When you open the door to a refrigerator for a minute what happens to the energy?

If you leave the door open, heat is merely recycled from the room into the refrigerator, then back into the room. A net room temperature increase would result from the heat of the motor that would be constantly running to move energy around in a circle.

Why should we avoid keeping the refrigerator door open for a long time?

Modern refrigerators are designed so that abnormal usage like this is not likely to harm the refrigerator itself. The cooling coil(s) is likely to become frosted or ice-clogged if the door is left open too long, which means that it may not get cold inside even when the door is closed again (air circulation is blocked).

When you open your refrigerator, the cold air that keeps your food fresh escapes and is replaced by warm air from the room. Your refrigerator’s compressor has to then drive the warm air out and bring the temperature back to normal, elevating not only your monthly energy bill, but also your environmental footprint.
