If you are looking for a portable air conditioner that has no outlet such as hose that feeds out a window than you may be thinking of a evaporative cooler. A standard air conditioner unit that has a compressor and uses refrigerant under pressure needs a outlet to pump out hot air. In the case of a portable A/C unit this is usually done with a hose that is attached to the unit and than fed out a window or other outlet. Evaporative coolers dont need a hose attachment to pump out hot air. Evaporative coolers are not air conditioners in the sense that they dont use a compressor and refrigerant to cool a space. A evaporative cooler uses water that is pumped up to the top of pads that water is than filtered down. A fan is than used to blow air through the pads cooling the air.

Dry climates such as the American South West are where evaporative coolers are used widely and are often the only cooling system needed.

The main components are a water pump, cooling pads, and a fan to blow air through the pads.
