fig1 b an alternative embodiment is illustrated that in addition to the components already described in connection with fig1 a has additionally a conduit 24 and a controllable flap 23 which is arranged in this conduit 24 through this line 24 if available hot air or hot exhaust gases of an upstream process can be passed directly into the storage module 29 so that the sensible heat contained therein can be stored in the storage module 29 according to the invention without the u201c detour u201d through an air air heat exchanger since the conduit 24 opens downstream of the blower 4 into the second feed line 19 the blower 4 is not loaded with the high temperatures of the air or exhaust gases flowing through the conduit 24 the conduit 24 enables thus coupling of sensible heat of a gaseous medium air or exhaust gases at lower temperatures than in the heat exchanger 3 fig2 shows schematically discharging of the high temperature heat storage system according to fig1 a according to the invention discharging of the high temperature heat exchanger system according to the invention according to fig1 b is realized in the same way with closed flap 23 so that a separate description is not needed for discharging by means of blower 4 cold air from the environment at a temperature of less than approximately 50 u00b0 c is sucked in and supplied through the second feed line 19 and the open flap 10 to the storage module 29 the flap 11 is closed during discharging by means of perforated metal plates 7 or lances the cold air is distributed within the housing 16 and passed through the storage medium 6 where it absorbs the heat the heated air exits then the store via.
