Note:
1.
The heating capacity of the medium speed and low speed can be calculated by
the Speed Correction Factor.
2.
The heating capacity under different entering air temperature, calculating as
following example of MCW600C:
Step 1: Heating capacity of MCW600C is 38640Btu/h under below condition:
Water Flow 18 l/min, Water Temperature 140ºF (60ºC), Air Temperature
69.8ºF (21ºC)
Step 2: Variance of heating capacity when entering air temperature varies 1ºF:
38649 / (140 - 69.8) = 550.4Btu/ºF
Step 3: The heating capacity after modification under entering air temperature:
64.4ºF (18ºC) 550.4 x (140 - 64.4) = 41610.2Btu/h
