Abstract

A rotary heat regenerator wheel in which one or more performance characteristics, such as heat exchange efficiency and air flow rate, can be adjusted during manufacturing, during or after installation and/or after use of the regenerator. The wheel comprises removable segments having differing performance characteristics. One embodiment of the regenerator wheel includes segments containing both latent and sensible heat exchange material. Latent heat transfer efficiencies between those provided by heat regenerators having segments made only of sensible heat exchange material, and by regenerators having segments made only of latent heat exchange material, are achieved by adjusting the ratio of segments with exposed surface area of latent heat exchange material relative to segments having exposed surface area of the sensible heat exchange material. In another embodiment the air flow, pressure drop or surface area density of the wheel can be adjusted by using segments having different surface area densities.
