Description of the Related Art As an air conditioner capable of adjusting humidity, for example, in an environmental test apparatus, a dry-bulb and wet-bulb temperature detector is provided above a room to be air-conditioned to detect temperature and humidity, and a humidifier is provided below the room. The humidification output is controlled so that the indoor humidity becomes the target humidity. In such a device, the wick is placed on the wet bulb temperature sensor, the wick is immersed in the water of the wick pan, the wick absorbs the water to detect the wet bulb temperature, and a float tank for detecting the water level is connected to the wick pan. And water is replenished so that the water level is maintained. Further, a float tank for detecting the water level is also connected to the humidifying dish of the humidifier, and water is supplied so that the water level of the humidifying dish is maintained. In this case, when the water level of the humidification water float tank drops, water is supplied to the humidification dish via the solenoid valve from the water system of the wick pan through a water level difference,
When the water level of the wick water float tank is lowered by this water supply, a water circuit that replenishes the wick pan with new water by a water supply tank and a water supply pump is often used.

Then, the water level will be restored by the makeup water. As a result, most of the water in the wick pan is replaced with new water having a large difference from the original water temperature, and the temperature of the water supplied to the wick changes greatly. Then, the wet bulb temperature fluctuates accordingly.

According to this, when the water supply is started as shown by the triangle, the water in the wick pan falls, the suction of the water of the wick is temporarily stopped, the wet bulb temperature t rises, and then a new fresh water temperature is obtained. When the water is replenished, the wet-bulb temperature t decreases due to a decrease in the temperature of the water sucked up by the wick, and then returns to a normal state. Therefore, the conventional water circuit has a problem that the wet bulb temperature fluctuates considerably.

(B), whereby the residual water portion 2a that can secure the water level L 3 to the height of the weir 21 at its distal end side is formed. The height of the weir 21 is determined so that the amount of water in the remaining water portion is appropriate as described later. The wick 1 is desirably arranged so that the lower end portion is immersed in the remaining water portion 2a.

する。According to the water circuit for adjusting humidity as described above, water is supplied to the humidifying dish and the wick pan as follows. When the environmental test apparatus is operated and the humidifier 3 is also operated, and the water in the humidifying dish 31 evaporates and is circulating in the room to adjust the humidity, the humidification output increases and the evaporation amount of the humidifier rapidly increases. When the water level in the humidifying dish 31 drops to a predetermined low water level due to various causes, such as water vapor being discharged from the air circulation system due to indoor air supply and exhaust and ventilation, the humidifying water float switch 51 switches the water level to a predetermined low water level. Upon detection, the solenoid valve 6 is opened.

時間を必要とする。As a result, the water in the wick water float tank 4 and the wick pan 2 is dropped into the humidifying dish 31 via the piping system 9. During this time, when the water level in the tank 4 drops and becomes low, the water supply pump 7 starts, and the water in the water supply tank 8 is supplied to the piping system 9. However, due to the inertia of the water flowing downward, the time difference, and the large amount of water supplied to the humidifying pan, much of the water in the tank 4 and the wick pan 2 is dropped into the humidifying pan 31 and the water level of the wick pan is temporarily reduced. It takes a long time for the water level to recover with makeup water.

However, even if the water level is lowered, the water level up to the height of the weir 21 is secured in the remaining water portion 2a. As a result, low-temperature water newly replenished in the wick pan 2 and water having a temperature close to the temperature in the test chamber in the remaining water portion 2a are mixed, and a decrease in the water temperature of the portion where the wick 1 is immersed is suppressed. The fluctuation of the detected wet bulb temperature is suppressed and reduced.

される。Further, if the water in the wick pan is supplied to the humidifier by lowering the water level of the humidifier as in the water circuit to which the present invention is applied, the number of times of replacement of the water in the wick pan is increased, and the wick pan is increased. The water inside can be maintained in a state of good freshness. As a result, the propagation of dirt and germs on the wick and wick bread is suppressed, and an effect of preventing drying of the wick is produced. As a result, the residual water portion 2a
By providing the above, it is possible to enjoy the good effect of preventing the drying of the wick while solving the problem of the fluctuation of the wet bulb temperature. When the float tank 4 becomes a low water level due to evaporation of water from the wick 1 at a time different from the water level drop on the humidifier side, the water supply pump 7 starts to supply water to the float tank 4 and the wick pan 2. Is done.

ことができる。FIG. 2 shows a fluctuation state of the wet bulb temperature t when the water circuit for adjusting humidity is constructed as described above and is operated. The horizontal axis in the figure is time T, and the triangle is humidifying dish 31.
Represents the time when the water replenishment operation was performed due to the decrease in the water level.
According to this figure, the fluctuation width Δt of the detected wet-bulb temperature is reduced due to the effect of the residual water portion 2a as described above, and is 1/1 of the fluctuation width Δt ′ shown in FIG. 4 when the present invention is not applied.
It turns out that it is about 2 or less. This is because the water is secured in the remaining water portion 2a, so that the lower end portion of the wick 1 does not run out of water and the wick can continuously draw up water, and the temperature of the water decreases less. Then, if the wet bulb temperature fluctuates as shown in FIG. 2, the control output of the humidifier 3 hardly changes, and stable humidity control can be performed.

In (a), a step h is provided between a portion of the wick pan 2 in which the wick 1 is immersed and a pipe portion for supplying water, and a step drop portion on the tip side is a residual water portion 2a. The residual water portion 2a may be formed so as to have an inclined bottom as shown by a two-dot chain line. (B)
In this example, the leading end side is made uneven so that the concave portion becomes the remaining water portion 2a. In this case, it is desirable to arrange the wick 1 such that the lower end portion thereof is in contact with the remaining water portion 2a so that even when only the remaining water is present, it is possible to suck up water to some extent. As described above, the remaining water portion 2a may have a structure in which an appropriate amount of water remains when the water level in the wick pan 2 drops, and an appropriate shape other than those illustrated in FIGS. 1 and 3 is employed. be able to.
