Question
If you open the door of your refrigerator with the hope of cooling your room, you will find that the room’s temperature actually increases somewhat. Why doesn’t the refrigerator remove heat from the room?answer from internet: The refrigerator doesn't eliminate thermal energy; it merely pumps it from one place to the other and consumes ordered energy in the process. If you open the refrigerator, it will just move heat around the room and produce additional thermal energy in the process. The room will actually become warmer.
PLEASE GIVE ME SOME ADDITIONAL INFO ON THIS ANSWER, OR CLARIFY. I'M ASSUMING THAT THE REFRIGERATOR MOTOR PLAYS A ROLE.
Explanation / Answer
You would be right, then. The refridgerator essentially has to work more to keep the inside of the refridgerator cool; the motor has to kick in and work harder to do this (have you ever felt the floor behind a refridgerator? It's usually very hot back there). More to the point, think about the thermal efficiency of the refridgerator. Since there is no (ideally) efficient heat engine/cycle, you cannot get a 100% return on your input.
More to the point, the refridgerator has to take heat from an input vent. It is extremely true that the refridgerator CANNOT take in more heat than what is coming into the room from the outside if it is really that hot.
