‘Cause Baby It’s Cold Outside

Friday, April 6th, 2007

Everything that can be invented has been invented, right? I’m sure someone’s come up with this idea, but it occurred to me again this week when it was freezing outside after several beautiful days.

Unless you have air conditioning, the most power-hungry appliance in your home is probably your refrigerator. Mostly because the refrigerator needs to be running constantly. Otherwise it would kind of beat the point, right?

But in Chicago, it’s freezing outside for half of the year. What if there were a vent to the outside (like a dryer) that could be opened and closed with a thermostat and a little fan. If it was cold enough outside, that cold air would be used to cool your food. If not, the compressor would run as normal.

If it’s cold enough to use the outside air 4 months of the year (and in Chicago it’s probably more) and your fridge is using 75 watts an hour on average… That’s 216kWH/year… which comes out to about $18 a year. Hmm. That’s not that much. And then there’s the matter of the freezer… and that you might not want outside stink-air in your fridge.

Okay, then. Forget it. It probably makes a lot more sense to just get an efficient fridge.
