d Allowable water temperature range is 100°F to 200°F. Allowable indoor air temperature range is 40°F to 100°F. If temperatures below freezing
are expected, provisions should be made to either drain the unit heater coil or utilize a continually circulating glycol solution.
Useful Formulas:
Air Temperature Rise
The air temperature rise can be calculated by the following formula:
Btu/Hr
Air Temp Rise =
1.08 x CFM
Example:
What is the Air Temp Rise for a model size 45 unit, operating at high speed, 140°F entering water, 3 GPM flow rate?
From Table 9.1, the output is 33,200 Btu/Hr. The air temperature rise, per the formula above, is:
33,200 Btu/Hr
Air Temp Rise =
1.08 x 710CFM
= 43°F
Final Air Temperature
The final discharge air temperature can be calculated by the following formula:
Final Air Temperature = Air Temperature Rise + Entering Air Temperature
Example:
What is the Final Air Temperature for the previous example?
The air temperature rise was previously calculated to be 43°F. The final air temperature, per the formula above, is:
Final Air Temperature = 43°F + 60°F = 103°F
