Can opening the refrigerator door cool down the room?

Refrigerators, like air conditioners, can both provide cooling. So when the weather is hot, can you open the refrigerator door to cool down the room?

The answer is: No!

Like air conditioners, refrigerators rely on the refrigerant to absorb heat when it vaporizes and release heat when it liquefies to achieve "refrigeration". During refrigeration, the refrigerant first passes through the compressor and condenser, and then enters the evaporator to evaporate. Evaporation requires heat absorption, so the heat in the refrigerator is absorbed and the temperature drops.

Subsequently, the refrigerant, after absorbing heat through evaporation, returns to the compressor and condenser to liquefy and release heat.

It can be said that refrigerator "cooling" is the process of transferring heat from the inside of the refrigerator to the outside.

Because the refrigerator's heat dissipation components are in the body, unlike air conditioners that have outdoor units, the heat generated by the refrigerator can only be discharged into the room, and the heat in the room is not reduced.
Therefore, opening the refrigerator door will not cool down the room.
