Title:
CHEMICAL HEAT STORAGE DEVICE
Document Type and Number:
Japanese Patent JP2017075739
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a chemical heat storage device capable of preventing liquefaction of a reaction medium in an adsorber while planning energy saving.SOLUTION: A chemical heat storage device 10 includes: a reactor 11 containing a reaction material 15 which generates heat through chemical reaction with NH3; an adsorber 12 containing an adsorbent 16 which can adsorb and desorb NH3; a heat exchange section 25 which performs heat exchange between NH3 in the adsorber 12 and outside air; an air blower 19 for blowing air to the heat exchange section 25; a temperature sensor 20 for detecting a temperature in the adsorber 12; a pressure sensor 21 for detecting a pressure in the adsorber 12; a storage section 22 for storing data of a pressure threshold curve corresponding to a saturated vapor pressure curve of NH3; and a control section for controlling the air blower 19 so as to accelerate heat exchange between NH3 in the adsorber 12 and the outside air when the pressure in the adsorber 12 detected by the pressure sensor 21 is equal to or higher than a pressure threshold in accordance with the temperature in the adsorber 12 detected by the temperature sensor 20 in the pressure threshold curve.SELECTED DRAWING: Figure 1
