The invention is an air conditioning unitconsisting of a housinghaving at least one air inletfor receiving air to be conditioned and at least one outletfor discharging conditioned air, at least one fanfor moving air from the inletto the outlet, an air to air heat exchangerof the type that cools the air by diverting and cooling a portion of the air through an evaporative cooling means, heat exchange occurring across a plurality of barriersbetween the evaporatively cooled air and said incoming air, a vapor compression-type cooling system having an evaporator coilthrough which the outlet stream of air passes for further cooling of the outlet air, a condenser coilthrough which the evaporatively cooled air, stream that exits the air to air heat exchangerpasses, and a control systemthat at least determines the temperature of the roomair and controls the operation of the air-conditioner to operate only the air to air heat exchangerwhen the temperature is maintained below a pre-determined level, and operates both said air to air heat exchangerand the vapor compression-type cooling system when the temperature increases above a pre-determined level. The advantage of the invention is that it has a seasonal power efficiency of two to three times greater by comparison to an air-conditioning system operating only with a vapor compression-type system.

Air conditioner

A self-contained air conditioner unit comprises an enclosure including a first and second intake apertures positioned to communicate with outside ambient air and first, second, and third outlet apertures positioned to communicate with a habitable space in which the air conditioner is placed. A water reservoir is disposed at the bottom of the enclosure. A two-section heat exchanger is disposed in the cabinet over the water reservoir, each section comprising a plurality of vertically disposed, alternating wet air channels and dry air channels defined by substantially parallel opposing heat-transfer partitions. The first-section dry-air channels communicate with a pre-mixing chamber at intake ends thereof and an air-distributing chamber at outlet ends thereof. Each first-section wet channel communicates with the distributing chamber at intake ends thereof and the second outlet aperture at outlet ends thereof. The second heat exchange section comprises primary dry-air channels communicating with the distributing chamber at intake ends thereof and the first outlet aperture at outlet ends thereof and auxiliary dry-air channels communicating with the distributing chamber at intake ends thereof and intake ends of wet-air channel at the far ends thereof. Second-section wet-air channel communicate with the auxiliary dry-air channels at intake ends thereof and the third outlet aperture at outlet ends thereof. A wet partition comprising a capillary porous material is disposed in each of the wet-air channel, is oriented substantially parallel to the opposing heat transfer partitions and is positioned so as to substantially bisect the volume of the wet channel in which it is disposed. Each of the wet partitions extends into a volume of water contained in the water reservoir. Air moving means are provided for moving a volume of air from the first and second intake apertures through the dry-air channels and for moving air between the wet-air channel and the second and third outlet aperture.
