💨 ASHRAE 62.1 DOAS (Supply Air Dew Point 45°F-48°F), Total Latent Moisture Removal

DOAS Deep Dehumidification Calculator

Size 100% outdoor air Dedicated Outdoor Air Systems (DOAS) providing deep dehumidification for chilled beam and VRF buildings under ASHRAE 62.1: calculate total latent moisture removal (Lbs water/hr decoupling latent loads from space sensible cooling by delivering fresh air at 45°F to 48°F dew point), energy recovery wheels (sensible + enthalpy), and DOAS margins.
