Can a fridge, left open in a closed room, be used to cool the room?
Can a fridge, left open in a closed room,
be used to cool the room?
* No. Instead it will heat the room.
** If the fridge is kept open in a closed room,
the chillness coming out through the front door of the fridge
is cancelled by the heated air coming from behind.
***Under normal circumstances, the heat from inside the fridge is taken out by the compressor and let out in the air behind the fridge.
**** Apart from this,
in any electrical appliance, a part of the electricity supplied is wasted as heat,
this heat will raise the temperature of air inside the room.
