Abstract:

An air cooling apparatus comprised of an injector cabinet fitted with a plurality electric solenoid operated injector valves which are controlled by an advanced computerized system which regulates the amount of moisture added to the air stream by activating the injectors based on direct measurement of indoor and outdoor dry bulb and wet bulb temperatures, mass flow through the apparatus and thermostat setting. This water injection module is location downstream of any air moving device.

Description

SUMMARY OF THE DRAWING

The object and attendants advantages of this invention will become readily apparent to anyone familiar with the field of the invention following the detailed description taken in conjunction with the accompanying drawing in which:

FIG. 1 is a cross-sectional view of overall system.

PREFERRED EMBODIMENT OF THE INVENTION

In the exemplary embodiment of the invention a substantially cubic or cylindrical injector nozzle cabinet 10 is fitted with a water manifold 12, which is provided with a plurality of electric solenoid injector valves 11, which receive water from a filtration system 13 which is fed from a domestic water source 14.

The ambient air wet bulb temperature is measured by a sensor 1, and the ambient dry bulb temperature is measured by a sensor 2. These signals are fed to a microprocessor 7, which calculates the ambient relative humidity and the grains of moisture per pound of ambient air. The inside wet bulb temperature is measured by a sensor 3, and the indoor dry bulb temperature is measured by a sensor 4; These signals are fed to a microprocessor 7, which calculates the indoor relative humidity and the grains of moisture per pound of air. The amount of inlet air is measured by the mass flow sensor 6, which sends a signal to the microprocessor 7, which in turn calculates the amount of moisture to add to the ambient air stream and the number of strokes per second for the water injectors 8.

Claims

I claim:

1. An apparatus for cooling air by means of the latent heat of evaporation of water comprising of a cabinet containing a new and novel plurality of electric solenoid operated injector nozzles whose injection rate is controlled by a microprocessor that senses mass flow, inside and ambient wet and dry bulb temperatures and the set temperature of the thermostat, determines the relative humidity of the ambient and inside air and properly adjusts the amount of water injected into the inlet air stream as well as controlling temperature in houses and industrial areas.
