How can we select the size of cooling tower required for 1000 KVA DG set?

To select the size of a cooling tower for a 1000 KVA diesel generator (DG) set, first determine the heat rejection requirement, which is typically around 10-15% of the DG's output power. For a 1000 KVA DG set, the heat rejection would be approximately 100-150 kW. Next, consider the cooling water flow rate and the temperature difference between the inlet and outlet water to determine the cooling tower capacity. Finally, consult manufacturer specifications and guidelines to choose a cooling tower that can handle the calculated heat load efficiently.
