Case Study:

Georgia Tech's HVAC service contractor finds success with modular replacement ERV wheels

When the original ERV wheels at a campus dormitory could no longer be cleaned or serviced, replacing them was the only choice. But a matching replacement would be difficult due to limited access to the mechanical room.

A creative solution was found in Airxchange's replacement wheel design, which allowed them to be carried into the mechanical room in sections and then assembled in place.

HVAC Trends:

The unnecessary cost of designing for low cross leakage

New study measures economic impact of increased building ventilation

Efforts to design for an exhaust air transfer ratio (EATR) of 0% frequently increase energy costs without providing any meaningful improvement in IAQ. In most applications, the optimal EATR selection point for energy recovery wheels is in the range of 2-4% - a rate that balances the tradeoffs between IAQ, energy costs, and installation costs.

Understanding these tradeoffs allows engineers, equipment manufacturers, and building operators the most flexibility to meet building performance objectives over a wide range of operating conditions. Airxchange: Cross Leakage Efficiency

Airxchange engineer Samantha Alleva presents the tradeoffs in a peer reviewed article published in the November, 2017 issue of ASHRAE Journal.
