PHE & Cooling Tower Requirement for Genset 3

[simangunsong]

Hi all..

I have no idea how to calculate PHE flow and temperature for Cooling tower. The objective are selecting PHE and cooling tower for genset for my design..
If :
- Genset capacity : 2000 kVA
- Genset heat rejection to coolant : 60816 BTU/min
- Coolant Flow : 436 GPM
- Standard Thermostat (modulating) Range Degree F : 160~185
- Maximum Coolant Temperature at Engine Outlet Degree F : 208
- Genset unit without Radiator.

As Formula : Q = mc(Delta)T
and result, Delta T = 5,123x10^-17 'C

But, as I know, difference temperature from genset and from Cooling tower is not 1.

Thank you for your help.

Hi all..

I am sorry for late response..

@Littleinch
I solved it with the help from the generator specialist, he calculate and select the Plate Heat Exhanger based on our requirement data.
