[0046] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described clearly and completely below with reference to the drawings in the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present application.

[0047] The control method, control device and ducted air conditioner provided by the present application will be described below with reference to the drawings. Before the embodiments of the present application are described in detail, the whole application scenario will be described first. The control method, control device, electronic device and computer readable storage medium of the ducted air conditioner of the embodiments of the present application can be applied not only to the ducted air conditioner locally, but also to the cloud platform in the Internet field, or the cloud platform in other kinds of Internet field, or to third party devices. The third party devices can include mobile phones, tablet computers, notebook computers, vehicle-mounted computers and other smart terminals of various types.

[0048] The control method suitable for the ducted air conditioner will be described below as an example. It should be understood that the control method of the embodiments of the present application can also be applied to the cloud platform and the third party devices.

[0049] As shown in Figure 1 , the control method of the ducted air conditioner according to the first aspect of the present application comprises:

[0050] Step S1, during the operation of the ducted air conditioner in the cooling mode, a signal for controlling the ducted air conditioner to switch to a set working mode is received, a set cooling temperature of the ducted air conditioner in the cooling mode is obtained, and the ducted air conditioner is controlled to switch to the set working mode.

[0051] Step S2, after the ducted air conditioner switches to the set working mode, a preset working temperature of the ducted air conditioner in the set working mode and / or a current environment temperature are obtained.

[0052] Step S3, according to a comparison result of the preset working temperature and / or the current environment temperature and the set cooling temperature, a working state of the ducted air conditioner in the set working mode is adjusted.

[0053] According to the control method of the ducted air conditioner, when the user has other use requirements, for example, the user needs the ducted air conditioner to perform the dehumidification, fresh air, and the like, the user issues an instruction for controlling the ducted air conditioner to switch to another working mode, and the controller receives a signal for controlling the ducted air conditioner to switch to the set working mode. Then, the controller records a set cooling temperature of the ducted air conditioner in the cooling mode, and then controls the ducted air conditioner to switch to the set working mode.

[0054] After the ducted air conditioner switches to the set working mode, a preset working temperature of the ducted air conditioner in the set working mode is obtained, and / or a current environment temperature is obtained. Then, the controller further compares at least one of the preset working temperature and the current environment temperature with the set cooling temperature, and adjusts a working state of the ducted air conditioner in the set working mode according to a comparison result, so that the user obtains a more comfortable use experience.

[0055] In the related art, the ducted air conditioner is a short name of a hidden air conditioner, and can also be referred to as an air conditioner ducted air conditioner or a ducted air conditioner. The indoor unit of the air conditioner ducted air conditioner and a terminal (fan coil) of a central air conditioner are basically the same, and are in the form of a ceiling, which is different from the central air conditioner. In the use scene, the ducted air conditioner is used in a unit project with a small area, and the central air conditioner is used in a unit project with a large area. In the operation mode, the ducted air conditioner usually has one indoor unit corresponding to one outdoor unit, and the central air conditioner has one outdoor unit corresponding to several indoor units. In the control mode, the ducted air conditioner controls the indoor unit and the outdoor unit as a whole, and the central air conditioner can control the indoor unit and the outdoor unit separately.

[0056] Compared with central air conditioning, the control logic of the ducted air conditioner on the market is relatively simple. When the ducted air conditioner receives a user-issued control dehumidification or control fresh air instruction during the execution of the refrigeration mode, that is, when the user's refrigeration demand conflicts with the dehumidification or fresh air demand, the existing ducted air conditioner will directly interrupt the refrigeration mode and immediately switch to the dehumidification or fresh air mode, resulting in that the original refrigeration demand cannot be met, only the user's single dehumidification or fresh air demand is met, that is, the balance between the user's refrigeration demand and other demands cannot be considered at the same time, thereby resulting in poor user experience and poor comfort.

[0057] In order to solve the technical defects existing in the above-mentioned related technology, the present application provides a control method of a ducted air conditioner. When the ducted air conditioner needs to switch to other working modes during the operation of the refrigeration mode, that is, when the user's refrigeration demand conflicts with the dehumidification or fresh air demand, the controller will first record the original set refrigeration temperature of the ducted air conditioner (the set refrigeration temperature represents the user's required refrigeration demand), and record the preset working temperature and / or the current environment temperature in the set working mode after the ducted air conditioner enters the set working mode (the temperature value represents the actual refrigeration demand in the set working mode), and compare the preset working temperature and / or the current environment temperature with the set refrigeration temperature (that is, compare the actual refrigeration demand with the user's required refrigeration demand), and adjust the working state of the ducted air conditioner in the set working mode according to the comparison result, so that the actual refrigeration temperature in the set working mode can approach the set refrigeration temperature in the original refrigeration mode, thereby meeting the user's original refrigeration demand in the dehumidification or fresh air and other working modes, and considering the balance between the user's refrigeration demand and other demands such as dehumidification or fresh air.

[0058] In summary, according to the control method of the ducted air conditioner according to the embodiments of the present application, when the user's refrigeration demand conflicts with the dehumidification or fresh air demand, the working state of the ducted air conditioner in the set working mode is adjusted based on the original set refrigeration temperature, so that the user's original refrigeration demand can be met in the dehumidification or fresh air and other working modes, and the balance between the user's refrigeration demand and other demands is considered at the same time, thereby improving the user's experience and ensuring the user's comfort.

[0059] The specific embodiments of the control method of the ducted air conditioner when the set working mode is the dehumidification mode will be introduced first.

[0060] According to some embodiments of the present application, the set working mode includes the dehumidification mode, and the step of controlling the ducted air conditioner to switch to the set working mode specifically includes:

[0061] obtaining the current actual refrigeration temperature of the ducted air conditioner in the refrigeration mode;

[0062] According to the actual refrigeration temperature and the set refrigeration temperature, mode switching logic is generated, and the ducted air conditioner is controlled to switch to the dehumidification mode according to the mode switching logic.

[0063] In the embodiment, during the switching of the ducted air conditioner from the refrigeration mode to the dehumidification mode, according to the comparison result of the actual refrigeration temperature and the set refrigeration temperature, the ducted air conditioner has two premise states before the mode switching, one is a first premise state when the actual refrigeration temperature does not reach the set refrigeration temperature, and the other is a second premise state when the actual refrigeration temperature has reached the set refrigeration temperature.

[0064] It can be understood that in the first premise state, the ducted air conditioner has not met the refrigeration demand of the user, and in the second premise state, the ducted air conditioner has met the refrigeration demand of the user, and the above two premise states need to be adjusted to the second premise state before the mode switching, so as to meet the refrigeration demand of the user, and therefore the mode switching logic required to be executed by the ducted air conditioner when switching the mode is different in different premise states.

[0065] Further, the step of generating mode switching logic according to the actual refrigeration temperature and the set refrigeration temperature, and controlling the ducted air conditioner to switch to the dehumidification mode according to the mode switching logic, specifically comprises:

[0066] According to the actual refrigeration temperature reaching the set refrigeration temperature, the ducted air conditioner is directly controlled to enter the dehumidification mode;

[0067] According to the actual refrigeration temperature not reaching the set refrigeration temperature, a first temperature difference value between the indoor environment temperature and the set refrigeration temperature is obtained, and execution logic is generated according to the first temperature difference value, and the ducted air conditioner is controlled to switch to the dehumidification mode according to the execution logic.

[0068] In the embodiment, when the actual refrigeration temperature reaches the set refrigeration temperature, it is proved that the ducted air conditioner has met the refrigeration demand of the user at present, and therefore the ducted air conditioner can be directly controlled to enter the dehumidification mode.

[0069] When the actual refrigeration temperature does not reach the set refrigeration temperature, it is proved that the ducted air conditioner has not met the refrigeration demand of the user, and the controller further obtains a first temperature difference value between the indoor environment temperature and the set refrigeration temperature. It can be understood that when the first temperature difference value is small, the actual refrigeration demand of the ducted air conditioner and the refrigeration demand required by the user are small and can be ignored, and therefore the ducted air conditioner can also directly enter the dehumidification mode at this time; when the first temperature difference value is large, it is proved that the actual refrigeration demand of the ducted air conditioner and the refrigeration demand required by the user are large, and therefore the working parameters of the ducted air conditioner need to be adjusted before switching to the dehumidification mode.

[0070] For example, the step of generating execution logic according to the first temperature difference value, and controlling the ducted air conditioner to switch to the dehumidification mode according to the execution logic, specifically comprises:

[0071] According to the first temperature difference value is less than the first set temperature difference, the air duct machine is directly controlled to enter the dehumidification mode;

[0072] According to the first temperature difference value is greater than the first set temperature difference, the compressor gear and / or the fan gear of the air duct machine are controlled to be up-regulated until the first temperature difference value is less than the first set temperature difference, and then the air duct machine is controlled to enter the defrosting mode.

[0073] In this way, when the actual refrigeration demand of the air duct machine is greatly different from the refrigeration demand required by the user, the controller will control the compressor frequency and / or the fan frequency to be up-regulated, that is, the compressor gear and / or the fan gear are controlled to be up-regulated, so as to increase the actual refrigeration temperature of the air duct machine, and the air duct machine will not perform defrosting until the actual refrigeration temperature of the air duct machine rapidly reaches the set refrigeration temperature, so as to ensure that the refrigeration demand of the user can also be met in the dehumidification mode.

[0074] According to some embodiments of the present application, the preset working temperature includes a preset dehumidification temperature, and according to the comparison result of the preset working temperature and / or the current environmental temperature with the set refrigeration temperature, the step of adjusting the working state of the air duct machine in the set working mode specifically includes:

[0075] After the step of controlling the air duct machine to directly enter the dehumidification mode according to that the actual refrigeration temperature reaches the set refrigeration temperature, if it is determined that the preset initial temperature is greater than the set refrigeration temperature, the compressor gear and / or the fan gear of the air duct machine are controlled to be down-regulated in the dehumidification mode.

[0076] In the present embodiment, it can be understood that if the preset dehumidification temperature set by the user in the dehumidification mode is less than or equal to the original set refrigeration temperature, the air duct machine performs dehumidification according to the original dehumidification working parameter; if the preset dehumidification temperature set by the user is greater than the original set refrigeration temperature, the user may feel that the refrigeration temperature of the air duct machine is relatively cold, and therefore, in order to meet the use demand of the user, the controller will control the compressor frequency and / or the fan frequency of the air duct machine to be down-regulated, that is, the compressor gear and / or the fan gear are controlled to be down-regulated, so as to make the indoor environmental temperature rise, avoiding that the user feels cold.

[0077] According to some embodiments of the present application, the control method of the air duct machine further includes:

[0078] In the dehumidification mode, the indoor environmental humidity is acquired;

[0079] If it is determined that the indoor environmental humidity is higher than the set humidity, the air duct machine is controlled to perform dehumidification operation.

[0080] Further, if the indoor environmental humidity is lower than the set humidity, the compressor gear of the air duct machine is reduced to perform dehumidification work, so that the indoor environmental humidity can rise to the set humidity.

[0081] The following will continue to introduce a specific embodiment of the control method of the ducted air conditioner when the working mode is set to the fresh air mode.

[0082] According to some embodiments of the present application, the working mode includes the fresh air mode, the current environment temperature includes the indoor environment temperature and the outdoor environment temperature, and the step of adjusting the working state of the ducted air conditioner in the set working mode according to the preset working temperature and / or the comparison result of the current environment temperature and the set cooling temperature and the mode switching logic specifically includes:

[0083] Adjusting the working state of the ducted air conditioner in the fresh air mode according to the outdoor environment temperature, the set cooling temperature and the indoor environment temperature.

[0084] It can be understood that when switching to the fresh air mode, the ducted air conditioner will introduce outdoor air into the indoor environment, so the temperature of the outdoor air will affect the indoor environment temperature, and then to ensure that the indoor environment temperature is stable at the set cooling temperature, the controller will control and adjust the working parameters of the ducted air conditioner in the fresh air mode to eliminate the adverse effects caused by the inflow of outdoor air into the indoor environment.

[0085] Further, the step of adjusting the working state of the ducted air conditioner in the fresh air mode according to the outdoor environment temperature, the set cooling temperature and the indoor environment temperature specifically includes:

[0086] Determining that the outdoor environment temperature is less than or equal to the set cooling temperature, and then controlling the ducted air conditioner to normally run the fresh air mode according to the original parameters;

[0087] Determining that the outdoor environment temperature is greater than the set cooling temperature, then calculating a first temperature difference value between the indoor environment temperature and the set cooling temperature and a second temperature difference value between the outdoor environment temperature and the set cooling temperature, and adjusting the working parameters of the ducted air conditioner according to the ratio result of the second temperature difference value and the first temperature difference value.

[0088] In this embodiment, if the outdoor environment temperature is less than or equal to the set cooling temperature, the temperature of the fresh air introduced in the fresh air mode is lower than the set cooling temperature, so the fresh air has no adverse effect on the indoor environment temperature, and at this time the ducted air conditioner can normally run the fresh air mode according to the original parameters.

[0089] And if the outdoor environment temperature is greater than the set cooling temperature, that is, the temperature of the fresh air is higher than the set cooling temperature, at this time the fresh air may cause the indoor environment temperature to rise and deviate from the set cooling temperature.

[0090] Therefore, to ensure that the indoor environment temperature meets the cooling demand of the user, the controller further acquires a first temperature difference between the indoor environment temperature and the set cooling temperature, and a second temperature difference between the outdoor environment temperature and the set cooling temperature, and calculates a ratio between the first temperature difference and the second temperature difference. It can be understood that when the ratio is small, it proves that the outdoor introduced fresh air has little adverse effect on the indoor environment and can be ignored, so at this time the fresh air mode can continue to run according to the original parameters; when the ratio is large, it proves that the outdoor introduced fresh air has a large adverse effect on the indoor environment, so at this time the working parameters of the ducted air conditioner need to be adjusted before switching to the dehumidification mode.

[0091] For example, according to the ratio of the second temperature difference to the first temperature difference, the step of adjusting the working parameters of the ducted air conditioner specifically includes:

[0092] According to the ratio of the second temperature difference to the first temperature difference being greater than one, the compressor gear and / or the fan gear of the ducted air conditioner in the fresh air mode are adjusted upward;

[0093] According to the ratio of the second temperature difference to the first temperature difference being less than or equal to one, the ducted air conditioner runs in the fresh air mode according to the original parameters.

[0094] In this way, when the outdoor introduced fresh air has a large adverse effect on the indoor environment, the controller will control the compressor frequency and / or the fan frequency to rise, that is, the compressor gear and / or the fan gear are adjusted upward, so as to improve the actual cooling temperature of the ducted air conditioner, and then eliminate the adverse effect of the outdoor introduced fresh air on the indoor environment temperature, ensure the stability and comfort of the indoor environment temperature in the fresh air mode, and meet the cooling demand of the user.

[0095] Hereinafter, a specific embodiment of the control method of the ducted air conditioner of the present application will be described with reference to the accompanying drawings.

[0096] As shown in Figure 2 The ducted air conditioner can control the dehumidification and fresh air functions according to parameters in the cooling state. The cooling state is divided into two states: running to the user temperature parameter and not running to the user set parameter.

[0097] Under the running to the user set parameter, when the user switches the ducted air conditioner to the dehumidification mode, the temperature is adjusted. If the adjusted temperature (that is, the set dehumidification temperature) is less than or equal to the set cooling temperature, the dehumidification program is followed; if the adjusted temperature is greater than the set cooling temperature, the user may feel that the temperature of the ducted air conditioner is too cold, so the ducted air conditioner is downshifted for temperature adjustment, and the ducted air conditioner determines the indoor humidity setting. If the indoor humidity is greater than the set humidity, dehumidification is performed; if the indoor humidity is less than the set humidity, the air conditioner is downshifted for dehumidification work.

[0098] In the running to the user setting parameter, the user opens the fresh air mode, marks the indoor environment temperature as T0, sets the cooling temperature as T1, and marks the outdoor environment temperature as T2, and compares the three, if T2>T1, it shows that the outdoor environment temperature is hot, then the temperature difference comparison is carried out again, if the temperature difference between the outdoor environment temperature and the set cooling temperature divided by the temperature difference between the indoor environment temperature and the set cooling temperature is greater than 1, that is, (T2-T1) / (T0-T1)>1, the bad influence of the outdoor environment temperature on the indoor environment is greater, so the ducted air conditioner needs to use the ducted air conditioner to improve the power to compensate for the temperature when the outdoor fresh air enters the indoor environment.

[0099] In the case that the ducted air conditioner is not running to the user setting parameter, when the user switches the ducted air conditioner to the dehumidification mode, if T0-T1>2℃, it proves that the difference between the indoor environment temperature and the set cooling temperature is too large, the ducted air conditioner needs to quickly cool, that is, the ducted air conditioner increases the compressor gear and / or the fan gear to realize the quick cooling, so that the indoor environment temperature reaches or approaches the set cooling temperature, and then the dehumidification is run again; if T0-T1<2℃, it proves that the difference between the indoor environment temperature and the set cooling temperature is small, at this time, the dehumidification can be directly run.

[0100] In the case that the ducted air conditioner is not running to the user setting parameter, if the user opens the fresh air mode, compared with the above case of reaching the user setting temperature, because the temperature difference between the indoor environment temperature and the set cooling temperature is large, at this time, the compressor and / or the fan of the ducted air conditioner is increased by two gears to run.

[0101] The control device of the ducted air conditioner provided by the application is described below, and the control device of the ducted air conditioner described below can be correspondingly referred to the control method of the ducted air conditioner described above.

[0102] As shown in Figure 3 The control device of the ducted air conditioner according to the second aspect of the application comprises:

[0103] The first control module 110 is used for receiving the signal of controlling the ducted air conditioner to switch to the set working mode in the process of running the ducted air conditioner in the cooling mode, acquiring the set cooling temperature of the ducted air conditioner in the cooling mode, and controlling the ducted air conditioner to switch to the set working mode.

[0104] The acquisition module 120 is used for determining that the ducted air conditioner switches to the set working mode, acquiring the preset working temperature and / or the current environment temperature of the ducted air conditioner in the set working mode.
