Fig. 1 is a schematic structural diagram of an intelligent air conditioner with humidification and dust removal functions provided by an embodiment of the present disclosure. 1, the smart air conditioner includes a compressor 11, a condenser 12, a throttle valve 13, an evaporator 14, a three-way valve 15 and a water spray component 16, wherein the air outlet of the compressor 11 is connected to the three-way valve 15. The inlet of the condenser 12 is connected to the first outlet of the three-way valve 15, the pressure input port of the water spray part 16 is connected to the second outlet of the three-way valve 15, and the air outlet of the condenser 12 is connected to the throttling The first port of the valve 13 is connected, the second port of the throttle valve 13 is connected with the air inlet of the evaporator 14 , and the air outlet of the evaporator 14 is connected with the air inlet of the compressor 11 . The indoor unit of the smart air conditioner is also provided with a water receiving pan for collecting condensed water on the coil of the indoor unit.

After the pressure input port of the water spraying part 16 provides enough pressure, the water spraying part 16 can spray water to the indoor environment or the interior of the indoor unit.

For example, the water spray part 16 may include: a spray head 161, a water storage chamber 162 and a piston 163, the piston 163 is arranged in the water storage chamber 162, and the water storage chamber 162 is divided into a first chamber and a second chamber, The first chamber communicates with the spray head 161 , the second chamber communicates with the pressure input port, and the first chamber is used to store the condensed water collected by the water tray. During the humidification process, the inlet and the second outlet of the three-way valve are connected, and the refrigerant flows into the pressure input port of the water storage chamber 162 from the second outlet of the three-way valve, and enters the second chamber. Next, squeeze the condensed water stored in the first chamber, so that the condensed water is sprayed out from the spray head 161 .

The water storage chamber 162 can be provided with a one-way pilot valve, so that the water in the water receiving tray can be injected into the water storage chamber 162, and when the piston 163 applies pressure to the first chamber, the water will not flow in the water storage chamber 162. Return to drip pan.

The piston 163 may include a magnetic cake, and an electromagnet may be disposed in the second chamber away from the magnetic cake. In the process of stopping the humidification, the compressor can be stopped, and then the electromagnet is energized. After the electromagnet is energized, it will generate a suction force on the magnetic cake in the piston 163, and the piston 163 will increase the first chamber and reduce the second chamber. Move in a small direction to make the refrigerant in the second chamber return to the refrigerant circulation system of the air conditioner, then close the inlet and the second outlet of the three-way valve, start the compressor, and make the air conditioner enter the normal control mode.

Fig. 2 is a schematic diagram of a method for controlling an air conditioner provided by an embodiment of the present disclosure. The method for controlling the air conditioner can be executed inside the controller of the air conditioner, can also be executed in a control terminal of the air conditioner, such as a remote controller or a control panel of the air conditioner, and can also be executed in a server of a smart home.

As shown in Figure 2, the method for controlling the air conditioner includes:

S201. Obtain the current amount of dust in the indoor air.

The current amount of dust in the room can be obtained through the dust sensor, or the current amount of dust can be obtained through the human-computer interaction device. For example, when the user thinks that the amount of dust in the room is too large, the relevant "dust" and "how much dust" input by the user can be obtained through the voice input device. ", "less" and other keywords, if the voice input device obtains the keywords of "dust" and "more", the result that the current dust amount is greater than or equal to the set dust amount can be obtained, if the voice input device obtains "dust" and "less" keywords, the result that the current dust amount is less than the set dust amount can be obtained.

S202. Connect the inlet of the three-way valve to the second outlet of the three-way valve when the current amount of dust is greater than or equal to the set amount of dust.

The inlet of the three-way valve is connected to the air outlet of the compressor, and the second outlet of the three-way valve is connected to the pressure input port of the water spraying part. When the inlet of the three-way valve is not connected to the second outlet of the three-way valve, After the refrigerant flows out of the air outlet of the compressor, it passes through the three-way valve, condenser, throttle valve and evaporator in sequence, and finally returns to the compressor at the air inlet of the compressor.

In the case that the inlet of the three-way valve is connected to the second outlet of the three-way valve, the passage between the inlet of the three-way valve and the first outlet of the three-way valve can be closed or kept connected.

If the passage between the inlet of the three-way valve and the first outlet of the three-way valve is closed, the refrigerant will flow into the inlet of the three-way valve after flowing out of the outlet of the compressor, and then flow from the second outlet of the three-way valve to Pressure input port for water spray unit.

If the connection between the inlet of the three-way valve and the second outlet of the three-way valve remains connected, the refrigerant will flow into the inlet of the three-way valve after flowing out from the outlet of the compressor. The air outlet flows out, passes through the condenser, throttle valve and evaporator in turn, and finally returns to the compressor at the air inlet of the compressor; the other part of the refrigerant flows out at the second outlet of the three-way valve, and flows in from the pressure input port of the water spray part. Inside the sprinkler unit.

The set amount of dust can be obtained based on big data analysis, or manually set by the user. If the current dust amount is greater than or equal to the set dust amount, it means that there is too much dust in the indoor air at this time, and the air conditioner needs to enter the humidification and dust removal mode.

If the current amount of dust is less than the set amount of dust, it means that there is less dust in the indoor air at this time, and the air conditioner can exit the humidification and dust removal mode. For example, the inlet of the three-way valve and the second outlet of the three-way valve The path between them is shut down.

S203. Obtain the set frequency of the compressor corresponding to the current amount of dust and the set amount of dust.

For example, the dust amount difference between the current dust amount and the set dust amount can be obtained; when the dust amount difference is less than or equal to the first dust amount, the first frequency corresponding to the first dust amount is obtained, and the first The frequency is determined as the set frequency of the compressor; when the difference in the amount of dust is greater than or equal to the second amount of dust, a second frequency corresponding to the second amount of dust is obtained, and the second frequency is determined as the setting of the compressor Frequency; wherein, the first amount of dust is less than or equal to the second amount of dust, and the first frequency is less than the second frequency.

The set frequency of the compressor is in one-to-one correspondence with the pressure provided by the compressor for the water spraying part. Obtaining the set frequency of the compressor corresponding to the current dust amount and the set dust amount can provide the water spraying part with the current dust amount. The spray pressure corresponding to the set amount of dust.

The corresponding relationship between the current dust amount, the set dust amount, and the operating frequency of the compressor can be pre-stored in the database. The corresponding operating frequency of the compressor.

In some application scenarios, the first frequency is determined as the set frequency of the compressor, so that the compressor provides a pressure of 3 MPa for the water spraying part, and the second frequency is determined as the set frequency of the compressor, so that the compressor is used for water spraying The components provide a pressure of 4MPa.

S204. Control the compressor according to the set frequency of the compressor.

The compressor is controlled according to the set frequency of the compressor so that the compressor operates at the set frequency.

In the process of using the refrigerant in the air conditioning circulation system to provide pressure for the water spraying parts, no additional noise will be generated indoors, thereby reducing the noise generated during the humidification process of the air conditioner with the humidification function, and improving the user experience.

In order to make the operating frequency of the compressor more in line with the actual working conditions, the set frequency can be compensated to make the compressor run at the compensated set frequency.

For example, after the inlet of the three-way valve is connected with the second outlet, the inlet of the three-way valve is still connected with the first outlet. In this case, controlling the compressor according to the set frequency of the compressor may include: obtaining and Set the indoor temperature and the expected indoor unit coil temperature corresponding to the current indoor temperature; obtain the first temperature difference between the current internal unit coil temperature and the expected internal unit coil temperature; the first current change in the first temperature difference When the rate of change is greater than the first set rate of change, the first increased frequency corresponding to the first current rate of change is obtained, and the operating frequency of the compressor is increased on the basis of the set frequency, and then the first increased frequency is increased.

Among them, the expected coil temperature of the indoor unit is related to the temperature control algorithm of the air conditioner. Usually, the temperature control algorithm of the air conditioner can eliminate the temperature difference between the set indoor temperature and the current indoor temperature, and the set indoor temperature and the current indoor temperature The larger the temperature difference, the higher the expected coil temperature of the indoor unit; the smaller the temperature difference between the set indoor temperature and the current indoor temperature, the lower the expected coil temperature of the indoor unit. And, under the condition that the temperature difference between the set room temperature and the current room temperature remains unchanged, if the temperature control algorithm can quickly eliminate the temperature difference between the set room temperature and the current room temperature, the expected internal The machine coil temperature is high; if the temperature control algorithm can slowly eliminate the temperature difference between the set room temperature and the current room temperature, the internal machine coil temperature is expected to be low. The corresponding relationship between the set indoor temperature, the current indoor temperature and the expected indoor unit coil temperature can be pre-stored in the database. After the set indoor temperature and the current indoor temperature are obtained, the set indoor temperature and the current indoor temperature can be obtained through the database. Corresponding expected internal coil temperature.

After the air conditioner enters the humidification and dust removal mode, part of the refrigerant in the refrigerant circulation system flows to the water spray component, resulting in a decrease in the amount of refrigerant in the refrigerant circulation system. In the case of a large amount of refrigerant in the system, adjust the operating frequency of the compressor according to the original temperature control algorithm to obtain a coil temperature of the evaporator with a lower temperature (coil temperature of the internal unit). In the case of less, the cooling efficiency of the air conditioner is reduced. Adjusting the operating frequency of the compressor according to the original temperature control algorithm can obtain a higher temperature of the internal unit coil, which may result in the inability to effectively adjust the indoor temperature.

Moreover, the less the amount of refrigerant in the system, the lower the cooling efficiency of the air conditioner. Adjusting the operating frequency of the compressor according to the original temperature control algorithm will result in a lower internal coil temperature.

The greater the first current rate of change of the first temperature difference value, the greater the tendency of the temperature of the coil of the indoor unit to decrease, that is, the worse the cooling effect of the indoor unit. On the other hand, increase the frequency of the first step to make the compressor provide greater pressure for the water spraying parts, and increase the speed of the water spraying parts to humidify the indoor air, so as to reduce the running time of the air conditioner in the humidification and dust removal mode, so that the air conditioner can be turned on as soon as possible. Switch the humidification and dust removal mode to the normal cooling mode, reduce the running time of the air conditioner in the low-efficiency cooling mode, and reduce the power consumption of the air conditioner; on the basis of the operating frequency of the compressor at the set frequency, increase the first frequency, and at the same time Further increase the cooling power of the evaporator so that the cooling power of the evaporator that provides the air conditioner can effectively adjust the indoor temperature.

The first increasing frequency is positively correlated with the first current rate of change, the greater the first current rate of change, the greater the first increasing frequency; the smaller the first current rate of change, the smaller the first increasing frequency. The corresponding relationship between the first increasing frequency and the first current rate of change may be pre-stored in the database. After the first current rate of change is obtained, the first current rate of change corresponding to the first increasing frequency can be obtained through the database.

The first setting change rate can be determined in the following manner: obtaining the first dust removal duration from the moment when the air conditioner enters the dust removal mode to the current moment, and obtaining the first setting change rate corresponding to the first dust removal duration.

After the amount of refrigerant in the refrigerant circulation system decreases, the cooling efficiency of the internal unit decreases to a relatively low value, and the coil temperature of the internal unit increases until the heat release rate of the refrigerant in the evaporator is balanced with the heat absorption rate of the indoor air. The coil temperature stops increasing, and during this process, the rate of increase of the coil temperature of the internal unit changes from fast to slow. That is, the coil temperature of the internal unit is in one-to-one correspondence with the first dust removal duration.

The corresponding relationship between the first dust removal duration and the first setting change rate can be pre-stored in the database. After the first dust removal duration is obtained, the first setting change rate corresponding to the first dust removal duration can be obtained through the database.

Setting the first setting change rate corresponding to the first dust removal time length can monitor the first current change rate throughout the whole process after the air conditioner enters the humidification and dust removal mode, which is more in line with the operating state of the air conditioner.

The above-mentioned first setting change rate can balance the cooling rate and power consumption. The larger the value of the first setting power, the lower the power consumption of the air conditioner in the humidification and dust removal mode, but it may reduce the ability of the air conditioner to adjust the indoor temperature; The smaller the value of the first set power, the stronger the ability of the air conditioner to adjust the indoor temperature, but the power consumption of the air conditioner may be increased. The embodiments of the present disclosure do not specifically limit the value of the first set power, and those skilled in the art can select a specific value of the first set power that meets the actual situation according to the actual meaning of the first set power.

After increasing the operating frequency of the compressor on the basis of the set frequency, and increasing the first increased frequency, the method for controlling the air conditioner may further include: obtaining The first increased opening degree of the throttle valve; the first increased opening degree of the throttle valve is increased.

For example, when the first temperature difference is less than or equal to the first set temperature difference, it is determined that the first increased opening is zero; when the first temperature difference is greater than the first set temperature difference, it is determined that A first increased opening positively correlated with the first temperature difference is generated. The corresponding relationship between the first temperature difference and the first increased opening can be pre-stored in the database. The first increase opening.

Increasing the opening degree of the throttle valve by the first increase can increase the amount of refrigerant flowing into the evaporator from the condenser and increase the cooling power of the evaporator so that the evaporator can maintain a better cooling capacity. Of course, in the process of determining the first increased opening, it is necessary to ensure that the evaporation temperature corresponding to the evaporation pressure of the evaporator is less than or equal to the set indoor temperature.

Optionally, obtaining the first increased opening of the throttle valve corresponding to the first temperature difference and the first set temperature difference includes: obtaining a first current rate of change with the first temperature difference, a first The first increased opening degree of the throttle valve corresponding to the temperature difference value and the first set temperature difference value. When the first temperature difference is greater than or equal to the first set temperature difference, a first increased opening degree positively correlated with the first temperature difference and positively correlated with the first current rate of change is determined. The corresponding relationship between the first temperature difference, the first current rate of change and the first increased opening can be pre-stored in the database, and after the first temperature difference and the first current rate of change are obtained, the first temperature The first increased opening corresponding to the difference and the first current rate of change.

In this way, the opening degree of the throttle valve can be adjusted in a more timely manner, and a better effect of maintaining the indoor temperature can be obtained.

Alternatively, controlling the compressor according to the set frequency of the compressor may include: obtaining the expected indoor air outlet temperature corresponding to the set indoor temperature and the current indoor temperature; obtaining the current indoor air outlet temperature and the expected indoor air outlet temperature The second temperature difference value; in the case that the second current rate of change of the first temperature difference value is greater than the second set rate of change, the second increased frequency corresponding to the second current rate of change is obtained, and the operation of the compressor On the basis of the set frequency, the frequency is increased by a second frequency.

Among them, the expected air outlet temperature of the indoor unit is related to the temperature control algorithm of the air conditioner. Usually, the temperature control algorithm of the air conditioner can eliminate the temperature difference between the set indoor temperature and the current indoor temperature, and the set indoor temperature and the current indoor temperature The larger the temperature difference, the higher the expected air outlet temperature of the indoor unit; the smaller the temperature difference between the set indoor temperature and the current indoor temperature, the lower the expected air outlet temperature of the indoor unit. And, under the condition that the temperature difference between the set room temperature and the current room temperature remains unchanged, if the temperature control algorithm can quickly eliminate the temperature difference between the set room temperature and the current room temperature, the expected internal The air outlet temperature of the indoor unit is high; if the temperature control algorithm can slowly eliminate the temperature difference between the set indoor temperature and the current indoor temperature, the expected air outlet temperature of the indoor unit is low. The corresponding relationship between the set indoor temperature, the current indoor temperature and the expected air outlet temperature of the indoor unit can be pre-stored in the database. The corresponding expected indoor unit outlet air temperature.

After the air conditioner enters the humidification and dust removal mode, part of the refrigerant in the refrigerant circulation system flows to the water spray component, resulting in a decrease in the amount of refrigerant in the refrigerant circulation system. When the amount of refrigerant in the system is large, adjust the operating frequency of the compressor according to the original temperature control algorithm to obtain a lower temperature of the air outlet of the internal unit. Efficiency is reduced. Adjusting the operating frequency of the compressor according to the original temperature control algorithm can obtain a higher temperature of the air outlet temperature of the indoor unit, which may result in the inability to effectively adjust the indoor temperature.

Moreover, the less the amount of refrigerant in the system is, the lower the cooling efficiency of the air conditioner will be. Adjusting the operating frequency of the compressor according to the original temperature control algorithm will result in a lower outlet air temperature of the indoor unit.

The greater the second current rate of change of the second temperature difference, the greater the tendency of the air outlet temperature of the indoor unit to decrease, that is, the worse the cooling effect of the indoor unit. Then increase the second boost frequency to make the compressor provide greater pressure for the water spraying parts and increase the speed of the water spraying parts to humidify the indoor air, so as to reduce the running time of the air conditioner in the humidification and dust removal mode, so that the air conditioner can be turned on as soon as possible. Switch the humidification and dust removal mode to the normal cooling mode, reduce the running time of the air conditioner in the low-efficiency cooling mode, and reduce the power consumption of the air conditioner; on the basis of the operating frequency of the compressor at the set frequency, increase the second frequency, and at the same time Further increase the cooling power of the evaporator so that the cooling power of the evaporator that provides the air conditioner can effectively adjust the indoor temperature.

The second increasing frequency is positively correlated with the second current rate of change, the greater the second current rate of change, the greater the second increasing frequency; the smaller the second current rate of change, the smaller the second increasing frequency. The corresponding relationship between the second increasing frequency and the second current rate of change may be pre-stored in the database. After the second current rate of change is obtained, the second increasing frequency corresponding to the second current rate of change can be obtained.

The second setting change rate can be determined in the following manner: obtain the second dust removal duration from the moment when the air conditioner enters the dust removal mode to the current moment, and obtain the second setting change rate corresponding to the second dust removal duration.

After the amount of refrigerant in the refrigerant circulation system decreases, the cooling efficiency of the internal unit decreases to a relatively low value, and the outlet air temperature of the internal unit increases until the heat release rate of the refrigerant in the evaporator is balanced with the heat absorption rate of the indoor air. The air outlet temperature stops increasing. During this process, the air outlet temperature of the indoor unit increases from fast to slow. That is, there is a one-to-one correspondence between the air outlet temperature of the indoor unit and the second dust removal duration.

The corresponding relationship between the second dust removal duration and the second set rate of change can be pre-stored in the database. After the second dust removal duration is obtained, the second set rate of change corresponding to the second dust removal duration can be obtained through the database.

Setting the second set change rate corresponding to the second dust removal time length can monitor the second current change rate throughout the whole process after the air conditioner enters the humidification and dust removal mode, which is more in line with the operating state of the air conditioner.

The above-mentioned second setting rate of change can balance the cooling rate and power consumption. The larger the value of the second setting power, the lower the power consumption of the air conditioner in the humidification and dust removal mode, but it may reduce the ability of the air conditioner to adjust the indoor temperature; The smaller the value of the second set power, the stronger the ability of the air conditioner to adjust the indoor temperature, but the power consumption of the air conditioner may be increased. The embodiment of the present disclosure does not specifically limit the value of the second set power, and those skilled in the art can select a specific value of the second set power that meets the actual situation according to the actual meaning of the second set power.

After the operating frequency of the compressor is increased on the basis of the set frequency, and the second increased frequency is increased, the method for controlling the air conditioner may further include: obtaining the temperature corresponding to the second temperature difference and the second set temperature difference The second increase opening degree of the throttle valve; increase the opening degree of the throttle valve second increase opening degree.

For example, when the second temperature difference is less than or equal to the second set temperature difference, it is determined that the second increased opening is zero; when the second temperature difference is greater than the second set temperature difference, it is determined that A second increased opening positively correlated with the second temperature difference is generated. The corresponding relationship between the second temperature difference and the second increased opening can be pre-stored in the database.
