[0015] In conjunction with the above method, the present invention further provides a computer program product, including a computer program that, when executed by a processor, implements the steps of the control method for the duct machine described above.

[0016] The present invention relates to a ducted air conditioner, which includes an indoor unit and an outdoor unit, the outdoor unit having a compressor; the indoor unit having an indoor heat exchanger, an indoor fan, and an upper and lower air outlet structure, the upper and lower air outlet structure including a first air outlet and a second air outlet; on the air outlet side of the indoor heat exchanger, the first air outlet is located on the side of the indoor unit's housing, and the second air outlet is located on the bottom plate of the indoor unit's housing; when the ducted air conditioner is running after being turned on, the opening and closing of the first air outlet and the second air outlet are controlled according to the current operating mode of the ducted air conditioner; the frequency of the compressor and the speed of the indoor fan are controlled according to the indoor ambient temperature and the target temperature of the ducted air conditioner; and the air guiding direction of the currently open air outlet of the first and second air outlets is controlled according to the position of the people inside the ducted air conditioner. Therefore, by adopting an up-and-down air outlet structure (such as an up-and-down air outlet structure formed by a first air outlet and a second air outlet), and by controlling the air outlet method and air guiding direction, compressor frequency and indoor fan speed of the ducted air conditioner according to the operating mode, indoor temperature difference and human position, human comfort is improved. This ducted air conditioner is an energy-saving air conditioner.

[0017] Specifically, in the solution of this invention, for the indoor unit of a ducted air conditioner, in order to solve the problem that ducted air conditioners in related solutions cannot meet the different usage needs of users under different operating modes (such as cooling mode or heating mode) of the ducted air conditioner, an upper and lower air outlet structure is set. This upper and lower air outlet structure includes an upper air outlet located on the side of the indoor unit casing and a lower air outlet located below the indoor unit casing. An upper air guide plate (lower air guide plate 24) is provided at the upper air outlet, and a large and a small air guide plate (lower air guide plate 1 and lower air guide plate 2) are provided at the lower air outlet. When the ducted air conditioner is running, if the ducted air conditioner is in cooling mode, the upper air guide plate is controlled to open the upper air outlet, and the upper air outlet is controlled to open. The large and small air guide vanes close the lower air outlet. If the ducted air conditioner is in heating mode, the upper air guide vane closes the upper air outlet, and the large and small air guide vanes open the lower air outlet to achieve shower-like cooling or carpet-like heating. Then, based on the indoor temperature difference, the compressor frequency and indoor fan speed are controlled to improve comfort. Furthermore, based on the human position, the airflow direction of the corresponding air guide vanes in the upper and small air guide vanes is controlled to avoid airflow to people. Therefore, by setting up an upper and lower air outlet structure for the indoor unit of the ducted air conditioner, and controlling the air outlet method and direction, compressor frequency, and indoor fan speed according to the operating mode of the ducted air conditioner, the indoor temperature difference, and the human position, human comfort is improved. This ducted air conditioner is an energy-saving air conditioner.

[0018] Furthermore, in the solution of this invention, for the indoor unit of the ducted air conditioner, in order to further solve the problem that the ducted air conditioner in related solutions cannot meet the different usage needs of users under different operating modes (such as cooling mode or heating mode) of the ducted air conditioner, a heterogeneous water receiving tray (such as heterogeneous water receiving tray 31) and a variable installation structure based on a slide rail-push rod are provided to facilitate the horizontal and vertical installation of the ducted air conditioner; when the water inlet of the heterogeneous water receiving tray is placed upward, the longitudinal section of the heterogeneous water receiving tray includes two parts arranged substantially vertically (such as the second section and the third section), and the ends of both parts have a tapered portion that is inclined towards the evaporator (such as... (Sections 1 and 4) so ​​that it can serve as a water collection tray whether the ducted air conditioner is installed horizontally or vertically; based on the variable installation structure of slide rail-push rod, it has a slide rail that allows the indoor unit of the ducted air conditioner to slide horizontally and vertically. The slide rail is equipped with front pulleys and rear pulleys to drive the indoor unit of the ducted air conditioner to slide along the slide rod. The slide rail is equipped with a fixed hook to hang the indoor unit of the ducted air conditioner. The slide rail has a horizontal sliding component and a vertical sliding component. A push rod is set at the bottom of the vertical sliding component. When the push rod is extended, the indoor unit of the ducted air conditioner slides upward along the vertical sliding component of the slide rod. When the push rod is retracted, the indoor unit of the ducted air conditioner slides downward and upward along the vertical sliding component of the slide rod. By using a heterogeneous water collection tray (such as heterogeneous water collection tray 31) and a variable installation structure based on a slide rail-push rod, the installation position of the indoor unit of the ducted air conditioner can be flexibly adjusted. This allows for better integration with the indoor unit's top and bottom air outlet structure, and, based on the air conditioner's operating mode, indoor temperature difference, and human position, controls the air outlet method and direction, compressor frequency, and indoor fan speed, thereby improving human comfort. This ducted air conditioner is an energy-saving air conditioner.

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0044] Considering that ducted air conditioning systems (i.e., ducted air conditioning systems) use a single air outlet method, such as only discharging air from the side or bottom, they cannot meet the different usage needs of users in different operating modes (such as cooling or heating modes), affecting the user's comfort experience. Specifically, while side-discharged air in cooling mode can achieve the sinking of cold air, the distribution of cold air is often uneven, easily forming localized low-temperature zones in areas where people are active, causing a "direct cold air blowing" phenomenon. At the same time, the single air outlet method means that the cold air has not fully mixed with the indoor air before landing, resulting in excessively low temperatures near the air outlet and higher temperatures in corners or on the ground, creating a significant "temperature stratification" phenomenon. In heating mode, hot air, due to its lower density, rises naturally. The direction of the airflow is contrary to the rising trend of hot air, causing the hot air to fail to effectively reach areas where people are active, resulting in a delayed heating response. Users have to wait a long time to feel warmth, seriously affecting the user experience.

[0045] While bottom-discharge ducted air conditioners in heating mode help hot air rise, the heating speed is slow, and the floor temperature is difficult to raise quickly, limiting the user experience and resulting in low energy efficiency. In cooling mode, bottom-discharge ducted air conditioners blow cold air directly onto people (especially feet and legs), easily causing discomfort of "cold feet and hot head." Furthermore, the cold air sinks and accumulates on the floor, making it difficult to circulate effectively throughout the space, leading to poor comfort, low cooling efficiency, and potential health risks.

[0046] It is evident that the air outlet control of the ducted air conditioner has some shortcomings in the relevant solutions. For example, the air outlet mode of the ducted air conditioner is limited: the indoor unit of the ducted air conditioner in the relevant solutions only has one air outlet on the side or bottom, and it is impossible to switch the air supply position according to the operating mode of the ducted air conditioner (such as cooling mode or heating mode) or the user's demand for indoor ambient temperature.

[0047] For example, ducted air conditioners have low heating or cooling efficiency: when the air conditioner has side air outlets, the hot air has a low density, so it cannot effectively reach the area where people are active during heating, resulting in a delayed heating response. When the air conditioner has bottom air outlets, the cold air sinks and accumulates on the ground during cooling, making it difficult to circulate effectively throughout the space, resulting in low heat exchange efficiency and high energy consumption.

[0048] For example, ducted air conditioners have a fixed air supply direction and poor comfort: Most ducted air conditioners adopt a "side air outlet + fixed guide plate" structure, which is difficult to adapt to the air supply needs of different building structures, different locations, and different spatial levels. The temperature distribution is uneven, and there are hot and cold stratification and dead zones.

[0049] In addition, the installation location of ducted air conditioners is fixed: the relevant solutions use top installation for ducted air conditioners, which are mostly placed inside the ceiling of the house and placed horizontally, making installation and maintenance difficult.

[0050] In other words, the relevant solutions lack a duct air conditioner structure that can intelligently switch the air outlet position and dynamically adjust the air supply angle and air volume distribution according to the cooling or heating mode, so as to achieve efficient airflow organization and human thermal comfort optimization under all operating conditions.

[0051] Therefore, the present invention proposes a control method for a ducted air conditioner, specifically a control method for a ducted air conditioner with top and bottom air outlets. It adopts a multi-outlet ducted indoor unit design, using top air outlets in cooling mode and bottom air outlets in heating mode, to meet the different usage needs of users in different operating modes of the ducted air conditioner (such as cooling mode or heating mode) and improve the user's comfort experience.

[0052] According to embodiments of the present invention, a control method for a ducted air handling unit is provided, such as... Figure 1The diagram shows a flow chart of an embodiment of the method of the present invention. The ducted air conditioner has an indoor unit and an outdoor unit, the outdoor unit having a compressor; the indoor unit has an indoor fan and an air outlet structure, the air outlet structure having a first air outlet and a second air outlet, the first air outlet being able to discharge air upwards, and the second air outlet being able to discharge air downwards; of course, the indoor unit also has a heat exchange module, such as an indoor heat exchanger, i.e., an evaporator component 21. In the solution of the present invention, as... Figure 1 As shown, the control method of the duct machine includes steps S110 to S140.

[0053] In step S110, when the ducted air conditioner is running after being turned on, the indoor ambient temperature of the ducted air conditioner is obtained, and the indoor human position of the ducted air conditioner is obtained; specifically, the current operating mode of the ducted air conditioner is obtained, the indoor ambient temperature of the ducted air conditioner is obtained, the target temperature of the ducted air conditioner is obtained, and the position of the user in the current air supply area of ​​the ducted air conditioner is obtained and recorded as the indoor human position of the ducted air conditioner.

[0054] In step S120, the opening and closing of the first air outlet and the second air outlet are controlled according to the current operating mode of the duct machine.

[0055] In step S130, the frequency of the compressor and the speed of the indoor fan are controlled according to the indoor ambient temperature of the duct unit and the target temperature of the duct unit.

[0056] In step S140, the air guiding direction of the currently open air outlet in the first air outlet and the second air outlet is controlled according to the indoor human position of the air duct machine.

[0057] Figure 7 This is a flowchart illustrating the first embodiment of a control method for a ducted air conditioner with top and bottom air outlets. Figure 7 As shown, the rectifier control logic of the control method for a ducted air conditioner with top and bottom air outlets includes:

[0058] Step S1: Start the ducted air handling unit and then proceed to step S2.

[0059] Step S2: Detect the air conditioner's operating mode, detect the indoor ambient temperature, set the temperature, and then proceed to step S3.

[0060] In step S2, the room temperature is detected by a temperature sensor, and the current setting mode and temperature of the controller are detected to prepare for subsequent calculation of the difference between the ambient temperature and the set temperature and adjustment of the control mode.

[0061] Step S3: Calculate the difference between the indoor ambient temperature and the indoor set temperature, make the next judgment, and then proceed to step S4.

[0062] In step S3, the operating status of the fan and compressor is determined based on the difference between the indoor ambient temperature and the indoor set temperature.

[0063] Step S4: Determine the air outlet structure and indoor unit module of the ducted air conditioner (i.e., ... Figure 6 The system displays the operating status of the ducted air conditioner (as shown), and then executes step S5. After detecting the set mode (i.e., the air conditioning operating mode) and the temperature difference between the indoor ambient temperature and the indoor set temperature, the system determines the operating status and air outlet direction of the ducted air conditioner's air outlet structure and indoor unit module, and then opens the air guide plate.

[0064] In step S4, when the duct cooling system is running, the control module activates the side air outlets and closes the bottom air outlets. The fan runs at medium to high speed, and the cold air is blown vertically downward through the side air outlets. The cold air sinks evenly and covers the entire space, avoiding local overcooling or direct cold air blowing.

[0065] When the ductwork is in heating mode, the control module activates the bottom air outlet and closes the side air outlets. The fan runs at low speed, and hot air is blown along the ground through the bottom air outlet. The hot air rises slowly, causing the ground area to heat up rapidly and improving overall comfort.

[0066] Step S5: Detect the temperature of each area and the position of the human body, then proceed to step S6.

[0067] In step S5, the temperature values ​​of each area and the position of the human body are detected to provide data support for the control of the air guide plate.

[0068] Step S6: Control the airflow direction of the air guide plate.

[0069] In step S6, the air guide angle of the air guide plate is determined based on the detected temperature values ​​of each area and the position of the human body, so as to achieve precise heat exchange and prevent the air from blowing on people.

[0070] In the present invention, the ducted air conditioner has an indoor unit and an outdoor unit, the outdoor unit having a compressor; the indoor unit has an indoor heat exchanger, an indoor fan, and an upper and lower air outlet structure, the upper and lower air outlet structure including a first air outlet and a second air outlet; on the air outlet side of the indoor heat exchanger, the first air outlet is located on the side of the indoor unit's housing, and the second air outlet is located on the bottom plate of the indoor unit's housing; when the ducted air conditioner is running after being turned on, the opening and closing of the first air outlet and the second air outlet are controlled according to the current operating mode of the ducted air conditioner; the frequency of the compressor and the speed of the indoor fan are controlled according to the indoor ambient temperature and the target temperature of the ducted air conditioner; the air guiding direction of the currently open air outlet among the first and second air outlets is controlled according to the indoor human position of the ducted air conditioner. Therefore, by adopting an up-and-down air outlet structure (such as an up-and-down air outlet structure formed by the first air outlet and the second air outlet), and by controlling the air outlet mode and air guiding direction, compressor frequency and indoor fan speed of the duct air conditioner according to the operating mode, indoor temperature difference and human position, human comfort can be improved.

[0071] In some embodiments, a movable mounting device is provided on the outside of the indoor unit in conjunction with the indoor unit; the indoor unit also has a water tray device; the movable mounting device is, for example, a variable mounting structure based on a slide rail-push rod; the water tray device is, for example, an irregularly shaped water tray, i.e., an irregularly shaped water tray 31.

[0072] The movable installation device is slidably connected to the housing of the indoor unit and is used to move the indoor unit to allow it to be installed horizontally or vertically, thereby changing the position of the air outlet structure. Moving the indoor unit to allow it to be installed horizontally or vertically includes: moving the indoor unit so that it is installed horizontally below the ceiling or inside the ceiling of the room where it is located; or moving the indoor unit so that it is installed vertically on the side of the ceiling of the room, i.e., the indoor unit is installed on the wall on the side of the ceiling of the room.

[0073] The water tray device is located below the indoor heat exchanger and is used to receive and contain the condensate from the indoor heat exchanger when the indoor unit is installed horizontally or vertically.

[0074] The present invention proposes a control scheme for a ducted air conditioner with top and bottom air outlets. Based on the top and bottom air outlet structure design, dynamic operation control strategy and changeable air supply structure of the ducted air conditioner, it realizes flexible performance expansion of the indoor unit, adaptive adjustment of air supply mode and high-efficiency operation, thereby improving the user's comfort experience.

[0075] In the solution of this invention, the duct air conditioner features a heterogeneous water collection tray design: the heterogeneous design of the water collection tray allows for multiple installation methods of the air conditioner, expanding the application space, while the upper and lower air outlet structure allows hot air to start from the feet and cold air to not blow on people.

[0076] In some embodiments, the indoor unit also includes an indoor heat exchanger, such as an evaporator component 21; the drip tray device has a receiving cavity and an overflow-proof folded edge structure.

[0077] The accommodating cavity is used to receive and contain the condensate from the indoor heat exchanger.

[0078] The anti-overflow folded structure is located at the edge of the accommodating cavity and bends towards the indoor heat exchanger to prevent condensate from overflowing from the accommodating cavity when the indoor unit is installed horizontally or vertically.

The angle is controlled by a motor drive, and the control module controls the air guide plate (e.g., based on the heat exchange mode and data from various temperature sensors). Figure 6 The upper air guide plate 24, lower air guide plate 1, and lower air guide plate 2 shown are used for air movement. The upper air guide plate 24 is provided at the upper air outlet, and the first lower air guide plate 25 (as below the lower air guide plate 1) and the second lower air guide plate 26 (as below the lower air guide plate 2) are provided at the lower air outlet.

[0080] exist Figure 6 In the example shown, the main body of the ducted air conditioner is installed on the indoor ceiling (e.g., Figure 6 (as shown in the ceiling 12 of the roof 11) or vertically mounted on the wall (such as) Figure 6 The wall shown (13) houses a fan module and a heat exchange module inside the duct unit. The fan module includes a centrifugal fan and an air guide mechanism to drive air circulation. The air guide mechanism includes an upper air guide plate 24, a lower air guide plate 1, and a lower air guide plate 2, all driven by motors. The lower air guide plates 1 and 2 can be of different sizes or the same size; each lower air guide plate 1 and 2 is individually controlled and driven by a motor. The lower air guide plates 1 and 2 are positioned opposite each other to determine the airflow direction of the lower air outlet.

[0081] The heat exchange module includes an evaporator and a condenser, used to achieve air cooling or heating. The upper and lower air outlets are respectively located on the side (i.e., side air outlet) and bottom of the duct unit body. The upper air outlet is equipped with an adjustable air guide plate (e.g.,...). Figure 6 The upper air guide plate 24 shown is used to blow cold air downwards evenly in cooling mode to form a "shower-like" cooling effect; the bottom air outlet (i.e., the lower air outlet) is provided with an air guide channel to blow hot air along the ground in heating mode to form a "carpet-like" heating effect.

[0082] The control module includes a mode selection unit and an air outlet switching unit. The mode selection unit selects between cooling and heating modes. The air outlet switching unit controls the opening of the side or bottom air outlets based on the mode selection result and adjusts the fan speed and air guide angle to achieve optimal airflow. The mode selection unit automatically selects the cooling or heating mode and adjusts it to a comfortable temperature through temperature detection, providing real-time control and reducing user operation steps, making it more intelligent and convenient. Users can also manually change the settings. The air outlet direction is adjusted according to the cooling or heating mode: air flows from the top when cooling and from the bottom when heating.

[0083] Figure 9 This is a schematic diagram of the heterogeneous water collection tray in a ducted air conditioner with top and bottom air outlets. (Example:) Figure 6 The ducted air conditioner shown has a heterogeneous water collection tray, such as... Figure 9 The heterogeneous water collection tray 31 shown is different from the conventional rectangular water collection trays used in related solutions, which are installed below the evaporator to collect condensate. In contrast, the solution of this invention uses a heterogeneous water collection tray (e.g., [missing information]) to allow for both vertical and horizontal installation of the ducted air conditioner. Figure 9 The heterogeneous water receiving tray 31 shown can realize water receiving functions for both horizontal and vertical installation of the duct air conditioner. Figure 9 As shown, the heterogeneous water receiving tray 31 includes a water receiving container composed of several parts arranged in segments (such as a first segment, a second segment, a third segment, and a fourth segment). Specifically, as... Figure 9As shown, the arrangement of the first, second, third, and fourth sections is as follows: When the ducted air conditioner is installed horizontally, the first, second, third, and fourth sections are connected sequentially below the evaporator in the heat exchange module, along the direction from the lower air outlet of the ducted air conditioner to the fan module; the first section is generally horizontal, tilted upwards on the horizontal plane, and the angle between the first section and the horizontal plane is 45°; the second section is located to the right of the first section and is horizontal; the third section is located to the right of the second section and is vertical, with the angle between the second and third sections being 90°; the fourth section is located above the third section, generally vertical, tilted to the left on the vertical plane, and the angle between the fourth section and the vertical plane is 45°. A conventional drip tray is a rectangular container without a top, like a plate; the heterogeneous drip tray of this invention, whose shape fits the bottom shell and partition, is a drip tray with an integral structure formed by the first, second, third and fourth sections, which can catch condensate dripping from two directions without leakage.

[0084] Figure 10 This is a structural diagram of a ducted air conditioner with top and bottom air outlets (for horizontally installed ducted air conditioners). Figure 1 ,like Figure 10 As shown, the angle between the evaporator and the base plate is 45°. Figure 11 This is a structural diagram of a ducted air conditioner with top and bottom air outlets (for horizontally installed ducted air conditioners). Figure 2 ,like Figure 11 As shown, the top of the fourth section of the heterogeneous water receiving tray 31 is close to the diffuser outlet area 32 of the fan component 22 in the heat exchange module and is inclined toward the evaporator 33. Figure 12 This is a structural diagram of the drain tray in a vertically installed ducted air conditioner. When the ducted air conditioner is installed vertically, the drain tray is as follows: Figure 12 As shown.

[0085] like Figure 9 , Figure 10 , Figure 10 , Figure 11 and Figure 12 As shown, the water tray features a heterogeneous integrated design, avoiding the air outlet angle of the fan diffuser and thus not affecting normal airflow and heat exchange; the angle between the evaporator and the base plate is 45°, so horizontal or vertical installation of the duct unit does not affect the air conditioning performance.

[0086] In the solution of this invention, the installation method of the duct air conditioner is selectable by means of a heterogeneous water receiving tray design, which solves the problem of the single ceiling-mounted horizontal installation form of the duct air conditioner in related solutions and provides diversified options.

[0087] In this invention, multiple installation methods are available: a heterogeneous water collection tray design allows for horizontal or vertical installation of the duct unit; when the duct unit is installed vertically, it can be mounted vertically on a wall at the middle height of the room, or, for example, embedded in the wall at the middle height of the room, it can replace a cabinet air conditioner; simultaneously, the duct unit can also be installed horizontally as needed. This solves the problems of related solutions where duct units are typically top-mounted, mostly placed inside the ceiling, and horizontally positioned, leading to difficult installation and maintenance.

[0088] In some embodiments, the mobile mounting device includes: a sliding component, a hooking component, and a thrusting component, wherein the sliding component is such as a slide bar, a front pulley 41, and a rear pulley 43, the hooking component is such as a fixed hook 42, and the thrusting component is such as a push rod 44.

[0089] The sliding assembly includes a sliding rod and pulleys. The sliding rod has a horizontal sliding component and a vertical sliding component. The horizontal sliding component is horizontally disposed below the ceiling of the room where the indoor unit is located. The vertical sliding component is connected to the horizontal sliding component and disposed on the wall on the side of the ceiling of the room where the indoor unit is located. The pulleys are used to connect the indoor unit and drive the indoor unit to slide on the sliding rod, so that the indoor unit is in a horizontal position for horizontal installation or in a vertical position for vertical installation. The pulleys include a front pulley 41 and a rear pulley 43.

[0090] The mounting assembly is installed below the ceiling of the room where the indoor unit is located, and is used to mount the indoor unit.

[0091] The thrust assembly is located on the wall of the room on the side of the ceiling of the indoor unit and is telescopically installed at the bottom end of the vertical sliding component in the slide rod. When extended, it allows the indoor unit to slide upward along the slide rod to a horizontal position for horizontal installation, and when retracted, it allows the indoor unit to slide downward along the slide rod to a vertical position for vertical installation.

[0092] For example Figure 6 The duct unit shown has a variable mounting structure based on a slide rail and push rod to facilitate horizontal and vertical installation. Figure 13 Schematic diagram of a variable mounting structure based on a slide rail and push rod Figure 1 , Figure 14 Schematic diagram of a variable mounting structure based on a slide rail and push rod Figure 2 , Figure 15 Schematic diagram of a variable mounting structure based on a slide rail and push rod Figure 3 , Figure 16 Schematic diagram of a variable mounting structure based on a slide rail and push rod Figure 4 .like Figure 13 , Figure 14 , Figure 15 and Figure 16 As shown, the variable mounting structure based on a slide rail and push rod includes: a slide rail, a front pulley 41, a fixed hook 42, a rear pulley 43, and a push rod 44. The slide rail includes a horizontal section and a vertical section. Along the direction from the roof 11 to the wall 13, the horizontal section of the slide rail is horizontally and fixedly installed below the roof 11. The first end of the horizontal section of the slide rail in the horizontal direction is connected to the housing of the duct unit through the front pulley 41. When the duct unit is pushed to the horizontal position by the push rod 44, the fixed hook 42 can be connected to the protrusion of the duct unit housing, the push rod 44 is de-energized, and the duct unit can be kept in the horizontal position. The rear pulley 43 is placed inside the vertical section of the slide rail. The vertical section of the slide rail is vertically installed on the wall 13, and the end of the vertical section of the slide rail in the vertical direction is connected to the first end of the push rod 44 in the vertical direction. The push rod 44 is vertically installed on the wall 13.

[0093] like Figure 13 As shown, in the horizontal position of the duct unit: push rod 44 extends, and the duct unit moves upward along the slide rail, eventually reaching the horizontal installation position. Figure 14 As shown, in the vertical position of the duct unit: push rod 44 retracts, and the duct unit's own weight is used to complete the attitude change. Figure 15 As shown, the ducted air conditioner is installed in a concealed (horizontal) configuration: a variable sliding installation method allows for concealed storage of the ducted air conditioner. The ducted air conditioner is installed within the suspended ceiling 52 below the ceiling 51. Figure 16 As shown, the working mode of the ducted air conditioner (vertical installation): the ducted air conditioner is installed within the ceiling space.

[0094] In the solution of this invention, a variable installation structure based on a slide rail is used: through the slide rail-push rod structure, horizontal and vertical installation methods can be switched, adapting air supply to meet more user needs. This solves the problem that most related ducted air conditioners use a "side air outlet + fixed guide plate" structure, which is difficult to adapt to the air supply needs of different building structures, locations, and spatial levels, resulting in uneven temperature distribution, and the existence of hot and cold stratification and dead zones.

[0095] In the present invention, a variable installation structure based on a sliding rail is used: a sliding rail-push rod structure is designed to enable the ducted air conditioner to rotate 90° and change position, making it suitable for a wider range of working environments and allowing for flexible deployment of the air conditioner. In related solutions, the installation of the ducted air conditioner is "one-time and permanent," while the variable sliding rail structure allows for flexible deployment of the air conditioner, making it more convenient for users and designers to arrange. It also allows for two installation methods for the ducted air conditioner or concealed storage.

[0096] In some implementations, the specific process of controlling the opening and closing of the first air outlet and the second air outlet according to the current operating mode of the duct machine in step S120 is described in the following exemplary description.

[0097] The following is combined with Figure 2 The flowchart shown is a schematic diagram of an embodiment of the method of the present invention for controlling the opening and closing of the first air outlet and the second air outlet. It further illustrates the specific process of controlling the opening and closing of the first air outlet and the second air outlet in step S120, including steps S210 to S230.

[0098] Step S210: Determine whether the current operating mode of the duct unit is cooling mode or heating mode.

[0099] Step S220: If it is determined that the current operating mode of the duct air conditioner is cooling mode, then control the first air outlet to open and control the second air outlet to close.

[0100] Step S230: If it is determined that the current operating mode of the ducted air conditioner is heating mode, then the first air outlet is closed and the second air outlet is opened.

[0101] Figure 8 This is a flowchart illustrating a second embodiment of the control method for a ducted air conditioner with top and bottom air outlets. Figure 8 As shown, the specific control logic of the control method for a ducted air conditioner with top and bottom air outlets includes:

[0102] Step D1: Start the ducted air handling unit and then proceed to step D2.

[0103] Step D2: Detect the air conditioner's operating mode, detect the indoor ambient temperature, set the temperature, and then proceed to step D3.

[0104] In step D2, relevant parameters are detected to prepare for subsequent calculation of the difference between the indoor ambient temperature and the indoor set temperature. The room temperature is detected by a temperature sensor, and the controller's current setting mode and temperature are also detected to prepare for adjusting the control mode based on the difference between the ambient temperature and the set temperature.

[0105] Step D3: Determine the air conditioner's operating mode, then proceed to step D4.

[0106] Step D3 includes: determining the air conditioner operating mode (horizontal installation of ducted air conditioner), and then proceeding to step D4.

[0107] When the ducted air conditioner is installed horizontally, if the air conditioner is operating in cooling mode, open the upper air outlet and close the lower air outlet. Figure 17 As shown. Figure 17 This is a schematic diagram of a ducted air conditioner installed horizontally, with the upper air outlet open and the lower air outlet closed in cooling mode.

[0108] When the ducted air conditioner is installed horizontally, it adopts an upward air outlet in cooling mode to achieve uniform downward flow of cold air, improve cooling comfort, and provide a shower-like cool breeze without blowing directly on people.

[0109] When the ducted air conditioner is installed horizontally, if the air conditioner is operating in heating mode, open the lower air outlet and close the upper air outlet. Figure 18 As shown. Figure 18 This is a schematic diagram of the structure of a ducted air conditioner installed horizontally, with the lower air outlet open and the upper air outlet closed in heating mode.

[0110] When the ducted air conditioner is installed horizontally, it uses a bottom air outlet in heating mode to achieve uniform upward airflow, increase the temperature of the ground area, enhance heating efficiency, and provide carpet-like heating, with warm air starting from the feet.

[0111] Step D3 also includes: determining the air conditioner's operating mode (vertical installation of the ducted unit), and then proceeding to step D4.

[0112] When the ducted air conditioner is installed vertically, if the air conditioner is operating in cooling mode, open the upper air outlet and close the lower air outlet. Figure 19 As shown. Figure 19 This is a schematic diagram of the structure of a ducted air conditioner installed vertically, with the upper air outlet open and the lower air outlet closed in cooling mode.

[0113] When the ducted air conditioner is installed vertically and horizontally, it adopts an upward air outlet in cooling mode to achieve uniform downward flow of cold air, improve cooling comfort, and provide a shower-like cool breeze without blowing directly on people.

[0114] When the ducted air conditioner is installed vertically, if the air conditioner is operating in heating mode, open the lower air outlet and close the upper air outlet. Figure 20 As shown. Figure 20 This is a schematic diagram of the structure of a ducted air conditioner installed vertically, with the lower air outlet open and the upper air outlet closed in heating mode.

[0115] When the ducted air conditioner is installed vertically and horizontally, it adopts a bottom air outlet method in heating mode to achieve uniform rise of hot air, increase the temperature of the ground area, enhance heating efficiency, and provide carpet-like heating, with warm air starting from the feet.

[0116] In the solution of this invention, when the ductwork is in cooling mode, the control module activates the side air outlets and closes the bottom air outlets. The fan operates at medium to high speed, and cold air is blown vertically downwards through the side air outlets. The cold air sinks evenly, covering the entire space and preventing localized overcooling or direct cold air blowing. When the ductwork is in heating mode, the control module activates the bottom air outlets and closes the side air outlets. The fan operates at low speed, and hot air is blown along the ground through the bottom air outlets. The hot air rises slowly, causing the ground area to heat up rapidly and improving overall comfort.

[0117] In the solution of this invention, the ducted air conditioner adopts an upper and lower air outlet structure to meet the different usage needs of users under different operating modes (such as cooling mode or heating mode) of the ducted air conditioner, thereby improving the user's comfort experience. It solves the problem of single air outlet for ducted indoor units in related solutions, achieving both "shower-like" cooling and "carpet-like" heating effects.

[0118] In the solution of this invention, the ducted air conditioner features an upper and lower air outlet structure: It adopts a multi-outlet ducted indoor unit design. In cooling mode, it uses an upper air outlet to ensure uniform downward flow of cool air, improving cooling comfort. In heating mode, it uses a lower air outlet to ensure uniform upward flow of hot air, increasing the temperature of the ground area and enhancing heating efficiency.

[0119] In some embodiments, the specific process of controlling the frequency of the compressor and the speed of the indoor fan in step S130 based on the indoor ambient temperature of the duct unit and the target temperature of the duct unit is described in the following exemplary description.

[0120] The following is combined with Figure 3 The schematic diagram shown is a flowchart of an embodiment of the method of the present invention for controlling the frequency of the compressor and the speed of the indoor fan. It further illustrates the specific process of controlling the frequency of the compressor and the speed of the indoor fan in step S130, including steps S310 to S350.

[0121] Step S310: Determine the absolute value of the difference between the indoor ambient temperature of the ducted air conditioner and the target temperature of the ducted air conditioner, and record it as the indoor absolute temperature difference of the ducted air conditioner; the indoor ambient temperature of the ducted air conditioner, such as indoor ambient temperature T... 环 The target temperature of the ducted air conditioner, such as the indoor set temperature T. 设 The absolute value of the difference between the indoor ambient temperature and the target temperature of the ducted air conditioner, such as |Indoor Ambient Temperature T 环 -Indoor set temperature T 设 |

[0122] Step S320: Determine whether the indoor absolute temperature difference of the ducted air conditioner is greater than the first set temperature threshold, and determine whether the indoor absolute temperature difference of the ducted air conditioner is less than or equal to the second set temperature threshold; the first set temperature threshold is such as a first preset temperature value or a third preset temperature value, and the second set temperature threshold is such as a second preset temperature value or a fourth preset temperature value.

[0123] Step S330: If it is determined that the indoor absolute temperature difference of the ducted air conditioner is greater than the first set temperature threshold, then the frequency of the compressor is controlled to the set maximum frequency, and the speed of the indoor fan is controlled to the set high fan speed.

[0124] Step S340: If it is determined that the indoor absolute temperature difference of the ducted air conditioner is greater than the second set temperature threshold and less than or equal to the first set temperature threshold, then the frequency of the compressor is controlled to the set intermediate frequency, and the speed of the indoor fan is controlled to the set medium speed.

[0125] Step S350: If it is determined that the indoor absolute temperature difference of the air duct unit is less than or equal to the second set temperature threshold, then the frequency of the compressor is controlled to the set minimum frequency, and the speed of the indoor fan is controlled to the set low fan speed.

[0126] like Figure 8 As shown, the specific control logic of the control method for ducted air conditioners with top and bottom air outlets also includes:

[0127] Step D4: Calculate the indoor ambient temperature T. 环 With indoor set temperature T 设 The difference is then calculated, and step D41 or step D42 is executed to proceed to the next step of the judgment.

[0128] Step D41: In the cooling mode of the ducted air conditioner, control the operating status of the compressor and motor, and then proceed to step D5.

[0129] In step D41, under the cooling mode of the ducted air conditioner, if it is determined that |T 环 -T 设 If the first preset temperature value is reached, the compressor operating frequency will be adjusted to maximum, and the indoor fan speed will be set to high. The range of the first preset temperature value can be 3℃~5℃.

[0130] Indoor ambient temperature T 环 With indoor set temperature T 设 If the difference between the indoor ambient temperature and the set indoor temperature is large, it indicates that the room temperature is significantly different from the set temperature, the required cooling capacity is large, and the set target temperature is low. In this case, it is necessary to control the compressor to work at overclock and adjust the fan speed to the high setting to cool down quickly and improve user comfort.

[0131] In step D41, under the cooling mode of the ducted air conditioner, if it is determined that the second preset temperature value (recommended) < |T 环 -T 设 The temperature is ≤ the first preset temperature value. At this time, the compressor operates at the intermediate frequency, the inverter air conditioner adjusts the frequency adaptively, and the fan speed is set to medium. The second preset temperature value can be 1℃.

[0132] This indicates that the room temperature is at a suitable level compared to the set temperature, and the required cooling capacity is appropriate. At this point, the compressor operates at its intermediate frequency, the fan speed is adjusted to medium, and the upward airflow provides a shower-like cooling effect, achieving uniform room temperature control and preventing the "hot head, cold feet" situation.

[0133] In step D41, under the cooling mode of the ducted air conditioner, if it is determined that |T 环 -T 设 |≤ the second preset temperature value, at which point the compressor operates at a low frequency and the fan speed is adjusted to the low setting.

[0134] This indicates that the room's ambient temperature is close to the set temperature. At this point, the compressor operates at low frequency, the fan speed is adjusted to low / quiet mode to reduce energy consumption, and the upward airflow and downward airflow achieve large-scale air circulation within the room, resulting in uniform room temperature control and an improved user experience.

[0135] Step D42: In the heating mode of the ducted air conditioner, control the operating status of the compressor and motor, and then execute step D5.

[0136] In step D42, under the heating mode of the ducted air conditioner, if it is determined that |T 设 -T 环 When the third preset temperature value is reached, the compressor operates at its highest frequency, the fan speed is set to high, and air is discharged from the bottom of the air guide plate. The third preset temperature value can be between 3℃ and 5℃. When air is discharged from the bottom of the air guide plate, the lower air guide plate 1 and the lower air guide plate 2 are parallel and vertically downward at a slight angle of 15°, directing airflow towards the room (generally installed on one side of the room, slightly towards the center of the room).

[0137] This indicates a significant difference between the room's ambient temperature and the set temperature, resulting in a higher heating demand and a higher target temperature. In this case, it's necessary to control the compressor to operate at overclocked speed, set the fan speed to high, and direct warm air from the feet up. Utilizing the principle that warm air, being less dense, rises, this rapidly raises the temperature in the active areas, i.e., the lower and middle floors.

[0138] In step D42, under the heating mode of the ducted air conditioner, if it is determined that the fourth preset temperature value < |T 设 -T 环 |≤The third preset temperature value, at which point the compressor operates at the intermediate frequency and the fan speed is adjusted to the medium setting. The fourth preset temperature value can be 1℃.

[0139] This indicates that the room's ambient temperature is at a suitable level compared to the set temperature, and the required cooling capacity is appropriate. At this point, the compressor is operating normally, the fan speed is set to medium, and the downward airflow ensures even room temperature control, preventing a "hot head, cold feet" situation and achieving uniform heat exchange, thus improving heating efficiency.

[0140] In step D42, under the heating mode of the ducted air conditioner, if it is determined that |T 设 -T 环 |≤ Fourth preset temperature value, at which time the compressor operates at low frequency and the fan speed is adjusted to low.

[0141] This indicates that the room temperature is close to the set temperature. At this point, the compressor operates at low frequency, the fan speed is adjusted to low or silent mode to reduce energy consumption, and the air is directed downwards to achieve large-scale air circulation in the room, improving the user experience.

[0142] In this invention, based on the top and bottom air outlet structure of the ducted air conditioner, the air outlet direction is autonomously controlled according to the heat exchange mode. During cooling, it automatically switches to side air outlet, and during heating, it automatically switches to bottom air outlet, utilizing the sinking of cold air and the rising of hot air to improve heat exchange efficiency. This solves the problems of side air outlets in ducted air conditioners, where the low density of hot air prevents it from effectively reaching the human activity area during heating, resulting in a delayed heating response; and bottom air outlets in ducted air conditioners, where cold air sinks and accumulates on the ground during cooling, making it difficult to effectively circulate throughout the space, leading to low heat exchange efficiency and high energy consumption.

[0143] In this invention, the ducted air conditioner automatically switches between upper and lower air outlets: during cooling, it automatically switches to side air outlets, utilizing the sinking of cold air to create a "shower-like" cooling effect; during heating, it automatically switches to bottom air outlets, utilizing the rising of hot air to create a "carpet-like" heating effect. This solves the problem in related solutions where the ducted indoor unit only has one air outlet on the side or bottom, making it impossible to adjust according to the operating mode (such as cooling or heating). Simultaneously, it also solves the problems of side air outlets in ducted air conditioners, where the low density of hot air prevents it from effectively reaching the human activity area, resulting in a delayed heating response; and bottom air outlets in ducted air conditioners, where cold air sinks and accumulates on the ground during cooling, making it difficult to circulate effectively throughout the space, leading to low heat exchange efficiency and high energy consumption.

[0144] In some embodiments, the indoor unit further includes an indoor heat exchanger; on the air outlet side of the indoor heat exchanger, the first air outlet is located on the side of the housing of the indoor unit, and the second air outlet is located on the bottom plate of the housing of the indoor unit; specifically, the air outlet structure is an upper and lower air outlet structure, the first air outlet is an upper air outlet, and the second air outlet is a lower air outlet. When the indoor unit is installed horizontally, the upper air outlet is located on the side plate of the housing of the indoor unit, and the lower air outlet is located on the bottom plate of the housing of the indoor unit.

[0145] The air outlet structure also includes a first air guide plate, a second air guide plate, and a third air guide plate. The first air guide plate is disposed at the first air outlet, and the second and third air guide plates form large and small air guide plates and are disposed at the second air outlet. The first, second, and third air guide plates can all rotate to adjust the airflow direction of the corresponding air outlet. Specifically, the first air guide plate can rotate to adjust the airflow direction of the first air outlet; the second and third air guide plates can each rotate, and by cooperating with the second and third air guide plates, the airflow direction of the second air outlet can be adjusted. The first air guide plate is as shown in the upper air guide plate 24, the second air guide plate is as shown in the first lower air guide plate 25, and the third air guide plate is as shown in the second lower air guide plate 26.

[0146] In step S130, the air guiding direction of the currently open air outlet among the first air outlet and the second air outlet is controlled according to the indoor human position of the ducted air conditioner. This includes: controlling the air guide plate of the currently open air outlet among the first air outlet and the second air outlet according to the indoor human position of the ducted air conditioner, so as to adjust the air guiding angle of the air guide plate of the currently open air outlet among the first air outlet and the second air outlet, so that the air guiding direction of the currently open air outlet among the first air outlet and the second air outlet avoids the indoor human position of the ducted air conditioner, thereby achieving wind-avoiding air delivery. For details, please refer to the following exemplary description.

[0147] The following is combined with Figure 4 The diagram shows a flowchart of an embodiment of the method of the present invention for controlling the airflow direction of the currently open air outlet in the first air outlet and the second air outlet. It further illustrates the specific process of controlling the airflow direction of the currently open air outlet in the first air outlet and the second air outlet in step S130, including steps S410 to S430.

[0148] Step S410: The currently open air outlet among the first air outlet and the second air outlet is recorded as the current air outlet.

[0149] Step S420: Determine the air guiding angle of the air guide plate of the current air outlet based on the indoor human position of the air duct unit; the air guiding angle of the air guide plate of the current air outlet is an air guiding angle that allows the air blown out from the current air outlet to avoid the indoor human position of the air duct unit.

[0150] Step S430: According to the determined air guide angle of the air guide plate of the current air outlet, control the movement of the air guide plate of the current air outlet so that the air guide direction of the current air outlet avoids the indoor human position of the air duct unit, thereby achieving wind-avoiding air delivery.

[0151] like Figure 8As shown, the specific control logic of the control method for ducted air conditioners with top and bottom air outlets also includes:

[0152] Step D5: Detect the human body position and control the airflow direction of the air guide plate.

[0153] Human body detection sensors (such as infrared sensors) are installed on the inner casing of the ducted air conditioner. They can detect heat source information in real time and transmit the human body position information to the control board to achieve airflow avoidance. For example, the infrared sensor can detect the position of a human body, and the position of the human body corresponds to the activity range of the air guide plate. The air guide plate can then be controlled to avoid directing airflow within the corresponding airflow range, thus achieving airflow avoidance of people.

[0154] In this way, while ensuring the effectiveness of the cooling or heating mode, cold or hot air is prevented from blowing directly onto the human body, thus improving comfort and health.

[0155] In the solution of this invention, the dynamic operation control method for the ducted air conditioner involves designing rotatable upper and lower air guide plates to switch the air outlet direction under different operating modes. Based on load requirements or environmental parameters, the air guide plate angle is dynamically adjusted through a control algorithm to achieve precise temperature control of the area, avoiding energy waste or insufficient performance.

[0156] In the solution of this invention, a temperature sensor is used to monitor the temperature distribution at different heights in the room in real time, and an infrared sensing module is used to identify whether there are people in the room. The system can automatically adjust and control the air guide plate's air guide angle to achieve precise temperature control in the area and prevent the air from blowing on people. This solves the problem of fixed air delivery direction and poor comfort in related solutions.

[0157] In the solution of this invention, the air supply direction of the ducted air conditioner is adaptively adjusted: a temperature sensor is used to monitor the temperature distribution at different heights in real time, and an infrared sensing module is used to identify whether there are people in the room. The system autonomously adjusts and controls the air guide angle to achieve precise temperature control in specific areas and prevents the air from blowing directly on people, thus improving the user experience. This solves the problem in related solutions that cannot switch the air supply position according to the user's desired indoor temperature.

[0158] In this invention, for a top-and-bottom air-ducted air conditioner, the top-and-bottom air-discharge structure automatically switches to side airflow during cooling, utilizing the sinking of cold air to create a "shower-like" cooling effect; during heating, it automatically switches to bottom airflow, utilizing the rising of hot air to create a "carpet-like" heating effect. This air conditioner uses a heterogeneous water collection tray and can be installed horizontally or vertically as described in related solutions, achieving top-and-bottom airflow switching in both installation modes. A temperature sensor is used to monitor the temperature distribution at different heights in real time, and an infrared sensing module is used to identify whether anyone is in the room, autonomously adjusting the air guide angle to achieve precise temperature control in specific areas and prevent direct airflow onto people, thus improving the user experience.

[0159] The technical solution of this embodiment addresses a ducted air conditioner, which includes an indoor unit and an outdoor unit, with the outdoor unit having a compressor. The indoor unit includes an indoor heat exchanger, an indoor fan, and an upper and lower air outlet structure, the upper and lower air outlet structure including a first air outlet and a second air outlet. On the air outlet side of the indoor heat exchanger, the first air outlet is located on the side of the indoor unit's casing, and the second air outlet is located on the bottom plate of the indoor unit's casing. When the ducted air conditioner is running after being turned on, the opening and closing of the first air outlet and the second air outlet are controlled according to the current operating mode of the ducted air conditioner. The frequency of the compressor and the speed of the indoor fan are controlled according to the indoor ambient temperature and the target temperature of the ducted air conditioner. The air guiding direction of the currently open air outlet among the first and second air outlets is controlled according to the indoor human position in the ducted air conditioner. Therefore, by adopting an up-and-down air outlet structure (such as an up-and-down air outlet structure formed by a first air outlet and a second air outlet), and by controlling the air outlet method and air guiding direction, compressor frequency and indoor fan speed of the ducted air conditioner according to the operating mode, indoor temperature difference and human position, human comfort is improved. This ducted air conditioner is an energy-saving air conditioner.

[0160] Specifically, in the solution of this invention, to address the problem that ducted air conditioners in related solutions cannot meet the different usage needs of users in different operating modes (such as cooling mode or heating mode) of the ducted air conditioner, an upper and lower air outlet structure is set up. This structure includes an upper air outlet located on the side of the indoor unit casing and a lower air outlet located below the indoor unit casing. An upper air guide plate (as shown in lower air guide plate 24) is provided at the upper air outlet, and large and small air guide plates (as shown in lower air guide plate 1 and lower air guide plate 2) are provided at the lower air outlet. When the ducted air conditioner is running, if it is in cooling mode, the upper air guide plate is controlled to open the upper air outlet, and the upper air outlet is controlled... The system controls the upper and lower air outlets by closing the large and small air guide vanes. When the ducted air conditioner is in heating mode, it controls the upper air outlet to close and the lower air outlet to open, achieving shower-like cooling or carpet-like heating. Then, it controls the compressor frequency and indoor fan speed based on the indoor temperature difference to improve comfort. Furthermore, it controls the airflow direction of the corresponding air guide vanes in the upper and lower air guide vanes based on the user's position to avoid drafts. Therefore, by designing an upper and lower air outlet structure for the indoor unit of the ducted air conditioner, and controlling the airflow method and direction, compressor frequency, and indoor fan speed according to the air conditioner's operating mode, indoor temperature difference, and user position, it enhances user comfort. This ducted air conditioner is an energy-saving type.

[0161] Furthermore, in the solution of the present invention, in order to further solve the problem that the ducted air conditioner cannot meet the different usage needs of users in different operating modes (such as cooling mode or heating mode) of the ducted air conditioner, a heterogeneous water receiving tray (such as heterogeneous water receiving tray 31) and a variable installation structure based on slide rail-push rod are set for the indoor unit of the ducted air conditioner, so as to facilitate the horizontal and vertical installation of the ducted air conditioner; when the water inlet of the heterogeneous water receiving tray is placed upward, the longitudinal section of the heterogeneous water receiving tray includes two parts arranged in a generally vertical manner (such as the second section and the third section), and the ends of both parts have a tapered portion that is inclined towards the evaporator. (as in the first and fourth paragraphs), so that it can serve as a water collection tray whether the ducted air conditioner is installed horizontally or vertically; based on the variable installation structure of slide rail-push rod, it has a slide rail that allows the indoor unit of the ducted air conditioner to slide horizontally and vertically. The slide rail is equipped with front pulleys and rear pulleys to drive the indoor unit of the ducted air conditioner to slide along the slide rod. The slide rail is equipped with a fixed hook to hang the indoor unit of the ducted air conditioner. The slide rail has a horizontal sliding component and a vertical sliding component. A push rod is set at the bottom of the vertical sliding component. When the push rod is extended, the indoor unit of the ducted air conditioner slides upward along the vertical sliding component of the slide rod. When the push rod is retracted, the indoor unit of the ducted air conditioner slides downward and upward along the vertical sliding component of the slide rod. By using a heterogeneous water collection tray (such as heterogeneous water collection tray 31) and a variable installation structure based on a slide rail-push rod, the installation position of the indoor unit of the ducted air conditioner can be flexibly adjusted. This allows for better integration with the indoor unit's top and bottom air outlet structure, and, based on the air conditioner's operating mode, indoor temperature difference, and human position, controls the air outlet method and direction, compressor frequency, and indoor fan speed, thereby improving human comfort. This ducted air conditioner is an energy-saving air conditioner.
