With some seeds, yes.

Moisture is more important than temperature for MOST seeds.  Not all, but most.

HOWEVER....like any "cold storage"  the temperature generally slows down the degradation of the seeds.   It slows down the respiration (seeds breathe.)   So.....here is something interesting for you to read.

You will learn a lot about seeds in this article, but....

It is the oxygen level that causes the most degradation...at least in some seeds.    I think some of these studies have flaws, btw....but this article is very simplistic.  

Seed vitality

I will tell you that my grandmother and my mom stored seeds in tight jars, and/or in the refrigerator.  Both were better gardeners than I am, with all my fancy education.

I tend to trust what I learned from them.

And I refrigerate my seeds.  (I live in a climate where it gets down to zero in the winter.   So if I lived in the southern tip of Florida, I might NOT refrigerate my seeds, because things that grow naturally there might not survive 38 degrees F.  Does this make sense to you?)   I'm saying if you are growing tropical plants, no, don't refrigerate the seeds.  If you are growing things that survive temperate climates (in other words, they could go to seed, die back, and come up from that seed after the freeze/thaw of winter) then refrigeration is good.

LIke most things, it's a "must think through it."
