Units of Measure:
Chiller specifications come
in all sorts of units; some of the most common cooling
capacity specs are: KW, BTU/Hr, and Tons. Pressure could
be in bars, psi, or kilopascals. Pump output pressures
are often specified in 'feet-of-head'. We have tried to
stay with the most common user-friendly
units;
although, for temperatures we tend to standardize on °C.
If you do a lot of conversions between units, a very useful
program that will still leave you enough money to buy a chiller
is Convert,
by Josh Madison -- definitely worth a generous
donation.
Here are a few equations to get
you started if you have a calculator handy. Otherwise, give
us a call, we'd be happy to do the math for you.
- KW = BTU/Hr divided by 3.415
- BTU/Hr = Tons divided by 12,000
- °C = 5/9 x (°F-32)
- °F = (9/5 x °C) +32
