Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

[0021] The following Figures 1-4 describes the air-conditioning refrigerant leakage detection and treatment method and device of the present invention, and details its embodiments.

[0022] The following is a detailed description of the embodiments based on the air-conditioning system described in the present invention. As Figure 1As shown in the figure, it is a schematic structural diagram of the air-conditioning system provided by the present invention. The specific implementation process includes the following parts: an indoor unit 102, a linkage fan 103, and a refrigerant detector 101. The indoor unit 102 and the linkage fan 103 are both communicatively connected to the refrigerant detector 101. The refrigerant detector 101 is externally placed, and the refrigerant detector 101 detects the refrigerant leakage situation and switches the communication state with the indoor unit 102 and / or the linkage fan 103 according to the detection result. In addition, the air-conditioning system may further include: an alarm device, the alarm device is electrically connected to the refrigerant detector 101, and when the refrigerant detector 101 detects that the refrigerant exceeds the refrigerant concentration threshold, the alarm device performs a periodic alarm action; and / or, a reset button, the reset button is electrically connected to the alarm device, and when the reset button is triggered, the reset button controls the alarm device to stop alarming within the first time period T1.

[0023] Based on the air-conditioning refrigerant leakage detection and processing method described in the present invention below, its embodiments will be described in detail. As Figure 2 shown in the figure, it is one of the schematic flowcharts of the air-conditioning refrigerant leakage detection and processing method provided by the present invention. The specific implementation process includes the following steps: Step 201: Detect the refrigerant concentration in the air-conditioning operation space to obtain the current refrigerant concentration data.

[0024] In the embodiment of the present invention, the refrigerant concentration in the air-conditioning operation space can be detected by a refrigerant detector to obtain the current refrigerant concentration data. The refrigerant detector is located outside the air-conditioning and has an independent power supply device, and internally includes a processor module, a storage module, and a refrigerant concentration detection sensor. Since the refrigerant detector is arranged independently of the air-conditioning, the layout position is more flexible. The refrigerant can be R32 refrigerant, R22 refrigerant, etc. used in the air-conditioning, and no specific limitation is made here.

[0025] Step 202: In the case where the refrigerant concentration data exceeds the refrigerant concentration threshold, control to cut off the transmission signal connection between the refrigerant detector and the air-conditioning indoor unit and / or the linkage fan respectively, so as to control the operation of the fan in the air-conditioning indoor unit or the linkage fan by cutting off the transmission signal, so as to adjust the refrigerant concentration in the air-conditioning operation space to the target concentration value.

[0026] In an embodiment of the present invention, after the refrigerant detector obtains the current refrigerant concentration data, when it determines that the refrigerant concentration data exceeds the refrigerant concentration threshold, it can control the disconnection of the transmission signal connections between the refrigerant detector and the air conditioner indoor unit and the linked fan respectively. For example, it can control the short-circuit of the transmission signal connections between the refrigerant detector and the air conditioner indoor unit and the linked fan respectively, so as to trigger the air conditioner indoor unit to generate corresponding fault codes and send them to the user terminal associated with the air conditioner by cutting off the transmission signal, and control the operation of the fan in the air conditioner indoor unit to send air into the air conditioner operation space, disturbing the leaked refrigerant in the air conditioner operation space; and trigger the operation of the linked fan to exhaust to the outside, so as to adjust the refrigerant concentration in the air conditioner operation space to the target concentration value; wherein, the refrigerant detector is respectively connected to the air conditioner indoor unit and the linked fan. The present invention forms an air flow disturbance by the operation of the fan in the air conditioner indoor unit to send air into the air conditioner operation space, and at the same time controls the operation of the linked fan independent of the outside of the air conditioner to exhaust to the outside, so as to discharge the leaked refrigerant to the outside in time, and can better achieve the effect of quickly reducing the concentration of the leaked refrigerant, thus ensuring the user's use safety.

[0027] In addition, in an embodiment of the present invention, after obtaining the current refrigerant concentration data, when the refrigerant concentration data exceeds the refrigerant concentration threshold, it can also control the buzzer set in the refrigerant detector to emit periodic beeps and control the alarm light set in the refrigerant detector to flash periodically. In addition, after controlling the disconnection of the transmission signals between the refrigerant detector and the air conditioner indoor unit and the linked fan respectively, it can also trigger the sound and light alarm in the air conditioner indoor unit to send out alarm information, so as to more effectively and timely remind the user that there is a refrigerant leakage situation.

[0028] In order to improve the user experience and avoid interference to the user caused by continuous beeping of the buzzer and flashing of the alarm light, after controlling the buzzer set in the refrigerant detector to emit periodic beeps and controlling the alarm light set in the refrigerant detector to flash periodically, the present invention can also obtain the operation information of the user triggering the reset button. By responding to the operation information of the user triggering the reset button, it controls the buzzer and the alarm light set in the refrigerant detector to stop operating within a target time period (such as 2 minutes), and to ensure use safety, it immediately continues to detect the refrigerant concentration in the air conditioner operation space within the target time period, further obtaining the current real-time refrigerant concentration data. If the real-time refrigerant concentration data still exceeds the refrigerant concentration threshold, it is necessary to trigger again to control the buzzer set in the refrigerant detector to emit periodic beeps and control the alarm light set in the refrigerant detector to flash periodically, so as to remind the user to take treatment measures as soon as possible.

[0029] In addition, after controlling the buzzer provided in the refrigerant detector to emit periodic beeps and controlling the alarm light provided in the refrigerant detector to blink periodically, the present invention can continue to detect the refrigerant concentration in the air-conditioning operation space. When it is detected that the refrigerant concentration data in the air-conditioning operation space reaches the target concentration value, it is determined that the refrigerant leakage problem has been handled. Furthermore, the buzzer and the alarm light provided in the refrigerant detector are controlled to stop operating within the target time period, and the transmission signal connections between the refrigerant detector and the indoor unit of the air conditioner and the linkage fan are controlled to be restored, so as to continue to monitor the refrigerant leakage problem during subsequent air-conditioning use and improve the detection accuracy.

[0030] That is, if the refrigerant detector detects that the refrigerant concentration in the air exceeds the standard, its buzzer emits periodic beeps and the corresponding alarm light blinks periodically. At this time, the refrigerant detector will send an instruction to cut off the signals with the indoor unit of the air conditioner / air-conditioning valve box and the linkage fan. The indoor unit of the air conditioner synchronously gives out sound and light alarms, blinks the corresponding fault codes and runs at high speed. If the user connects the linkage fan, the linkage fan synchronously performs the high-speed operation. If the user thinks that the noise of the refrigerant detector is too loud, the user can click the reset button on the refrigerant detector itself. In the next two minutes, the buzzer and the corresponding fault light will go out for two minutes. During this period, the refrigerant detector works normally and still keeps cutting off the signals with the indoor unit of the air conditioner / valve box and the linkage fan. If the concentration is still detected to be abnormal after two minutes, the sound and light alarms are restored. Only when the refrigerant detector detects that the refrigerant concentration drops below the set value, the sound and light alarms disappear and the signals between the refrigerant detector and the indoor unit of the air conditioner / air-conditioning valve box and the linkage fan are restored.

[0031] In the embodiment of the present invention, communication data collected by a communication sensor in the refrigerant detector is obtained, and based on a comparison and analysis of the communication data with preset standard communication data, a communication fault detection result of the refrigerant detector is obtained; and / or, a self-check program in the refrigerant detector is triggered to run to obtain operation data of the refrigerant detector, and based on a comparison and analysis of the operation data with preset standard operation data, a self-check anomaly detection result of the refrigerant detector is obtained; and / or, the actual usage time of the refrigerant detector is recorded based on a timer in the refrigerant detector, and the actual usage time is compared and analyzed with a preset standard usage time to obtain a service life detection result of the refrigerant detector. Based on the communication fault detection result, the self-check anomaly detection result, and the service life detection result, the buzzer provided in the refrigerant detector is triggered to emit beeps in a corresponding mode and the alarm light provided in the refrigerant detector is controlled to blink in a corresponding mode. Thus, it is convenient for the user to determine the operation state of the refrigerant detector.

[0032] Among them, in the process of triggering to control the buzzer arranged in the refrigerant detector to emit a buzzer of a corresponding mode and control the alarm lamp arranged in the refrigerant detector to perform a flash of a corresponding mode based on the communication fault detection result, the self-check abnormal detection result, and the service life detection result, it includes: when the communication fault detection result is an abnormal detection result, triggering to control the buzzer arranged in the refrigerant detector to emit a buzzer of a first mode and control the alarm lamp (i.e., the LED lamp) arranged in the refrigerant detector to perform a flash of the first mode, and the control parameters in this first mode are the parameter contents corresponding to No. 2 in the following table; when the self-check abnormal detection result is an abnormal detection result, triggering to control the buzzer arranged in the refrigerant detector to emit a buzzer of a second mode and control the alarm lamp arranged in the refrigerant detector to perform a flash of the second mode, and the control parameters in this second mode are the parameter contents corresponding to No. 3 in the following table; when the service life detection result is an abnormal detection result, triggering to control the buzzer arranged in the refrigerant detector to emit a buzzer of a third mode and control the alarm lamp arranged in the refrigerant detector to perform a flash of the third mode, and the control parameters in this third mode are the parameter contents corresponding to No. 4 in the following table. Thus, it is convenient for users to quickly identify different fault states of the refrigerant detector through the differences in flashing and buzzing.

[0033] For example, the refrigerant detector monitors the refrigerant concentration in the air in real time. If the refrigerant detector itself has faults such as communication faults, self-check abnormalities, and expired lifespan, the buzzer of the refrigerant detector itself emits a periodic buzzer and the corresponding alarm lamp flashes periodically. At this time, the signals of the indoor unit of the air conditioner / the air conditioner valve box and the linkage fan are normal. If the user thinks that the noise of the refrigerant detector is too loud, the user can click the reset button on the refrigerant detector itself. In the next two minutes, the buzzer and the corresponding fault lamp will go out for two minutes. During this period, the refrigerant detector works normally. If an abnormality is still detected two minutes later, the sound and light alarm will be restored.

[0034] The present invention solves the problem that when air-conditioning refrigerant leakage is found in a closed space, through sound and light alarm and control of the operating state of the unit, it realizes reminding people in the closed space of air-conditioning refrigerant leakage and linking the unit to reduce the air-conditioning refrigerant concentration in the environment. As Figure 3As shown in the figure, first, a refrigerant detector monitors the refrigerant concentration in the air to continuously monitor the concentration of the air conditioner refrigerant in the air. Second, if the refrigerant detector detects that the refrigerant concentration in the air exceeds the standard or there is an abnormality in itself, the indicator light and buzzer of the refrigerant detector will alarm at a fixed frequency and decibel level; if it is detected that the refrigerant leakage reaches the critical point, the signal connection with the air conditioner indoor unit / air conditioner valve box and the linked fan will be cut off for linkage. By closing the valve and running the fan in the air conditioner indoor unit at high speed, the refrigerant concentration in the air can be reduced, and the explosion risk can be reduced. The existing built-in detectors can only be installed in the indoor unit or valve box, and can only be linked with the indoor unit. The installation position is relatively single, and it cannot be linked with the exhaust fan, etc. At the same time, it depends on the air conditioner indoor unit and cannot achieve its own monitoring and alarm. It is not suitable for refrigerant detection in multi-tenant scenarios either. When the built-in detector cannot monitor after the air conditioner refrigerant leakage occurs, the refrigerant detector conducts real-time monitoring and alarm of the refrigerant leakage through the flexibility of its independent power supply installation position.

[0035] The air conditioner refrigerant leakage detection and processing method provided by the present invention detects the refrigerant concentration in the air conditioner operation space to obtain the current refrigerant concentration data; in the case that the refrigerant concentration data exceeds the refrigerant concentration threshold, it controls to cut off the transmission signal connection between the refrigerant detector and the air conditioner indoor unit and / or the linked fan respectively, so as to control the operation of the fan in the air conditioner indoor unit or the linked fan by cutting off the transmission signal, and adjust the refrigerant concentration in the air conditioner operation space to the target concentration value. It effectively improves the flexibility and accuracy of air conditioner refrigerant leakage detection, can achieve the effect of quickly reducing the concentration of the leaked refrigerant, and thus ensures the user's safety in use.
