At home, people normally use "nevera", but maybe in printed matters you'll read "frigorífico", but both are ok in Spain.

NEVERA is a fridge, freezer, refrigerator but can also be a cooler you bring to the beach, a place in the mountains where snow can be found around the whole year or a place where snow is preserved. FRIGORÍFICO is a household item or cooled room use to preserve sth, it is also an adjective referring to a refrigerated truck and a device or mixture that lowers the temperature. Depending on the area you´ll find more common the use or one or the other.

Nevera es el nombre que normalmente la gente llama al frigorífico...No escucharás a nadie referirse al frigorífico al menos en España, aunque sí es usado en Latinoamérica.

I think there's no difference. However, it seems like nevera is more used in South America, whereas frigorífico is more common in Spain.
