技术领域Technical field

本公开涉及新风***技术领域，尤其涉及一种新风***故障判断方法、装置和告警***。The present disclosure relates to the field of fresh air system technology, and in particular, to a fresh air system fault determination method, device and alarm system.

背景技术Background technique

现有新风***一般只有除湿或净化等简单功能，而少数新风空调器同时具备制冷和制热功能，制冷剂是保证新风***制冷和制热功能正常执行的必要因素之一。The existing fresh air system generally has only simple functions such as dehumidification or purification, and a few fresh air conditioners have both cooling and heating functions. The refrigerant is one of the necessary factors to ensure the normal operation of the refrigeration and heating functions of the fresh air system.

在制冷剂泄露过程中，由于新风***的制冷或者制热是一个缓慢的过程，用户短时间内无法感知***是否出现故障，只有过很长时间后，用户发现***仍然没有达到制冷或制热的效果时，才会意识到***出现了故障，但是此时用户还是无法得知故障原因，只能由设备维修人员对***进行检测后，才能判断本次故障是否是由于制冷剂泄露而引起的。During the refrigerant leakage process, because the cooling or heating of the fresh air system is a slow process, the user cannot sense whether the system has failed in a short time. Only after a long time, the user finds that the system still does not reach the cooling or heating. When the effect is realized, it will be realized that the system has a fault, but at this time, the user still cannot know the cause of the fault. Only after the equipment maintenance personnel have tested the system, can it be judged whether the fault is caused by the leakage of the refrigerant.

具体实施方式detailed description

下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。The technical solutions in the embodiments of the present disclosure are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present disclosure. It is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without departing from the inventive scope are the scope of the disclosure.

针对于相关技术中，在新风***处于缺少制冷剂状态下运行时，用户难以在短时间内发现该故障，而影响用户使用以及能源浪费的问题，本公开公开了一种新风***故障判断方法、装置和告警***，应用于新风***中。 In the related art, when the fresh air system is operated in a state of lack of refrigerant, it is difficult for the user to find the fault in a short time, and the user is affected and the energy is wasted. The present disclosure discloses a method for judging the fault of the fresh air system. The device and alarm system are used in the fresh air system.

图1为本公开新风***故障判断方法的一些实施例的流程示意图。该新风***故障判断方法可以由微处理器执行，包括以下步骤：FIG. 1 is a schematic flow chart of some embodiments of a method for judging a fault of a fresh air system according to the present disclosure. The fresh air system fault determination method can be performed by a microprocessor, including the following steps:

在步骤S101，获取新风***的初始外环温度、初始内管温度和初始排气温度。In step S101, an initial outer ring temperature, an initial inner tube temperature, and an initial exhaust temperature of the fresh air system are acquired.

在该步骤中，在检测到新风***上电时，可以通过相应的温度传感器获取新风***的初始外环温度、初始内管温度和初始排气温度，其中，外环温度指室外环境温度，内管温度指新风***制冷时换热器的蒸发温度或新风***制热时换热器的冷凝温度，排气温度指压缩机排气口的温度。In this step, when it is detected that the fresh air system is powered on, the initial outer ring temperature, the initial inner tube temperature and the initial exhaust temperature of the fresh air system can be obtained by the corresponding temperature sensor, wherein the outer ring temperature refers to the outdoor ambient temperature, The tube temperature refers to the evaporation temperature of the heat exchanger when the fresh air system is cooled or the condensation temperature of the heat exchanger when the fresh air system is heated. The exhaust temperature refers to the temperature of the exhaust port of the compressor.

在步骤S102，判断初始内管温度与初始外环温度之差的绝对值是否小于等于第一目标值，若是，则执行步骤S103，否则，说明新风***处于正常模式。其中，可以通过初始内管温与初始外环温之差，预判断新风***是否缺少制冷剂，若新风***处于正常模式，即不缺少制冷剂时，初始内管温与初始外环温之差应超出预设范围内，其中，预设范围可以为由正负第一目标值形成的闭区间范围。在初始内管温与初始外环温之差位于该预设范围时，则说明新风***可能处于缺少制冷剂的故障状态，需要继续进行故障判断。其中，第一目标值可以依据用户需求进行设定。In step S102, it is determined whether the absolute value of the difference between the initial inner tube temperature and the initial outer ring temperature is less than or equal to the first target value, and if so, step S103 is performed; otherwise, the fresh air system is in the normal mode. Among them, the difference between the initial inner tube temperature and the initial outer ring temperature can be used to pre-determine whether the fresh air system lacks refrigerant. If the fresh air system is in the normal mode, that is, there is no shortage of refrigerant, the difference between the initial inner tube temperature and the initial outer ring temperature It should be outside the preset range, where the preset range can be a closed interval range formed by the positive and negative first target values. When the difference between the initial inner tube temperature and the initial outer ring temperature is within the preset range, it indicates that the fresh air system may be in a fault state lacking the refrigerant, and the fault judgment needs to be continued. The first target value can be set according to user requirements.

在步骤S103，在压缩机启动后，获取新风***的当前内管温度。At step S103, the current inner tube temperature of the fresh air system is acquired after the compressor is started.

在新风***的压缩机启动后，新风***的内管温度会发生变化。在新风***处于正常状态时，受制冷剂影响，新风***的内管温度值变化较大，在新风***处于缺少制冷剂的状态时，新风***的内管温度变化较小，因此，在压缩机启动后，需采集当前内管温度，以方便后续故障判断。After the compressor of the fresh air system is started, the temperature of the inner tube of the fresh air system changes. When the fresh air system is in a normal state, the internal pipe temperature value of the fresh air system changes greatly due to the refrigerant. When the fresh air system is in the state of lack of refrigerant, the inner pipe temperature of the fresh air system changes little, so the compressor After startup, the current inner tube temperature needs to be collected to facilitate subsequent fault diagnosis.

在步骤S104，获取与新风***的工作模式相匹配的预设判定条件。In step S104, a preset determination condition that matches the operation mode of the fresh air system is acquired.

需要说明的是，依据***的工作模式不同，当***处于制冷剂缺少状态时新风***的各项参数的表现形式也就不同，对此，在应用本公开实施例公开的故障检测方法之前，需针对于不同的模式，设置不同的判断规则。例如，当新风***工作于制冷模式时，预设条件为：初始排气温度与初始外环温度之差不小于第二目标值且初始内管温度和当前内管温度之差小于第三目标值，或初始排气温度与初始外环温度之差小于第二目标值且初始内管温度和当前内管温度之差小于第四目标值；当新风***工作于制热模式时，预设条件为：初始排气温度与初始外环温度之差不小于第二目标值且初始内管温度和当前内管温度之差的绝对值小于第五目标值，或初始排气温度与初始外环温度之差小于第二目标值且初始内管温度和当前内管温度之差的绝对值小于第六目标值。其中，第二目标值、第三目标值、第四目标值、第五目标值和第六目标值的具体值可以依据用户需求进行设定。It should be noted that, depending on the working mode of the system, when the system is in a state of lack of refrigerant, the expressions of various parameters of the fresh air system are different. For this, before applying the fault detection method disclosed in the embodiment of the present disclosure, Set different judgment rules for different modes. For example, when the fresh air system operates in the cooling mode, the preset condition is that the difference between the initial exhaust temperature and the initial outer ring temperature is not less than the second target value and the difference between the initial inner tube temperature and the current inner tube temperature is less than the third target value. , or the difference between the initial exhaust temperature and the initial outer ring temperature is less than the second target value and the difference between the initial inner tube temperature and the current inner tube temperature is less than the fourth target value; when the fresh air system operates in the heating mode, the preset condition is The difference between the initial exhaust temperature and the initial outer ring temperature is not less than the second target value and the absolute value of the difference between the initial inner tube temperature and the current inner tube temperature is less than the fifth target value, or the initial exhaust temperature and the initial outer ring temperature The difference is less than the second target value and the absolute value of the difference between the initial inner tube temperature and the current inner tube temperature is less than the sixth target value. Wherein the second target value, the third target value, the fourth target value, the fifth target value, and the sixth target value The specific value can be set according to the user's needs.

在该步骤中，在确定用于执行本次判断的预设条件后，判断初始排气温度、初始外环温度、初始内管温度和当前内管温度是否满足预设条件中的任意一项规则，如果是，则表明新风***处于制冷剂缺少故障。In this step, after determining the preset condition for performing the current determination, determining whether the initial exhaust temperature, the initial outer ring temperature, the initial inner tube temperature, and the current inner tube temperature satisfy any one of the preset conditions If it is, it indicates that the fresh air system is in the absence of refrigerant failure.

在步骤S106，确定新风***制冷剂泄漏。At step S106, it is determined that the fresh air system refrigerant leaks.

在上述实施例中，在新风***上电时，获取新风***的初始外环温度、初始内管温度和初始排气温度；在压缩机启动后，获取新风***的当前内管温度；依据新风***的工作模式选择用于进行故障判断的预设条件，若初始内管温度与初始外环温度之差的绝对值小于第一目标值，且初始排气温度与初始外环温度之差，以及初始内管温度与当前内管温度之差分别位于对应的目标范围内，说明新风***制冷剂量过少，从而使得用户能够及时发现新风***制冷剂泄漏。In the above embodiment, when the fresh air system is powered on, the initial outer ring temperature, the initial inner tube temperature, and the initial exhaust temperature of the fresh air system are acquired; after the compressor is started, the current inner tube temperature of the fresh air system is acquired; according to the fresh air system The working mode selects a preset condition for fault determination, if the absolute value of the difference between the initial inner tube temperature and the initial outer ring temperature is less than the first target value, and the difference between the initial exhaust temperature and the initial outer ring temperature, and the initial The difference between the inner tube temperature and the current inner tube temperature is respectively within the corresponding target range, indicating that the refrigerating dose of the fresh air system is too small, so that the user can find the refrigerant leakage of the fresh air system in time.

在步骤S202，判断初始内管温度与初始外环温度之差的绝对值是否小于等于第一目标值，若是，则执行步骤S203，否则，说明新风***处于正常模式。In step S202, it is determined whether the absolute value of the difference between the initial inner tube temperature and the initial outer ring temperature is less than or equal to the first target value, and if so, step S203 is performed; otherwise, the fresh air system is in the normal mode.

在步骤S203，在检测到压缩机启动时开始计时。为了保证故障判断的精准性，获取到的当前内管温度为压缩机运行设定时长后的内管温度。At step S203, timing is started upon detecting that the compressor is started. In order to ensure the accuracy of the fault diagnosis, the current inner tube temperature obtained is the inner tube temperature after the compressor is set for a long time.

在步骤S204，判断计时时长是否达到设定时长，若是，则执行步骤S205。In step S204, it is determined whether or not the timer duration has reached the set duration, and if so, step S205 is performed.

在步骤S206，获取与新风***的工作模式相匹配的预设判定条件。在新风***工作于制冷模式的情况下，预设条件为：初始排气温度与初始外环温度之差不小于第二目标值且初始内管温度与当前内管温度之差小于第三目标值，或初始排气温度与初始外环温度之差小于第二目标值且初始内管温度与当前内管温度之差小于第四目标值；在新风***工作于制热模式的情况下，预设条件为：初始排气温度与初始外环温度之差不小于第二目标值且初始内管温度与当前内管温度之差的绝对值小于第五目标值，或初始排气温度与初始外环温度之差小于第二目标值且初始内管温度与当前内管温度之差的绝对值小于第六目标值。 In step S206, a preset determination condition that matches the operation mode of the fresh air system is acquired. When the fresh air system works in the cooling mode, the preset condition is that the difference between the initial exhaust temperature and the initial outer ring temperature is not less than the second target value and the difference between the initial inner tube temperature and the current inner tube temperature is less than the third target value. , or the difference between the initial exhaust temperature and the initial outer ring temperature is less than the second target value and the difference between the initial inner tube temperature and the current inner tube temperature is less than the fourth target value; in the case where the fresh air system operates in the heating mode, the preset The condition is that the difference between the initial exhaust temperature and the initial outer ring temperature is not less than the second target value and the absolute value of the difference between the initial inner tube temperature and the current inner tube temperature is less than the fifth target value, or the initial exhaust temperature and the initial outer ring The difference between the temperatures is less than the second target value and the absolute value of the difference between the initial inner tube temperature and the current inner tube temperature is less than the sixth target value.

其中，在新风***工作时，由于压缩机的功率不同、新风***的工作模式不同、设定时长不同，所应选择的第二目标值、第三目标值、第四目标值、第五目标值和第六目标值的大小也就不同，针对于此，本公开可在执行上述方法之前，预设一映射表，该预设映射表中预存有工作模式、压缩机功率和设定时长与第二目标值、第三目标值、第四目标值、第五目标值和第六目标值之间的映射关系。Wherein, when the fresh air system is working, the second target value, the third target value, the fourth target value, and the fifth target value should be selected due to different powers of the compressor, different working modes of the fresh air system, and different setting durations. The size of the sixth target value is different from that of the sixth target value. For the purpose of the foregoing method, the disclosure may preset a mapping table, where the working mode, the compressor power, and the set duration are pre-stored.

在步骤S208，发送告警信息。其中，可以将告警信息发送至告警器，告警器用于输出表征新风***制冷剂泄露的告警信号，告警信号的类型可以依据用户需求自行设定，例如，其可以为预设语音信号或蜂鸣器告警信号等。In step S208, an alarm message is transmitted. The alarm information may be sent to the alarm device, and the alarm device is configured to output an alarm signal indicating the refrigerant leakage of the fresh air system. The type of the alarm signal may be set according to user requirements, for example, it may be a preset voice signal or a buzzer. Alarm signal, etc.

在上述实施例中，在新风***上电时，获取新风***的初始外环温度、初始内管温度和初始排气温度，在压缩机启动后，获取新风***的当前内管温度，若初始内管温度与初始外环温度之差的绝对值小于等于第一目标值，初始排气温度与初始外环温度之差，以及初始内管温度与当前内管温度之差分别位于对应的目标范围内，则说明新风***制冷剂泄漏，进而输出告警信号，从而能够及时提醒用户当前新风***是否处于缺氟故障的状态。In the above embodiment, when the fresh air system is powered on, the initial outer ring temperature, the initial inner tube temperature, and the initial exhaust temperature of the fresh air system are acquired, and after the compressor is started, the current inner tube temperature of the fresh air system is acquired, if the initial inner The absolute value of the difference between the tube temperature and the initial outer ring temperature is less than or equal to the first target value, the difference between the initial exhaust temperature and the initial outer ring temperature, and the difference between the initial inner tube temperature and the current inner tube temperature are respectively within the corresponding target ranges. , indicating that the fresh air system refrigerant leaks, and then outputs an alarm signal, so as to promptly remind the user whether the current fresh air system is in a state of lack of fluorine fault.

下面以处于制冷模式的新风***进行故障判断为例进行举例说明，其中，可以通过映射表查找到第一目标值设置为5℃、第二目标值设置为10℃、第三目标值设置为3℃、第四目标值设置为2℃、设定时长设置为6分钟。The following is an example of fault diagnosis by using a fresh air system in a cooling mode.

The communication address of the user terminal may be a communication address reserved by the user. Considering that the service life of the fresh air system is long, the system may change the contact mode of the user or the user, and the fresh air system may also be automatically used. The device search is performed within a preset range of the center, and when the user terminal is searched, the communication address of the communication device is acquired.

在步骤S302，依据通信地址向用户终端输出维修服务发送请求，以便用户终端向预设网络服务器发送维修服务请求。该维修服务发送请求可以包括新风***的型号标识信息。In step S302, a service delivery request is output to the user terminal according to the communication address, so that the user terminal sends a service request to the preset network server. The service delivery request may include model identification information for the fresh air system.

在新风***因制冷剂缺少而出现故障时，可以向用户终端输出维修服务发送请求，以请示用户是否需要对新风***进行维修。When the fresh air system fails due to lack of refrigerant, a service service transmission request may be output to the user terminal to indicate whether the user needs to perform maintenance on the fresh air system.

其中，用户响应维修服务发送请求指的是，在用户终端获取到维修服务发送请求时，可以将该请求通过预设窗口展示给用户，在用户终端通过该预设窗口获取到用户键入的确认指令时，即表明用户响应了维修服务发送请求。此时，用户终端生成维修服务请求并将该维修服务请求发送至预设网络服务器，其中，预设网络服务器为与新风***的厂商相匹配的网络服务器，例如，在新风***的生产厂商为格力时，将该维修服务请求发送与格力公司相匹配的网络服务器中。The user response service request sending request refers to that when the user terminal obtains the service sending request, the request may be displayed to the user through a preset window, and the user terminal obtains the confirmation command typed by the user through the preset window. When the user responds to the repair service to send a request. At this time, the user terminal generates a service request and sends the service request to the preset network server, wherein the preset network server is a network server matching the manufacturer of the fresh air system, for example, the manufacturer of the fresh air system is Gree.

在上述实施例中，在新风***出现故障时，可以根据与新风***相对应的用户终端的通信地址，向用户终端输出维修服务发送请求，以便用户终端向预设网络服务器发送维修服务请求，从而能够及时通知维修人员对新风***进行维修。In the above embodiment, when the fresh air system fails, the repair service sending request may be output to the user terminal according to the communication address of the user terminal corresponding to the fresh air system, so that the user terminal sends a repair service request to the preset network server, thereby The maintenance personnel can be notified in time to repair the fresh air system.

图4为本公开新风***故障判断装置的一些实施例的结构示意图。该新风***故障判断装置可以为微处理器，包括数据采集模块110、第一判断模块120和第二判断模块130。 FIG. 4 is a schematic structural diagram of some embodiments of a fresh air system fault judging device according to the present disclosure. The fresh air system fault judging device may be a microprocessor, and includes a data collecting module 110, a first judging module 120, and a second judging module 130.

其中，数据采集模块110用于在新风***上电时，获取新风***的初始外环温度、初始内管温度和初始排气温度，以及在压缩机启动后，获取新风***的当前内管温度。其中，在新风***的压缩机启动后，新风***的内管温度会发生变化。在新风***处于正常状态时，受制冷剂影响，新风***的内管温度值变化较大，在新风***处于缺少制冷剂的状态时，新风***的内管温度变化较小，因此，在压缩机启动后，需采集当前内管温度，以方便后续故障判断。The data acquisition module 110 is configured to acquire an initial outer ring temperature, an initial inner tube temperature, and an initial exhaust temperature of the fresh air system when the fresh air system is powered on, and acquire a current inner tube temperature of the fresh air system after the compressor is started. Among them, the inner tube temperature of the fresh air system changes after the compressor of the fresh air system is started. When the fresh air system is in a normal state, the internal pipe temperature value of the fresh air system changes greatly due to the refrigerant. When the fresh air system is in the state of lack of refrigerant, the inner pipe temperature of the fresh air system changes little, so the compressor After startup, the current inner tube temperature needs to be collected to facilitate subsequent fault diagnosis.

第一判断模块120用于判断初始内管温度与初始外环温度之差的绝对值是否小于等于第一目标值，若初始内管温度与初始外环温度之差的绝对值小于等于第一目标值，则向第二判断模块120块输出触发信号。其中，第一目标值可以依据用户需求进行设定。The first determining module 120 is configured to determine whether the absolute value of the difference between the initial inner tube temperature and the initial outer ring temperature is less than or equal to the first target value, and if the absolute value of the difference between the initial inner tube temperature and the initial outer ring temperature is less than or equal to the first target The value outputs a trigger signal to the second determination module 120 block. The first target value can be set according to user requirements.

其中，新风***处于不同的工作模式时，在制冷剂缺少的状态下，新风***的各项参数的表现形式不同，因此，新风***在不同的工作模式下，初始排气温度与初始外环温度之差，以及初始内管温度与当前内管温度之差对应的目标范围也不同。例如，在新风***工作于制冷模式的情况下，若初始排气温度与初始外环温度之差不小于第二目标值且初始内管温度与当前内管温度之差小于第三目标值，或初始排气温度与初始外环温度之差小于第二目标值且初始内管温度与当前内管温度之差小于第四目标值，则确定新风***制冷剂泄漏；在新风***工作于制热模式的情况下，若初始排气温度与初始外环温度之差不小于第二目标值且初始内管温度与当前内管温度之差的绝对值小于第五目标值，或初始排气温度与初始外环温度之差小于第二目标值且初始内管温度与当前内管温度之差的绝对值小于第六目标值，则确定新风***制冷剂泄漏。其中，第二目标值、第三目标值、第四目标值、第五目标值和第六目标值的具体值可以依据用户需求进行设定。Among them, when the fresh air system is in different working modes, the parameters of the fresh air system are different in the state of lack of refrigerant. Therefore, the initial exhaust temperature and the initial outer ring temperature of the fresh air system in different working modes The difference, and the target range corresponding to the difference between the initial inner tube temperature and the current inner tube temperature are also different. For example, if the fresh air system is operating in the cooling mode, if the difference between the initial exhaust temperature and the initial outer ring temperature is not less than the second target value and the difference between the initial inner tube temperature and the current inner tube temperature is less than the third target value, or The difference between the initial exhaust temperature and the initial outer ring temperature is less than the second target value and the difference between the initial inner tube temperature and the current inner tube temperature is less than the fourth target value, thereby determining the fresh air system refrigerant leakage; operating in the fresh air system in the heating mode If the difference between the initial exhaust temperature and the initial outer ring temperature is not less than the second target value and the absolute value of the difference between the initial inner tube temperature and the current inner tube temperature is less than the fifth target value, or the initial exhaust temperature and initial If the difference between the outer ring temperatures is less than the second target value and the absolute value of the difference between the initial inner tube temperature and the current inner tube temperature is less than the sixth target value, the fresh air system refrigerant leak is determined. The specific values of the second target value, the third target value, the fourth target value, the fifth target value, and the sixth target value may be set according to user requirements.

在上述实施例中，在新风***上电时，获取新风***的初始外环温度、初始内管温度和初始排气温度；在压缩机启动后，获取新风***的当前内管温度；依据新风***的工作模式选择用于进行故障判断的预设条件，若初始内管温度与初始外环温度之差的绝对值小于第一目标值，且初始排气温度与初始外环温度之差，以及初始内管温度与当前内管温度之差分别位于对应的目标范围内，则说明新风***制冷剂量过少，从而使得用户能够及时发现新风***制冷剂泄漏，降低能源浪费，提升用户体验。In the above embodiment, when the fresh air system is powered on, the initial outer ring temperature, the initial inner tube temperature, and the initial exhaust temperature of the fresh air system are acquired; after the compressor is started, the current inner tube temperature of the fresh air system is acquired; according to the fresh air system The working mode selects a preset condition for fault determination, if the absolute value of the difference between the initial inner tube temperature and the initial outer ring temperature is less than the first target value, and the difference between the initial exhaust temperature and the initial outer ring temperature, and the initial The difference between the inner tube temperature and the current inner tube temperature is within the corresponding target range, indicating that the fresh air system has too little refrigerant.
