[0046] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] The control method, control device and duct machine of the air duct machine proposed in the present invention are described below with reference to the accompanying drawings. Among them, before the embodiment of the present invention is described in detail, the entire application scenario is described first. The control method, control device, electronic device and computer-readable storage medium of the air duct machine of the embodiment of the present invention can be applied to the air duct machine locally, and can also be applied to the cloud platform in the Internet field, or other types of cloud platforms in the Internet field, or can also be applied to third-party devices. Among them, the third-party device may include many different types such as mobile phones, tablet computers, notebooks, car computers and other smart terminals.

[0048] The following description only takes the control method applicable to the duct machine as an example. It should be understood that the control method of the embodiment of the present invention can also be applied to the cloud platform and third-party equipment.

[0049] like Figure 1 As shown, a control method for a duct machine according to a first embodiment of the present invention includes:

[0050] Step S1, when the ducted air conditioner is running in the cooling mode, a signal for controlling the ducted air conditioner to switch to the set working mode is received, the 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, determining that the ducted air conditioner is switched to a set working mode, and obtaining a preset working temperature and / or a current ambient temperature of the ducted air conditioner in the set working mode;

[0052] Step S3, adjusting the working state of the duct air conditioner in the set working mode according to the comparison result between the preset working temperature and / or the current ambient temperature and the set cooling temperature.

[0053] According to the control method of the duct air conditioner according to an embodiment of the present invention, its specific working process is as follows: when the duct air conditioner is running in the cooling mode, when the user has other usage requirements, for example, when the user needs the duct air conditioner to perform dehumidification, fresh air and other functions, the user issues an instruction to control the duct air conditioner to switch to other working modes. At this time, the controller receives a signal to control the duct air conditioner to switch to the set working mode, and the controller records the set cooling temperature of the duct air conditioner in the cooling mode, and then controls the duct air conditioner to switch to the set working mode.

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

[0055] In the relevant technology, duct unit is the abbreviation of hidden air conditioner, and it can also be called air conditioner duct unit or duct air conditioner. The indoor unit of air conditioner duct unit is basically the same as a terminal of central air conditioner (fan coil), and both are in the form of suspended ceiling, which is different from central air conditioner. In terms of usage scenarios, duct unit is used in unit projects with relatively small area; central air conditioner is used in unit projects with relatively large area. In terms of operation mode, duct unit usually has one indoor unit corresponding to one outdoor unit; whether it is a water system or a fluorine system, the central air conditioner has one outdoor unit with several indoor units. In terms of control mode, duct unit controls indoor and outdoor units as a whole; central air conditioner can control indoor and outdoor units separately.

[0056] Compared with central air conditioners, the control logic of the current duct units on the market is relatively simple. When the duct unit receives instructions from the user to control dehumidification or fresh air during the execution of the cooling mode, that is, when the user's cooling demand conflicts with the dehumidification or fresh air demand, the existing duct unit will directly interrupt the cooling mode and immediately switch to the dehumidification or fresh air mode, resulting in the original cooling demand cannot be met, and only the user's single dehumidification or fresh air demand is met, that is, it is impossible to take into account the balance between the user's cooling demand and other demands at the same time, which in turn leads to poor user experience and poor comfort.

[0057] In order to solve the technical defects existing in the above-mentioned related technologies, the present invention proposes a control method for a duct air conditioner. When the duct air conditioner needs to switch to other working modes during the operation of the cooling mode, that is, when the user's cooling demand conflicts with the demand for dehumidification or fresh air, the controller will first record the original set cooling temperature of the duct air conditioner (the above-mentioned set cooling temperature represents the cooling demand required by the user), and after controlling the duct air conditioner to enter the set working mode, record the preset working temperature and / or the current ambient temperature in the set working mode (the above-mentioned temperature value represents the actual cooling demand in the set working mode), and compare the preset working temperature and / or the current ambient temperature with the set cooling temperature (that is, compare the actual cooling demand with the cooling demand required by the user), and adjust the working state of the duct air conditioner in the set working mode according to the comparison result, so that the actual cooling temperature in the set working mode can be close to the set cooling temperature in the original cooling mode, and then meet the user's original cooling demand in other working modes such as dehumidification or fresh air, while taking into account the user's cooling demand and other demands such as dehumidification or fresh air.

[0058] In summary, according to the control method of the duct air conditioner in an embodiment of the present invention, when the user's cooling demand conflicts with the demand for dehumidification or fresh air, the working state of the duct air conditioner in the set working mode is adjusted based on the original set cooling temperature, thereby meeting the user's original cooling demand in other working modes such as dehumidification or fresh air, while taking into account the balance between the user's cooling demand and other demands, thereby improving the user's usage experience and ensuring the user's comfort.

[0059] The following will first introduce a specific embodiment of the control method of the duct air conditioner when the working mode is set to the dehumidification mode.

[0060] According to some embodiments of the present invention, if the setting working mode includes a dehumidification mode, the step of controlling the duct air conditioner to switch to the setting working mode specifically includes:

[0061] Get the actual cooling temperature of the duct unit in cooling mode.

[0062] The mode switching logic is generated according to the actual cooling temperature and the set cooling temperature, and the duct unit is controlled to switch to the dehumidification mode according to the mode switching logic.

[0063] In this embodiment, during the process of the duct unit switching from cooling mode to dehumidification mode, based on the comparison result between the actual cooling temperature and the set cooling temperature, the duct unit has two premise states before the mode switching, one is the first premise state when the actual cooling temperature has not reached the set cooling temperature, and the other is the second premise state when the actual cooling temperature has reached the set cooling temperature.

[0064] It can be understood that in the first premise state, the duct machine has not yet met the user's cooling needs, while in the second premise state, the duct machine has met the user's cooling needs, and the above two premise states need to be adjusted to the second premise state before switching modes to meet the user's cooling needs. Therefore, in different premise states, the mode switching logic that the duct machine needs to execute when switching modes is also different.

[0065] Further, the step of generating a mode switching logic according to the actual cooling temperature and the set cooling temperature, and controlling the duct air conditioner to switch to the dehumidification mode according to the mode switching logic specifically includes:

[0066] When the actual cooling temperature reaches the set cooling temperature, the duct unit is controlled to directly enter the dehumidification mode;

[0067] If the actual cooling temperature does not reach the set cooling temperature, a first temperature difference between the indoor ambient temperature and the set cooling temperature is obtained, and an execution logic is generated according to the first temperature difference, and the duct unit is controlled to switch to a dehumidification mode according to the execution logic.

[0068] In this embodiment, when the actual cooling temperature reaches the set cooling temperature, it is proved that the duct air conditioner currently meets the cooling demand of the user, so the duct air conditioner can be directly controlled to enter the dehumidification mode.

[0069] When the actual cooling temperature does not reach the set cooling temperature, it proves that the duct unit does not meet the user's cooling needs. The controller further obtains the first temperature difference between the indoor ambient temperature and the set cooling temperature. It can be understood that when the first temperature difference is small, the actual cooling demand of the duct unit is slightly different from the cooling demand required by the user and can be ignored. Therefore, the dehumidification mode can be directly entered at this time; when the first temperature difference is large, it proves that the actual cooling demand of the duct unit is significantly different from the cooling demand required by the user. Therefore, the working parameters of the duct unit need to be adjusted before switching to the dehumidification mode.

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

[0071] If the first temperature difference is less than the first set temperature difference, the duct unit is controlled to directly enter the dehumidification mode;

[0072] According to the first temperature difference being greater than the first set temperature difference, the compressor gear and / or the fan gear of the duct unit are controlled to be increased, until the first temperature difference is less than the first set temperature difference, the duct unit is controlled to enter the defrost mode.

[0073] In this way, when the actual cooling demand of the duct air conditioner is significantly different from the cooling demand required by the user, the controller will control the compressor frequency and / or the fan frequency to increase, that is, control the compressor gear and / or the fan gear to increase, thereby increasing the actual cooling temperature of the duct air conditioner. The duct air conditioner will not perform defrost until the actual cooling temperature of the duct air conditioner quickly reaches the set cooling temperature, thereby ensuring that the user's cooling demand can also be met in the dehumidification mode.

[0074] According to some embodiments of the present invention, the preset working temperature includes a preset dehumidification temperature, and the step of adjusting the working state of the duct air conditioner in the set working mode according to the comparison result between the preset working temperature and / or the current ambient temperature and the set cooling temperature specifically includes:

[0075] After the step of controlling the duct unit to directly enter the dehumidification mode according to the actual refrigeration temperature reaching 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 fan gear of the duct unit is controlled to be lowered in the dehumidification mode.

[0076] In this 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 cooling temperature, the duct air conditioner performs dehumidification according to the original dehumidification working parameters; if the preset dehumidification temperature set by the user is greater than the original set cooling temperature, the user may feel that the cooling temperature of the duct air conditioner is colder. Therefore, in order to meet the user's usage needs, the controller will control the compressor frequency and / or fan frequency of the duct air conditioner to decrease, that is, control the compressor gear and / or fan gear to decrease, so that the indoor ambient temperature rises to avoid the user feeling cold.

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

[0078] In dehumidification mode, obtain the indoor ambient humidity;

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

[0080] Furthermore, if the indoor environmental humidity is lower than the set humidity, the compressor gear of the duct air conditioner is controlled to be lowered to perform dehumidification work, so that the indoor environmental humidity can return to the set humidity.

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

[0082] According to some embodiments of the present invention, the set working mode includes a fresh air mode, and the current ambient temperature includes an indoor ambient temperature and an outdoor ambient temperature. Then, according to the comparison result of the preset working temperature and / or the current ambient temperature with the set cooling temperature and the mode switching logic, the step of adjusting the working state of the duct air conditioner in the set working mode specifically includes:

[0083] Adjust the working status of the duct air conditioner in the fresh air mode according to the outdoor ambient temperature, the set cooling temperature and the indoor ambient temperature.

[0084] It can be understood that after switching to the fresh air mode, since the air duct machine will introduce outdoor air into the indoor environment in fresh air mode, the temperature of the outdoor air will affect the indoor ambient temperature. In order to ensure that the indoor ambient temperature is stable at the set cooling temperature, the controller will control and adjust the working parameters of the air duct machine in the fresh air mode to eliminate the adverse effects brought by the flow of outdoor air into the room.

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

[0086] If the outdoor ambient temperature is determined to be less than or equal to the set cooling temperature, the duct unit is controlled to operate normally in fresh air mode according to the original parameters;

[0087] If it is determined that the outdoor ambient temperature is greater than the set cooling temperature, the first temperature difference and the second temperature difference between the indoor ambient temperature and the outdoor ambient temperature and the set cooling temperature are calculated respectively, and the working parameters of the duct air conditioner are adjusted according to the ratio of the second temperature difference to the first temperature difference.

[0088] In this embodiment, if the outdoor ambient 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 ambient temperature. At this time, the duct unit can operate the fresh air mode normally according to the original parameters.

[0089] If the outdoor ambient temperature is greater than the set cooling temperature, that is, the fresh air temperature is higher than the set cooling temperature, the fresh air may cause the indoor ambient temperature to rise and deviate from the set cooling temperature.

[0090] Therefore, in order to ensure that the indoor ambient temperature meets the user's cooling needs, the controller further obtains a first temperature difference between the indoor ambient temperature and the set cooling temperature, as well as a second temperature difference between the outdoor ambient temperature and the set cooling temperature, and calculates the 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 adverse effects of the fresh air introduced from the outdoors on the indoor environment are small and can be ignored, so at this time, the fresh air mode can continue to operate according to the original parameters; when the ratio is large, it proves that the fresh air introduced from the outdoors has a greater adverse effect on the indoor environment, so at this time, the working parameters of the duct 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 air duct unit 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 duct air conditioner in the fresh air mode are controlled to be increased;

[0093] According to the ratio of the second temperature difference to the first temperature difference being less than or equal to one, the duct unit is controlled to operate normally in the fresh air mode according to the original parameters.

[0094] In this way, when the fresh air introduced from outdoor has a greater adverse effect on the indoor environment, the controller will control the compressor frequency and / or fan frequency to increase, that is, control the compressor gear and / or fan gear to increase, thereby increasing the actual cooling temperature of the duct unit, and then eliminating the adverse effect of the fresh air introduced from outdoor on the indoor ambient temperature, ensuring the stability and comfort of the indoor ambient temperature in the fresh air mode, and meeting the user's cooling needs.

[0095] A specific embodiment of the control method of the air duct machine of the present invention is described below with reference to the accompanying drawings.

[0096] like Figure 2 As shown in the figure, the ducted air conditioner can adjust the dehumidification and fresh air functions according to the parameters in the cooling state. In the cooling state, it is divided into two states: running to the user temperature parameters and not running to the user set parameters.

[0097] Among them, when running under the user-set parameters, the user switches the duct air conditioner to the dehumidification mode for temperature adjustment. 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 duct air conditioner is cold, so the duct air conditioner downgrades to adjust the temperature. At the same time, the duct 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 downgrades to perform dehumidification.

[0098] When running to the user-set parameters, the user turns on the fresh air mode, marks the indoor ambient temperature as T0, the set cooling temperature as T1, and the outdoor ambient temperature as T2, and compares the three. If T2>T1, it means that the outdoor ambient temperature is hotter. Then, the temperature difference is compared. If the temperature difference between the outdoor ambient temperature and the set cooling temperature divided by the temperature difference between the indoor ambient temperature and the set cooling temperature is greater than 1, that is, (T2-T1) / (T0-T1)>1, the outdoor ambient temperature has a greater adverse effect on the indoor environment. Therefore, when the outdoor fresh air enters the room, the duct machine needs to be used to increase the power for temperature compensation.

[0099] When the duct unit is not running to the user-set parameters, when the user switches the duct unit to the dehumidification mode, if T0-T1>2℃, it means that the difference between the indoor ambient temperature and the set cooling temperature is too large, and the duct unit needs to cool quickly, that is, the duct unit increases the compressor gear and / or fan gear to achieve rapid cooling, so that the indoor ambient temperature reaches or approaches the set cooling temperature, and then runs the dehumidification; if T0-T1<2℃, it means that the difference between the indoor ambient temperature and the set cooling temperature is small, and the dehumidification can be directly run at this time.

[0100] When the duct air conditioner is not running to the user-set parameters, if the user turns on the fresh air mode, compared with the above situation where the user-set temperature is reached, the temperature difference between the indoor ambient temperature and the set cooling temperature is larger. Therefore, the compressor and / or fan of the duct air conditioner will increase the power by two levels.

[0101] The control device of the duct machine provided by the present invention is described below. The control device of the duct machine described below and the control method of the duct machine described above can be referred to each other.

[0102] like Figure 3 As shown, a control device for a duct machine according to an embodiment of the second aspect of the present invention includes:

[0103] The first control module 110 is used to receive a signal for controlling the duct unit to switch to a set working mode when the duct unit is running in a cooling mode, obtain a set cooling temperature of the duct unit in the cooling mode, and control the duct unit to switch to the set working mode;

[0104] An acquisition module 120 is used to determine that the ducted air conditioner is switched to a set working mode, and to acquire a preset working temperature and / or a current ambient temperature of the ducted air conditioner in the set working mode;

[0105] The second control module 130 is used to adjust the working state of the duct air conditioner in the set working mode according to the comparison result between the preset working temperature and / or the current ambient temperature and the set cooling temperature.

[0106] The duct air conditioner according to the third aspect of the present invention includes the control device for the duct air conditioner described in the second aspect of the present invention.

[0107] According to the duct air conditioner and its control device of the embodiments of the present invention, when the user's cooling demand conflicts with the demand for dehumidification or fresh air, the working state of the duct air conditioner in the set working mode is adjusted based on the original set cooling temperature, so as to meet the user's original cooling demand in other working modes such as dehumidification or fresh air, while taking into account the balance between the user's cooling demand and other demands, thereby improving the user's usage experience and ensuring the user's usage comfort.
