At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0021] Please refer to Figure 1 , Figure 1 This is a system diagram of a humidification control system using a heating coil in an air conditioning unit in some embodiments of the present application. The humidification control system using a heating coil in an air conditioning unit includes: A surface cooler assembly (1), a lift pump assembly (2), a water level sensor (3), a humidification water inlet assembly (4), a humidification water storage box (5) and a humidification water replenishment box (6); The surface cooler assembly (1) comprises a surface cooler (11), a hot water inlet pipe (12) and a hot water return pipe (13), and is used for humidifying the purified water by circulating the hot water supply and evaporating the water; The water level sensor (3) is used to monitor the water level data of the pure water in the humidification water storage box in real time; The humidification water inlet component (4) is used to replenish pure water into the humidification water replenishment box; The humidification water storage box (5) is used to store pure water; The humidification and water replenishment box (6) is used to store the pure water replenished by the humidification and water replenishment box.

[0022] It should be noted that the humidification water storage box in the system is used to store condensed pure water or pure water added from the outside. The pure water level data in the humidification water storage box is monitored by a water level sensor, and water is replenished, humidified or drained according to the water level data. When humidification is needed, the humidification lift pump in the lift pump assembly is used to lift the pure water into the humidification water replenishment box and pour it into the surface cooler. The hot circulating water in the surface cooler is evaporated for air humidification. When the water level data exceeds the preset value, the pure water is prevented from overflowing, and the condensation lift pump in the lift pump assembly is used to discharge the excess pure water, thereby realizing multi-pump coordination, precise water level control and thermal energy integration.

[0023] According to an embodiment of the present invention, the humidification control system using a heating coil in an air-conditioning unit, the lift pump assembly (2) comprises: The humidification lift pump assembly (21) comprises a humidification lift pump (211), a humidification lift float valve (212) and a humidification lift water outlet pipe (213), and is used to control the humidification lift float valve according to a humidification instruction to lift the purified water in the humidification water storage box into the humidification water supply box; The condensation lift pump assembly (22) comprises a condensation lift pump (221), a condensation float valve (222) and a condensation water outlet pipe (223), and is used to control the condensation float valve according to the water level sensor to discharge the pure water in the humidification water storage box out of the humidification water storage box.

[0024] It should be noted that when the system receives the humidification command, it controls the humidification lift float valve to open the humidification lift pump, and lifts the pure water in the humidification water storage box to the humidification water supply box for air humidification. When it is monitored that the water level reaches the set value, the condensation float valve is controlled to open the condensation lift pump to discharge the pure water in the humidification water storage box to prevent the pure water from overflowing.

[0025] According to an embodiment of the present invention, the humidification control system using a heating coil in an air-conditioning unit, the humidification water inlet component (4) comprises: The humidification water inlet float valve (41), the humidification water inlet control valve (42) and the humidification water inlet pipe (43) are used to control the humidification water inlet control valve according to the water level sensor to replenish pure water into the humidification water storage box.

[0026] It should be noted that when the water level of the pure water in the humidification water storage box is monitored to be lower than the set value, the humidification water inlet control valve is controlled to open and pure water is added to the humidification water storage box to prevent the water level in the humidification water storage box from being too low and affecting the implementation of humidification.

[0027] The present invention also discloses a humidification control method using a heating coil in an air conditioning unit, please refer to Figure 2 , Figure 2 This is a flow chart of a method for controlling humidification using a heating coil in an air conditioning unit in some embodiments of the present application. This method for controlling humidification using a heating coil in an air conditioning unit is used in a terminal device, such as a computer or mobile phone terminal. This method for controlling humidification using a heating coil in an air conditioning unit includes the following steps: S21, obtaining first relative humidity at multiple preset locations indoors, and performing analysis and processing to obtain a first humidity state indoors, including suitable humidity, insufficient humidity, or high humidity; S22: If the humidity is insufficient, obtain the real-time water level data in the humidification water storage box, and control the humidification boost pump to execute the humidification instruction according to the real-time water level data; S23, obtaining a second relative humidity at a plurality of preset locations in the room after the first preset time period, and performing analysis and processing to obtain a second humidity state in the room, including suitable humidity or insufficient humidity; S24: If the humidity is appropriate, obtain a third relative humidity at a preset location in the room after a second preset time period, and process the humidity in combination with the second relative humidity to obtain a humidification effect.

[0028] It should be noted that humidification is implemented according to the actual humidity conditions in the room, and the first relative humidity of multiple positions is weighted to determine the first humidity state in the room. If the humidity is appropriate or high, humidification is not implemented. If the humidity is insufficient, the water level in the humidification water storage box is further determined, and humidification is implemented. After humidification is performed for a period of time, the second humidity state in the room is monitored again, and the effectiveness of the humidification treatment is determined. The humidification implementation is controlled according to the humidification effectiveness.

[0029] Please refer to Figure 3 , Figure 3This is a flow chart of obtaining a first indoor humidity state for a method for controlling humidification using a heating coil in an air conditioning unit in some embodiments of the present application. According to an embodiment of the present invention, obtaining first relative humidity at multiple preset locations indoors and analyzing and processing the obtained first indoor humidity state, including suitable humidity, insufficient humidity, or high humidity, includes: S31, obtaining first relative humidity at multiple preset locations indoors; S32. Query a mapping table of preset positions and weight values according to the preset position to obtain a corresponding weight value; S33, performing weighted averaging processing on the first relative humidity and the corresponding weight value to obtain a first indoor relative humidity average; S34, comparing the first relative humidity mean with a first preset humidity threshold and a second preset humidity threshold respectively; S35. Obtaining a first indoor humidity state according to a range within which the first relative humidity mean falls, including suitable humidity, insufficient humidity, or high humidity; S36: If the humidity is appropriate, monitor the first relative humidity in real time; S37: If the humidity is insufficient, execute the humidification instruction; S38: If the humidity is high, output a warning response.

[0030] It should be noted that in order to determine the actual humidity in the room, humidity sensors are arranged at multiple preset positions to collect the first relative humidity in real time. The preset position and weight value mapping table are queried in combination with the position of the sensor to obtain the corresponding weight value, wherein the preset position and weight value mapping table is pre-set and can be dynamically adjusted. After weighted averaging processing, the first relative humidity average in the room is obtained. If it is less than the first preset humidity threshold, it is determined that the humidity is insufficient, and the humidification instruction is executed. If it is greater than or equal to the first preset humidity threshold and less than the second preset humidity threshold, it is determined that the humidity is appropriate, and the first relative humidity continues to be monitored in real time. If it is greater than or equal to the second preset humidity threshold, it is determined that the humidity is high, and an early warning response is output, wherein the first preset humidity threshold is less than the second preset humidity threshold.

[0031] According to an embodiment of the present invention, if the humidity is insufficient, real-time water level data in the humidification water storage box is obtained, and the humidification boost pump is controlled to execute the humidification instruction according to the real-time water level data, including: If the humidity is insufficient, obtain the real-time water level data in the humidification water storage box; Comparing the real-time water level data with the preset humidification water level data; If it is less than the preset humidification water level data, the humidification water inlet control valve is controlled to execute the water replenishment instruction; If it is greater than or equal to the preset humidification water level data, the humidification boost pump is controlled to execute the humidification instruction.

[0032] It should be noted that in order to better execute the humidification instruction, it is necessary to determine whether the water level in the humidification water storage box meets the requirements, and compare the real-time water level data in the humidification water storage box with the preset humidification water level data. If it is greater than or equal to, it means that there is sufficient water storage, and the humidification lift pump is directly turned on to lift the pure water into the humidification water replenishment box to execute the humidification instruction. If it is less than the preset humidification water level data, it means that there is insufficient water in the water storage box. First, add pure water through the humidification water inlet control valve, and then execute the humidification instruction after reaching the water level.

[0033] Please refer to Figure 4 , Figure 4 This is a flow chart of obtaining a second indoor humidity state for a method for controlling humidification using a heating coil in an air conditioning unit in some embodiments of the present application. According to embodiments of the present invention, obtaining a second relative humidity at multiple preset locations in the room after a first preset time period and analyzing and processing the obtained second indoor humidity state, including whether the humidity is appropriate or insufficient, includes: S41, obtaining second relative humidity at multiple preset locations in the room after a first preset time period; S42, performing weighted averaging processing based on the second relative humidity and the corresponding weight value to obtain a second relative humidity mean value in the room; S43: Compare the second relative humidity average with a first preset humidity threshold to obtain a second indoor humidity state; S44: If the humidity is less than the first preset humidity threshold, it is determined that the humidity is insufficient, and the humidification instruction is continuously executed; S45: If the humidity is greater than or equal to the first preset humidity threshold, it is determined that the humidity is appropriate.

[0034] It should be noted that after executing the humidification instruction, it is necessary to monitor the real-time humidity status to prevent the humidity from being too high. The same as monitoring and obtaining the first relative humidity, the second relative humidity of multiple preset positions in the room after the first preset time period is obtained. The first preset time period, such as 10 minutes after the humidification is executed, is weightedly averaged to obtain the second relative humidity average in the room. If it is less than the first preset humidity threshold, it means that the humidity has not reached the appropriate state after humidification, and the humidification instruction needs to be continuously executed. If it is greater than or equal to the first preset humidity threshold, it means that the humidification has met the requirements, and the humidity is determined to be appropriate.

[0035] According to an embodiment of the present invention, if the humidity is appropriate, obtaining a third relative humidity at a preset location indoors after a second preset time period, and processing the third relative humidity in combination with the second relative humidity to obtain a humidification effect includes: If the humidity is appropriate, obtaining a third relative humidity at the preset location indoors after the second preset time period; Performing weighted averaging processing according to the third relative humidity combined with the corresponding weight value to obtain a third indoor relative humidity average; Comparing the third relative humidity average with the second relative humidity average to obtain a humidity increase rate; Comparing the humidity increase rate with a preset humidity increase rate threshold; If it is less than the preset humidity increase rate threshold, the humidification command will continue to be executed; If it is greater than or equal to the preset humidity increase rate threshold, obtaining the first sampling number that is continuously greater than or equal to the preset humidity increase rate threshold; Comparing the first sampling times with a preset times threshold; If the number of times is less than the preset threshold, it is determined that the humidification effect is insufficient and the humidification instruction is continued; If the number is greater than or equal to the preset threshold, it is determined that the humidification is effective, and the humidification boost pump is controlled to stop the humidification instruction.

[0036] It should be noted that in order to prevent humidification from being stopped as soon as the humidity is reached, and from being turned on again when the humidity is insufficient, frequent starting and stopping will affect the user experience and reduce the service life of the equipment. After the indoor humidity is determined to be appropriate, the third relative humidity of the indoor preset position is calculated after a second preset time period. In the second preset time period, if the indoor humidity is determined to be appropriate 3 minutes later, the weighted average is processed to obtain the third relative humidity average of the room, and compared with the second relative humidity average to obtain the humidity increase rate. For example, the second relative humidity average is 0.4, and the third relative humidity average is 0.43, then (0.43-0.4) / 0.4=0.075, which is the humidity If the humidity increase rate is a negative value, that is, the third relative humidity mean is less than the second relative humidity mean, it is directly recorded as 0. Then, the humidity increase rate is compared with the preset humidity increase rate threshold. If it is less than, it means that the humidification effect is not satisfactory and humidification needs to be continued. If it is greater than or equal to, continue to monitor the first sampling times that are continuously greater than or equal to the preset humidity increase rate threshold, and compare it with the preset number threshold. For example, if the first sampling times that are continuously greater than or equal to the preset humidity increase rate threshold are 3 times, and the preset number threshold is 2 times, it is determined that humidification is effective, and the humidification boost pump is controlled to stop the humidification instruction. Otherwise, the humidification process continues.

[0037] According to an embodiment of the present invention, the further embodiment includes: Comparing the real-time water level data with the preset drainage water level data; If it is greater than or equal to the preset drainage water level data, the condensing lift pump is controlled to execute the drainage instruction.

[0038] It should be noted that in order to prevent excessive water storage in the humidification water storage box and the overflow of pure water, the real-time water level data monitored in real time is compared with the preset drainage water level data. If it is less than, it means that the water storage is appropriate and no treatment is required. If it is greater than or equal to the preset drainage water level data, it means that there is too much water storage. The pure water is discharged from the water storage box through the condensation lift pump to achieve multi-pump collaborative processing.

[0039] According to an embodiment of the present invention, if the number of times is less than a preset threshold, it is determined that the humidification effect is insufficient, and the humidification instruction is continuously executed, and then the following steps are further included: Obtaining a second sampling number that is continuously less than a preset humidity increase rate threshold; If the second sampling number is greater than a preset number threshold, the hot water supply temperature in the surface cooler is increased according to a preset gradient.

[0040] It should be noted that in order to make the indoor humidity reach an appropriate level as soon as possible, when the second sampling number of the humidity increase rate continuously less than the preset humidity increase rate threshold is greater than the preset number threshold, it means that the current humidification execution effect is insufficient, and the hot circulating water in the surface cooler is increased according to the preset gradient, such as increasing it by 5°C each time. By increasing the hot circulating water temperature, the evaporation effect is improved, thereby increasing the air supply humidification effect.

[0041] It is worth mentioning that according to an embodiment of the present invention, the present invention further includes: Get the storage time of pure water in the humidification water storage box; Comparing the water storage time with a preset water storage time threshold; If it is greater than the preset water storage time threshold, the condensation lift pump is controlled to discharge the pure water from the humidification water storage box.

[0042] It should be noted that if the pure water in the humidification water storage box is stored for a long time, bacteria will grow. If air humidification is performed again, the bacteria will be transmitted into the room, increasing health risks. Therefore, a threshold comparison is performed based on the water storage time. Once it is determined that the water storage exceeds the threshold, the pure water will be discharged from the humidification water storage box and replaced with new pure water.

[0043] It is worth mentioning that according to an embodiment of the present invention, the present invention further includes: Obtain the pH value, total bacteria count and iron bacteria content of the pure water in the humidification water storage box at a preset time point; Comparing the pH value, total bacteria count, and iron bacteria content with a preset pH nominal value, a preset bacteria allowable amount, and a preset iron bacteria allowable content to obtain a pH deviation rate, a bacteria exceeding standard rate, and an iron bacteria exceeding standard rate; The pH deviation rate, the bacteria exceeding the standard rate and the iron bacteria exceeding the standard rate are weighted and summed to obtain water quality evaluation data; Comparing the water quality assessment data with a preset water quality assessment threshold; If it is greater than or equal to the preset water quality assessment threshold, the actual water storage time is determined according to the preset time point; The preset water storage time limit threshold is adjusted according to the actual water storage time.

[0044] It should be noted that in order to determine the discharge cycle of pure water in the humidification water storage box, water quality tests are carried out regularly to obtain the pH deviation rate, bacteria exceedance rate and iron bacteria exceedance rate, among which the pH deviation rate refers to the absolute value of the difference between the pH value and the preset pH nominal value and the ratio of the preset pH nominal value, the bacteria exceedance rate refers to the total number of bacteria minus the preset bacteria allowable amount and the ratio of the preset bacteria allowable amount, the iron bacteria exceedance rate refers to the iron bacteria content minus the preset iron bacteria allowable content and the ratio of the preset iron bacteria allowable content. If the bacteria exceedance rate and the iron bacteria exceedance rate are negative, they are recorded as 0. When the water quality exceeds the standard, the actual water storage time, that is, the storage time of the pure water in the humidification water storage box, is determined according to the preset time point for water quality testing, and then the preset water storage time limit threshold is adjusted to avoid the discharge cycle being too long, resulting in the risk of bacteria breeding, or the discharge cycle being too short, resulting in waste of water resources.

[0045] The present invention discloses a control system and method for humidification using a heating coil in an air-conditioning unit. The control system and method evaluate a first humidity state by analyzing a first relative humidity, implement multi-pump coordination and multi-stage water level control, utilize pure water for circulating humidification, reduce energy loss, and do not require additional space, thereby achieving precise automated control of humidification using a heating coil.
