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