Fig. 1 is a flow chart schematically illustrating a method for detecting a refrigerant quantity of an air conditioner according to an embodiment of the present invention. Referring to fig. 1, the method for detecting the amount of refrigerant in an air conditioner according to the embodiment of the present invention includes steps S11 to S13, as follows:
and S11, receiving a refrigerant detection signal triggered by the client, wherein the refrigerant detection signal carries the real-time working state parameter of the air conditioner to be detected.
Specifically, the operating state parameters of the air conditioner include: the set state parameters of the air conditioner, the equipment operation parameters, the equipment state parameters and the environmental parameters of the environment where the air conditioner is located.
In this embodiment, the set state parameter includes at least one of an operation mode, a set temperature, a wind level, and a wind sweeping direction; the equipment operation parameters comprise at least one of compressor frequency, inner fan rotating speed, outdoor machine rotating speed and electronic expansion valve opening degree; the equipment state parameters comprise at least one of evaporator tube temperature, condenser tube temperature, heat exchanger inlet temperature, heat exchanger outlet temperature, exhaust temperature, suction temperature, system high pressure, system low pressure and air outlet temperature; the environmental parameter includes at least one of an indoor ambient temperature, an indoor relative humidity, an outdoor ambient temperature, and an outdoor relative humidity.
And S12, searching a preset standard database to obtain the refrigerant quantity matched with the real-time working state parameter, wherein the standard database comprises the corresponding relation between the working state parameter of the air conditioner and the refrigerant quantity.
In this embodiment, the preset standard database includes a corresponding relationship between the air conditioner and the operating state parameters of the air conditioner when the air conditioner is in various refrigerant quantity states. The working state parameters of the air conditioner refer to a set of parameters including specific environmental parameters under the current operating condition, set state parameters of the air conditioner, equipment operating parameters of the air conditioner and equipment state parameters of the air conditioner.
Specifically, the real-time working state parameters of the air conditioner to be detected carried in the refrigerant detection signal are matched with the working state parameters which are prestored in the standard database and have corresponding relations with the refrigerant quantity, and after the prestored working state parameters which are consistent with the specific parameters are matched, the refrigerant quantity which has corresponding relations with the specific parameters can be determined to be the actual refrigerant quantity of the air conditioner to be detected.
And S13, sending the obtained refrigerant quantity to the client to prompt a user to add refrigerant to the air conditioner to be detected according to the refrigerant quantity.
Specifically, the refrigerant quantity detection result is sent to the user client, and a recommended scheme for adding the refrigerant suitable for the current refrigerant quantity can also be sent. The client may be a client that triggers the refrigerant detection signal, or a client that is specified by another user or has a binding relationship established.
According to the refrigerant quantity detection method of the air conditioner, after the refrigerant detection message which is triggered by the client and carries the real-time working state parameters of the air conditioner to be detected is received, the refrigerant quantity matched with the real-time working state parameters is obtained by searching the preset standard database, and the refrigerant quantity is sent to the client to prompt a user to add the refrigerant to the air conditioner to be detected according to the actual refrigerant quantity, so that the actual refrigerant quantity of the air conditioner can be accurately detected, effective guidance is provided for maintenance personnel when the refrigerant of the air conditioner is insufficient, the working difficulty of the maintenance personnel is reduced, and the accuracy of the refrigerant adding quantity is improved.
In an embodiment of the present invention, the step S12 of searching a preset standard database to obtain the refrigerant quantity matched with the real-time operating state parameter specifically includes the following steps S121 to S123 not shown in the drawings:
and S121, comparing at least one of the set state parameters, the equipment operation parameters, the equipment state parameters and the environment parameters of the air conditioner serving as comparison parameters with the working state parameters including the corresponding parameters in the standard database to obtain a data comparison result of each parameter.
For example, if the refrigerant detection signal carries two set state parameters of the air conditioner to be detected: setting the temperature to be 16 ℃ and the wind gear to be 2; and two plant operating parameters: the frequency of the compressor is 60Hz, and the opening of the electronic expansion valve is 300 steps; and three device status parameters: the tube temperature of the evaporator is 12 ℃, the tube temperature of the condenser is 50 ℃, and the exhaust temperature is 80 ℃; and two environmental parameters under current operating conditions: the indoor ambient temperature is 30 ℃ and the outdoor ambient temperature is 35 ℃. In this embodiment, the above listed parameters are used as comparison parameters to be compared with the operating state parameters in the standard database.
Specifically, the enumerated parameter values are respectively compared with the working state parameter sets which are pre-stored in the standard database and comprise the corresponding parameters. For example, assume that two sets of operating condition parameters are pre-stored in the standard database, where:
the first group includes: two setting state parameters: setting the temperature to be 18 ℃ and the wind gear to be 2; and two plant operating parameters: the frequency of the compressor is 50Hz, and the opening of the electronic expansion valve is 200 steps; and three device status parameters: the tube temperature of the evaporator is 13 ℃, the tube temperature of the condenser is 60 ℃, and the exhaust temperature is 70 ℃; and two environmental parameters under current operating conditions: the indoor environment temperature is 27 ℃, and the outdoor environment temperature is 32 ℃;
the second group includes: two setting state parameters: setting the temperature to be 24 ℃ and the wind gear to be 1 gear; and two plant operating parameters: the frequency of the compressor is 30Hz, and the opening of the electronic expansion valve is 100 steps; and three device status parameters: the tube temperature of the evaporator is 16 ℃, the tube temperature of the condenser is 35 ℃, and the exhaust temperature is 65 ℃; and two environmental parameters under current operating conditions: the indoor ambient temperature is 23 ℃ and the outdoor ambient temperature is 28 ℃.
Further, the numerical values of all parameters in the real-time working state parameters of the air conditioner to be detected are compared with the numerical values of all parameters corresponding to each group of working state parameters prestored in the standard database, and the data comparison results of all parameters are obtained. In this embodiment, the absolute value of the difference between the two sets of data to be compared is, for example, compared with the first set, the comparison result of the parameter [ set temperature ] is 2, the comparison result of the parameter [ exhaust temperature ] is 10, and the comparison results of the other parameters are obtained as the same as the data of the corresponding parameter in the two sets of operating state parameters.
And S122, judging whether the data comparison results corresponding to the parameters respectively fall into the preset threshold interval corresponding to the current parameter.
And S123, if so, taking the refrigerant quantity corresponding to the working state parameters of each corresponding parameter in the standard database as the refrigerant quantity matched with the real-time working state parameters.
Specifically, the obtained data comparison result of each corresponding parameter is compared with the preset threshold interval corresponding to the current parameter respectively. For example, the preset threshold interval corresponding to the parameter [ set temperature ] is (0,3), the preset threshold interval corresponding to the parameter [ exhaust temperature ] is (0,5), and the comparison result between the two sets of operating state parameters and the corresponding preset threshold interval are respectively compared in the same way for other parameters. Further, if the comparison results of the parameters between the first set of operating state parameters and the first set of operating state parameters all fall into the corresponding preset threshold intervals, and the comparison results of the parameters between the second set of operating state parameters do not fall into the corresponding preset threshold intervals or the number of the parameters falling into the corresponding preset threshold intervals is small, it is indicated that the real-time operating state parameters of the air conditioner to be detected are matched with the first set of pre-stored operating state parameters in a consistent manner.
Optimally, the prestored working state parameters which are the same as all corresponding parameter values in the real-time working state parameters are judged to be matched consistently. Compared with the real-time working state parameters, the working state parameters with the most same numerical values in the corresponding parameters, or the most comparison results of the corresponding parameters falling into the preset threshold interval, or the comparison results of the corresponding parameters falling into the preset threshold interval, and the group of working state parameters with the least numerical values difference are judged to be matched consistently, and can be specifically set according to actual needs without limitation.
And further, determining the refrigerant quantity corresponding to the working state parameter which is judged to be matched and consistent in the standard database as the actual refrigerant quantity of the air conditioner to be detected.
It is understood that the environmental parameters, the set state parameters of the air conditioner, and the equipment operating parameters collectively affect the equipment state parameters of the air conditioner. When the air conditioner runs under different refrigerant quantity states, the equipment state parameters of the air conditioner are different under the same environment parameters, the set state parameters of the air conditioner and the equipment running parameters. Therefore, the refrigerant quantity corresponding to the same or the closest working state parameter can be used as the actual refrigerant quantity of the air conditioner by comparing with the real-time working state parameter. In particular, the equipment state parameter of the air conditioner is a necessary comparison parameter.
In an embodiment of the present invention, the refrigerant detection signal further carries model identification information of an air conditioner to be detected, and correspondingly, in step S12, the preset standard database is searched to obtain the refrigerant quantity matched with the real-time operating state parameter, which further includes the following steps:
screening out a target data set corresponding to the air conditioner to be detected from a preset standard database according to the model identification information;
and searching the target data set to obtain the refrigerant quantity matched with the real-time working state parameters.
Specifically, because the performance and the operation state of the air conditioners of different series or different models are different in the same refrigerant quantity state, target data sets respectively corresponding to the air conditioners of different series or different models are prestored in a preset standard database, and the target data sets include the corresponding relation between the air conditioners of the current series or current model and the working state parameters in different refrigerant quantity states.
In this embodiment, the refrigerant detection signal carries model identification information of the air conditioner to be detected, and through the model identification information, target data corresponding to the model identification in the standard database can be searched in a centralized manner, and finally, the amount of refrigerant matched with the air conditioner to be detected is determined. The specific search method is described in the foregoing embodiments, and will not be explained herein.
In a specific embodiment, before refrigerant detection is triggered, the model of the air conditioner can be identified by scanning a two-dimensional code or a bar code or other identification information of a body of the air conditioner to be detected or inputting the model or the bar code of the air conditioner to be detected so as to lock a target data set, and the refrigerant quantity matched with the air conditioner to be detected is searched and determined.

Further, those skilled in the art will appreciate that the embodiments described in the specification are presently preferred and that no particular act is required to implement the invention.
