It's easy to do with the kitchen off the back of my house. With 2' stone walls (C ~ 50 Btu/F-ft^2) inside R10 insulation and RC = 500 hours, the kitchen temp changes slowly. Starting at 36 F, it would cool to 30+(36-30)e^-(24h/500h) = 35.7 over an average 30 F January day. Leaving the kitchen door to the rest of the house open for a few minutes a day makes up for that cooling. >At that temperature, you don't even need a refrigerator, just a freezer. Right, but then spring happens. Maybe the freezer needs a thermostat that turns on a 15 watt bulb in the fridge box when the freezer temp rises to 10 F. Where can I find one of those? Nick
