If I increase the condenser water flow to a shell and tube refrigerant to water heat exchanger in a packaged air handling unit, how will that affect operation of the compressors? The plan under consideration is to change pump impellers so the condenser water flow rate is increased by 60% so that the existing (oversized) cooling towers will operate at the proper flow rate per manufacturer's recommendations - to get the proper pressure at the spray nozzles. How will this increased flow affect the operation of the compressors in a packaged air handler downstream?

"How will this increased flow affect the operation of the compressors in a packaged air handler downstream?"
The condensing pressure will decrease, the condensor water side temperature rise will decrease, the approach temperature will increase and if the flow rate is excessively excessive there could be a pitting/errosion problem created within the water side of the condensor.
