Abstract

Heat exchange method and apparatus are disclosed which include the use of o non-mixable media of different temperatures that are brought in direct contact with each other to effect the transfer of heat from the heating medium to the heat storage medium. One of the media is normally a fluid and the other is preferably a substance -- such as a crystalline material -- which is operable between solid and liquid phases, whereby the latent heat produced by the phase transition is utilized in the heat exchanging process. Owing to the non-mixability of the two media, the first medium is bubbled through the second in direct heat exchanging contact when the second medium is in the liquid phase. A supply conduit including a submerged perforated portion is used to introduce the first medium within the second, an imperforate by-pass conduit being also provided for conveying the first medium in heat transfer relation through the second medium when the supply conduit is clogged by the second medium when it is in its solid phase.
