Abstract: Disclosed is an air conditioner having an excellent air cleaning function, the air conditioner including a cabinet having a first air inlet and discharging conditioned air; and a filter unit provided at the cabinet and cleaning air drawn therein, and selectively performing an interlocking operation for supplying purified air to the cabinet or an independent operation for discharging the purified air directly to the outside thereof.

Abstract: A portable air chiller for providing air conditioning in a variety of environmental circumstances. The portable air chiller includes an insulated container capable of effectively containing a endothermic substrate, an in-flow vent and out-flow vent positioned to communicate air flow from the exterior of the container to the interior of the container. A fan located in the out flow vent facilitates conditioned air movement out of the interior of the portable air chiller. The interior of the portable air chiller houses a endothermic substrate holder which practically traverses the length and width of the interior.
