If you would like help, feel free to give us a call. We do this all the time.
To size a chiller properly you
need to calculate the delta T between the inlet and outlet water
in temperature), and the rate of flow in gallons per minute
the delta T requires a thermocouple or thermometer. Check the
of the water inlet line and the water outlet line, and subtract
to compute how much heat the equipment is adding to the
Now that you have these two
you need to calculate how many BTU's (British Thermal Units)
puts off. Here is the formula:
Now that you have the BTUs,
compute the total Tons of cooling you need from a chiller. 1 Ton
is 12,000 BTU/hour so...
This is the size unit you
need. There may be other circumstances, like planning for
would lead you to buy a different size unit.
Other things to consider when choosing a Chiller:Make sure you compare apples to apples!
1. Is the chiller ARI Rated?
