(a)Chill only (coldroom) operating on R134a
Ambient temp @ 2degC
(b)Freezer (coldroom) operating on R404a"
Ambient temp @-22degC
At these conditions the system would not need to run .... thus giving you the ideal operating conditions.

This sounds like an exam question :eek: and there probably isnt a difinative answer.
Systems are designed to cope with a wide range on ambients and if you live somewhere that falls out of this range then you get a high ambient system or one with head pressure control.
Can you be a little more specific in what you are looking for
