Abstract
A temperature conditioning system employing an ejector-type compressor and a refrigerant selected for operation at the limited operating temperatures of a heat energy collection and storage apparatus. Improved performance may be achieved by employing a two-tank storage system having a control circuit for supplying heat transfer medium from the hotter of the tanks for return to the cooler.
