Thermal storage system, thermal storage container, thermal storage device using thermal storage container, and warm air device using thermal storage device

Abstract

Provided are a thermal storage system, thermal storage container, and thermal storage device using said thermal storage container that enable the amount of heat generated and amount of heat transported to be enhanced with a simple configuration. The thermal storage system uses a thermal storage container that comprises: a tubular body; an adsorbent material that is housed in the tubular body, generates heat through adsorption of a substance to be adsorbed, and absorbs heat through desorption of the subject to be adsorbed; and a channel penetrating through the tubular body in a long-axis direction. In the system, included is a diffusion layer for diffusing a liquid-phase substance to be adsorbed from the channel to the adsorbent material; the substance to be adsorbed is transported to the channel; the substance to be adsorbed is transported to the diffusion layer; some of the substance to be adsorbed having been transported to the diffusion layer is adsorbed onto the adsorbent material;the adsorbent material releases heat; and the remainder of the substance to be adsorbed is evaporated by the heat and becomes a heat transport fluid.

Description

technical field [0001] The present invention relates to a thermal storage container using an adsorbent capable of utilizing heat released and absorbed when an adsorbent (such as zeolite) adsorbs an adsorbate (such as water, etc.) and a thermal storage device including the thermal storage container. The function of absorbing heat when the adsorbate (for example, water, etc.) desorbs, repeats heat generation and heat storage. Background technique [0002] In recent years, studies have been made on the storage and utilization of waste heat in industrial equipment and the like, particularly heat storage systems for storing and using waste heat obtained from engines of automobiles. [0003] For this, as Figure 8 As shown, a heat storage container 6 is proposed, wherein a chemical heat storage material composite including a chemical heat storage material 62 of powder and a foaming expansion material 63 arranged adjacent to the chemical heat storage material 62 is accommodated in ...

AI Technical Summary

Problems solved by technology

[0004] However, in the heat storage container 6 of Patent Document 1, it is necessary to separately provide the reaction flow path 64 for supplying water vapor and the heat exchange flow path 66 for supplying the heat exchange medium, so there is a problem that the piping configuration is complicated.

In addition, due to the complexity of the piping structure, the amount of chemical heat storage material 62 that can be mounted on the heat storage container 6 decreases, so there is a problem that the heat utilization per unit volume of the heat storage container 6 (heat storage density) decreases.

[0005] In addition, the temperature (heat storage temperature) required for heat storage of chemical heat storage materials is as high as 350°C or higher, and there is a problem that it is difficult to store heat depending on the location where the heat storage container is placed.
