Abstract
A chilling system is provided for chilling or cooling a supply of water or the like to a selected low temperature suitable for drinking and other uses. The chilling system includes a thermoelectric heat transfer module having a cold side for extracting heat energy from water contained in a reservoir, and a hot side for transferring the extracted heat energy to a circulating heat transfer fluid. In particular, the hot side of the module is in thermal communication with a manifold block through which a heat transfer fluid such as water is circulated by a pump. The pump circulates the heat transfer fluid through a heat exchanger for dissipating the extracted heat energy. In addition, the same pump drives an impeller within the reservoir to maintain the reservoir contents at a substantially uniform temperature level, and further may drive a cooling fan for providing a convective air flow across the heat exchanger.
