Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with one or more embodiments of the present specification. Rather, they are merely examples of apparatus and methods consistent with certain aspects of one or more embodiments of the specification, as detailed in the claims which follow.
It should be noted that: in other embodiments, the steps of the corresponding methods are not necessarily performed in the order shown and described herein. In some other embodiments, the method may include more or fewer steps than those described herein. Moreover, a single step described in this specification may be broken down into multiple steps for description in other embodiments; multiple steps described in this specification may be combined into a single step in other embodiments.
Fig. 1 is a schematic diagram of an air conditioning unit 100 according to an embodiment of the present application. Referring to fig. 1, an air conditioning unit 100 includes an outdoor unit 11 and a plurality of indoor units 12. The outdoor unit 11 may be disposed outdoors. Different internal machines 12 may be located in different areas of the room, such as different rooms of the room. Each indoor unit 12 can control the temperature, humidity, ventilation, etc. of the area in which it is located. The operating modes of the inner machine 12 include, but are not limited to, a cooling mode, a heating mode, a ventilation mode, and a dehumidification mode.
In some embodiments, the inner machine 12 includes a winddisk 122 and a floor heater 123. The outer unit 11 may be connected to the winddisk 122, the floor heating 123, and other components of the inner unit 12. The outdoor unit 11 can provide heat exchange medium with corresponding temperature for the inner unit 12 according to the working mode of the inner unit 12. After passing through the wind plate 122 or the floor heating 123 and other components, the heat exchange medium can exchange heat with indoor air to adjust the indoor temperature, and the functions of cooling, heating and the like of the air conditioning unit 100 are achieved. The application takes the heat exchange medium as water as an example for explanation. For example, when the inner unit 12 operates in the cooling mode, the outer unit 11 supplies cold water to the inner unit 12. The cold water provided by the outdoor unit 11 exchanges heat with indoor air through the wind disk 122 of the indoor unit 12, so as to achieve the purpose of reducing indoor temperature. For example, when the indoor unit 12 is operating in the heating mode, the outdoor unit 11 supplies hot water to the indoor unit 12. The hot water provided by the outdoor unit 11 exchanges heat with indoor air through the wind plate 122 or the floor heating 123 of the indoor unit 12, so as to raise indoor temperature.
In some embodiments, the operation of the inner unit 12 may be divided into an operation requiring cooperation of the outer unit 11 and an operation not requiring cooperation of the outer unit 11. The inner unit 12 needs the outer unit 11 to work cooperatively to indicate that the outer unit 11 needs to work cooperatively during the operation of the inner unit 12. For example, when the indoor unit 12 operates in one of a cooling mode, a heating mode, and a dehumidification mode, the indoor unit 12 needs the outdoor unit 11 to provide a heat transfer medium with a corresponding temperature to the indoor unit 12 for heat transfer, and then the indoor unit 12 operates in the cooling mode, the heating mode, and the dehumidification mode in cooperation with the outdoor unit 11. The inner unit 12 does not require the cooperation of the outer unit 11 to indicate that the outer unit 11 does not need to cooperate in the operation of the inner unit 12. For example, when the inner unit 12 operates in the ventilation mode, the inner unit 12 does not need the cooperation of the outer unit 11, and the operation mode of the outer unit 11 and whether the outer unit 11 operates have no influence on the operation of the inner unit 12, and the operation of the inner unit 12 in the ventilation mode does not need the cooperation of the outer unit 11.
In some embodiments, the operation modes of the outdoor unit 11 also include a heating mode and a cooling mode, corresponding to the operation modes of the indoor unit 12. The operation mode of the inner unit 12 needs to be matched with that of the outer unit 11. For example, when the internal unit 12 operates in the heating mode, the external unit 11 needs to correspondingly operate in the heating mode to provide hot water for the internal unit 12; when the inner unit 12 operates in the cooling mode or the dehumidification mode, the outer unit 11 needs to operate in the cooling mode to provide cold water to the inner unit 12. If a plurality of internal machines 12 are connected to the same external machine 11 and the work of the internal machines 12 requires the cooperation of the external machine 11 at the same time, the work modes of the internal machines 12 need to be matched with the work mode of the external machine 11. For example, the plurality of internal units 12 may all operate in a heating mode, and then the external unit 11 operates in the heating mode to provide hot water for the internal units 12 in a unified manner; for another example, the plurality of internal units 12 may partially operate in the cooling mode and partially operate in the dehumidification mode, and the external unit 11 operates in the cooling mode to uniformly supply cold water to the internal units 12.
In some embodiments, for multiple indoor units 12 operating in the heating mode or the cooling mode simultaneously, each indoor unit 12 may control the cooling temperature or the heating temperature of the area in which it is located. Taking the example that the plurality of internal units 12 simultaneously operate in the heating mode, the heating temperatures of the areas where the different internal units 12 are located may be different. The outdoor unit 11 provides hot water with a proper water temperature according to the heating temperature required by the plurality of indoor units 12, so that the plurality of indoor units 12 can exchange heat. For example, assuming that two indoor units 12 simultaneously operate in a heating mode, wherein the heating temperature required by one indoor unit 12 is 25 degrees celsius and the heating temperature required by the other indoor unit 12 is 29 degrees celsius, the outdoor unit 11 can provide hot water of 30 degrees celsius for the two indoor units 12 to exchange heat, and the heating temperature of the area where the indoor unit 12 is located is controlled by the indoor unit 12.
In some embodiments, the indoor unit 12 includes an indoor unit controller 121. The indoor unit 12 can be controlled by the indoor unit controller 121. The control of the internal machine 12 by the internal machine controller 121 may include, but is not limited to, on-off control, switching of operating modes, temperature setting, and wind speed adjustment of the internal machine 12. In some embodiments, the internal machine controller 121 includes a line controller.
In some embodiments, the outdoor unit 11 is communicatively coupled to the indoor unit controller 121. When the indoor unit 12 is controlled by the indoor unit controller 121, the outdoor unit 11 can be controlled in a linked manner. For example, after the user controls the internal unit 12 to start up through the internal unit controller 121, if the operation of the internal unit 12 is the operation requiring the cooperation of the external unit 11, the internal unit controller 121 may perform the linkage control on the external unit 11 to control the external unit 11 to start up. For another example, after the user sets the working mode of the inner unit 12 to the cooling mode through the inner unit controller 121, the inner unit controller 121 may communicate with the outer unit 11 to perform linkage control on the working mode of the outer unit 11, and adjust the working mode of the outer unit 11 to the cooling mode matched with the working mode of the inner unit 12. For another example, after the user switches the operating mode of the internal unit 12 to the heating mode through the internal unit controller 121, the internal unit controller 121 may communicate with the external unit 11 to perform linkage switching on the operating mode of the external unit 11, and adjust the operating mode of the external unit 11 to the heating mode matched with the operating mode of the internal unit 12, so that the external unit 11 provides hot water to the internal unit 12. For another example, after the user adjusts the refrigeration temperature of the internal unit 12 from 10 degrees celsius to 15 degrees celsius through the internal unit controller 121, the internal unit controller 121 may communicate with the external unit 11 to perform linkage control on the water supply temperature of the external unit 11, so that the refrigeration requirement is met and the energy waste is reduced.
In some embodiments, if the linkage control of the external unit 11 by the internal units 12 conflicts, for example, the operation mode of part of the internal units 12 is set to the heating mode, and the operation mode of part of the internal units 12 is set to the cooling mode, so that the conflict occurs when the linkage control is performed on the external unit 11, the external unit 11 or the internal unit controller 121 may alarm.
In some embodiments, in addition to the linkage control of the outer unit 11 through the inner unit controller 121, the outer unit 11 may be directly controlled through the inner unit controller 121. The control of the outdoor unit 11 directly by the indoor unit controller 121 includes, but is not limited to, directly setting a water supply temperature of the outdoor unit 11 by the indoor unit controller 121, switching operation modes of heating and cooling the outdoor unit 11, setting a cold wind prevention mode of the outdoor unit 11, setting the outdoor unit 11 in a mute mode, and setting a water temperature of the outdoor unit 11.
In some related technologies, if communication failure occurs between the indoor unit controllers 121 of some of the indoor units 12 and the outdoor unit 11 due to external interference, communication line damage, and the like, the indoor unit controllers 121 need to control the corresponding indoor units 12 to stop working, so as to avoid possible mismatching of working modes of the indoor units 12 and the outdoor unit 11 with the communication failure, which may cause failure of corresponding control functions of the indoor units 12 with the communication failure and reduction of user experience. For example, assume that the internal unit 12 with a communication failure operates in a heating mode. Since the internal unit 12 having a communication failure cannot communicate with the external unit 11, the external unit 11 cannot be controlled in an interlocking manner. In this case, if the other communication-normal internal units 12 control the external unit 11 to be in the cooling mode in a linkage manner, at this time, the external unit 11 provides cold water to the communication-failed internal unit 12, and the communication-failed internal unit 12 may not be able to heat through heat exchange, resulting in a failure of the heating function of the communication-failed internal unit 12. Especially, when the inner unit 12 includes parts such as the floor heating 123, cold water passing through the floor heating 123 can cause floor condensation, which causes bad experience for users, and therefore it is necessary to stop the work of the inner unit 12 in time when the working modes of the inner unit 12 and the outer unit 11 with communication failure are not matched. However, assuming that the indoor unit 12 with the communication failure with the outdoor unit 11 operates in the heating mode and the outdoor unit 11 also operates in the heating mode, the communication failure indoor unit 12 may actually continue to operate. And as soon as the communication fault occurs between the inner unit 12 and the outer unit 11 in the related art, the mode of stopping the inner unit 12 with the communication fault increases the times of forced stop of the inner unit 12, and when a user urgently needs to use an air conditioner but is not in time to maintain, the air conditioner cannot be used, so that the experience brought to the user is not good, and the improvement is needed.
Fig. 2 is a flowchart of an air conditioner control method according to an embodiment of the present application. The air conditioning control method of fig. 2 may be applied to the air conditioning unit 100 of fig. 1. In some embodiments, the air conditioner control method may be applied to the internal machine controller 121. In other embodiments, the control method may be applied to a main controller of the air conditioning unit 100. The present application will be described taking an example in which the air conditioner control method is applied to the internal unit controller 121.
Referring to fig. 2, the air conditioner control method includes steps S21 and S22.
In step S21, when the communication between the indoor unit 12 and the outdoor unit 11 of the air conditioning unit 100 fails, if the indoor unit 12 and the outdoor unit 11 work cooperatively, the temperature change of the environment where the indoor unit 12 is located is detected.
As can be seen from the above description, the communication failure between the inner unit 12 and the outer unit 11 is actually the communication failure between the inner unit controller 121 of the inner unit 12 and the outer unit 11. The indoor unit controller 121 may detect whether the corresponding indoor unit 12 and the outdoor unit 11 have a communication failure by a heartbeat signal with the outdoor unit 11. The principle of detecting communication failure by means of heartbeat signals is conventional in the related art, and the detailed description of the present application is omitted here. In the explanation of the control method in this application, if nothing else is stated, the inner unit 12 may refer to the inner unit 12 that has failed in communication with the outer unit 11, and will not be described below.
In some embodiments, after the internal unit controller 121 detects a communication failure between the internal unit 12 and the external unit 11, a communication failure alarm may be performed to remind a user. The manner of performing the communication failure alarm includes, but is not limited to, displaying the failure alarm through a display screen, and performing the alarm in the form of sound through an alarm. In the present embodiment, after the communication between the internal unit 12 and the external unit 11 fails, the internal unit controller 121 displays a communication failure alarm every preset time (for example, 5 seconds) through the display screen.
In some embodiments, as can be seen from the above description, if the operation of the inner unit 12 does not require the cooperation of the outer unit 11, the inner unit 12 does not need to communicate with the outer unit 11, and the current operation mode of the outer unit 11 and whether the outer unit 11 is operating do not affect the operation of the inner unit 12. Therefore, when the communication between the internal machine 12 and the external machine 11 fails, if the operation of the internal machine 12 in the current operation mode is a work that does not require cooperation of the external machine 11, the internal machine controller 121 may control the internal machine 12 to continue to operate in the current operation mode. For example, if the communication between the inner unit 12 and the outer unit 11 is failed, the current operating mode of the inner unit 12 is the ventilation mode, the inner unit 12 does not need to communicate with the outer unit 11 when performing the ventilation function, and whether the outer unit 11 operates or not and the current operating mode of the outer unit 11 have no influence on the ventilation function of the inner unit 12, so the inner unit controller 121 may control the inner unit 12 to continue to operate in the current ventilation mode.
In some embodiments, if the inner unit 12 fails to communicate with the outer unit 11 and the inner unit 12 needs to cooperate with the outer unit 11, the inner unit controller 121 may sense the temperature of the area where the inner unit 12 is located. The internal unit controller 121 may sense the temperature of the area where the internal unit 12 is located once every preset time period (e.g., every 1 minute), and determine the temperature change of the area where the internal unit 12 is located according to the temperature values sensed multiple times.
Step S22, determining whether the current working mode of the internal unit 12 matches the current working mode of the external unit 11 based on the temperature change and the current working mode of the internal unit 12, and if so, controlling the internal unit 12 to continue working in the current working mode.
In some embodiments, when the current operating mode of the internal unit 12 is the heating mode, if the temperature rise of the environment where the internal unit 12 is located exceeds the heating temperature rise threshold within the heating temperature rise time, it is determined that the current operating mode of the internal unit 12 matches the current operating mode of the external unit 11. If the heating temperature rise time is long, the rise temperature of the environment where the internal machine 12 is located does not exceed the heating temperature rise threshold; or within the heating and cooling time, the cooling temperature of the environment where the internal unit 12 is located is not lower than the heating and cooling threshold, and it is determined that the current working mode of the internal unit 12 is not matched with the current working mode of the external unit 11. The details will be described below.
In some embodiments, when the internal unit 12 operates in the heating mode, the external unit 11 may include three operation modes, i.e., a heating mode, a shutdown mode, and a cooling mode. When the outdoor unit 11 works in the heating mode, the outdoor unit 11 is matched with the working mode of the indoor unit 12, the outdoor unit 11 provides hot water for the indoor unit 12, and the temperature of the environment where the indoor unit 12 is located is increased; when the outdoor unit 11 is in the shutdown mode, the operation mode of the indoor unit 12 is not matched, the outdoor unit 11 does not supply water to the indoor unit 12, and the temperature change of the environment where the indoor unit 12 is located is small; when the outdoor unit 11 operates in the cooling mode, the outdoor unit 11 supplies cold water to the indoor unit 12, and the temperature of the environment where the indoor unit 12 is located is lowered, which is not matched with the operation mode of the indoor unit 12. Based on this:
the heating temperature increase threshold may be determined by: assuming that the current working mode of the internal unit 12 is matched with the current working mode of the external unit 11, after the internal unit 12 works in the heating mode for heating and warming for a long time, the temperature at which the environment of the internal unit 12 is at least increased is determined, and then the heating and warming threshold value is determined according to the temperature at which the environment of the internal unit 12 is at least increased.
In one embodiment, assuming that the indoor unit 12 and the outdoor unit 11 both operate in the heating mode, after the indoor unit 12 is started, the indoor unit 12 may increase the ambient temperature of the area by more than 1 degree celsius when operating in the heating mode for 30 minutes. The temperature of 1 degree centigrade can be used as a heating temperature rise threshold, and the time of 30 minutes can be used as a heating temperature rise time. The heating temperature-rise time and the heating temperature-rise threshold may be set according to the actual heating capacity of each indoor unit 12.
Based on the determined heating temperature-rise threshold and the determined heating temperature-rise time, in one embodiment, when the internal unit 12 is started, if the internal unit 12 is operating in the heating mode, and the internal unit controller 121 detects a communication failure between the internal unit 12 and the external unit 11 when the internal unit 12 is started. The internal machine controller 121 detects the temperature of the environment where the internal machine 12 is located once per minute within the heating temperature rise time period after the internal machine 12 is started and operates for 3 minutes to reach stability. If the heating temperature rise time is long, the rise temperature of the environment where the indoor unit 12 is located exceeds the heating temperature rise threshold, which indicates that the outdoor unit 11 works in the heating mode, and the working modes of the outdoor unit 11 and the indoor unit 12 are matched. The indoor unit controller 121 may control the indoor unit 12 to continue operating in the current operating mode. If the heating temperature rise time is long, the rise temperature of the environment where the internal unit 12 is located does not exceed the heating temperature rise threshold, which indicates that the external unit 11 may be in a shutdown state, and the working modes of the external unit 11 and the internal unit 12 are not matched. The internal unit controller 121 controls the internal unit 12 to turn off the internal unit 12 and alarm.
The heating and cooling threshold value can be determined as follows: assuming that the current operation mode of the outer unit 11 is a cooling mode, the outer unit 11 supplies cold water to the inner unit 12. After the indoor unit 12 works in the heating mode for a heating and cooling time, the temperature at which the environment of the indoor unit 12 is at least reduced is determined, and then the heating and cooling threshold value is determined according to the temperature at which the environment of the indoor unit 12 is at least reduced.
In some embodiments, assuming that the inner unit 12 operates in the heating mode and the outer unit 11 operates in the cooling mode, after the inner unit 12 is started, the inner unit 12 may operate in the heating mode for 5 minutes, so that the ambient temperature of the area where the inner unit 12 is located may be reduced by at least 2 ℃. The temperature of 2 ℃ can be used as a heating and cooling threshold, and the time of 5 minutes can be used as the heating and cooling time. The heating and cooling time and the heating and cooling threshold value may be set according to the actual conditions of each indoor unit 12.
Based on the determined heating and cooling threshold and the heating and cooling duration, in one embodiment, when the internal unit 12 is started, if the internal unit 12 operates in the heating mode, and the internal unit controller 121 detects a communication failure between the internal unit 12 and the external unit 11 when the internal unit 12 is started. The internal unit controller 121 detects the temperature of the environment where the internal unit 12 is located once per minute within the heating and cooling time period after the internal unit 12 is started and operates for 3 minutes to reach a stable state. If the reduced temperature of the environment where the internal machine 12 is located is not lower than the heating temperature-rise threshold value within the heating temperature-fall time, it indicates that the external machine 11 is operating in the cooling mode, the operating modes of the external machine 11 and the internal machine 12 are not matched, and the internal machine controller 121 may control the internal machine 12 to stop operating.
In some embodiments, when the inner unit 12 operates in a heating mode and the outer unit 11 operates in a cooling mode, the water temperature provided by the outer unit 11 is different, or the working components of the inner unit 12 are different (for example, some inner units 12 exchange heat through the wind disk 122 and some inner units 12 exchange heat through the floor heating 123), it may be possible that the inner units 12 are in different cooling speeds in the same working time duration in the environment. In order to improve the timeliness of detection when the current working mode of the indoor unit 12 is not matched with the current working mode of the outdoor unit 11, in some embodiments of the present application, the heating and cooling duration may include a first heating and cooling duration and a second heating and cooling duration, the heating and cooling threshold may include a first heating and cooling threshold and a second heating and cooling threshold, the first heating and cooling duration is greater than the second heating and cooling duration, and the first heating and cooling threshold is smaller than the second heating and cooling threshold; if the temperature of the environment where the internal machine 12 is located is not lower than the first heating and cooling threshold value within the first heating and cooling duration; or in the second heating and cooling time period, the reduced temperature of the environment where the internal unit 12 is located is not lower than the second heating and cooling threshold, and it may be determined that the reduced temperature of the environment where the internal unit 12 is located is not lower than the heating and cooling threshold in the heating and cooling time period. In this embodiment, the first heating and cooling time is 5 minutes, the second heating and cooling time is 2 minutes, the first heating and cooling threshold is 2 degrees celsius, and the second heating and cooling threshold is 3 degrees celsius. That is, the reduced temperature of the environment where the internal unit 12 is located is not lower than 2 degrees celsius within 5 minutes, or the reduced temperature of the environment where the internal unit 12 is located is not lower than 3 degrees celsius within 2 minutes, it can be determined that the current operating mode of the external unit 11 is not matched with the current operating mode of the internal unit 12. Therefore, when the temperature of the environment where the internal machine 12 is located is fast, the internal machine 12 can be turned off in time.
In some embodiments, the internal unit 12 operates in the heating mode, and it is determined that the current operating mode of the internal unit 12 matches the current operating mode of the external unit 11 by determining that the temperature rise of the environment in which the internal unit 12 is located exceeds the heating temperature rise threshold within the heating temperature rise time; and within the heating temperature rise time, judging that the rise temperature of the environment where the internal machine 12 is located does not exceed the heating temperature rise threshold; or within the heating and cooling time, the reduced temperature of the environment where the internal machine 12 is located is not lower than the heating and cooling threshold, so as to determine that the current working mode of the internal machine 12 is not matched with the current working mode of the external machine 11.
In some embodiments, when the current operating mode of the internal unit 12 is the cooling mode, if the cooling temperature of the environment where the internal unit 12 is located exceeds the cooling threshold within the cooling time period, it is determined that the current operating mode of the internal unit 12 matches the current operating mode of the external unit 11. Within the cooling time, the temperature of the environment where the internal machine 12 is located does not exceed the cooling threshold; or within the cooling and heating time, the temperature rise of the environment where the internal machine 12 is located is not lower than the cooling and heating threshold, and the current working mode of the internal machine 12 is determined to be not matched with the current working mode of the external machine 11. The refrigeration heating time length comprises a first refrigeration heating time length and a second refrigeration heating time length, the refrigeration heating threshold value comprises a first refrigeration heating threshold value and a second refrigeration heating threshold value, the first refrigeration heating time length is larger than the second refrigeration heating time length, and the first refrigeration heating threshold value is smaller than the second refrigeration heating threshold value. Within the first refrigeration heating-up duration, the heating-up temperature of the environment where the internal machine 12 is located is not lower than a first refrigeration heating-up threshold; or in the second refrigeration heating-up time, the rising temperature of the environment where the internal machine 12 is located is not lower than the second refrigeration heating-up threshold, and it is determined that in the refrigeration heating-up time, the falling temperature of the environment where the internal machine 12 is located is not lower than the refrigeration heating-up threshold. The principle of judging whether the current working mode of the inner unit 12 is matched or not matched with the current working mode of the outer unit 11 is similar to the principle of judging whether the inner unit 12 is working in the heating mode or not matched with the current working mode of the outer unit 11, and the details are not repeated here.
In some embodiments of the present application, in the air conditioner control method, when the inner unit 12 of the air conditioning unit 100 fails to communicate with the outer unit 11, if the inner unit 12 operates in the current operating mode to cooperate with the outer unit 11, the temperature change of the environment where the inner unit 12 is located is detected, and based on the temperature change and the current operating mode of the inner unit 12, when it is determined that the current operating mode of the inner unit 12 matches the current operating mode of the outer unit 11, the inner unit 12 may be controlled to continue to operate in the current operating mode. According to the air conditioner control method, when the communication between the inner unit 12 and the outer unit 11 fails, a user can still continue to use the air conditioner control method, and therefore the user experience can be improved.
In some embodiments, based on the air conditioner control method of the present application, when a communication failure occurs between a part of the inner units 12 of the air conditioning unit 100 and the outer unit 11, if the inner unit 12 with the communication failure needs to be used, the working mode of the outer unit 11 may be set through the inner unit controller 121 of the inner unit 12 with normal communication, so that the working mode of the outer unit 11 is matched with the working mode of the inner unit 12 with the communication failure, and thus, the inner unit 12 with the communication failure occurring with the outer unit 11 may work normally. For example, the indoor unit 12 with a communication failure needs to operate in a heating mode, but the outdoor unit 11 operates in a cooling mode. In this case, the operation mode of the external unit 11 can be switched from the cooling mode to the heating mode by performing the coordinated control of the external unit 11 by the internal unit controller 121 of the internal unit 12 which has normal communication. So, the working mode phase-match of the inner unit 12 of communication trouble and outer unit 11, the inner unit 12 of communication trouble can normally work, has avoided inner unit 12 and outer unit 11 communication trouble back, and the user does not have time to maintain the inner unit 12 of communication trouble, but the problem of unable use when the user needs to use the inner unit 12 of communication trouble, can improve user experience greatly and feel.
