<p>Disclosed is a system for conditioning a load using circulation of temperature controlled water where there is provided thermal storage means for holding varying volumes of water at different temperatures and the storage means comprises at least one tank having a constant cross-section between opposed vertical ends. A disc between the ends of the -tank separates the tank into first and second variable volume chambers and prevents blending of water at different -temperatures in the chambers. Conduits selectively feed water into one chamber while simultaneously removing water from the other chamber, the disc means moving in the tank in accordance with the feeding and withdrawal of water from the chambers whereby the volume of water in each chamber may vary but the total volume of water in the tank means is substantially constant. The disc is maintained substantially perpendicular to a vertical axis of the tank during its movement within the tank by a cable and pulley mechanism or vertical guides in association with the disc.</p> |
