Add Energy Recovery to Any HVAC System

This simple unit was built for an elementary school in Virginia. Consisting of just a flat plate heat exchanger, face–&–bypass damper and actuator, cabinet, and simple analog damper controls, it complements the primary heating and cooling equipment provided by others. This simple design makes it possible to add energy recovery to any new or existing HVAC system and allows the customer and engineer the flexibility to use other equipment from any desired manufacturer—and in this case, the pay off was big. The XeteX unit pre-warms the winter air from 10 °F to 47 °F, and in summer it pre-cools the air from 95 °F to 83 °F. This dramatically reduces the load on the primary heating and cooling equipment and results in savings for the building owner every month of the year.
