It can be understood that when the outdoor temperature in summer is too high, the sunlight intensity is at the maximum value of the cycle period, at this time, the temperature of the cooling water in the water tank 120 rises suddenly after the water tank 120 is illuminated with high intensity for a long time, when the temperature of the cooling water in the water tank 120 approaches to the temperature of the radiator or is higher than the temperature of the radiator, the heat exchange scheme between the cooling water in the water tank 120 and the radiating fins of the radiator is meaningless, so that the heat shield 140 is additionally arranged on the water tank 120, when the sunlight intensity is too high and the sunlight time is too long, the water tank 120 can be in a shade area formed by the heat shield 140, and the heat shield 140 can block the light directly irradiated to the water tank 120.

According to the air conditioner outdoor unit 100 provided by the embodiment of the application, through the arrangement of the heat shield 140, the control of the temperature of cooling water in the water tank 120 is realized, the situation that the temperature of the cooling water is too high due to the fact that high-intensity light directly irradiates the water tank 120 is avoided, the feasibility of water cooling and heat dissipation of rainwater is guaranteed, and the heat dissipation effect of an air conditioner is optimized.

The control method of the air conditioner, the control device of the air conditioner, the electronic device and the readable storage medium provided by the embodiment of the application are described in detail below by means of specific embodiments and application scenes of the specific embodiments with reference to the accompanying drawings.

It should also be appreciated that in some embodiments, the terminal may not be a portable communication device, but rather a desktop computer having a touch-sensitive surface (e.g., a touch screen display and/or a touch pad).

In the following various embodiments, a terminal including a display and a touch sensitive surface is described. However, it should be understood that the terminal may include one or more other physical user interface devices such as a physical keyboard, mouse, and joystick.

The execution main body of the control method of the air conditioner provided in the embodiment of the present application may be an electronic device or a functional module or a functional entity in the electronic device capable of implementing the control method of the air conditioner, where the electronic device mentioned in the embodiment of the present application includes, but is not limited to, a mobile phone, a tablet computer, a camera, a wearable device, and the like, and the control method of the air conditioner provided in the embodiment of the present application is described below by taking the electronic device as an execution main body as an example.

The application also discloses a control method of the air conditioner.

In some embodiments, as shown in fig. 1, an air conditioner outdoor unit 100 includes: the spray device and the outdoor unit body 110 having the radiator, the spray nozzle of the spray device faces the radiator for spraying cooling water to the radiator.

The specific structure of the air conditioner outdoor unit 100 may be referred to the description in the above embodiments, and will not be repeated here.

With respect to the structure of the air conditioner outdoor unit 100 described above, a control method of an air conditioner applied to the structure will be described.

The control method of the air conditioner provided in the embodiment of the present application is applied to the air conditioner outdoor unit 100.

A control method of an air conditioner according to an embodiment of the present application is described below with reference to fig. 6 to 9.

In some embodiments, as shown in fig. 6, the control method of the air conditioner includes: step 210, step 220 and step 230.

Step 210, obtaining an ambient temperature.

The ambient temperature may be an outdoor intake air temperature, and in actual implementation, a temperature sensor is arranged on the radiator, the temperature sensor may be a negative temperature coefficient thermistor, and when the ambient temperature is reduced, the resistance value of the temperature sensor is increased; when the ambient temperature increases, the resistance value of the temperature sensor decreases, so that the outdoor ambient temperature can be detected during cooling or heating.

Step 220, based on the ambient temperature and the operation mode of the air conditioner, it is determined whether water can be sprayed.

The operation mode of the air conditioner may include a standby mode, a cooling mode, a heating mode, and the like.

It can be understood that one of the preconditions for determining whether water can be sprayed at this time is whether the ambient temperature at this time is greater than or equal to a preset critical value, and water can be sprayed when the ambient temperature is greater than or equal to the preset critical value and the air conditioner is in the cooling mode.

And 230, controlling the spraying device to spray water at a target spraying speed under the condition that the ambient temperature is not less than a first temperature threshold t1 and the air conditioner is in a refrigeration mode.

The first temperature threshold t1 is the preset critical value, and the first temperature threshold t1 may be adjusted according to practical situations, for example, in some embodiments, the first temperature threshold t1 is set to 25 ℃.

In this embodiment, when the working module of the air conditioner is in the cooling mode, the ambient temperature at this time is less than the first temperature threshold t1, and the operation of spraying water cannot be performed according to the judgment standard; when the working module of the air conditioner is a standby module, a heating mode or other non-refrigeration modes, the environment temperature is smaller than a first temperature threshold t1, and water spraying operation cannot be implemented according to the judgment standard; when the working module of the air conditioner is a standby module, a heating mode or other non-refrigeration modes, the environment temperature is greater than or equal to a first temperature threshold t1, and water spraying operation cannot be implemented according to the judgment standard; when the working module of the air conditioner is in the refrigeration mode, the ambient temperature is greater than or equal to the first temperature threshold t1, and then the water spraying operation can be implemented according to the judging standard.

According to the control method of the air conditioner, through the logic design of the water cooling and heat dissipation of the refrigerating and spraying rainwater, the accurate control of the time of spraying water to the spraying device is realized, the spraying device is guaranteed to spray water to the radiator only under the condition that the refrigerating mode of the air conditioner is met and the environment temperature reaches a critical value, the reliability of the whole unit is guaranteed, and meanwhile, the working safety of the whole unit is improved.

In some embodiments, as shown in fig. 7, the target spray speed may be determined based on a tray outlet temperature of a condenser of the air conditioner outdoor unit 100.

The manner of controlling the target spray rate may include a variety of ways.

The following describes embodiments of the present application in detail from two different implementation angles, respectively.

1. The target spray rate is controlled by the water pump 131.

In this embodiment, the water pump 131 may be a variable frequency water pump, the water supply pressure may be set according to the target spraying speed, then the water pump is powered on to operate, the pressure sensor monitors the pipe network pressure and becomes an electrical signal to feed back to the frequency converter, the frequency converter controls the operation of the water pump 131 through analysis processing of the feedback value and the set value, and finally the feedback value and the set value are consistent. When the target spraying speed is increased, the water consumption is increased, the system pressure is reduced, the feedback value is smaller than the set value, the output voltage and frequency of the frequency converter are increased, the rotating speed of the water pump 131 is increased, and the water yield is increased; when the target spraying speed is reduced, the water consumption is reduced, the rotation speed of the water pump 131 is reduced, the water yield is reduced, and the pipe network pressure is maintained at a set pressure value.

2. The target spray rate is controlled by a control valve.

In this embodiment, the control valve may be an opening valve, the target opening may be set according to the target spray speed, when the valve supplies water from the inlet end, water flows through the needle valve into the main valve control chamber, flows through the pilot valve and the ball valve out of the main valve control chamber to the outlet, at this time, the main valve is in a fully opened or floating state, the opening of the needle valve is adjusted, and the pressure of the pilot valve spring is adjusted, so that the opening of the main valve is kept at the target opening, and the pilot valve is automatically adjusted when the pressure changes, so that the flow is kept unchanged. When the target spraying speed is increased, the water consumption is increased, the target opening degree is increased, and the flow is increased; when the target spray speed is increased, the water consumption is reduced, the target opening degree is reduced, and the flow rate is reduced.

According to the control method of the air conditioner, through the setting of the target spraying speed, the strict control of the water yield of the spraying device is realized, on one hand, the phenomenon that the water yield is excessive due to the overlarge spraying speed is avoided, and the control method does not accord with the environment-friendly conservation concept of water resources; on the other hand, the problem that the water yield is too low due to too low spraying speed is avoided, and the heat dissipation effect cannot be expected.

In some embodiments, as shown in fig. 7, the target spray velocity V may be determined based on the following formula:

V=a++ T1, where a is a target constant, and T1 is the outlet temperature of the condenser.

The outlet temperature T1 of the condenser may be the temperature of the refrigerant at the outlet of the condenser tube. The target constant a and target coefficient ≡may be calculated from data obtained from a number of experiments.

It will be appreciated that in actual implementation, by adjusting the target spray velocity V, the outlet temperature T1 of the condenser may be adjusted, e.g., the greater the target spray velocity V, the lower the outlet temperature T1 of the condenser; the smaller the target spray velocity V, the higher the outlet temperature T1 of the condenser.

According to the control method of the air conditioner, through the design of the data relation between the target spraying speed V and the outlet temperature T1 of the condenser, the target spraying speed V is set by the outlet temperature T1 of the condenser, the condensation process of the refrigerant is precisely mastered, and the operation of the whole unit is more intelligent.

Reference may be made to the description of the above embodiments for the specific structure of the water tank 120, and the description thereof will not be repeated here.

In some embodiments, as shown in fig. 7, after step 230, the control method may further include:

in case it is determined that the water level of the water tank 120 is lower than the first water level value, or the air conditioner is not in the cooling mode, the spraying device may be controlled to stop spraying water.

It is understood that the anhydrous detection sensor 133 is disposed at a low water level of the water tank 120, and the anhydrous detection sensor 133 may transmit the water shortage signal when the water level of the water tank 120 is lower than the first water level value, if the water level of the water tank 120 is at the first water level value.

As shown in fig. 7, when the first control valve 124 and the water pump 131 are controlled to be opened, the spraying device can be controlled to spray water; the first control valve 124 and the water pump 131 are controlled to be closed, and the spraying device can be controlled to stop spraying water.

In this embodiment, when the water level of the water tank 120 is higher than the first water level value, the spraying device may be controlled to continue spraying water in the case that the air conditioner is in the cooling mode at this time; when the water level of the water tank 120 is lower than the first water level value, the spraying device can be controlled to stop spraying water under the condition that the air conditioner is in the refrigeration mode at the moment; when the water level of the water tank 120 is higher than the first water level value, the spraying device can be controlled to stop spraying water under the condition that the air conditioner is not in the refrigeration mode at the moment; when the water level of the water tank 120 is lower than the first water level value, the spraying device may be controlled to stop spraying water when the air conditioner is not in the cooling mode.

According to the control method of the air conditioner, the logic design of stopping water spraying is controlled by the spraying device, so that water spraying can not be continued under the condition that the water tank 120 is anhydrous, and the condition that the water pump 131 idles and consumes no power under the condition that no water exists is avoided; on the other hand, the spraying device can not continuously spray water after the air conditioner exits the refrigeration mode, and diligence and economy of water resources are realized.

In some embodiments, as shown in fig. 7, prior to step 220, the control method may further include: the water level of the water tank 120 is determined to be higher than the first water level value at the first water spray frequency x 1.

The first water spray frequency x1 may be adjusted according to practical situations, for example, in some embodiments, the first water spray frequency x1 is 1 time/hour.

After step 220, the control method may further include: and under the condition that the environment temperature is less than the first temperature threshold t1 or the air conditioner is not in a refrigeration mode, judging whether water spraying can be performed or not according to the second water spraying frequency x2.

The second water spray frequency x2 may be adjusted according to the actual situation, for example, in some embodiments, the second water spray frequency x2 is 1/2 hours.

It should be noted that, when the air conditioner is in the cooling mode and the ambient temperature is less than the first temperature threshold t1, the second water spraying frequency x2 may be refreshed.

After step 230, the control method may further include: in the case that it is determined that the water level of the water tank 120 is not lower than the first water level value and the air conditioner is in the cooling mode, it is judged whether to stop spraying water at the third spraying frequency x 3.

The third water spray frequency x3 may be adjusted according to the actual situation, for example, in some embodiments, the third water spray frequency x3 is 1 time/second.

In this embodiment, it is possible to detect whether the water shortage signal is transmitted from the water absence detection sensor 133 1 time every 1 hour, to determine whether water is sprayed by detecting the ambient temperature and the operation mode of the air conditioner 1 time every 2 hours after confirming that water is present in the water tank 120, and to determine whether water spraying is stopped by detecting the water level of the water tank 120 and the operation mode of the air conditioner 1 time every 1 second after spraying water by the spraying device.

It should be noted that, the air conditioner is in a standby state in a non-working mode, before detecting the water level of the water tank 120, the unit needs to be subjected to fault detection, and when the unit has a fault, the unit can be subjected to manual maintenance and repair and then subjected to fault detection again; and under the condition that the unit has no faults, the subsequent control operation can be performed.

According to the control method of the air conditioner, through the setting of the first water spraying frequency x1, the second water spraying frequency x2 and the third water spraying frequency x3, the water level of the water tank 120, the ambient temperature and the working mode of the air conditioner are periodically and regularly detected, the situation that rainwater is not sprayed when the water tank 120 is free of water and the unit fails is guaranteed, the unit works normally after failure is relieved, and therefore the stability of the unit work is improved.

In some embodiments, as shown in fig. 1, the spray device may further comprise: the first water pipe 121, the nozzle, the first control valve 124, the water storage tank, the second water pipe 125, the second control valve 127, the third water pipe 128 and the third control valve 129, the first water pipe 121 may be connected between the water tank 120 and the nozzle, the first control valve 124 may be installed in the first water pipe 121, the second water pipe 125 may be connected between the water storage tank and the water tank 120, the second control valve 127 may be installed in the second water pipe 125, the first end of the third water pipe 128 may be connected with the water storage tank, and the third control valve 129 may be installed in the third water pipe 128.

The specific structures of the first water pipe 121, the nozzle, the first control valve 124, the water storage tank, the second water pipe 125, the second control valve 127, the third water pipe 128, and the third control valve 129 may be referred to the description in the above embodiments, and will not be repeated here.

In some embodiments, as shown in fig. 8, the control method may further include the steps of:

Judging whether water can be stored based on the water level of the water tank 120 and the ambient temperature; in the case where it is determined that the water level of the water tank 120 is lower than the second water level value and the ambient temperature is not less than the second temperature threshold t2, the second control valve 127 is controlled to be opened and the third control valve 129 is controlled to be closed.

It may be appreciated that the full water detection sensor 132 is disposed at a high water level of the water tank 120, and the full water detection sensor 132 may transmit a full water signal when the water level of the water tank 120 is higher than the second water level value, and the full water detection sensor 132 is at a second water level value; when the water level of the water tank 120 is lower than the second water level value, the full water detection sensor 132 does not transmit the full water signal.

As shown in fig. 1, when the second control valve 127 is controlled to be opened, the second water pipe 125 is turned on, and the water storage tank fills water into the water tank 120; when the third control valve 129 is controlled to be closed, the third water pipe 128 is closed, and the water storage tank is blocked from draining to the outside environment.

As shown in fig. 8, when the second control valve 127 is controlled to be opened and the third control valve 129 is controlled to be closed, the water tank 120 can be controlled to store water; controlling the first control valve 124 to close and the third control valve 129 to open may control the water tank 120 to stop storing water.

The second temperature threshold t2 may be adjusted according to the actual situation, for example, in some embodiments, the second temperature threshold t2 is set to 20 ℃.

In this embodiment, when it is determined that the water level of the water tank 120 is lower than the second water level value, at which time the ambient temperature is lower than the second temperature threshold t2, water storage is not possible; when the water level of the water tank 120 is not lower than the second water level value, the ambient temperature is not lower than the second temperature threshold t2, and water storage cannot be performed; when it is determined that the water level of the water tank 120 is not lower than the second water level value, the ambient temperature is lower than the second temperature threshold t2, and water storage cannot be performed; when it is determined that the water level of the water tank 120 is lower than the second water level value, at which time the ambient temperature is not less than the second temperature threshold t2, the second control valve 127 may be controlled to be opened, and the third control valve 129 may be controlled to be closed.

According to the control method of the air conditioner, through the logic design for controlling the water storage of the water tank 120, the water level state in the water tank 120 is controlled, the water tank 120 can be timely supplemented in the water shortage state to meet the use requirement in the subsequent air conditioner refrigerating mode, and therefore the burden of detecting the water level by manpower is solved.

In some embodiments, as shown in fig. 8, before determining whether water can be stored based on the water level of the water tank 120 and the ambient temperature, the control method may further include: the water level of the water tank 120 is determined to be lower than the second water level value at the first water storage frequency y 1.

The first water storage frequency y1 may be adjusted according to practical situations, for example, in some embodiments, the first water storage frequency y1 is 1 time/hour.

After determining whether water can be stored based on the water level of the water tank 120 and the ambient temperature, the control method may further include: in the case that it is determined that the water level of the water tank 120 is not lower than the second water level value or that the ambient temperature is lower than the second temperature threshold t2, it is judged whether or not water can be stored at the second water storage frequency y 2.

The second water storage frequency y2 may be adjusted according to practical situations, for example, in some embodiments, the second water storage frequency y2 is 1/2 hours.

In case it is determined that the water level of the water tank 120 is lower than the second water level value and the ambient temperature is not less than the second temperature threshold t2, the control method may further include, after controlling the second control valve 127 to be opened and the third control valve 129 to be closed: in the case where it is determined that the water level of the water tank 120 is lower than the second water level value, it is judged whether or not to stop the water spraying at the third water storage frequency y 3.

The third water storage frequency y3 may be adjusted according to practical situations, for example, in some embodiments, the third water storage frequency y3 is 1 time/second.

In this embodiment, the full water detection sensor 132 may detect whether or not to send a full water signal 1 time every 1 hour, and after confirming that the water tank 120 is not full of water, the water level of the water tank 120 and the ambient temperature may be detected 1 time every 2 hours to determine whether or not to store water, and after the water tank 120 starts storing water, the water level of the water tank 120 may be detected 1 time every 1 second to determine whether or not to stop storing water.

According to the control method of the air conditioner, through the setting of the first water storage frequency y1, the second water storage frequency y2 and the third water storage frequency y3, the water level and the environment temperature of the water tank 120 are periodically and regularly detected, the water tank 120 is guaranteed to be full of water, rainwater cannot be reserved when a unit fails, the unit can work normally after failure is relieved, and therefore the reliability of the unit work is improved.

In some embodiments, as shown in fig. 9, the control method may further include the steps of:

judging whether the stored water can be emptied based on the water level of the water tank 120 and the ambient temperature; in the case where it is determined that the water level of the water tank 120 is not lower than the first water level value and it is determined that the ambient temperature is not greater than the third temperature threshold t3, the first control valve 124 and the third control valve 129 are controlled to be opened.

It will be appreciated that as shown in fig. 1, when the first control valve 124 is controlled to be opened, the first water pipe 121 is turned on, and the spraying device sprays water to the radiator; when the third control valve 129 is controlled to be opened, the third water pipe 128 is turned on, and the water storage tank discharges water to the outside environment.

As shown in fig. 9, when the first control valve 124, the water pump 131 and the third control valve 129 are controlled to be opened, the water tank 120 and the water storage tank can be controlled to empty the water storage; the first control valve 124 and the water pump 131 are controlled to be closed, the water tank 120 may be controlled to stop emptying the stored water, and the target spraying speed V may take the maximum value B when the water tank 120 is controlled to spray water.

The third temperature threshold t3 may be adjusted according to practical situations, for example, in some embodiments, the third temperature threshold t3 is set to 10 ℃.

It should be noted that, when the outdoor temperature is too low, the water in the water tank 120 and the water in the water storage tank may gradually condense from the liquid water into solid ice, which affects the performance of the unit, so that when the temperature is too low, the water in the water tank 120 and the water storage tank needs to be emptied.

In this embodiment, when it is determined that the water level of the water tank 120 is not lower than the first water level value, at which time the ambient temperature is greater than the third temperature threshold t3, the stored water cannot be emptied; when it is determined that the water level of the water tank 120 is lower than the first water level value, at which time the ambient temperature is not greater than the third temperature threshold t3, the stored water cannot be emptied; when it is determined that the water level of the water tank 120 is lower than the first water level value, the ambient temperature is greater than the third temperature threshold t3, and the stored water cannot be emptied; when it is determined that the water level of the water tank 120 is not lower than the first water level value, at which time the ambient temperature is not greater than the third temperature threshold t3, the first control valve 124 and the third control valve 129 may be controlled to be opened.

According to the control method of the air conditioner, through the logic design of the control water tank 120 and the water storage tank for emptying water storage, the influence of rain water freezing on the performance of the unit when the outdoor temperature is too low is avoided, so that the reliability and stability of the whole unit are improved, and the service life of the whole unit is prolonged.

In some embodiments, as shown in fig. 9, before determining whether the water storage can be emptied based on the water level of the water tank 120 and the ambient temperature, the control method may further include: the water level of the water tank 120 is determined not to be lower than the first water level value at the first drain frequency z 1.

The first drain frequency z1 may be adjusted according to practical situations, for example, in some embodiments, the first drain frequency z1 is 1 time/hour.

After determining whether the stored water can be emptied based on the water level of the water tank 120 and the ambient temperature, the control method may further include: in the case where it is determined that the water level of the water tank 120 is lower than the first water level value or it is determined that the ambient temperature is greater than the third temperature threshold t3, it is judged whether or not the stored water can be emptied at the second drain frequency z 2.

The second drain frequency z2 may be adjusted according to the actual situation, for example, in some embodiments, the second drain frequency z2 is 1/2 hours.

In the case where it is determined that the water level of the water tank 120 is not lower than the first water level value and it is determined that the ambient temperature is not greater than the third temperature threshold t3, the control method may further include, after controlling the first control valve 124 and the third control valve 129 to be opened: in the case where it is determined that the water level of the water tank 120 is not lower than the first water level value, it is judged whether to stop emptying the stored water at the third drain frequency z 3.

The third drain frequency z3 may be adjusted according to the actual situation, for example, in some embodiments, the third drain frequency z3 is 1 time/second.
