the invention relates to a latentw u00e4rmespeicher with a storage 1 to add a phasenwechselmaterials and a device 8 for the triggering of a crystallisation in the phasenwechselmaterial.the device 8 for triggering the crystallization has a first peltier element 14 and a second peltier element 15 to the formation of a gap 16 for recording the phasenwechselmaterials in distance from each other are arranged. the gap 16 between the peltier elements 14, 15 form a compartment in the phasenwechselmaterial flows.in the gap 16 between the peltier elements 14, 15 forming channels 19, in which the phasenwechselmaterial may reach at least a metallic body 17 arranged in thermal contact with the peltier elements.it has been shown that the crystallization of the channels 19 with the metal being in contact phasenwechselmaterials sure can be triggered. as the material of the metallk u00f6rper, especially stainless steel is particularly beneficial.
