat reservoir, and means for connecting the auxiliary heat reservoir in a second air flow path upstream of the main heat reservoir during the next succeeding desorption phase of operation whereby the auxiliary heat reservoir transfers heat energy stored therein to the air passing therethrough for pre-heating the air prior to passage through the adsorbent material and main heat reservoir.
