🌀 DOAS Enthalpy Desiccant Wheel (75% Effectiveness), Dehumidification CFM

Dedicated Outdoor Air System (DOAS) Calculator

Size 100% Dedicated Outdoor Air Systems (DOAS) paired with chilled beams or VRF: calculate ventilation outdoor air volume (CFM), sensible and latent cooling loads (handling 100% of space moisture load to maintain <50% RH), total energy recovery enthalpy wheel effectiveness (75%), and mechanical engineering profits.
