If the door of a refrigerator is kept opened on the hot day of summer,
what about degree C do you think room temperature falls? What degree
Centigrade do you think the temperature of the room will be, when it
is assumed that it is first 36-degree C? Please tell me your opinion.

Hint: when the door is shut, where do you think the heat that is removed from
the inside of the fridge goes?

It goes to the cooler of a refrigerator, doesn't it? That is, do you
say the temperature of the room does not change?

The temperature in the room will go UP.

A refrigerator is a box containing heat-transfer engine that moves heat from
inside the box to outside the box. That's all. It just moves heat from one
place to another. And it does so with less than perfect efficiency; that is,
some of the energy it uses is wasted, and dissipated as excess heat.

No, it will change. It will actually get warmer. The heat produced by
simply running will add to the temperature. This is the same thing as
intalling an AC unit inside a room.

Because the heat extracted by the refrigerator is exhausted into the
room, the temperature will not fall (and since no refrigerator is
anywhere close to 100% efficient, the temperature will rise).

However, because the room air does not mix perfectly, the temperature
will fall in front of the open refrigerator.

This is a bad substitute for air conditioning, because it will cause
the refrigerator compressor to run full-time; it is not designed to do
this and will fail rapidly.

Right. Except the room would actually get hotter!

The first principal of refrigeration is that there is no such thing as
"cold". Cold is merely the absence of heat.

A refrigeration device (fridge, freezer, a/c, etc.) does not *make*
cold, it simply moves the heat from one place to another. In the case
of a refrigerator it moves the heat from inside the cabinet to the
outside of the cabinet where the room air takes it away (plus also
generates some heat in the process).

In your postulation - if you're taking heat out of the room air (by
leaving the fridge door open) and putting it back into the room air
(plus adding more heat from doing that work), how much colder is the
room air going to be?

The room temperature wouldn't change.. however, if your wife catches you
experimenting by leaving the refrigerator door open, you're body will soon
be at room temperature..

yeah.. it's a boring day at work today. haha
