Dear all,
I would like to know the proper way to calculate the heat load when we are given data such as total sensible heat (kW) from equipment and human. Will appreciate if you guys help me calculate one example from the data below..
Example:
Building: Wax Plant
Location: Field Auxiliary Room
Area = 72.5 m2
Ceiling Height = 3.7 m
Volume: 268 m3
Cooling Density = 598 W/m3
Total Cooling = 43.3 kW
Total Sensible Heat = 30.4 kW
Air Change/hr = 26
Cooling air = 6,942 CMH
By using the basic rule of thumb, I get capacity factor of 190 (Cooling Capacity/Area in ft2)
Is there any proper way to get a more precise calculation, rather than using the rule of thumb method?
Thanks
