❄️ Natural Gravity Convection Passive Beams (Cooling 120-250 BTU/hr-ft at ΔT 15°F)

Passive Chilled Beam Convection Calculator

Size silent, zero-fan-power passive chilled beams relying strictly on natural gravity convective air circulation: calculate cooling output per linear foot (120 to 250 BTU/hr-ft based on temperature difference ΔT between room air and chilled water supply), open ceiling void architecture, and high-efficiency sustainable HVAC contracting profits.
