Bar chart comparing energy use of a conventional fixed-capacity dedicated outdoor air system, always 100 per cent, against an LC DOAS falling to 95, 66, 45, 28 and 16 per cent as active ventilation drops from 100 to 20 per cent

BREAKTHROUGH ENERGY SAVINGS VS. CONVENTIONAL FIXED CAPACITY DOAS

Bar chart comparing energy use of a conventional fixed-capacity dedicated outdoor air system, always 100 per cent, against an LC DOAS falling to 95, 66, 45, 28 and 16 per cent as active ventilation drops from 100 to 20 per cent

Florida Solar Energy Center conducted a study documenting the Linear Capacity achieved greater than 50% energy savings versus conventionally fixed capacity DOAS. Regarding this new variable capacity DOAS technology, they wrote “Addison HVAC has developed an exclusive DOAS package design that uses a novel combination of variable refrigerant flow (VRF), variable air flow (VAF), and Active Coil Exposure™. This design results in energy-efficient ventilation with the potential to meet diverse requirements without over- or under-ventilating”.
