Referring to fig. 1 and 5, the control module 9 includes a Proportional-Integral and Derivative Control (p.i.d. controller) and a humidity sensor 91, wherein the humidity sensor 91 is electrically connected to the control module 9, and is capable of adjusting the operation of the humidifying device 2 by detecting the ambient humidity to generate corresponding status signals, and the control module 9 is capable of receiving the status signals generated by the first liquid level sensor 12, the second liquid level sensor 23 and the humidity sensor 91 respectively, so that the control module 9 generates a corresponding execution signal to control at least one of the switch valve 4, the water replenishing device 1, the flow control valve 6, the humidifying device 2 or the drain valve 8 through logic judgment.

Referring to fig. 1, 4 and 5, the second tank 21 holds water having a temperature at the first temperature (e.g. boiling point) and keeps a high water level, and the lowest water level of the first tank 11 is higher than or equal to the highest water level of the second tank 21, i.e. the first tank 11 also keeps a high water level, and when water flows into the first tank 11 from the source side, the water inflow of the water replenishment device 1 is less than 20% of the residual water of the water replenishment device 1, and the water temperature variation in the first tank 11 is reduced by a small amount of water replenishment and by keeping a high water level; furthermore, after the water in the second tank body 21 is heated to form water vapor, part of the water vapor can face the bottom surface direction of the first tank body 11, and the heat of the water vapor can be directly transferred to the first tank body 11 through the heat conducting material of the first tank body 11, so that the water temperature in the first tank body 11 can approach the water temperature of the second tank body 21, and when the water is conveyed to the second tank body 21, the water pipe 5 with an adiabatic structure can keep or substantially keep the water temperature, and through the design of small pipe diameter and the matched use of the flow control valve 6, the influence of the fluctuation of the inflow water temperature on the evaporation amount of the humidifying device 2 can be effectively avoided, and the stable humidifying amount can be generated.

In order to keep the water in the second tank 21 in a boiling state, the control module 9 transmits a first execution signal to control both the switch valve 4 and the flow control valve 6, the first execution signal includes controlling the switch valve 4 to be opened, immediately closing the flow control valve 6, simultaneously detecting the water level in real time through the first liquid level sensor 12, the first liquid level sensor 12 transmits a first state signal to the control module 9, after finishing the water replenishing, mixing and steam preheating process, the control module 9 transmits a second execution signal to control the switch valve 4 and the flow control valve 6, the second execution signal includes controlling the switch valve 4 to be closed, and opening the flow control valve 6 after waiting for a first time, so as to ensure that the water temperature in the water replenishing device 1 is close to the water temperature in the humidifying device 2, prevent the water with lower temperature from flowing into the humidifying device 2, after the flow control valve 6 is opened, the water in the first tank 11 is conveyed into the second tank 21, a second time is required to complete the conveying of the water, and the flow control valve 6 is closed again after finishing the conveying process. Taking the first tank 11 having 3 liters (L) of water to be preheated at 80 degrees celsius as an example, the water to be preheated is expected to be heated to 90 degrees celsius to form steam preheated water, which requires about 125.4 kilojoules (kJ) of heat, and thus the first time is about 3 minutes; taking 1 liter (L) of steam-preheated water, the flow control valve 6 is adjusted to a flow rate of 0.2 liter/minute (L/min; lpm), the water in the first tank 11 is fed into the second tank 21 for about 5 minutes (i.e., the second time).

In addition, the electric heating rod 22 calculates the matched output power according to the humidifying precision (±0.3%rh) to match the control module 9 to achieve the high-precision humidifying specification, wherein the output power calculation formula of the electric heating rod 22 is as follows:

the humidification rate of the electric heating rod 22 (kg/hr))=change in humidity per Scale (kg/kg-Scale) x total Scale (Scale) x air density (kg/cubic meter (kg/m) ³ ) X air volume (cubic meter/min (m) ³ /min). Times.60 (minutes (min)).

In the case that the first liquid level sensor 12 of the water replenishment device 1 generates a low liquid level signal, the control module 9 generates a water replenishment signal to open the switch valve 4, so that water at the source side can be conveyed into the first tank 11; in the case that the first level sensor 12 of the water replenishment device 1 generates a high level signal, the control module 9 generates a water shut-off signal to close the on-off valve 4, so that the water at the source side stops being supplied to the first tank 11.

Under the condition that the ambient humidity is lower than a system set value, the control module 9 generates a humidification signal to increase the output power of the electric heating rod 22, and the humidifying device 2 can release water vapor in an accelerating way; under the circumstance that the ambient humidity is higher than the system set value, the control module 9 generates a dehumidification signal to reduce the output power of the electric heating rod 22 so as to reduce the release of water vapor from the humidifying device 2, and the control module 9 can receive the liquid level state signal generated by the second liquid level sensor 23 to confirm whether the humidifying device 2 maintains the high water level state, and under the circumstance that the second liquid level sensor 23 generates the low liquid level state signal, the control module 9 can transmit a stop signal to the electric heating rod 22 so as to stop the electric heating rod 22 from executing the heating action, thereby being capable of automatically protecting the high-precision humidifying equipment H; in the case that the second level sensor 23 generates a high level signal, the control module 9 will send an opening signal to the drain valve 8 to make the drain valve 8 open, so as to drain the excessive water in the second tank 21.

In summary, in the humidity control application of the precision humidifying device H in the precision air conditioning industry, the maximum efficacy is achieved by the minimized assembly composition through the ultra-precision or high-precision humidity control technology, the water temperature fluctuation range in the first tank 11 is reduced by the water mixing mechanism through the water supplementing device 1, meanwhile, the energy loss generated by heating the low-temperature water by the humidifying device 2 is saved, the water quantity flowing into the humidifying device 2 is regulated by the pipe diameter of the water pipe 5 and the flow control valve 6, the water temperature change caused by the cooling of the boiling water in the humidifying device 2 is reduced, and the stable humidifying quantity can be formed.

The above examples and/or embodiments are merely for illustrating the preferred examples and/or embodiments for implementing the technology of the present application, and are not limited in any way to the embodiments of the technology of the present application, and any person skilled in the art should be able to make some changes or modifications to other equivalent examples without departing from the scope of the technical means disclosed in the present application, but should still consider the technology or examples substantially identical to the present application.
