Title (EN) HEAT STORAGE DEVICE
(FR) DISPOSITIF D"EMMAGASINAGE DE CHALEUR
Abstract: front page image
(EN)In a heat storage device comprising a container (40) which contains a salt hydrate, the heat of fusion of which is utilized to provide high heat capacity in relation to the volume, oil is circulated by a pump (50) through a number of channels (62, 65) leading to outlet openings (55) distributed in the salt hydrate. A slide valve (58, 69), the sliding valve body (58) of which is influenced by the pressure on the delivery side of the pump, automatically controls the distribution of oil to the channels in such a manner that solidification of the salt hydrate during heat discharge from the storage takes place in a regular progressive way so that the oil can always find non-blocked outlet openings to flow through.
(FR)Dans un dispositif d"emmagasinage de chaleur comprenant un recipient (40) qui contient un hydrate salin, dont la chaleur latente de fusion duquel est utilisee pour fournir une forte capacite calorifique par rapport au volume, de l"huile est mise en circulation par une pompe (50) au travers d"un certain nombre de canaux (62, 65) conduisant a des ouvertures de sortie (55) distribuees dans l"hydrate salin. Une vanne a tiroir (58, 69) dont le corps (58) est influence par la pression du cote du debit de la pompe, controle automatiquement la distribution de l"huile dans les canaux de telle maniere que la solidification de l"hydrate salin pendant la decharge de chaleur depuis l"emmagasinage s"effectue de facon progressive afin que l"huile trouve toujours des ouvertures de sortie non-bloquees afin de s"y ecouler.
