Patent attributes
A vortex heat transfer device includes coaxial helical coil impellers operating at differing rotational speeds that are effective for mechanically establishing the vortices and allowing controlled heating and cooling between return and supply air streams. The outer impeller rotates at a multiple of the inner impeller speed, rapidly and compactly compressing the return air heating at the outer boundary and creating an inner boundary of low pressure of cooled air, which is reversely helically directed by the inner impeller for additional thermal separation. The conditioned air is delivered to the supply system. In the cooling mode, a discharge system removes heated air and condensed water vapor. The discharge system is thermostatically controlled for establish desired heating and/or cooling temperatures in a space to be conditioned.
