In the detection method provided by the technical scheme of the invention, at least one of the outdoor unit systems to be detected is started, whether the working condition parameters of the air conditioning system meet the preset conditions or not is judged, if the working condition parameters of the air conditioning system meet the preset conditions, the indoor unit system is matched with the started outdoor unit system, in other words, the signal lines and the refrigerant pipelines between the indoor unit system and the started outdoor unit system are connected consistently.
By the detection method, whether the connection between the signal line of the indoor unit system and the outdoor unit system and the refrigerant pipeline is constant or not can be detected, the detection accuracy is high, and the workload of manual investigation can be greatly reduced.
In addition, the detection method provided by the technical scheme of the invention also has the following additional technical characteristics:
in one embodiment, the controlling at least one of the outdoor unit systems to be detected by the processor to start up includes: and the processor controls one of the outdoor unit systems to be detected to start up and operates a refrigeration mode or a heating mode.
The method comprises the steps of controlling one outdoor unit system to be detected to be started, operating a refrigeration mode or a heating mode, and when the outdoor unit system is started to operate the refrigeration mode or the heating mode, causing working condition parameters of an air conditioning system to change, so that whether an indoor unit system is matched with the started outdoor unit system can be determined according to whether the working condition parameters meet preset conditions, namely, whether the signal lines of the outdoor unit system and the indoor unit system are connected with a refrigerant pipeline is detected.
In one embodiment, the controlling at least one of the outdoor unit systems to be detected by the processor to start up includes: and the processor controls the start-up of two outdoor unit systems to be detected and respectively operates the refrigeration mode and the heating mode.
The working condition parameters of the air conditioning system in the cooling mode and the heating mode are different. Therefore, two outdoor unit systems to be detected are controlled to be started, the systems where the two outdoor unit systems are located are distinguished by respectively operating the refrigeration mode and the heating mode, so that the two outdoor unit systems are controlled to be started, and whether the outdoor unit systems are matched with the indoor unit systems or not can be detected through working condition parameters of the air conditioning system.
And the two outdoor machine systems are started simultaneously, so that the detection efficiency for detecting whether the indoor machine systems and the outdoor machine systems are matched can be improved, and the detection time is shortened.
In one embodiment, the operating condition parameters of the air conditioning system include the operating condition parameters of the indoor unit to be detected, and the operating condition parameters of the air conditioning system satisfy preset conditions, which specifically include: and the working condition parameters of the indoor unit to be detected meet the preset conditions.
When the signal lines of the outdoor unit system and the indoor unit system are connected with the refrigerant pipeline in a consistent manner, the outdoor unit system is started to operate in a heating or cooling mode, and the indoor unit system and the outdoor unit system which are connected with the outdoor unit system through the signal lines and the refrigerant pipeline form a refrigerant flow path to operate in the heating or cooling mode. Therefore, the working condition parameters of the indoor unit connected with the outdoor unit system can be changed, so that whether the indoor unit system is matched with the outdoor unit system in starting operation or not can be judged by detecting whether the working condition parameters of the indoor unit system before and after starting the machine meet the preset conditions or not.
In one embodiment, the operating condition parameters include a temperature of an indoor heat exchanger, and the operating condition parameters of the indoor unit to be detected satisfy the preset conditions, which specifically include: operating a refrigeration mode, wherein the difference value of the temperatures of the indoor heat exchangers to be detected before and after starting is greater than a first preset difference value; and operating the heating mode, wherein the difference value of the temperatures of the indoor heat exchangers to be detected before and after starting is smaller than a second preset difference value.
When the signal lines of the outdoor unit system and the indoor unit system are connected with the refrigerant pipeline in a consistent manner, the outdoor unit system is started to operate in a refrigeration mode, the indoor unit system connected with the outdoor unit system and the outdoor unit system operate together to refrigerate, the refrigerant is evaporated in the indoor heat exchanger, and the temperature of the indoor heat exchanger is reduced. Therefore, the temperature of the indoor heat exchanger before starting is higher than that of the indoor heat exchanger after starting, the difference value of the temperatures of the indoor heat exchanger before and after starting is higher than a first preset difference value, the indoor unit system operates in a refrigeration mode together with the outdoor unit system, and the indoor unit system is matched with the outdoor unit system. And if the difference value of the temperatures of the indoor heat exchangers before and after starting up is smaller than or equal to a first preset difference value, the indoor unit system is not matched with the outdoor unit system.
When the signal lines of the outdoor unit system and the indoor unit system are connected with the refrigerant pipeline in a consistent manner, the outdoor unit system is started to operate in a heating mode, the indoor unit system connected with the outdoor unit system and the outdoor unit system operate together to heat, the refrigerant is condensed in the indoor heat exchanger, and the temperature of the indoor heat exchanger is increased. Therefore, the temperature of the indoor heat exchanger before starting is higher than that of the indoor heat exchanger after starting, and the difference value between the temperatures of the indoor heat exchanger before and after starting is smaller than a second preset difference value, so that the indoor unit system operates in a heating mode together with the outdoor unit system, and the indoor unit system is matched with the outdoor unit system. And if the difference value of the temperatures of the indoor heat exchangers before and after starting is larger than a second preset difference value, the indoor unit system is not matched with the outdoor unit system.
The temperature of the indoor heat exchanger can be the temperature of the inlet, the temperature of the outlet or the temperature of the middle part of the indoor heat exchanger, and can also be the temperature of other positions of the indoor heat exchanger besides the inlet, the outlet and the middle part.
The working condition parameter can be temperature and pressure of refrigerant in the indoor heat exchanger.
In one embodiment, the determining that the indoor unit system is matched with the opened outdoor unit system further includes: and moving the matched indoor unit systems out of the range of the indoor unit systems to be detected, moving the matched outdoor unit systems out of the range of the outdoor unit systems to be detected, and returning to the processor to control at least one starting machine in the outdoor unit systems to be detected to operate until the number of the outdoor unit systems to be detected is zero.
And after the outdoor unit system i is determined to be matched with the indoor unit system i, the indoor unit system i and the outdoor unit system i are respectively moved out of the indoor unit system to be detected and the outdoor unit system to be detected. Therefore, when the step of controlling the starting operation of at least one outdoor unit system to be detected by the processor is returned, the indoor unit system i is not in the range of the indoor unit system to be detected, and the outdoor unit system i is not in the range of the outdoor unit system to be detected, so that repeated detection is avoided.
In one embodiment, the detection method comprises the following steps: judging that the working condition parameters of the air conditioning system do not meet preset conditions, determining that the indoor unit system is not matched with the started outdoor unit system, moving the unmatched indoor unit system out of the range of the indoor unit system to be detected, moving the unmatched outdoor unit system out of the range of the outdoor unit system to be detected, and returning to the processor to control at least one starting machine in the outdoor unit system to be detected to operate until the number of the outdoor unit systems to be detected is zero.

In order to prevent the unmatched indoor unit system j and outdoor unit system j from being repeatedly detected when the return processor controls the starting operation of at least one of the outdoor unit systems to be detected, the unmatched indoor unit system j is moved out of the indoor unit system to be detected, and the unmatched outdoor unit system j is moved out of the outdoor unit system to be detected.

In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced otherwise than as specifically described herein, and thus the scope of the present invention is not limited by the specific embodiments disclosed below.
A detection method, a detection apparatus, an air conditioning system, and a computer-readable storage medium according to some embodiments of the present invention are described below with reference to fig. 1 to 8 of the accompanying drawings.
As shown in fig. 1, a method for detecting matching between an indoor unit system and an outdoor unit system of an air conditioning system according to some embodiments of the present invention includes:
step S102, a processor controls at least one starting up operation in an outdoor unit system to be detected;
and step S104, judging that the working condition parameters of the air conditioning system meet preset conditions, and determining that the indoor unit system is matched with the opened outdoor unit system.
The processor can be any one of an indoor unit system, an outdoor unit system and a remote monitoring device, and the indoor unit system, the outdoor unit system or the remote monitoring device can send a positioning instruction to further realize positioning operation. The remote monitoring device can be a center console, and also can be a mobile terminal (which can be internally provided with an APP for monitoring the devices) such as a mobile phone and a computer, and a cloud central control module. The remote monitoring device is connected with the multi-connected air conditioning system through a network, can monitor one or more sets of multi-connected air conditioning systems, and can also display the position of any indoor unit system or outdoor unit system.
In the detection method provided in the above embodiment of the present invention, at least one of the outdoor unit systems to be detected is turned on, and whether the operating condition parameter of the air conditioning system meets the preset condition is determined, and if the operating condition parameter of the air conditioning system meets the preset condition, it is determined that the indoor unit system is matched with the turned-on outdoor unit system, in other words, the signal line 30 between the indoor unit system 20 and the turned-on outdoor unit system 10 is connected to the refrigerant pipeline in a consistent manner.
As shown IN fig. 6, the outdoor unit system OUT1 and the indoor unit system IN1 are connected by refrigerant pipes and by signal lines, so that the refrigerant pipes and the signal lines are connected IN a consistent manner, and the outdoor unit system OUT1 is matched with the indoor unit system IN 1. The outdoor unit system OUT2 and the indoor unit system IN2 are connected by refrigerant pipes and by signal lines, so that the refrigerant pipes and the signal lines are connected IN a consistent manner, and the outdoor unit system OUT2 is matched with the indoor unit system IN 2. The outdoor unit system OUT3 and the indoor unit system IN3 are connected by refrigerant pipes and by signal lines, so that the refrigerant pipes and the signal lines are connected IN a consistent manner, and the outdoor unit system OUT3 is matched with the indoor unit system IN 3.
In the system with abnormality, the signal line may be connected to another refrigerant system, which results in abnormal operation of the system, and the schematic diagram 7 shows the wrong connection. The outdoor unit system OUT1 and the indoor unit system IN1 are connected by refrigerant pipes, and the outdoor unit system OUT1 and the indoor unit system IN3 are connected by signal lines, so that the outdoor unit system OUT1 is not matched with the indoor unit system IN 1. The outdoor unit system OUT2 and the indoor unit system IN2 are connected by a refrigerant pipe and by a signal line, and the outdoor unit system OUT2 and the indoor unit system IN1 are connected by a signal line, so that the outdoor unit system OUT2 is not matched with the indoor unit system IN 2. The outdoor unit system OUT3 and the indoor unit system IN3 are connected by refrigerant pipes, and the outdoor unit system OUT3 and the indoor unit system IN2 are connected by signal lines, so that the outdoor unit system OUT3 is not matched with the indoor unit system IN 3.
Furthermore, the indoor unit system comprises at least one indoor unit, and the outdoor unit system comprises at least one outdoor unit.
By the detection method, whether the connection between the signal line of the indoor unit system and the outdoor unit system and the refrigerant pipeline is constant or not can be detected, the detection accuracy is high, and the workload of manual investigation can be greatly reduced.
Further, the method is suitable for the air conditioning system with the GPS positioning function and the 2G/3G/4G communication function. The indoor unit system and the outdoor unit system can establish communication connection in a wired connection (such as connection through 485 communication lines) and/or wireless connection (such as WIFI connection or other modes).
The first embodiment is as follows:
as shown in fig. 2, the detection method includes:
step S202, a processor controls two sets of outdoor units to be detected to be started, and respectively operates a refrigeration mode and a heating mode;
step S204, judging that the working condition parameters of the air conditioning system meet preset conditions, determining that the indoor unit system is matched with the opened outdoor unit system, moving the matched indoor unit system out of the range of the indoor unit system to be detected, moving the matched outdoor unit system out of the range of the outdoor unit system to be detected, and returning to the processor to control at least one starting-up operation in the outdoor unit system to be detected until the number of the outdoor unit systems to be detected is zero;
step S206, judging that the working condition parameters of the air conditioning system do not meet the preset conditions, determining that the indoor unit system is not matched with the opened outdoor unit system, moving the unmatched indoor unit system out of the range of the indoor unit system to be detected, moving the unmatched outdoor unit system out of the range of the outdoor unit system to be detected, and returning to the processor to control at least one of the outdoor unit systems to be detected to start up and operate until the number of the outdoor unit systems to be detected is zero.
In step S202, the operating condition parameters of the air conditioning system in the cooling mode and the heating mode are different. Therefore, two outdoor unit systems to be detected are controlled to be started, the systems where the two outdoor unit systems are located are distinguished by respectively operating the refrigeration mode and the heating mode, so that the two outdoor unit systems are controlled to be started, and whether the outdoor unit systems are matched with the indoor unit systems or not can be detected through working condition parameters of the air conditioning system.
And the two outdoor machine systems are started simultaneously, so that the detection efficiency for detecting whether the indoor machine systems and the outdoor machine systems are matched can be improved, and the detection time is shortened.
Further, the operating mode parameter of air conditioning system includes the operating mode parameter of the indoor set that awaits measuring, and air conditioning system's operating mode parameter satisfies the preset condition, specifically includes: and the working condition parameters of the indoor unit to be detected meet the preset conditions.
When the signal lines of the outdoor unit system and the indoor unit system are connected with the refrigerant pipeline in a consistent manner, the outdoor unit system is started to operate in a heating or cooling mode, and the indoor unit system and the outdoor unit system which are connected with the outdoor unit system through the signal lines and the refrigerant pipeline form a refrigerant flow path to operate in the heating or cooling mode. Therefore, the working condition parameters of the indoor unit connected with the outdoor unit system can be changed, so that whether the indoor unit system is matched with the outdoor unit system in starting operation or not can be judged by detecting whether the working condition parameters of the indoor unit system before and after starting the machine meet the preset conditions or not.
Further, the operating condition parameter of the indoor unit is an operating condition parameter of the indoor heat exchanger, such as a temperature operating condition parameter of the indoor heat exchanger.
Further, the operating mode parameter of indoor heat exchanger is the temperature of indoor set, and air conditioning system's operating mode parameter satisfies the preset condition, specifically includes: operating a refrigeration mode, wherein the difference value of the temperatures of the indoor heat exchangers to be detected before and after starting is greater than a first preset difference value; and operating the heating mode, wherein the difference value of the temperatures of the indoor heat exchangers to be detected before and after starting is smaller than a second preset difference value. The temperature of the indoor heat exchanger can be an inlet temperature, a middle temperature, an outlet temperature of the indoor heat exchanger or a temperature at other positions of the indoor heat exchanger.
Further, the operation refrigeration mode, operating condition parameter include indoor heat exchanger's middle part temperature, for example indoor heat exchanger's middle part average temperature, and the operating condition parameter of the indoor set that awaits measuring satisfies the preset condition, specifically includes: the difference value of the temperatures of the middle parts of the indoor heat exchangers to be detected before and after starting is larger than a first preset difference value.
The operation mode of heating, operating condition parameter include indoor heat exchanger's outlet temperature, for example indoor heat exchanger's outlet average temperature, and the operating condition parameter of the indoor set that awaits measuring satisfies the preset condition, specifically includes: and the difference value of the outlet temperatures of the indoor heat exchangers to be detected before and after starting is smaller than a second preset difference value.
When the signal lines of the outdoor unit system and the indoor unit system are connected with the refrigerant pipeline in a consistent manner, the outdoor unit system is started to operate in a refrigeration mode, the indoor unit system connected with the outdoor unit system and the outdoor unit system operate together to refrigerate, the refrigerant is evaporated in the indoor heat exchanger, and the temperature of the middle part of the indoor heat exchanger is reduced. Therefore, the temperature of the middle part of the indoor heat exchanger before starting is higher than that of the middle part of the indoor heat exchanger after starting, the difference value of the temperatures of the middle parts of the indoor heat exchanger before and after starting is higher than a first preset difference value, the indoor unit system operates in a refrigeration mode together with the outdoor unit system, and the indoor unit system is matched with the outdoor unit system. And if the difference value of the temperatures of the middle parts of the indoor heat exchangers before and after starting is smaller than or equal to a first preset difference value, the indoor unit system is not matched with the outdoor unit system.
The first predetermined difference is greater than 0 deg.c, for example the first predetermined difference may be 3 deg.c.
For the difference of the middle temperature of the indoor heat exchanger before and after starting up to be more stable and to prevent misjudgment, the middle temperature of the indoor heat exchanger is acquired after the first preset time of the starting up operation. The first preset time period is 2min to 10min, for example, the first preset time period may be 3 min.
When the signal lines of the outdoor unit system and the indoor unit system are connected with the refrigerant pipeline in a consistent manner, the outdoor unit system is started to operate in a heating mode, the indoor unit system connected with the outdoor unit system and the outdoor unit system operate together to heat, the refrigerant is condensed in the indoor heat exchanger, and the temperature of the outlet of the indoor heat exchanger is increased. Therefore, the temperature of the outlet of the indoor heat exchanger before starting is higher than that of the outlet of the indoor heat exchanger after starting, and the difference value of the outlet temperatures of the indoor heat exchangers before and after starting is smaller than a second preset difference value, so that the indoor unit system operates in a heating mode together with the outdoor unit system, and the indoor unit system is matched with the outdoor unit system. And if the difference value of the outlet temperatures of the indoor heat exchangers before and after starting is larger than a second preset difference value, the indoor unit system is not matched with the outdoor unit system.
The second predetermined difference is less than 0 deg.C, for example the second predetermined difference may be-3 deg.C.
For the difference of the outlet temperatures of the indoor heat exchangers before and after starting up to be more stable and to prevent misjudgment, the outlet temperature of the indoor heat exchanger is acquired after the second preset time of the starting up operation. The second preset time period is 2min-10min, for example, the second preset time period may be 3 min.
As shown in fig. 8, an indoor heat exchanger is taken as an example of an evaporator 70, an outlet of the evaporator is connected to a gas-side shutoff valve 40, an inlet thereof is connected to a liquid-side shutoff valve 50, and a throttle device 60 (e.g., an electronic expansion valve) is connected in series between the liquid-side shutoff valve 50 and the inlet. The outlet temperature of the evaporator 70 is the temperature at a, for example, a temperature sensor may be provided at a to obtain the temperature at a, and the middle temperature of the evaporator is the temperature at B, for example, a temperature sensor may be provided at B to obtain the temperature at B.
In step S204, after it is determined that the outdoor unit system i matches the indoor unit system i, the indoor unit system i and the outdoor unit system i are respectively removed from the indoor unit system to be detected and the outdoor unit system to be detected. Therefore, when the step of controlling at least one starting up operation in the outdoor unit system to be detected by the processor is returned, the indoor unit system i is not in the range of the indoor unit system to be detected, and the outdoor unit system i is not in the range of the outdoor unit system to be detected, so that repeated detection is avoided.
In step S206, when it is determined that the operating condition parameter of the air conditioning system does not satisfy the preset condition, it indicates that the indoor unit system j is not matched with the opened outdoor unit system j, and indicates that the connection between the signal line and the refrigerant pipeline is inconsistent. In order to prevent the unmatched indoor unit system j and outdoor unit system j from being repeatedly detected when the return processor controls at least one starting up operation in the outdoor unit system to be detected, the unmatched indoor unit system j is moved out of the indoor unit system to be detected, and the unmatched outdoor unit system j is moved out of the outdoor unit system to be detected.
