A final wrap-up on the Freezerator...

I did a calculation on the energy used over the last 24 hours and 58 minutes, and the daily power use, calculated for a 24 hour day, was 278.74 w-h/day. which sounds astoundingly good, but the weather has been on the chilly side, and since I don't heat my kitchen unless it is a byproduct of cooking, it has been cool in there, and as can be seen in the chart above, the regular temperature in the kitchen is in the low 60's.

I intentionally made sure that the Mulitlogger board, with it's own 1-wire temperature sensor was close to the top of the refrigerator so that the heat given off by the condenser would be clearly shown.

Again, it is clear that the work of the compressor is an inverse image of the temperature inside the Freezerator. Pretty good indication that if you have one of these refrigerators with internal condenser coils, you don't want to inhibit airflow to that surface. In the case of my Freezerator, the back, the sides and even the top is a heat-dump surface.

The discontinuity at the 50 minute mark was me getting food for lunch.

All is working well.
