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.

Abstract: A air pre-cooler, water reservoir and distribution apparatus for evaporative air conditioners, incorporating an insulated, increased volume, self-cleaning water reservoir and a unique water distribution system, in which the cooling efficiency is increased through enhanced air water contact, and provides cleaner and cooler outlet air through particulate removal.

Abstract: An air cooling apparatus comprised of an injector cabinet fitted with a plurality electric solenoid operated injector valves, or standard nozzles 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 the thermostat setting. This water injection module may be located either upstream or downstream of any air-moving device. The device is also adaptable for use with existing coolers as a retrofit kit.

Abstract: An air cooling apparatus comprised of a cabinet, in which the upper portion contains an air inlet area and a water distribution header fitted with a plurality of water spray nozzles, and is also fitted with an insulated centrally slopping bottom pan which provides the cooling water reservoir and contains a debris collecting sump with a purge/drain valve, and a platform for mounting a submersible water circulation pump. Within the cabinet is mounted a vertical decreasing flow path air duct, which is fitted at its top with a basket containing a solid nonabsorbent aggregate cooling media over which is sprayed the re-circulated cooling water, and its bottom opened to an internal air chamber from which the cooled air is extracted. The bottom air duct opening is arranged to provide inertial separation of entrained liquid and solid particulate matter from the air stream.
