Description

Technical Field

[0001] This application relates to the field of air conditioning technology, specifically to a method and system for improving the humidity of a space, and in particular to a method and system for achieving long-distance, uniform, healthy and sterile humidification of a large space by combining negative ion technology with water spray technology. Background Technology

[0002] Maintaining appropriate indoor air humidity is crucial for human health, comfort, and even the protection of furniture and equipment. Excessively dry air can cause skin and respiratory discomfort, accelerate the spread of viruses, and may lead to problems such as cracking and static electricity in wooden furniture.

[0003] Currently, the mainstream humidification technologies on the market mainly include ultrasonic humidification technology, evaporative humidification technology, and high-pressure spray humidification technology.

[0004] Ultrasonic humidification technology uses the high-frequency vibration of piezoelectric ceramic transducers to break water into micron-sized fine particles and spray them into the air. It boasts advantages such as high humidification efficiency, low energy consumption, and low noise. However, ultrasonic humidification technology has the following drawbacks: 1. Due to the small size of the sprayed water mist particles and their limited initial kinetic energy, their diffusion ability is weak, causing them to easily settle around the humidifier, resulting in excessively high humidity in the vicinity while areas far from the device remain dry, making it difficult to achieve uniform humidification in large spaces; 2. If untreated tap water is used, minerals in the water will diffuse with the water mist, forming white dust that pollutes indoor air and furniture surfaces. While using purified water can avoid this problem, it increases operating costs; 3. If the water in the tank remains stagnant for a long time, bacteria, mold, and other microorganisms can easily grow and enter the air with the water mist, causing biological pollution and potentially inducing respiratory diseases such as "humidifier pneumonia."

[0005] Evaporative humidification technology humidifies by passing air through a moistened filter or by heating water to produce steam. Its advantages include lower water quality requirements and the absence of "white powder" residue from the emitted water vapor. However, it has the following drawbacks: 1. Slow humidification speed: The humidification rate is limited by the natural evaporation rate of the water or the heating power, and is generally slow, making it difficult to quickly increase the humidity in large spaces; 2. High energy consumption for hot evaporation; cold evaporation requires a fan to drive air circulation, which generates noise, and the limited airflow of the fan also leads to uneven humidification and the existence of dead zones; 3. The filter still needs to be cleaned or replaced regularly, otherwise it can become a breeding ground for microorganisms.

[0006] High-pressure spray humidification technology is mainly used in industrial or agricultural greenhouses. It uses a high-pressure pump to spray water from precision nozzles to form fine mist droplets. Although it has a large humidification capacity, it usually suffers from problems such as high noise, uneven droplet size distribution, short diffusion distance, and localized overhumidification. In addition, the system is complex and not suitable for quiet indoor environments.

[0007] In summary, the core challenge of existing indoor humidification technologies lies in the difficulty of simultaneously achieving the three goals of "uniform humidification in large spaces," "healthy and sterile environment," and "low energy consumption and quiet operation."

[0008] Therefore, there is an urgent need in this field for a new solution that can overcome the limitations of existing technologies and achieve rapid, uniform, safe, and efficient air humidification. Summary of the Invention

[0009] To overcome the shortcomings of the prior art, this application provides a uniform humidification method and system based on negative ion boosting spray, which does not rely on traditional passive evaporation or simple mechanical spraying, but uses physical methods to endow water mist particles with strong autonomous diffusion capabilities, and ensures hygiene and safety during the humidification process.

[0010] In a first aspect, this application provides a method for regulating ambient humidity, the method comprising the following steps: S1. Environmental parameter sensing: Monitor the relative humidity of different areas in the target space and obtain humidity distribution data of the target space; S2. Control Parameter Decision: Based on humidity distribution data and preset target humidity value, calculate the initial spray control parameters and negative ion generation control parameters; S3, Enabling Water Mist Generation: Water spray is generated according to spray control parameters, and negative ions are generated according to negative ion generation control parameters, so that the water spray and negative ions are mixed to form an empowering water mist with a negative charge; S4. Spatial Spraying and Adaptive Adjustment: The energized water mist is sprayed into the target space to regulate humidity, and the spray control parameters and / or negative ion generation control parameters are dynamically adjusted based on the real-time monitoring of the relative humidity of different areas of the target space. S5. Stop humidification: When the humidity distribution data of the target space reaches and stabilizes at the target humidity value, first stop generating water spray, and after a predetermined delay, stop generating negative ions.

[0011] In one alternative implementation, in step S1, acquiring the humidity distribution data of the target space specifically includes: monitoring the relative humidity values ​​of multiple points in the target space using a main humidity sensor and at least one remote humidity sensor, and generating a space humidity distribution map based on the location information and relative humidity values ​​of each point.

[0012] In one alternative implementation, in step S2, the spray control parameters and negative ion generation control parameters are calculated as follows: the spray control parameter is the spray flow rate Qw, which is positively correlated with the humidity difference ΔRH between the minimum relative humidity value RH_min and the target humidity value RH_target of the target space; the negative ion generation control parameter is the negative ion emission intensity I, which is positively correlated with the product of the spray flow rate Qw and the humidity difference ΔRH.

[0013] In one alternative implementation, step S3, prior to generating the water spray, includes a water pretreatment step: filtering and softening the supply water to remove dissolved minerals.

[0014] In one alternative implementation, the specific method for generating water spray in step S3 is as follows: using an ultrasonic atomizer to break water into droplets with a particle size between 1 and 10 micrometers; or using a high-pressure pump and a nozzle to atomize water into droplets with a particle size between 5 and 20 micrometers.

[0015] In one alternative implementation, the step S3 of "mixing water spray and negative ions" specifically includes: mixing water spray with airflow to form a mist-carrying airflow, and then mixing negative ions with the mist-carrying airflow to form an energized water mist.

[0016] In one alternative implementation, in step S3, the charge-to-mass ratio of the water mist particles that enable the water mist is 1.0 × 10⁻⁶. -4 C / kg up to 5.0×10 -4 C / kg.

[0017] In one alternative implementation, the "dynamic adjustment" in step S4 specifically includes: if the rate of increase of the relative humidity value in the remote monitoring area is lower than that in the near monitoring area, then the spray control parameters and / or the negative ion generation control parameters are increased.

[0018] Secondly, this application provides a space humidity control system for implementing the above-mentioned method for controlling space humidity.

[0019] Specifically, the space humidity control system includes a sensing module, a control module, a water system module, an ion system module, and a coupling jet module; The sensing module includes a main humidity sensor and at least one remote humidity sensor. The sensing module is used to monitor the relative humidity of different areas in the target space and obtain humidity distribution data of the target space. The control module includes a microprocessor. The control module is used to receive humidity distribution data from the sensor module, calculate the initial spray control parameters and negative ion generation control parameters based on the humidity distribution data and the preset target humidity value, and control the operation of the water system module and the ion system module. The water system module includes a water tank, a water pump, and an atomizer. The water system module receives spray control parameters from the control module, starts the water pump to transfer water from the water tank to the atomizer, and the atomizer produces water spray. The ion system module includes a negative ion generator. The ion system module receives negative ion generation control parameters from the control module and starts the negative ion generator to produce negative ions. The coupled spray module includes a mixing sprayer that mixes water spray and negative ions to form a negatively charged energized water mist, which is then sprayed into the target space for humidity regulation.

[0020] The technical solution provided by the aforementioned implementation method has at least the following beneficial effects: (1) The space humidity regulation method and system provided in this application combine water mist with negative ions to form energized water mist. Through the Coulomb repulsion between negative ions, the water mist particles repel each other, thereby obtaining continuous and driving diffusion power, solving the problem of "near-wet and far-dry" in traditional humidifiers, and realizing uniform humidity distribution in large spaces.

[0021] (2) By combining with negative ions, the diffusion distance of water mist is no longer determined solely by the initial kinetic energy. The electrostatic force provides an additional and lasting thrust to the water mist particles, which greatly increases the humidification radius.

[0022] (3) The negative ions in the water mist have a certain air purification ability. While humidifying the space environment, they can also effectively adsorb tiny dust and bacteria in the air, thus achieving a purification effect.

[0023] (4) The space humidity regulation method and system provided in this application can achieve long-distance diffusion of water mist without the need for a high-power fan. The overall power consumption is low and the operating noise is low, making it suitable for quiet environments such as bedrooms and studies.

[0024] (5) This application ensures the dryness and cleanliness of the water spray generation system by first stopping the water mist and then stopping the negative ions through an original maintenance procedure design. It also solves the hidden dangers of microbial growth and spread by utilizing the antibacterial effect of negative ions. Attached Figure Description

[0030] Combination Figure 1 In order to address the shortcomings of existing humidification methods and devices, this application provides a method for regulating spatial humidity, the method comprising the following steps: S1. Environmental parameter sensing: Monitor the relative humidity of different areas in the target space and obtain humidity distribution data of the target space; S2. Control Parameter Decision: Based on humidity distribution data and preset target humidity value, calculate the initial spray control parameters and negative ion generation control parameters; S3, Enabling Water Mist Generation: Water spray is generated according to spray control parameters, and negative ions are generated according to negative ion generation control parameters, so that the water spray and negative ions are mixed to form an empowering water mist with a negative charge; S4. Spatial Spraying and Adaptive Adjustment: The energized water mist is sprayed into the target space to regulate humidity, and the spray control parameters and / or negative ion generation control parameters are dynamically adjusted based on the real-time monitoring of the relative humidity of different areas of the target space. S5. Stop humidification: When the humidity distribution data of the target space reaches and stabilizes at the target humidity value, first stop generating water spray, and after a predetermined delay, stop generating negative ions.

[0031] In order to achieve multi-point monitoring, in step S1, the acquisition of humidity distribution data of the target space specifically includes: monitoring the relative humidity values ​​of multiple points in the target space through the main humidity sensor and at least one remote humidity sensor, and generating a space humidity distribution map based on the location information and relative humidity values ​​of each point.

[0032] The main humidity sensor is located near the spraying area of ​​the water mist. Without considering other humidity-generating factors, the relative humidity value of the spraying area of ​​the water mist is theoretically the maximum relative humidity value at each point.

[0033] The purpose of this step is to transform discrete, point-like relative humidity data into a digital model that reflects the continuous humidity distribution across the entire large space. This is the prerequisite and the "brain" for achieving precise, adaptive humidification. It avoids the problems of localized overhumidification or continued dryness in more distant areas caused by traditional humidifiers relying solely on a single sensor reading. In specific implementations, the number and location of remote humidity sensors can be set based on information such as the size and layout of the target space and key areas of interest. Specifically, the larger the target space, the more remote humidity sensors are needed to obtain more accurate humidity distribution data.

[0034] In one embodiment, the specific control steps and algorithm for generating a spatial humidity distribution map are as follows: Step S1.1, Data Acquisition and Coordinate Conversion: (1) Define the position of the main humidity sensor as the origin of the three-dimensional spatial coordinate system O (0,0,0); (2) When each remote humidity sensor is first configured on the network, its approximate position information relative to the main humidity sensor is input through the smart terminal program or the device panel, and spatial position attributes are assigned to each remote humidity sensor; for example, the coordinate point A (5,0,0) of remote humidity sensor No. 1 indicates that it is located 5 meters east of the main humidity sensor; the coordinate point B (0,3,0) of remote humidity sensor No. 2 indicates that it is located 3 meters north of the main humidity sensor. (3) Read the relative humidity (RH) readings of all sensors in a polling manner at a fixed sampling frequency to form a set of data points {(x_i,y_i,z_i),RH_i}, where i is the sensor number.

[0035] Step S1.2, Spatial interpolation calculation: The humidity value at locations where no sensors are set in the target space is estimated using a spatial interpolation algorithm.

[0036] In one embodiment, inverse distance weighting (IDW) is used for estimation.

[0037] The principle of the IDE algorithm is as follows: the humidity value RH_p of an unknown point P is obtained by weighted averaging of the humidity values ​​of known sensor points around it. The weight is a power function of the inverse of the distance from the unknown point P to each known sensor point i. The closer the sensor is to P, the greater its influence on RH_p.

[0038] The specific algorithm formula is as follows: RH_p=[∑(from i=1 to n)(w_i RH_i)] / [∑(from i=1 to n)w_i ] Among them, w_i=1 / (d_i p ); RH_p: Estimated humidity value at point p; n: The number of known sensors involved in the calculation; RH_i: The humidity reading of the i-th known sensor; d_i: The Euclidean distance from point P to the i-th sensor; p: Power parameter, usually p=2 (i.e., the square of the distance). The larger the p value, the greater the influence of nearby points, and the more localized the interpolation result; the smaller the p value, the more average the influence, and the smoother the result.

[0039] Step S1.3, Distribution Map Construction and Update: (1) Logically divide the entire target space into a three-dimensional grid (Voxel Grid), for example, each grid unit is 1m×1m×0.5m; (2) Using the IDE algorithm, calculate the estimated humidity value RH_p for each grid center point P in turn; (3) The humidity values ​​of all grid points together constitute a digitally processed spatial humidity distribution map, which is dynamically updated as data is collected periodically.

[0040] The following is an example to further illustrate the spatial humidity distribution algorithm.

[0041] like Figure 2 As shown, assuming a living room, a device host equipped with a water mist generator and a negative ion generator is used to implement the humidity regulation method provided in this application. The device host is equipped with a main humidity sensor. The device host is placed in a corner of the living room, and its position information is set to O(0,0,0). A remote humidity sensor is located in the opposite corner, and its position information is A(5,3,0).

[0042] At a certain moment, the relative humidity reading at point O(0,0,0) is 45%RH, and the reading at point A(5,3,0) is 38%RH. Suppose we need to estimate the relative humidity at point P(2,1,0), then: (a) Calculate the distance from P to O: d1 = sprt(2 2 +1 2 +0 2 )≈2.24m; (b) Calculate the distance from P to A: d² = sprt((5-2) 2 +(3-1) 2 +0 2 )≈3.61m; (c) If p=2, then the weight w1=1 / (2.24) 2 )≈0.20, w2=1 / (3.61) 2 )≈0.08; (d) Then RH_p≈(0.20) 45+0.08 38) / (0.20+0.08)=(9+3.04) / 0.28≈43%RH.

[0043] By calculating multiple location points, a humidity distribution model of the entire living room can be generated, and it may be discovered that the area where point A is located is a "dry zone".

[0044] To facilitate quantitative calculation, in step S2, the calculation methods for the spray control parameters and negative ion generation control parameters are as follows: the spray control parameter is the spray flow rate Qw, which is positively correlated with the humidity difference ΔRH between the minimum relative humidity value RH_min and the target humidity value RH_target in the target space; the negative ion generation control parameter is the negative ion emission intensity I, which is positively correlated with the product of the spray flow rate Qw and the humidity difference ΔRH.

[0045] The purpose of this algorithm is to transform the spatial humidity distribution map obtained in the previous step into specific execution instructions. It can calculate how much "water spray" needs to be generated and how strong its diffusion ability needs to be, in order to achieve the goal of efficient and uniform humidification.

[0046] In one embodiment, a method for calculating spray control parameters and negative ion generation control parameters is provided.

[0047] The specific control steps and algorithms are as follows: Step S2.1: Determine the key control variables (a) Extract the lowest humidity value RH_min and its location from the spatial humidity distribution map. RH_min represents the driest area in the target space that most needs humidification and is a key reference for humidity control.

[0048] (b) Obtain the target humidity value RH_target set by the user.

[0049] Step S2.2: Calculate the spray flow rate Q_w The spray flow rate is calculated using the following formula: Q_w=k2 (RH_target-RH_min)+b2 Parameter description: Q_w: Spray flow rate, in milliliters per minute (mL / min), which is the target value to be controlled; (RH_target-RH_min): The difference between the current humidity and the target humidity, i.e., the humidity difference ΔRH. The larger the difference, the greater the amount of humidification (i.e., the amount of water spray) required. k2: Proportional coefficient, with units of mL / min / %RH, which defines how much water is needed per unit humidity difference; the value of k2 can be determined through experimental calibration, and calibration factors include target space volume, space sealing, ambient temperature, etc. b2: Minimum starting flow rate, in mL / min. When the humidity difference ΔRH is very small, a very small spray volume is maintained for fine-tuning or compensating for natural evaporation. b2 can be set to 0.

[0050] For example: Given RH_target = 50%, RH_min = 40%, k2 = 1.5 mL / min / %RH, and b2 = 0.5 mL / min, then Q_w = 15 (50-40)+0.5=15.5 mL / min.

[0051] Step S2.3: Calculate the negative ion emission intensity I The emission intensity is calculated using the formula: I=k1 (RH_target-RH_min) Q_w+b1 Parameter description: I: Negative ion emission intensity, in units of "ions / second". (RH_target-RH_min): The difference between the current humidity and the target humidity, i.e., the humidity difference ΔRH; Q_w: Spray flow rate calculated in the previous step; k1: Proportionality coefficient, unit: ions·s -1 ·(mL·min -1 %RH -1 ) -1It defines the required ionic strength per unit of humidification intensity, and k1 is also calibrated experimentally to ensure the formation of an energized water mist with the optimal charge-to-mass ratio; b1: Minimum ion emission intensity, in ions / s, can be set to 0.

[0052] The formula for calculating emission intensity means that the required ion intensity is directly proportional to the overall load of the humidification task (humidity difference × water volume). This not only ensures that there are enough negative ions to charge the water mist, but also enables intelligent linkage and adjustment between the ion system and the water system, avoiding the problems of insufficient ions leading to short diffusion distance or excessive ions leading to wasted energy.

[0053] For example: Let k1 = 0.5 10 7 ions·s -1 / (mL·min -1 ·%RH), b1=0; Then I=0.5 10 7 (50-40) 15.5≈7.75 10 8 ions / s.

[0054] In order to achieve stable control of humidity in the target space, the "dynamic adjustment" in step S4 specifically includes: if the relative humidity value of the remote monitoring area increases at a lower rate than that of the near monitoring area, then the spray control parameters and / or negative ion generation control parameters are increased.

[0055] In this application, the spray control parameters and negative ion generation control parameters are controlled using closed-loop control. Data is collected periodically at set intervals, and the distribution map, RH_min, and output values ​​of Q_w and I are updated in real time.

[0056] As the humidity of the driest region RH_min gradually increases, the humidity difference ΔRH decreases. According to the steps and algorithm of this application, the spray flow rate and negative ion emission intensity gradually decrease until the set target humidity value RH_target is reached and tends to balance, thus achieving self-adaptation and energy saving.

[0057] In this application, in order to avoid the generation and deposition of mineral dust in the water, a water pretreatment step is included before generating water spray in step S3: filtering and softening the supply water to filter out dissolved minerals in the water.

[0058] In this application, the specific method for generating water spray in step S3 is as follows: using an ultrasonic atomizer to break water into droplets with a particle size between 1 and 10 micrometers; or using a high-pressure pump and a nozzle to atomize water into droplets with a particle size between 5 and 20 micrometers.

[0059] In this application, the step S3 of "mixing water spray and negative ions" specifically includes: mixing water spray with airflow to form a mist-carrying airflow, and then mixing negative ions with the mist-carrying airflow to form an energized water mist.

[0060] Specifically, a fan can be used to generate airflow to propel the water mist outward. The negative ion generation point is located on the path of the mist-carrying airflow. The mist-carrying airflow and negative ions mix to form an outward-moving energized water mist.

[0061] In one embodiment, a hybrid jetting device can be used to mix and spray the mist-carrying airflow and negative ions, thereby achieving efficient mixing of water spray and negative ions and enabling the sprayed energized water mist droplets to achieve a smaller particle size.

[0062] Combination Figure 3 The mixing sprayer employs a Venturi sprayer. This Venturi sprayer 10 includes an inlet 11, a mixing chamber 12, a constriction 13, and a diffuser 14. The mist-carrying airflow 20, propelled by wind, enters the mixing chamber 12 through the inlet 11. The mixing chamber 12 has an opening, through which negative ions 30 enter and mix with the mist-carrying airflow 20 before entering the constriction 13. At the constriction 13, the negative ions 30 mix with the mist-carrying airflow 20 to form an energized water mist 40. The energized water mist 40 diffuses in the diffuser 14 before being discharged. The diffuser 14 further reduces the droplet size of the energized water mist 40, allowing it to achieve a greater diffusion distance under the driving force of the airflow.

[0063] To achieve a good diffusion effect, in step S3, the charge-to-mass ratio of the water mist particles is 1.0 × 10⁻⁶. - 4 C / kg up to 5.0×10 -4 C / kg.

[0064] In this application, when the humidity distribution data of the target space reaches and stabilizes at the target humidity value, water spray generation is first stopped, and negative ion generation is stopped after a predetermined delay. By delaying the cessation of negative ion generation, more negative ions can be imparted to the spray system, achieving a sterilization effect and solving the problem of microbial growth present in conventional spray humidification systems.

[0065] This application also provides an embodiment of a space humidity control system.

[0066] Combination Figure 4 As shown, specifically, the space humidity control system includes a sensing module 100, a control module 200, a water system module 300, an ion system module 400, and a coupling jet module 500.

[0067] Specifically, the sensing module includes a main humidity sensor and at least one remote humidity sensor. The sensing module is used to monitor the relative humidity of different areas in the target space and obtain humidity distribution data of the target space.

[0068] The sensing module can transmit signals to the control module via a data cable or via a wireless communication module.

[0069] The control module includes a microprocessor. The control module receives humidity distribution data from the sensor module, calculates initial spray control parameters and negative ion generation control parameters based on the humidity distribution data and the preset target humidity value, and controls the operation of the water system module and the ion system module.

[0070] The microprocessor can be a conventional microprocessor chip to perform data processing and calculations. Additionally, the control module can be equipped with a memory to facilitate data storage and retrieval.

[0071] The water system module includes a water tank, a water pump, and an atomizer. The water system module receives spray control parameters from the control module, starts the water pump to transfer water from the water tank to the atomizer, and the atomizer produces water spray.

[0072] The water system module is also equipped with a fan that can output airflow to discharge water spray outwards, providing the initial driving force for the diffusion of water spray.

[0073] The ion system module includes a negative ion generator. The ion system module receives negative ion generation control parameters from the control module and starts the negative ion generator to produce negative ions.

[0074] The coupled spray module includes a mixing sprayer that mixes water spray and negative ions to form a negatively charged energized water mist, which is then sprayed into the target space for humidity regulation.

[0075] In one embodiment, the control module, water system module, ion system module and coupling jet module are integrated into a humidification device body. The main humidity sensor of the sensing module is set on the humidification device body, and the remote humidity sensor is installed according to the actual situation of the target space and the humidification requirements.

[0076] Comparative Test: A comparative experiment was conducted to adjust the humidity of the target space and monitor the relative humidity and negative ion levels at multiple test points. The initial relative humidity of the target space was 25%.

[0077] Specifically, in the test example, the space humidity control system of this application was used to control the humidity of the target space at a spray flow rate of 16 mL / min and 8 10 8Humidify for 60 minutes with negative ion emission intensity of ions / s.

[0078] In the comparative example, the space humidity control system of this application was used, the ion system module was stopped, and humidification was carried out for 60 minutes using the same spray flow rate as the test example.

[0079] Based on the locations shown in Table 1, remote humidity sensors were installed and negative ion levels were monitored simultaneously. The results are shown in Table 1. Table 1. Results of multi-point monitoring According to the results in Table 1, it can be seen that the humidification distance of the test example using the humidity control method of this application is greater than that of the comparative example, and its far-end diffusion ability is also stronger than that of the comparative example.
