all fridge temperatures are allowed up to - 49 degrees Fahrenheit
36°
around 30
to seal it from ambiant temp out side the fridge
it depends on what temp. you set it at. mine (49-53)
Refrigerators should be set at 40°F maximum.
It depends COMPLETELY on the temperature (and humidity to a lesser extent) outside the refrigerator. If the ambient temp is below - say 40 degrees - the inside temp of the refrigerator, then it need not be on at all. If its hot enough than it won't be able to stay cool inside even if it runs continually.
Generally 2 to 8 °C (36 to 46 °F) is ideal for the refrigerator compartment and -18 °C (0 °F) for the freezer.
Two to three days at room temp is fine
depends on the model of it. a refrigerator needs to keep food at 42 degrees or lower to keep the food same, if your drink chiller can maintain that temp then yes, if not, no
The average refrigerator ranges in temperature from 35 - 40 degrees Fahrenheit. There are wild differences due to surroundings,room temp., efficiency, humidity, and where your refrigerator is located, whether its in a cut out or surrounded by walls, or not. Other factors such as how often the refrigerator or the freezer is opened and closed and all the above factors also relate to the freezer since in most modern models difuse cold air from the freezer to the refrigerator. So in the short of it most models average temp is between 35 - 40 degrees Fahrenheit.
it turns on to regulate the temp inside and off once it's reached
In basic theory yes it would get colder by installing a lower temp thermostat. However the common household refrigerator was not designed for that application,..most household Units set at the lowest temp can cool down to about 35*F in the refrigerator section,and 20-28*F in the freezer section... putting in a lower temp thermostat may cause the unit to run constantly as it tries to achieve the lower temp settings and If your unit runs constantly your electric bill will skyrocket and I would estimate that within 3-7 days of constant running you would either burn out a thermal overload or the compressor unit...
