The frequent and brief fluctuations of the air temperature around the set point enable the operating
principle of the device (specified below) to reach a stable average temperature in the bottle, which in
contrast to the air has a mass and inertia.
Very frequent ON/OFF cycles:
Generally, frequent operations (linked to the internal ventilation) can be detected in these devices.
The mixture of air homogenises the internal temperature and, in the event of the door being opened
for prolonged periods, ensures the quick return to the original temperature. However, you can check
that:
1. The ambient temperature is not too high.
2. A large number of bottles was recently added.
3. The door is not opened too frequently.
4. The door does not close correctly.
5. Joint on the door is not airtight.
6. Sufficient air circulation is provided around the device.
2.8 Noises
This concept is very objective.
Depending on its location, the time of day and a person's perception, the concept of noise varies
greatly. As means of an example, during the day a mosquito is completely inaudible. However, once
it is night and the noise of everyday life subsides, nothing is more unbearable, however, if the dB(A)
levels are measured it cannot be perceived.
Gurgling noise, small creaks and light bangs caused by the circulation of gas are normal.
The contraction and expansion of the internal walls can generate creaking noises.
In certain devices, the number of ventilators ranges between two to five, which depending on the
model generates varying degrees of blast noise (recoding around 41 decibels). This is perfectly
normal.
