How to Correctly Size a Water Chiller

How to Correctly Size a Water Chiller

BTU/ hour = 500 x GPM x Temperature Difference (delta T) Repeat this for all the equipment you have, and add up the total BTUs. Now that you have the BTUs, compute the total tons of cooling you need from a chiller. For example, 1 Ton of cooling is 12,000 BTU/hour s.

Dec 29, 2018 This converts the volumetric flow rate to a mass flow rate, which is measured in pounds of water per hour. With this example: 3,900 x 500 = 1,950,000. This answer is the chiller's capacity measured in BTUs per hour. Divide your answer by 12,000: 1,950,000 / 12,000 = 162.5. This is the chiller's capacity in tons.
