Query
As per ECBC 2007, it is required to have VFD/ pony motors for cooling tower. However, for cooling towers that do not have a VFD, have a CPM-Cooling Plant manager. It has a provision that cooling tower fan speed is adjusted based on condensed water temperature. This eliminates the need to have a VFD.
Response
The project team is requested to share a technical specification sheet of cooling tower fans highlighting that the fan is capable of varying speed on command of CPM.
