Does a refrigerator become instead of an air-conditioner?
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. |

That is, do you say the temperature of the room does not change? 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.. lucy :) yeah.. it's a boring day at work today. haha "Dan O." wrote in message ...
