Sublimation means the conversion of the solid phase directly into the vapour phase (without the involvement of phase liquid). Actually, for every substance this direct phase conversion occurs when the substance is below its triple point pressure and corresponding temperature.

Actually, one of the points where the dry ice sublimates is 1 atm pressure and the corresponding temperature isĀ -78.5C.
