ABSTRACT:
An air conditioner utilizing an evaporatively cooled main heat exchanger for receiving ambient air and indirectly reducing the total heat content of the ambient air for delivery to a point of use. The air conditioner includes an air diversion mechanism which diverts a portion of the air after its passage through the main heat exchanger and supplies the cooled diverted air for use in the evaporative cooling of the main heat exchanger. A feedback mechanism may also be provided for diverting another portion of the air after its passage through the main heat exchanger and supplying this cooled diverted air for mixing with the ambient air prior to its being received by the main heat exchanger. An exhaust air return mechanism may also be employed to direct the air which is used in the evaporative cooling of the main heat exchanger to a preliminary heat exchanger which utilizes that relatively cool air for indirectly reducing the total heat content of the incoming ambient air prior to its being supplied to the main heat exchanger. The air diversion mechanism, the feedback mechanism, and the exhaust air utilization mechanism all cause regenerative actions to occur which reduces the temperature of the air delivered to a point of use to temperatures below those which could otherwise be achieved in such air conditioners.
