[0002] In the air conditioning equipment we use daily, when the air conditioner is in cooling mode, the evaporator starts to work to lower the indoor temperature. At this time, water vapor in the air will form condensate on the surface of the evaporator. Since the temperature of the condensate is lower than the indoor ambient temperature, the condensate has a certain amount of cooling capacity. If the condensate is drained directly at this time, some cooling capacity will be wasted. Therefore, it is necessary to recover the cooling capacity of the condensate to improve the energy efficiency of the air conditioner. Summary of the Invention

Detailed Implementation

[0034] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0035] The control method of the air conditioning equipment according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0036] refer to Figure 1 This is a schematic diagram of the air conditioning equipment structure provided in an embodiment of the present invention.

[0037] The air conditioning equipment includes an indoor heat exchanger 1, an outdoor heat exchanger 2, and a water pump 3. A water receiving tank 11 is provided below the indoor heat exchanger 1, and a water distribution tank 21 is provided on the top of the outdoor heat exchanger 2.

[0038] Specifically, the air conditioning unit uses compressor 4 to change the refrigerant in the liquid tank 5 from a gaseous state to a high-temperature, high-pressure gaseous state, providing the necessary conditions for the subsequent condensation process. The indoor heat exchanger 1 of the air conditioning unit is usually an evaporator, located indoors. When the high-temperature, high-pressure gaseous refrigerant enters the indoor heat exchanger 2, due to the decrease in temperature and pressure, the refrigerant begins to liquefy and releases a large amount of heat. During this process, the liquid refrigerant absorbs heat from the surrounding air and evaporates again, realizing the transformation from liquid to gas. The indoor heat exchanger 2 achieves the cooling of the indoor air by continuously circulating this process. A water collection tank 11 is provided below the indoor heat exchanger 1. Water vapor in the air comes into contact with the lower-temperature surface of the indoor heat exchanger 2, and condensation occurs, flowing into the water collection tank 11. The water collection tank 11 is connected to the outdoor heat exchanger 2 through a water pump 3 and a drain pipe.

[0039] It should be noted that the air conditioning unit may also be equipped with a four-way valve 6, used to switch the airflow direction between cooling and heating modes. The air conditioning unit may also be equipped with a throttling valve 7, connected to the indoor heat exchanger 1, which throttles the refrigerant, allowing the refrigerant saturated liquid at normal temperature and high pressure to become a low-temperature and low-pressure refrigerant liquid when flowing through the throttling valve 7, thus ensuring the stability of the air conditioning unit's refrigeration system.

[0040] refer to Figure 2 This is a schematic diagram of the structure of the outdoor heat exchanger 2 and the water distribution tank 21 provided in an embodiment of the present invention.

[0041] As an optional embodiment, the water distribution trough 21 is distributed along the top structure of the outer shell of the outdoor heat exchanger 2, and the bottom of the water distribution trough 21 is provided with a plurality of through holes 211 extending in the vertical direction.

[0042] Specifically, the outer shell structure of the outdoor heat exchanger 2 may be irregular, such as a cuboid structure with rounded corners. The water distribution channel 21 is distributed along the top structure of the outer shell of the outdoor heat exchanger 2 so that the water distribution channel 21 can fit the shape of the top of the outer shell of the outdoor heat exchanger 2. The bottom of the water distribution channel 21 is provided with multiple through holes 211 extending vertically. The through holes 211 can be evenly distributed on the water distribution channel 21, so that the condensate flowing into the water distribution channel 21 can be evenly and quickly flowed onto the outdoor heat exchanger 2.

[0043] It should be noted that the design of the water distribution tank 21 and the through hole 211 can also be considered to prevent debris and dust from entering the outdoor heat exchanger 2. By reasonably setting the size and position of the through hole 211, larger debris and dust particles can be limited from entering the water distribution tank 21 and the interior of the outdoor heat exchanger 2, thereby maintaining the cleanliness and efficient operation of the outdoor heat exchanger 2.

[0044] refer to Figure 3 This is a flowchart of a control method for an air conditioning device provided in an embodiment of the present invention.

[0045] Step S301: Obtain the water level information of the condensate in the water receiving tank.

[0046] Specifically, the water level information includes a first water level, a second water level, and a third water level. This water level information can be obtained by installing water level sensors in the receiving tank. The receiving tank can contain a first water level sensor and a second water level sensor. The first water level sensor monitors the critical value between the first and second water levels, and the second water level sensor monitors the critical value between the second and third water levels. Alternatively, water level information can be determined by setting a float switch in the receiving tank. When the water level rises abnormally and reaches a set height, the float switch will send a signal to the control system.

[0047] Step S302: Control the water pump according to the water level information. The water pump is used to pump the condensate to the water distribution tank so that the condensate is sprayed onto the outer shell of the outdoor heat exchanger through the water distribution tank.

[0048] Specifically, based on the different condensate levels in the receiving tank, the water pump is activated in different modes to adjust the water level. The water pump draws the condensate from the receiving tank to the distribution tank, and then sprays the condensate onto the outer casing of the outdoor heat exchanger, effectively improving the efficiency of condensate cooling recovery and thus enhancing the air conditioner's energy efficiency.

[0049] As an optional embodiment, controlling the water pump based on water level information includes: controlling the water pump to be in a closed state when it is determined from the water level information that the condensate is at a first water level.

[0050] Specifically, when the water level in the receiving tank is at the first water level, the receiving tank is in a water shortage state, and the control system sets the water pump to the off state to ensure that pumping is not started when the water in the receiving tank is insufficient.

[0051] As an optional embodiment, controlling the water pump based on water level information includes: controlling the water pump to operate in a first control mode when it is determined from the water level information that the condensate is at a second water level.

[0052] Specifically, when the water level in the receiving tank is at the second position, the receiving tank is in a low water level state, and the control system sets the water pump to the first control mode. The water pump operates in the first control mode to discharge the condensate in the receiving tank to the distribution tank.

[0053] refer to Figure 4 This is a schematic diagram of an embodiment of the first control mode provided by the present invention.

[0054] As an optional embodiment, the first control mode includes: after controlling the water pump to run for a first preset time with a first preset voltage, re-acquiring the current water level information of the condensate in the water receiving tank; if it is determined according to the current water level information that the condensate is still at the second water level, then updating the first preset voltage according to a first preset step size, and repeating the above steps according to the updated first preset voltage until the condensate is no longer at the second water level.

[0055] Specifically, Figure 4 (a) is a schematic diagram of the water level. Figure 4 (b) is a schematic diagram showing the relationship between the pump start-up time and voltage.

[0056] When the water level in the receiving tank is at the second water level, the control activates the first control mode, and the water pump starts running at the first preset voltage for the first preset time to discharge the condensate in the receiving tank to the distribution tank. Furthermore, after the running time reaches the first preset time, the water level of the condensate in the receiving tank is re-acquired. If the water level of the condensate in the receiving tank is still at the second water level, the first preset voltage is updated according to the first preset step size to obtain the updated first preset voltage. The above operation is repeated according to the updated first preset voltage until the condensate in the receiving tank is no longer at the second water level, at which point other control modes are switched.

[0057] It should be noted that determining the step size typically requires consideration of multiple factors, including the performance characteristics of the water pump, the condensate treatment requirements, and the response speed of the control system. In practical applications, the optimal step size value can be found through experiments or simulations. By setting a reasonable preset step size, the control system can handle condensate more efficiently.

[0058] refer to Figure 5 This is a schematic diagram of another embodiment of the first control mode provided by the present invention.

[0059] As an optional embodiment, the first control mode includes: controlling the water pump to start and stop at a preset frequency until the condensate is not at the second water level.

[0060] Specifically, Figure 5 (a) is a schematic diagram of the water level. Figure 5 (b) is a schematic diagram showing the relationship between the pump start-up time and voltage.

[0061] The first control mode also includes controlling the start and stop of the water pump via a preset frequency until the condensate in the receiving tank is no longer at the second water level, at which point other control modes are switched. The preset frequency represents the cycle rate of the start and stop. In a complete cycle, the water pump can first stop running for a preset time, then start running for a preset time, and then stop running for a preset time to wait for the start of the next cycle.

[0062] For example, when the water level in the receiving tank is at the second water level, the control activates the first control mode. The water pump first stops running for a preset time Δt1, and then starts running for another preset time Δt2. During the water pump's operation, the water level of the condensate in the receiving tank is obtained in real time. If the water level of the condensate in the receiving tank is still at the second water level, the above operation is repeated until the condensate in the receiving tank is no longer at the second water level, at which point other control modes are switched.

[0063] As an optional embodiment, controlling the water pump based on water level information includes: controlling the water pump to operate in a second control mode when it is determined from the water level information that the condensate is at a third water level.

[0064] Specifically, when the water level in the receiving tank is at the third water level, the receiving tank is in a high water level state. The control system sets the water pump to the second control mode, and the water pump operates in the second control mode to discharge the condensate in the receiving tank to the distribution tank.

[0065] refer to Figure 6 This is a schematic diagram of an embodiment of the second control mode provided by the present invention.

[0066] As an optional embodiment, the second control mode includes: after controlling the water pump to run for a second preset time with a second preset voltage, re-acquiring the current water level information of the condensate in the water receiving tank; if it is determined according to the current water level information that the condensate is still at the third water level, then updating the second preset voltage according to the second preset step size, and repeating the above steps according to the updated second preset voltage until the condensate is no longer at the third water level.

[0067] Specifically, Figure 6 (a) is a schematic diagram of the water level. Figure 6 (b) is a schematic diagram showing the relationship between the pump start-up time and voltage.

[0068] When the water level in the receiving tank is at the third water level, the control activates the second control mode. The water pump starts running at the second preset voltage for the second preset duration, draining the condensate in the receiving tank to the distribution tank. Furthermore, after the running time reaches the second preset duration, the current condensate level in the receiving tank is re-acquired. If the current condensate level in the receiving tank is still at the third water level, the second preset voltage is updated according to the second preset step size to obtain the updated second preset voltage. The above operation is repeated according to the updated second preset voltage until the condensate in the receiving tank is no longer at the third water level, at which point other control modes are switched.

[0069] It should be noted that when the running time reaches the second preset time, the water level of the condensate in the water tank is retrieved again. If the water level of the condensate in the water tank is still at the third level, it indicates that the air conditioning equipment may be malfunctioning. At the same time, the compressor needs to be shut down to stop the air conditioning from running, to prevent the indoor heat exchanger from continuing to produce condensate, which could cause the condensate to overflow and damage the equipment.

[0070] It should be noted that since the third water level is generally a high water level, the second preset voltage generally needs to be higher than the first preset voltage so that the water pump can discharge the condensate in the receiving tank to the distribution tank more quickly, thus avoiding waste of cooling capacity.

[0071] refer to Figure 7 This is a schematic diagram of another embodiment of the second control mode provided by the present invention.

[0072] As an optional embodiment, the second control mode includes: controlling the water pump to be in operation until the condensate is not at the third water level.

[0073] Specifically, Figure 7 (a) is a schematic diagram of the water level. Figure 7 (b) is a schematic diagram showing the relationship between the pump start-up time and voltage.

[0074] When the water level in the water tank reaches the third level, the control activates the second control mode, and the water pump keeps running. At the same time, the water level of the condensate in the water tank is acquired in real time until the water level of the condensate in the water tank is no longer at the third level, at which point other control modes are switched.

[0075] refer to Figure 8 This is a logic diagram of the control method for an air conditioning device provided in an embodiment of the present invention.

[0076] Specifically, after the air conditioning equipment starts running, it begins to detect the water level information in the water tank and controls the operation mode of the water pump according to the water level information: when the water level information is the first water level, the water pump is kept in the off state; when the water level information is the second water level, the water pump is controlled to operate in the first control mode; when the water level information is the third water level, the water pump is controlled to operate in the second control mode.

[0077] According to the control method of the air conditioning equipment of the present invention, by setting a water distribution tank on the top of the outdoor heat exchanger and dynamically controlling the working mode of the water pump according to the water level of the condensate in the water distribution tank, the condensate can be discharged to the outdoor heat exchanger more quickly, effectively improving the recovery efficiency of the condensate cooling capacity and further improving the energy efficiency of the air conditioner.

[0078] refer to Figure 9 This is a schematic diagram of the control device for an air conditioning system provided in an embodiment of the present invention.

[0080] In some embodiments of the present invention, the water distribution channels are distributed along the top structure of the outer shell of the outdoor heat exchanger, and the bottom of the water distribution channels is provided with a plurality of through holes extending in the vertical direction.

[0083] In some embodiments of the present invention, the control module 920 is specifically used to: control the water pump to be in a closed state when it is determined from the water level information that the condensate is at a first water level.

[0084] In some embodiments of the present invention, the control module 920 is further configured to: control the water pump to operate in a first control mode when it is determined from the water level information that the condensate is at a second water level.

[0086] In some embodiments of the present invention, the first control mode further includes: controlling the water pump to start and stop at a preset frequency until the condensate is not at the second water level.

[0087] In some embodiments of the present invention, the control module 920 is further configured to: control the water pump to operate in a second control mode when it is determined from the water level information that the condensate is at the third water level.

[0088] In some embodiments of the present invention, the second control mode includes: after controlling the water pump to run for a second preset time with a second preset voltage, re-acquiring the current water level information of the condensate in the water receiving tank; if it is determined according to the current water level information that the condensate is still at the third water level, then updating the second preset voltage according to the second preset step size, and repeating the above steps according to the updated second preset voltage until the condensate is no longer at the third water level.

[0089] In some embodiments of the present invention, the second control mode further includes: controlling the water pump to be in operation until the condensate is not at the third water level.
