Can you open the refrigerator to cool a room? When it's hot outside, it could be tempting to open the refrigerator door to cool off, but will it actually work? The response is based on a number of refrigerator-related variables.
Although you may fan yourself to stay cool with the door, you cannot truly reduce the room's temperature. This is due to the fact that refrigeration is a rather inefficient process. The room gains more heat through the exhaust vent than is removed from the refrigerator's inside. However, you can only use the refrigerator to cool a room if it is turned off and you are using the box's already-chilled contents, which act as a huge ice cube. If the refrigerator's heat vents are in a different room, you might also utilize it to chill the space.
