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.
Claims4
A water supply system for delivering adiabatic pre-cooling water to an air flow entering a heat exchanger, comprising:
- a coil flush water flow path including a water softener, a reverse osmosis device, and a reverse osmosis permeate storage tank, said coil flush water flow path having a terminus located to deliver softened reverse osmosis permeate to an outside surface of a coil of said heat exchange device;
- and
- a first adiabatic cooling water flow path including said water softener, an adiabatic cooling water spray pump, and adiabatic cooling water spray nozzles directed at said air flow entering said heat exchange device.
