[0069] To solve the technical problems of poor energy efficiency and insufficient comfort of the air conditioning system in the related art, the present disclosure provides a control method, device, air conditioning system, control equipment and storage medium.

[0070] In this disclosure, the air conditioning system includes a first air vent area and a second air vent area disposed in the space to be conditioned. Multiple air vent devices of the air conditioning system are arrayed in the first and second air vent areas respectively, and each air vent device includes a first state of horizontal air supply and a second state of vertical air supply. When the air conditioning system is in cooling mode, the first air vent area is a cooling air supply area, and the second air vent area is a cooling return air area, to achieve side-discharge of cooled air and a waterfall-like cooling effect. When the air conditioning system is in heating mode, the first air vent area is a heating return air area, and the second air vent area is a heating air supply area, to achieve downward distribution of hot air and a carpet-like heating effect. Specifically, after activating the cooling mode of the air conditioning system, the air vent devices in the first air vent area can be controlled to be in the first state, and the air vent devices in the second air vent area can be controlled to be in the second state, thereby causing the air conditioning system to enter a rapid cooling sub-mode, thus achieving rapid cooling of the space to be conditioned. Furthermore, when the air conditioning system is in cooling mode, the status of multiple air vents at different locations within the first air vent area can be controlled according to the return air temperature of the air conditioning system, thereby improving the uniformity of air supply, indoor comfort, and the energy-saving effect of the air conditioning system.

[0071] In one exemplary embodiment, reference Figures 1 to 4 As shown, a control method is provided for use in an air conditioning system. The air conditioning system is used to regulate the air in a space to be regulated. The space to be regulated can be a regular indoor space or a large public space such as a stadium or convention center; there is no limitation on the type of space.

[0072] The adjustable space includes a first air vent area and a second air vent area. Multiple air vent devices of the air conditioning system are arrayed in the first and second air vent areas respectively. Each air vent device has a first state with horizontal air vents open and a second state with vertical air vents open. In the first state, the air vent device can achieve horizontal airflow to deliver cool air laterally. In the second state, the air vent device can achieve vertical airflow to deliver hot air downwards. Of course, in the second state, the air vent device can also achieve vertical air return; this is not limited.

[0073] Among them, reference Figure 2 and Figure 3 As shown, the air conditioning system can be a central air conditioning system, which may include fan coil units 2, and fan coil units may include fan units 21, used to adjust the airflow speed. In the cooling mode, the first air vent area is the cooling air supply area, and the second air vent area is the cooling return air area, to achieve side-discharge of cooled air and a waterfall-like cooling effect; in the heating mode, the first air vent area is the heating return air area, and the second air vent area is the heating air supply area, to achieve downward distribution of hot air and a carpet-like heating effect.

[0074] In this embodiment, referenceFigure 1 The control method comprises:

[0075] S110, starting a cooling mode of the air conditioning system;

[0076] S120, controlling the air conditioning system to be in a rapid cooling sub-mode;

[0077] S130, in the cooling mode of the air conditioning system, controlling the states of the plurality of air outlet devices at different positions in the first air outlet area according to the return air temperature of the air conditioning system.

[0078] In step S110, the user can start the cooling mode of the air conditioning system through the remote controller of the air conditioning system, or through the mobile terminal connected in communication, or through the button (which can be a virtual button or a physical button) on the main machine of the air conditioning system, or through other ways, which are not limited.

[0079] In step S120, after the air conditioning system starts the cooling mode, it can automatically enter the rapid cooling sub-mode, or it can enter the rapid cooling sub-mode under the control of the user, which is not limited.

[0080] In the rapid cooling sub-mode, the air outlet devices in the first air outlet area are in the first state, and the air outlet devices in the second air outlet area are in the second state. That is, in this step, after starting the cooling mode of the air conditioning system, the air conditioning system can be controlled to be in the first state in all air outlet devices in the first air outlet area, and all air outlet devices in the second air outlet area are controlled to be in the second state, so that the air conditioning system can realize rapid return air and outlet air, thereby realizing rapid cooling to rapidly reduce the temperature of the space to be adjusted to the temperature required by the user, thereby improving the user's experience.

[0081] In step S130, it needs to be noted that after the air conditioning system starts the cooling mode, when it is in the cooling mode, due to the increase of the air supply distance, the air supply will not be timely and uniform, which will affect the indoor comfort and the energy saving effect of the air conditioning system. Based on this, in this step, when the air conditioning system is in the cooling mode, the return air temperature of the air conditioning system can be detected (for example, temperature sensors are arranged at the positions of the air outlet devices, and the return air temperature is detected through the temperature sensors of the air outlet devices in the second air outlet area).

[0082] After detecting the return air temperature, the states of the plurality of air outlet devices at different positions in the first air outlet area can be controlled according to the return air temperature, so that the load condition of the space to be adjusted and the cooling condition of the air conditioning system are more suitable, thereby improving the uniformity of air supply, indoor comfort, and also improving the energy saving effect of the air conditioning system. ​

[0083] wherein, after the first time length of the fast cooling sub-mode, if it is determined that the return air temperature is greater than or equal to the set temperature, , it indicates that the load of the space to be adjusted is still large at this time, and the air conditioning system needs to continue to maintain the current state to run, that is, the air conditioning system continues to be in the fast cooling sub-mode. It should be noted that the indoor load will change with the number of indoor active personnel, the number of indoor running equipment, the weather, etc.

[0084] wherein, after the first time length of the fast cooling sub-mode, if it is determined that the return air temperature is less than the set temperature, it indicates that the space to be adjusted is in an over-cooling state at this time, and therefore the air outlet device of the frequently active area of the human body in the space to be adjusted can be controlled to be in a closed state to avoid the frequently active area of the human body being over-cooled, affecting the comfort, and the air outlet device of the surrounding position of the space to be adjusted can be controlled to be in the first state, to maintain the temperature of the space to be adjusted to a certain extent. This mode can be recorded as a steady-state cooling sub-mode.

[0085] For example, as shown in Figure 2 and Figure 3 , the first air outlet area of the space to be adjusted can be configured as a rectangular area, which can be arranged in an array with nine air outlet devices, respectively numbered as No. 1 to No. 9, that is, nine air outlet devices are distributed in the form of 3*3. After the first time length of the fast cooling sub-mode, if it is determined that the return air temperature is less than the set temperature, the No. 2, No. 4, No. 5, No. 6, and No. 8 air outlet devices can be controlled to switch to a closed state, and the No. 1, No. 3, No. 7, and No. 9 air outlet devices can be controlled to maintain the first state to avoid the frequently active area of the human body being over-cooled, affecting the comfort, while maintaining the temperature of the space to be adjusted to a certain extent.

[0086] It should be noted that the first time length can be set according to actual needs, and the specific value thereof is not limited. The set temperature can also be set according to actual needs, and the specific value thereof is not limited. For example, the first time length can be 15 min.

[0087] In some embodiments,

[0088] As shown in Figure 2 and Figure 4 , the air outlet device 1 can be arranged in an arrangement part where the air outlet device 1 is to be arranged, which can be, for example, a ceiling surface (such as the surface of a ceiling), or other planes or non-planes, which can be selected according to actual needs, and the specific selection is not limited.

[0089] wherein, the air outlet device 1 can include a first shell 11 and a second shell 12 arranged in a sleeve. When the air outlet device 1 is installed in the arrangement part, the first shell 11 is fixedly connected with the arrangement part, and the second shell 12 is movably connected with the first shell 11, so that the second shell 12 has a first position and a second position.

[0090] The first shell 11 comprises the first air flow passage 10, and the second shell 12 comprises the second air flow passage 20. The second shell 12 is provided with a baffle structure 13 for controlling the opening and closing of the second air flow passage 20.

[0091] When the second shell 12 is in the first position, the first shell 11 and the second shell 12 form a third air flow passage, i.e. the shell walls of the first shell 11 and the second shell 12 are spaced apart to form the third air flow passage. The third air flow passage is in communication with the first air flow passage 10 to form a first air duct of the air outlet device 1, and the air outlet device 1 is in a first state at this time.

[0092] When the second shell 12 is in the second position, the first shell 11 and the second shell 12 are tightly attached, i.e. the shell walls of the first shell 11 and the second shell 12 are tightly attached, so that the third air flow passage is not formed. At this time, the first air flow passage 10 is in communication with the second air flow passage 20 to form a second air duct of the air outlet device 1, and the air outlet device 1 is in a second state at this time.

[0093] The air outlet of the first air duct faces a first direction, and the air outlet of the second air duct faces a second direction, and the first direction and the second direction are perpendicular to each other. When the air outlet device 1 is applied to an air conditioning system, a plurality of air outlet devices 1 can be provided in the air conditioning system. The placement portion of the air outlet device 1 can be a ceiling surface, i.e. the air outlet device 1 can be installed on the ceiling surface, i.e. the first shell 11 of the air outlet device 1 is fixedly connected to the ceiling surface. The connection mode can be buckle connection, fastener (such as screw) connection, adhesive connection, or a combination of multiple modes, which is not limited.

[0094] When the air outlet device 1 is installed on the ceiling surface, the air outlet of the first air duct faces the ceiling surface, and the air outlet of the second air duct is perpendicular to the ceiling surface. It should be noted that the air conditioning system is generally installed in the ceiling space of a room, and the ceiling surface refers to the lower end surface for enclosing the ceiling space. The horizontal direction refers to the horizontal direction within the allowable error range.

[0095] When the air outlet device 1 is installed on the ceiling surface, the air outlet of the first air duct faces the horizontal direction, which can be used to realize the submerged wall-bathing type cooling air supply, and the air outlet of the second air duct faces the vertical direction, which can be used to realize the carpet type down-blowing heating. That is, the embodiment can meet the requirements of submerged wall-bathing type cooling air supply, carpet type down-blowing heating, and return air for cooling and heating through the air outlet device 1.

[0096] When the air outlet device 1 is in the first state, the baffle structure 13 is controlled to close the second air flow channel 20, and the second shell 12 is controlled to be in the first position, in which case, the third air flow channel is formed between the first shell 11 and the second shell 12, so that the air outlet device 1 forms the first air duct, and at the same time, the baffle structure 13 closes the second air flow channel 20, so that the air flow in the air outlet device 1 can only be discharged through the first air duct, and the air outlet of the first air duct is in a horizontal direction, so that the wall-bathing type air supply cooling can be realized.

[0097] When the air outlet device 1 is in the second state, the baffle structure 13 is controlled to open the second air flow channel 20, and the second shell 12 is controlled to be in the second position, in which case, the first shell 11 and the second shell 12 are tightly fitted and do not form the third air flow channel, so that the first air duct is not formed, at the same time, although the first air flow channel 10 and the second air flow channel 20 are communicated to form the second air duct, and the baffle structure 13 opens the second air flow channel 20, so that the air flow in the air outlet device 1 can only be discharged or sucked (the return air can be realized) through the second air duct, and the air outlet of the second air duct is in a vertical direction, so that when the hot air flow is discharged through the second air duct, the downward blowing carpet type heating can be realized.

[0098] When the air outlet device 1 is in the second state, the baffle structure 13 is controlled to open the second air flow channel 20, and the second shell 12 is controlled to be in the second position, in which case, the first shell 11 and the second shell 12 are tightly fitted and do not form the third air flow channel, so that the first air duct is not formed, at the same time, although the first air flow channel 10 and the second air flow channel 20 are communicated to form the second air duct, and the baffle structure 13 opens the second air flow channel 20, so that the air flow in the air outlet device 1 can only be discharged or sucked (the return air can be realized) through the second air duct, and the air outlet of the second air duct is in a vertical direction, so that when the hot air flow is discharged through the second air duct, the downward blowing carpet type heating can be realized.

[0099] Wherein, the part of the first shell 11 that is sleeved with the second shell 12 is referred to as the first part, and the part of the second shell 12 that is sleeved with the first shell 11 is referred to as the second part, and the periphery of the first part and the second part is structured as a circular arc curve.

[0100] In other words, at least a portion of the shell wall of the first shell 11 is used to mate with the second shell 12, thereby achieving the fitting of the first shell 11 and the second shell 12. Correspondingly, at least a portion of the shell wall of the second shell 12 is used to mate with the first shell 11, thereby achieving the fitting of the first shell 11 and the second shell 12. The portion of the first shell 11 used to fit with the second shell 12 is denoted as the first portion, and the portion of the second shell 12 used to fit with the first shell 11 is denoted as the second portion. The first portion is at least a portion of the shell wall of the first shell 11, and the second portion is at least a portion of the shell wall of the second shell 12. The fitting of the first shell 11 and the second shell 12 is equivalent to the fitting of the first portion and the second portion.

[0101] The first part and the second part are both constructed with curved edges. On one hand, when the second housing 12 is in the second position, a tighter fit between the first and second parts is achieved. On the other hand, when the second housing 12 is in the first position, a third airflow channel is formed between the first and second parts, facilitating gas transmission and effectively reducing noise. It should be noted that in this embodiment, the curvature of the outer perimeter of the inner housing can be optimized through simulation experiments, thereby achieving the same effect as the volute on a centrifugal fan, further improving duct resistance and reducing duct noise.

[0102] The first and second arc curves share the same curvature and / or angle. It's important to note that curvature is a physical quantity describing the degree of bending of a curve; for an arc, curvature = 1 / radius (i.e., curvature is inversely proportional to radius). Therefore, "same curvature" is equivalent to "identical radii," meaning the degree of bending is the same. The "angle" here refers to the "central angle" (the angle formed by the lines connecting the two ends of the arc to the center, measured in degrees or radians). Having the same curvature and angle in both the first and second arc curves ensures a better seal between the inner and outer shells during heating and cooling, and better guides the airflow and reduces duct resistance during cooling. However, the end of the first duct needs to be horizontal to ensure horizontal airflow during cooling.

[0103] The air vent device 1 may include a first drive device 14 and a first transmission mechanism 15. The first drive device 14 drives the second housing 12 to move relative to the first housing 11 through the first transmission mechanism 15.

[0104] The first transmission mechanism 15 includes at least one of the following: a gear and rack mechanism, a hydraulic mechanism, and a cam rocker mechanism. Of course, it may also include other transmission mechanisms, which are not limited thereto.

[0105] For example, the first shell 11 can be an outer shell, and the second shell 12 can be an inner shell, the outer shell being sleeved outside the inner shell. The first driving device 14 can include an outer shell driving motor, and the first transmission mechanism 15 can be a gear and rack mechanism, which can include an outer shell driving gear and an inner shell movable rack. The outer shell fixedly installed on the ceiling has an outer shell driving motor installed on the outer surface thereof, the outer shell driving motor is installed on an outer shell driving motor fixing plate which is directly connected to the outer shell. The outer shell driving motor is directly connected with the outer shell driving gear. The inner shell is provided with the inner shell movable rack, and the cooperation between the outer shell driving gear connected by the outer shell driving motor and the inner shell movable rack on the inner shell can realize the up-down movement of the inner shell relative to the outer shell, thereby controlling the opening and closing of the first air duct (which can be used as a refrigeration air duct). At the same time, the outer shell is provided with a movable port for the inner shell movable rack to ensure the up-down movement of the inner shell movable rack. In addition, the first driving device 14 can further include a driving motor protection shell for protecting the outer shell driving motor and sealing the same to avoid the influence of dust.

[0106] Among them, the assembly composed of the outer shell driving motor and the gear and rack mechanism can be provided with one set, two sets or even more sets. When two sets are provided, the two sets of the above-mentioned assembly can be respectively arranged on both sides of the first air flow channel 10 of the outer shell to better ensure the stability of driving the movement of the inner shell.

[0107] It should be noted that in the air outlet device 1, other components or devices can also be used to realize the movement of the second shell 12 relative to the first shell 11, for example, the up-down movement of the second shell 12 relative to the first shell 11 can be realized by a telescopic cylinder.

[0108] When the air outlet device 1 is applied to a central air conditioner, since the first driving device 14 and the first transmission mechanism 15 are provided, the position of the second shell 12 can be automatically adjusted according to actual needs, thereby realizing the automatic control of whether the first air duct is conducted, and better improving the user's experience. For example, in the second position, by driving the second shell to move downward by a set distance S, it can be switched to the first position, so that the air outlet device 1 is switched from the second state to the first state.

[0109] It should be noted that the set distance S can be set according to actual conditions, and the specific value thereof can not be limited. For example, the set distance S can be set according to the height of the ceiling.

[0110] In addition, the baffle structure 13 can include a guide panel and at least one guide blade arranged on the guide panel (for example, when the guide panel is provided with a plurality of guide blades, the plurality of guide blades can form a guide louver), the guide panel is fixedly connected with the second shell 12, and the guide panel is arranged in the second air flow channel 20 close to the second air outlet, and the guide blade is used to control the opening and closing of the second air flow channel 20.

[0111] Wherein, the baffle structure 13 can further include a sweeping motor, which can control the opening and closing of the guide blade, and the angle of opening. For example, when it is necessary to cut off the second air duct, all the guide blades can be closed to cut off the second air flow channel 20, thereby cutting off the second air duct. When it is necessary to open the second air duct, at least part of the guide blades can be opened to open the second air flow channel 20, thereby opening the second air duct. It should be noted that when it is necessary to open the second air duct, the guide angle of the guide blade is also adjusted according to the actual demand to better meet the user's demand.

[0112] Wherein, the air outlet device 1 includes a filter assembly 16, the filter assembly 16 is fixedly connected with the second shell 12, the filter assembly 16 is located on the side of the baffle structure 13 away from the second air outlet, and the filter assembly 16 includes a filter port and a filter screen, the filter port is located in the second air flow channel 20, and the filter screen has a working state and a non-working state.

[0113] Wherein, in the working state, the filter screen is located at the position of the filter port for filtering the gas passing through the filter port. In this state, the filter screen is accurately moved to and covers the filter port. All the gas flowing through the filter port must pass through the filter screen, thereby being purified. When this state is applied to the return air condition, indoor air can be effectively filtered, the internal air conditioning system is kept clean, and the air quality of the supply air is improved.

[0114] In the non-working state, the filter screen is misaligned with the position of the filter port, and the gas passing through the filter port is no longer filtered. In this state, the filter screen can be controlled to move to misalign with the position of the filter port. At this time, the filter port area is unobstructed, and the air flow can pass directly without penetrating the filter screen. When this state is applied to the air outlet condition, the air resistance can be minimized to ensure the air supply volume and efficiency.

[0115] Wherein, the filter assembly 16 includes a filter panel, the filter port is arranged on the filter panel, the filter panel is provided with two guide grooves arranged oppositely, the filter screen includes two filter half screens, the two filter half screens correspond to the two guide grooves one by one, and the guide grooves are used to guide the movement of the corresponding filter half screens, so that the filter screen is switched between the working state and the non-working state.

[0116] The filter panel can be fixedly installed inside the second shell 12 (inner shell) as the basic frame of the filter assembly 16. The filter panel is provided with a filter opening, which is the core passage of the air flow. On the filter panel, two oppositely arranged guide grooves are arranged. The two guide grooves can be designed as straight sliding grooves, and their positions determine the movement trajectory of the filter screen. The filter screen is composed of two independent filter half-screens. The two filter half-screens correspond to the two guide grooves one-to-one. Each filter half-screen is precisely embedded in the corresponding guide groove through the buckle or sliding block structure thereon and can slide along the guide groove.

[0117] The two filter half-screens can be moved to both sides, so that the filter screen can be hidden on both sides of the filter opening in the non-working state, without the need to reserve more additional storage space for the entire filter screen, achieving a perfect balance between function and volume. In addition, the design of the double guide grooves provides each filter half-screen with an independent and accurate movement trajectory, ensuring that the filter half-screens will not deviate, lift or twist during movement, greatly reducing the risk of jamming or stagnation due to long-term use or dust accumulation, and improving the reliability and service life of the system.

[0118] The filter assembly 16 includes a second driving device corresponding to the filter half-screens and a second transmission mechanism, the second driving device drives the filter screen to switch between the working state and the non-working state through the second transmission mechanism. The second transmission mechanism includes at least one of the following: a gear and rack mechanism, a hydraulic mechanism, and a cam rocker mechanism, of course, other transmission mechanisms can also be included, which are not limited.

[0119] For example, the second driving device can include a filter screen driving motor, and the second transmission mechanism can be a gear and rack mechanism, which can include a filter screen gear and a filter screen rack. The filter panel can be installed with a filter screen driving motor, the filter half-screens can be translated in the corresponding guide grooves, and a reinforcing strip can be arranged in the middle position of the filter screen. The reinforcing strip is provided with a filter screen rack, and the filter screen driving motor is directly connected with the filter screen gear. Through the cooperation of the filter screen rack and the filter screen driving motor connected with the filter screen gear, the sliding or rolling of the filter half-screens along the guide grooves can be realized. The movement of the two filter half-screens can realize the opening and closing of the entire filter screen, that is, the switching of the filter screen between the non-working state and the working state.

[0120] In the case of return air when the air outlet device 1 is in the closed state, the first state and the second state, the filter assembly 16 can be controlled to be in the working state. For example, when the air outlet device 1 is used for return air, if the two filter half nets are located on both sides of the filter port at this time, that is, the filter net is in the second state, the two filter mesh driving motors can be started, so that the filter half nets are driven to move towards the filter port through the cooperation of the corresponding filter mesh gears and filter mesh racks, so that the two filter half nets are closed, and the filter net is adjusted to the working state to filter the return air. The indoor return air enters the indoor unit return air after passing through the filter net through the second air duct, so as to ensure the cleanliness of the return air.

[0121] It should be noted that for the closed state, since there is no air flow in the second air flow channel 20, the filter assembly 16 can also be maintained in the current state. That is, if the filter assembly 16 is currently in the working state, after the air outlet state is switched to the closed state, the filter assembly 16 can continue to be maintained in the working state; if the filter assembly 16 is currently in the non-working state, after the air outlet state is switched to the closed state, the filter assembly 16 can continue to be maintained in the non-working state. For the first state, since the baffle structure 13 needs to be controlled to close the second air flow channel 20 at this time, there is no air flow in the second air flow channel 20, so the filter assembly 16 can also be maintained in the current state, which will not be repeated here.

[0122] In the case of return air when the air outlet device 1 is in the closed state, the first state and the second state, the filter assembly 16 can be controlled to be in the working state. For example, when the air outlet device 1 is used for return air, if the two filter half nets are located on both sides of the filter port at this time, that is, the filter net is in the second state, the two filter mesh driving motors can be started, so that the filter half nets are driven to move towards the filter port through the cooperation of the corresponding filter mesh gears and filter mesh racks, so that the two filter half nets are closed, and the filter net is adjusted to the working state to filter the return air. The indoor return air enters the indoor unit return air after passing through the filter net through the second air duct, so as to ensure the cleanliness of the return air.

[0123] In this embodiment, the cooperation between the split filter half nets, the guide grooves, the driving devices and the transmission mechanisms can realize intelligent switching of the filtering function. In the outflow condition, the filter net can be completely removed, completely eliminating the wind resistance, ensuring the air supply volume and distance, improving the refrigeration / heating efficiency, and directly reducing the system energy consumption. In the return air state, the filter net can be accurately closed to ensure that all the return air is filtered. In addition, the double guide grooves can provide accurate independent motion trajectories for the two filter half nets, which, in combination with the driving motors and the gear and rack mechanisms, can well ensure the synchronous reverse motion of the two half nets, fundamentally avoiding the risk of jamming and greatly improving the mechanical reliability. The split hidden design enables the filter net to be folded to the sides of the filter port in the non-working state, without the need for additional storage space, perfectly solving the contradiction between multi-function integration and device miniaturization.

[0124] That is, the switching of the filter screen of the embodiment is intelligently linked with the operation mode (cooling / heating / return air) of the air conditioner, realizing full-automatic "non-sensing" operation. The filter screen only works when the return air is working, and its service life is significantly prolonged, effectively reducing the user's maintenance frequency and cost. This design ensures the cleanliness of the return air while ensuring the performance of the outflow, realizing the unification of high efficiency and air quality.

[0125] It should be noted that the air outlet device 1 can be in the form of the above-mentioned embodiments, or in other forms, which are not limited.

[0126] In this embodiment, the air outlet device can realize cold air side blowing and hot air down blowing, creating a "cascade cool" and "carpet warm" experience, and accurately meeting the high-standard demand of users for indoor comfort. At the same time, the state of the air outlet device is dynamically adjusted according to the return air temperature to solve the problem of uneven air supply, making the temperature and airflow distribution of each area of the space to be adjusted more reasonable, and improving the comfort in all directions.

[0127] Moreover, in this embodiment, the fast cooling sub-mode is entered first during cooling to quickly reduce the space temperature, shorten the high-load running time, and reduce energy consumption. After a period of operation, the running state is intelligently switched according to the return air temperature to avoid excessive cooling and heating, further improve the energy utilization efficiency, and reduce the energy cost. This embodiment is suitable for conventional indoor spaces and large public spaces such as stadiums and exhibition centers, especially for large spaces, which can achieve good air conditioning effect and meet different scene requirements by reasonably setting the air outlet area and controlling the state of the air outlet device. In addition, the fast cooling in the early stage of this embodiment can make users quickly feel comfortable temperature and reduce waiting time, and the subsequent intelligent adjustment can avoid the occurrence of over-cooling or over-heating areas, ensuring that users are always in a comfortable environment, and enhancing user satisfaction.

[0128] In one example embodiment, referring to Figures 2 to 5 An air conditioning system control method is provided. In this embodiment, the control method can include:

[0129] S210, starting the cooling mode of the air conditioning system;

[0130] S220, controlling the air conditioning system to be in a fast cooling sub-mode;

[0131] S230, after the fast cooling sub-mode runs for a first time length, determining whether the return air temperature is greater than or equal to a set temperature; if it is determined that the return air temperature is greater than or equal to the set temperature, returning to step S220; if it is determined that the return air temperature is less than the set temperature, entering step S240;

[0132] S240, controlling the air conditioning system to switch to a steady-state refrigeration sub-mode;

[0133] S250, determining whether the return air temperature is greater than or equal to the set temperature after the second time length in the steady-state refrigeration sub-mode; if it is determined that the return air temperature is greater than or equal to the set temperature, entering step S260; if it is determined that the return air temperature is less than the set temperature, entering step S280;

[0134] S260, switching the air outlet device in the central region of the space to be adjusted to the first state;

[0135] S270, determining whether the return air temperature is greater than or equal to the set temperature after the third time length; if it is determined that the return air temperature is greater than or equal to the set temperature, entering step S220; if it is determined that the return air temperature is less than the set temperature, returning to step S240;

[0136] S280, switching the air outlet device away from the second air outlet region in the space to be adjusted to the closed state, so that the air conditioning system is in a compensation refrigeration sub-mode;

[0137] S290, determining whether the return air temperature is greater than or equal to the set temperature after the fourth time length in the compensation refrigeration sub-mode; if it is determined that the return air temperature is greater than or equal to the set temperature, entering step S240; if it is determined that the return air temperature is less than the set temperature, entering step S2100;

[0138] S2100, controlling all air outlet devices in the first air outlet region to be in the closed state;

[0139] S2110, determining whether the return air temperature is greater than or equal to the set temperature after the fifth time length; if it is determined that the return air temperature is greater than or equal to the set temperature, entering step S280; if it is determined that the return air temperature is less than the set temperature, entering step S2120;

[0140] S2120, controlling the air conditioning system to be in the shutdown state.

[0141] Wherein, the steps S210-S240 can refer to the introduction of other embodiments, which will not be repeated here.

[0142] In step S250, after the air conditioning system runs for the second time length in the steady state sub-mode, the return air temperature of the air conditioning system is re-detected, and then it is determined whether the current return air temperature is greater than or equal to the set temperature. If it is determined that the return air temperature is greater than or equal to the set temperature, it indicates that the load of the space to be adjusted is increased, and the cooling effect of the air conditioning system on the space to be adjusted needs to be improved. Therefore, the air conditioning system can enter step S260.

[0143] It should be noted that the second time length can be set according to actual needs, and the specific value thereof is not limited. The second time length can be the same as or different from the first time length, and no limitation is made thereto.

[0144] In step S260, since the cooling effect of the air conditioning system on the space to be adjusted needs to be improved, the air outlet device of the central region of the space to be adjusted can be switched to the first state to concentrate the load of the central region and quickly reach the set temperature of the space to be adjusted to meet the needs of the user.

[0145] For example, the first air outlet region of the space to be adjusted can be configured as a rectangular region, which can be arrayed with nine air outlet devices, respectively denoted as No. 1 to No. 9 air outlet devices, i.e., the nine air outlet devices are distributed in the form of 3*3. After the air conditioning system runs for the first time length in the rapid cooling sub-mode, if it is determined that the return air temperature is less than the set temperature, the No. 2, No. 4, No. 5, No. 6, and No. 8 air outlet devices can be controlled to switch to the closed state, and the No. 1, No. 3, No. 7, and No. 9 air outlet devices can be controlled to maintain the first state, so that the air conditioning system enters the steady state cooling sub-mode to avoid the overcooling of the human activity region and affect the comfort, and at the same time, the temperature of the space to be adjusted is maintained to a certain extent. After the air conditioning system runs for the second time length in the steady state sub-mode, if it is determined that the return air temperature is greater than or equal to the set temperature, it indicates that the load of the space to be adjusted is increased, and the cooling effect of the air conditioning system on the space to be adjusted needs to be improved. Therefore, the No. 2, No. 5, and No. 8 air outlet devices of the space to be adjusted can be switched to the first state to concentrate the load of the central region and quickly reach the set temperature of the space to be adjusted to meet the needs of the user.

[0146] In step S270, after the air outlet device of the central region of the space to be adjusted is switched to the first state in step S260 and continues for the third time length, the return air temperature of the air conditioning system can be re-detected again, and then it is determined whether the current return air temperature is greater than or equal to the set temperature.

[0147] If it is determined that the return air temperature is greater than or equal to the set temperature, it indicates that the load of the space to be regulated is still large, and the cooling effect of the air conditioning system on the space to be regulated needs to be further improved. Then, the air outlet device of the first air outlet area is controlled to be in the first state, so that the air conditioning system switches back to the fast cooling sub-mode to quickly reduce the temperature of the space to be regulated and more quickly meet the cooling demand of the user.

[0148] If it is determined that the return air temperature is less than the set temperature, it indicates that the load of the space to be regulated is reduced and the space to be regulated is in an over-cooled state. Therefore, the cooling effect of the air conditioning system on the space to be regulated needs to be reduced. Then, the air conditioning system is controlled to switch back to the steady-state cooling sub-mode to avoid over-cooling of the human frequent activity area, affect comfort, maintain the temperature of the space to be regulated to a certain extent, avoid unnecessary energy consumption, and improve the energy efficiency of the air conditioning system.

[0149] It should be noted that the third time length can be set according to actual needs, and the specific value thereof is not limited. In addition, the third time length and the first time length can be the same or different, and no limitation is made thereto.

[0150] In step S280, since it is determined in step S250 that the load of the space to be regulated is reduced and the space to be regulated is in an over-cooled state, the cooling effect of the air conditioning system on the space to be regulated needs to be reduced. Therefore, the air outlet device far away from the second air outlet area in the space to be regulated is switched to the closed state, so that the air conditioning system is in the compensation cooling sub-mode to avoid the temperature of the space to be regulated being too low, maintain the temperature of the space to be regulated to a certain extent, better maintain the comfort of the relevant personnel, avoid unnecessary energy consumption, and improve the energy efficiency of the air conditioning system.

[0151] For example, the first air outlet region of the space to be adjusted can be configured as a rectangular region, which can be arranged in an array with nine air outlet devices, respectively numbered as No. 1 to No. 9, i.e., the nine air outlet devices are distributed in a 3*3 form. After the first time length of the rapid refrigeration sub-mode is run, if it is determined that the return air temperature is less than the set temperature, the No. 2, No. 4, No. 5, No. 6, and No. 8 air outlet devices can be controlled to switch to the closed state, and the No. 1, No. 3, No. 7, and No. 9 air outlet devices are controlled to maintain the first state, so that the air conditioning system enters the steady-state refrigeration sub-mode, to avoid the overcooling of the human activity area, affect the comfort, and at the same time maintain the temperature of the space to be adjusted to a certain extent. After the second time length of the steady-state sub-mode is run, if it is determined that the return air temperature is less than the set temperature, it indicates that the load of the space to be adjusted is reduced and is in an overcooling state, and thus it is necessary to reduce the refrigeration effect of the air conditioning system on the space to be adjusted, so that the No. 7 and No. 9 air outlet devices in the first state in the space to be adjusted are switched to the closed state, and the No. 1 and No. 3 air outlet devices continue to maintain the first state, so that the air conditioning system is in the compensation refrigeration sub-mode, which can avoid the temperature of the space to be adjusted being too low, can maintain the temperature of the space to be adjusted to a certain extent, can better maintain the comfort of the relevant personnel, can avoid unnecessary energy consumption, and can improve the energy efficiency of the air conditioning system.

[0152] In step S290, after the air conditioning system is switched to the compensation refrigeration sub-mode in step S280, and the time length of running in the compensation refrigeration sub-mode continues for a fourth time length, the return air temperature of the air conditioning system is detected again, and then it is judged whether the current return air temperature is greater than or equal to the set temperature.

[0153] If it is determined that the return air temperature is greater than or equal to the set temperature, it indicates that the load of the space to be adjusted is still large, and thus it is necessary to improve the refrigeration effect of the air conditioning system on the space to be adjusted, and the air conditioning system is controlled to switch back to the steady-state refrigeration sub-mode in step S240, to reduce the temperature of the space to be adjusted more quickly, and to better meet the refrigeration demand of the user.

[0154] If it is determined that the return air temperature is less than the set temperature, it indicates that the load of the space to be adjusted is still small and is in an overcooling state, and thus it is necessary to further reduce the refrigeration effect of the air conditioning system on the space to be adjusted, and the air conditioning system can enter step S2100.

[0155] It should be noted that the fourth time length can be set according to actual needs, and the specific numerical value thereof can not be limited. In addition, the fourth time length and the first time length can be the same or different, and no limitation is made thereto.

[0156] In step S2100, since it is determined in step S290 that the load of the space to be adjusted is still small and in an overcooled state, it is necessary to reduce the cooling effect of the air conditioning system on the space to be adjusted. Therefore, in this step, all the air vent devices in the first air vent area can be controlled to be closed. That is, the first and third air vent devices in the first air vent area are controlled to be switched to the closed state, so that all the air vent devices in the first air vent area are closed. This can not only prevent the area where people frequently move from being too cold and affecting comfort, but also avoid unnecessary energy consumption and improve the energy efficiency of the air conditioning system.

[0157] In step S2110, after all the air vents in the first air vent area are closed in step S2100 and this continues for five hours, the return air temperature of the air conditioning system can be re-detected, and then the current return air temperature can be compared with the set temperature.

[0158] If the return air temperature is determined to be greater than or equal to the set temperature, it indicates that the load on the space to be regulated has increased, and the cooling effect of the air conditioning system on the space to be regulated needs to be improved. Therefore, step S280 can be initiated, which involves controlling the air conditioning system to switch back to the compensating cooling sub-mode to lower the temperature of the space to be regulated, thereby better meeting the user's cooling needs. If the return air temperature is determined to be less than the set temperature, it indicates that the load on the space to be regulated is still relatively small, and no cooling is required. Therefore, step S2120 can be initiated.

[0159] It should be noted that the fifth duration can be set according to actual needs, and its specific value is not limited. Furthermore, the fifth duration can be the same as or different from the first duration; there are no restrictions on this.

[0160] In step S2120, since it was determined in step S2110 that the load on the space to be adjusted is still small and no cooling is required, the air conditioning system can be shut down in this step to further reduce energy consumption. Subsequently, the user can restart the air conditioning system according to their needs.

[0161] In this embodiment, through multi-stage fine adjustment, the temperature of the space to be adjusted can be precisely controlled within the set range. After the cooling mode is activated, it first enters the rapid cooling sub-mode to quickly lower the space temperature, allowing the user to quickly feel cool. Once the rapid cooling achieves a certain effect, it switches to the steady-state cooling sub-mode to prevent areas with frequent human activity from becoming too cold, ensuring comfort. If changes in the space load cause the temperature to deviate from the set value, the cooling strategy can be adjusted in a timely manner, such as improving the cooling effect in the central area or switching to the compensation cooling sub-mode, to always maintain a stable space temperature and provide users with a consistently comfortable environment, allowing them to enjoy a suitable temperature whether for daily activities or rest.

[0162] In addition, the air conditioning system of the embodiment can automatically adjust the refrigeration mode and the state of the air outlet device according to the actual load condition of the space to be adjusted. When the space load increases, the refrigeration effect is timely improved, such as switching the central area air outlet device to the first state concentrated refrigeration, or switching back to the fast refrigeration sub-mode for rapid cooling; when the space load decreases and is in an over-cooled state, the refrigeration effect is reduced, such as closing the air outlet device away from the second air outlet area or the first air outlet area, reducing unnecessary energy consumption. This intelligent adjustment method avoids the situation of over-cooling or insufficient refrigeration of the air conditioning system, effectively improves the energy utilization efficiency, reduces the operating cost, and realizes the perfect balance between comfort and energy saving.

[0163] In the fast refrigeration sub-mode and the steady-state refrigeration sub-mode, the number and state of the air outlet device are adjusted according to different needs, so that the cold air can uniformly cover the entire space to be adjusted, and the problem of local temperature unevenness is avoided. For example, in the steady-state refrigeration sub-mode, part of the air outlet device is reasonably closed, which can maintain the space temperature and avoid over-cooling in the human body frequently active area; when the refrigeration effect needs to be improved, the central area air outlet device is concentratedly opened to quickly consume the load. This flexible air outlet adjustment method improves the refrigeration effect and comfort of the air conditioning system.

[0164] The control method sets multiple refrigeration sub-modes, including a fast refrigeration sub-mode, a steady-state refrigeration sub-mode, a compensation refrigeration sub-mode, etc., which can adapt to different use scenarios and load changes. Whether it is the fast cooling demand when the space just starts refrigeration, the temperature maintenance demand when it is in stable operation, or the flexible adjustment demand when the load changes, it can be met through the corresponding sub-mode. This multi-mode switching design enhances the adaptability and flexibility of the air conditioning system, enabling it to operate stably in various complex environments and provide reliable refrigeration services for users.

[0165] When it is judged that the load of the space to be adjusted is continuously small and refrigeration is not needed, the air conditioning system can also be automatically controlled to enter the shutdown state. This function avoids the continuous operation of the air conditioning system in unnecessary cases, further reduces energy consumption, and prolongs the service life of the equipment. At the same time, it also provides convenience for users, and when the space temperature reaches the comfortable range and refrigeration is not needed, the system will automatically stop working, and when the user has a demand, the system can be restarted, truly realizing intelligent and humanized control.

[0166] In one example embodiment, referring to Figures 6 to 8 An air conditioning system is provided. The air conditioning system can include:

[0167] S310, starting a heating mode of the air conditioning system;

[0168] S320, control the fan unit of the air conditioning system to be at a first wind speed, and control the register device of the first air outlet area to be at a second state and the register device of the second air outlet area to be at the first state, so as to perform heating air supply to the space to be adjusted;

[0169] S330, when the air conditioning system is in the heating mode, every sixth time interval, control the wind speed of the fan unit according to the return air temperature of the air conditioning system.

[0170] In step S310, the starting mode of the heating mode can refer to the starting mode of the cooling mode, which will not be repeated here.

[0171] In step S320, after starting the heating mode of the air conditioning system, the register device of the first air outlet area can be controlled to be at the second state, and the register device of the second air outlet area can be controlled to be at the first state, that is, the register device of the first air outlet area can be used as the return air outlet in the heating mode, and the register device of the second air outlet area can be used as the outlet of the hot air in the heating mode, so as to realize the hot air down of the air conditioning system and realize the carpet heating effect of the space to be adjusted.

[0172] In addition, in this embodiment, the fan unit of the air conditioning system can be controlled to start at a first wind speed. The first wind speed can be set according to actual needs, and the specific value is not limited. For example, in the case that the area of the space to be adjusted is large or the initial temperature is low, the first wind speed can be set to a high gear, such as a medium wind speed or a high wind speed, so as to speed up the delivery speed of the hot air and rapidly increase the space temperature; while in the case that the space area is small or the initial temperature is not particularly low, the first wind speed can be set to a low wind speed, which can meet the heating demand and reduce energy consumption and noise.

[0173] In step S330, the sixth time interval can be set according to actual needs, and the specific value is not limited. In addition, the sixth time interval and the first time interval can be the same or different, and the specific value is not limited.

[0174] The wind speed gear of the fan unit can be divided into multiple gears, for example, a high gear with the maximum wind speed, a low gear with the minimum wind speed, and a medium gear with the moderate wind speed. Of course, more detailed division can be made, and the specific value is not limited.

[0175] Every sixth time interval, if it is determined that the return air temperature is greater than or equal to the sum of the set temperature and the set temperature difference, and the wind speed of the fan unit is not the lowest gear wind speed, the wind speed of the fan unit is controlled to decrease by one gear; if the wind speed of the fan unit is already at the lowest gear wind speed at this time, the current gear can be maintained.

[0176] If the return air temperature is determined to be less than the sum of the set temperature and the set temperature difference, and the air speed of the fan unit is not the highest speed, the air speed of the fan unit is controlled to increase by one level every sixth time length. If the air speed of the fan unit is already the highest speed, the air speed of the fan unit is controlled to maintain the current level.

[0177] It should be noted that the set temperature difference can be set according to actual needs, and the specific value thereof is not limited.

[0178] For example, the air speed levels of the fan unit are L1, L2 and L3 from high to low, the L1 level corresponds to the highest air speed, and the L3 level corresponds to the lowest air speed. The set temperature difference ΔT can be 3°C. When the heating mode is started, all the air outlets are opened, and the fan unit operates at the L1 level of the air speed. At this time, the channel between the indoor and outdoor air outlets is closed, that is, the air outlet devices are all in the second state. The indoor return air is heated by the unit, and the hot air is vertically sent to the ground through the air outlet devices in the second air outlet area. After the hot air reaches the ground, it naturally rises and warms the entire space. At the same time, the indoor return air temperature and the set temperature are collected. After every sixth time length, the return air temperature and the set temperature are compared and judged, and the air speed of the fan unit is controlled based on the comparison result, so as to adjust the indoor comfort and improve the equipment operation parameters and energy efficiency.

[0179] In this embodiment, in terms of heating effect, the hot air is sent downward to form a carpet-like warmness. The different air outlet areas are controlled to allow the hot air to blow out from near the ground and naturally diffuse throughout the space, solving the problem of low temperature at the lower part in the traditional air supply mode, making the space temperature rise uniformly, and allowing the initial air speed of the fan unit to be flexibly set according to the space area and the initial temperature. When the space is large or the temperature is low, a high air speed is used to quickly raise the temperature, and when the space is small or the temperature is acceptable, a low air speed is used to reduce energy consumption and noise. In terms of energy utilization, the air speed of the fan unit is dynamically adjusted based on the return air temperature. Every certain time length, the air speed of the fan unit is increased or decreased according to the sum of the return air temperature, the set temperature and the set temperature difference. This adjustment can reduce the power of the fan unit while meeting the heating demand, avoid excessive heating, effectively reduce energy consumption, improve energy utilization efficiency, and meet the requirements of energy saving and environmental protection. In terms of user experience, the air speed and air supply mode are accurately controlled, the indoor temperature can be stabilized in the comfortable range set by the user, a suitable and uniform indoor environment is created for the user, and the life quality and satisfaction of the user are improved. Moreover, in terms of equipment operation, reasonable air speed setting reduces the excessive wear and tear of components such as the fan unit, prolongs the service life of the equipment, and optimizes energy utilization to improve the overall energy efficiency of the equipment, making the air conditioning system more stable and efficient in long-term operation, reducing the probability of equipment failure and maintenance cost.
