Air-to-Air Exchangers

When is it cost effective to include air-to-air energy exchange? Most HVAC engineers know that air-to-air devices for heat and moisture exchange (e.g., heat exchangers and energy wheels) can be used to significantly reduce utility cooling and heating loads and costs. However, engineers often are not sure how the devices function and how they can be assembled and sized for an HVAC system for maximum savings. In addition, what energy savings can be expected and will these devices increase or decrease the total equipment cost?
