An air conditioning unit will not function in the middle of the room, to cool it. An air-conditioner is a ‘heat pump’; it pumps heat and to cool a room must exhaust the heat from the room outside to a ‘heat sink’. Without such an exhaust, the heat stays in the room, the energy used by the air conditioner unit itself is added and the room gets even warmer. The air conditioner cannot destroy heat; it can only push it around and even can work to pump it into a higher temperature area. The same mechanism works in refrigerators, freezers, dehumidifiers, ground-source heaters and other such devices.
