Baseline findings

We did a freezer temperature log for six days. We found that there are about there types of events:

1. a ripple from -21 to -17 Celsius that repeats in a non totally regular manner about every hour. That is most likely the compressor kicking in when the temperature raises. So about 4 degree variation. See second Figure.

2. an irregular higher spike event about every six hours which seems to be the defrost cycle. About 6 degree variation. See full run figure.

3. independent events that seem to coincide with opening of the freezer door. That varies from about -8 degrees so 13 degree variation from the -21 that the freezer is set. See full run figure.

 

Six day run

 

One day run that shows better the smaller ripple caused by periodic compressor activity

These were baseline results without using an 'enzyme cooler'.
