I think that is the term. Been used for cooling electronic equipment.

There're a couple of guys on a yahoo refrigerator alternative list who've got experience with parafins. But you're likely thinking salts for lower temps, as were proposed a decade or few ago.
Pretty sure you're going to find it's immensely cheaper and easier to simply increase your mass substantially, unless you're trying to retrofit. We don't phase change, but large mass is our (totally passive) heating/cooling system. Works great.
