Redesign and Replacement of Air Handling System

Under this project, 36 new custom-designed AHUs, designed for 80% return air, were installed. This allows the facility to operate using 22% less airflow and 60% less outside air, while still meeting all codes, indoor air quality, and comfort condition requirements. All of the new units include premium-efficiency electric motors and several areas now have enthalpy recovery wheels that recover both sensible and latent energy from the exhaust air stream. The test cell units were also built with special bypass dampers to minimize simultaneous heating and cooling. Five of the test cell units also include an auxiliary cooling system using indirect evaporative cooling and heat pipes. This effectively treats the high-temperature return air caused by heavy engine testing. As a result of this measure, heating and cooling system capacity and overall energy use for dehumidification and reheating during the cooling season, as well as heating, humidifying, and reheating during the heating season, has been minimized.
