Re: Water Routing for AC
There is no reason you can't run city water through your condenser. City water pressure will be more than enough. Dannyboy is correct in that too much water flow is less than ideal. It won't result in a loss of refrigerant flow through the metering device, but it could result in low evaporator pressure, and possible evaporator freeze up. This is no different from running cold ocean water through the heat exchanger, so presumably the manufacturer has some kind of head pressure control to deal with the problem. I wouldn't speculate more without knowing more about the design of the a/c make and model.
Just because you CAN use potable fresh water doesn't mean you should! That would be a colossal waste of water! Would you grab the hose, turn it on full, and just leave it running all day? That is what you would be doing!
You would be better off fixing the seawater system. Don't waste precious fresh water!
