Let's look at some general issues. Does this solution target a problem
that you will have?

Allowing moist air to enter the freezer will allow frost to build up,
increasing the need to defrost.

Will you be opening the lid of the freezer frequently?

Once open, will you have the freezer lid open for long periods of
time?

How humid is the room in which the freezer will be kept? Cellars tend
to be humid. Warm summer air can hold more moisture than cold winter
air. Opening the lid in a humid cellar in the summertime will increase
the need to defrost.

Modern fridge and freezer seals are quite air-tight. Do you have cold
air leaking from your current fridge? Probably not.
