WebTo determine CFM, first, find the size of your heating or cooling unit in tons. Then, multiply this number by the average output of an HVAC unit, or 400. Next, divide this number by the overall square footage of your home. This calculation gives you the multiplier to determine the CFM for all your rooms. WebJun 24, 2024 · This coil condition 1) is a possible statepoint to achieve with the cooling coil entering conditions and 2) would balance the sensible load and latent loads with the same airflow. Sensible: 12000 btuh = 1.085 x 510 cfm x (75-53.3°F). Latent: 2400 btuh = 0.69 x 510 cfm x (65.6-58.8 gr/lb).

To determine the future cooling needs of this data closet, we multiply the total IT heat output by 1.5, so 12,036 W x 1.5 = 18,054 W. Adding this new number to the existing ones gives us a future total cooling requirement of 37,017.412 W or 10.5 t of cooling. barata logo
