Silly de-humidifier cellar question

[a twig]

Currently running a de-humidifier full time in the cellar as we are storing stuff in there at the moment...

There's a small window external window in the cellar, which I previously left open all the time, should I now have it closed?

A dehumidifier won't work very well in a cold room.
