Lum, P C

A heat exchange apparatus is described comprising: an external rotor; an internal stator hermetically sealed within the rotor; an inertia device attached to the stator and able to resist movement of the stator so that a difference in speed between the stator and the rotor can be maintained on rotation of the rotor; a refrigerant; a rotary compressor for the refrigerant comprising a core attached to the stator, a wheel surrounding the stator, vanes mounted on the wheel and able to move with the rotor, a cylinder, eccentric to the vanes and attached to the stator, and oil able to form a liquid piston on rotation whereby relative rotation of the vanes and the cylinder compresses refrigerant as the volume between the wheel and the liquid piston decreases; a condenser for the compressed refrigerant; an evaporator to evaporate condensed refrigerant; means to return evaporated refrigerant to the compressor; and means to separate oil and maintain oil level for the liquid piston.
