temperature in freezer

[AleksanderNH]

Hello guys!
going to have my final exam in a few days.
Considering that I have gone to school for almost a year now, this is probably a lame question.

I have mounted a freezer/ freezing room (not sure what it's called in english)
So I just had to be sure if the right temperature is -18 degrees celcius or if it is -22 degrees celsius?

Thanks in advance!

The temperature can be whatever you desire.

Normal domestic frozen food should be stored at no warmer than -18°C, commercial stores may go for -22°C or beyond.

It does depend on the product that you are storing.

Sometimes local regulations gives you the temperature.
In Belgium, frozen goods must be kept at a temperature >-18°C, so with -22°C, you have some safety margin.
If temperature goes higher then -18°C, then an alarm has to be triggered after a certain waiting time for every freezer larger than 10m³ (for Belgium) Temperature must also be recorded at least every 15 minutes with an automatic recording (again for freezers >10m³)
