Abstract: An intermixing assembly for an evaporative air conditioner includes an elongated housing and a nozzle positioned in the housing. The housing has an inlet for receiving ambient air from a source thereof and an outlet. The nozzle is positioned adjacent the housing outlet and has a first inlet for connecting to a source of pressurized water; a second inlet for connecting to a source of pressurized air; and an outlet for dispensing the pressurized water and pressurized air and mixing them with the ambient air to form a mist near the housing outlet.

Abstract: An evaporative air conditioner system includes a heat exchanger having an inlet and an outlet and a plurality of passageways between the inlet and the outlet; a pump and nozzle assembly for introducing pressurized air and water to the inlet of the heat exchanger to create a mist of water droplets suspended in air; a vacuum assembly for creating a partial vacuum near the outlet of the heat exchanger to draw the mist through the passageways and to the outlet of the heat exchanger to remove heat from the heat exchanger through evaporative cooling; and a transfer mechanism for moving a medium past the heat exchanger to remove heat from the air without permitting the medium to mix with the mist drawn through the heat exchanger.

Abstract: A heat exchanger assembly includes a hollow housing having a first horizontally-extending section and a second vertically-extending section. A perforated support tube is positioned in the first section and has an inlet for receiving water and air from an intermixing assembly and a series of holes for expelling the water and air. A heat transfer coil is wound around the perforated support tube for carrying a cooling medium. A vacuum source is coupled with the second housing section for drawing the water and air from the inlet in the perforated support tube, through and out the support tube, over the heat transfer coil, and toward the outlet in the second housing section to cool the heat transfer coil through evaporative cooling.

Abstract: A self-contained evaporative air conditioner system includes a housing having a central chamber, a lower chamber, and an upper chamber; a heat exchanger positioned in the central chamber; an air nozzle and a water nozzle for creating a mist of water droplets suspended in air in the lower chamber; an ambient air vent for introducing non-pressurized ambient air to the lower chamber; a vacuum assembly for creating a partial vacuum in the upper chamber to draw the mist and ambient air through the heat exchanger to remove heat from the heat exchanger through evaporative cooling; a return air vent for receiving air to be conditioned; and a fan for drawing air from the return air vent through the heat exchanger to remove heat from the air without permitting the air to mix with the mist and ambient air drawn through the heat exchanger.
