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.
[0038] The air conditioning refrigerant leakage detection and treatment method and apparatus of this application are described below with reference to Figures 1-4, and their embodiments are described in detail.
[0039] The following is a detailed description of an embodiment of the air conditioning system described in this application. Figure 1 shows a schematic diagram of the air conditioning system provided in this application embodiment. The specific implementation process includes the following parts: an indoor unit 102, a linked fan 103, and a refrigerant detector 101. Both the indoor unit 102 and the linked fan 103 are communicatively connected to the refrigerant detector 101. The refrigerant detector 101 is externally mounted and detects refrigerant leakage. Based on the detection result, it switches the communication state with the indoor unit 102 and / or the linked fan 103. Additionally, the air conditioning system may also include: an alarm device electrically connected to the refrigerant detector 101. When the refrigerant detector 101 detects that the refrigerant concentration exceeds a refrigerant concentration threshold, the alarm device performs a periodic alarm action; and / or a reset button electrically connected to the alarm device. When the reset button is triggered, the reset button controls the alarm device to stop alarming within a first time period T1.
[0040] The following is a detailed description of an embodiment of the air conditioning refrigerant leakage detection and processing method described in this application. As shown in Figure 2, it is one of the flowcharts of the air conditioning refrigerant leakage detection and processing method provided in this application. The specific implementation process includes the following steps:
[0041] Step 201: Detect the refrigerant concentration in the air-conditioned operating space and obtain the current refrigerant concentration data.
[0042] In this embodiment, a refrigerant detector can be used to detect the refrigerant concentration within the air-conditioned operating space and obtain the current refrigerant concentration data. The refrigerant detector is located outside the air conditioner and has an independent power supply. Internally, it includes a processor module, a storage module, and a refrigerant concentration detection sensor. Because the refrigerant detector is set up independently of the air conditioner, its placement is more flexible. The refrigerant can be R32, R22, or other refrigerants used in air conditioners, and is not specifically limited here.
[0043] Step 202: If the refrigerant concentration data exceeds the refrigerant concentration threshold, control the disconnection of the transmission signal between the refrigerant detector and the indoor unit of the air conditioner and / or the linked fan, so as to control the operation of the fan in the indoor unit of the air conditioner or the linked fan by disconnecting the transmission signal, so as to adjust the refrigerant concentration in the air-conditioned operating space to the target concentration value.
[0044] In this embodiment, after acquiring the current refrigerant concentration data, if the refrigerant concentration data exceeds the refrigerant concentration threshold, the refrigerant detector can control the disconnection of the transmission signal connections between the refrigerant detector and the indoor unit of the air conditioner and the linked fan. For example, it can control the short-circuit of the transmission signal connections between the refrigerant detector and the indoor unit of the air conditioner and the linked fan, thereby triggering the indoor unit of the air conditioner to generate a corresponding fault code and send it to the user terminal associated with the indoor unit. It can also control the fan in the indoor unit to operate, sending air into the air-conditioned operating space to disturb the leaked refrigerant. Furthermore, it can trigger the linked fan to operate, exhausting air outdoors to adjust the refrigerant concentration in the air-conditioned operating space to the target concentration value. The refrigerant detector is connected to both the indoor unit of the air conditioner and the linked fan. This application uses the operation of the fan in the indoor unit to send air into the air-conditioned operating space, creating airflow disturbance, while simultaneously controlling the operation of the linked fan (independent of the air conditioner's exterior) to exhaust air, thereby promptly discharging the leaked refrigerant outdoors. This achieves a better and faster reduction in the leaked refrigerant concentration, thus ensuring user safety.
[0045] In addition, in this embodiment, after acquiring the current refrigerant concentration data, if the refrigerant concentration data exceeds the refrigerant concentration threshold, the buzzer installed in the refrigerant detector can be controlled to emit a periodic beep, and the alarm light installed in the refrigerant detector can be controlled to flash periodically. Furthermore, after controlling the disconnection of the transmission signals between the refrigerant detector and the indoor unit of the air conditioner and the linked fan, the audible and visual alarm in the indoor unit of the air conditioner can be triggered to issue an alarm message, thereby more effectively and promptly reminding the user of the refrigerant leak.
[0046] To improve the user experience and avoid interference from continuous beeping and flashing alarm lights, this application, after controlling the buzzer inside the refrigerant detector to emit periodic beeps and the alarm light inside the refrigerant detector to flash periodically, can also obtain user operation information for triggering a reset button. In response to this user-triggered reset button operation information, the buzzer and alarm light inside the refrigerant detector are controlled to stop operating within a target time period (e.g., 2 minutes). To ensure safety, the refrigerant concentration in the air-conditioned operating space continues to be detected within the target time period to further obtain real-time refrigerant concentration data. If the real-time refrigerant concentration data still exceeds the refrigerant concentration threshold, the buzzer inside the refrigerant detector needs to be triggered again to emit periodic beeps and the alarm light inside the refrigerant detector to flash periodically, reminding the user to take immediate action.
[0047] In addition, after controlling the buzzer installed in the refrigerant detector to emit periodic beeps and the alarm light installed in the refrigerant detector to flash periodically, this application can continue to detect the refrigerant concentration in the air-conditioning operating space. If the refrigerant concentration data in the air-conditioning operating space reaches the target concentration value, it is determined that the refrigerant leakage problem has been resolved. Then, the buzzer and alarm light installed in the refrigerant detector are controlled to stop operating within the target time period, and the transmission signal connection between the refrigerant detector and the indoor unit of the air conditioner and the linked fan is restored, thereby enabling continued monitoring of refrigerant leakage problems during subsequent air-conditioning use and improving detection accuracy.
[0048] In other words, if the refrigerant detector detects an excessive refrigerant concentration in the air, its buzzer will sound periodically and the corresponding alarm light will flash periodically. At this time, the refrigerant detector will send a command to cut off the signal with the indoor unit / valve box and the linked fan. The indoor unit will simultaneously issue an audible and visual alarm, flash the corresponding fault code, and run at high fan speed. If the user connects the linked fan, the fan will also run at high fan speed. If the user finds the refrigerant detector too noisy, they can press the reset button on the refrigerant detector. The buzzer and the corresponding fault light will turn off for two minutes, during which time the refrigerant detector will continue to operate normally, maintaining the disconnection of the signal with the indoor unit / valve box and the linked fan. If the concentration is still abnormal after two minutes, the audible and visual alarm will resume. The audible and visual alarm will disappear only when the refrigerant detector detects that the refrigerant concentration has dropped below the set value, and the signal between the refrigerant detector and the indoor unit / valve box and the linked fan will be restored.
[0049] In this embodiment, communication data collected by the communication sensor within the refrigerant detector is acquired. This communication data is compared and analyzed with preset standard communication data to obtain a communication fault detection result for the refrigerant detector. And / or, a self-test program within the refrigerant detector is triggered to obtain operating data. This operating data is compared and analyzed with preset standard operating data to obtain a self-test anomaly detection result for the refrigerant detector. And / or, the actual usage time of the refrigerant detector is recorded by a timer within the refrigerant detector. This actual usage time is compared and analyzed with a preset standard usage time to obtain a lifespan detection result for the refrigerant detector. Based on the communication fault detection result, the self-test anomaly detection result, and the lifespan detection result, a buzzer installed within the refrigerant detector is triggered to emit a corresponding mode of beeping, and an alarm light installed within the refrigerant detector is controlled to flash in a corresponding mode. This facilitates the user's determination of the refrigerant detector's operating status.
[0050] The process of triggering the buzzer in the refrigerant detector to emit a corresponding mode of beeping and the alarm light in the refrigerant detector to flash in a corresponding mode based on the communication fault detection result, the self-test anomaly detection result, and the service life detection result includes: triggering the buzzer in the refrigerant detector to emit a first mode of beeping and the alarm light (i.e., LED light) in the refrigerant detector to flash in a first mode, where the control parameters in the first mode are the parameters corresponding to number 2 in the following table; triggering the buzzer in the refrigerant detector to emit a second mode of beeping and the alarm light in the refrigerant detector to flash in a second mode, where the control parameters in the second mode are the parameters corresponding to number 3 in the following table; and triggering the buzzer in the refrigerant detector to emit a third mode of beeping and the alarm light in the refrigerant detector to flash in a third mode, where the control parameters in the third mode are the parameters corresponding to number 4 in the following table. This allows users to quickly identify different fault states of the refrigerant detector by observing the difference between flashing and beeping sounds.
[0051] For example, the refrigerant detector monitors the refrigerant concentration in the air in real time. If the detector experiences a communication failure, self-test anomaly, or reaches the end of its lifespan, its buzzer will sound periodically and the corresponding alarm light will flash periodically. At this time, the signals to the indoor unit / valve box and the linked fan are normal. If the user finds the refrigerant detector too noisy, they can press the reset button on the detector. The buzzer and corresponding alarm light will turn off for two minutes, during which time the detector will operate normally. If an abnormality is still detected after two minutes, the audible and visual alarms will resume.
[0052] This application solves the problem of alerting people in an enclosed space to refrigerant leaks by using audible and visual alarms and controlling the unit's operating status, thereby reducing the refrigerant concentration in the environment. As shown in Figure 3, firstly, a refrigerant detector monitors the refrigerant concentration in the air in real time. Secondly, if the refrigerant detector detects that the refrigerant concentration in the air exceeds the standard or that it is abnormal, it will sound an alarm through its indicator light and buzzer at a fixed frequency and decibel. If the refrigerant leak reaches a critical point, it will disconnect the signal from the indoor unit / valve box and the linked fan, closing the valve and running the fan in the indoor unit at high speed to reduce the refrigerant concentration in the air and reduce the risk of explosion. In contrast, existing built-in detectors can only be installed in the indoor unit or valve box and can only be linked with the indoor unit, resulting in a limited installation location. They cannot be linked with exhaust fans, rely on the indoor unit, and cannot achieve their own monitoring and alarm functions. Furthermore, they are not suitable for refrigerant detection in multi-tenant scenarios. When the built-in detector fails to detect a refrigerant leak, the refrigerant detector can perform real-time monitoring and alarm for the leak by utilizing its independent power supply and flexible installation location.
[0053] The air conditioning refrigerant leakage detection and handling method provided in this application detects the refrigerant concentration in the air conditioning operating space to obtain the current refrigerant concentration data. When the refrigerant concentration data exceeds the refrigerant concentration threshold, the transmission signal connection between the refrigerant detector and the indoor unit and / or the linked fan is cut off. This cut-off of the transmission signal controls the operation of the fan in the indoor unit or the linked fan to adjust the refrigerant concentration in the air conditioning operating space to the target concentration value. This method effectively improves the flexibility and accuracy of air conditioning refrigerant leakage detection, and can quickly reduce the concentration of leaked refrigerant, thereby ensuring user safety.
[0054] The air conditioning refrigerant leak detection and processing device provided in this application is described below. The air conditioning refrigerant leak detection and processing device described below can be referred to in conjunction with the air conditioning refrigerant leak detection and processing method described above. The air conditioning refrigerant leak detection and processing device described in this application specifically includes the following parts:
[0055] The air conditioning refrigerant leakage detection unit is used to detect the refrigerant concentration in the air-conditioned operating space and obtain the current refrigerant concentration data.
[0056] An air conditioning refrigerant leakage handling unit is used to, when the refrigerant concentration data exceeds a refrigerant concentration threshold, control the disconnection of the transmission signal connection between the refrigerant detector and the indoor unit of the air conditioner and the linked fan, respectively. This disconnection triggers the indoor unit to generate a corresponding fault code and send it to the user terminal associated with the indoor unit, and controls the fan in the indoor unit to operate, thereby supplying air to the air-conditioned operating space. It also triggers the linked fan to operate, adjusting the refrigerant concentration in the air-conditioned operating space to a target concentration value. The refrigerant detector is connected to both the indoor unit and the linked fan.

[0060] Obtain user information regarding triggering the reset button;
[0061] In response to the user's operation of triggering the reset button, the buzzer and alarm light installed in the refrigerant detector are controlled to stop operating within a target time period. Within the target time period, the refrigerant concentration in the air-conditioned operating space is continuously detected to obtain the current real-time refrigerant concentration data. If the real-time refrigerant concentration data exceeds the refrigerant concentration threshold, the buzzer installed in the refrigerant detector is triggered again to emit a periodic beep and the alarm light installed in the refrigerant detector is triggered to flash periodically.
[0062] According to the air conditioning refrigerant leak detection and processing device provided in this application, after controlling the buzzer installed in the refrigerant detector to emit a periodic buzzing sound and controlling the alarm light installed in the refrigerant detector to flash periodically, the air conditioning refrigerant leak processing unit is further configured to:

If the refrigerant concentration data in the air-conditioning operating space reaches the target concentration value, the buzzer and alarm light installed in the refrigerant detector are controlled to stop operating within the target time period, and the transmission signal connection between the refrigerant detector and the indoor unit of the air conditioner and the linked fan is restored.
[0064] The air conditioning refrigerant leakage detection and processing device provided in this application further includes: a fault detection unit, configured to: acquire communication data collected by the communication sensor inside the refrigerant detector; compare and analyze the communication data with preset standard communication data to obtain a communication fault detection result of the refrigerant detector; and / or trigger the self-test program inside the refrigerant detector to obtain the operating data of the refrigerant detector; compare and analyze the operating data with preset standard operating data to obtain a self-test anomaly detection result of the refrigerant detector; and / or record the actual usage time of the refrigerant detector based on the timer inside the refrigerant detector; compare and analyze the actual usage time with a preset standard usage time to obtain a service life detection result of the refrigerant detector.
[0065] Based on the communication fault detection results, the self-test anomaly detection results, and the service life detection results, the buzzer installed in the refrigerant detector is triggered to emit a corresponding mode of buzzing, and the alarm light installed in the refrigerant detector is controlled to flash in a corresponding mode.

[0067] If the communication fault detection result is an abnormal detection result, the buzzer installed in the refrigerant detector is triggered to emit a first mode of buzzing and the alarm light installed in the refrigerant detector is triggered to perform a first mode of flashing.
[0068] If the self-test anomaly detection result is an anomaly, the buzzer installed in the refrigerant detector is triggered to emit a second mode of buzzing, and the alarm light installed in the refrigerant detector is triggered to perform a second mode of flashing.
[0069] If the service life test result is abnormal, the buzzer installed in the refrigerant detector is triggered to emit a third-mode buzzer and the alarm light installed in the refrigerant detector is triggered to flash in a third-mode.
[0070] The air conditioning refrigerant leakage detection and processing device provided in this application detects the refrigerant concentration in the air conditioning operating space to obtain the current refrigerant concentration data. When the refrigerant concentration data exceeds the refrigerant concentration threshold, it controls the disconnection of the transmission signal between the refrigerant detector and the indoor unit and / or the linked fan, respectively.

This effectively improves the flexibility and accuracy of air conditioning refrigerant leakage detection, and can quickly reduce the concentration of leaked refrigerant, thereby ensuring the user's safety.
