Title:
CHEMICAL HEAT STORAGE DEVICE
Document Type and Number:
Japanese Patent JP2018017434
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a chemical heat storage device capable of detecting abnormality of the device.SOLUTION: A chemical heat storage device 7 includes a temperature sensor 15 detecting a temperature of an adsorber 10, a pressure sensor 16 detecting a pressure of the adsorber 10, a first calculation portion 18 calculating an increase amount of NHof the adsorber 10 on the basis of detection values of the temperature sensor 15 and the pressure sensor 16, an increase temperature estimation portion 19 determining an estimation value of the increase temperature of the adsorber 10 in recovering NHto the adsorber 10 from a reactor 9 on the basis of the increase amount of NHof the adsorber 10, a second calculation portion 20 calculating an actual measurement value of the increase temperature of the adsorber 10 in recovering NHto the adsorber 10 from the reactor 9 on the basis of the detection value of the temperature sensor 15, and an abnormality determination portion 21 comparing the actual measurement value of the increase temperature of the adsorber 10 and the estimation value of the increase temperature of the adsorber 10, then determining abnormality when the difference between the actual measurement value of the increase temperature of the adsorber 10 and the estimation value of the increase temperature of the adsorber 10 is larger than a threshold value.SELECTED DRAWING: Figure 1
