Patent ID: 7322205

Claim:
A packaged cooling device for conditioning air within a conditioned space, comprising: a housing enclosing the following elements: a refrigerant loop including a compressor, a condenser, and a direct-expansion evaporator; a first air mover that moves air through a conditioned space; an evaporative condenser cooling section having an air inlet to receive outside air and a plurality of barriers that define dry passages and wet passages; an indirect evaporative cooling section having a first air inlet to receive outside air, a second air inlet to receive building return air, and a plurality of barriers that define dry passages and wet passages; at least one water distribution system that provides water to the wet passages of the indirect evaporative cooling section and to the wet passages of the evaporative condenser cooling section; and a second air mover that moves air from the air inlet of the evaporative condensor cooling section through the evaporative condensor cooling section to the outdoors, and moves air from the second inlet of the indirect evaporative cooling section through the wet passages of the indirect evaporative cooling section to the outdoors, wherein the elements are arranged such that: the outside air entering the first air inlet of the indirect evaporative cooling section is indirectly evaporatively-cooled in the dry passages by conductive contact with the wet passages through the barriers to cool the outside air, and the outside air entering the air inlet of the evaporative condenser cooling section cools water passing through the wet passages of the evaporative condenser cooling section for circulation through the condenser.
