Abstract
In evaporative cooling by injecting extremely fine water droplets into an airstream, the addition of cyclic injection provides superior control of the temperature drop of the air. The cyclic operation of the injection enables effective air cooling of outdoor and semi-outdoor areas, such as outdoor restaurants, even under conditions of high humidity. Small high pressure pumps that can be cycled on and off every few seconds for many millions of cycles make the air cooling method practical and effective.
Claims14
An apparatus for cooling air in an outdoor venue comprising a means for causing a flow of air in the outdoor venue,
- at least one nozzle positioned to direct a spray of water into the flow of air,
- a high pressure electric water pump in communication with a source of water and a water conduit connecting the pump to the nozzle,
- a selectable controller in electric communication with the water pump, the selectable controller adapted to timewise cycle the pump on and off periodically, and
- wherein the water conduit is approximately one-sixteenth inches in inside diameter.
An apparatus for cooling air in an outdoor venue comprising a means for causing a flow of air in the outdoor venue,
- at least one nozzle positioned to direct a spray of water into the flow of air,
- a high pressure electric water pump in communication with a source of water and a water conduit connecting the pump to the nozzle,
- a selectable controller in electric communication with the water pump, the selectable controller adapted to timewise cycle the pump on and off periodically, and
- including means to cycle the air flow on and off and means to coordinate the on and off cycle of the pump with the on and off cycle of the means to cycle the air flow.
A method of cooling air in outdoor venues comprising the steps of:
- causing a flow of air in an open space of the outdoor venue,
- spraying water into the flow of air by pumping the water at high pressure through at least one nozzle to disperse the water in very small droplets,
- selectably spraying the water cyclically as a function of time in response to perceived ambient temperature and humidity, and
- wherein the flow of air is periodically cycled on and off and the spraying of water is cycled on during the on cycle of the air.
A method of cooling air in outdoor venues comprising the steps of:
- causing a flow of air in an open space of the outdoor venue,
- spraying water into the flow of air by pumping the water at high pressure through at least one nozzle to disperse the water in very small droplets,
- selectably spraying the water cyclically as a function of time in response to perceived ambient temperature and humidity, and
- wherein the droplet size of the very small droplets average substantially 10–25 microns.
A method of cooling air in an outdoor venue comprising the cyclic injection of water droplets into a flow of air directed into the outdoor venue, said water droplets sized to evaporate within one second after injection and
- wherein the water droplet sizes average substantially 10–25 microns.
A method of cooling air in an outdoor venue comprising the cyclic injection of water droplets into a flow of air directed into the outdoor venue, said water droplets sized to evaporate within one second after injection, and
- wherein the cyclic on-time injection of water droplets is adjustable relative to the cyclic off-time non-injection of water droplets.
