Chiller Tonnage Sizing & Capacity Calculator | Cold Shot

Oversize the chiller by 20% Ideal Size in Tons = Tons x 1.2; You have the ideal size for your needs; For example, what size chiller is required to cool 40GPM from 70°F to 58°F??T°F = 70°F - 58°F = 12°F; BTU/hr. = 40gpm x 60 x 8.33 x 12°F = 239,904 BTU/hr. Oversize the chiller = 19.992 x 1.2 = 23.9904; A 23.9904 or 25-Ton chiller is required

Multivariable regression analysis to assess energy

28/03/2018 · For example, referring to a Carrier 3-ton heat pump at 1200 CFM (400 CFM/ton, nominal), 63 entering wet bulb (75F dry bulb @ 50% RH) and 95F outdoor: If airflow drops to 1050 CFM (350 CFM/ton), total capacity will drop by 2.1%, whereas sensible capacity will drop by 6.5% and latent capacity will increase by 18.5%!
