Deep Freezer (-17deg.C) with auto defrost
 

Is there such a thing?

It gets down to -30 here during the Winter, and automatically defrosts
around May - does that help? ;)

Yes, every frost free one.

However, they are significantly less reliable than non-frost-free ones,
as the frost free/defrost mechanism is the least reliable part.

How long does the de-frost cycle take?
Presumably the food contents in the freezer are exposed to above freezing
temperatures for a while?

Don't know.

No. The evaporator (where the frost collects) is separate from
the food, and it's only that which is defrosted. There's no cooling
whilst that happens, and it relies on the heat capacity of the food
to stay cold.

A quick glace at the temperature logs for my freezer (not frost free)
seems to indicate it runs for about 10 minutes, and then takes 50
minutes before it warms up enough to run again. A frost free one
defrosts during that idle time (although I don't know if it does it
every idle time - I suspect not).
