IMPROVEMENTS IN SYSTEM FOR AND METHOD OF ROTATING WHEELS IN ROTARY AIR-TO-AIR ENERGY RECOVERY AND DESICCANT DEHUMIDIFICATION SYSTEMS

摘要

A system for and method of rotating a transfer wheel (12) providing heat and/or moisture exchange between two counter-flowing air streams. The system comprises: a frame (16), a transfer wheel (12) including a transfer matrix (10) mounted and rotationally secured relative to the frame so that the wheel can rotate through tthe two counter-flowing air streams and heat and/or moisture can be transferred between the two counter-flowing air streams; and a first plurality of motor components fixedly mounted relative to the wheel so that components of the first plurality function as a rotor (84, 86) of a motor, and a second plurality of motor components fixedly mounted relative to the frame so that components of the second plurality function as a stator (74, 76) of a motor, wherein power supplied to motor components of the second plurality causes the transfer wheel to rotate through the two counter-flowing air streams.
