ABSTRACT:
Heat is transferred from a hot reservoir to an intermittent user such as a domestic appliance through an intermediate heat exchanger. Heat storing material maintains a substantially constant temperature at its phase transition point. When the intermittent user is operating, a heat exchange fluid such as NaK transfers heat from the heat storing material to a thermally degradable organic thermal exchange fluid through the intermediate heat exchanger to the intermittent user at substantially the temperature of the heat storing material. When the intermittent user is not operating, circulation of the fluids stops which allows the thermal exchange fluid to cool thereby reducing its thermal degradation. The heat storing material is selected for a high latent heat of phase transition, the heat exchange fluid is selected for thermal stability, and the thermal exchange fluid is selected for intermittent user needs such as mobility in a liquid phase at hot and cold temperatures.
