Abstract
Description
Technical Field
[0001] This invention relates to the field of air conditioning technology, and in particular to an air handling equipment, its control method and apparatus, and a storage medium. Background Technology
[0002] Most existing air conditioners only offer a few mechanical air delivery modes, such as directional airflow and oscillating airflow. The air outlets and impeller positions are fixed, and the cross-sectional area of the airflow is relatively small, resulting in mostly near-linear unidirectional airflow. This mechanical air delivery terminal design lacks theoretical support regarding the impact of airflow on human thermal comfort, resulting in poor air exchange cooling effect and blowing sensation, making it difficult to meet users' requirements for environmental comfort.
[0003] To address this, related technologies have proposed solutions to change the wind feel by actively adjusting the wind field distribution, which can be categorized as: 1) motor control method; 2) air guide plate control method; 3) turbulence device; 4) air dispersion structure; and 5) microporous wind deflector. However, the aforementioned related technical solutions have the following technical defects:
[0004] (1) The motor control method has excessively high requirements for motor performance, generates a lot of noise, and the motor and fan are easily damaged, resulting in a significant reduction in lifespan and product reliability.
[0005] (2) The wind deflector control method also requires a high-performance DC brushless motor to quickly respond to the wind speed sample signal of the natural wind and drive the wind deflector to rotate, which is costly; the wind deflector angle changes rapidly and generates a lot of noise; and it also reduces the lifespan of the motor and the wind deflector.
[0006] (3) The turbulence device needs to be installed inside the air conditioner outlet, which causes a serious reduction in air volume;
[0007] (4) When the blades in the air-diffusing structure rotate, the rotation speed is low, making it difficult to effectively adjust the wind feel;
[0008] (5) Microporous wind deflectors can only soften the airflow and are difficult to achieve a variety of wind sensations. Summary of the Invention

[0050] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0051] The air handling equipment, control method and apparatus, and storage medium of the present invention are described below with reference to the accompanying drawings and specific embodiments.
[0052] It should be noted that the air outlet of the air handling device in this embodiment of the invention is provided with an air guiding component. The air guiding component includes at least two air guiding groups, and each air guiding group is located in a different area along the length of the air outlet. Each air guiding group includes at least one (i.e., one or more spaced-apart) air guiding vanes. The air guiding component also includes a driving device, which includes a resonant actuator. The resonant actuator can drive the air guiding vanes to resonate to achieve turbulence. That is, the resonant actuator has the ability to drive the air guiding vanes to resonate. When the air guiding vanes resonate, turbulence can be achieved, thereby improving the airflow feel. Adjacent air guiding groups can be spaced by a preset distance (for example, the distance between adjacent air guiding vanes in adjacent air guiding groups is used to calculate the interval). This preset distance can be greater than or equal to the distance between two adjacent air guiding vanes in the same air guiding group.
[0053] Understandably, "resonance," also known as "resonance," occurs when the frequency of the driving force equals the system's natural frequency, resulting in the maximum amplitude of forced vibration. This phenomenon is called resonance. In an oscillating system under periodic external forces, the amplitude increases dramatically when the frequency of the external force is the same as or very close to the system's natural oscillation frequency. The frequency at which resonance occurs is called the "resonant frequency." Furthermore, "natural frequency," also called "natural frequency," refers to the frequency of free vibration. When an object vibrates freely, its displacement changes with time according to a sine or cosine law. The frequency of vibration is independent of initial conditions and depends only on the system's inherent characteristics (such as mass, shape, and material). This is called the natural frequency, and its corresponding period is called the natural period. The natural frequency is unrelated to external excitation; it is an inherent property of the structure. Regardless of whether external excitation is applied to the structure, its natural frequency exists. However, when external excitation occurs, the structure vibrates according to its natural frequency. In addition, "free vibration" refers to the vibration that occurs in a mechanical system after the excitation or constraint is removed. The vibration is maintained only by its elastic restoring force. When damping is applied, the vibration gradually decays. The frequency of free vibration is determined only by the physical properties of the system itself and is called the natural frequency of the system.
[0054] In simple terms, when the excitation frequency of the resonant actuator is the same as or close to the natural frequency of the air guide vane, the resonance effect is utilized. The vibration generated by the air guide vane is called resonance, and the amplitude of the air guide vane will increase sharply. Thus, the air guide vane can effectively turbulent the airflow and improve the airflow feel.
[0055] For example, such as Figure 1 As shown, when the resonant actuator is a piezoelectric material component, an alternating voltage is applied in the polarization direction of the piezoelectric material component. At this time, the piezoelectric material component will move in a certain direction (e.g., Figure 1 Periodic mechanical deformation occurs in the direction of vibration (as shown). Resonance (or synchrotron resonance) only occurs when the excitation frequency of the piezoelectric material is equal to or close to the natural frequency of the air guide plate. At this time, the air guide plate (i.e., Figure 1 The amplitude of the vibrating plate shown will increase sharply, so that the air guide plate can effectively turbulent the airflow and improve the airflow feel.
[0056] Optionally, in some embodiments, the resonant frequency of the resonant actuator driving the air guide vane to resonate is greater than or equal to 1Hz. Therefore, the air guide vane can achieve a better turbulence effect, improving the airflow feel. However, the DC brushless motors and stepper motors used in general air conditioners cannot drive the air guide vane to resonate at a frequency greater than 1Hz, and the air guide vane cannot effectively turbulent the airflow to improve the airflow feel.
[0057] It should be noted that there are many ways for a resonant actuator to drive the air guide vane to resonate. For example, a resonant actuator can include an actuator that uses at least one of the following driving forces—electric, magnetic, mechanical, or temperature fields—to achieve reciprocating motion, thus enabling flexible design. For instance, a resonant actuator can include a piezoelectric actuator, employing the inverse piezoelectric effect. The resonant actuator is a piezoelectric sheet, such as a piezoelectric ceramic, which utilizes the inverse piezoelectric effect to reciprocate and deform, driving the air guide vane to resonate and achieve the purpose of turbulence. The piezoelectric sheet is a sheet formed of piezoelectric material, such as a piezoelectric film. A piezoelectric film is a flexible, lightweight, and highly tough plastic film that can be made into objects of various thicknesses and large areas. It belongs to the category of piezoelectric materials and can be driven by alternating current to produce the inverse piezoelectric effect, thereby driving the air guide vane to resonate.
[0058] However, the present invention is not limited thereto. The resonant actuator can also drive the air guide vane to resonate in other ways, as illustrated below, but the present invention is not limited thereto.
[0059] For example, resonant actuators include electrostrictive actuators, which drive the air guide vanes to resonate through the electrostrictive effect.
[0060] Specifically, the electrostrictive effect refers to the phenomenon of elastic deformation of a dielectric material in an electric field. This phenomenon can be explained as follows: when a dielectric material is placed in an electric field, its molecules become polarized, with the positive pole of one molecule connecting to the negative pole of another molecule along the direction of the electric field. Due to the mutual attraction between the positive and negative poles, the entire dielectric material contracts in this direction until the internal elastic force and electro-attraction are balanced. In short, electrostrictive materials can be connected to air guide vanes, and alternating current can be used to drive the deformation of the electrostrictive material, thereby causing the air guide vanes to resonate.
[0061] Furthermore, it should be noted that the difference between electrostriction and the inverse piezoelectric effect lies in the following: the inverse piezoelectric effect is a linear response effect with a first-order term, and can only occur in solid dielectrics without a center of symmetry. The piezoelectric constant is a third-order tensor; the physical property parameters describing the electrostriction effect in anisotropic dielectrics are fourth-order tensors. In non-piezoelectric dielectrics, only the electrostriction effect occurs; in piezoelectric materials, both the piezoelectric and electrostriction effects occur simultaneously. Generally, the strain caused by the electrostriction effect is several orders of magnitude smaller than that caused by the inverse piezoelectric effect in piezoelectric materials.
[0062] For example, resonant actuators include magnetostrictive actuators, which drive the air guide vanes to resonate through the magnetostrictive effect.
[0063] Specifically, magnetostriction refers to the phenomenon where an object, when magnetized in a magnetic field, elongates or shortens in the direction of magnetization. Ferromagnetic materials exhibit significant dimensional changes when the current through a coil changes or the distance from the magnet is altered; these are commonly referred to as ferrostrictive materials. Materials with much larger dimensional changes than current magnetostrictive materials such as ferrites, and which also generate greater energy, are called supermagnetostrictive materials.
[0064] Because magnetostrictive materials change length under the influence of a magnetic field, they can undergo displacement and do work, or they can repeatedly stretch and shorten under the influence of an alternating magnetic field, thus generating vibration. This material can convert electromagnetic energy (or electromagnetic information) into mechanical energy. In short, magnetostrictive materials can be connected to air guide vanes, and the deformation of the magnetostrictive material can be driven by an alternating magnetic field, thereby causing the air guide vanes to resonate.
[0065] For example, resonant actuators include shape memory alloy actuators, which drive the air guide vanes to resonate through the deformation of the shape memory alloy.
[0066] Specifically, shape memory alloys (SMA) can undergo a martensitic phase transformation under external fields (temperature, stress, magnetic fields, etc.), exhibiting shape memory and superelasticity. They can output force and displacement, making them advanced intelligent materials integrating temperature sensing and intelligent actuation. They possess unique shape memory effects and phase transformation pseudoelasticity. Shape memory alloys have three characteristics: large deformation; high degree of freedom in displacement direction; and rapid displacement. Therefore, they feature large displacement, high power-to-weight ratio, rapid displacement, and free direction. In short, shape memory alloys can be connected to air guide vanes, and the temperature field can be changed through heating or cooling to drive the air guide vanes to resonate.
[0067] For example, resonant actuators include electrorheological fluid actuators, which drive the air guide vanes to resonate by electro-induced electrorheological fluid deformation.
[0068] Specifically, an electrorheological fluid (ERF) is a smart material whose viscosity changes with the strength of an applied electric field. Without an electric field, an ERF flows freely like a normal liquid, essentially a Newtonian fluid. When the applied electric field strength reaches a certain value, the properties of the ERF change significantly: the viscosity increases and it gradually loses its fluidity, its shear resistance increases, and it rapidly transforms from a liquid to a near-solid state. After the electric field is removed, it quickly returns to a liquid state. This state change can occur in just milliseconds, and this transformation is completely reversible. In short, an ERF can be connected to an air guide vane, and the vane can be driven to resonate by an alternating electric field.
[0069] For example, resonant actuators include servo actuators. A servo actuator can be a hydraulic actuator that converts hydraulic energy from a hydraulic source into mechanical energy. It can also be servo-controlled via a built-in displacement sensor or limit switch, as needed. It executes commands from the main controller to control the load's speed, direction, displacement, and force, while simultaneously feeding back signals to the main controller. It features high output force, accurate positioning, and small size. In short, a servo actuator can be connected to a guide vane to drive it to resonate.
[0070] It is understandable that the vibration direction of the air guide vanes can be adjusted by changing their installation direction at the air outlet, thereby creating turbulence in different directions. The control method in this embodiment, by controlling each air guide group to operate in the same or different turbulence modes, enables the air handling equipment to produce different airflow sensations, improving the user experience. Furthermore, when there are many people in the space where the air handling equipment is located, it can provide different airflow sensations to different users, providing more targeted air conditioning.
[0071] Figure 2 This is a schematic flowchart of a control method for an air handling device according to an embodiment of the present invention.
[0072] like Figure 2 As shown, the control method for the air handling equipment provided in this embodiment includes the following steps:
[0073] S10: Obtain the number of users in the space where the air handling unit is located.
[0074] Specifically, the air handling unit in this embodiment can accurately detect the presence of people in the space by using sensors to obtain the number of users in the space where the air handling unit is located. For example, the air handling unit is equipped with an infrared sensor. The human infrared sensor can emit infrared rays and receive infrared signals reflected back from the human body. The signal processing circuit processes these signals into high and low level digital signals and transmits them to the air conditioning control unit, thereby accurately detecting the number of users in the space where the air handling unit is located. In order to avoid false alarms, the human infrared sensor probe is driven and fixed by a gimbal motor. By configuring a cyclically rotating monitoring angle, it actively detects and collects infrared waves emitted by the human body in the enclosed environment to obtain the number of users in the space where the air handling unit is located.
[0075] It should be noted that the embodiments of the present invention merely illustrate one method of obtaining the number of users in the space where the air handling equipment is located using an infrared sensing device. Cameras, ultrasonic sensors, or other devices can also be used instead of infrared sensors. For example, by utilizing the characteristic of ultrasonic waves reflecting off objects, the number of users and their direction in the space where the air handling equipment is located can be detected. This method of obtaining the number of users is not limited to the method used in this application. In other embodiments of the present invention, the number of users can also be determined based on user input.
[0076] S20, when the number of users is greater than or equal to the preset number threshold, controls each air guide group to work in the same or different turbulence modes.
[0077] Specifically, the air guiding component in this embodiment includes multiple air guiding groups, each of which can be controlled independently. It is assumed that there are M air guiding groups at the air outlet of the air handling equipment, where M ≥ 2. This means that at least two air guiding groups are provided at the air outlet of the air handling equipment. When at least two of the M air guiding groups operate with different vibration frequencies and amplitudes, at least two different turbulent airflow modes can be achieved in the corresponding areas, thus achieving the purpose of zoned airflow.
[0078] Based on the number of users in the space where the air handling unit is located, the system controls the air handling unit to activate the zoned air supply mode and determines the air supply mode of the air guide groups. Specifically, the number of users in the space where the air handling unit is located can be compared with a preset number threshold. Taking a preset number threshold of 2 as an example, if the number of users in the space is less than the preset number threshold of 2, the zoned air supply mode is not activated because there is only one user or no user at this time, so there is no need for zoned air supply, and only air supply needs to be provided to that user. Therefore, all air guide groups can operate with the same turbulence mode. If the number of users in the space is greater than or equal to the preset number threshold of 2, then all air guide groups can be controlled to operate with the same turbulence mode, or each air guide group can be controlled to operate with a different turbulence mode.
[0079] In controlling the corresponding air guide group according to the turbulence pattern, specifically, the turbulence pattern corresponding to the Xth air guide group is determined; where the Xth air guide group is one of the M air guide groups, and 1≤X≤M; M is the total number of air guide groups, M≥2.
[0080] For example, if an adult and a child are detected in the space where the air handling unit is located, there are two users. If different turbulence modes are activated, the turbulence mode corresponding to the first air guide group can be set to natural wind mode according to the adult's current location, and the turbulence mode corresponding to the second air guide group can be set to windless mode according to the child's current location.
[0081] Optionally, in some feasible implementations, the control panel of the air handling unit (such as a cabinet air conditioner) may be equipped with a button for receiving or turning off the turbulence mode. The user can press or click the button to make the controller in the air handling unit receive the turbulence mode activation or deactivation command. In other feasible implementations, the user can also send the turbulence mode activation or deactivation command to the air handling unit through the remote control of the air handling unit or an application on the terminal device, so that the controller in the air handling unit can receive the command sent by the user.
[0082] The turbulence mode of each air guide group can be determined intelligently by obtaining the user's location and body temperature status through sensors; or the turbulence mode of each air guide group can be determined based on the input of each user.
[0083] Specifically, for example, after determining the user's location using an infrared sensor, and further determining, based on a temperature sensor, that the user's current body temperature is high (e.g., the user may have just finished exercising and is in a phase of rapid heat dissipation), a first preset airflow mode, such as a pulsed airflow mode, can be intelligently selected for the user based on their body temperature. Then, based on this first preset airflow mode and the user's location, the corresponding air guide group is determined to operate, providing the user with air conditioning that matches their current state. Alternatively, the user can manually select the airflow mode, and the air handling unit will then control the corresponding air guide group to operate according to the user's selected airflow mode.
[0084] Furthermore, in some embodiments of the present invention, each air guide group is arranged along the length direction of the air outlet, and a preset distance is spaced between two adjacent air guide groups.
[0085] Specifically, as shown in Figure 3(a), multiple air guide groups are vertically arranged along the length of the air outlet and vibrate left and right along the length of the air outlet, thereby driving the flow of surrounding air. Adjacent air guide groups are spaced a predetermined distance apart along the length of the air outlet. In this embodiment, the resonant pendulum of the air guide group resonates and resonates along the length of the air outlet. As shown in Figure 3(b), multiple air guide groups are horizontally arranged along the length of the air outlet, and each air guide plate resonates and resonates along the width of the air outlet, i.e., vibrates up and down, thereby driving the flow of surrounding air. It should be noted that the air guide plate can also resonate and resonate along directions inclined to the length and width of the air outlet.
[0086] It is understandable that in the above embodiments, the resonant swing direction of the air guide plate is simply swinging in one or two directions. However, in some other embodiments, the resonant swing direction of the air guide plate can be set to be more complex, for example, it can be formed by combining two or more swing directions.
[0087] As a possible implementation method, in some embodiments of the present invention, each air guide group includes at least one air guide row, and each air guide row includes at least one air guide plate, or the air guide component includes multiple air guide rows, and each air guide row includes at least one air guide group.
[0088] When the air guide vanes operate at different vibration frequencies and amplitudes, in order to achieve different turbulence modes and zoned air supply, at least one air guide group includes at least one air guide row, and each air guide row includes at least one air guide vane; or, the air guide component includes multiple air guide rows, and at least one air guide row includes at least one air guide group. For example, the air guide component includes multiple air guide groups, at least some of the air guide groups each include multiple air guide rows, and the remaining air guide groups may use a single air guide row. As another example, the air guide component includes multiple air guide rows, at least some of the air guide rows each include multiple air guide groups, and the air guide groups between different air guide rows may be aligned (e.g., aligned along the width direction of the air outlet) or not aligned, and the remaining air guide rows may not distinguish between air guide groups.
[0089] Specifically, as shown in Figure 4(a), it can represent two air guide groups, each including an air guide row containing two air guide vanes; or it can represent an air guide component including one air guide row containing two air guide groups. The air guide vanes shown in Figure 4(a) resonate and recur along the length direction parallel to the air outlet. As shown in Figure 4(b), it also represents two air guide groups, each including an air guide row containing multiple air guide vanes; or it can represent an air guide component including one air guide row containing two air guide groups. The difference is that the air guide vanes shown in Figure 4(b) resonate and recur along the width direction parallel to the air outlet.
[0090] As shown in Figure 4(c), the air guide assembly can be represented by one air guide row, each air guide row including three air guide groups, and each air guide group including multiple air guide vanes; alternatively, the air guide component can be represented by three air guide groups, each air guide group including one air guide row. The air guide vanes shown in Figure 4(c) resonate and revolve along the length direction parallel to the air outlet. Similarly, as shown in Figure 4(d), the air guide assembly can also be represented by one air guide row, each air guide row including three air guide groups, and each air guide group including multiple air guide vanes; alternatively, the air guide component can be represented by three air guide groups, each air guide group including one air guide row. The difference is that the air guide vanes shown in Figure 4(d) resonate and revolve along the width direction parallel to the air outlet.
[0091] As shown in Figure 4(e), the air guide assembly can represent a single air guide row containing multiple (three or more) air guide groups, each containing multiple air guide vanes; or the air guide component can represent multiple (three or more) air guide groups, each containing a single air guide row. The air guide vanes shown in Figure 4(e) resonate and revolve along the length direction parallel to the air outlet. Similarly, as shown in Figure 4(f), the air guide assembly also represents a single air guide row containing multiple (three or more) air guide groups, each containing multiple air guide vanes; or the air guide component can represent a single air guide row containing multiple (three or more) air guide groups. The difference is that the air guide vanes shown in Figure 4(f) resonate and revolve along the width direction parallel to the air outlet.
[0092] Furthermore, the air outlet of the air handling equipment can also be equipped with guide vanes that resonate and oscillate along both the length and width of the outlet. In some embodiments, at least one air guide group includes multiple air guide rows, or the air guide component includes multiple air guide rows, each air guide row including multiple air guide groups, with the resonant and oscillating directions of the guide vanes in different air guide rows being different. As shown in Figure 5(a), two air guide groups can be represented, each air guide group including two air guide rows, wherein the guide vanes in one air guide row resonate and oscillate along the length of the outlet, and the guide vanes in the other air guide row resonate and oscillate along the width of the outlet; or the air guide component can be represented as including two air guide rows, each air guide row including two air guide groups, with the air guide groups between the two air guide rows aligned with each other. Figures 5(b) and 5(c) show the cases of three air guide groups and multiple (more than three) air guide groups, respectively. The arrangement of the air guides and the resonant swing direction of the air guide plates can be found in the description of Figure 5(a), which will not be repeated here. The air guide groups between two air guides do not need to be aligned with each other.
[0093] It should be noted that, Figures 4(a)-5(c) The guide vanes with the same or different resonant pendulums can be combined in a variety of ways to achieve the same or different turbulence modes, and at the same time, they can also achieve the purpose of zoned air supply.
[0094] It should be understood that the number of air guide groups proposed in the embodiments of the present invention and their specific arrangement can be set according to actual needs. The arrangement methods listed above are only exemplary and are not intended to limit the specific embodiments of the present invention.
[0095] In this embodiment, each air guide extends along a direction parallel to the width of the air outlet, along a direction parallel to the length of the air outlet, or along a direction inclined to both the length and width of the air outlet; the resonant pendulum directions of at least two air guides in the same air guide are the same or different.
[0096] Specifically, such as Figures 4(a)-5(c) As shown in any of the accompanying figures, each air guide can extend along the length direction parallel to the air outlet, thus filling the entire air outlet at certain intervals. Alternatively, a certain area of the air outlet can be left without air guides. In other embodiments, the air guides can extend parallel to the width direction of the air outlet, or extend in a direction inclined to both the length and width directions of the air outlet. Each air guide includes multiple air guide vanes. This embodiment can limit the resonant swing directions of the air guide vanes in an air guide to be the same or different. Whether they are the same or not depends on the current turbulence mode of the air guide. The turbulence mode is described below. Specifically, after the controller in the air handling equipment receives the air supply command, it first detects the turbulence mode type in the air supply command and determines the air guide group to be activated based on the sweeping type in the air supply command. It should be understood that each air guide or air guide vane of the multiple air guide groups in this embodiment can be controlled independently. Therefore, different air guides or air guide vanes can be turned on by controlling them according to different air supply commands received. Different turbulence modes can be achieved in different areas by adjusting the vibration frequency and vibration amplitude of different air guide vanes.
[0097] In some embodiments of the present invention, the turbulence mode includes a first turbulence mode, a second turbulence mode, a third turbulence mode, and a fourth turbulence mode, wherein the first turbulence mode can be a mechanical wind mode, the second turbulence mode can be a windless mode, the third turbulence mode can be a natural wind mode, and the fourth turbulence mode can be a pulsed wind mode. Controlling each air guide group to operate in the same or different turbulence modes includes: controlling at least one air guide group to be prohibited from opening to achieve the first turbulence mode; controlling at least one air guide group to operate with a first preset vibration amplitude and a first preset vibration frequency to achieve the second turbulence mode; controlling at least one air guide group to operate with a second preset vibration amplitude and a second preset vibration frequency to achieve the third turbulence mode, wherein the second preset vibration amplitude is less than the first preset vibration amplitude, and the second preset vibration frequency is less than the first preset vibration frequency; controlling at least one air guide group to operate with a third preset vibration amplitude and a third preset vibration frequency to achieve the second turbulence mode, wherein the third preset vibration amplitude is less than the second preset vibration amplitude, and the third preset vibration frequency is greater than the first preset vibration frequency.
[0098] Among them, "windless" refers to airflow with low speed and a certain degree of turbulence when it blows into the user's activity area, making it difficult for the user to feel or perceive its presence. "Natural wind" refers to airflow generated in a natural environment rather than by artificial mechanical power. Its characteristic parameters, such as wind speed, direction, frequency, and turbulence intensity, vary considerably. Natural wind is widely loved for its gentle, varied, and comfortable blowing sensation and good cooling effect. "Wind with a natural feel" shares the same characteristics as natural wind. "Pulsating wind" refers to airflow that is delivered in a wave-like pattern. When pulsating wind blows towards the user, the user can feel the wind speed alternating between high and low.
[0099] Specifically, as shown in Figure 7, the simulation results demonstrate that controlling different air guide groups to operate in different turbulence modes can achieve different airflow distributions, providing users with different wind sensations and experiences. Furthermore, when there are M air guide groups at the air outlet of the air handling unit, and M≥2, meaning that at least two of the M air guide groups operate with different vibration frequencies and amplitudes, at least two different turbulence modes can be achieved in the corresponding area, thus achieving the purpose of zoned air supply.
[0100] For example, after activating the turbulence mode, the turbulence mode corresponding to the Xth air guide group is determined. The Xth air guide group is any one of the air guide components. When the turbulence mode corresponding to the Xth air guide group is mechanical wind mode, the Xth air guide group is not activated. When the turbulence mode corresponding to the Xth air guide group is windless mode, a first preset vibration amplitude of A1 and a first preset vibration frequency of f1 are selected, and the air guide vanes in the air guide group are controlled by vibration amplitude A1 and vibration frequency f1. When the turbulence mode corresponding to the Xth air guide group is natural wind mode, a second preset vibration amplitude of A2 and a second preset vibration frequency of f2 are selected, and the air guide vanes in the air guide group are controlled by vibration amplitude A2 and vibration frequency f2. When the turbulence mode corresponding to the Xth air guide group is pulsating wind mode, a third preset vibration amplitude of A3 and a third preset vibration frequency of f3 are selected, and the air guide vanes in the air guide group are controlled by vibration amplitude A3 and vibration frequency f3.
[0101] It should be noted that the first preset vibration amplitude A1 is greater than the second preset vibration amplitude A2, the first preset vibration frequency f1 is greater than the second preset vibration frequency f2; the second preset vibration amplitude A2 is greater than the third preset vibration amplitude A3, and the third preset vibration frequency f3 is greater than the first preset vibration frequency f1.
[0102] In some embodiments of the present invention, the method further includes: when the number of users is less than a preset number threshold, controlling all air guide groups to operate in the same turbulence mode.
[0103] Specifically, if the number of people indoors is less than a preset threshold (e.g., only one user), then zoned air supply is unnecessary. All air guide groups can be controlled to operate with the same turbulence mode based on the user's air supply needs. Specifically, all air guide groups can be controlled to operate with a fourth preset vibration amplitude and a fourth preset vibration frequency, according to the user's settings, to meet the user's requirements. The fourth preset vibration amplitude and fourth preset vibration frequency are set according to the user's desired wind speed and turbulence mode. The preset vibration amplitude and preset vibration frequency listed above are merely illustrative and not intended to limit the specific implementation of this invention. For example, when the user selects the windless mode, the fourth preset vibration amplitude can be the same as the first preset vibration amplitude, both being A1, and the fourth preset vibration frequency can be the same as the first preset vibration frequency, both being f1; when the user selects the natural wind mode, the fourth preset vibration amplitude can be the same as the second preset vibration amplitude, both being A2, and the fourth preset vibration frequency can be the same as the second preset vibration frequency, both being f2; when the user selects the pulsed wind mode, the fourth preset vibration amplitude can be the same as the third preset vibration amplitude, both being A3, and the fourth preset vibration frequency can be the same as the third preset vibration frequency, both being f3.
[0104] Multiple air guide vanes with different natural frequencies can be set in the same air guide assembly to achieve different vibration frequencies; alternatively, multiple air guide vanes with different natural frequencies can be selectively driven by the same resonant actuator to achieve different vibration frequencies; or multiple resonant actuators connected to different positions on the same air guide vane can be selected to achieve different vibration frequencies. Furthermore, the vibration frequency of the air guide vane can be adjusted by utilizing the multi-order resonant frequencies of the material itself to regulate the driving frequency.
[0105] Specifically, in this embodiment, after determining the vibration frequency of the air guide vane, a corresponding vibration frequency can be generated by a resonant actuator to control the air guide vane to vibrate according to the determined vibration frequency. In frequency adjustment, it is not necessary to generate only one frequency. In different turbulence modes, the air guide vane has different vibration frequencies. The resonant actuator in this embodiment can adjust different vibration frequencies in various ways. Since the vibration frequency is related to the natural frequency of the material, the resonant actuator in this embodiment can adjust the vibration frequency by setting multiple air guides with different natural frequencies; it can also adjust the vibration frequency by selecting and driving multiple air guides with different natural frequencies; it can also adjust the vibration frequency by selecting multiple resonant actuators connected to different positions of the same air guide. When different numbers or positions of resonant actuators are used for driving, the other resonant actuators are equivalent to being loaded on the air guide, changing the mass of the air guide with the non-working actuators, thus changing the natural frequency and adjusting the vibration frequency; it can also use the first, second, third, or higher order resonant frequencies (natural frequencies) of the material, such as the air guide itself, to adjust the driving frequency and thus adjust the vibration frequency of the air guide.
[0106] It should be noted that, in addition to the aforementioned turbulence modes, this application may also set other types of turbulence modes to increase the variety of air supplied by the air handling equipment. The specific types of turbulence modes are not specifically limited here and can be set according to the user or manufacturer.
[0107] As a specific example of the present invention, such as Figure 6 shown, this Figure 6 This is a flowchart of a control method for an air handling device according to a specific embodiment of the present invention, wherein the turbulence mode is represented by a zoned air supply mode, and the resonant actuator is specifically a piezoelectric actuator. The method may include the following steps:
[0108] S601, starting up.
[0109] S602, get the number of people N in the room.
[0110] S603, determine if the value of N is greater than or equal to 2. If yes, proceed to step S604. If no, proceed to step S610.
[0111] S604, activate zoned air supply mode.
[0112] S605, determine the air delivery mode corresponding to the Xth segment of the piezoelectric fan; where 1≤X≤M; M is the total number of piezoelectric fan segments, M≥2. If the air delivery mode corresponding to the Xth segment of the piezoelectric fan is determined, proceed to step S606; if the air delivery mode corresponding to the Xth segment of the piezoelectric fan is determined to be a windless mode, proceed to step S607; if the air delivery mode corresponding to the Xth segment of the piezoelectric fan is determined to be a natural wind mode, proceed to step S608; if the air delivery mode corresponding to the Xth segment of the piezoelectric fan is determined, proceed to step S609.
[0113] S606, Mechanical Wind Mode: When the air delivery mode corresponding to the Xth segment piezoelectric fan is Mechanical Wind Mode, the Xth segment piezoelectric fan will not be turned on.
[0114] S607, Windless Mode: When the air delivery mode corresponding to the Xth segment piezoelectric fan is windless mode, the piezoelectric fan is controlled by vibration amplitude A1 and vibration frequency f1.
[0115] S608, Natural Wind Mode: When the air supply mode corresponding to the Xth segment piezoelectric fan is Natural Wind Mode, the piezoelectric fan is controlled by vibration amplitude A2 and vibration frequency f2; A1>A2, f1>f2.
[0116] S609, Pulsating wind mode: When the air supply mode corresponding to the Xth segment piezoelectric fan is the pulsating wind mode, the piezoelectric fan is controlled by the vibration amplitude A3 and the vibration frequency f3; A2>A3, f3>f1.
[0117] S610, zoned air supply mode not enabled.
[0118] S611, each piezoelectric fan operates in the same way.
[0119] It should be noted that step 601 above may specifically involve calling the control program of the air handling equipment, thereby triggering the start of the control method of the air handling equipment.
[0120] The effectiveness of the control method of the air handling equipment of the present invention is illustrated below through simulation test results. In the simulation experiment, the air handling equipment was controlled in mechanical air supply mode, windless mode, natural wind mode, and pulsed wind mode, respectively, as shown in Figures 7(a), 7(b), 7(b'), 7(c), 7(c'), 7(d), and 7(d'). Figure 7(a) shows the air outlet situation in mechanical air supply mode; Figures 7(b) and 7(b') show the air outlet situation in windless mode at different times; Figures 7(c) and 7(c') show the air outlet situation in natural wind mode at different times; and Figures 7(d) and 7(d') show the air outlet situation in pulsed wind mode at different times. It should be noted that Figure 7 is a simulation diagram of the air outlet of a single row of distributed air guide components at different frequencies, where the direction indicated by the arrow is the flow direction of the airflow output by the air handling equipment through the air outlet.
[0121] The simulation results show that in the mechanical air supply mode, the airflow is smooth along the flow direction; in the windless mode, when the air guide group is controlled by the first preset vibration amplitude and frequency, the airflow fluctuates significantly in the plane along the vibration direction of the air guide group; in the natural wind mode, when the air guide group is controlled by the second preset vibration amplitude and frequency, the airflow also fluctuates significantly in the plane along the vibration direction of the air guide group, and the airflow is relatively evenly dispersed, similar to natural wind. In the pulsed wind mode, when the air guide group is controlled by the third preset vibration amplitude and frequency, the airflow diffuses in a pulse shape in the plane along the vibration direction of the air guide group.
[0122] Furthermore, analysis of wind speed time series diagrams revealed that, for example... Figure 8 As shown, in mechanical wind mode, when the air guide group is not activated, the wind speed remains essentially unchanged over time, which corroborates the simulation results shown in Figure 7(a) above, making it suitable for long-distance air delivery. In windless mode, when the air guide group is controlled by the first preset vibration amplitude and the first preset vibration frequency, the wind speed is relatively low and has a certain turbulence intensity, providing a better windless experience for the user, which corroborates the simulation results shown in Figure 7(b) or Figure 7(b') above. In natural wind mode, when the air guide group is controlled by the second preset vibration amplitude and the second preset vibration frequency, the wind speed changes without a fixed pattern, and the turbulence intensity is greater, enabling the air handling equipment to provide a more realistic natural wind, which corroborates the simulation results shown in Figure 7(c) or Figure 7(c') above. In pulsed wind mode, when the air guide group is controlled by the third preset vibration amplitude and the third preset vibration frequency, the wind speed changes more regularly, exhibiting an overall pulsed pattern, enabling the air handling equipment to provide pulsed wind, which corroborates the simulation results shown in Figure 7(d) or Figure 7(d') above. The simulation results shown also corroborate each other.
[0123] Simulation results show that controlling the Xth air guide group to operate with different vibration frequencies and amplitudes can achieve different airflow distributions, thus realizing different air delivery modes and providing users with different airflow sensations and experiences. Furthermore, when there are M air guide groups at the air outlet of the air handling unit, and when at least two segments of the M air guide groups operate with different vibration frequencies and amplitudes, at least two different air delivery modes can be achieved in the corresponding area, achieving the purpose of zoned air delivery.
[0124] In summary, the control method of the air handling equipment in this embodiment of the invention achieves multiple different air supply modes and zoned air supply by using the same or different turbulence modes for each air guide group set at the air outlet, thereby avoiding the problem of a single air field distribution in the room. Moreover, the control logic is simple, easy to implement, and has high applicability.
