In a sealed room with good insulation effect, what will happen to the temperature in the room after opening an air-cooled refrigerator door for a period of time? Why?

There is almost no change, and it may get hot after a long time, because the condenser is also radiating while the refrigerator is cooling, so you can feel the heat beside the running refrigerator (box-type radiating type).

Other parts, such as light bulbs, will also heat up after a long period of operation (the refrigerator door is opened and electrified for a period of time), so the room will heat up.
