Abstract
Apparatus for heating or cooling ambient air in the form of a temperature controlling propeller having a plurality of blades arranged around a rotatable hub, the blades carrying cells containing a heat retaining material. The cells are mounted in openings provided in the blades and retained therein. A thermometer may be mounted on the hub to monitor air temperature. The propeller is heated or chilled prior to mounting on a driven shaft. When the propeller is rotated by the shaft, it simultaneously circulates and heats or cools the surrounding air as desired.
