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.
Claims9
A water supply system for delivering adiabatic pre-cooling water to an air flow entering 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 directed at said air flow;
- a flush pump configured to deliver RO-permeate water from said RO-permeate storage tank to an outside surface of a coil of said heat exchanger, said water supply system further comprising a RO-reject storage tank configured to receive RO-reject water from said reverse osmosis device;
- wherein said spray pump is configured to receive cooling water from said RO-reject storage tank for delivery to said spray nozzles.
