The surface area increases from 2xy + 2xh + 2yh to 2xy + 3xh + 3yh While the volume increases from xyh to 1.5xyh. Not that far off from linear in this range. By the way, what is the temperature gradient in your fridge from bottom to top ? I'm wondering if extra external insulation on the top of the fridge would have much of an effect. |

My Freezerator, as most of the currently produced units, have the integral coils, and the outside surfaces become the heat radiating surface... the top, the two sides, and the back, all have integral coils. So to insulate would have a negative impact on efficiency. Personally, I think that the integral coils feature costs the planet a huge amount of CO2. Only reason for it that I can imagine is that the coils are much less likely to be damaged during shipping. After shipping, it's down hill. -AC
