A potential customer has a core & shell building with packaged water source system (cooling only) connected to a constant water flow cooling tower. The cooling tower fan has variable speed. The internal untis are not part of the scope.
They want to change the system since it is old. One of my alternatives is to change the cooling tower for a new one and implement variable condenser water flow. One of my colleagues has suggested me that controlling variable condenser flow is not easy and will bring more problems than solutions. I am thinking to implement primary and secondary condenser loops. The primary will have constant water flow and will be connected to the cooling tower. The secondary loop is going to be a close loop with a heat exchange with the primary loop. The secondary loop will serve the packaged water source units and will have variable flow.
Does anyone have experience with this system implementation?
I am trying to simulate the two scenarios in Openstudio but I think it won’t give me the outputs that I am looking for.
Any comments will be appreciated.
