you place an air conditioner in the center of the room assume the room is sealed and that a fan mixes the air in the room well. you let the air conditioner run all day long and in the late afternoon you come back what happened to the temperature of the room and why ( assume that it happened in a hot summer morning)

The room will be hotter than it was before, because you are also exhausting the heat generated by the air conditioner into the sealed room. Because the unit will generate more heat then the amount of cool air that it produces, the room will be hotter.

This is a simple one to answer.
The room will become very hot.
Why?
Go to outdoor portion of your air conditioner and feel the heat being discharged from the exhaust. It is very hot.
If the A/C is entirely inside a sealed room, that hot air is trapped in the room with the operating A/C.
Since the energy used to operate the motor in the A/C turns into heat and must be eliminated, the manufacturer of the unit discharges that heat along with the exhausted hot air. (An A/C operates by moving heat from inside your home to the outside where it won't be a problem for the home occupant.)
Once you add the waste heat energy to the equation, the added heat exceeds the cooling capacity of the A/C. The net result becomes an increase in room temperature.

The average exhaust temperature would be hotter than the cold air the AC unit created. It would be hotter in the room due to thermal inefficiency. ...this is a shoot from the hip answer :(
