Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of air conditioning, and in particular to a method and device for treating condensed water of air conditioning equipment, and air conditioning equipment. Background Art
[0002] Window air conditioners collect and consume condensed water, eliminating the need to discharge condensed water. For cooling-only air conditioners, only the condensed water on the evaporator side needs to be collected for reuse. For heating and cooling air conditioners, the condensed water in cooling mode is on the indoor side, and the condensed water in heating mode is on the outdoor side. The condensed water consumption needs to be concentrated on the indoor side or the outdoor side for reuse. The reuse of condensed water can improve the efficiency of the heat exchanger and solve the problem of condensed water discharge.
[0003] When the air conditioner is heating in a cold environment, the outdoor fan blades do not pump water sufficiently, water splashes, and the fan blades are easily damaged by freezing. The pump of the outdoor unit may also be blocked due to freezing during spraying. Defrosting is performed through the refrigerant pipe connected to the outdoor heat exchanger. In an ultra-low temperature environment, ice cubes in some parts of the water tank used to collect outdoor condensed water are difficult to melt, resulting in incomplete defrosting. Ice cubes will occupy the volume of the water tank, increasing the risk of defrosting water overflow. Summary of the invention

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein.

For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices. The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.
[0031] An embodiment of the present invention provides a method for treating condensed water of an air-conditioning device, wherein the air-conditioning device may be an integrated window air-conditioning device or a split air-conditioning device having an indoor unit and an outdoor unit. Figure 1 The schematic diagram of the structure of an air-conditioning device to which the condensed water treatment method of the air-conditioning device provided by the embodiment of the present invention is applied is shown in FIG. Figure 1 As shown, the air conditioning equipment at least includes a refrigerant circulation system 100 , an air conditioning control system 200 and a condensed water treatment system 300 .
[0032] Figure 2 for Figure 1 Schematic diagram of the layout of the refrigerant circulation system and condensate treatment system. Figure 3 Schematic diagram of the connection of refrigerant pipes in the refrigerant circulation system of an embodiment of the present invention. Figure 2 and Figure 3As shown, the refrigerant circulation system 100 includes a circulation loop formed by connecting main components such as an outdoor heat exchanger 110, an indoor heat exchanger 120, a compressor 130, and a throttling component, and the refrigerant circulates in the system under the action of the compressor 130. The refrigerant circulation system 100 also includes a refrigerant pipe 140 disposed in the first water storage tank 310 and connected to the outdoor heat exchanger 110. In some embodiments, a portion of the outdoor heat exchanger 110 extends into the first water storage tank 310 and spirals therein, forming the refrigerant pipe 140.
[0033] Figure 3 As shown, in some embodiments of the present invention, the compressor 130, the outdoor heat exchanger 110, the throttling component, the refrigerant pipe 140 and the indoor heat exchanger 120 are connected in sequence. When the air-conditioning device is in heating operation, the indoor heat exchanger 120 releases heat as a condenser, and the refrigerant pipe 140 can also release heat. At this time, the refrigerant pipe 140 can defrost the condensed water in the ice state in the first water storage tank 310. In other embodiments, the number of throttling components can be two, one of which is arranged between the refrigerant pipe 140 and the outdoor heat exchanger 110, and the other throttling component is arranged between the refrigerant pipe 140 and the indoor heat exchanger 120. When the air conditioner is in heating operation, the indoor heat exchanger 120 releases heat as a condenser. If the refrigerant pipe 140 is required to defrost the condensed water in the ice state in the first water storage tank 310, the throttling component between the indoor heat exchanger 120 and the refrigerant pipe 140 can be controlled not to throttle, and only the throttling component between the outdoor heat exchanger 110 and the refrigerant pipe 140 can be controlled to throttle, so that the temperature of the refrigerant flowing through the refrigerant pipe 140 is higher. If it is necessary to increase the heat release capacity of the indoor heat exchanger 120, the throttling component between the indoor heat exchanger 120 and the refrigerant pipe 140 can be controlled to throttle, and only the throttling component between the outdoor heat exchanger 110 and the refrigerant pipe 140 can be controlled not to throttle. When the air conditioning equipment is in defrosting operation, the outdoor heat exchanger 110 is controlled to release heat as a condenser, the throttling component between the outdoor heat exchanger 110 and the refrigerant pipe 140 is not throttling, and the throttling component between the indoor heat exchanger 120 and the refrigerant pipe 140 is throttling, so that the refrigerant pipe 140 can defrost the condensed water in the ice state in the first water storage tank 310.
[0034] like Figure 2 As shown, the condensate treatment system 300 is used to collect and treat the condensate generated by the refrigerant circulation system 100 during the refrigerant circulation process. The condensate treatment system 300 at least includes: a first water storage tank 310 for collecting the condensate generated by the outdoor heat exchanger 110, and a second water storage tank 320 for collecting the condensate generated by the indoor heat exchanger 120.
[0035] The condensate treatment system 300 may further include a first drainage device 330, a second drainage device 340 and an indoor humidification device 360. The first drainage device 330 is used to transport the condensate accumulated in the first water storage tank 310 to the second water storage tank 320, and the second drainage device 340 is used to atomize or gasify the condensate accumulated in the second water storage tank 320 and then discharge it to the outdoor environment to avoid direct discharge of the condensate causing the surrounding of the air conditioning equipment to be corroded by the condensate. The indoor humidification device 360 is used to discharge the condensate accumulated in the second water storage tank 320 to the surface of the indoor heat exchanger 120.
[0036] The air circulation system 400 of the air conditioning equipment at least includes: an outdoor fan 410 corresponding to the outdoor heat exchanger 110, and an indoor fan 420 corresponding to the indoor heat exchanger 120. The air conditioning control system 200 is used to control the refrigerant circulation system 100, the condensed water treatment system 300 and the air circulation system 400 of the air conditioning equipment.
[0037] like Figure 2 As shown, a first water level switch 350 may be provided in the second water storage tank 320, and a second water level switch 370 may be provided in the first water storage tank 310. The first water level switch 350 is used to detect the water level in the second water storage tank 320 and provide it to the air conditioning control system 200; the second water level switch 370 is used to detect the water level in the first water storage tank 310 and provide it to the air conditioning control system 200.
[0038] like Figure 2 As shown, the first drainage device 330 may include a drainage pipeline 330a and a first pump 330b connected to the drainage pipeline 330a, one end of the drainage pipeline 330a is disposed in the second water storage tank 320, and the other end of the drainage pipeline 330a is disposed in the first water storage tank 310. The first drainage device 330 transports the condensed water accumulated in the first water storage tank 310 to the second water storage tank 320 by controlling the start and stop of the first pump 330b.
[0039] like Figure 2 As shown, the second drainage device 340 may include a spray head 340a, a spray pipe 340b and a second water pump 340c connected to the spray pipe 340b, which are connected in sequence. Part of the spray pipe 340b and the spray head 340a are located outdoors, and one end of the spray pipe 340b is arranged in the second water storage tank 320. By controlling the start and stop of the second water pump 340c, the condensed water in the second water storage tank 320 is atomized or vaporized and then discharged to the outdoor environment.
[0040] like Figure 2As shown, the indoor humidifying device 360 may include a third water pump 360a and a humidifying pipeline 360b connected in sequence. The third water pump 360a is arranged in the second water storage tank 320, and the humidifying pipeline 360b is used to discharge condensed water extracted from the second water storage tank 320 by the third water pump 360a to the surface of the indoor heat exchanger 120, so as to humidify the indoor environment.
[0041] Figure 4 A schematic diagram of a process for treating condensed water of an air conditioner provided by an embodiment of the present invention is shown in FIG. Figure 4 As shown, the embodiment of the present invention provides a method for treating condensed water of an air conditioner, Figures 1 to 3 As shown, the condensate treatment method of the air conditioning equipment includes the following steps S401 to S403.
[0042] S401: In the heating condition of the air conditioning equipment, monitoring the state of condensed water in the first water storage tank 310;
[0043] S402 : If the state of the condensed water in the first water storage tank 310 satisfies the first defrosting condition, the condensed water in the first water storage tank 310 is defrosted based on the refrigerant pipe 140 .
[0044] After the air-conditioning device enters the heating condition, it is triggered to start monitoring whether the state of condensed water in the first water storage tank 310 meets the first ice-melting condition.
[0045] In some embodiments, an ice detection device 380 for detecting whether the condensed water is frozen may be provided in the first water storage tank 310, wherein the installation position of the ice detection device 380 is far away from the refrigerant pipe 140 and is located at a position where the refrigerant pipe 140 is difficult to heat, so as to more accurately detect whether the condensed water in the first water storage tank 310 is frozen. The ice detection device 380 may include a capacitive probe or a resistive probe provided in the first water storage tank 310. The electrical parameter measurement values obtained by the ice detection device 380 when detecting frozen condensed water and liquid condensed water will be different, that is, the measured resistance value or capacitance value will be different. Therefore, the electrical parameter measurement value of the ice detection device 380 that characterizes the state of condensed water in the first water tank 310 is obtained; if the electrical parameter measurement value is within the first parameter range, it characterizes that the condensed water in the first water tank 310 is not frozen, and it is determined that the state of the condensed water in the first water tank 310 does not meet the first defrosting condition; if the electrical parameter measurement value is within the second parameter range, it characterizes that the condensed water in the first water tank 310 is at least partially frozen, and it is determined that the state of the condensed water in the first water tank 310 meets the first defrosting condition, wherein the first parameter range is the electrical parameter range measured for liquid condensed water, and the second parameter range is the electrical parameter range measured for frozen condensed water.
[0046] In other embodiments, the temperature of the condensed water in the first water storage tank 310 can be detected by a temperature sensor (not shown), and whether the state of the condensed water in the first water storage tank 310 meets the first deicing condition can be determined according to the temperature of the condensed water; if the temperature of the cold condensed water in the first water storage tank 310 is within the first temperature range, it indicates that the condensed water in the first water storage tank 310 is at least partially frozen, and it is determined that the state of the condensed water in the first water storage tank 310 meets the first deicing condition; if the temperature of the condensed water is within the second temperature range, it indicates that the condensed water in the first water storage tank 310 is not frozen, and it is determined that the state of the condensed water in the first water storage tank 310 does not meet the first deicing condition. The first temperature range and the second temperature range are determined by experiments, and the upper limit of the first temperature range is not greater than the lower limit of the second temperature range.
[0047] S403: If the time for defrosting the condensed water in the first water tank 310 based on the refrigerant pipe 140 reaches a first preset defrosting time, and the state of the condensed water in the first water tank 310 meets a second defrosting condition, turn on the first electric heating component to assist in defrosting the condensed water in the first water tank 310, wherein the first defrosting condition and the second defrosting condition indicate that the condensed water in the first water tank 310 is at least partially frozen.
[0048] It should be noted that in a low-temperature outdoor environment, when the residual water in the first water storage tank 310 cannot be drained away in time and remains, it is necessary to provide sufficient heat to maintain the liquid state of the residual condensed water in the first water storage tank 310. Figure 3 As shown, in the heating condition of the air-conditioning equipment, the indoor heat exchanger 120 is a high-temperature device. The refrigerant flowing out of the indoor heat exchanger 120 first passes through the refrigerant pipe 140, and then passes through the throttling component for throttling to ensure that the refrigerant pipe 140 is a heat pipe. After verification, when the outdoor pipe diameter temperature is -8.3°C, the temperature of the refrigerant pipe 140 is about 22°C, which can maintain the condensed water in the first water storage tank 310 in a liquid state. The extended refrigerant pipe 140 can play a role in keeping the space in the first water storage tank 310 warm, so as to maintain the liquid state of the residual condensed water in the first water storage tank 310. As the temperature of the outdoor environment is lower, the normal heating operation of the air-conditioning equipment is not enough to keep the temperature of the refrigerant pipe 140 in a liquid state of the condensed water. Therefore, when the state of the condensed water in the first water storage tank 310 meets the first deicing condition, it is necessary to start the deicing process based on the refrigerant pipe 140 to deice the condensed water in the first water storage tank 310 based on the refrigerant pipe 140.
[0049] Based on the refrigerant pipe 140, it is necessary to adjust one or more operating parameters of the air conditioning equipment to increase the temperature of the refrigerant pipe 140, wherein adjusting one or more operating parameters of the air conditioning equipment may include: increasing the compressor frequency, reducing the speed of the indoor fan 420, reducing the speed of the outdoor fan 410, increasing the opening of the throttling component, etc., or a combination of at least two methods to increase the temperature of the refrigerant pipe 140, so that the refrigerant pipe 140 can heat the space in the first water storage tank 310, and realize the thawing of the frozen condensed water in the first water storage tank 310 at an ultra-low outdoor temperature. However, on the one hand, adjusting the operating parameters of the air conditioning equipment will affect the heating performance of the air conditioner and reduce the user comfort, so the high temperature state of the refrigerant pipe 140 cannot be maintained for a long time. On the other hand, when the outdoor ambient temperature is low and the residual water in the first water storage tank 310 cannot be drained away in time and remains, the refrigerant pipe 140 is in a relatively low temperature state and partially freezes. The condensed water close to the refrigerant pipe 140 is in liquid state, and the condensed water away from the refrigerant pipe 140 is in an ice state. The liquid condensed water close to the refrigerant pipe 140 is gradually heated and evaporated and dried up, resulting in Figure 5 The phenomenon of residual ice shown in the figure is that due to evaporation and drying up, the area near the refrigerant pipe 140 is air, and the condensed water far away from the refrigerant pipe 140 is still in a frozen state. At this time, because the heat transfer medium between the refrigerant pipe 140 and the residual ice is air, the residual ice cannot be melted even if the temperature of the refrigerant pipe 140 is increased. The residual ice will occupy the space in the first water storage tank 310, reducing the actual volume of the first water storage tank 310. Although the temperature of the refrigerant pipe 140 is increased before the above-mentioned evaporation and drying up phenomenon occurs, entering a high temperature state can melt the residual ice far away from the refrigerant pipe 140, but since the volume of the ice cubes decreases during the melting process, it is easy to Figure 6 When the ice residue is thick, it may cause condensed water to overflow. In addition, ice residue is easily left in the pipe fixture, water level switch, water pump and other parts in the first water storage tank 310, resulting in failure to drain water normally.
[0050] like Figure 5 , Figure 6 As shown, in order to solve the impact of thawing condensed water based on the refrigerant pipe 140 on user comfort and solve the problem of residual ice and ice debris in the first water storage tank 310, the air conditioning equipment also includes at least a first electric heating component 400 for auxiliary heating of condensed water in the first water storage tank 310. The first electric heating component 400 may include: a first heating pipe disposed outside the first water storage tank 310 and in contact with the bottom plate of the first water storage tank 310 and / or a second heating pipe (not shown) disposed in the first water storage tank 310.
[0051] In some embodiments, the second defrosting condition is the same as or similar to the first defrosting condition, that is, the electrical parameter measurement value of the state of condensed water in the first water tank 310 detected by the ice detection device 380 is obtained; if the electrical parameter measurement value is within the first parameter range, it indicates that the condensed water in the first water tank 310 is completely defrosted based on the refrigerant pipe 140, and it is determined that the state of the condensed water in the first water tank 310 does not meet the second defrosting condition; if the electrical parameter measurement value is within the second parameter range, it indicates that the condensed water in the first water tank 310 is not completely defrosted based on the refrigerant pipe 140, and there is residual ice, and the residual There is air between the ice and the refrigerant pipe 140. Increasing the temperature of the refrigerant pipe 140 can no longer melt the residual ice. This abnormality will cause the residual ice to grow. In the worst case, the water will overflow from the first water tank 310. Therefore, after starting the defrosting process based on the refrigerant pipe 140 to defrost the condensed water in the first water tank 310 based on the refrigerant pipe 140, it is necessary to determine whether the state of the condensed water in the first water tank 310 meets the second defrosting condition, wherein the first parameter range is the electrical parameter range measured for liquid condensed water, and the second parameter range is the electrical parameter range measured for frozen condensed water.
[0052] In some embodiments, after turning on the first electric heating component 400, the method may further include: timing the operation time of the first electric heating component 400; if the operation time of the first electric heating component 400 reaches the second preset ice-melting time, the first electric heating component 400 is turned off. The second preset ice-melting time is greater than or equal to the first preset ice-melting time to ensure that the residual ice can be completely melted. In other embodiments, after turning on the first electric heating component 400, the method may further include: monitoring the state of condensed water in the first water storage tank 310; if the state of condensed water in the first water storage tank 310 changes to not satisfy the second ice-melting condition, the first electric heating component 400 is turned off. Of course, the above two embodiments may be used in combination or separately. It should be noted that the first preset ice-melting time is related to the arrangement of the refrigerant pipe 140, and the second preset ice-melting time is related to the power, arrangement, etc. of the first electric heating component 400. Therefore, the first preset ice-melting time and the second ice-melting time can be pre-determined, and the specific values are not limited here.
[0053] In some embodiments, turning on the first electric heating component 400 to assist in defrosting the condensed water in the first water storage tank 310 may include: while turning on the first electric heating component 400, restoring the parameter value of the operating parameter of the air-conditioning device, so that the air-conditioning device is in a normal heating process when the first electric heating component 400 is working, reducing the duration of the impact of the defrosting process based on the refrigerant pipe 140 on the heating performance. In other embodiments, it is also possible to restore the parameter value of the operating parameter of the air-conditioning device when the first electric heating component 400 is turned off, so that the defrosting process based on the refrigerant pipe 140 is still in progress when the first electric heating component 400 is working, achieving faster defrosting. It is understandable that restoring the parameter value of the operating parameter of the air-conditioning device may include: restoring the compressor frequency to the temperature difference between the current indoor ambient temperature and the set temperature, and the speed of the outdoor fan 410 and the speed of the indoor fan 420 are restored to the speed before the defrosting process based on the refrigerant pipe 140 is turned on or restored to the default speed.
[0054] In some embodiments, if the air-conditioning equipment further includes at least a second water tank 320 for collecting condensed water generated by its indoor heat exchanger 120, a first drainage device 330 for draining water from the first water tank 310 to the second water tank 320, and a second drainage device 340 for atomizing or vaporizing the condensed water in the second water tank 320 and discharging it to the outdoor environment, then, after defrosting the condensed water in the first water tank 310 based on the refrigerant pipe 140, it may also include: monitoring the water level in the first water tank 310 and the water level in the second water tank 320. It can be understood that the water level detected by the second water level switch 370 in the first water tank 310 is obtained, and it is determined whether the first water level upper limit is reached; the water level detected by the first water level switch 350 in the second water tank 320 is obtained, and it is determined whether the second water level upper limit is reached; if the water level in the first water tank 310 rises to the first water level upper limit, the first drainage device 330 is turned on so that the first drainage device 330 transports condensed water from the first water tank 310 to the second water tank 320; if the water level in the second water tank 320 rises to the second water level upper limit, the second drainage device 340 is turned on so that the second drainage device 340 atomizes or vaporizes the condensed water in the second water tank 320 and discharges it to the outdoor environment.
[0055] In some embodiments, after turning on the first drainage device 330 and the second drainage device 340, the following may also be included: when the operating time of the first drainage device 330 reaches a first drainage time threshold, the first drainage device 330 is turned off, wherein the first drainage time threshold is greater than the time required for emptying the first water storage tank 310 when it is full of water; when the operating time of the second drainage device 340 reaches a second drainage time threshold, the second drainage device 340 is turned off, wherein the second drainage time threshold is greater than the time required for emptying the second water storage tank 320 when it is full of water.
[0056] In other embodiments, after turning on the first drainage device 330 and the second drainage device 340, it may also include: when it is detected that the water level in the first water storage tank 310 drops to the lower limit of the second water level, closing the first drainage device 330; after detecting that the first drainage device 330 is closed and the water level in the second water storage tank 320 drops to the lower limit of the first water level, closing the second drainage device 340.
[0057] In other embodiments, the first electric heating component 400 and the refrigerant pipe 140 can also be controlled in linkage, and the first drainage device 330 can be turned off after a first delay period after the first electric heating component 400 is turned off, and the second drainage device 340 can be turned off after a second delay period, wherein the second delay period is greater than the first delay period.
[0058] In some embodiments, if the air-conditioning equipment receives an air-conditioning shutdown command under heating conditions, the water level in the second water tank 320 is obtained, which can be to obtain the water level detected by the second water level switch 370 in the second water tank 320, and determine whether the water level in the second water tank 320 reaches the first water level lower limit; if the first water level lower limit is reached, the second drainage device 340 is controlled to run for a preset pumping time and then shut down, so as to atomize or vaporize the remaining condensed water in the second water tank 320 and discharge it to the outdoor environment, wherein the preset pumping time can be the time required to evacuate the second water tank 320 when it is full of water.
[0059] In order to facilitate understanding of the condensed water treatment method for air conditioning equipment provided by an embodiment of the present invention, an execution logic for achieving complete ice melting at ultra-low outdoor temperatures is provided below:
[0060] A1: The air conditioning equipment enters the heating state, triggering the execution of step A2;
[0061] A2: monitoring whether the state of condensed water in the first water storage tank 310 meets the first ice-melting condition, and if so, triggering execution of step A3;
[0062] A3: thawing the condensed water in the first water storage tank 310 based on the refrigerant pipe 140, and starting the first timing and triggering to start monitoring the water level in the first water storage tank 310 and the water level in the second water storage tank 320, wherein when the duration of the first timing reaches A minutes, step A4 is triggered to be executed, when the water level in the first water storage tank 310 reaches the first water level upper limit, step A6 is executed, and when the water level in the second water storage tank 320 reaches the second water level upper limit, step A7 is executed;
[0063] A4: monitoring whether the state of condensed water in the first water storage tank 310 reaches the second ice-melting condition, and if so, triggering execution of step A5;
[0064] A5: Turn on the first electric heating assembly 400 to assist in defrosting the condensed water in the first water storage tank 310 and start the second timing. When the second timing reaches B minutes, return to step A2;
[0065] A6: Open the first drainage device 330 to drain water from the first water storage tank 310 to the second water storage tank 320, and start the third timer. When the duration of the third timer reaches C minutes, close the first drainage device 330;
[0066] A7: Open the second drainage device 340 to atomize or gasify the condensed water in the second water storage tank 320 and discharge it to the outdoor environment, and start the fourth timer. When the duration of the fourth timer reaches D minutes, close the second drainage device 340;
[0067] A8: If the air-conditioning equipment receives an air-conditioning shutdown command in the heating condition, the second pumping device 340 is turned on to atomize or vaporize the remaining condensed water in the second water storage tank 320 and discharge it to the outdoor environment until it is detected that the water level in the second water storage tank 320 has not triggered the first water level lower limit within E minutes, and then the second pumping device 340 is turned off.
[0068] In some embodiments, if the air-conditioning equipment also includes a second electric heating component (not shown) for heating the condensed water in the second water tank 320, but does not include an indoor humidifying device 360, then the condensed water processing method of the air-conditioning equipment may also include: if the air-conditioning equipment receives an air-conditioning shutdown command under a refrigeration condition or a dehumidification condition, obtaining the water level in the second water tank 320; if the water level in the second water tank 320 does not trigger the first water level lower limit within a preset observation time, turning on the second electric heating component, and controlling the second electric heating component to turn off after running for a preset drying time, so as to achieve heating and evaporation of the condensed water remaining in the second water tank 320, thereby avoiding the growth of bacteria and causing the water system to stink.
[0069] In other embodiments, the air-conditioning equipment also includes an indoor humidifying device 360 and a second electric heating component for heating the condensed water in the second water tank 320. Then, if the air-conditioning equipment receives an air-conditioning shutdown command under a cooling condition or a dehumidification condition, the water level in the second water tank 320 is obtained; if the water level in the second water tank 320 does not trigger the first water level lower limit within the preset observation time, it is detected whether the humidification function of the air-conditioning equipment is in the on state; if it is not in the on state, the second electric heating component is turned on, and the second electric heating component is controlled to turn off after running for a preset drying time; if it is in the on state, the second electric heating component does not need to be turned on, but the indoor humidifying device 360 is controlled according to the indoor environmental humidity, so that the indoor humidifying device 360 uses the remaining condensed water in the second water tank 320 to humidify the indoor environment. For example, when the indoor environment humidity is lower than the first humidity threshold, the indoor humidifying device 360 is turned on to extract the remaining condensed water in the second water storage tank 320 to humidify the indoor environment. When the indoor environment humidity is higher than the second humidity threshold, the indoor humidifying device 360 is turned off. The second humidity threshold is greater than the first humidity threshold.
[0070] It should be noted that, since there may be a lot of condensed water in the second water storage tank 320 when the air conditioner shutdown command is received, it cannot be dried quickly if it is directly dried by the second electric heating component, and electric energy is wasted. In some embodiments, if the air conditioner receives the air conditioner shutdown command in the cooling condition or the dehumidification condition, and the water level in the second water storage tank 320 is higher than the first water level lower limit, the second drainage device 340 is started to atomize the condensed water in the second water storage tank 320 and then discharge it to the outdoor environment; during the operation of the second drainage device 340, if the water level in the second water storage tank 320 does not trigger the first water level lower limit within the preset observation time, the second drainage device 340 is turned off. After the second drainage device 340 is turned off, the second electric heating component is turned on again to run for the preset drying time and then turned off to heat and evaporate the condensed water remaining in the second water storage tank 320. It should be noted that the second electric heating component and the first electric heating component 400 can be the same electric heating tube, or can be two electric heating tubes that are controlled separately.
[0071] In order to facilitate understanding of the condensate water treatment method for air conditioning equipment provided by the embodiment of the present invention, an execution logic is provided below to prevent the residual water in the second water storage tank 320 from generating odor or breeding bacteria:
[0072] B1: When the air conditioner is in cooling or dehumidification mode, if a shutdown command is received, step B2 is triggered;
[0073] B2 detects whether the water level in the second water storage tank 320 reaches the first water level lower limit. If it reaches the first water level lower limit, step B3 is triggered to execute. If it does not reach the first water level lower limit, step B4 is triggered to execute.
[0074] B3 turns on the second pumping device 340 to atomize or vaporize the remaining condensed water in the second water storage tank 320 and discharge it to the outdoor environment until it is detected that the water level in the second water storage tank 320 has not triggered the first water level lower limit within E minutes, triggering the second pumping device 340 to be turned off and triggering the execution of step B4;
[0075] B4: Determine whether the humidification function of the air-conditioning device is turned on. If so, trigger the execution of step B5;
[0076] B5: Turn on the second electric heating component and run it for F minutes, then turn it off. The purpose of electric heating and drying is to evaporate the water in the second water storage tank 320 to prevent the residual water from generating odor or breeding bacteria.
[0077] When the air conditioning equipment is heating at an ultra-low outdoor temperature (below -20°C), the heat of the refrigerant pipe 140 cannot offset the cold of the environment, causing the accumulated water in the first water tank 310 to freeze, or due to the low heat, there is no way to melt the ice in the first water tank 310 in time and there may be residual ice. According to one or more of the above embodiments of the present invention, it is possible to melt the residual ice in the first water tank 310 at an ultra-low outdoor temperature. At the same time, under the refrigeration and dehumidification conditions of the air conditioning equipment, the water in the second water tank 320 can be evaporated to avoid the growth of bacteria and the generation of odor in the water system.
