Description

[Detailed description of the invention]

In the present invention, a dehumidifying body composed of a member containing a moisture absorbent and an adsorbent is regenerated by heated air. The present invention relates to a dehumidifier that is used to perform dehumidification operations. This type of dehumidifier: The main factors that affect the dehumidification efficiency (under foot humidity) are (1) regeneration temperature
i', (2) The dehumidification/regeneration time of the dehumidifier, that is, the number of rotations of the dehumidifier in the case of a rotating bed type σ dehumidifier, and the dehumidification/regeneration switching time (b2) in the case of a fixed bed type dehumidifier. Therefore, when dealing with fluctuations in dehumidification load, consideration must be given to these seven factors.However, in conventional dehumidifiers of this type, the dehumidification efficiency is controlled using only the amount of regenerated heat. It is easy to cause a decrease in the

[There was a drawback that the durability of the dehumidifying body and the equipment σJ 111rt was reduced due to the insufficient regeneration temperature. The reason for this is to talk about the case of a rotating bed type dehumidifier that uses molecular sieves as an adsorbent for the dehumidifier. First, the regeneration temperature is 1508C or lower, as shown in Figure 7, the dehumidification efficiency decreases rapidly. to Therefore, if the amount of regenerated heat is reduced in response to the dehumidification load, the regeneration temperature will be 9.5F or 9.5F if the regeneration air volume is 1 l/JF. There is a risk that the dehumidification efficiency will decrease, and on the other hand, if the amount of raw heat increases, the regeneration temperature will become extremely high, which will reduce the durability of the isobama, the dehumidifying body, and the cost of communication fees. Next, as for the rotation speed of the dehumidifier, as shown in Fig. 2, the maximum rotation speed of each dehumidifier depends on the amount of heat produced. 1) When the amount of raw heat is changed, the dehumidification efficiency inevitably decreases.Therefore, the present invention aims to control the dehumidification/regeneration time of the dehumidifier in conjunction with the control of the amount of regenerated heat. By doing so, the main purpose is to improve the dehumidification efficiency, and furthermore, by controlling the regeneration air volume in conjunction with the control of the regeneration heat amount and keeping the regeneration temperature constant, the dehumidification efficiency is prevented from becoming low. The purpose of this is to improve the durability of dehumidifiers, etc. Below, an explanation will be given of an embodiment shown in Figs. 3 and 3. This embodiment uses gaseous fuel for regeneration. , dehumidifier l
