Fig. 2 is a flowchart of a method for controlling an air conditioner according to an embodiment of the present disclosure. With reference to fig. 2, an embodiment of the present disclosure provides a method for controlling an air conditioner to implement control of the air conditioner, where the method may include:
and S21, under the condition that the controller determines that the air conditioner operates, determining a target heat exchange pipeline and a target water inlet valve according to the operation mode of the air conditioner.
Here, embodiments of the present disclosure may provide various implementations for determining air conditioner operation, and corresponding operation modes and operation temperatures. The following examples are given.
In one mode, a user can send an operation instruction including an operation mode and an operation temperature of the air conditioner to the controller through a remote control terminal associated with the air conditioner, so that the controller determines that the air conditioner is in an operation state, and the corresponding operation mode and the corresponding operation temperature according to the operation instruction. The remote control terminal associated with the air conditioner can be an air conditioner remote controller or an intelligent terminal which is in wireless communication with the air conditioner. And wireless communication modes comprise one or more of Wi-Fi communication, zigbee protocol communication and Bluetooth communication.
The intelligent terminal is, for example, a mobile device, a computer, a vehicle-mounted device built in a floating car, or any combination thereof. In some embodiments, the mobile device may include, for example, a cell phone, a smart home device, a wearable device, a smart mobile device, a virtual reality device, and the like, or any combination thereof.
In another mode, the controller may obtain a current indoor environment parameter, and control the air conditioner to operate in a corresponding operation mode and operation temperature according to the current indoor environment parameter. For example, the air conditioner is controlled to start up and operate when one or more of the current indoor temperature, the current indoor humidity and the current indoor air quality satisfy the operating condition. And meanwhile, according to the current indoor environment parameters, determining the corresponding operation mode and operation temperature from the correlation among the indoor environment parameters, the operation mode and the operation temperature of the air conditioner. Like this, help improving the intelligent degree of air conditioner, reduce user's operation complexity simultaneously, improve user's use and experience.
Here, the correlation between the indoor environment parameter, the operation mode of the air conditioner, and the operation temperature may be a correlation between the indoor environment parameter and the operation mode of the air conditioner, and a correlation between the indoor environment parameter and the operation temperature of the air conditioner.
Alternatively, the controller may determine the target heat exchange line and the target water inlet valve according to an operation mode of the air conditioner, and may include: the controller determines a target heat exchange pipeline according to the operation mode; and the controller determines a target water inlet valve of a cold water inlet pipe connected with the target heat exchange pipeline according to the target heat exchange pipeline. Therefore, the heat dissipation position of the air conditioner can be accurately determined, and the cold water can be conveniently heated by utilizing the residual heat subsequently.
Optionally, the controller determines the target heat exchange line according to the operation mode, and may include: under the condition that the operation mode is a refrigeration mode, the controller determines the first heat exchange pipeline as a target heat exchange pipeline; in case that the operation mode is the heating mode, the controller determines the second heat exchange line as a target heat exchange line. When the air conditioner is in a refrigeration mode, the heat exchanger of the outdoor unit is in a heat dissipation state; when the air conditioner is in a heating mode, the heat exchanger of the indoor unit is in a heat dissipation state. Therefore, the heat dissipation position of the air conditioner can be accurately determined, and the cold water can be conveniently heated by utilizing the waste heat dissipated by the heat exchanger subsequently.
And S22, adjusting the opening degree of the target water inlet valve by the controller according to the outdoor environment temperature, the operation mode and the operation temperature of the air conditioner so as to adjust the heat consumption in the target heat exchange pipeline.
Here, if the outdoor unit of the air conditioner is provided with a temperature sensor, the outdoor ambient temperature can be very conveniently obtained. Alternatively, if the controller can obtain a weather information base containing the outdoor ambient temperature, the outdoor ambient temperature can be obtained quickly when needed.
The weather information base can be stored in a cloud server associated with the controller, and when the outdoor environment temperature is determined to be needed, the cloud server can obtain the weather information base in a local reading mode. Alternatively, the weather information base may be stored in another data storage server, and the controller may obtain the weather information base by accessing the data storage server when needed. The weather information base can be obtained quickly and conveniently in the above mode. The embodiment of the present disclosure may not be particularly limited with respect to the implementation manner of obtaining the weather information base.
Optionally, the operation mode is a cooling mode, and the adjusting of the opening degree of the target water inlet valve by the controller according to the outdoor environment temperature, the operation mode, and the operation temperature of the air conditioner may include: when the outdoor environment temperature is greater than or equal to a first preset temperature and the operation temperature is less than or equal to a second preset temperature, the controller sets the opening of the target water inlet valve to be the maximum opening of the adjustable opening interval; when the outdoor environment temperature is less than or equal to the third preset temperature and the operation temperature is greater than or equal to the fourth preset temperature, the controller sets the opening of the target water inlet valve to be the minimum opening of the adjustable opening interval; the first preset temperature is higher than the third preset temperature, and the second preset temperature is lower than the fourth preset temperature.
When the air conditioner is in a refrigeration mode, the heat exchanger of the outdoor unit is in a heat dissipation state, and the higher the outdoor environment temperature is, the lower the running temperature of the air conditioner is, and the more heat is dissipated by the heat exchanger of the outdoor unit. Therefore, under the condition that the outdoor environment temperature is greater than or equal to the first preset temperature and the operation temperature is less than or equal to the second preset temperature, the opening of the target water inlet valve is set to be the maximum opening of the opening-adjustable interval, waste heat dissipated by the outdoor unit heat exchanger is utilized beneficially, more cold water is heated, and the utilization rate of heat energy is guaranteed. Meanwhile, the cold water absorbs the waste heat of the air conditioner, so that the heat dissipation efficiency of the heat exchanger is improved, and the operation effect of the air conditioner is improved. And under the conditions that the outdoor environment temperature is less than or equal to the third preset temperature and the operation temperature is greater than or equal to the fourth preset temperature, the opening of the target water inlet valve is set to be the minimum opening of the adjustable opening interval, so that the refrigeration effect of the air conditioner is ensured, the minimum supply of hot water is ensured, and the intelligent degree of a user is improved.
Here, the first preset temperature may be in a range of 35 to 40 ℃, and preferably 40 ℃. The second predetermined temperature may range from 14 ℃ to 20 ℃, preferably 16 ℃. Therefore, the influence of excessive heat energy on the refrigeration effect of the air conditioner can be avoided.
The third preset temperature can be 25-30 ℃, preferably 30 ℃. The value range of the fourth preset temperature can be 21-28 ℃, and is preferably 25 ℃. Thus, the minimum supply amount of hot water can be ensured while the refrigeration effect of the air conditioner is ensured.
The maximum opening degree of the opening degree adjustable interval can indicate the opening degree of the target water inlet valve at the maximum flow rate. The minimum opening of the adjustable opening interval can be the opening of the target water inlet valve at the minimum flow. Different maximum opening degrees and minimum opening degrees are corresponded to different valve products. Therefore, the maximum opening and the minimum opening of the target water inlet valve are not limited in value, and only the maximum flow corresponding to the maximum opening needs to be ensured to be 3 times of the minimum flow corresponding to the minimum opening.
Further, the method for controlling the air conditioner may further include: when the outdoor environment temperature is higher than the third preset temperature and lower than the first preset temperature, the opening degree of the target water inlet valve adjusted between the maximum opening degree and the minimum opening degree is positively correlated with the outdoor environment temperature; and/or, the opening degree of the target water inlet valve adjusted between the maximum opening degree and the minimum opening degree is in negative correlation with the operation temperature under the condition that the operation temperature is higher than the second preset temperature and lower than the fourth preset temperature. Therefore, the higher the outdoor environment temperature is, and/or the lower the air conditioner operation temperature is, the more heat the outdoor unit radiator radiates, the more waste heat the air conditioner can use, and the more cold water is needed. Therefore, the opening degree of the target water inlet valve is adjusted according to the change of the outdoor environment temperature and the running temperature of the air conditioner, and the accurate utilization of the waste heat can be realized, so that the intelligent degree of the air conditioner is improved, and the use experience of a user is improved.
Alternatively, the operation mode is a heating mode, and the controller adjusts the opening degree of the target water inlet valve according to the outdoor ambient temperature, the operation mode, and the operation temperature of the air conditioner, and may include: when the outdoor environment temperature is less than or equal to the fifth preset temperature and the operation temperature is greater than or equal to the sixth preset temperature, the controller sets the opening of the target water inlet valve to be the maximum opening of the adjustable opening interval; when the outdoor environment temperature is greater than or equal to the seventh preset temperature and the operation temperature is less than or equal to the eighth preset temperature, the controller sets the opening degree of the target water inlet valve to be the minimum opening degree of the adjustable opening degree interval; the fifth preset temperature is lower than the seventh preset temperature, and the sixth preset temperature is higher than the eighth preset temperature.
When the air conditioner is in a heating mode, the heat exchanger of the indoor unit is in a heat dissipation state, and the lower the outdoor environment temperature is, the higher the running temperature of the air conditioner is, and the more heat is dissipated by the heat exchanger of the indoor unit. Therefore, under the condition that the outdoor environment temperature is less than or equal to the fifth preset temperature and the operation temperature is greater than or equal to the sixth preset temperature, the opening of the target water inlet valve is set to be the maximum opening of the adjustable opening interval, waste heat dissipated by the heat exchanger of the indoor unit is utilized beneficially, more cold water is heated, and the utilization rate of heat energy is guaranteed. Meanwhile, the cold water absorbs the waste heat of the air conditioner, so that the heat dissipation efficiency of the heat exchanger is improved, and the operation effect of the air conditioner is improved. When the outdoor environment temperature is higher than or equal to the seventh preset temperature and the operation temperature is lower than or equal to the eighth preset temperature, the opening degree of the target water inlet valve is set to be the minimum opening degree of the adjustable opening degree interval, so that the air conditioning heat effect is guaranteed, the minimum supply amount of hot water is guaranteed, and the intelligent degree of a user is improved.
Here, the value of the fifth preset temperature may range from 10 ℃ to 15 ℃, and is preferably 10 ℃. The value range of the sixth preset temperature can be 23-30 ℃, and is preferably 28 ℃. Therefore, the influence of excessive heat energy on the heating effect of the air conditioner can be avoided.
The value range of the seventh preset temperature can be-20-0 ℃, and is preferably-5 ℃. The eighth preset temperature may be 15 to 22 ℃, preferably 16 ℃. This helps to ensure a minimum supply of hot water while ensuring the thermal effect of the air conditioning.
Optionally, the method for controlling an air conditioner may further include: when the outdoor environment temperature is higher than the seventh preset temperature and lower than the fifth preset temperature, the opening degree of the target water inlet valve adjusted between the maximum opening degree and the minimum opening degree is in negative correlation with the outdoor environment temperature; and/or the opening degree of the target water inlet valve adjusted between the maximum opening degree and the minimum opening degree is positively correlated with the operation temperature under the condition that the operation temperature is higher than the eighth preset temperature and lower than the sixth preset temperature. Therefore, the lower the outdoor environment temperature is, and/or the higher the air conditioner running temperature is, the more heat the indoor unit radiator emits is, the more waste heat the air conditioner can utilize is, and the more cold water is needed. Therefore, the opening degree of the target water inlet valve is adjusted according to the change of the outdoor environment temperature and the running temperature of the air conditioner, and the accurate utilization of the waste heat can be realized, so that the intelligent degree of the air conditioner is improved, and the use experience of a user is improved.
Optionally, the water storage device comprises a heat preservation heating module, and the method for controlling the air conditioner may further comprise: and under the condition that the air conditioner is standby, the controller sets the opening degree of a water inlet valve of the first cold water inlet pipe to be the minimum opening degree and controls the heat-insulating heating module to be opened. Thus, even if the air conditioner does not work, the minimum supply amount of hot water can be ensured, and the intelligent degree of the user is improved.
Here, the air conditioner standby may mean that the air conditioner is in a shutdown state, or the air conditioner is in a sleep state with low power consumption. Accordingly, the embodiments of the present disclosure may provide various implementations to determine the standby state of the air conditioner, which are exemplified below.
In one mode, a user may send a standby operation instruction including shutdown control or sleep control to the controller through a remote control terminal associated with the air conditioner, so that the controller determines that the air conditioner is in a standby state according to the standby operation instruction. For the remote control terminal related to the air conditioner, reference may be made to the remote control terminal in the above embodiment for determining the operation of the air conditioner, and the corresponding operation mode and operation temperature, which are not described herein again.
In another mode, the controller may obtain a current indoor environment parameter and control the air conditioner to be in standby according to the current indoor environment parameter. For example, the air conditioner is controlled to be in standby in a case where one or more of the current indoor temperature, the current indoor humidity, and the current indoor air quality satisfy the standby condition. Like this, help improving the intelligent degree of air conditioner, reduce user's operation complexity simultaneously, improve user's use and experience.
By adopting the method for controlling the air conditioner, provided by the embodiment of the disclosure, under the condition that the operation of the air conditioner is determined, the target heat exchange pipeline and the target water inlet valve can be determined according to the operation mode of the air conditioner, so that the opening degree of the target water inlet valve can be adjusted according to the outdoor environment temperature, the operation mode and the operation temperature of the air conditioner, the heat usage amount in the target heat exchange pipeline is adjusted according to the cold water inflow amount, the accurate utilization of waste heat is realized, and the intelligent degree of the air conditioner and the use experience of a user are improved.
In addition, as shown in fig. 1, the indoor unit includes an auxiliary heating module 19, and the method for controlling an air conditioner may further include: when the operation mode is a heating mode and the air outlet temperature of the air conditioner is less than or equal to the preset air outlet temperature, the controller controls the auxiliary heating module to be started; and under the condition that the temperature of the water stored in the water storage device is greater than or equal to the preset water temperature, the controller controls the auxiliary heating module to be closed. Therefore, the excessive use of heat can be avoided while hot water is supplied, and the heating effect of the air conditioner is ensured; and when the hot water temperature reaches the standard, the auxiliary heating module is closed, so that the energy consumption of the air conditioner can be reduced, and the resources are saved.
Here, the auxiliary heat module may be a PTC (Positive Temperature Coefficient thermistor) heating module.
Optionally, the method for controlling an air conditioner may further include: and under the condition that the controller obtains a water taking control instruction, controlling the water outlet valve to open. Therefore, the user can conveniently take hot water, and the use experience of the user is improved.
The user can send the water taking control instruction to the controller in a mode of voice or manually operating a remote control terminal associated with the air conditioner.
