An air conditioner operating on a compressor-condenser-evaporator circuit utilizes water cooled by air flowing over an evaporative medium through which the water flows to cool a condenser coil located in a continuous serpentine channel in a sump member located at the lower side of the air conditioner unit. The condenser coils include offset intertwined upright coils that provide a large heat exchange surface with water flowing in the channel to a pump intake region of the sump. A pump is provided to supply the evaporative medium with water from the pump intake region of the sump for continuous circulation through the evaporative medium and the sump channel. A water distributor system supplies water uniformly to the top area of the evaporative medium by creating a film of water that is evenly distributed across the top of the evaporative medium. A raised area of the sump provides access to the interior of the evaporative medium without the need for a water sealing arrangement and a central platform supports the refrigerant compressor, pump and other accessories above the sump channel. The offset relationship of the condenser coils promotes turbulent flow of water that enhances heat exchange between the intertwined coils and the water.
