Building Retrofitted with Air-Duct Delivery System for Roof-top Units

July 31, 2015 By Linda Hardesty

XChanger Companies has been awarded its second grant from the University of Maryland’s Center for Environmental Energy Engineering. The grant money will be used to install another of its HVAC airflow technology systems in a second commercial building. The first grant the company received was used in the Holmatro USA commercial manufacturing facility in Glen Burnie, Maryland.

The XChanger system is an airflow device that works with any source of heat or conditioned forced air from boilers, chillers, furnaces or heat pumps. The device is custom built and custom installed to existing HVAC systems in existing facilities or new construction. An energy audit and review of current operating costs provides the baseline information needed to start the comparison process. This data is then modeled to demonstrate the savings potential of the XChanger device in each community application.

The XChanger technology is an extended duct air delivery system for roof-top unit applications. It can either strengthen or weaken the temperature stratification created in the conditioned space as needed in order to provide an improved thermal comport to occupants while saving energy.

The Center for Environmental Energy Engineering focuses on research and education on air-conditioning, refrigeration and heat pumping and integrated cooling heating and power systems.
