ABSTRACT:
A compact, self-contained highly efficient frictional air heating unit is provided which draws a flow of ambient air through an air inlet, frictionally heats the air, and discharges the air through an air outlet. The frictional air heating unit is utilized in a heating and cooling system for providing a source of heated air for heating, for powering an absorption type air conditioner system for cooling, and for heating water.
