Title:
CHEMICAL HEAT STORAGE DEVICE
Document Type and Number:
Japanese Patent JP2018169118
Kind Code:
A
Abstract:
To provide a chemical heat storage device which can reduce unevenness in an adsorption amount of a reaction medium of an adsorbent by a position inside an adsorber.SOLUTION: In a chemical heat storage device, a second adsorbent 19B is arranged further outside in an adsorber 13 than a first adsorbent 19A. As the second adsorbent 19B outside has a high heat radiation property, the temperature hardly becomes high compared to the first adsorbent 19A. Here, the second adsorbent 19B has an adsorption amount maximum increase pressure region further on the high pressure side than the first adsorbent 19A. Therefore, in a state where a pressure of the adsorber 13 is low immediately after start of a regeneration reaction, before the temperature of the first adsorbent 19A becomes high, the first adsorbent 19A adsorbs ammonia concentrically. When time elapses and a pressure in the adsorber 13 comes into a high state, the second adsorbent 19B whose temperature is low and which has an adsorption amount maximum increase pressure region on the high pressure side adsorbs ammonia concentrically, and a sufficient amount of reaction medium can be adsorbed.SELECTED DRAWING: Figure 2
