THERMAL CIRCUIT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/238876
Kind Code:
A1
Abstract:
Provided is a heat regeneration system in which a heat source necessary for a process is regenerated with a waste heat. This heat regeneration system utilizes a hot waste heat and a cold waste heat discharged from a process to convert the hot waste heat and the cold waste heat respectively into a necessary high-temperature heat and a necessary low-temperature heat. This heat regeneration system is provided with: (a) a thermal amplifier 4 in which an adsorbent that utilizes a hot waste heat as an adsorption heat is stored; (b) a thermal battery 5 in which a latent heat storage material capable of storing an output heat from the thermal amplifier is stored; (c) a thermal transistor 2 in which evaporated water in a high-pressure absorber is absorbed in the absorption solution, a temperature-risen heat is extracted with a heat exchanger and is output as a high-temperature heat, water is evaporated with a low-pressure evaporator, a cold waste heat discharged from a low-temperature process 7 by the action of a steam latent heat is cooled to output a low-temperature heat, and the absorption solution is regenerated using a latent heat of the latent heat storage material; and (d) a thermal booster 3 in which the temperature of the high-temperature heat is risen by a hydration reaction of a chemical heat storage material, a heat is stored by a dehydration reaction of the chemical heat storage material using the high-temperature heat, steam generated by the dehydration reaction is condensed using the low-temperature heat to promote the regeneration of the chemical heat storage material, and a heat source necessary for the process is produced.
