How to More Cheaply Cool a Fridge


I've always wonder why we artificially keep our refrigerators cold in the winter. It does not make sense to spend money and energy to heat our homes, and then spend more money and energy to cool a small part of our houses.


My idea is very simple. Have a completely automated system that can determine if the outside air is cold enough for the fridge or freezer by simply using an outdoor thermometer. If the air is cold enough, then a small electric fan and pipe can blow the cold outside air in the refrigerator. Of course, this pipe will need to have at least one filter to prevent outside bugs and insects from entering the refrigerator. Or, the outside air can be used to directly cool the compressor so that the outside air does not directly enter the fridge, thus the outside air can not possibly contaminate any food.

As a result, I believe this simple solution will use significantly less energy than the current alternative of always using a compressor to regulate the temperature in a refrigerator. The only problem that I can think of is that the outside air temperature fluctuates greatly, thus it is much more complicated to keep a constant temperature inside a refrigerator. Fortunately, I think this is a simple problem for engineers to solve, since the easiest solution is to check and adjust the inside temperature of the fridge more often.

In conclusion, I think my simple idea can help everyone use less energy (thus help the environment) and save money.
