Default Fridges: weird "fast freeze" switch

The instruction guide for our Bosch fridge tells us to press
a certain switch under two circumstances:

1: if the room temperature is below 18 degrees C
2: if we want to fast freeze stuff

What actually does this switch do? Why should the fridge need
a switch for different room temperatures? And why would the
switch for having a cold room (in which your fridge should
need to work less hard) be the same one for freezing stuff
quickly (for which it should work harder)?


I expect this is a single compressor fridge freezer. It is
widely know (especially in this NG) that this type of machine
has a design compromise whereby if the room temperature is
too low, the compressor does not switch on and the freezer
defrosts.


You can get freezers with two compressors? I didn't know. I am
considering buying a large chest freezer which will be sited
in an unheated outside garage. What should I look for?
