Problems solved by technology

[0006] However, in the described existing humidity control device, it is considered that the amount of heat used to heat and restore the moisture-absorbing element may not be sufficient.
In particular, the refrigerant commonly used in existing humidity control devices, that is, R22 (CHClF 2 ) is used as the refrigerant in the refrigerant circuit, it is considered that there will be a problem that the heat for heating and recovering the moisture absorbing element cannot be obtained sufficiently, and as a result, the humidity control of the humidity control device Performance drop

[0049] First, the humidity control device according to the first embodiment will be described. The humidity control device according to the first embodiment is configured to switch between a dehumidification operation to supply dehumidified air to the room and a humidification operation to supply humidified air to the room. This humidity control device has a moisture absorption device (80) and a refrigerant circuit (100) which will be described in detail later, and is configured to perform batch operation. Here, referring to Figure 1, Figure 5 and Figure 6 , the structure of the humidity control device according to this embodiment will be described. As a supplementary note, in the description of this embodiment, unless otherwise specified, the terms "upper", "lower", "left", "right", "front", "rear", "near side" and "far side" "side" means the directionality when viewing the humidity control device shown in FIG. 1 from the front side.

Abstract

The amount of heat for thermal regeneration of an adsorber ( 80 ) is increased by making the sensible heat zone ( R ) for refrigerant ( 106 ) in a refrigeration cycle larger than that for R22.

Description

technical field [0001] The invention relates to a humidity control device for dehumidifying and humidifying air with a moisture absorbing device. Background technique [0002] As a humidity control device for adjusting the temperature and humidity of indoor air, a desiccant humidity control device utilizing the moisture adsorption effect of a desiccant has been known so far. [0003] For example, the desiccant humidity control device includes: a hygroscopic element that absorbs and desorbs moisture in the indoor air, and a refrigerant circuit that adjusts the temperature of the indoor air. The indoor air introduced into the desiccant humidity control device is humidified or dehumidified by the moisture absorbing element, and heated or cooled by the heat exchanger of the refrigerant circuit. The moisture-absorbing element that has absorbed moisture is restored by heating to restore the moisture-absorbing capacity of the moisture-absorbing element. [0004] The hygroscopic e...
