Abstract

PURPOSE:To realize the directly regenerative system, which can at the same time be used for dehumidifying during the day, by a constitution wherein dehumidifying units containing dehumidifying agent, which are covered by movable reflectors, and those, which are receives both the direct sunlight and the light reflected by the movable reflectors, are separatedly arranged so as to be able to be changed-over from one group of units to the other group of units. CONSTITUTION:Dehumidifying units 1a-1d are separated into one group of the units, each of which is covered by movable reflectors from both sides and the other group of the units, each of which is open and receives the light reflected from the movable reflectors covering the adjoining dehumidifying units, so as to be able to be changed-over from the one group of units to the other group of units by the actions of the movable reflectors 4a-4e. The sunlight reaches directly and, in addition, after being reflected by the movable reflectors 4b-4e to the open dehumidifying units 1b and 1d so as to raise the temperature in containers 2 by the solar heat, resulting in evaporating the moisture contained in dehumidifying agent and consequently regenerating the agent. On the other hand, no temperature rises occur in the dehumidifying units 1a and 1c, because the units 1a and 1c are covered by the movable reflectors 4a-4d. Moist indoor air to be treated is led in the interior of the dehumidifying units 1a and 1c so as to be dehumidified at the interiors and raised the temperature by the heat of adsorption and consequently to be led outside in the form of dry air.

Description

[Detailed description of the invention] (a) Industrial application field This invention relates to a dehumidifying structure that utilizes solar heat for regeneration.
For example, it is used by being incorporated into a cooling device.

(B) Prior art A device that regenerates dehumidifying agents such as silica gel, zeolite, and lithium chloride using a heat source such as a heater or hot water to extract dry air again is widely used as an industrial dehumidifying device in the textile and food industries. . In recent years, solar heat dehumidification devices that use solar heat as a heat source have been actively researched.

Direct regeneration methods and indirect regeneration methods are known as methods for regenerating dehumidifiers using solar heat as a heat source. In the direct regeneration method, a heat collector and a dehumidifier filling tank are integrated, and when the temperature of the dehumidifier that receives direct sunlight increases, the moisture contained in it evaporates and is regenerated, and once regeneration is complete, the air flow path is closed. This method introduces humid air, dehumidifies the moisture contained in the air, and extracts dry air. On the other hand, the indirect regeneration method uses a heat collector to circulate a heat source such as hot water to the dehumidifier filling tank and raise its temperature.When the regeneration is complete, the heat source flow path is switched and the dehumidifier is used in another system. Use it to regenerate the filling tank. After the regeneration is completed, the filling tank continues to dehumidify the humid air.
The process of regeneration and dehumidification is repeated intermittently. The direct regeneration method is efficient because the dehumidifier can be directly heated by sunlight, and it also has the advantage of being inexpensive because the dehumidifier can be formed integrally with the heat collector. However, direct regeneration of dehumidifier requires an intermittent cycle with long intervals of regeneration during the day and dehumidification at night, which requires a large amount of dehumidifier, which poses problems such as high cost and increased weight, which is a major practical obstacle. It became.

(c) Purpose of the invention This invention was developed in view of the above circumstances, and aims to provide a dehumidifying structure that uses a direct regeneration method, can be used for dehumidification even during the day, and has excellent regeneration efficiency. be.

2) Structure of the invention This invention provides a dehumidification unit containing a built-in dehumidifier.
It has a structure that can be switched between one covered with a movable reflector and another that receives sunlight directly and also receives the reflected light from the movable reflector.The more detailed structure is that it absorbs solar heat. A plurality of dehumidifying units each filled with a dehumidifying agent whose dehumidifying function is regenerated by solar heat are installed in a container, and the lower end is rotatably supported between the dehumidifying units, with reflective surfaces on both sides. A movable reflector is installed, and every other dehumidifying unit is covered with a movable reflector from both sides and performs dehumidifying operation, and a group of dehumidifying units that are opened and exposed to direct sunlight or even adjacent This dehumidification structure is configured to be switchably separated into a dehumidification unit group whose dehumidification function is regenerated by receiving sunlight reflected from a movable reflector that covers the dehumidification unit.
