and determining that a refrigerant detection instruction is received, and executing the step of acquiring the operating parameters of the air conditioner corresponding to the environmental parameters of the environment where the air conditioner is located.
Referring to fig. 2, in an embodiment of the refrigerant detection method of the present invention, the refrigerant detection method includes the following steps:
step S10, obtaining the operation parameters of the air conditioner corresponding to the environment parameters of the environment where the air conditioner is located;
step S20, controlling the air conditioner to operate according to the operation parameters;
step S30, determining that the operation time of the air conditioner according to the operation parameters is longer than or equal to a preset time, and acquiring condensation parameters of the air conditioner, wherein the condensation parameters comprise at least one of condensation temperature and condensation pressure;
and step S40, determining a refrigerant detection result of the air conditioner according to the condensation parameter.
In this embodiment, the steps S10 to S40 may be started when the refrigerant detection command is received. When the activation condition of the refrigerant detection function is satisfied at the current time, the steps S10 to S40 may be started to obtain the refrigerant detection result. The starting condition of the refrigerant detection function may include at least one of:
the current time point is equal to a preset refrigerant detection time point, for example, a timing detection refrigerant quantity is set, and the current time meets a timing detection time condition;
and detecting that the refrigeration effect is lower than the preset refrigeration effect.
In this embodiment, the environmental parameter corresponding to the environment where the air conditioner is located is obtained first, where the environmental parameter may include an indoor environmental temperature and an outdoor environmental temperature corresponding to the environment where the air conditioner is located. And after the indoor environment temperature and the outdoor environment temperature are obtained, obtaining operation parameters corresponding to the indoor environment temperature and the outdoor environment temperature. The operation parameters may include an operation frequency of the compressor, a rotation speed of a fan of the outdoor unit, a rotation speed of a fan of the indoor unit, and an opening degree of the electronic expansion valve. It is understood that, if the air conditioner is not provided with an electronic expansion valve, the operation parameter may not include the opening degree of the electronic expansion valve. When the operating parameter does not include the opening degree of the electronic expansion valve, the operating parameter may include a throttle coefficient of the air conditioning system.
Specifically, after the environmental parameters are obtained, the current operation mode of the air conditioner may be determined, and then the operation parameters corresponding to the operation mode are obtained according to the environmental parameters.
Example 1, after the environmental parameter is obtained, the current operation mode of the air conditioner may be obtained. After the operation mode is obtained, the comparison relationship between the environment parameter and the operation parameter associated with the operation mode can be obtained. It is understood that the comparison between the environmental parameter and the operating parameter may be stored in the air conditioner in a table form, or stored in the air conditioner in other forms of association. After the air conditioner acquires the contrast relation between the environmental parameters and the operating parameters, the corresponding operating parameters of the air conditioner can be determined according to the environmental parameters. For example, after the environmental parameters are obtained, a comparison relation table between the environmental parameters associated with the current mode and the operating parameters may be obtained, and then the operating parameters corresponding to the environmental parameters may be obtained by looking up the table according to the environmental parameters and the comparison relation table.
It should be noted that different operating modes may be associated with different environmental parameter versus operating parameter relationships, and the operating modes include a cooling mode and a heating mode.
Example 2, after the environmental parameter is obtained, the identification of the air conditioner may be obtained. The identification mark may be an identification mark used for distinguishing different types of air conditioners, such as a device ID and/or device model information of the air conditioner. After the environmental parameter and the identification mark are obtained, the identification mark and the environmental parameter can be sent to a target terminal. Wherein, the target terminal can be set as a server. And after receiving the environmental parameters and the identification marks, the target terminal can acquire the comparison relationship between the environmental parameters and the operation parameters associated with the identification marks, and then sends the operation parameters corresponding to the environmental parameters to the air conditioner as feedback data. It can be understood that, when the air conditioner does not send the current operation mode to the target terminal, the target terminal may feed back the operation parameters corresponding to the received environment parameters to the air conditioner in each of the different operation modes. If the air conditioner sends the current operation mode of the air conditioner to the target terminal before the target terminal feeds back the operation parameters, the target terminal can only feed back the operation parameters corresponding to the environmental parameters under the current mode. Further, the air conditioner may receive the operating parameter.
Further, after the air conditioner determines the operation parameters of the air conditioner corresponding to the environmental parameters, the air conditioner can operate according to the operation parameters. When the air conditioner starts to operate according to the operation parameters, a timer can be started, so that the operation time length of the air conditioner operating according to the operation parameters is counted through the timer. And when the operation time length is longer than or equal to the preset time length, the refrigerant circulating system of the air conditioner tends to be stable. Therefore, the condensing parameters of the air conditioner after the system is stabilized can be obtained. And determining a refrigerant detection result according to the condensation parameter.
Specifically, since the refrigerant circulation directions of the air conditioner are different when the air conditioner operates in different modes, when it is determined that the current operation mode is the cooling mode, the condensing temperature and/or the condensing pressure of the outdoor unit of the air conditioner can be obtained as the condensing parameters; and when the current operation mode is determined to be the heating mode, acquiring the condensation temperature and/or the condensation pressure of the indoor unit of the air conditioner as the condensation parameter.
It can be understood that the refrigerant circulation system of the air conditioner tends to be stable after the air conditioner is operated for a certain period of time according to specific operating parameters. The correlation exists between the condensing parameters of the stabilized refrigerant circulating system and the refrigerant quantity, so that the refrigerant detection result of the air conditioner can be determined according to the condensing parameters corresponding to the stabilized refrigerant circulating system. Wherein the condensation parameter may comprise a condensation temperature and/or a condensation pressure.
It should be noted that, since different types of air conditioners operate according to specific parameters, the time required for the refrigerant circulation system to reach the stable state is different, the specific value of the preset time may be set according to the type of the air conditioner, for example, the specific value of the preset time may be set to any value within 5 to 60 minutes according to the type of the air conditioner. For example, 10 minutes, 15 minutes, 25 minutes, 35 minutes, or the like may be set.
And after the refrigerant detection result of the air conditioner is determined, outputting the refrigerant detection result. Wherein, the output mode can comprise pushing to the control terminal or directly displaying in the display device of the air conditioner.
In the technical scheme disclosed in this embodiment, an operation parameter of an air conditioner corresponding to an environment parameter of an environment where the air conditioner is located is obtained, then the air conditioner is controlled to operate according to the operation parameter, an operation time period for the air conditioner to operate according to the operation parameter is determined to be greater than or equal to a preset time period, a condensation parameter of the air conditioner is obtained, the condensation parameter includes at least one of a condensation temperature and a condensation pressure, and a refrigerant detection result of the air conditioner is determined according to the condensation parameter. The air conditioner runs for a preset time according to the specific parameters, the refrigerant circulating system tends to be stable, and the condensation parameters change due to the change of the refrigerant quantity after the refrigerant circulating system is stable, so that the current refrigerant detection result of the air conditioner can be determined according to the detected condensation parameters, the refrigerant detection result can be obtained on the premise of not disassembling the air conditioner, and the effect of simplifying the refrigerant quantity detection step of the air conditioner is achieved.
Referring to fig. 3, based on the above embodiment, in another embodiment, the step S40 includes:
step S41, acquiring a difference value between the condensation parameter of the air conditioner and a preset reference condensation parameter;
and step S42, determining the current refrigerant leakage amount of the air conditioner according to the difference value, wherein the refrigerant detection result comprises the refrigerant leakage amount.
In this embodiment, after the condensation parameter of the air conditioner is obtained, a preset reference condensation parameter corresponding to the environmental parameter may also be obtained. Wherein the reference condensing parameter is determined according to a hardware parameter of the air conditioner. When the hardware parameters of the air conditioner are different, the reference condensation parameters are also different. The reference condensing parameter can be directly stored in a storage medium of the air conditioner, so that the air conditioner can directly read the reference condensing parameter. Or the reference condensation parameter can be stored in the server, and when the air conditioner needs to acquire the condensation parameter corresponding to the air conditioner, the identification mark corresponding to the air conditioner can be sent to the server, so that the server can determine the reference condensation parameter corresponding to the air conditioner according to the identification mark and then feed the reference condensation parameter back to the air conditioner.
After the reference condensation parameter is obtained, a difference value between the reference condensation parameter and the currently obtained condensation parameter can be calculated, then the current refrigerant leakage amount of the air conditioner is determined according to the difference value, and the current refrigerant leakage amount is used as the refrigerant detection result.
Specifically, when determining the current refrigerant leakage amount of the air conditioner according to the difference, a comparison table between the difference and the refrigerant leakage amount may be obtained first, and the refrigerant leakage amount corresponding to the difference may be obtained according to the comparison table and used as the current refrigerant leakage amount of the air conditioner. Or, the difference value may be sent to a target terminal, so that after receiving the difference value, the target terminal feeds back the refrigerant leakage amount corresponding to the difference value to the air conditioner, receives the refrigerant leakage amount fed back by the target terminal, and uses the refrigerant leakage amount as the current refrigerant leakage amount of the air conditioner.
In the technical scheme disclosed in this embodiment, the current refrigerant leakage amount of the air conditioner can be determined by the difference between the condensation parameter and the preset reference condensation parameter, so that when the refrigerant leakage phenomenon occurs, the leakage amount of the refrigerant can be directly determined, and the refrigerant supplement operation is performed according to the refrigerant leakage amount, thereby overcoming the defects of environment pollution and refrigerant waste caused by supplementing the preset amount of refrigerant after the refrigerant is completely emptied in the conventional refrigerant supplement process so as to enable the refrigerant to be supplemented to an optimal value, and improving the effect of saving the amount of the refrigerant needed in the refrigerant supplement process while protecting the environment.
Referring to fig. 4, based on the corresponding embodiment of fig. 2, the step S40 includes:
step S43, obtaining a relation comparison table between the condensation parameter and the refrigerant quantity, and obtaining the refrigerant quantity corresponding to the condensation parameter as the current refrigerant quantity of the air conditioner according to the comparison table;
in this embodiment, after the condensing parameter is determined, a comparison table of a relationship between the condensing parameter and a refrigerant quantity may be obtained, and then the refrigerant quantity corresponding to the condensing parameter is obtained as the current refrigerant quantity of the air conditioner by looking up the table based on the comparison table.
Optionally, referring to fig. 5, in another implementation manner of this embodiment, the step S40 includes:
step S44, the condensation parameters are sent to a target terminal, so that after the target terminal receives the condensation parameters, the refrigerant quantity corresponding to the condensation parameters is fed back to the air conditioner;
and step S45, receiving the refrigerant quantity fed back by the target terminal, and taking the refrigerant quantity as the current refrigerant quantity of the air conditioner.
In this embodiment, after the condensation parameter is determined, the condensation parameter may be sent to a target terminal, so that the target terminal determines the refrigerant amount corresponding to the condensation parameter based on the environmental parameter after receiving the condensation parameter, and then feeds the refrigerant amount back to the air conditioner. After receiving the refrigerant quantity, the air conditioner may use the received refrigerant quantity as a refrigerant detection result of the air conditioner.
For example, when the operation mode of the air conditioner is the cooling mode, under different environmental parameters, the correspondence between the condensing parameter and the refrigerant quantity may be as shown in table 1 below:
TABLE 1
Wherein the first corresponding relationship is shown in the following Table 2
| Amount of refrigerant | Condensing pressure | Condensation temperature |
| 1000g | 39 | P1 |
| 900g | 38 | P2 |
| 500g | 36 | P3 |

| 1000g | 48 | P3 |
| 900g | 47 | P4 |
| 500g | 45 | P3 |
