The second switching valve 6b and the fourth switching valve 6d are opened, the flow of the heat medium 7 is reversed (see the dotted arrow), and heat is stored in the latent heat storage material 2 on the thermometer T 1 side. The latent heat storage material 2 is used in the heat storage device. As shown in FIG. 3, the latent heat storage material 2 receives heat from the heat medium 7, melts at a constant temperature, and stores heat. It also solidifies at a constant temperature and radiates heat. In general, the latent heat storage material 2 has a low thermal conductivity, so that the latent heat storage material 2 is brought into direct contact with the heat medium 7 to perform heat exchange and enhance heat transfer efficiency. However, since the heat storage device 1 is of the packed bed type, in order to increase the capacity, a plurality of heat storage devices 1 each having a short heat medium passage path are arranged in parallel to increase the capacity, and a heat storage device of a heat storage system is provided. To increase the capacity. Also, by increasing the capacity, both pressure loss and heat medium flow rate increase are achieved.

る。FIG. 4 qualitatively shows the temperature change, the melting state change, and the heat medium temperature change of the latent heat storage material 2 by taking an example during heat dissipation. When the heat medium 7 is flowed in only one direction, the temperature difference between the latent heat storage material 2 and the heat medium 7 is large at the inlet of the heat storage device 1, and therefore the amount of heat radiation is large and the solidification rate of the latent heat storage material 2 is large. Is considerably larger than that at the outlet of the heat storage device 1, and finally, the latent heat storage material 2 at the inlet is completely solidified in the heat storage device 1 and becomes a two-phase state at the outlet. If such a state is continued, the temperature of the solidified latent heat storage material 2 at the inlet portion further falls below the melting point temperature, the average temperature difference between the latent heat storage material 2 and the heating medium 7 becomes small, and the heat storage efficiency is improved. descend.

2 is reversed (see the dotted line arrow in FIG. 2C) to prevent the average temperature difference between the latent heat storage material 2 and the heat medium 7 from decreasing as shown in FIG. 5, thereby improving the heat storage efficiency.

で、蓄熱効率を向上できる。As described above, in the exhaust heat utilization apparatus of the present invention, a plurality of heat accumulators are arranged in parallel in the heat storage system, so that the heat storage apparatus of the heat storage system can have a large capacity. Further, by increasing the capacity, both reduction of pressure loss and increase of heat medium flow rate can be achieved. Further, if the heat medium temperature at the inlet of each heat storage device is constant, as long as the heat storage material is in the two-phase state, the heat medium temperature also has a constant distribution regardless of time. However, for example, when radiating heat, near the heat storage inlet,
Since it completely solidifies quickly, the temperature of the heat storage material falls below the melting point,
This effect appears on the thermometer as a decrease in temperature. At this point, the first switching valve to the fourth switching valve are switched to reverse the flow of the heat medium to prevent the average temperature difference between the heat storage material and the heat medium from decreasing, so that the heat storage efficiency can be improved.
