These old girls were built at a time when the market was not yet saturated by refrigerators, so companies were building units to sell to first time buyers. Later, in the 50s and beyond, during the hyped up drive to sell to consumers (and not just citizens), manufacturers increased the dimensions of the refrigerators (and especially the freezers for all those TV dinners) to accommodate new tastes and more storage. Another way to increase size, was to reduce the insulation thickness, thus the inside dimensions got larger without increasing the footprint. I suppose the larger freezer capacity and the energy intensive defrosting that goes with it doesn't help matters either. Then there's the strip heaters they added to the door mating surfaces to prevent condensation, plus the heaters used in the cabinet walls for the same type of issues, associated with poor insulation. I think there were a lot of reasons why refrigerator / freezers went through such a long period of inefficiency (arguably continuing to this day). Production of junk is the industry standard when that industry is based on profit and growth. Regardless, I think people should have an affordable alternative. I would like to produce one. You did a great job with this freezerator, AC_Hacker! I think it demonstrates how simply modifications can make a huge difference. I'm curious, have you ever attempted to measure the evaporator temperature to get an idea what the delta T is?
