Description

  The present invention relates to a humidifier used in, for example, a factory of a precision machine industry or a clean room.

  In precision machinery factories and clean rooms, it is necessary to maintain a constant room environment such as temperature and humidity, and such humidifiers for the purpose of constant temperature and humidity in the room include air flow in housings and casings. A heating coil, a cooling coil, a vaporizing humidifier, a dew point sensor or an absolute humidity sensor, and a blower are arranged on the road from the air intake side (see, for example, Patent Document 1). This vaporizing humidifier consists of a humidifying module that drops water from the water supply pipe onto the humidifying material so that the surface of the humidifying material becomes a wetted surface, and is detected by a dew point sensor. The heating and cooling coil is controlled so that the dew point after humidification is constant, so that humidification is performed. The heating / cooling coil proportionally controls the heating / cooling amount (for example, the flow rate of cold water or hot water) based on the dew point temperature detected by the dew point sensor.

  In general, the amount of water supplied to the vaporizing humidifier is the amount of water including the amount of water used for cleaning the humidifying material in addition to the amount of humidification required to keep the room constant humidity. The water used for cleaning the humidifying material flows into the humidifying material surface as the vaporizing humidifier captures and collects dirt dirt and other deposits in the air, as with the wet filter. Thus, the water is necessary to clean the surface of the humidifying material so as not to get dirty, and is used approximately 1.5 to 2 times the required maximum humidifying amount.

Necessary humidification amount is, for example, 0 ℃ DB / 40% RH in winter, 25 ℃ DB / 60% RH in summer, 15 ℃ DB / 40% RH in mid-term (spring, autumn) It fluctuates with changes in temperature and humidity due to changing seasonal factors and weather factors such as sunny, cloudy, and rainy. For this reason, the amount of water supply is determined by adding the amount of water required for cleaning the humidifier to the required amount of humidification (required maximum humidification amount) based on the winter air conditions where the amount of humidification is the largest. It was used with a constant amount of water without being controlled.
JP 2001-317795 A

However, since the required humidification amount varies depending on seasonal factors and weather factors as described above, the maximum humidification amount is always required even during the humidification season, and water supply exceeding the required water supply amount for the required humidification amount is limited. Waste water was generated.
Recently, there are factories that require humidification in the summer, such as factories in the precision machinery industry and clean rooms, and humidification is required throughout the year. There was a problem.

  In general, the absolute humidity is higher in the summer than in the winter, so a humidifier that performs external air treatment can reduce the amount of water supplied to the humidifier in the summer, so the water supply is adjusted manually. There was also a case. However, in order to reduce waste water efficiently, it is necessary to constantly adjust the amount of water supply, which is a troublesome manual operation and is complicated. In addition, there are factories where the orifices and valve openings are manually changed or adjusted based on the setting table for the amount of water supplied so as to respond to changes in the season and air conditions. There was a problem that it took.

  When adjusting the water supply amount in this way, the conventional water supply control method using an orifice or nozzle can only make the water supply amount a constant flow rate, and evenly distribute multiple nozzles and multiple nozzles for water supply to the humidifying material. When a small flow rate is to be controlled, the dropping state from individual nozzles or small holes and the amount of discharged water vary, resulting in a non-uniform dripping state. In addition, with conventional orifices and constant flow valves, there is a lower limit for controlling the water supply amount to a small flow rate and it cannot be reduced to a small flow rate, so there is a limit to water supply at a continuous and uniform small flow rate to the humidifier. there were.

Also, recent humidifiers can adjust the air volume based on air conditions (temperature and humidity conditions) and arbitrary settings. Since the humidification capacity of the vaporizing humidifier changes proportionally depending on the amount of air passing through, the humidification amount decreases when the air volume is adjusted and set to a value lower than the maximum air volume. There was a case where waste water was generated because the amount of water supplied to the material was constant.
Furthermore, since the conventional humidifier cannot be controlled according to the amount of water supply suitable for the amount of humidification associated with both changes in air conditions (temperature and humidity conditions) and air volume, waste water is generated as well. When pure water is supplied to a humidifier as in a factory or a clean room, there is a problem that the cost of wasted water is enormous.

  Accordingly, the present invention provides a humidifier using a vaporizing humidifier that automatically controls the amount of water supplied to the vaporizing humidifier according to the required humidification amount that changes due to seasonal factors, weather factors, etc. It is an object of the present invention to provide a humidifier that can be reduced, is easy to operate, saves energy, and has a low running cost.

Next, the operation of the humidifier according to the present invention will be described with reference to FIGS.
As shown in FIG. 3, a target dew point temperature (for example, point X ′ in FIG. 2) after humidification by the vaporizing humidifier 1 is set as a dew point setting value. The water supply amount control mechanism 7 compares / calculates the dew point detected by the intake-side humidity detector 6 with this dew point set value, and calculates the required humidification amount. Next, the water supply amount control mechanism 7 outputs a control signal for supplying a water supply amount corresponding to the required humidification amount, and controls the opening degree or the open / close time of the water supply valve 9 to supply to the vaporizing humidifier 1. Control the amount of water supply.

Further, the humidification amount is controlled as follows.
In FIG. 2, when humidifying from point A to point X, the heating / cooling control mechanism 3 controls the opening degree of the control valve 5 based on the detected value of the supply side humidity detector 2, and the heating / cooling coil 4. To heat the air before humidification to point Y. Next, the air humidified by the vaporizing humidifier 1 to which the necessary amount of water is supplied is in a state of point X ′. Furthermore, it can control to the state of the point X by heating the air after humidification with a heating coil.

A specific water supply amount setting and control method is performed as follows.
[Control Example 1]
In air conditioning for factories such as clean rooms, air conditioning that generally introduces a lot of outside air and mixes with indoor air is performed, and the indoor temperature and humidity are set to a constant value of 20 ° C DB / 50% RH throughout the year. In many cases, the water supply is controlled as follows.
In this control example, the water supply amount control mechanism 7 calculates the difference between the absolute humidity with respect to the desired humidity of the air supply port 12 and the absolute humidity on the air intake port 11 side as the required humidification amount.
Although the humidity to be processed varies depending on the season such as winter and summer and the weather, the required humidification amount can be obtained from the state of the inlet air of the vaporizing humidifier 1 detected by the intake-side humidity detector 6. For example, the air condition detected by the intake side humidity detector 6 is 0 ° DB / 40% RH in winter (point A in FIG. 2) and 15 ° DB / 40% RH in the intermediate period (point B in FIG. 2). ), If the summer is 25 ° C DB / 60% RH (point C in Fig. 2) and the factory temperature / humidity is 20 ° C DB / 50% RH (point X in Fig. 2), then the winter A point from Fig. 2 The required absolute humidity (kg / kgDA) is “X′−A ′”, and the required humidification amount can be obtained by W = SG × V × (X′−A ′). Here, W: humidification amount (kg / h), V: air volume (m 3 / h), SG: air density (1.2 kg / m 3 ).
Therefore, by detecting the inlet absolute humidity (dew point temperature or temperature / humidity) of the vaporizing humidifier 1 by the intake side humidity detector 6, the water supply amount control mechanism 7 determines the absolute humidity (dew point set value) for the desired temperature. The required humidification amount can be obtained by performing the comparison calculation, and the required water supply amount to the vaporizing humidifier 1 can be set.

In addition, at the B point in the intermediate period, the required absolute humidity is “X′−B ′” from FIG. 2, and the required humidification amount can be obtained by W = SG × V × (X′−B ′). It should be noted that humidification is unnecessary because the desired absolute humidity is exceeded at the summer C point. However, if the heating / cooling coil 4 causes excessive dehumidification, humidification is required as in the intermediate period or winter period, and the humidity state is detected by the humidity detector 6 in the same manner to obtain the humidification amount. Can do.
When the required humidification amount is obtained in this way, the water supply amount is controlled in accordance with the humidification amount, so that an appropriate water supply amount is obtained and not only an ideal humidified water supply but also control is performed so as not to discharge drain water. Can also save water and save energy.
Further, the vaporizing humidifier 1 supplies an excess amount of water corresponding to the amount of humidification as cleaning water in order to remove dirt such as dust adhering to the surface of the humidifying material and other deposits.

Further, the water supply amount control mechanism 7 calculates a ratio of the required humidification amount to the maximum humidification amount of the vaporizing humidifier 1 and controls the water supply amount to the vaporizing humidifier 1 according to the ratio. it can.
Assuming that the humidification amount at point A in winter is the maximum humidification amount, the control of the water supply amount is (X′−inlet absolute humidity) / (X′−A ′) × 100% ratio of the required humidification amount to the maximum humidification amount ( Water supply rate) can be obtained, and by multiplying the maximum humidification amount in winter by this ratio, an appropriate water supply amount can be obtained.

[Control Example 2]
Moreover, when using a vaporization type humidifier with high saturation efficiency, for example, if the humidification control dew point range (−1 to 15 ° C. DP) is set as the humidification amount (100 to 0%), dew point −1 to 15 ° C. DP is supplied to the water. Water supply amount control is performed corresponding to the amount of 100 to 0% RH. That is, when the intake side humidity detector 6 detects -1 ° C DP (including -1 ° C DP or less), the water supply amount is 100% of the maximum water supply amount (1.5 to 2 times the maximum humidification amount). The water supply is stopped when 15 ° C. DP (including 15 ° C. DP or more) is detected. In addition, between -1 and 15 ° C DP, proportional control is performed with absolute humidity corresponding to each dew point temperature, and when 8 ° C DP, which is the middle, is detected, 50% of the maximum water supply amount is supplied. The amount of water supply is controlled.

  Specifically, since the amount of water supply is controlled by intermittently operating the electromagnetic valve of the water supply valve 9, for example, if the control is 50%, the opening time and the closing time of the electromagnetic valve are controlled to be 50% each. Actually, if one cycle of the intermittent (open / close) cycle of the solenoid valve is 1 minute, the solenoid valve repeats a cycle of maintaining the closed state for 30 seconds after opening for 30 seconds. By detecting the inlet air condition in real time with the intake-side humidity detector 6 and performing this control operation, it is possible to set an appropriate water supply amount and supply water appropriately, eliminating wasted water and greatly saving water and saving energy. Can contribute.

Next, a second embodiment will be described with reference to FIGS.

Next, Example 3 will be described with reference to FIG.
In the humidifying device of the first or second embodiment, the vaporizing humidifier 1 may be provided in multiple stages in the air flow path 10.
As shown in FIG. 7, in the multistage humidification method, the vaporization humidifier 1 on the air supply port 12 side approaches the saturated state by the first vaporization humidifier 1, so that the second and subsequent humidifications are performed. Compared to the first stage, the amount may be a small amount of humidification, and a small amount of water supply is sufficient. Accordingly, the water supply amount of the second-stage vaporizing humidifier 1 is set to, for example, 1/10 of the first-stage water supply amount, and water can be further saved by supplying a water amount proportional to the small water supply amount.

Next, a fourth embodiment will be described with reference to FIGS.
In the embodiment shown in FIG. 8, the humidifier includes an evaporative humidifier 1 provided in the air flow path 10 between the air intake port 11 and the air supply port 12, and an air volume for detecting the air volume in the air flow path 10. It comprises a detector 14 and a water supply amount control mechanism 7 provided in connection with the air flow detector 14, and the water supply amount control mechanism 7 calculates the required humidification amount based on the detection value of the air flow detector 14 and vaporizes it. It is comprised so that the amount of water supply to the type humidifier 1 may be controlled.

  The air volume detector 14 can use sensors such as an air volume sensor, a wind speed sensor, and a dynamic pressure sensor. As described above, the humidification amount can be obtained by W = air density × air amount × absolute humidity amount. Therefore, if the air density and the absolute humidity amount are constant, the humidification amount is proportional to the air amount. Therefore, the water supply amount control mechanism 7 controls the opening degree or opening / closing time of the water supply valve 9 based on the air flow detected by the air flow detector 14 and proportionally controls the water supply amount to the vaporizing humidifier 1.

Further, the water supply amount control mechanism 7 calculates the required humidification amount by multiplying the maximum humidification amount by the ratio of the detected air amount to the maximum humidification amount in the maximum air amount.
The water supply amount control mechanism 7 is provided with an operation control unit that controls the water supply amount by a signal from the air flow detector 14 and a water supply amount adjustment unit that adjusts the water supply amount by this operation control unit. Based on the signal from the air volume detector 14, the calculation is performed by detecting and calculating the air volume ratio of the value from the air volume detector 14 with respect to the designed maximum air volume range. For example, if the design air volume is in the range of 10000 m 3 / h at the maximum and the detected value from the air volume detector 14 is 6000 m 3 / h, the water supply amount is simply controlled so that the flow rate is 60% in proportion. The water supply amount can be controlled by the water supply amount adjustment unit.
The configuration of the other parts is the same as in the above embodiment.

  In addition, as shown in FIG. 9, the air volume detector may be constituted by a fan controller 16 and may be configured to detect the output of the blower 15 provided at the air intake port 11 and calculate the air volume. The fan controller 16 includes control devices such as inverter control and voltage control, and calculates the air volume from the relationship between the output value of the blower 15 and the output value at the maximum air volume.

Next, Example 5 will be described with reference to FIGS.
The humidifying apparatus shown in FIG. 10 is provided in the humidifying apparatus of the first embodiment by connecting an air volume detector 14 for detecting the air volume in the air flow path 10 to the water supply amount control mechanism 7. The required humidification amount is calculated based on the detection values of the inlet-side humidity detector 6 and the airflow detector 14, and the water supply amount to the vaporizing humidifier 1 is controlled. About each component, it is the same as that of said Example.

  In addition, as shown in FIG. 11, the air volume detector may be composed of a fan controller 16 and may be configured to detect the output of the blower 15 provided in the air intake port 11 and calculate the air volume. The fan controller 16 includes control devices such as inverter control and voltage control, and calculates the air volume from the relationship between the output value of the blower 15 and the output value at the maximum air volume.

Next, the operation of the humidifier of this embodiment will be described.
In the control based on the detection value of the air flow detector 14, as shown in FIG. 12, for example, the maximum design air flow (10000 m 3 / h) is set to 100%, and the proportional calculation is performed so as to be 50% when the air flow is 5000 m 3 / h. I do. Further, in the control based on the detection value of the intake side humidity detector 6, as shown in FIG. 2, for example, the required humidification amount at the A point in winter is set to the maximum humidification amount (100%), and humidification is not required. The X point of the value is 0%. Between the A humidification point corresponding to the A point and the X point, the proportion between the A ′ point and the X ′ point corresponding to the X point is proportionally calculated at the above-described ratio and output as a corresponding value.

  The water supply amount control mechanism 7 inputs the output calculated from the air volume and the dew point to the product calculator to obtain the product of both output values. For example, as shown in FIG. 12, when the output calculated from the dew point is 50% and the output calculated from the air volume is 50%, it is 0.5 × 0.5 = 0.25 by passing through the product calculator. Get an output of 25%. The amount of water supplied to the vaporizing humidifier 1 is controlled by controlling the opening or opening / closing time of the water supply valve 9 based on this output value.

  It is also possible to supply a water amount obtained by adding cleaning water for cleaning the vaporizing humidifier 1 to the required humidification amount calculated and calculated in this way. In addition to adding an arbitrary constant water amount of 50 to 100% of the maximum humidification amount, the cleaning water amount can be controlled in accordance with the ratio of the required humidification amount to the maximum humidification amount.
