Heating cfm
Web17 de abr. de 2024 · The formula for calculating BTU loss or gain in converting CFM to BTU is temperature difference times actual CFM leakage times 1.08 equals BTU loss or gain. CFM is the actual cubic feet of air volume per minute pushed through the HVAC unit. BTU is the British thermal unit of heat removed from the room by the HVAC unit. WebIn addition, electric heat has no odor, flame or carbon monoxide. The high CFM and low temperature rise are also key features to make the PKB Platinum the best solution for temporary large capacity heating applications. Spiral finned steel elements and high CFM ensure even air distribution producing cooler element operation, prolonging heater life.
