In order to maintain consistency and aesthetics, most office buildings or residences increase the grating at the location where the outdoor unit of the air conditioner is placed to conceal the outdoor unit of the air conditioner, but the presence of the grating can affect the heat dissipation efficiency of the outdoor unit of the air conditioner.

[0047] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below with reference to the drawings in the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0048] In the description of the present application, the description of the terms "one embodiment", "some embodiments", "an example", "a specific example", or "some examples" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In the present application, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples. In addition, the skilled in the art can combine and combine the different embodiments or examples described in the present application and the features of the different embodiments or examples without contradiction.

[0049] The cooling control method, control device and air conditioner of the outdoor unit of the air conditioner are described below with reference to the accompanying drawings. Before the embodiments of the present application are described in detail, the entire application scenario is described first. The cooling control method, control device, electronic device and computer readable storage medium of the outdoor unit of the air conditioner of the embodiments of the present application can be applied to the local air conditioner, the cloud platform in the Internet field, or the cloud platform in other types of Internet fields, or can also be applied to third-party devices. The third-party devices can include mobile phones, tablet computers, notebook computers, vehicle-mounted computers and other smart terminals, and various types of devices.

[0050] The cooling control method suitable for the air conditioner is taken as an example below, and it should be understood that the control method of the embodiments of the present application can also be applied to the cloud platform and the third-party devices.

[0051] As shown in Figure 1 , the cooling control method of the outdoor unit of the air conditioner according to the first aspect of the present application comprises:

[0052] Step S1, receiving a signal that the air conditioner is in a cooling mode, obtaining the condenser temperature in the outdoor unit 1 of the air conditioner and the outdoor environment temperature of the outdoor environment where the outdoor unit 1 is located;

[0053] Step S2, according to the condenser temperature and the outdoor environment temperature satisfying the first set condition, controlling the spraying device to spray the outdoor unit 1, wherein the spraying device comprises a spraying head 3 arranged inside the outdoor unit 1 and a branch pipe 4 communicating with the drain pipe 7 of the indoor unit 2, and the branch pipe 4 is used to transport the condensate water of the indoor unit 2 to the spraying head 3.

[0054] It can be understood that in the air conditioner to which the cooling control method of the present application is applied, the outdoor unit 1 of the air conditioner is additionally provided with a spraying device, as shown in Figure 3 , the spraying device is a cooling device for spraying cold water to the outdoor unit 1 to achieve cooling of the outdoor unit 1, and specifically, the spraying device is composed of a spraying head 3 and a branch pipe 4, and the branch pipe 4 communicates the drain pipe 7 of the indoor unit 2 with the spraying head 3. When the spraying device is turned on, the condensate water generated by the indoor unit 2 flows to the spraying head 3 through the branch pipe 4, and sprays water to the outdoor unit 1 through the spraying head 3, thereby achieving cooling of the outdoor unit 1.

[0055] The cooling control method of the outdoor unit of the air conditioner according to the embodiment of the present application has the following specific working process: when the air conditioner is turned on and runs in the cooling mode, the temperature of the condenser in the outdoor unit 1 will gradually increase with the prolongation of the running time. In order to realize the cooling control of the outdoor unit of the air conditioner, the controller runs the cooling control method of the present application. Specifically, after receiving the signal that the air conditioner is in the cooling mode, the controller first acquires the condenser temperature in the outdoor unit 1 of the air conditioner and the outdoor environment temperature of the outdoor environment where the outdoor unit 1 is located. Then, the condenser temperature and the outdoor environment temperature are compared and the comparison result is further analyzed and judged. After determining that the above two parameters meet the first set condition, it is proved that the current condenser temperature is too high, that is, the heat dissipation effect of the outdoor unit 1 is poor. Therefore, in order to cool the outdoor unit 1 and the condenser in the outdoor unit 1, the controller will directly control the spraying device to be turned on to spray the outdoor unit 1, so as to cool and dissipate heat for the outdoor unit 1 by the cooled condensate water.

[0056] In the related art, in summer, the air conditioner has become an indispensable part of daily life. However, when using the air conditioner, poor heat dissipation of the outdoor unit of the air conditioner will lead to poor heat exchange, thereby affecting the cooling effect of the indoor unit of the air conditioner, and even causing the outdoor unit to malfunction. In order to maintain the consistency and beauty of the appearance, most office buildings or residences usually increase the grating where the outdoor unit of the air conditioner is located to hide the outdoor unit of the air conditioner, but the existence of the grating will affect the heat dissipation efficiency of the outdoor unit of the air conditioner. First, the grating will reduce the air flow channel, causing poor air flow. Second, the existence of the grating will increase the resistance of the air conditioner, so that the air conditioner needs more energy to run, thereby increasing the energy consumption.

[0057] Generally, optimizing the design of the grating can improve the heat dissipation efficiency of the air conditioner. The aperture size of the grating should be reasonably designed according to the radiator area of the air conditioner, the radiator material, the working environment and other factors. In addition, the structure of the grating also needs to consider the degree of smoothness of air flow, and a streamlined design can be used to reduce resistance and improve heat dissipation efficiency. The cleaning of the grating will also affect the heat dissipation effect of the air conditioner. If dust, dirt and other substances accumulate on the grating, the air flow will be hindered. Regular cleaning of the grating is one of the important measures to maintain the heat dissipation effect of the air conditioner. Therefore, the existing solutions to the influence of the grating on heat dissipation are basically optimized from the grating itself.

[0058] For example, the existing technology mainly uses the following ways to improve the heat dissipation effect: (1) optimizing the design of the grating to improve the heat dissipation efficiency of the air conditioner, (2) improving the material and cleanliness of the grating. However, since the grating design of each office building and residence is different, most grating designs mainly consider the coordination and beauty of the building, and do not consider the heat dissipation of the outdoor unit of the air conditioner. Therefore, when designing the outdoor unit of the air conditioner, the influence of the grating on the heat dissipation of the outdoor unit of the air conditioner needs to be considered.

[0059] In conclusion, in order to solve the technical defects in the related art, the application provides a cooling control method for an outdoor unit of an air conditioner, which aims to solve the influence of the grille on the heat dissipation of the outdoor unit 1 itself and reduce the outlet air temperature of the indoor unit 2. Specifically, the method does not need to optimize the grille, but only needs to change the outdoor unit 1 device and the air conditioner control logic to achieve the purpose of increasing the heat dissipation of the outdoor unit 1 and reducing the outlet air temperature of the indoor unit 2, thereby further improving the refrigeration effect of the air conditioner, avoiding the failure of the air conditioner to ensure the normal operation of the air conditioner, and improving the user experience.

[0060] According to some embodiments of the application, the first set condition is that the condenser temperature is higher than the outdoor environment temperature and the temperature difference between the condenser temperature and the outdoor environment temperature is greater than the first set temperature difference and lasts for at least the first set time length.

[0061] For example, the first set condition is that the condenser temperature is higher than the outdoor environment temperature and the temperature difference between the condenser temperature and the outdoor environment temperature is greater than 3°C and lasts for at least one hour.

[0062] It should be pointed out that the first set temperature difference and the first set time length are both preset values, and the above parameters can be selected according to the environment where the air conditioner is located and the use requirements of the user, etc. The specific values of the first set temperature difference and the first set time length are not limited in the application.

[0063] According to some embodiments of the application, the step of controlling the spraying device to spray the outdoor unit 1 comprises:

[0064] If the water pump 5 in the spraying device is determined to be turned on, then the speed of the water pump 5 is adjusted according to the temperature difference between the condenser temperature and the outdoor environment temperature, wherein, as shown in the figure, the water pump 5 is arranged on the branch pipe 4. Figure 3

[0065] In this way, by adjusting the speed of the water pump 5, the cooling effect of the spraying device on the outdoor unit 1 can be adjusted. It can be understood that the higher the condenser temperature, the better the cooling effect required by the outdoor unit 1, and at this time the speed of the water pump 5 needs to be adjusted to be higher, so as to provide more cooling water to spray the outdoor unit 1 and improve its heat dissipation effect.

[0066] Further, the step of adjusting the speed of the water pump 5 according to the temperature difference between the condenser temperature and the outdoor environment temperature comprises:

[0067] In the case that the temperature difference between the condenser temperature and the outdoor environment temperature is in the first temperature difference interval, the speed of the water pump 5 is adjusted to the first speed;

[0068] ​In a case where the temperature difference between the condenser temperature and the outdoor ambient temperature is in the second temperature difference interval, the water pump 5 rotation speed is adjusted to a second rotation speed;

[0069] In a case where the temperature difference between the condenser temperature and the outdoor ambient temperature is in the third temperature difference interval, the water pump 5 rotation speed is adjusted to a maximum rotation speed;

[0070] The first temperature difference interval is smaller than the second temperature difference interval, and the second temperature difference interval is smaller than the third temperature difference interval, and the first rotation speed is smaller than the second rotation speed, and the second rotation speed is smaller than the maximum rotation speed.

[0071] In this way, when the temperature difference between the condenser temperature and the outdoor ambient temperature is in different interval ranges, it proves that the heat dissipation demand of the current outdoor unit 1 is also different, that is, the higher the temperature difference value, the higher the heat dissipation demand of the outdoor unit 1, at this time, in order to match the heat dissipation demand of the current outdoor unit 1, the controller needs to increase the rotation speed of the water pump 5 to a set level, for example, the first rotation speed matched with the first temperature difference interval, the second rotation speed matched with the second temperature difference interval, and the maximum rotation speed matched with the third temperature difference interval.

[0072] According to some embodiments of the present application, after the step of controlling the spraying device to spray the outdoor unit 1, the cooling control method of the air conditioner outdoor unit further comprises:

[0073] It is determined that the condenser temperature is less than or equal to the outdoor ambient temperature, and the spraying device is controlled to be closed, at this time, as shown in Figure 3 , the water pump 5 in the spraying device is closed, and the drain valve 6 on the branch pipe 4 is closed.

[0074] It can be understood that if the cooling capacity provided by the spraying device to the outdoor unit 1 is greater than the heat generated by the outdoor unit 1 itself during operation, the temperature of the outdoor unit 1 will continuously decrease under the spraying effect until the condenser temperature is less than or equal to the outdoor ambient temperature, at this time, the outdoor unit 1 returns to the normal operating state, therefore, the controller can directly close the spraying device.

[0075] As shown in Figure 4 and 5 , according to some embodiments of the present application, the air outlet 11 of the outdoor unit 1 is provided with an air outlet grille, and the air outlet grille comprises a plurality of air outlet grille pieces 8, and the air outlet grille pieces 8 are rotatably arranged relative to the air outlet 11.

[0076] After the step of controlling the spraying device to spray the outdoor unit 1, the cooling control method of the air conditioner outdoor unit further comprises:

[0077] In a case where the spraying device is opened and continuously operated for at least a second set time, it is determined that the condenser temperature and the outdoor ambient temperature satisfy a second set condition, and then the rotation direction of the air outlet grille piece 8 is adjusted to be perpendicular to the air outlet 11.

[0078] In the embodiment, when the spraying device continuously operates for a long time (for example, a second set time), if the condenser temperature and the outdoor environment temperature satisfy the second set condition, it is proved that the condenser temperature of the outdoor unit 1 is still at a high temperature level and fails to reach a normal temperature level, at this time, the outdoor unit 1 still has a high heat dissipation requirement, at this time, in order to realize further heat dissipation of the outdoor unit 1, the application controls the rotating direction of the air outlet grid piece 8 so that the rotating direction of the air outlet grid piece 8 is perpendicular to the air outlet 11, thereby forming a wind deflector by the air outlet grid piece 8, and directly guiding the hot air flowing out of the air outlet 11 to the outside of the grid, which can reduce the influence of the high-temperature outgoing air on the grid inlet temperature in the grid, and further improve the heat exchange efficiency.

[0079] It can be understood that when the outdoor unit 1 is installed in the installation grid 9, the air outlet grid of the outdoor unit 1 is located between the air outlet 11 of the outdoor unit 1 and the installation grid 9, in order to further improve the heat dissipation effect, the controller controls the air outlet grid piece 8 of the air outlet grid to rotate and be perpendicular to the direction of the air outlet 11, at this time, the air outlet grid piece 8 forms a horizontal wind deflector structure between the air outlet 11 of the outdoor unit 1 and the installation grid 9, and further forms a horizontal air duct structure (as shown in Figure 5 Thus, the hot air blown out of the air outlet 11 is directly guided to the outside of the installation grid 9 through the horizontal air duct structure, avoiding the outgoing air flow from escaping into the installation grid 9, that is, avoiding the temperature in the installation grid 9 from continuously rising, so that the heat of the outdoor unit 1 can be timely discharged to the outside of the installation grid 9, and further improving the heat dissipation effect of the outdoor unit 1.

[0080] Further, the second set condition includes that the current condenser temperature is higher than the outdoor environment temperature, and the temperature difference between the current condenser temperature and the outdoor environment temperature is greater than a second set temperature difference.

[0081] For example, the second set condition includes that the current condenser temperature is higher than the outdoor environment temperature, and the temperature difference between the current condenser temperature and the outdoor environment temperature is greater than 5℃, and the second set time is two hours.

[0082] It should be pointed out that the second set temperature difference and the second set time are both preset values, and the above parameters can be selected according to the environment where the air conditioner is located and the use requirements of the user, and the specific values of the second set temperature difference and the second set time are not specially limited in the application.

[0083] According to some embodiments of the application, after the step of adjusting the rotating direction of the air outlet grid piece 8 to be perpendicular to the air outlet 11, the cooling control method of the air conditioner outdoor unit further includes:

[0084] In the case that the rotating direction of the air outlet grille 8 is adjusted to be perpendicular to the air outlet 11 and lasts for at least a third set time length, and the condenser temperature and the outdoor environment temperature satisfy a third set condition, the control increases the superheat degree of the indoor unit 2 of the air conditioner.

[0085] In the present embodiment, when the spraying device continuously operates for a second set time length, and the rotating direction of the air outlet grille 8 is adjusted to be perpendicular to the air outlet 11 and lasts for at least a third set time length, if the condenser temperature and the outdoor environment temperature satisfy a third set condition, it is proved that the condenser temperature of the outdoor unit 1 is still at a high temperature level and fails to reach a normal temperature level, at this time, the outdoor unit 1 still has a high heat dissipation demand, at this time, in order to realize further heat dissipation of the outdoor unit 1, the controller controls the adjustment of the superheat degree of the indoor unit 2, reduces the outlet air temperature of the outdoor unit 1 by increasing the superheat degree, and further avoids the temperature of the outdoor unit 1 from being too high to affect normal refrigeration.

[0086] Further, the third set condition includes that the current condenser temperature is higher than the outdoor environment temperature, and the temperature difference between the current condenser temperature and the outdoor environment temperature is greater than a third set temperature difference.

[0087] For example, the third set condition includes that the current condenser temperature is higher than the outdoor environment temperature, and the temperature difference between the current condenser temperature and the outdoor environment temperature is greater than 5℃.

[0088] According to some specific embodiments of the present application, the step of controlling to increase the superheat degree of the indoor unit 2 of the air conditioner specifically includes:

[0089] According to the interval range of the temperature difference between the condenser temperature and the outdoor environment temperature, the superheat degree of the indoor unit 2 is determined and adjusted.

[0090] Further, in one specific embodiment, the step of determining and adjusting the superheat degree of the indoor unit 2 according to the interval range of the temperature difference between the condenser temperature and the outdoor environment temperature specifically includes:

[0091] In the case that the temperature difference between the condenser temperature and the outdoor environment temperature is in a first temperature difference range, the superheat degree of the indoor unit 2 is controlled to increase to a first superheat degree;

[0092] In the case that the temperature difference between the condenser temperature and the outdoor environment temperature is in a second temperature difference range, the superheat degree of the indoor unit 2 is controlled to increase to a second superheat degree;

[0093] In the case that the temperature difference between the condenser temperature and the outdoor environment temperature is in a third temperature difference range, the superheat degree of the indoor unit 2 is controlled to increase to a limit superheat degree.

[0094] Wherein, the first temperature difference range is smaller than the second temperature difference range, the second temperature difference range is smaller than the third temperature difference range, and the first superheat degree is smaller than the second superheat degree, and the second superheat degree is smaller than the limit superheat degree.

[0095] Thus, when the temperature difference between the condenser temperature and the outdoor environment temperature is in different interval ranges, it proves that the heat dissipation requirement of the current outdoor unit 1 is also different, that is, the higher the temperature difference, the higher the heat dissipation requirement of the outdoor unit 1, at this time, in order to match the heat dissipation requirement of the current outdoor unit 1, the controller needs to increase the superheat degree of the indoor unit 2 to a set level, for example, the first superheat degree matched with the first temperature difference range, the second superheat degree matched with the second temperature difference range, and the limit superheat degree matched with the third temperature difference range.

[0096] It can be understood that the increase of the superheat degree has a limit value, that is, the limit superheat degree, when the superheat degree reaches the limit superheat degree, the superheat degree is no longer increased.

[0097] The cooling control device of the outdoor unit of the air conditioner provided by the present application is described below, and the cooling control device of the outdoor unit of the air conditioner described below can be correspondingly referred to the cooling control method of the outdoor unit of the air conditioner described above.

[0102] Wherein, the cooling control device is connected with the outdoor unit 1 and the indoor unit 2 respectively, and the spraying device is arranged in the outdoor unit 1, and the spraying device includes a spraying head 3 arranged in the interior of the outdoor unit 1 and a branch pipe 4 connected to a drain pipe 7 of the indoor unit 2, and the branch pipe 4 is configured to transport the condensate water of the indoor unit 2 to the spraying head 3.

[0103] As​Figure 3 As shown, according to some embodiments of the present invention, the spraying device further includes a water pump 5 and a drain valve 6 disposed on the branch pipe 4.

[0104] like Figure 4 and Figure 5 As shown, according to some embodiments of the present invention, the outdoor fan 12 of the outdoor unit 1 is arranged opposite to the air outlet 11, and the air outlet 11 of the outdoor unit 1 is provided with an air outlet grille, which includes a plurality of air outlet gratings 8, and the air outlet gratings 8 are rotatably arranged relative to the air outlet 11.

[0105] It is understandable that, in order to further dissipate heat from the outdoor unit 1, the rotation direction of the air outlet grille 8 can be adjusted to be perpendicular to the air outlet 11, thereby using the air outlet grille 8 to form an air guide plate, directly guiding the hot air flowing out of the air outlet 11 to the outside of the grille. At this time, the air outlet grille 8 achieves shielding and sealing in the direction parallel to the air outlet 11, that is, preventing the air from the air outlet 11 from escaping into the mounting grille 9 in the direction parallel to the air outlet 11.

[0106] Furthermore, the aforementioned air outlet grille 8 can be connected to the drive end of a drive motor (not shown in the figure). In this way, the drive motor drives the air outlet grille 8 to rotate relative to the air outlet 11 to adjust its air guiding direction. The drive motor is also connected to the aforementioned cooling control device, so that it drives the air outlet grille 8 to rotate after receiving the instruction from the cooling control device.
