Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
An embodiment of the present application provides a control method, referring to fig. 1, the method is applied to an air conditioning apparatus, and the method includes the following steps:
Step 101, if a first control instruction for indicating to exit the target working mode is received under the condition that the air conditioning equipment is currently operated in the target working mode, determining a suspension time for suspending the operation of the compressor of the air conditioning equipment.
The target working mode comprises a refrigeration multi-temperature working mode or a heating multi-temperature working mode.
In this embodiment of the present application, in order to ensure a user experience effect, when an air conditioner device is refrigerating or heating, cool air with different temperatures or hot air with different temperatures may be output at the same time, where an implementation manner may be to replace one evaporator with at least two evaporators in an indoor unit of the air conditioner device, and set a switch valve on the evaporator to control a refrigerant passing through each evaporator, so that air with different temperatures may be output after passing through each evaporator.
The first control instruction received by the air conditioning equipment may be obtained by pressing a physical key or a virtual key set on an indoor unit of the air conditioning equipment, or may be sent by a remote control device for controlling the air conditioning equipment, for example, a remote controller, or may be sent by a controller for controlling the air conditioning equipment, for example, an intelligent home central control device or an intelligent mobile terminal, etc. The refrigerating multi-temperature working mode refers to a refrigerating mode, the indoor unit can output cold air with at least two temperatures at the same time, and the heating multi-temperature working mode refers to a heating mode, wherein the indoor unit can output hot air with at least two temperatures at the same time. In the refrigerating multi-temperature working mode or the heating multi-temperature working mode, when outputting air with various temperatures, the output air with the lowest temperature is generally arranged at the uppermost layer of the space, so that the rise of hot air can be restrained, the temperature of the head of a user for cooling and warming the body is further ensured, and the use experience effect of the user is improved.
When the current air conditioning equipment operates in a target working mode of a refrigeration multi-temperature working mode or a heating multi-temperature working mode, after the air conditioning equipment receives a first control instruction sent by a user and used for indicating to exit the target working mode, the pause time for the compressor to pause working is determined. When the air conditioning equipment corresponds to different application scenes, the pause time of the corresponding compressor for pausing operation is different.
Step 102, determining a first target control parameter of at least one target switching valve.
The target switch valve is used for controlling the flow of the refrigerant flowing through the evaporator in the indoor unit of the air conditioning equipment connected with the target switch valve, the indoor unit comprises at least two evaporators, and the first target control parameter controls the corresponding target switch valve to be in a conducting state.
In this embodiment of the present application, the target switching valve may be a switching valve capable of realizing refrigerant flow control, and specifically may be an electromagnetic valve, for example, a normally open electromagnetic valve or a normally closed electromagnetic valve. The first target control parameter of the at least one target switching valve may be different from the actual control parameter of the current target switching valve. After the compressor is controlled to stop working and pause time, the air pressure at the two ends of the target switch valve can be ensured to be balanced. The first target control parameter is a parameter for controlling the opening or closing degree of the target opening-closing valve.
And 103, after the compressor is controlled to stop working and pause time, switching the working parameter of each target switching valve to be a corresponding first target control parameter.
In the embodiment of the application, after the compressor is controlled to stop working and pause time, the working parameter of each target switching valve is adjusted to be the first target control parameter, so that the working state of each target switching valve is controlled after the compressor is controlled to pause for a preset time in advance, and the possibility that the target switching valve is blocked due to the fact that the pressure is large when the compressor works is reduced.
Step 104, switching the air conditioning equipment to a reference working mode corresponding to the first control instruction.
In the embodiment of the application, after the air conditioning equipment responds to the first control instruction and exits from the target working mode, the air conditioning equipment is switched to the reference working mode, and the reference working mode is continuously used for providing services for users. The reference operating mode is different from the target operating mode.
The step 101 and the step 102 may be performed simultaneously, and the step 102 may also be performed before "determining a suspension duration for suspending the operation of the compressor of the air conditioner" in the step 101, and the specific execution sequence may be determined according to the actual application scenario.
In this embodiment, if a first control instruction for instructing to exit from a target working mode is received under the condition that the air conditioning equipment is currently operated in the target working mode, a suspension time for suspending the operation of the compressor of the air conditioning equipment is determined, and after the suspension time for stopping the operation of the compressor is controlled, a first target control parameter of at least one target switching valve is determined so as to switch the working parameter of each target switching valve to a corresponding first target control parameter. Therefore, under the condition that the air conditioning equipment currently operates in the target working mode, if a first control instruction for exiting the target working mode is received, the working parameters of at least one target switching valve are switched after the compressor is controlled to stop working and pause time, the problem that system faults are easily caused by controlling whether a refrigerant passes through the electromagnetic valve of the evaporator in the conventional multi-temperature air conditioning equipment is solved, a control method for reducing the system faults caused by controlling whether the refrigerant passes through the electromagnetic valve of the evaporator is easily blocked is provided, and the occurrence probability of the system faults is reduced.
Based on the foregoing embodiments, embodiments of the present application provide a control method, referring to fig. 2, the method is applied to an air conditioning apparatus, and the method includes the following steps:
Step 201, if a first control command is received under the condition that the air conditioning equipment is currently operated in the target working mode, determining a reference working mode to which the air conditioning equipment is to be switched based on the first control command.
The target working mode is different from the reference working mode, and comprises a refrigeration multi-temperature working mode or a heating multi-temperature working mode.
In the embodiment of the application, under the condition that the air conditioning equipment is currently operated in the target working mode, if the air conditioning equipment receives a first control instruction for indicating to exit the target working mode, the first control instruction is analyzed to determine a reference working mode to which the air conditioning equipment is to be switched. The first control instruction may be an instruction for simply indicating to exit the target working mode, that is, the specific reference working mode to which the air conditioning equipment is required to be switched is not indicated in the first control instruction, and at this time, the default reference working mode may be a working mode in which the air conditioning equipment is operated before the target working mode is operated. The first control command may also be used directly to indicate a reference operating mode to which the air conditioning apparatus needs to be switched.
Step 202, determining a suspension duration of stopping the operation of the compressor based on the target operation mode and the reference operation mode.
In the embodiment of the application, the air conditioning equipment analyzes the target working mode and the reference working mode to be switched to, and determines the pause time for controlling the compressor to pause.
Step 203, determining a first target control parameter of at least one target switching valve.
The target switch valve is used for controlling the flow of the refrigerant flowing through the evaporator in the indoor unit of the air conditioning equipment connected with the target switch valve, the indoor unit comprises at least two evaporators, and the first target control parameter controls the corresponding target switch valve to be in a conducting state.
In this embodiment, one evaporator is connected to one target on-off valve, and some evaporators may not be connected to the target on-off valve, i.e., the flow rate of the refrigerant flowing therethrough need not be controlled. The first target control parameter of the at least one target switch valve may be determined according to a current actual control parameter of the target switch valve, for example, the current actual state of the target switch valve is a closed state, that is, when the target switch valve currently controls the refrigerant not to pass through the evaporator, the corresponding first target control parameter is a control parameter for controlling the on state of the target switch valve, or when the current actual state of the target switch valve is a control parameter for controlling a part of the refrigerant to flow through the evaporator, the corresponding first target control parameter is a control parameter for controlling all on states of the target switch, or when the current actual state of the target switch valve is an on state, the first target control parameter is a control parameter corresponding to the current actual state.
And 204, after the compressor is controlled to stop working and pause time, switching the working parameter of each target switching valve to be a corresponding first target control parameter.
In the embodiment of the application, after the compressor is controlled to stop working and pause time, the working parameter of each target switching valve is set as the corresponding first target control parameter so as to control each target switching valve to reach the target switching state, thereby reducing the possibility that each target switching valve is blocked and reducing the possibility of system faults.
Step 205, switching the air conditioning equipment to a reference working mode corresponding to the first control instruction.
In the embodiment of the application, the working mode of the air conditioning equipment is switched to the reference working mode, so that the air conditioning equipment continues to work, and air conditioning service is provided for a user.
Step 203 may be performed before step 202 or step 201, or may be performed simultaneously with step 202 or step 201.
Based on the foregoing embodiments, in other embodiments of the present application, step 201 may be implemented by steps 201 a-201 b, or steps 201a, 201 c-201 d:
step 201a, if a first control instruction is received under the condition that the air conditioning equipment is currently operated in the target working mode, analyzing the first control instruction to obtain target indication information.
In the embodiment of the application, under the condition that the air conditioning equipment is currently operated in the target working mode, after receiving the first control instruction, the air conditioning equipment analyzes and analyzes the first control instruction to determine target indication information indicated by the first control instruction.
Step 201b, if the target indication information includes an indication operation mode to which the air conditioning equipment is to be switched, determining that the reference operation mode is the indication operation mode.
In this embodiment of the present application, if the first control instruction instructs the air conditioning apparatus to switch to the air supply mode, it is determined that the indicated operation mode included in the target instruction information is the air supply mode, and it is determined that the reference operation mode is the air supply mode.
Step 201c, if the target indication information does not include the indication working mode, determining a historical working mode corresponding to the air conditioning equipment before the air conditioning equipment is switched to the target working mode.
In the embodiment of the application, if only the air conditioning equipment is indicated to exit the target working mode in the target indication information, it is determined that the historical working mode corresponding to the air conditioning equipment is switched to before the air conditioning equipment is switched to the target working mode.
Step 201d, determining the reference operation mode as the history operation mode.
For example, after the air conditioning apparatus is switched from the air supply mode to the cooling multi-temperature operation mode or the heating multi-temperature operation mode, i.e., when the air conditioning apparatus is currently operated in the cooling multi-temperature operation mode or the heating multi-temperature operation mode, if the air conditioning apparatus receives a first control instruction for instructing the air conditioning apparatus to exit only the cooling multi-temperature operation mode or the heating multi-temperature operation mode, the air conditioning apparatus is not instructed to switch to the operation mode because the air conditioning apparatus determines that the historical operation mode of the air conditioning apparatus, i.e., the historical operation mode operated before the cooling multi-temperature operation mode or the heating multi-temperature operation mode, is the reference operation mode, so that the air conditioning apparatus is subsequently switched to the air supply mode; if the first control instruction indicates a control instruction for switching to the refrigeration mode, the air conditioning equipment can determine that the reference working mode is the refrigeration mode, and after the air conditioning equipment exits the refrigeration multi-temperature working mode or the heating multi-temperature working mode, the air conditioning equipment switches to the refrigeration mode.
Based on the foregoing embodiments, in other embodiments of the present application, step 202 may be implemented by step 202a or step 202 b:
step 202a, if the target working mode is different from the working mode of the reference working mode when the compressor is in operation, determining that the suspension time of stopping the working of the compressor is the first time.
In the embodiment of the application, the first duration is an empirical value obtained according to a plurality of experiments. When the operation mode of the target working mode is different from the operation mode of the reference working mode, setting the first duration corresponding to the pause duration for stopping the working of the compressor. The operation mode of the target operation mode when the compressor is operated is different from the operation mode of the reference operation mode when the compressor is operated, for example, the operation mode of the target operation mode when the compressor is operated is a heating operation mode and the operation mode of the reference operation mode when the compressor is operated is a cooling operation mode, or the operation mode of the target operation mode when the compressor is operated is a cooling operation mode and the operation mode of the reference operation mode when the compressor is operated is a heating operation mode.
Step 202b, if the target operation mode is the same as the operation mode of the compressor in the reference operation mode, or if the compressor in the reference operation mode stops working, determining the pause time of stopping working of the compressor as the second time.
Wherein the first time period is longer than the second time period.
In the embodiment of the present application, the second duration is an empirical value obtained according to a plurality of experiments. The target operation mode is the same as the operation mode of the compressor in the reference operation mode, and the operation mode of the compressor in the target operation mode is a refrigeration operation mode, the operation mode of the compressor in the reference operation mode is also a refrigeration operation mode, or the operation mode of the compressor in the target operation mode is a heating operation mode, and the operation mode of the compressor in the reference operation mode is also a heating operation mode. Or, since the operation mode of the compressor in the target operation mode is the heating operation mode or the heating operation mode, the compressor in the corresponding reference operation mode is stopped, i.e. the compressor is not operated. The value ranges of the first time length and the second time length are all in the range of 0 to 10 minutes, however, the smaller and the better the value of the first time length and the value of the second time length are, the possibility that the experience of the user is poor can be reduced, and the user experience effect is improved.
Based on the foregoing embodiment, in other embodiments of the present application, referring to fig. 3, before the air conditioning apparatus performs step 201, the air conditioning apparatus is further configured to perform steps 206 to 210:
Step 206, if a second control instruction for indicating the air conditioning equipment to switch to the target working mode is received, determining the current working mode of the air conditioning equipment.
Wherein the current operating mode is different from the target operating mode.
In the embodiment of the application, when the air conditioning equipment works in the current working mode, if a second control instruction for indicating the air conditioning equipment to switch to the target working mode is received, the current working mode of the air conditioning equipment is determined.
Step 207, determining a second target control parameter of the at least one target switching valve.
In the embodiment of the application, the air conditioning equipment determines the second target control parameter of the at least one target switching valve so as to meet the temperature requirement of the air output by the target working mode. The second target control parameter may be an empirical value set in advance. The second target control parameter is used to indicate the opening degree of the target switching valve. For example, three evaporators are disposed in an indoor unit of an air conditioning apparatus, air output by the corresponding evaporators can be divided into a high layer, a middle layer and a low layer from top to bottom in a space, refrigerants received by each evaporator in unit time are identical, and are assumed to be I, at this time, one target switching valve can be disposed for each of the evaporators of the high layer and the middle layer, and when the high layer and the middle layer are in a cooling multi-temperature mode or a heating multi-temperature mode, for example, the target switching valve corresponding to the high layer can be controlled to be completely closed, at this time, no refrigerant passes through the evaporator corresponding to the high layer, the target switching valve corresponding to the middle layer is in a half-open state, at this time, the refrigerant flow rate passing through the evaporator corresponding to the middle layer is I/2, and the target switching valve corresponding to the bottom layer is in a full-on state, at this time, the refrigerant flow rate passing through the evaporator corresponding to the low layer is I.
Step 208, switching the working parameter of each target switching valve to the corresponding second target control parameter.
The working parameters of each target switch valve are switched to be corresponding second target control parameters so as to realize that air with different temperatures is output by the air conditioning equipment.
Step 209, determining a target mode of a compressor of the air conditioning apparatus based on the target operation mode and the current operation mode.
In the embodiment of the application, the target working mode and the current working mode are analyzed, and the target mode of the compressor of the air conditioning equipment is determined.
Step 210, switching the working mode of the compressor to a target mode.
Based on the foregoing embodiment, in other embodiments of the present application, the indoor unit includes two evaporators, the corresponding indoor unit includes one target on-off valve, and when determining the second target control parameter of the at least one target on-off valve, step 207 may be implemented by the following steps: and determining the second target control parameter as the control parameter for controlling the closing of the target switching valve.
In this embodiment of the present application, when the indoor unit includes two evaporators, and a corresponding one of the evaporators is connected to the target switching valve, the second target control parameter is a control parameter for controlling the target switching valve to be closed.
For example, if the target switching valve is a normally open solenoid valve, the second target control parameter is a power-on control parameter to close the target switching valve.
Based on the foregoing embodiments, in other embodiments of the present application, step 209 may be implemented by steps 209a to 209 c:
step 209a, determining a first mode of the compressor corresponding to the target working mode.
In this embodiment of the present application, the first mode is a mode in which the compressor needs to operate when the air conditioning apparatus is in the target operation mode.
Step 209b, determining a second mode of the compressor corresponding to the current operation mode.
