Abstract
A water savings system and method for reducing the amount of water needed for adiabatic cooling including the use of a softener and a reverse osmosis device, in which tap water, softened if necessary, is delivered to a reverse osmosis device and softened water alone, reverse osmosis reject water, or softened water combined with reverse osmosis reject water is delivered to spray nozzles for cooling, and reverse osmosis pure water is stored and used periodically to flush the coils to inhibit and/or prevent corrosion from dissolved salts and other solids in the spray water.
Claims16
A water supply system for delivering cooling water to a heat exchanger, comprising:
- a water softener configured to receive water from a water source;
- a reverse osmosis device configured to receive softened water from said water softener;
- an RO-permeate storage tank configured to receive RO-permeate water from said reverse osmosis device;
- a spray pump configured to deliver softened water to spray nozzles;
- a flush pump configured to deliver RO-permeate water from said RO-permeate storage tank to surfaces of coils of said heat exchanger.
A method for inhibiting scaling and corrosion of metal surfaces in a heat exchanger, comprising:
- delivering softened water to spray nozzles of said heat exchanger during a cooling operation via a spray pump;
- delivering softened water to a reverse osmosis device;
- storing RO-permeate water from said reverse osmosis device during said cooling operation, and
- delivering said stored RO-permeate water to spray nozzles and/or coils of said heat exchanger during a flush operation.
