[0041] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0042] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0043] The following description, in conjunction with the accompanying drawings, details the gas leak detection method, gas leak detection device, gas leak detection system, electronic equipment, and readable storage medium for a gas-fired heat pump air conditioner provided in this application, through specific embodiments and application scenarios.

[0044] Among them, the gas leak detection method for gas heat pump air conditioners can be applied to the terminal, and can be executed by the hardware or software in the terminal.

[0045] The terminal includes, but is not limited to, portable communication devices such as mobile phones or tablets with touch-sensitive surfaces (e.g., touchscreen displays and / or touchpads). It should also be understood that, in some embodiments, the terminal may not be a portable communication device, but rather a desktop computer with touch-sensitive surfaces (e.g., touchscreen displays and / or touchpads).

[0046] The following embodiments describe a terminal including a display and a touch-sensitive surface. However, it should be understood that the terminal may include one or more other physical user interface devices such as a physical keyboard, mouse, and joystick.

[0047] The gas leak detection method for a gas heat pump air conditioner provided in this application embodiment can be executed by an electronic device or a functional module or entity in an electronic device that can implement the gas leak detection method for the gas heat pump air conditioner. The electronic devices mentioned in this application embodiment include, but are not limited to, mobile phones, tablets, computers, cameras, and wearable devices. The following uses an electronic device as the execution subject to illustrate the gas leak detection method for a gas heat pump air conditioner provided in this application embodiment.

[0048] like Figure 1 As shown, the gas leak detection method for the gas heat pump air conditioner includes steps 110 and 120.

[0049] Step 110: Obtain the current gas status parameters of the gas inlet of the gas heat pump air conditioner 300, and obtain the current unit operating status parameters of the gas heat pump unit of the gas heat pump air conditioner 300.

[0050] In this step, the current gas state parameters at the gas inlet of the gas heat pump air conditioner 300 are obtained. A sensor can be installed at the flexible connecting pipe 340 of the gas inlet of the gas heat pump air conditioner 300 to measure the current gas state parameters in real time.

[0051] Correspondingly, sensors can be installed at the gas heat pump unit to measure the current operating status parameters of the gas heat pump air conditioner 300 in real time during operation.

[0052] Step 120: Compare the current gas status parameters with the target gas status parameters, and compare the current unit operating status parameters with the target unit operating status parameters to obtain the gas leak detection results of the gas heat pump air conditioner 300.

[0053] Among them, the target gas state parameters and the target unit operating state parameters are the preset state parameters of the gas heat pump air conditioner 300 when it is operating normally without leakage.

[0054] The gas leak detection result of the gas heat pump air conditioner 300 can indicate whether there is a gas leak or no gas leak. The gas leak detection result can also include the possible area of ​​gas leak.

[0055] In this embodiment, the current gas state parameters and the target gas state parameters are compared, and the current unit operating state parameters and the target unit operating state parameters are compared. Based on the comparison results of the two state parameters, it is determined whether the gas in the gas heat pump air conditioner 300 has leaked.

[0056] It should be noted that when the gas heat pump air conditioner 300 is supplying gas normally, the gas state parameters at the gas inlet and the unit operating parameters of the gas heat pump unit remain within a relatively stable range. Target gas state parameters and target unit operating parameters can be preset in the gas heat pump air conditioner 300 system and compared in real time with the actual current gas state parameters and the current unit operating parameters. The difference between the two can be used to determine whether there is a gas leak.

[0057] In this embodiment, it is possible to determine in real time whether there is a gas leak in the gas heat pump air conditioner 300. When it is determined that there is a gas leak in the gas heat pump air conditioner 300, it can issue an early warning and take corresponding protective actions in a timely manner, thereby improving the safety of the gas heat pump air conditioner 300.

[0058] According to the gas leak detection method of the gas heat pump air conditioner provided in the embodiments of this application, the gas state parameters and unit operating state parameters are detected in real time and compared with preset state parameters to determine whether the gas heat pump air conditioner 300 has a gas leak, thereby improving the safety of the gas heat pump air conditioner 300.

[0059] In some embodiments, step 120, comparing the current gas state parameters with the target gas state parameters, and comparing the current unit operating state parameters with the target unit operating state parameters to obtain the gas leak detection result of the gas heat pump air conditioner 300, may include:

[0060] If the difference between the current gas state parameters and the target gas state parameters is outside the first target range, the gas leak detection result of the gas heat pump air conditioner 300 is obtained as a gas leak.

[0061] And / or, if the difference between the current unit operating status parameters and the target unit operating status parameters is determined to be outside the second target range, the gas leak detection result of the gas heat pump air conditioner 300 is obtained as a gas leak.

[0062] In this embodiment, the difference between the current gas state parameter and the target gas state parameter is calculated, and the difference is compared with a preset first target range. When it is determined that the difference is outside the first target range, it can be determined that the gas heat pump air conditioner 300 has a gas leak.

[0063] For example, if the first target range is (-5, 5), and the difference between the current gas state parameter and the target gas state parameter is 3, it is determined that the gas heat pump air conditioner 300 has no gas leakage. If the difference between the current gas state parameter and the target gas state parameter is -7, it is determined that the gas heat pump air conditioner 300 has a gas leakage.

[0064] Calculate the difference between the current unit operating status parameters and the target unit operating status parameters, and compare the difference with the preset second target range. When it is determined that the difference is outside the second target range, it can be judged that the gas heat pump air conditioner 300 has a gas leak.

[0065] For example, if the second target range is (-3, 3), and the difference between the current unit operating status parameter and the target unit operating status parameter is 2, it is determined that the gas heat pump air conditioner 300 has no gas leakage. If the difference between the current unit operating status parameter and the target unit operating status parameter is -5, it is determined that the gas heat pump air conditioner 300 has gas leakage.

[0066] It should be noted that, in actual implementation, a gas leak can be determined when the difference between the current gas state parameters and the target gas state parameters is outside the first target range, or when the difference between the current unit operating state parameters and the target unit operating state parameters is outside the second target range. Alternatively, a gas leak can be determined when the difference between the current gas state parameters and the target gas state parameters is outside the first target range and the difference between the current unit operating state parameters and the target unit operating state parameters is outside the second target range.

[0067] In some embodiments, the current gas state parameter is the current gas pressure at the gas inlet, and the target gas state parameter is the target gas pressure at the gas inlet.

[0068] In this embodiment, the current gas pressure at the gas inlet can be compared with the target gas pressure, and the difference between the two can be used to determine whether a gas leak has occurred.

[0069] Understandably, when there is a leak at the gas inlet of the gas heat pump air conditioner 300, the leak can be confirmed by the gas pressure at that location. A pressure sensor 330 can be installed at this location to monitor the current gas pressure at the gas inlet in real time.

[0070] In some embodiments, the current unit operating status parameters include at least one of the current high and low pressures and the current exhaust and return gas temperatures of the gas heat pump unit, and the target unit operating status parameters include at least one of the target high and low pressures and the target exhaust and return gas temperatures of the gas heat pump unit.

[0071] The current high and low pressures of a gas heat pump unit include the current high pressure and the current low pressure. These pressures can be monitored in real time by installing a pressure gauge valve in the gas heat pump unit.

[0072] The current exhaust and return gas temperatures of a gas heat pump unit include the current exhaust temperature and the current return gas temperature. These temperatures can be monitored in real time by installing temperature sensors in the gas heat pump unit.

[0073] Under normal gas supply conditions, the gas pressure at the gas inlet of the 300 gas heat pump air conditioner remains within a stable range, and the unit's operating parameters, such as high and low pressure and exhaust / return gas temperature, also remain within a reasonable and stable range.

[0074] In this embodiment, target gas pressure, target high and low pressure, and target exhaust and return gas temperature can be preset in the gas heat pump air conditioner 300 system. These can be compared in real time with the actual current gas pressure, current high and low pressure, and current exhaust and return gas temperature. The difference between the two can be used to determine whether there is a leakage.

[0075] In some embodiments, after obtaining the gas leak detection result of the gas heat pump air conditioner 300 in step 120, the gas leak detection method of the gas heat pump air conditioner may further include:

[0076] If the gas leak detection result of the gas heat pump air conditioner 300 is confirmed to be a gas leak, the gas supply to the gas heat pump air conditioner 300 shall be shut off and the gas heat pump air conditioner 300 shall be subjected to gas recovery treatment.

[0077] In this embodiment, the gas heat pump air conditioner 300 determines that a gas leak has occurred, shuts off the gas supply to the gas heat pump air conditioner 300 to prevent further gas leakage, and performs gas recovery treatment on the gas heat pump air conditioner 300 to recover the leaked gas, reduce the concentration of gas in the environment, and eliminate the risk of explosion.

[0078] For example, such as Figure 3 As shown, when the gas leak detection result of the gas heat pump air conditioner 300 is determined to be a gas leak, the first intake solenoid valve 310 and the second intake solenoid valve 320 are controlled to close, thus shutting off the gas supply to the gas heat pump air conditioner 300.

[0079] The gas heat pump air conditioner 300 is subjected to gas recovery treatment. The intake solenoid valve 351 and intake pump 352 are opened to continuously extract gas from the leak point and store it in the gas storage tank 353. This reduces the gas content at the leak point so that it does not reach the concentration required for combustion and explosion, thereby improving the safety and reliability of the gas leak detection system of the gas heat pump air conditioner.

[0080] The gas leak detection method for a gas-fired heat pump air conditioner provided in this application embodiment can be executed by a gas leak detection device for the gas-fired heat pump air conditioner. This application embodiment uses the gas leak detection device for the gas-fired heat pump air conditioner executing the gas leak detection method as an example to illustrate the gas leak detection device for the gas-fired heat pump air conditioner provided in this application embodiment.

[0081] This application also provides a gas leak detection device for a gas heat pump air conditioner.

[0082] like Figure 2 As shown, the gas leak detection device for this gas heat pump air conditioner includes:

[0083] The acquisition module 210 is used to acquire the current gas status parameters of the gas inlet of the gas heat pump air conditioner 300 and the current unit operating status parameters of the gas heat pump unit of the gas heat pump air conditioner 300.

[0084] The processing module 220 is used to compare the current gas state parameters with the target gas state parameters, and to compare the current unit operating state parameters with the target unit operating state parameters, so as to obtain the gas leak detection results of the gas heat pump air conditioner 300.

[0085] According to the gas leak detection device of the gas heat pump air conditioner provided in the embodiment of this application, the gas state parameters and unit operating state parameters are detected in real time and compared with preset state parameters to determine whether the gas heat pump air conditioner 300 has a gas leak, thereby improving the safety of the gas heat pump air conditioner 300.

[0086] In some embodiments, the processing module 220 is used to obtain the gas leak detection result of the gas heat pump air conditioner 300 as a gas leak when it is determined that the difference between the current gas state parameter and the target gas state parameter is outside the first target range.

[0087] And / or, if the difference between the current unit operating status parameters and the target unit operating status parameters is determined to be outside the second target range, the gas leak detection result of the gas heat pump air conditioner 300 is obtained as a gas leak.

[0088] In some embodiments, the current gas state parameter is the current gas pressure at the gas inlet, and the target gas state parameter is the target gas pressure at the gas inlet.

[0089] In some embodiments, the current unit operating status parameters include at least one of the current high and low pressures and the current exhaust and return gas temperatures of the gas heat pump unit, and the target unit operating status parameters include at least one of the target high and low pressures and the target exhaust and return gas temperatures of the gas heat pump unit.

[0090] In some embodiments, the processing module 220 is further configured to shut off the gas supply to the gas heat pump air conditioner 300 and perform gas recovery treatment on the gas heat pump air conditioner 300 if the gas leak detection result of the gas heat pump air conditioner 300 is determined to be a gas leak.

[0091] The gas leak detection device for the gas heat pump air conditioner in this application embodiment can be an electronic device or a component of an electronic device, such as an integrated circuit or a chip. The electronic device can be a terminal or other devices besides a terminal. For example, the electronic device can be a mobile phone, tablet computer, laptop computer, PDA, in-vehicle electronic device, mobile internet device (MID), augmented reality (AR) / virtual reality (VR) device, robot, wearable device, ultra-mobile personal computer (UMPC), netbook, or personal digital assistant (PDA), etc. It can also be a server, network attached storage (NAS), personal computer (PC), television (TV), ATM, or self-service machine, etc. This application embodiment does not specifically limit the specific device.

[0092] The gas leak detection device for the gas-fired heat pump air conditioner in this embodiment can be a device with an operating system. This operating system can be Android, iOS, or other possible operating systems; this embodiment does not specifically limit its use.

[0093] The gas leak detection device for gas-fired heat pump air conditioners provided in this application embodiment can achieve... Figure 1 The various processes implemented in the method implementation examples will not be described again here to avoid repetition.

[0094] This application also provides a gas leak detection system for a gas heat pump air conditioner.

[0095] The gas leak detection system of the gas heat pump air conditioner in this application embodiment includes: a gas inlet pipe, a gas heat pump air conditioner 300, a first sensor, a second sensor, and a controller.

[0096] The gas heat pump air conditioner 300 is connected to a gas intake pipe, which is used to supply gas to the gas heat pump air conditioner 300.

[0097] The first sensor is located at the connection between the gas heat pump air conditioner 300 and the gas intake pipe. The first sensor is used to collect the current gas status parameters of the gas intake of the gas heat pump air conditioner 300.

[0098] In some embodiments, the first sensor may be a pressure sensor 330. The pressure sensor 330 is installed on the flexible connecting pipe 340 at the connection between the gas heat pump air conditioner 300 and the gas intake pipe to detect the current gas pressure at the gas intake in real time.

[0099] The second sensor is installed in the gas heat pump air conditioner 300. The second sensor is used to collect the current unit operating status parameters of the gas heat pump unit of the gas heat pump air conditioner 300.

[0100] The controller is electrically connected to the first sensor and the second sensor. The controller is used to obtain the gas leak detection result of the gas heat pump air conditioner 300 based on the gas leak detection method of the gas heat pump air conditioner described above.

[0101] According to the gas leak detection system of the gas heat pump air conditioner provided in the embodiment of this application, the gas state parameters and unit operating state parameters are detected in real time and compared with preset state parameters to determine whether the gas heat pump air conditioner 300 has a gas leak, thereby improving the safety of the gas heat pump air conditioner 300.

[0102] In some embodiments, the gas leak detection system of a gas heat pump air conditioner may further include a gas leak handling device.

[0103] In this embodiment, the gas leak handling device includes an intake solenoid valve 351, an intake pump 352, and a gas storage tank 353 connected in sequence. The gas leak handling device is connected to a controller, which is used to drive the intake solenoid valve 351 and the intake pump 352 to extract the leaked gas and store the leaked gas in the gas storage tank 353.

[0104] The following is a specific example.

[0105] like Figure 3 As shown, the gas leak detection system of the gas heat pump air conditioner includes components such as a gas heat pump air conditioner 300, a first intake solenoid valve 310, a second intake solenoid valve 320, a pressure sensor 330, a flexible connecting pipe 340, a suction solenoid valve 351, a suction pump 352, a gas storage tank 353, a gas meter 360, and a main gas supply pipeline 370.

[0106] During normal operation, the first intake solenoid valve 310 and the second intake solenoid valve 320 are open, while the intake solenoid valve 351 and the intake pump 352 are closed. Gas flows from the main gas supply pipeline 370 through the gas meter 360, the flexible connection pipe 340, the first intake solenoid valve 310, and the second intake solenoid valve 320, and enters the gas heat pump air conditioner 300 normally. The gas heat pump air conditioner 300 operates normally.

[0107] When the flexible connecting pipe 340 is damaged due to installation, external force, or other reasons, resulting in gas leakage, the gas pressure detected by the pressure sensor 330 and the unit operating status parameters inside the gas heat pump unit change. The two actual status parameters are compared with the preset status parameters, and when a leak is detected, a leak fault is reported.

[0108] In this embodiment, when a leak occurs, the first intake solenoid valve 310 and the second intake solenoid valve 320 are closed, while the intake solenoid valve 351 and the intake pump 352 are opened to continuously extract gas from the leak point and store it in the gas storage tank 353. This reduces the gas content at the leak point so that it does not reach the concentration required for combustion and explosion, thereby improving the safety and reliability of the gas leak detection system of the gas heat pump air conditioner.

[0109] The gas leak detection system of the gas heat pump air conditioner in this application adds a gas leak handling device to the main gas supply pipeline, which can effectively avoid serious consequences caused by gas leaks, simplify the system control program, and is suitable for widespread application.
