[0002] Existing ducted air conditioners are connected to multiple air outlets through air ducts and deliver air to multiple rooms. Since ordinary air conditioners only have two ambient temperature sensors, one for the machine itself and one for the controller, which is usually placed in the corridor or living room, there are no temperature sensors in the room. Therefore, the room temperature can only be adjusted by manually controlling the damper to adjust the temperature of each room, which is cumbersome to operate and cannot accurately control the temperature.

[0003] Some existing technologies install ambient temperature sensors in each room through independent wiring to collect the temperature of each room for control. However, due to the large number of rooms and the long distance between the rooms, the wiring of the external sensors is relatively messy, the installation cost of installing wiring troughs is high, and the sensor maintenance and replacement is troublesome.

[0025] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0026] Figure 1 The figure shows a flow chart of the control method of the duct machine provided by the present invention. Figure 1 As shown, the method includes:

[0027] S110, receiving the regional temperature and regional humidity transmitted by the air box in the area to be regulated;

[0028] S120 , based on the regional temperature and the regional humidity, controlling the compressor operating frequency and / or the air valves corresponding to the multiple areas to be adjusted.

[0029] It should be noted that the ducted air conditioner is connected to multiple dampers (air outlets) through an air duct. The multiple dampers correspond one-to-one to multiple areas to be adjusted, and each area to be adjusted corresponds to an air box.

[0030] The air box is an intelligent hardware for healthy air management. It is an intelligent control terminal that integrates multiple functions such as intelligent control and air detection. It can monitor the temperature, humidity and air quality information in the environment in real time and accurately, and can also provide users with historical monitoring data of the indoor environment.

[0031] It should also be noted that the air boxes corresponding to the multiple areas to be adjusted are all communicated with the area controller in the duct machine. The communication connection can be achieved through a communication response mechanism or by setting address mutual recognition.

[0032] It is easy to understand that in step S110, the regional temperature and regional humidity of multiple areas to be adjusted are obtained respectively through the air boxes set in multiple areas to be adjusted, and based on the communication connection with the regional controller of the duct machine, the obtained regional temperature and regional humidity are transmitted to the regional controller, and the regional controller is used to integrate and analyze the data transmitted from each area to be adjusted.

[0033] The system assumes that multiple areas to be regulated all have environmental regulation requirements, and the air valves corresponding to the areas to be regulated are opened by default. Of course, adjustments can also be made based on the actual opening or closing status of the air valves corresponding to the areas to be regulated, which is not specifically limited here.

[0034] It should be noted that the air box can collect the regional temperature and regional humidity of the area to be adjusted in real time, or it can collect the regional temperature and regional humidity of the area to be adjusted according to a set time, which is not specifically limited here.

[0035] In step S120, after the zone controller receives the zone temperature and zone humidity of each area to be adjusted, it controls the compressor operating frequency and at least one of the air valves corresponding to the multiple areas to be adjusted based on the received multiple zone temperatures and zone humidity, so that the temperature and humidity of the corresponding area to be adjusted meet user requirements.

[0036] That is to say, when the regional temperature and regional humidity are obtained, only the compressor operating frequency can be adjusted according to the regional temperature and regional humidity, or only the air valves corresponding to multiple areas to be adjusted can be adjusted according to the regional temperature and regional humidity, or the compressor operating frequency and the air valves corresponding to multiple areas to be adjusted can be adjusted at the same time according to the regional temperature and regional humidity.

[0037] It should be noted that in addition to controlling the compressor operating frequency and the damper, other operating parameters of the ducted air conditioner may also be adjusted, such as the fan speed and the damper opening angle, which are not specifically limited here.

[0038] In addition, take the ducted air conditioner with 3 areas to be adjusted as an example. Figure 2 A control schematic diagram of the duct air conditioner control method provided by the present invention is shown.

[0039] like Figure 2As shown, the outdoor unit is connected to the indoor unit, which is equipped with a zone controller. The zone controller integrates and analyzes the regional temperature and humidity of the regulated area 1, regulated area 2, and regulated area 3. The regional temperature and humidity are collected by the air box installed in each regulated area.

[0040] In this embodiment, the regional temperature and regional humidity transmitted by the air box in the area to be adjusted are received, and based on the regional temperature and regional humidity, the compressor operating frequency and / or the air valves corresponding to the multiple areas to be adjusted are controlled so that the ambient temperature and humidity of each area to be adjusted reach the set temperature and set humidity, respectively. This method uses air boxes set in multiple areas to be adjusted to collect the precise temperature and humidity of the multiple areas to be adjusted, and then controls the compressor operating frequency and air valves based on the collected regional temperature and regional humidity to achieve the purpose of accurately adjusting the temperature and humidity of the multiple areas to be adjusted. This overcomes the defects of existing ducted air conditioners that cannot accurately control the temperature of multiple areas and do not control humidity, and realizes precise control of the temperature and humidity of multiple areas, effectively improving the user experience.

[0041] On the basis of the above embodiments, further, based on the regional temperature and regional humidity, the compressor operating frequency and / or the air valves corresponding to multiple areas to be adjusted are controlled. The following describes the compressor operating frequency adjustment process and the process of controlling the air valves corresponding to the areas to be adjusted respectively.

[0042] In a specific embodiment, the steps of controlling the air valves corresponding to multiple areas to be adjusted include: obtaining the target area temperature and target area humidity corresponding to the multiple areas to be adjusted; calculating the regional temperature difference between the regional temperature of each area to be adjusted and the target area temperature; calculating the regional humidity difference between the regional humidity of each area to be adjusted and the target area humidity; and adjusting the valve opening of the air valve corresponding to each area to be adjusted according to the regional temperature difference and the regional humidity difference.

[0043] It should be noted that one ducted air conditioner corresponds to multiple areas to be adjusted. Different areas to be adjusted have different area sizes and correspond to different environmental adjustment requirements. The environmental adjustment requirements can be specifically the target area temperature and target area humidity corresponding to each area to be adjusted. The target area temperature and target area humidity can be set according to the area and specific circumstances, and are not specifically limited here.

[0044] For example, in one embodiment, the current regional temperature of the area 1 to be adjusted is 28 degrees Celsius, the target regional temperature is 26 degrees Celsius, the current regional humidity is 65%, and the target regional humidity is 50%.

[0045] For another example, in another embodiment, the current regional temperature of the area 2 to be adjusted is 28 degrees Celsius, the target regional temperature is 24 degrees Celsius, the current regional humidity is 55%, and the target regional humidity is 50%.

[0046] For another example, in yet another embodiment, the current regional temperature of the area to be adjusted 3 is 28 degrees Celsius, the target regional temperature is 20 degrees Celsius, the current regional humidity is 60%, and the target regional humidity is 50%.

[0047] It can be understood that the compressor operating frequency is controlled. Specifically, the target regional temperature and target regional humidity corresponding to multiple areas to be adjusted are first obtained. Since the regional temperature and regional humidity of the areas to be adjusted have been obtained in advance, the difference between the regional temperature of each area to be adjusted and the target regional temperature, that is, the regional temperature difference, can be calculated at this time. At the same time, the difference between the regional humidity of each area to be adjusted and the target regional humidity, that is, the regional humidity difference, can also be calculated.

[0048] Furthermore, the valve opening of the air valve corresponding to each area to be regulated can be adjusted based on the calculated regional temperature difference and regional humidity difference. Generally speaking, the larger the regional temperature difference, the larger the valve opening of the corresponding air valve, and vice versa.

[0049] For regional humidity, when the difference between the regional humidity and the target regional humidity is relatively large, indoor humidification equipment can also be used to make the regional humidity reach the target regional humidity as soon as possible.

[0050] In another specific embodiment, the step of controlling the compressor operating frequency includes: determining the maximum regional temperature difference among multiple regional temperature differences corresponding to multiple regions to be adjusted; determining the maximum regional humidity difference among multiple regional humidity differences corresponding to multiple regions to be adjusted; and controlling the compressor operating frequency according to the maximum regional temperature difference and the maximum regional humidity difference.

[0051] It can be understood that the compressor operating frequency is controlled. Specifically, based on the regional temperature difference and regional humidity difference corresponding to each area to be adjusted obtained by the above calculation, based on the multiple regional temperature differences and multiple regional humidity differences corresponding to multiple areas to be adjusted, the maximum regional temperature difference among the multiple regional temperature differences and the maximum regional humidity difference among the multiple regional humidity differences can be determined.

[0052] Furthermore, the compressor operating frequency is controlled based on the determined maximum regional temperature difference and maximum regional humidity difference. In detail, if the compressor operates at the compressor operating frequency corresponding to the maximum regional temperature difference and the maximum regional humidity difference, it will definitely be able to meet the temperature and humidity requirements of other areas to be adjusted except the area to be adjusted corresponding to the maximum regional temperature difference and the area to be adjusted corresponding to the maximum regional humidity difference.

[0053] Generally speaking, the greater the regional temperature difference, the higher the compressor operating frequency, and vice versa. The greater the regional humidity difference, the higher the compressor operating frequency, and vice versa.

[0054] In this embodiment, by obtaining the target regional temperature and target regional humidity corresponding to multiple areas to be adjusted, the regional temperature difference between the regional temperature of each area to be adjusted and the target regional temperature, as well as the regional humidity difference between the regional humidity of each area to be adjusted and the target regional humidity are calculated, and the maximum regional temperature difference among the multiple regional temperature differences, as well as the maximum regional humidity difference among the multiple regional humidity differences, are determined. Thus, the valve opening of the air valve corresponding to each area to be adjusted is adjusted according to the regional temperature difference and the regional humidity difference, and the compressor operating frequency is controlled according to the maximum regional temperature difference and the maximum regional humidity difference. This method controls the compressor operating frequency and the air valve according to the regional temperature and regional humidity collected by the air box to achieve the purpose of accurately adjusting the temperature and humidity of multiple areas to be adjusted, overcoming the defects of existing ducted air conditioners that cannot accurately control the temperature of multiple areas and do not perform humidity control, realizing accurate control of the temperature and humidity of multiple areas, and effectively improving the user experience.

[0055] On the basis of the above embodiment, the compressor operating frequency and / or the air valves corresponding to the multiple areas to be adjusted are further controlled, which then includes: determining that the regional temperatures of the multiple areas to be adjusted reach the target regional temperatures, and the regional humidity of the multiple areas to be adjusted reaches the target regional humidity; controlling the compressor operating frequency to the set compressor operating frequency, and controlling the valve opening of the air valve corresponding to the area to be adjusted to the minimum valve opening.

[0056] It is easy to understand that after controlling the compressor operating frequency and / or the air valves corresponding to multiple areas to be adjusted, the regional temperature and regional humidity of each area to be adjusted are continuously monitored in real time. When it is determined that the regional temperature of multiple areas to be adjusted reaches the target regional temperature, and the regional humidity of multiple areas to be adjusted reaches the target regional humidity, it means that the environmental requirements of each area to be adjusted have been met. At this time, the compressor no longer needs to operate at a high operating frequency, and the valve opening of the air valve does not need to be particularly large. In order to avoid waste of resources, the compressor operating frequency is controlled to the set compressor operating frequency. At the same time, the valve opening of the air valve corresponding to the area to be adjusted is controlled to the minimum valve opening.

[0057] The compressor operating frequency may be set according to actual conditions and is not specifically limited herein. For example, in a specific embodiment, the compressor operating frequency is set to the minimum compressor operating frequency.

[0058] In this embodiment, by determining that the regional temperatures of multiple areas to be adjusted reach the target regional temperatures and the regional humidities of multiple areas to be adjusted reach the target regional humidity, the compressor operating frequency is controlled to the set compressor operating frequency, and the valve opening of the air valve corresponding to the area to be adjusted is controlled to the minimum valve opening, thereby avoiding unnecessary waste of resources.

[0059] On the basis of the above embodiment, it is further determined that the regional temperature of multiple areas to be adjusted reaches the target regional temperature, and the regional humidity of multiple areas to be adjusted reaches the target regional humidity. Specifically, there are two situations: one is that the regional humidity of the area to be adjusted with the air valve opened reaches the target regional humidity first, and the corresponding regional temperature reaches the target regional temperature later; the other is that the regional temperature of the area to be adjusted with the air valve opened reaches the target regional temperature first, and the corresponding regional humidity reaches the target regional humidity later.

[0060] In a specific embodiment, it is determined that the regional temperature of a to-be-adjusted area with an open air valve reaches the target regional temperature after a first period of time; and it is determined that the regional humidity of the to-be-adjusted area reaches the target regional humidity after a second period of time; wherein the first period of time is greater than the second period of time, that is, it takes longer for the regional temperature of the to-be-adjusted area to reach the target regional temperature.

[0061] At this time, the corresponding air valve is controlled to be continuously opened, and the air box is turned on for humidification until the regional temperature of the area to be adjusted reaches the target regional temperature and the regional humidity of the area to be adjusted reaches the target regional humidity.

[0062] In another specific embodiment, it is determined that the regional temperature of the area to be adjusted reaches the target regional temperature after a first period of time; and it is determined that the regional humidity of the area to be adjusted reaches the target regional humidity after a second period of time; wherein the first period of time is less than the second period of time, that is, it takes longer for the regional humidity of the area to be adjusted with the air valve opened to reach the target regional humidity.

[0063] At this time, the corresponding air valve is controlled to be closed for m minutes and opened for n minutes until the regional temperature of the area to be adjusted reaches the target regional temperature and the regional humidity of the area to be adjusted reaches the target regional humidity.

[0064] Wherein, m and n are both positive integers. The specific values ​​of m and n can be intelligently and dynamically adjusted according to the adjustment effect. Moreover, m and n can be the same value or different values, which are not specifically limited here.

[0065] It should be noted that the first duration and the second duration in the above two specific embodiments can be set according to specific circumstances and are not specifically limited here.

[0066] In this embodiment, by comparing the time it takes for the regional temperature of the area to be adjusted to reach the target regional temperature with the time it takes for the regional humidity of the area to be adjusted to reach the target regional humidity, different treatments are made to the corresponding air valves based on different comparison results to achieve the purpose of accurately adjusting the temperature and humidity of multiple areas to be adjusted. This overcomes the defects of existing duct machines that cannot accurately control the temperature of multiple areas and do not perform humidity control, realizes accurate control of the temperature and humidity of multiple areas, and effectively improves the user experience.

[0067] On the basis of the above embodiment, further, each area to be adjusted corresponds to a damper; the control method also includes: determining the control time for the regional temperature of multiple areas to be adjusted to reach the target regional temperature; determining the area to be adjusted corresponding to the longest control time among multiple control times; setting the damper of the area to be adjusted corresponding to the longest control time to be a normally open damper, and the normally open damper opens when the duct machine starts to run.

[0068] It can be understood that when adjusting the regional temperature of the area to be adjusted, the control time for the regional temperature of each area to be adjusted to reach the target regional temperature can be obtained. The control time starts at the time point when the regional temperature transmitted by the air box is received and ends at the time when the regional temperature reaches the target regional temperature.

[0069] On the basis of obtaining the control times corresponding to multiple areas to be adjusted, the longest control time among the multiple control times and the area to be adjusted corresponding to the longest control time can be determined. The damper corresponding to the area to be adjusted can be further determined, and the damper corresponding to the area to be adjusted with the longest control time can be set as a normally open damper. The normally open damper opens when the duct machine starts running, and continues to run without closing when the duct machine does not stop running. In this way, when the regional temperature of the area to be adjusted next time is adjusted, the control time for the regional temperature of the area to be adjusted to reach the target regional temperature can be effectively reduced.

[0070] It should be noted that, in this embodiment, the normally open damper can also be set according to the maximum time for the regional humidity to reach the target regional humidity. The details are the same as above and will not be elaborated here.

[0071] In this embodiment, by determining the control time for the regional temperature of multiple areas to be adjusted to reach the target regional temperature, and determining the area to be adjusted corresponding to the longest control time among the multiple control times, the damper corresponding to the area to be adjusted with the longest control time is set as a normally open damper, which effectively reduces the control time for the regional temperature of the area to be adjusted to reach the target regional temperature, thereby improving the user experience.

[0072] Based on the above embodiment, the method further includes: identifying the user's identity information; determining that the user is a preset target user; and adjusting the regional temperature, regional humidity and regional air quality of the corresponding area to be adjusted according to the location information of the preset target user.

[0073] It is understandable that each area to be adjusted is provided with multi-directional cameras, and the cameras are connected to the area controller via wireless.

[0074] Specifically, when any user is identified in the area to be adjusted, the identity information of the user is identified, and the facial information of the user is matched with the preset identity information stored in the system database.

[0075] If a match is found, the user is determined to be the preset target user, and the location information of the preset target user is obtained. Then, according to the location information of the preset target user, the regional temperature, regional humidity and regional air quality of the area to be adjusted are adjusted, that is, the regional temperature, regional humidity and regional air quality are adjusted to the temperature, humidity and air quality desired by the preset target user.

[0076] The preset target users can be set according to actual conditions or needs and are not specifically limited here. For example, the preset target users can be people with special needs, such as the elderly and children; or they can be relatively important people.

[0077] It should be noted that the preset target temperature, humidity and air quality desired by the user are pre-stored in the system database and can be directly called.

[0078] If the user's facial information cannot be matched with the preset identity information in the system database, no further action will be taken.

[0079] In this embodiment, the user's identity information is identified and the user is determined to be a preset target user. The regional temperature, humidity, and air quality of the area to be adjusted are then adjusted based on the preset target user's location information. This method allows for customized adjustments to the temperature, humidity, and air quality of the area to be adjusted based on the specific needs of a single user, further enhancing the user experience.

[0080] On the basis of the above embodiments, the method further includes: for each area to be adjusted, storing historical adjustment information of the area to be adjusted, the historical adjustment information includes adjustment time, historical area temperature, historical area humidity and air valve opening information; according to the historical adjustment information of each area to be adjusted, adjusting the valve opening of the air valve of the area to be adjusted.

[0081] It is understandable that each time the temperature and humidity of each area to be adjusted are adjusted, all historical adjustment information corresponding to the area to be adjusted is stored. The historical adjustment information specifically includes the adjustment time, the historical area temperature corresponding to the adjustment time, the historical area humidity and the air valve opening information.

[0082] Based on the above historical adjustment information, the historical temperature adjustment progress of the area to be adjusted can be analyzed. For example, the area temperature of the area to be adjusted is adjusted from the first temperature to the second temperature within the first time, and the state of the air valve opening during this process is known.

[0083] Based on the analyzed historical temperature adjustment progress, the real-time temperature adjustment process can be guided. For example, if the temperature of the area to be adjusted needs to be adjusted from a first temperature to a second temperature within a second time, and the second time is shorter than the first time, the damper opening can be increased based on the historical adjustment information to meet the above requirement.

[0084] It should be noted that the content of this embodiment is also applicable to humidity control and will not be elaborated here.

[0085] In this embodiment, the historical adjustment information of each area to be adjusted is stored, and the valve opening of the air valve in the area to be adjusted is adjusted based on the historical adjustment information of each area to be adjusted. This method can achieve more precise control of the temperature of the area to be adjusted by summarizing the historical adjustment information.

[0086] On the basis of the above embodiment, further, the duct unit is connected to an air purifier, and also includes: receiving regional air quality information transmitted by the air box in the area to be adjusted; and determining to turn on the air purifier to adjust the indoor air quality according to the regional air quality information.

[0087] It can be understood that the duct unit is connected to the indoor air purifier, the air box collects the regional air quality information of the area to be regulated, and transmits the collected regional air quality information to the regional controller. The regional controller determines whether it is necessary to turn on the air purifier to purify the indoor air based on the received regional air quality information.

[0088] Specifically, the regional air quality information includes the content of each air component. If the content of each air component exceeds the standard, it means that the air purifier needs to be turned on to purify the indoor air. Otherwise, the air purifier does not need to be turned on.

[0089] In this embodiment, the air quality information transmitted by the air box in the area to be regulated is received, and based on this information, the air purifier is activated to adjust the indoor air quality. This method not only controls the temperature and humidity of the area to be regulated, but also promptly purifies the indoor air quality, providing a comfortable environment for indoor users and enhancing their experience.

[0090] Additionally, in one embodiment, Figure 3 The figure shows the overall flow chart of the control method of the duct air conditioner provided by the present invention.

[0091] like Figure 3 As shown, first, the air boxes in multiple areas to be adjusted establish communication connections with the area controller (or WIFI control module), so that the air boxes will transmit the collected area temperature and area humidity to the area controller.

[0092] Then, a regional temperature difference between the regional temperature of the to-be-adjusted region with the air valve opened and the target regional temperature is calculated, and a maximum regional temperature difference among the multiple regional temperature differences is determined.

[0093] At the same time, the regional humidity difference between the regional humidity of the area to be regulated with the air valve opened and the target regional humidity is calculated, and the maximum regional humidity difference among the multiple regional humidity differences is determined.

[0094] During this process, the regional temperature difference and regional humidity difference corresponding to the area to be adjusted with the air valve opened will be updated in real time. The regional temperature difference and regional humidity difference of the area to be adjusted with the air valve not opened will default to 0 and will not be included in the above comparison.

[0095] Then, the compressor operating frequency is controlled according to the maximum regional temperature difference and the maximum regional humidity difference.

[0096] Furthermore, for each area to be adjusted, the valve opening of the air valve corresponding to the area to be adjusted is adjusted according to the corresponding area temperature difference and area humidity difference.

[0097] Specifically, when the regional temperature of the area to be adjusted with the air valve opened reaches the target regional temperature and its regional humidity also reaches the target regional humidity at the same time, the air valve is adjusted to the minimum air volume angle and maintained to maintain the stability of the regional temperature and regional humidity.

[0098] When the regional humidity of the area to be adjusted with the air valve opened reaches the target regional humidity first and its regional temperature reaches the target regional temperature later, the air valve is controlled to continue to open to lower the regional temperature, and the air box is opened simultaneously for humidification until the regional temperature reaches the target regional temperature and the regional humidity reaches the target regional humidity.

[0099] When the regional temperature of the area to be adjusted with the air valve opened reaches the target regional temperature first and its regional humidity reaches the target regional humidity later, the air valve is controlled to be closed for three minutes and opened for three minutes until the regional temperature reaches the target regional temperature and the regional humidity reaches the target regional humidity.

[0101] It should be noted that the ducted air conditioner corresponds to multiple areas to be adjusted, each area to be adjusted corresponds to an air box, and the air box is communicated with the area controller in the ducted air conditioner.

[0102] In this embodiment, the regional temperature and regional humidity transmitted by the air box in the area to be adjusted are received by the information receiving module 410, and the control module 420 controls the compressor operating frequency and / or the air valves corresponding to the multiple areas to be adjusted based on the regional temperature and regional humidity, so that the ambient temperature and humidity of each area to be adjusted reach the set temperature and set humidity respectively. The device collects the precise temperature and humidity of the multiple areas to be adjusted through the air boxes set in the multiple areas to be adjusted, and controls the compressor operating frequency and air valves according to the collected regional temperature and regional humidity to achieve the purpose of accurately adjusting the temperature and humidity of the multiple areas to be adjusted, overcoming the defects of the existing duct air conditioner that cannot accurately control the temperature of multiple areas and does not control the humidity, and realizes the precise control of the temperature and humidity of multiple areas, effectively improving the user experience.
