The basic design of a window air conditioner consists of an enclosed unit containing a compressor, a condenser, and an evaporator. The unit is typically mounted in a window or a wall opening, with the front of the unit facing inside the room and the back of the unit facing outside.

To operate a window air conditioner, you typically need to plug it into an electrical outlet and turn it on. The unit will then draw in warm air from the room, cool it using the refrigeration cycle, and release the cool air back into the room.

Window air conditioners come in a range of sizes and cooling capacities to suit different room sizes and cooling needs. They are generally affordable and easy to install, but they can be noisy and may not be as energy-efficient as other types of air conditioning units, such as central air conditioning systems or ductless mini-split systems.
