Abstract

PURPOSE:To eliminate unnecessary electric power consumption, by maintaining the relative moisture at a level, at which automatic mould growth hardly occurs, and not performing unnecessary operation of a humidifying machine at the time of low temperature. CONSTITUTION:A detecting sensor section 2 detects the temperature T=Ti and relative moisture H in an underground room and relative moisture data Hi below the mould growing lower limit corresponding to the detected temperature T=Ti are read out from the storage element 4 of a moisture controlling circuit 3. Then the detected relative moisture H is compared with the relative moisture data Hi read out from the storage element 4 and, when H/Hi, a signal is sent to a humidifying machine 5 from the moisture controlling circuit 3 so as to operate the machine 5. When H<=Hi, the detected relative moisture H is compared with humidifying machine stopping relative moisture data Hi' corresponding to the relative moisture data Hi read out from the storage element 4 and, if H<=Hi', the humidifying machine 5 is stopped.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for controlling humidity in underground storage.

(Prior art) In the conventional humidity control force method, the target set relative humidity when controlling the indoor relative humidity by starting and stopping the humidifier is:
It remained constant regardless of temperature.

(Problem to be Solved by the Invention) The disadvantage of using the prior art is that if the target set relative humidity is 70% RH, the oil in the mold growth area shown in Section 4 will be removed indoors. Even if the indoor relative humidity is below 70% when the temperature of Regardless, mold is likely to grow indoors. Also, if the target relative humidity setting was 60%, mold would not grow indoors regardless of the indoor temperature, but in winter when the indoor temperature is low, the indoor absolute humidity would be extremely low. It becomes smaller and dries, giving a bad impression V to the stored items.

(Predetermined Means, Effects, and Examples for Solving the Problems) An implementation configuration of the present invention aimed at solving the above problems is shown in FIG.

In Figure 1, 1 is the basement that is subject to humidity control, 2
3 is a humidity control circuit; 4 is a memory element 5 is a humidity controller.

First, in FIG. 1, the relative humidity data below the lower limit of mold growth according to the temperature as shown by the one-point chain in FIG. Store it in memory area M.

Next, details of the humidity control method of the present invention will be explained with reference to FIG.

In the third area, first, the typical temperature and relative humidity detection sensor in the basement shown in Fig.
i and the relative humidity Hi, and then the relative humidity data Hi f below the lower limit of mold growth corresponding to the basement temperature T = T i detected from the storage element 4 of the humidity control circuit 3.
read out. Here, the detected basement relative humidity H is compared with the relative humidity data read from the storage element 4, and if H>Hi, the humidity control circuit 3 sends the humidity controller 5 to operate the humidity controller 5. send a signal to.

If H≦Hi, the humidity adjustment a! corresponds to the detected basement relative humidity H and the specific relative humidity data Hi read from the storage element 4. Compare the stop relative humidity data Hi' and find H5.
In the case of Hi, a signal is sent from the humidity control circuit 5 to the humidity controller 5 to stop the humidity controller 5. Thereafter, the above-mentioned operation is repeated as shown in FIG. 6 to control the relative humidity in the basement and maintain it at a relative humidity below the lower growth limit depending on the temperature in the basement.

In the above, the humidity controller stop relative humidity data H1' corresponding to the relative humidity data Hi read from the memory element 4 is H
The humidity control method of the present invention can be realized by calculating it from i or by storing it in a memory in advance and reading it out.

(Effects of the Invention) According to the present invention, the relative humidity in a container or room whose temperature is to be controlled can be automatically maintained in a state where mold growth is difficult to occur at any temperature, which is sanitary. Furthermore, since unnecessary operation of the humidity controller is not performed at low temperatures, the container or the items stored in the room do not dry out at low temperatures, and furthermore, there is no unnecessary power consumption due to operation of the humidity controller, which is economical.
