a. When using an air sensor, the wine
bottle temperature is mainly
controlled by the average air
temperature. If the set-point is 55F
with the differential 4F, the cooling
unit turns on at 59F of air
temperature and turns off at 55F of
air temperature. The average air
temperature is 57F, and then the wine
temperature is around 57+/-0.5F. The
air is light enough to change so
quickly that it maintains relatively
constant average temperature that
would prevent wine bottle
temperature from varying.
