Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to a control method, device, air conditioning system and equipment. Background Technology

[0002] In existing residential and commercial air conditioning systems, oxygen generation modules are usually integrated into the air conditioning equipment as an additional functional module to realize the oxygen generation function of the air conditioner.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0022] Currently, oxygen-generating air conditioners mainly employ two technologies for oxygen production: molecular sieve pressure swing adsorption (PSA) and membrane separation. When using membrane separation, the high temperature of compressed air flowing through the membrane module reduces the permeation efficiency of oxygen in the membrane material, thus affecting oxygen production efficiency. Traditional solutions typically address this by using additional cooling devices or reducing the compressed air flow rate, but these methods increase energy consumption or negatively impact overall system efficiency. For example, using additional cooling devices increases system energy consumption, while reducing the compressed air flow rate negatively affects overall operating efficiency.

[0023] At the same time, air conditioners produce a large amount of condensate during cooling operation, and this condensate is usually discharged directly without being effectively utilized, resulting in a waste of water resources.

[0024] Based on the above, this application provides a control method, device, air conditioning system and equipment to solve the problems of reduced oxygen production efficiency of membrane modules caused by high-temperature compressed air in the prior art, and resource waste caused by the ineffective utilization of air conditioning condensate.

[0025] The air conditioning system provided in this embodiment includes an oxygen generation module and a condensate pipe. The oxygen generation module includes a membrane module, and a water-cooled jacket is provided on the outside of the membrane module. The water-cooled jacket is connected to the condensate outlet 1003 of the air conditioning system through the condensate pipe, and a condensate buffer tank is provided between the condensate pipe and the water-cooled jacket. When the air conditioning is operating in a preset target oxygen generation mode, the condensate generated during the air conditioning cooling process is introduced into the water-cooled jacket outside the membrane module. The low-temperature condensate generated during the air conditioning cooling process is used as a cooling medium to cool the membrane module, thereby reducing the temperature of the compressed air inside the membrane module and increasing the oxygen permeation rate in the membrane material. This significantly improves the oxygen generation concentration and efficiency. This not only solves the problem of low oxygen generation efficiency caused by the decrease in membrane module oxygen generation efficiency due to high-temperature compressed air in the prior art, but also realizes the effective utilization of air conditioning condensate, solving the resource waste problem caused by the ineffective utilization of air conditioning condensate in the prior art. That is, it achieves the goal of simultaneously solving the problems of low membrane module cooling efficiency and condensate waste.

[0026] The preset target oxygen production mode can refer to a pre-set oxygen production mode that utilizes the condensate generated during the air conditioning cooling process as the cooling medium for the membrane module. For example, the preset target oxygen production mode can be a cooling oxygen production mode, with the mode in which cooling and oxygen production are simultaneously activated being determined as the target oxygen production mode. This application embodiment does not impose specific limitations on this. The cooling oxygen production mode refers to the mode in which cooling and oxygen production are simultaneously activated.

[0027] In one exemplary embodiment, an air conditioning system is provided, along with a control method and control device applied to the air conditioning system, and an air conditioning device including the air conditioning system. (Reference) Figure 1 As shown, the air conditioning system 100 includes an oxygen generation module 110 and a condensate pipe 120. The oxygen generation module 110 includes a membrane assembly 1101, and a water-cooling jacket 1102 is provided on the outside of the membrane assembly 1101. If the membrane assembly 1101 is a hollow fiber membrane structure, the water-cooling jacket 1102 is wrapped around it. The water-cooling jacket 1102 is connected to the condensate outlet 1003 of the air conditioning system 100 through the condensate pipe 120. A condensate buffer tank 130 is provided between the condensate pipe 120 and the water-cooling jacket 1102. If the condensate buffer tank 130 is located between the condensate pipe 120 and the water-cooling jacket 1102, the condensate is collected through the condensate buffer tank 130 and its flow rate is adjusted to ensure stable water flow in the water-cooling jacket 1102, thereby avoiding the impact of condensate volume fluctuations on the cooling effect and improving cooling efficiency and system stability.

[0028] The air conditioning system may further include a control device 140, which is electrically connected to the control terminal of the oxygen generation module 110 and the electric flow regulating valve 121 of the condensate pipe 120. In a specific implementation, the control device 140 may use a programmable logic controller (PLC) as the core control unit. It can integrate multiple sensor interfaces, including the compressor's suction pressure sensor interface, discharge pressure sensor interface, temperature sensor interface, and humidity sensor interface, etc., enabling real-time monitoring of various operating parameters of the air conditioning system.

[0029] In this application embodiment, the control device 140 can be configured to implement the control method provided in any embodiment of this application. For example... Figure 2 As shown in the embodiments of this application, the control method may specifically include the following steps: Step 210: Determine the air conditioner's operating mode; Step 220: When the operating mode is the preset target oxygen production mode, condensate heat dissipation control is performed based on the temperature detection information of the membrane module, so as to cool the membrane module through the target condensate, which is the condensate flowing from the condensate buffer tank to the water cooling jacket.

[0030] Specifically, in this embodiment, after determining the operating mode of the air conditioner, the control device 140 can determine whether the operating mode of the air conditioner is a preset target oxygen production mode, thereby determining whether the condensate generated during the air conditioner's cooling operation can be used as the cooling medium for the membrane module 1101. Then, if the air conditioner's operating mode is the preset target oxygen production mode, the control device 140 can control the condensate heat dissipation based on the temperature detection information of the membrane module 1101, introducing the condensate generated during the air conditioner's cooling operation into the water-cooled jacket outside the membrane module 1101. This allows the condensate to act as the cooling medium for the membrane module 1101, cooling it down and reducing the temperature of the compressed air inside the membrane module 1101. This increases the oxygen permeation rate in the membrane material, significantly improving the oxygen production concentration and efficiency. This not only solves the problem of low oxygen production efficiency caused by the decrease in oxygen production efficiency of the membrane module 1101 due to high-temperature compressed air in existing air conditioning systems, but also achieves effective utilization of the air conditioner's condensate, solving the problem of resource waste caused by the ineffective utilization of air conditioner condensate in existing technologies.

[0031] To facilitate understanding of the embodiments of this application, the embodiments of this application are described by way of example below. However, it should be noted that the embodiments of this application may have the features described below, but the following description does not constitute a limitation on the protection scope of the embodiments of this application.

[0032] Optionally, in addition to the oxygen generation module 110, condensate pipe 120, condensate buffer tank 130 and control device 140, the air conditioning system provided in this application embodiment may also include other system components, such as the air conditioning outdoor unit, condenser and other key system components. This application embodiment does not limit this.

[0033] In an optional embodiment of this application, the water-cooling jacket 1102 and the membrane module 1101 can be tightly bonded together to enhance heat transfer efficiency. Specifically, the condensate flowing inside the water-cooling jacket 1102 can reduce the temperature of the compressed air inside the membrane module 1101 through heat exchange, thereby increasing the oxygen permeation rate.

[0034] For example, the water cooling jacket 1102 may include an inner spiral tube and an outer heat insulation layer. The inner spiral tube is attached to the outer surface of the membrane module 1101, and the outer heat insulation layer is used to block the heat exchange with the environment and prevent heat loss during the cooling process.

[0035] Specifically, the target condensate flowing out of the condensate buffer tank 130 flows into the water cooling jacket 1102 and flows in the spiral pipe inside the water cooling jacket 1102 to serve as the cooling water for the membrane module 1101. Through heat exchange, the membrane module 1101 is cooled and de-temperatured, thereby reducing the temperature of the compressed air inside the membrane module 1101, which in turn increases the oxygen permeation rate in the membrane material and improves the oxygen production efficiency and concentration of the membrane module.

[0036] The spiral pipeline design greatly increases the contact area and heat exchange time with the outer surface of the membrane module 1101, achieving efficient heat exchange. The heat insulation layer on the outer layer of the water cooling jacket 1102 blocks the heat exchange between the environment and the membrane module 1101, ensuring that the cooling effect comes entirely from the controllable cooling water, and avoiding interference from ambient temperature fluctuations to the system.

[0037] In addition, the water-cooled jacket 1102 is connected to the condensate outlet 1003 of the air conditioning system 100 through the condensate pipe 120, so that the low-temperature condensate generated during the cooling operation of the air conditioner first flows into the water-cooled jacket through the condensate buffer tank, and after completing the cooling of the membrane module, it is discharged outdoors.

[0038] The condensate pipe 120 serves as the condensate drainage pipe in the air conditioning system, connecting the condensate outlet 1003 of the air conditioning system 100 to the water cooling jacket 1102, providing a flow channel for the condensate, so that the condensate generated during the air conditioning cooling operation first flows into the water cooling jacket 1102 through this pipe to complete the cooling before being discharged to the outside.

[0039] For example, during air conditioning cooling operation, water vapor in the air condenses into water on the evaporator surface. The condensate flows into a condensate buffer tank, and after the flow rate is regulated by the buffer tank, it is introduced into the water-cooled jacket outside the membrane module. The condensate in the water-cooled jacket continuously cools the membrane module through heat exchange, reducing the temperature of the compressed air and thus improving the oxygen production efficiency of the membrane module.

[0040] In an optional embodiment of this application, the condensate buffer tank 130 is located between the condensate drain pipe and the water cooling jacket 1102; the inlet of the condensate buffer tank 130 may be equipped with a float level valve, which is used to dynamically maintain the water level in the buffer tank within a preset fixed capacity range to avoid overflow or flow interruption, and at the same time adjust the condensate flow rate to ensure stable water flow in the water cooling jacket.

[0041] In an optional embodiment of this application, the air conditioning system 100 may further include an intelligent temperature control module. The intelligent temperature module includes a temperature sensor that is in close contact with the surface of the membrane module 1101 and is connected to the control device 140 via a signal line. It is used to monitor the temperature of the membrane module in real time and trigger the control device 140 to adjust the condensate flow rate according to the temperature detection information of the membrane module 1101 based on the temperature change.

[0042] The control device 140 can be electrically connected to the float level valve, electric flow regulating valve, intelligent temperature control module, and membrane module 1101 of the condensate buffer tank, respectively. It can also be connected to a humidity sensor, pressure sensor, and environmental sensor to determine whether the current operating status of the air conditioner meets the preset activation conditions for the oxygen generation module based on the signals from these three sensors. Therefore, the oxygen generation module is activated only when all three sensor signals meet the preset activation conditions, ensuring stable operation of the oxygen generation module and improving the stability of the system's oxygen production.

[0043] The triple sensor signal includes three types of sensor signals: humidity sensor signal, pressure sensor signal, and environmental sensor signal. Each sensor signal is equivalent to a first sensor signal. For example, the humidity sensor signal is the first sensor signal, the pressure sensor signal is the second sensor signal, and the environmental sensor signal is the third sensor signal.

[0044] As an example of this application, in order to accurately control the flow rate of cooling water through the membrane module and maintain the temperature of the membrane module within a safe and efficient operating range, the oxygen production process of the entire air conditioning system can be divided into the following two main stages: standby preparation stage and operation control stage. The following description uses the condensate buffer tank 130 with a preset fixed capacity range of 30%-50% of the tank capacity as an example to illustrate the oxygen production process of the air conditioning system: Phase 1: Standby preparation phase (oxygen generation module not started) Specifically, after the air conditioning system is powered on, the condensate produced by the condenser flows directly into the condensate buffer tank through pipes. At this time, the float level valve installed at the inlet of the condensate buffer tank 130 starts to work to automatically maintain the water level in the condensate buffer tank 130. Specifically, the condensate buffer tank 130 serves as the outdoor water tank of the air conditioning system. When the water level in the condensate buffer tank 130 is lower than the preset minimum water level corresponding to 30% of the tank capacity, the valve controlling the condensate flow into the condensate buffer tank 130 opens, allowing water to be added to the condensate buffer tank 130. When the water level in the condensate buffer tank 130 reaches the preset maximum water level corresponding to 50% of the tank capacity, the valve controlling the condensate flow into the condensate buffer tank 130 closes to automatically maintain the water level in the condensate buffer tank, ensuring a continuous and stable water source for subsequent processes, and preventing the condensate in the condensate buffer tank from overflowing or becoming interrupted.

[0045] At this point, because at least one of the three sensor signals does not meet the preset activation conditions for the oxygen generation module, the oxygen generation module is in standby mode, waiting for the control device to send a start command. Specifically, when any one or more of the three sensor signals—humidity sensor signal, pressure sensor signal, and environmental sensor signal—do not meet the preset activation conditions for the oxygen generation module, the control device will not send a start command to the oxygen generation module, leaving the oxygen generation module in standby mode.

[0046] Phase Two: Operation and Control Phase (Oxygen Generation Module Already Started) Specifically, when the signals from the humidity sensor, pressure sensor, and environmental sensor all meet the preset activation conditions for the oxygen generation module, the control device 140 sends a start command to the oxygen generation module, causing the oxygen generation module to start, thereby initiating the oxygen generation process of the air conditioning system, and the membrane module to start working and generating heat. After the membrane module starts working, the temperature sensor on the surface of the membrane module can monitor the temperature rise caused by oxygen production in real time, obtaining temperature detection information. This information allows the control device to control condensate cooling. For example, based on the temperature data, the membrane module temperature is compared with a preset safe temperature threshold. If the membrane module temperature is too high (above the preset safe temperature threshold), the control device, through the intelligent temperature control module, will issue a first adjustment command to increase the opening of the electric flow regulating valve. This increases the valve's opening, allowing more condensate from the condensate buffer tank to flow through the water-cooling jacket, achieving dynamic cooling control. If the membrane module temperature is too low, the control device, through the intelligent temperature control module, will issue a second adjustment command to decrease the opening of the electric flow regulating valve. This reduces the cooling water flow, saving energy and preventing the membrane module from overcooling.

[0047] After the target condensate enters the water cooling jacket 1102, it flows in the spiral tube inside the water cooling jacket 1102 and absorbs the heat of the membrane module 1101 through heat exchange, so that the target condensate becomes warm water that has absorbed heat and flows out from the water cooling jacket 1102.

[0048] In an optional embodiment of this application, the control device 140 may internally store a dedicated control algorithm program. When the air conditioner is turned on, it determines whether the air conditioner's operating mode is a preset target oxygen production mode. If the air conditioner's operating mode is the preset target oxygen production mode, the originally discharged condensate water is converted into cooling resources for the membrane module 1101. That is, condensate water heat dissipation control is performed based on the temperature detection information of the membrane module 1101 to achieve cooling of the outdoor air, thereby improving oxygen production efficiency. Optionally, determining the air conditioner's operating mode in this embodiment may specifically include the following sub-steps: Sub-step 2101: When the air conditioner is on, determine whether the condensate water is available and detect whether the oxygen generation module is on. Sub-step 2102: When the condensate is available and the oxygen generation module is turned on, the target oxygen generation mode is determined as the operating mode.

[0049] Specifically, in order to utilize the low-temperature condensate generated during the cooling operation of the air conditioner as the cooling medium for the membrane module 1101, this embodiment of the application can determine whether the condensate is available after the air conditioner is turned on by the control device 140. If the condensate is available, the operation priority of the oxygen generation module 110 can be automatically started or increased. For example, when the oxygen generation module 110 is turned on and the air conditioner is in cooling operation, the preset target oxygen generation mode can be determined as the current operation mode of the air conditioner so that the condensate heat dissipation control can be performed according to the target oxygen generation mode.

[0050] The activation of the oxygen generation module 110 indicates that the air conditioner has activated the oxygen generation mode. Therefore, in an optional embodiment of this application, the mode in which cooling and oxygen generation are activated simultaneously can be defined as the target oxygen generation mode. When the air conditioner is in the operation mode of cooling and oxygen generation being activated simultaneously, the air conditioner is considered to be in the target oxygen generation mode. When the air conditioner is not in the operation mode of cooling and oxygen generation being activated simultaneously, the air conditioner is considered not to be in the target oxygen generation mode.

[0051] Optionally, considering that the condensate in the air conditioner is mainly generated by the air conditioning cooling process, this embodiment of the application can determine whether the condensate is available by judging whether the air conditioner is in cooling mode after it is turned on. Specifically, this embodiment of the application can determine whether the condensate is available when the air conditioner is turned on by: judging whether the air conditioner is in cooling mode; when the air conditioner is in cooling mode, detecting whether the condensate flow rate of the condensate buffer tank 120 reaches a preset available flow rate; and determining that the condensate is available when the condensate flow rate reaches the available flow rate.

[0052] The condensate flow rate of the condensate buffer tank 120 refers to the flow rate of condensate from the condensate buffer tank 120 to the water-cooled jacket. The higher the flow rate, the more significant the cooling effect of the condensate on the membrane module 1101. The preset available flow rate refers to the minimum flow rate set in advance for the cooling requirements of the membrane module 1101. When the condensate flow rate reaches this available flow rate, it is considered that the condensate can be used to cool the membrane module 1101 to meet the corresponding cooling requirements. When the condensate flow rate does not reach the available flow rate, the condensate is considered unusable, i.e., the condensate is in an unusable state. For example, when the condensate flow rate does not reach the available flow rate, even if all the water tank valves of the condensate buffer tank 120 are opened to use the condensate flowing out of the condensate buffer tank 120 to cool the membrane module 1101, the corresponding cooling requirements of the membrane module 1101 cannot be met.

[0053] As can be seen, in this embodiment of the application, after the air conditioner is turned on, the control device 140 can determine whether the air conditioner is in cooling mode, and thus determine whether the air conditioner is in cooling state. If the air conditioner is in cooling mode, it can be determined that the air conditioner is in cooling state at this time. Subsequently, the availability of condensate buffer tank 120 can be determined by detecting whether the condensate flow rate reaches the preset available flow rate. When the condensate flow rate of condensate buffer tank 120 is the preset available flow rate, it is confirmed that the condensate is available, so that the condensate heat dissipation control can be performed according to the temperature detection information of membrane module 1101, so as to use the condensate to cool membrane module 1101, thereby reducing the temperature of membrane module 1101 until the temperature of the compressed air inside membrane module 1101 drops to within the preset oxygen production temperature range.

[0054] The preset oxygen production temperature range can be set according to the oxygen production requirements of the oxygen production module 110. For example, based on the material and structure of the membrane module 1101, the temperature at which the membrane module 1101 can achieve the maximum oxygen production efficiency can be determined as the oxygen production reference temperature. The temperature error can be determined according to the control accuracy, so that the difference between the oxygen production reference temperature and the temperature error is determined as the minimum value of the oxygen production temperature range, and the sum of the oxygen production reference temperature and the temperature error is determined as the maximum value of the oxygen production temperature range. Thus, the preset oxygen production temperature range corresponding to the membrane module 1101 can be determined according to the oxygen production reference temperature and the temperature error. This application embodiment does not impose specific limitations on the oxygen production temperature range.

[0055] In one optional embodiment of this application, to avoid the impact of fluctuations in condensate flow on the cooling effect, a float level valve can be installed in the condensate buffer tank 120. For example, a float level valve can be installed at the inlet of the condensate buffer tank 120 to automatically adjust the condensate flow rate into the condensate buffer tank 120. This allows the water level in the condensate buffer tank 120 to be dynamically maintained within a preset fixed capacity range based on the condensate flow rate, thereby preventing overflow or flow interruption and ensuring a stable supply of target condensate.

[0056] The preset fixed capacity range can be determined based on the maximum capacity of the condensate buffer tank 120 and the target condensate supply demand. For example, the target condensate supply demand can be determined based on the cooling requirements of the membrane module 1101. Based on the target condensate supply demand and the maximum capacity of the condensate buffer tank 120, 30% of the maximum capacity of the condensate buffer tank 120 can be determined as the minimum capacity threshold of the fixed capacity range, and 50% of the maximum capacity of the condensate buffer tank 120 can be determined as the maximum capacity threshold of the fixed capacity range. Based on this fixed capacity range, the flow rate of condensate into the condensate buffer tank 120 can be automatically adjusted by the float level valve so that the water level in the condensate buffer tank 120 is dynamically maintained within the fixed capacity range of 30%-50% of the capacity of the condensate buffer tank 120.

[0057] Specifically, when the water level in the condensate buffer tank 120 is lower than 30% of its capacity, the float level valve at the inlet of the condensate buffer tank 120 is opened, allowing condensate to flow into the condensate buffer tank 120 through the open float level valve. This enables condensate collection within the condensate buffer tank 120, preventing the cold water flow from the condensate buffer tank 120 from being interrupted. Conversely, when the water level in the condensate buffer tank 120 reaches 50% of its capacity, the float level valve is closed, preventing condensate from continuing to flow into the condensate buffer tank 120 and thus avoiding overflow.

[0058] Furthermore, when the water level in the condensate buffer tank 120 is between 30% and 50% of its capacity, the condensate flow rate in the condensate buffer tank 120 can be adjusted by regulating the opening of the float level valve and / or by adjusting various electric flow regulating valves installed on the condensate pipeline 120. This controls the flow rate of the target condensate, thereby controlling the cooling effect of the target condensate on the membrane module 1101.

[0059] The electric flow regulating valve may include a water tank valve for the condensate buffer tank 120, so as to control the flow rate of condensate flowing into the condensate buffer tank 120 through the water tank valve. This application embodiment does not limit this.

[0060] In an exemplary embodiment of this application, the condensate buffer tank 120 may be equipped with a water tank valve to control the flow rate of condensate into the condensate buffer tank 120, so as to dynamically maintain the condensate water level in the condensate buffer tank 120 and avoid the impact of condensate flow fluctuation on the cooling effect.

[0061] In specific implementations, the water tank valves provided for the condensate buffer tank 120 may include, but are not limited to, the inlet valve and outlet valve of the condensate buffer tank 120, etc., and this application embodiment does not limit this.

[0062] The inlet valve of the condensate buffer tank 120 can be used to control the flow rate of condensate into the condensate buffer tank 120, thereby controlling the condensate flow rate. For example, the inlet valve of the condensate buffer tank 120 can be an electric valve installed at the inlet of the condensate buffer tank 120 to control the flow rate of condensate into the condensate buffer tank 120. Specifically, the larger the opening degree of the inlet valve, the greater the flow rate of condensate into the condensate buffer tank 120 within a preset unit time; that is, the larger the opening degree of the inlet valve, the greater the condensate flow velocity into the condensate buffer tank 120. If the opening degree of the inlet valve is zero, that is, when the inlet valve is completely closed, the condensate flow rate into the condensate buffer tank 120 within a preset unit time can be considered zero, that is, the condensate flow velocity into the condensate buffer tank 120 is zero. The condensate flow velocity of the condensate buffer tank 120 refers to the velocity at which condensate flows into the condensate buffer tank 120.

[0063] The outlet valve of the condensate buffer tank 120 can be used to control the flow rate of condensate flowing out of the condensate buffer tank 120, thereby controlling the condensate flow rate. For example, the outlet valve of the condensate buffer tank 120 can be an electric valve installed at the outlet of the condensate buffer tank 120 to control the flow rate of condensate flowing out of the condensate buffer tank 120. Specifically, the larger the opening degree of the outlet valve, the greater the flow rate of condensate flowing out of the condensate buffer tank 120 within a preset unit time; that is, the larger the opening degree of the outlet valve, the greater the condensate flow velocity of the condensate buffer tank 120. If the opening degree of the outlet valve is zero, that is, when the outlet valve is completely closed, it can be considered that the condensate flow rate of the condensate buffer tank 120 within a preset unit time is zero, that is, the condensate flow velocity of the condensate buffer tank 120 is zero. Here, the condensate flow velocity of the condensate buffer tank 120 refers to the flow rate of condensate flowing out of the condensate buffer tank 120.

[0064] In specific implementations, in addition to setting 30% of the capacity of the condensate buffer tank 120 as the minimum capacity threshold of the fixed capacity range, other capacity values ​​can also be set as the minimum capacity threshold of the fixed capacity range. For example, the minimum capacity threshold of the fixed capacity range can be set as 25% or 35% of the capacity of the condensate buffer tank 120. The specific value can be determined according to the flow rate of condensate flowing into and out of the condensate buffer tank 120. This application embodiment does not limit this.

[0065] For example, to address the problem of poor cooling performance of the membrane module 1101 due to interruption of the target condensate flow out of the condensate buffer tank 120, when the flow rate of condensate slowly flowing into the condensate buffer tank 120 is greater than the flow rate of condensate slowly flowing out of the condensate buffer tank 120 (i.e., when the condensate inflow velocity of the condensate buffer tank 120 is greater than the condensate outflow velocity), the minimum capacity threshold of the fixed capacity range can be set to a relatively small capacity threshold. For instance, the minimum capacity threshold of the fixed capacity range can be set to 10% of the capacity of the condensate buffer tank 120, or... Other values ​​smaller than 10%; when the flow rate of condensate slowly flowing into the condensate buffer tank 120 is less than the flow rate of condensate slowly flowing out of the condensate buffer tank 120, that is, when the condensate inflow rate of the condensate buffer tank 120 is less than the condensate outflow rate of the condensate buffer tank 120, the minimum capacity threshold of the fixed capacity range can be set to a relatively large capacity threshold. For example, the minimum capacity threshold of the fixed capacity range can be set to 35% of the capacity of the condensate buffer tank 120 or other values ​​that are larger than 30% and smaller than the maximum capacity threshold of the fixed capacity range. This application example does not limit this.

[0066] In addition, the maximum capacity threshold for the fixed capacity range can be set to 50% of the capacity of the condensate buffer tank 120, or other values, such as 45% or 55% of the capacity of the condensate buffer tank 120. The specific value can be determined based on the flow rate of condensate flowing into and out of the condensate buffer tank 120, and this application embodiment does not limit this.

[0067] For example, to avoid overflow of the condensate buffer tank 120, when the flow rate of condensate slowly flowing into the condensate buffer tank 120 is greater than the flow rate of condensate slowly flowing out of the condensate buffer tank 120, that is, when the condensate inflow velocity of the condensate buffer tank 120 is greater than the condensate outflow velocity of the condensate buffer tank 120, the maximum capacity threshold of the fixed capacity range can be set to a relatively small capacity threshold. For example, the maximum capacity threshold of the fixed capacity range can be set to 45% of the capacity of the condensate buffer tank 120, or set to be less than 50% of the capacity of the condensate buffer tank 120 and less than... Other values ​​beyond the minimum capacity threshold for a fixed capacity range are not limited in this application example. When the flow rate of condensate slowly flowing into the condensate buffer tank 120 is less than the flow rate of condensate slowly flowing out of the condensate buffer tank 120, that is, when the condensate inflow rate of the condensate buffer tank 120 is less than the condensate outflow rate of the condensate buffer tank 120, the minimum capacity threshold for the fixed capacity range can be set to a relatively large capacity threshold, such as 55% of the capacity of the condensate buffer tank 120 or a value greater than 55%, etc. This application example does not limit this.

[0068] In an optional embodiment of this application, after determining that the air conditioner's operating mode is the preset target oxygen production mode, the condensate cooling mode can be activated by the control device 140. Based on this condensate cooling mode, the temperature detection information of the membrane module 1101 can be obtained. The condensate flow rate of the condensate buffer tank 120 can be adjusted according to the temperature detection information, thereby controlling the flow rate of the target condensate flowing into the water cooling jacket. In turn, by controlling the flow rate of the target condensate, the cooling effect of the target condensate on the membrane module 1101 can be controlled, so that the temperature of the membrane module 1101 can be reduced to within the preset oxygen production temperature range.

[0069] Optionally, in the embodiments of this application, when the operating mode is the preset target oxygen generation mode, the condensate heat dissipation control is performed based on the temperature detection information of the membrane module 1101. Specifically, this may include: when the air conditioner's operating mode is the preset target oxygen generation mode, activating the preset condensate heat dissipation mode corresponding to the oxygen generation module 110; and adjusting the condensate flow rate of the condensate buffer tank 120 based on the condensate heat dissipation mode and the temperature detection information of the membrane module 1101 to control the flow rate of the target condensate.

[0070] The preset condensate cooling mode corresponding to the oxygen generation module 110 can refer to a condensate cooling mode pre-set for the oxygen generation module 110. Specifically, in this embodiment, after determining that the current operating mode of the air conditioner is the preset target oxygen generation mode, the control device 140 can control the air conditioning system to start the preset condensate cooling mode corresponding to the oxygen generation module 110. Based on this condensate cooling mode, the temperature detection information of the membrane module 1101 can be obtained, and the condensate flow rate of the condensate buffer tank 120 can be adjusted in real time according to the currently obtained temperature detection information to control the cooling effect of the condensate on the membrane module 1101, thereby achieving the purpose of real-time control of the membrane module temperature.

[0071] In an optional embodiment of this application, the temperature of the membrane module 1101 can be detected by a temperature sensor, and the temperature information detected by the temperature sensor can be used as the temperature detection information of the membrane module 1101. The membrane module temperature can then be determined based on this temperature detection information. The membrane module temperature characterizes the current actual temperature of the membrane module 1101.

[0072] Optionally, in order to better control the oxygen production temperature of the oxygen module 110, in the process of controlling condensate heat dissipation based on the temperature detection information of the membrane module 1101, in addition to determining the membrane module temperature based on the temperature detection information of the membrane module 1101, the preset oxygen production temperature information can also be obtained to determine the preset oxygen production temperature corresponding to the membrane module 1101. The condensate heat dissipation control is then performed based on the temperature difference between the membrane module temperature and the oxygen production temperature, so that the membrane module 1101 can produce oxygen within the preset oxygen production temperature range, thereby maximizing the oxygen production efficiency of the membrane module 1101.

[0073] In one optional embodiment of this application, one or more electric flow regulating valves can be installed on the condensate pipe 120 of the air conditioning system to regulate the condensate flow rate of the condensate buffer tank 120, thereby controlling the cooling effect of the condensate on the membrane module 1101.

[0074] Optionally, the condensate pipe 120 in this embodiment is further equipped with an electric flow regulating valve. The step of adjusting the condensate flow rate of the condensate buffer tank 120 based on the temperature detection information of the membrane module 1101 may specifically include: acquiring the temperature detection information and oxygen generation temperature information of the membrane module 1101; determining the membrane module temperature based on the temperature detection information, and determining a preset oxygen generation temperature corresponding to the membrane module 1101 based on the oxygen generation temperature information; and adjusting the opening of the electric flow regulating valve based on the temperature difference between the membrane module temperature and the oxygen generation temperature to regulate the condensate flow rate. The preset oxygen generation temperature corresponding to the membrane module 1101 refers to the oxygen generation temperature pre-set for the membrane module 1101, and this oxygen generation temperature corresponds to the point where the membrane module 1101 can achieve maximum oxygen generation efficiency.

[0075] In an optional embodiment of this application, in order to quickly control the temperature of the membrane module 1101 within a preset oxygen production temperature range and ensure the oxygen production effect of the membrane module 1101, when the temperature difference between the membrane module temperature and the oxygen production temperature is detected to exceed the preset temperature difference range, this embodiment of the application can determine whether it is necessary to increase the opening of the electric flow regulating valve by judging whether the membrane module temperature is greater than the oxygen production temperature, so as to achieve the purpose of rapid cooling by increasing the condensate flow rate, so that the temperature of the membrane module 1101 can be quickly reduced to within the preset oxygen production temperature range.

[0076] Optionally, in this embodiment of the application, the opening of the electric flow regulating valve is adjusted according to the temperature difference between the membrane module temperature and the oxygen production temperature. Specifically, this may include: if the temperature difference exceeds a preset temperature difference range, determining whether the membrane module temperature is greater than the oxygen production temperature; if the membrane module temperature is greater than the oxygen production temperature, increasing the opening of the electric flow regulating valve to increase the flow rate of condensate from the condensate buffer tank 120 per unit time. That is, when the membrane module temperature is greater than the oxygen production temperature and the temperature difference between the two exceeds a preset temperature difference range, the flow rate of the target condensate is increased by controlling the opening of the electric flow regulating valve to enhance the cooling effect of the target condensate, thereby enabling the temperature of the membrane module 1101 to quickly drop to within the preset oxygen production temperature range. If the membrane module temperature is not greater than the oxygen production temperature, the opening of the electric flow regulating valve is reduced. This reduces the flow rate of condensate from the condensate buffer tank 120 per unit time. Specifically, when the membrane module temperature is lower than the oxygen production temperature and the temperature difference between them exceeds a preset temperature difference range, the opening of the electric flow regulating valve is reduced to slow down the flow rate of the target condensate, thereby reducing the flow rate of condensate from the condensate buffer tank 120 per unit time. This prevents the target condensate from overcooling the membrane module 1101, which could lead to an excessively low temperature for the membrane module 1101.

[0077] Of course, when the temperature difference between the membrane module temperature and the oxygen production temperature exceeds the preset temperature difference range, in addition to determining the adjustment mode of the electric flow regulating valve by judging whether the membrane module temperature is greater than the oxygen production temperature, other methods can also be used to determine the adjustment mode of the electric flow regulating valve. For example, the adjustment mode of the electric flow regulating valve can be determined by judging whether the membrane module temperature is less than the oxygen production temperature. This application embodiment does not impose specific limitations on this.

[0078] In another optional embodiment of this application, in order to quickly control the temperature of the membrane module 1101 within the preset oxygen production temperature range, when the temperature difference between the membrane module temperature and the oxygen production temperature is detected to exceed the preset temperature difference range, this embodiment of the application can determine whether the opening of the electric flow regulating valve needs to be reduced by judging whether the membrane module temperature is lower than the oxygen production temperature. This is done by reducing the condensate flow rate to avoid the target condensate from overcooling the membrane module 1101, thereby solving the problem of the membrane module temperature being too low and affecting the oxygen production efficiency due to the target condensate overcooling the membrane module 1101.

[0079] Optionally, in this embodiment of the application, the opening of the electric flow regulating valve is adjusted according to the temperature difference between the membrane module temperature and the oxygen production temperature. Specifically, this may include: if the temperature difference exceeds a preset temperature difference range, determining whether the membrane module temperature is lower than the oxygen production temperature; if the membrane module temperature is lower than the oxygen production temperature, then reducing the opening of the electric flow regulating valve. That is, when the membrane module temperature is lower than the oxygen production temperature and the temperature difference between the two exceeds a preset temperature difference range, the opening of the electric flow regulating valve is reduced to decrease the flow rate of condensate flowing out of the condensate buffer tank 120 per unit time, thereby solving the problem of the membrane module 1101 being too cold due to excessive cooling of the membrane module 1101 by the target condensate. If the membrane module temperature is not lower than the oxygen production temperature, the opening of the electric flow regulating valve is increased. That is, when the membrane module temperature is greater than the oxygen production temperature and the temperature difference between the two exceeds the preset temperature difference range, the opening of the electric flow regulating valve is increased to increase the flow rate of condensate water flowing out of the condensate buffer tank 120 per unit time, thereby enhancing the cooling effect of the target condensate water and enabling the temperature of the membrane module 1101 to be quickly reduced to within the preset oxygen production temperature range.

[0080] Optionally, after determining the operating mode of the air conditioner, the control method provided in this application embodiment may further include the following steps: determining whether the operating mode is a preset target oxygen production mode; if the operating mode is not the target oxygen production mode, controlling the water tank valve to open, so as to adjust the condensate flow rate of the condensate buffer tank to the preset water tank flow rate corresponding to the condensate buffer tank. Wherein, the preset water tank flow rate corresponding to the condensate buffer tank refers to the maximum flow rate preset for the condensate buffer tank.

[0081] For example, such as Figure 3As shown, after the air conditioner is turned on, the control device in the air conditioning system can determine the air conditioner's operating mode and whether it is the target oxygen production mode where cooling and oxygen production are simultaneously activated. If the air conditioner's operating mode is the target oxygen production mode where cooling and oxygen production are simultaneously activated, then the condensate cooling mode is activated. That is, when the air conditioner's operating mode is cooling and oxygen production mode, the condensate cooling mode is activated. Subsequently, based on this condensate cooling mode, condensate cooling control can be performed, that is, condensate is collected through a condensate buffer tank and the condensate flow rate is adjusted to ensure stable water flow in the water-cooled jacket, improving cooling efficiency and system stability. If the air conditioner's operating mode is... If the target oxygen generation mode is not simultaneously activated for both cooling and oxygen generation, then the condensate cooling mode will not be activated. In other words, if the air conditioner is not operating in both cooling and oxygen generation modes simultaneously, the condensate cooling mode will not be activated. In this case, the outdoor condensate tank valve can be fully opened, that is, the opening degree of the condensate buffer tank valve can be adjusted to the maximum opening threshold of the tank valve, so that the condensate tank flow rate can be adjusted to the maximum flow rate threshold. This allows the condensate buffer tank and the water-cooled jacket to act as drain pipes in the air conditioning system, allowing the condensate to be discharged directly through the condensate pipes, thereby enabling the air conditioner to operate normally. In other words, the control device controls the air conditioning system to operate in the normal operating mode.

[0082] Specifically, after activating the condensate cooling mode, the control device can control the condensate cooling based on this mode. Specifically, it controls the opening of the electric flow regulating valve corresponding to the condensate buffer tank to collect condensate and regulate its flow rate. This allows for condensate collection and diversion via the buffer tank. Furthermore, the temperature of the oxygen generation module can be collected using temperature detection methods, such as temperature sensors on the membrane module. This temperature information can be used to determine the membrane module temperature. Based on the detected membrane module temperature, the opening of the electric flow regulating valve can be adjusted to regulate the condensate flow rate. In other words, adjusting the condensate flow rate according to the membrane module temperature allows the target condensate to cool the membrane module, lowering its temperature and thus increasing the oxygen permeation rate.

[0083] As can be seen, the embodiments of this application utilize the low-temperature characteristics of air conditioning condensate to directly reduce the temperature of compressed air inside the membrane module through heat exchange, effectively increasing the oxygen permeation rate in the membrane material, thereby improving the oxygen production concentration and efficiency. This solves the efficiency bottleneck caused by high temperature in traditional membrane separation oxygen production technology, and converts the condensate that was originally directly discharged into a cooling resource, avoiding water waste and improving the resource utilization rate of the air conditioning system.

[0084] like Figure 4As shown, this application embodiment also provides an air conditioning device 400, which includes the air conditioning system 100 provided in any of the above embodiments of this application. After the air conditioner is started, the air conditioning device 400 can execute the steps of the control method provided in any embodiment of this application through the control device 140 in the air conditioning system 100. When the air conditioner is in the target oxygen production mode, the condensate heat dissipation control is performed based on the temperature detection information of the membrane module to introduce the condensate generated during the air conditioner's cooling operation into the water-cooled jacket outside the membrane module. Thus, the low-temperature condensate generated during the air conditioner's cooling operation can be used as the cooling medium for the membrane module to cool it, thereby reducing the temperature of the compressed air inside the membrane module and increasing the oxygen permeation rate in the membrane material. This not only solves the problem of low oxygen production efficiency caused by the decrease in oxygen production efficiency of the membrane module due to high-temperature compressed air in the prior art, but also realizes the effective utilization of air conditioning condensate, solving the problem of resource waste caused by the ineffective utilization of air conditioning condensate in the prior art.

[0085] As can be seen, the embodiments of this application combine the cooling requirements of air conditioning condensate with those of membrane modules. Through the coordinated design of buffer tank flow stabilization and intelligent temperature control, it not only solves the high-temperature efficiency bottleneck of traditional membrane separation oxygen production, but also realizes the resource utilization of condensate. Moreover, it requires no additional energy consumption, and the system structure is simple and highly compatible. It can be widely used in the integration of oxygen production functions in household and commercial air conditioners, and is especially suitable for scenarios with high requirements for oxygen production efficiency and energy saving.
