How is BTU converted into CFM? - Quora
WebFor heating driven applications, maximizing the BTU to CFM ratio maximizes efficiency while satisfying space temperature. Cambridge S-Series HTHV units are best suited for heating applications because they provide the maximum amount of BTUs per CFM. For airflow (make-up air) driven applications, consistent, tempered CFM is required to satisfy ... WebCooling mode: Air flow required: 400 CFM of air flow per Ton of A/C (1 Ton equals 12,000 BTU) Cooling mode: CFM of air delivery per square foot: 1 CFM of air is required to heat or cool 1 to 1.25 sq. ft. of floor area. Typical Manufacturer's Air Flow Rate CFM Specifications for HVAC equipment. Web24,000 BTUs ÷ 12,000 BTUs in 1 ton = 2 tons 400 CFM per ton = 800 CFM Room A = (2,000 BTUs ÷ 24,000 BTUs) 800 CFM Room A = 66.67 CFM TIP: Approximately 1 CFM of air is required to heat or cool 1 to 1.25 square feet of floor area. It takes closer to 2 CFMs to cool rooms with a lot of windows or direct sunlight. Figure the Friction Loss Rate tax bills cheshire ct
