No. We should not do that. If we left the fridge door open, it will cool the room a little but also heat it up a lot more.

NO. This is basic difference between a refrigerator and an air conditioner. The food kept in fridge gets cooled because refrigerating fluids in the system takes away its thermal energy ( temperature ) and dumps that energy into atmosphere ( i.e., The kitchen ) . So if you open the fridge door one...

So if you open the fridge door one part of the fridge cools the room and the other heats up ( more than cooling effect ) . Where as in AC we have that heat dumping out of the room , that makes room cooled . So if if you open the fridge door your current bill increases ,making you to lose your cool ;-) read less

This is a tricky question, and the answer may surprise you: NO! A fridge can be thought of as a "heat pump". It takes air inside the fridge and cools it by removing heat from it. This heat has to go somewhere, though, and is usually blown out the back of the fridge by a little fan. (If you feel the...

This is a tricky question, and the answer may surprise you: NO! A fridge can be thought of as a "heat pump". It takes air inside the fridge and cools it by removing heat from it. This heat has to go somewhere, though, and is usually blown out the back of the fridge by a little fan. (If you feel the back of a fridge on the outside it will usually be warm if the unit is running). For this reason, when a fridge is running it is really warming up the room a little bit. In fact, since we can’t design a fridge to be perfectly efficient (the 2nd law of thermodynamics guarantees this), some of the electrical energy gets converted to heat, so more heat gets dumped outside the fridge than gets pumped out, so even if you open the fridge door to let the cool air escape the fridge will still be heating the room more than cooling it. read less
