ABSTRACT:
A device for recovering heat during the drying of a load in a clothes dryer of the once-through external air type, said machine comprising a tub for containing a load to be dried, a conduit for feeding external fresh air into said tub, and a conduit for expelling hot moist air from this latter and for feeding it into the environment in which the machine is located. A container is provided containing a phase change material or PCM in which heat transfer surfaces or channels are present, along or within one of these latter there passing at least part of the hot moist air from the exit of the tub so as to transfer thermal energy to said PCM, which changes its physical state or phase, within another of said channels or along another of said surfaces there passing at least part of the fresh air entering the machine and to which said energy is transferred by the return of said PCM to its original physical state or phase.
