Description

Technical Field

[0001] This utility model relates to the field of air conditioning humidification control technology, and more specifically, to a combined air conditioning high-pressure micro-mist humidification control system. Background Technology

[0002] In the cigarette factory's production environment, the air conditioning system maintains stable air humidity in each workshop through micro-mist humidification technology. This system needs to be dynamically adjusted based on real-time humidity monitoring data to ensure the constant humidity requirements of the production environment. The water supply pipeline consists of seven parallel pipes of the same diameter, arranged in an orderly fashion behind the atomizing nozzles, internally delivering constant-pressure pure water. Each pipe corresponds to a set (10) of atomizing nozzles, and the humidification amount is controlled by opening and closing a corresponding solenoid valve. Theoretically, this design can achieve continuous adjustment of the humidification amount within the range of 0% to 100%, but the actual adjustment method is discrete—each time a solenoid valve is opened, the humidification amount increases by approximately 14.28% (i.e., a 1 / 7 adjustment step).

[0003] In actual production processes, humidification adjustments typically rely on manual real-time adjustments based on on-site humidity monitoring data. This operational mode presents two significant problems: First, manual intervention not only increases additional labor costs but also leads to unstable adjustment results due to the subjectivity of human operation. Second, existing humidification systems have low adjustment precision, only capable of adjusting in a fixed gradient of 14.28%. This crude adjustment method often results in the system being unable to accurately compensate when the ambient humidity is too low or too high, leading to over-adjustment—that is, after adjusting the humidification level, the ambient humidity will rapidly rise or fall, creating significant fluctuations and ultimately making humidity control difficult, failing to maintain it within the ideal range.

[0004] Therefore, there is an urgent need for a combined air conditioning high-pressure micro-mist humidification control system. Utility Model Content

[0023] like Figure 1As shown, the combined air conditioning high-pressure micro-mist humidification control system provided in this embodiment includes: a micro-mist humidification box 1 and a micro-mist humidification control cabinet 19 arranged in sequence. The micro-mist humidification box 1 is connected to the micro-mist humidification control cabinet 19 through a first pipe 11, a second pipe 12, a third pipe 13, a fourth pipe 14, a fifth pipe 15, a sixth pipe 16, a seventh pipe 17, and an eighth pipe 18 arranged in parallel. The first pipe 11, the second pipe 12, the third pipe 13, the fourth pipe 14, and the fifth pipe 15 are located inside the micro-mist humidification box 1. The sixth pipe 16, the seventh pipe 17, and the eighth pipe 18 are each equipped with a different number of micro-mist nozzles 2. The first pipe 11 is equipped with a first solenoid valve 3, the second pipe 12 is equipped with a second solenoid valve 4, the third pipe 13 is equipped with a third solenoid valve 5, the fourth pipe 14 is equipped with a fourth solenoid valve 6, the fifth pipe 15 is equipped with a fifth solenoid valve 7, the sixth pipe 16 is equipped with a sixth solenoid valve 8, the seventh pipe 17 is equipped with a seventh solenoid valve 9, and the eighth pipe 18 is equipped with an eighth solenoid valve 10.

[0024] The micro-mist humidification control cabinet 19 includes automatic and manual operation modes. The function of the micro-mist humidification control cabinet 19 is to drive the corresponding solenoid valve according to the humidification amount set by the system, and to adjust the humidification amount per unit time by controlling the opening and closing of the solenoid valve, thereby achieving higher control precision.

[0025] Furthermore, the number of micro-mist nozzles 2 corresponding to the first pipe 11 and the second pipe 12 is 10, the number of micro-mist nozzles 2 corresponding to the third pipe 13 is 20, the number of micro-mist nozzles 2 corresponding to the fourth pipe 14 is 5, the number of micro-mist nozzles 2 corresponding to the fifth pipe 15 and the sixth pipe 16 is 1, the number of micro-mist nozzles 2 corresponding to the seventh pipe 17 is 3, and the number of micro-mist nozzles 2 corresponding to the eighth pipe 18 is 50. This invention optimizes the original nozzle and pipe connection method, adjusts the number of nozzles connected to each pipe, and adds a new pipe. By combining and controlling the switching of different solenoid valves, fine adjustment of the humidification amount can be achieved, improving the system adjustment accuracy to ±1%.

[0026] Furthermore, the first solenoid valve 3 is located on the first pipe 11 between the micro-mist humidification box 1 and the micro-mist humidification control cabinet 19; the second solenoid valve 4 is located on the second pipe 12 between the micro-mist humidification box 1 and the micro-mist humidification control cabinet 19; the third solenoid valve 5 is located on the third pipe 13 between the micro-mist humidification box 1 and the micro-mist humidification control cabinet 19; and the fourth solenoid valve 6 is located on the fourth pipe 11 between the micro-mist humidification box 1 and the micro-mist humidification control cabinet 19. 4. The fifth solenoid valve 7 is located on the fifth pipe 15 between the micro-mist humidification box 1 and the micro-mist humidification control cabinet 19; the sixth solenoid valve 8 is located on the sixth pipe 16 between the micro-mist humidification box 1 and the micro-mist humidification control cabinet 19; the seventh solenoid valve 9 is located on the seventh pipe 17 between the micro-mist humidification box 1 and the micro-mist humidification control cabinet 19; and the eighth solenoid valve 10 is located on the eighth pipe 18 between the micro-mist humidification box 1 and the micro-mist humidification control cabinet 19.

[0027] Specifically, the first solenoid valve 3, the second solenoid valve 4, the third solenoid valve 5, the fourth solenoid valve 6, the fifth solenoid valve 7, the sixth solenoid valve 8, the seventh solenoid valve 9, and the eighth solenoid valve 10 each include a high-pressure corrosion-resistant direct-acting solenoid valve.

[0028] Furthermore, the micro-mist humidification control cabinet 19 employs a PLC control system or is connected to a central control computer to realize control functions. Those skilled in the art will understand that the above hardware selection is merely an example, and this utility model does not specifically limit the hardware model or installation location.

[0029] Furthermore, the combined air conditioning high-pressure micro-mist humidification control system also includes an air humidity sensor 20 located at the rear end of the air conditioning system and electrically connected to the micro-mist humidification control cabinet 19. Thus, the micro-mist humidification control cabinet 19 can, based on the feedback signal from the air humidity sensor 20, compare the current humidity with the set humidity value in real time, thereby triggering the corresponding solenoid valve to operate. In other words, the change in air humidity at the rear end of the air conditioning system serves as the condition for starting and stopping the micro-mist humidification system.

[0030] In one embodiment of this utility model, such as Figure 2 As shown, the working process of the combined air conditioning high-pressure micro-mist humidification control system is as follows:

[0031] During the operation of the air conditioning system, the micro-mist humidification control cabinet 19 collects the signal from the air humidity sensor 20 in real time and calculates the current air humidity based on the feedback signal;

[0032] The micro-mist humidification control cabinet 19 compares the current humidity with the target humidity value set by the system.

[0033] If the system is in automatic operation mode, when the current humidity is detected to be lower than the set value, the system will issue an alarm. The micro-mist humidification control cabinet 19 will calculate the required humidification amount and gradually increase the number of nozzles by activating different solenoid valves in sequence, while continuously monitoring the real-time humidity.

[0034] When the real-time humidity approaches the set value, the micro-mist humidification control cabinet 19 gradually reduces the number of nozzles, so that the humidity fluctuates smoothly within the target range.

[0035] If the system is in manual operation mode, when the humidity is lower than the set value, the system will alarm, and the control cabinet will open the corresponding solenoid valve to perform humidification operation according to the humidification amount command input by the operator.

[0036] When the difference between the real-time humidity and the set value is less than a certain threshold (e.g., 0.5%), it indicates that the adjustment is nearing completion. At this point, all nozzles can be gradually closed to stop humidification, thus avoiding frequent start-stop of the solenoid valve at the critical point and extending its service life.

[0037] In addition, if the micro-mist humidification control cabinet 19 is started during the humidification process but the humidity does not change for a long time (e.g., 300 seconds), the system should output a fault signal and notify maintenance personnel to handle it or switch to manual monitoring.

[0038] The accuracy of the micro-mist humidification adjustment of this utility model depends on the monitoring accuracy of the air humidity sensor 20 and the working status of each micro-mist nozzle 2. Therefore, before the system is put into operation, the air humidity sensor 20 needs to be calibrated, and the water output and atomization status of each micro-mist nozzle 2 need to be checked to ensure the accuracy of humidification control.

[0039] The combined air conditioning high-pressure micro-mist humidification control system provided in this embodiment optimizes the pipeline layout and nozzle connection method of the micro-mist humidification system, and combines the collaborative control strategy of multi-channel electric valves to achieve high-precision dynamic adjustment of humidification, thereby improving the micro-mist humidification adjustment accuracy. It can improve the control accuracy of the humidification system to ±1%, which is significantly better than the ±14.28% control accuracy under the existing control mode.

[0040] The embodiments of this disclosure have now been described in detail. To avoid obscuring the concept of this disclosure, some details known in the art have not been described.
