if the refrigeration door is kept open in a room what would happen in room temperature?..

Answer / hrithik raj

The fridge with the door left open will run pretty much
continuously to try to cool the inside. Our fridge doesn't
know the door is open, so it keeps running. The thermostat
inside never senses that the inside has cooled, so it tells
the compressor to stay on. The room will be cooled by the
fridge, but remember that the compressor dumps heat out into
the room all the while that it's running. And because the
fridge is not 100% efficient, there will be more heat
generated than there will be cooling. The result? The room
will eventually warm up.
I would disagree partially with the above answer. 1)
Efficiency is a term not really used for refrigerators. The
term coefficient of performance is used because it can be
and usually is greater than one (or greater than 100% in
other words) and equals the heat removed from the inside of
the fridge divided by the work input. 2) Now, if a perfect
fridge was running on a Carnot cycle (no friction in the
parts and other criteria) that gives the most cooling for
the least amount of work, the room would still heat up as
governed by the first law of thermodynamics. W=Heat from the
condenser - heat from the evaporator or W+QL=QH. In this
case all the terms are considered to be positive numbers.
Clearly QH>QL which means the room is getting warmer.
Probably the easiest was to understand this is that work is
going into the insulated room which means the overall energy
and therefore temperature is going up.

Answer / vijay jadhav

The room temperature will gradually increase as for the
first few minutes or may be hours the refrigerator will
work as such but after some time the temp of the room will
increase gradually because of compressor work.And which
will altimately increase the temp of the room.
