Sublimation is process in which solid is changed directly to vapour state or vice-versa mostly at room temperature. For example, naphthalene balls change directly into vapour state without any heating whereas ammonium chloride is required to be heated to see this process. So it's not necessary that sublimation takes place only at room temperature, it depends upon the matter you are dealing with.
