However, when the air conditioner installs and debugs the electronic expansion valve and replaces the electronic expansion valve after sales, it is often impossible to effectively control the electronic expansion valve because the actual opening direction of the new electronic expansion valve is different from that set by the system software. If the valve opening direction controlled by the software is opposite to the actual valve opening direction of the electronic expansion valve, it will cause the air conditioner to stop or be damaged.
由此可见,如何检测电子膨胀阀的实际开阀方向与系统预设方向一致成为了亟需解决的问题。It can be seen that how to detect that the actual valve opening direction of the electronic expansion valve is consistent with the system preset direction has become an urgent problem to be solved.

具体实施方式Detailed ways
为使本发明的上述目的、特征和优点能够更为明显易懂,对本发明的具体实施例做详细的说明。In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail.
实施例一:Embodiment one:
本实施例提供一种电子膨胀阀的安装检测方法,包括:当在空调系统中安装电子膨胀阀时;检测电子膨胀阀的高低压压比,根据高低压压比判断电子膨胀阀的实际开阀方向与空调系统的预设方向是否相同,以确定电子膨胀阀的安装方向是否正确。This embodiment provides an installation detection method for an electronic expansion valve, including: when an electronic expansion valve is installed in an air-conditioning system; detecting the high and low pressure ratio of the electronic expansion valve, and judging the actual opening of the electronic expansion valve according to the high and low pressure ratio Whether the direction is the same as the preset direction of the air conditioning system to determine whether the installation direction of the electronic expansion valve is correct.
在本实施例中,空调系统的预设方向是指空调系统对电子膨胀阀发出的开阀多少开度或是关阀多少开度的指令,即开阀多少开度是一个方向,对应电子膨胀阀的开度增大;关阀多少开度是一个方向,对应电子膨胀阀的开度减小。对应的,在指令下达至电子膨胀阀时,电子膨胀阀会相应地作出实际的开阀或是关阀动作,一旦电子膨胀阀的实际开阀方向与空调系统的预设方向相反,则会导致空调系统的预设方向为增大膨胀阀开度的方向,但是电子膨胀阀实际执行了关阀动作,此时电子膨胀阀开度减小,从而造成空调器的损坏。In this embodiment, the preset direction of the air-conditioning system refers to the command issued by the air-conditioning system to the electronic expansion valve to open the valve or close the valve, that is, the opening of the valve is a direction, corresponding to the electronic expansion valve. The opening of the valve increases; the opening of the valve is one direction, corresponding to the opening of the electronic expansion valve decreases. Correspondingly, when the command is sent to the electronic expansion valve, the electronic expansion valve will actually open or close the valve accordingly. Once the actual opening direction of the electronic expansion valve is opposite to the preset direction of the air conditioning system, it will cause The preset direction of the air conditioning system is to increase the opening of the expansion valve, but the electronic expansion valve actually performs a valve closing action, and the opening of the electronic expansion valve decreases at this time, resulting in damage to the air conditioner.
具体来说,即电子膨胀阀由步进电机通过调整上电顺序从而控制电子膨胀阀的开关阀方向,开阀方向表示电子膨胀阀的开度增大的方向,关阀方向表示电子膨胀阀开度减小的方向。本实施例中的安装检测方法具体适用于四相八拍步进电机控制的电子膨胀阀,四相八拍步进电机控制的电子膨胀阀包括两种上电顺序,其中,将第一种使得电子膨胀阀开阀的上电顺序规定为程序一,将第二种使得电子膨胀阀开阀的上电顺序规定为程序二,空调系统种通过步进电机执行程序一的开阀的上电顺序,实际对应的电子膨胀阀可能进行开阀操作或是关阀操作,同样的,空调系统种通过步进电机执行程序二的开阀的上电顺序,实际对应的电子膨胀阀可能进行开阀操作或是关阀操作,因此会导致电子膨胀阀的实际开阀方向与系统预设的方向不同。Specifically, the electronic expansion valve is controlled by the stepping motor by adjusting the power-on sequence to control the opening and closing direction of the electronic expansion valve. direction of decrease. The installation detection method in this embodiment is specifically applicable to the electronic expansion valve controlled by a four-phase eight-step stepping motor. The electronic expansion valve controlled by a four-phase eight-step stepping motor includes two power-on sequences, of which the first one makes The power-on sequence for opening the electronic expansion valve is defined as program 1, and the second power-on sequence for opening the electronic expansion valve is defined as program 2. The air-conditioning system executes the power-on sequence for valve opening of program 1 through the stepping motor , the actual corresponding electronic expansion valve may perform valve opening operation or valve closing operation. Similarly, the air conditioning system executes the power-on sequence of valve opening in program 2 through the stepping motor, and the actual corresponding electronic expansion valve may perform valve opening operation Or close the valve operation, which will cause the actual valve opening direction of the electronic expansion valve to be different from the system preset direction.
其中,当电子膨胀阀正常开启时,即空调系统的预设方向与电子膨胀阀的实际开阀方向一致时,空调系统中的低压压力会缓慢平衡,高低压压比会逐渐缩小直至平衡;但是,当空调系统的预设方向与电子膨胀阀的实际开阀方向相反,即空调系统下发开阀指令,但是电子膨胀阀实际进行了关阀操作,则此时在空调系统中会导致冷媒无法回流至压缩机,使得高低压压比过高,因此,通过检测电子膨胀阀启动后的高低压压比的值,即可判断电子膨胀阀的实际开阀方向是否与空调系统的的预设方向相同,从而决定是否需要对空调系统的预设方向进行调整,使得空调系统的发出开阀指令时,电子膨胀阀能够对应实现开阀操作。Among them, when the electronic expansion valve is normally opened, that is, when the preset direction of the air-conditioning system is consistent with the actual opening direction of the electronic expansion valve, the low-pressure pressure in the air-conditioning system will slowly balance, and the high-low pressure ratio will gradually decrease until it is balanced; but , when the preset direction of the air conditioning system is opposite to the actual valve opening direction of the electronic expansion valve, that is, the air conditioning system issues a valve opening command, but the electronic expansion valve actually performs a valve closing operation, then the refrigerant in the air conditioning system will not be able to The flow back to the compressor makes the high and low pressure ratio too high. Therefore, by detecting the value of the high and low pressure ratio after the electronic expansion valve is started, it can be judged whether the actual valve opening direction of the electronic expansion valve is consistent with the preset direction of the air conditioning system. Similarly, it is determined whether the preset direction of the air-conditioning system needs to be adjusted, so that when the air-conditioning system issues a valve-opening command, the electronic expansion valve can correspondingly realize the valve-opening operation.
其中,对应的,此安装检测方法适用于电子膨胀阀安装至空调系统时所需要进行的检测,包括但不限于电子膨胀阀进行调试、电子膨胀阀进行更换。Wherein, correspondingly, this installation detection method is applicable to the detection required when the electronic expansion valve is installed in the air conditioning system, including but not limited to the debugging of the electronic expansion valve and the replacement of the electronic expansion valve.

其中,当空调系统进行初次上电运行时,即表明此时电子膨胀阀同样为新装,此时便可直接执行本实施例中的安装检测方法,从而保证空调系统后续第二次运行启动电子膨胀阀不会发生错误。Among them, when the air conditioning system is powered on for the first time, it means that the electronic expansion valve is also newly installed at this time, and the installation detection method in this embodiment can be directly executed at this time, so as to ensure that the electronic expansion valve is activated for the second subsequent operation of the air conditioning system. The valve does not go wrong.
其中,当判断检测出空调系统并不是初次上电运行时,表明此空调系统已是第二次上电运行或是多次上电运行,表明此空调系统能够正常运行,此时便无需执行本实施例中的安装检测方法。Among them, when it is judged that the air conditioning system is not powered on for the first time, it indicates that the air conditioning system has been powered on for the second time or has been powered on for several times, indicating that the air conditioning system can operate normally, and there is no need to execute this procedure at this time.

在本实施例中,结合实施例一,第一目标控制模式对应程序一的上电顺序,程序一执行的是开启膨胀阀的指令,此时电子膨胀阀实际可能进行开阀操作,亦有可能进行关阀操作。In this embodiment, combined with Embodiment 1, the first target control mode corresponds to the power-on sequence of program 1, and program 1 executes the command to open the expansion valve. At this time, the electronic expansion valve may actually open the valve, and it is also possible Perform valve closing operation.
其中,第一条件具体为高低压压比大于等于第五预设值,其中第五预设值为空调系统的出厂默认值,可根据实际使用工况进行调整设置。具体的,在本实施例中,一般空调系统正常运行时,高低压压比不会超过8,因此,本实施例中,第五预设值优选为8。Wherein, the first condition is specifically that the high and low pressure ratio is greater than or equal to the fifth preset value, wherein the fifth preset value is a factory default value of the air conditioning system, which can be adjusted and set according to actual working conditions. Specifically, in this embodiment, when the general air conditioning system operates normally, the high and low pressure ratio will not exceed 8, therefore, in this embodiment, the fifth preset value is preferably 8.
具体的,第一目标控制模式为对应程序一的上电顺序,控制电子膨胀阀实际开阀或是关阀第一预设值的步数,且电子膨胀阀持续运行第一设定时间,第一预设值与第一设定时间为空调系统的出厂默认值,可根据实际使用工况进行调整设置。第一预设值在本实施例中优选为600,第一设定时间优选为30秒,从而能够保证电子膨胀阀在一定安全范围内运行,使得能够检测出电子膨胀阀的高低压压比的同时,电子膨胀阀不会损坏。Specifically, the first target control mode is to control the number of steps of the first preset value of the electronic expansion valve actually opening or closing the valve corresponding to the power-on sequence of program one, and the electronic expansion valve continues to run for the first set time. The first preset value and the first set time are factory default values of the air-conditioning system, and can be adjusted and set according to actual working conditions.

At the same time, the electronic expansion valve will not be damaged.
在第一目标控制模式的动作后,检测电子膨胀阀此时的高低压压比,将此时检测到的高低压压比设为第一压比,判断第一压比是否满足第一条件,若第一压比不满足第一条件,也即第一压比低于第五预设值,此时即表明空调系统正常运行,此时则第一目标控制模式对应的程序一的上电顺序能够实现电子膨胀阀的实际开阀,即表明此时电子膨胀阀的实际开阀方向与空调系统的预设方向相同,此时电子膨胀阀执行第二目标控制模式的动作。After the action of the first target control mode, detect the high and low pressure ratio of the electronic expansion valve at this time, set the detected high and low pressure ratio as the first pressure ratio, and judge whether the first pressure ratio satisfies the first condition, If the first pressure ratio does not meet the first condition, that is, the first pressure ratio is lower than the fifth preset value, it means that the air conditioning system is running normally. At this time, the power-on sequence of program one corresponding to the first target control mode Realizing the actual opening of the electronic expansion valve means that the actual opening direction of the electronic expansion valve is the same as the preset direction of the air conditioning system, and the electronic expansion valve executes the action of the second target control mode.
具体来说,第二目标控制模式为记录程序一为电子膨胀阀的实际开阀方向的原程序,同时控制电子膨胀阀关阀第二预设值的步数,并持续运行第二预设时间,之后重启电子膨胀阀。第二预设值与第二设定时间为空调系统的出厂默认值,可根据实际使用工况进行调整设置。第二预设值在本实施例中优选为600,第二设定时间优选为15秒。Specifically, the second target control mode is to record program one as the original program of the actual valve opening direction of the electronic expansion valve, and at the same time control the number of steps of the second preset value of the electronic expansion valve closing valve, and continue to run for the second preset time , and then restart the electronic expansion valve.

其中,当电子膨胀阀的高低压压比满足第一条件时,表明此时第一压比大于等于第五预设值,此时空调系统运行异常,此时第一目标控制模式对应的程序一的上电顺序不能实现电子膨胀阀的实际开阀,即表明此时电子膨胀阀的实际开阀方向与空调系统的预设方向相反,此时电子膨胀阀接着执行第三目标控制模式的动作。Wherein, when the high-low pressure ratio of the electronic expansion valve satisfies the first condition, it indicates that the first pressure ratio is greater than or equal to the fifth preset value at this time, and the air-conditioning system is operating abnormally at this time, and the program corresponding to the first target control mode is The power-on sequence cannot realize the actual opening of the electronic expansion valve, which means that the actual opening direction of the electronic expansion valve is opposite to the preset direction of the air conditioning system. At this time, the electronic expansion valve will then perform the action of the third target control mode.

Specifically, in this embodiment, when the general air-conditioning system is running normally, the high and low pressure ratio will not exceed 8. Therefore, in this embodiment, the sixth preset value is preferably 8.
具体来说,判断第二压比是否满足第二条件,若第二压比不满足第二条件,也即第二压比低于第六预设值,此时即表明空调系统正常运行,此时则第二目标控制模式对应的程序二的上电顺序能够实现电子膨胀阀的实际开阀,即表明此时电子膨胀阀的实际开阀方向与空调系统的预设方向相同。Specifically, it is judged whether the second pressure ratio satisfies the second condition. If the second pressure ratio does not meet the second condition, that is, the second pressure ratio is lower than the sixth preset value, it indicates that the air conditioning system is operating normally. At this time, the power-on sequence of program 2 corresponding to the second target control mode can realize the actual opening of the electronic expansion valve, which means that the actual opening direction of the electronic expansion valve is the same as the preset direction of the air conditioning system.
具体来说,第四目标控制模式为记录程序二为电子膨胀阀的实际开阀方向的原程序,同时控制电子膨胀阀关阀第四预设值的步数,并持续运行第四预设时间,之后重启电子膨胀阀。第四预设值与第四设定时间为空调系统的出厂默认值,可根据实际使用工况进行调整设置。第四预设值在本实施例中优选为600,第四设定时间优选为15秒。Specifically, the fourth target control mode is the original program in which the recording program 2 is the actual valve opening direction of the electronic expansion valve, and at the same time controls the number of steps of the fourth preset value of the electronic expansion valve closing valve, and continues to run for the fourth preset time , and then restart the electronic expansion valve. The fourth preset value and the fourth set time are factory default values of the air-conditioning system, which can be adjusted and set according to actual working conditions. The fourth preset value is preferably 600 in this embodiment, and the fourth preset time is preferably 15 seconds.

本实施例中,若判断此时高低压压比满足第二条件,则停止第三目标控制模式并进行报错。In this embodiment, if it is determined that the high and low pressure ratios meet the second condition at this time, the third target control mode is stopped and an error is reported.
在本实施例中,具体说明了若第二压比满足第二条件时,电子膨胀阀需要进行的动作。In this embodiment, the action that the electronic expansion valve needs to perform when the second pressure ratio satisfies the second condition is specifically described.
若第二压比满足第二条件,则表明此时第二压比大于等于第六预设值,表明空调系统此时无法正常运行。此时电子膨胀阀的实际开阀方向无法匹配第一目标控制模式以及第三目标控制模式,因此可说明电子膨胀阀发生故障,亦或是本实施例中的控制模式不能够兼容本实施例的电子膨胀阀,从而对电子膨胀阀进行报错,并停机检测。If the second pressure ratio satisfies the second condition, it indicates that the second pressure ratio is greater than or equal to the sixth preset value, indicating that the air conditioning system cannot operate normally at this time.
