💧 Chilled Water Supply > Room Dew Point + 2.0°F (Preventing Ceiling Condensation)

Chilled Beam Condensation Prevention Calculator

Model room psychrometric dew point limits to prevent moisture condensation and ceiling water dripping from active and passive chilled beams under ASHRAE standards: calculate minimum Chilled Water Supply Temperature (CWST must remain strictly > Room Dew Point + 2.0°F to 3.0°F), automated dew point reset valves, and building automation controls margins.
