[0048] Combination Figure 1 As shown, an embodiment of the present disclosure provides an air conditioner, comprising: an indoor unit 1 and an outdoor unit connected, an air supply duct and an air volume adjustment device 4. The air supply duct comprises a main duct 2 and a plurality of branch ducts 3 connected to one end of the main duct 2, the other end of the main duct 2 is connected to the indoor unit 1, the air outlet of each branch duct 3 is connected to the indoor air inlet, and the air cooled or heated by the indoor unit 1 can enter the air outlet of each branch duct 3 through the main duct 2 and the branch duct 3. The air volume adjustment device 4, the number of which is the same as the number of the branch ducts 3, is arranged in the corresponding branch ducts 3 or at the air outlet of the corresponding branch duct 3, and is used to control the opening to control whether the air cooled or heated at the air outlet of each branch duct 3 can enter the indoor air inlet.

[0049] Optionally, the air volume regulating device 3 includes an air volume regulating valve.

[0050] Optionally, the number of air volume regulating device control interfaces of the indoor computer board of the air conditioner is greater than the number of air volume regulating devices 4 .

[0051] Specifically, the number of the air volume regulating devices 4 can be 4, 5, or 6. The number of the air volume regulating devices 4 can be adjusted and set according to the number of rooms and the installation conditions of the air supply ducts, and will not be listed one by one here.

[0052] Optionally, when the air volume regulating device 4 is turned on, the air volume regulating device control interface is represented by a dial indicating turned on. When the air volume regulating device 4 is turned off, the air volume regulating device control interface is represented by a dial indicating turned off.

[0053] With the air conditioner provided by the embodiment of the present disclosure, an air volume regulating device 4 is provided in each branch duct 3 or at the air outlet of each branch duct 3, and the opening can be controlled to control whether the air after cooling or heating at the air outlet of each branch duct 3 can enter the indoor air inlet. By controlling the opening of the air volume regulating valve 4, the temperature and humidity of different rooms can be adjusted, so as to meet the air volume and temperature required by users in each room using the air conditioner, and the delivery air volume and room temperature reaching the room can be controlled in different areas.

[0054] Combination Figure 2 As shown, the embodiment of the present disclosure provides a method for controlling an air conditioner, comprising:

[0055] S201, the air conditioner adjusts the switch of the corresponding air volume adjustment device according to the indoor temperature of each room.

[0056] S202, the air conditioner adjusts the wind speed of the indoor unit and the target operating frequency of the compressor according to the closing number of the air volume adjustment device.

[0057] By adopting the method for controlling the air conditioner provided by the embodiment of the present disclosure, an air volume regulating device is arranged in each branch duct or at the air outlet of each branch duct, and the opening degree can be controlled to control whether the air after cooling or heating at the air outlet of each branch duct can enter the indoor air inlet. First, the switch of the corresponding air volume regulating device is adjusted according to the indoor temperature of each room, and then the wind speed of the indoor unit and the target operating frequency of the compressor are adjusted according to the number of closing of the air volume regulating device, so as to more accurately adjust the temperature and humidity of different rooms, so as to meet the room's required air volume and temperature of the user in each room using the air conditioner, and realize the partition control of the delivery air volume and room temperature to the room.

[0058] Optionally, the air conditioner adjusts the switch of the corresponding air volume regulating device according to the indoor temperature of each room, including: when the indoor temperature of the i-th room is equal to the set temperature of the i-th room, the air conditioner controls the corresponding air volume regulating device to be turned off to close the indoor air inlet. Or, when the indoor temperature of the i-th room is not equal to the set temperature of the i-th room, the air conditioner controls the corresponding air volume regulating device to be turned on to open the indoor air inlet. Wherein, i is a natural number, i=1, 2, ..., F n . F n is the number of air volume adjustment devices. Specifically, F n The value of can be 4, 5, or 6. n The value can be adjusted according to the number of rooms and the installation conditions of the air supply ducts, and will not be listed here one by one.

[0059] In this way, if the indoor temperature reaches the set temperature, the air volume regulating device is closed to close the indoor air inlet, so that the refrigerated or heated air in the air supply duct stops entering the room. If the indoor temperature does not reach the set temperature, the air volume regulating device is opened to open the indoor air inlet, so that the refrigerated or heated air in the air supply duct continues to enter the room, so that the indoor temperature reaches the set temperature. The temperature and humidity of different rooms can be adjusted more accurately to meet the room's required air volume and temperature of users in each room using the air conditioner, and the delivery air volume and room temperature reaching the room can be controlled in different areas.

[0060] Optionally, the air conditioner adjusts the wind speed of the indoor unit and the target operating frequency of the compressor according to the number of air volume regulating devices closed, including: when the number of air volume regulating devices closed is less than the total number of air volume regulating valves, the air conditioner adjusts the wind speed of the indoor unit and the target operating frequency of the compressor according to the number of air volume regulating devices closed, and / or the air volume of the indoor unit, and / or the current operating frequency of the compressor, and / or the total number of air volume regulating devices. When the number of air volume regulating devices closed is equal to the total number of air volume regulating valves, the air conditioner adjusts the wind speed of the indoor unit and the target operating frequency of the compressor according to the house heating condition and air volume leakage condition.

[0061] In this way, if the air volume regulating devices are not all closed, the wind speed of the indoor unit and the target operating frequency of the compressor are adjusted according to the number of closed air volume regulating devices, and / or the air volume of the indoor unit, and / or the current operating frequency of the compressor, and / or the total number of air volume regulating devices. If the air volume regulating devices are all closed, it is not necessary to adjust the wind speed of the indoor unit and the target operating frequency of the compressor according to the operating parameters of the air conditioner, but only to adjust the wind speed of the indoor unit and the target operating frequency of the compressor according to the heating condition of the house and the air volume leakage condition.

[0062] Optionally, the air conditioner adjusts the wind speed of the indoor unit and the target operating frequency of the compressor according to the number of closed air volume regulating devices, and / or the air volume of the indoor unit, and / or the current operating frequency of the compressor, and / or the total number of air volume regulating devices, including: the air conditioner adjusts the wind speed of the indoor unit according to the number of closed air volume regulating devices, the air volume of the indoor unit and the total number of air volume regulating devices. The air conditioner adjusts the target operating frequency of the compressor according to the number of closed air volume regulating devices, the current operating frequency of the compressor, the total number of air volume regulating devices and the correction factor.

[0063] In this way, if the air volume regulating devices are not all closed, the wind speed of the indoor unit is adjusted according to the number of closed air volume regulating devices, the air volume of the indoor unit and the total number of air volume regulating devices, and the target operating frequency of the compressor is adjusted according to the number of closed air volume regulating devices, the current operating frequency of the compressor, the total number of air volume regulating devices and the correction factor. This is conducive to more accurately adjusting the temperature and humidity of different rooms, thereby meeting the room air volume and temperature requirements of users in each room using the air conditioner, and realizing zone control of the delivery air volume and room temperature to the room.

[0064] Optionally, the air conditioner adjusts the wind speed of the indoor unit according to the number of closed wind volume adjustment devices, the wind volume of the indoor unit and the total number of wind volume adjustment devices, including: the air conditioner adjusts v=L c *(F n -F n0 ) / F n Among them, v is the wind speed of the indoor unit, L c is the air volume of the indoor unit, F n is the total number of air volume adjustment devices, F n0 The closing quantity of the air volume control device.

[0065] In this way, if the air volume regulating devices are not all closed, the wind speed of the indoor unit can be adjusted according to the number of closed air volume regulating devices, the air volume of the indoor unit and the total number of air volume regulating devices. This is conducive to more accurate adjustment of the temperature and humidity in different rooms, thereby meeting the required air volume and temperature of the rooms by users in each room using the air conditioner, and realizing zone control of the delivery air volume and room temperature reaching the room.

[0066] Optionally, according to the number of closed air volume regulating devices, the current operating frequency of the compressor, the total number of air volume regulating devices and the correction factor, adjusting the target operating frequency of the compressor includes: adjusting the air conditioner P c =P c0 *(F n -F n0 ) / F n *Xi. Among them, P c is the target operating frequency of the compressor, P c0 is the current operating frequency of the compressor, F n is the total number of air volume adjustment devices, F n0 is the closing quantity of the air volume regulating device, and Xi is the correction coefficient.

[0067] In this way, if the air volume regulating devices are not all closed, the target operating frequency of the compressor is adjusted according to the number of closed air volume regulating devices, the current operating frequency of the compressor, the total number of air volume regulating devices and the correction factor. This is conducive to more accurate adjustment of the temperature and humidity of different rooms, thereby meeting the required air volume and temperature of the rooms of users in each room using the air conditioner, and realizing zone control of the delivery air volume and room temperature to the room.

[0068] Optionally, the correction coefficient is associated with the current operating frequency of the compressor.

[0069] Specifically, the correction coefficient is associated with the current operating frequency of the compressor, including: when the current operating frequency of the compressor is in the first frequency interval, the air conditioner determines the correction coefficient to be the first coefficient value. Or, when the current operating frequency of the compressor is in the second frequency interval, the air conditioner determines the correction coefficient to be the second coefficient value. Or, when the current operating frequency of the compressor is in the third frequency interval, the air conditioner determines the correction coefficient to be the third coefficient value. Wherein, the first frequency interval is smaller than the second frequency interval, the second frequency interval is smaller than the third frequency interval, the second coefficient value is smaller than the third coefficient value, and the third coefficient value is smaller than the first coefficient value.

[0070] More specifically, the value range of the first frequency interval is [20 Hz, 30 Hz], the value range of the second frequency interval is [50 Hz, 60 Hz], and the value range of the third frequency interval is [80 Hz, 90 Hz]. The value of the first coefficient value may be 1.3, the value of the second coefficient value may be 0.7, and the value of the third coefficient value may be 1.2.

[0071] In this way, the correction coefficient and the operating frequency of the compressor are nonlinearly correlated, and the coefficient value of the correction coefficient is different in different frequency intervals. The coefficient value of the correction coefficient corresponding to the medium-sized second frequency interval is small, and the coefficient value of the correction coefficient corresponding to the smaller first frequency interval and the larger third frequency interval is large. In this way, it is helpful to more accurately determine the correction coefficient according to the current operating frequency of the compressor, so as to more accurately adjust the target operating frequency of the compressor according to the number of closed air volume regulating devices, the current operating frequency of the compressor, the total number of air volume regulating devices and the correction coefficient.

[0072] Specifically, the correction coefficient is associated with the current operating frequency of the compressor, including: when the current operating frequency of the compressor is in the fourth frequency interval, the air conditioner determines the correction coefficient to be the fourth coefficient value. Or, when the current operating frequency of the compressor is not in the fourth frequency interval, the air conditioner determines the correction coefficient to be the fifth coefficient value. Wherein, the fourth coefficient value is less than the fifth coefficient value.

[0073] In this way, the correction coefficient and the operating frequency of the compressor are nonlinearly correlated, and the coefficient value of the correction coefficient is different in different frequency intervals. The coefficient value of the correction coefficient corresponding to the fourth frequency interval is the smallest, which is the fifth coefficient value, and the correction coefficients corresponding to the frequency intervals other than the fourth frequency interval are all greater than the fifth coefficient value. In this way, it is helpful to more accurately determine the correction coefficient according to the current operating frequency of the compressor, so as to more accurately adjust the target operating frequency of the compressor according to the number of closed air volume regulating devices, the current operating frequency of the compressor, the total number of air volume regulating devices and the correction coefficient.

[0074] Optionally, the air conditioner adjusts the wind speed of the indoor unit and the target operating frequency of the compressor according to the house heating condition and the air volume leakage condition, including:

[0075] When the house insulation condition is poor and the air volume leakage condition is air volume leakage, the air conditioner adjusts the wind speed of the indoor unit to the lowest speed gear, and the operating frequency of the compressor is the frequency value corresponding to the lowest speed gear. Or,

[0076] When the house is well heated and the air volume leakage is no air volume leakage, the air conditioner adjusts the wind speed of the indoor unit to the lowest speed gear and the operating frequency of the compressor to the frequency value corresponding to the lowest speed gear. The air conditioner turns off the indoor unit and the compressor according to the indoor static pressure.

[0077] In this way, if all the air volume regulating devices are closed, and the house is poorly insulated and there is air leakage, the wind speed gear of the indoor unit needs to be maintained at the lowest speed gear, and the operating frequency of the compressor needs to be maintained at the frequency value corresponding to the lowest speed gear, so as to continue to supplement the cold leakage of the user's house. If all the air volume regulating devices are closed, and the house is well insulated and there is no air volume leakage, first maintain the wind speed gear of the indoor unit at the lowest speed gear, maintain the operating frequency of the compressor at the frequency value corresponding to the lowest speed gear, and then shut down the indoor unit and compressor according to the indoor static pressure. In this way, after all the air volume regulating valves are closed, it is beneficial to better meet the cooling or heating needs of indoor users and improve user experience.

[0078] Specifically, the air conditioner turns off the indoor unit and the compressor according to the indoor static pressure, including: when the rising value of the indoor static pressure is greater than the set pressure value, the air conditioner turns off the indoor unit and the compressor. Or, when the rising value of the indoor static pressure is less than or equal to the set pressure value, the air conditioner maintains the wind speed gear of the indoor unit at the lowest speed gear and the operating frequency of the compressor at the frequency value corresponding to the lowest speed gear. More specifically, the set pressure value can be 20Pa.

[0079] In this way, if the indoor static pressure is too high and greater than the set pressure value, continuing to run the air conditioner will increase the static pressure, causing discomfort to the user. At this time, the indoor unit and compressor need to be turned off. If the indoor static pressure is small and less than or equal to the set pressure value, the current operating state of the air conditioner can still be maintained. This helps to better meet the cooling or heating needs of indoor users and improve user experience.

[0080] Combination Figure 3 As shown, the embodiment of the present disclosure provides another method for controlling an air conditioner, comprising:

[0081] S301, the air conditioner adjusts the switch of the corresponding air volume adjustment device according to the indoor temperature of each room.

[0082] S302, when the number of closed air volume regulating devices is less than the total number of air volume regulating valves, the air conditioner adjusts the wind speed of the indoor unit and the target operating frequency of the compressor according to the number of closed air volume regulating devices, and / or the air volume of the indoor unit, and / or the current operating frequency of the compressor, and / or the total number of air volume regulating devices.

[0083] S303, when the number of closed air volume regulating devices is equal to the total number of air volume regulating valves, the air conditioner adjusts the wind speed of the indoor unit and the target operating frequency of the compressor according to the house heating condition and air volume leakage condition.

[0084] According to the method for controlling the air conditioner provided by the embodiment of the present disclosure, an air volume regulating device is arranged in each branch pipe or at the air outlet of each branch pipe, and the opening can be controlled to adjust to control whether the air after cooling or heating at the air outlet of each branch pipe can enter the indoor air inlet. First, the switch of the corresponding air volume regulating device is adjusted according to the indoor temperature of each room. If the air volume regulating device is not completely closed, the wind speed of the indoor unit and the target operating frequency of the compressor are adjusted according to the number of closed air volume regulating devices, and / or the air volume of the indoor unit, and / or the current operating frequency of the compressor, and / or the total number of air volume regulating devices. If the air volume regulating devices are all closed, it is not necessary to adjust the wind speed of the indoor unit and the target operating frequency of the compressor according to the operating parameters of the air conditioner, and it is only necessary to adjust the wind speed of the indoor unit and the target operating frequency of the compressor according to the heating condition of the house and the air volume leakage condition. In this way, the temperature and humidity of different rooms can be adjusted more accurately, so as to meet the required air volume and temperature of the room by the users in each room using the air conditioner, and the delivery air volume and room temperature reaching the room can be controlled in zones.

[0085] Combination Figure 4 As shown, the embodiment of the present disclosure provides another method for controlling an air conditioner, comprising:

[0086] S401, the air conditioner adjusts the switch of the corresponding air volume adjustment device according to the indoor temperature of each room.

[0087] S402, when the number of closed air volume regulating devices is less than the total number of air volume regulating valves, the air conditioner determines the number of closed air volume regulating devices, and / or the air volume of the indoor unit, and / or the current operating frequency of the compressor, and / or the total number of air volume regulating devices.

[0088] S403, the air conditioner adjusts the wind speed of the indoor unit according to the number of closed wind volume adjustment devices, the wind volume of the indoor unit and the total number of wind volume adjustment devices.

[0089] S404, the air conditioner adjusts the target operating frequency of the compressor according to the number of closed air volume regulating devices, the current operating frequency of the compressor, the total number of air volume regulating devices and the correction coefficient.

[0090] S405, when the number of closed air volume regulating devices is equal to the total number of air volume regulating valves, the air conditioner determines the room heating condition and air volume leakage condition.

[0091] S406, when the room heating condition is poor and the air volume leakage condition is air volume leakage, the air conditioner adjusts the wind speed of the indoor unit to the lowest speed gear and the operating frequency of the compressor to the frequency value corresponding to the lowest speed gear. Or,

[0092] S407, when the room heating condition is good and the air volume leakage condition is no air volume leakage, the air conditioner adjusts the wind speed of the indoor unit to the lowest speed gear and the operating frequency of the compressor to the frequency value corresponding to the lowest speed gear.

[0093] S408, the air conditioner turns off the indoor unit and the compressor according to the indoor static pressure.

[0094] According to the method for controlling the air conditioner provided by the embodiment of the present disclosure, an air volume regulating device is arranged in each branch pipe or at the air outlet of each branch pipe, and the opening can be controlled to adjust the opening to control whether the air after cooling or heating at the air outlet of each branch pipe can enter the indoor air inlet. First, the switch of the corresponding air volume regulating device is adjusted according to the indoor temperature of each room. If the air volume regulating device is not completely closed, the wind speed of the indoor unit is adjusted according to the number of closed air volume regulating devices, the air volume of the indoor unit and the total number of air volume regulating devices, and the target operating frequency of the compressor is adjusted according to the number of closed air volume regulating devices, the current operating frequency of the compressor, the total number of air volume regulating devices and the correction coefficient. It is conducive to more accurately adjusting the temperature and humidity of different rooms, so as to meet the required air volume and temperature of the room for users in each room using the air conditioner, and realize the zone control of the delivery air volume and room temperature to the room. If the air volume regulating devices are all closed, and the house is poorly warmed and there is air volume leakage, the gear of the wind speed of the indoor unit needs to maintain the lowest speed gear, and the operating frequency of the compressor needs to maintain the frequency value corresponding to the lowest speed gear, so as to continue to supplement the cold leakage of the user's house. If all the air volume regulating devices are closed, and the house is well-insulated and there is no air volume leakage, the indoor unit's wind speed gear is maintained at the lowest speed gear, and the compressor's operating frequency is maintained at the frequency value corresponding to the lowest speed gear, and then the indoor unit and compressor are turned off according to the indoor static pressure. In this way, after all the air volume regulating valves are closed, it is helpful to better meet the cooling or heating needs of indoor users and improve the user experience. In this way, it is helpful to more accurately adjust the temperature and humidity of different rooms, thereby meeting the room's required air volume and temperature for users in each room using the air conditioner, and realizing zone control of the delivery air volume and room temperature to the room.

[0096] By using the device 200 for controlling the air conditioner provided by the embodiment of the present disclosure, an air volume regulating device is arranged in each branch duct or at the air outlet of each branch duct, and the opening can be controlled to control whether the air after cooling or heating at the air outlet of each branch duct can enter the indoor air inlet. First, the switch of the corresponding air volume regulating device is adjusted according to the indoor temperature of each room, and then the wind speed of the indoor unit and the target operating frequency of the compressor are adjusted according to the number of closing of the air volume regulating device, so as to more accurately adjust the temperature and humidity of different rooms, so as to meet the room's required air volume and temperature of the user in each room using the air conditioner, and realize the partition control of the delivery air volume and room temperature to the room.
