It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the disclosure described herein may be capable of operation in sequences other than those illustrated or described herein. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure.

The following describes a method for detecting leakage of a refrigerant of an air conditioner, a device for detecting leakage of a refrigerant of an air conditioner, an air conditioner control device, an air conditioner, and a computer readable storage medium according to embodiments of the present disclosure with reference to the accompanying drawings.
Before describing the method for detecting the refrigerant leakage of the air conditioner according to the embodiment of the present disclosure, an application scenario of the method for detecting the refrigerant leakage of the air conditioner according to the embodiment of the present disclosure will be described.
Application scene: after the user uses the air conditioner for a period of time, the air conditioner leaks the refrigerant, and the leakage speed is slower, and the user can not very fast perceive that the refrigerant leaks, and the air conditioner also can adjust room temperature to user's settlement state, but adjustment time obviously prolongs, and the air conditioner has been worked at relatively unstable state this moment.
The detection method of the refrigerant leakage of the air conditioner in the current market is low in accuracy, particularly when the refrigerant quantity leakage is not large and the influence on the air conditioner is small, therefore, the present disclosure provides a new detection method of the refrigerant leakage of the air conditioner, and the method detects whether the refrigerant is leaked according to the obtained actual operation time length and the reference operation time length of the air conditioner, so that the detection accuracy and timeliness can be improved, and the use experience of a user is ensured.
Fig. 1 is a flowchart of a method of detecting leakage of a refrigerant of an air conditioner according to an embodiment of the present disclosure.
It should be noted that, the execution main body of the method for detecting the leakage of the refrigerant of the air conditioner in the embodiment of the disclosure is a device for detecting the leakage of the refrigerant of the air conditioner, and the detection device can be configured in the air conditioner control device, so that the air conditioner control device can execute the function of detecting the leakage of the refrigerant of the air conditioner.
As shown in fig. 1, a method for detecting refrigerant leakage of an air conditioner according to an embodiment of the disclosure includes the following steps:
s101, after the air conditioner is started to operate, acquiring environment parameters, operation parameters and preset parameters of the air conditioner.
Wherein the environmental parameters include: at least one of room area, number of people in the room, and ambient temperature; operating parameters, including: at least one of the rotating speed of the fan, the opening and closing angle of the air deflector and the running mode; the preset parameters comprise: the temperature is preset.
In this step, the room area may be input by a user through the remote controller or the interactive interface on the air conditioner body after the air conditioner is installed; the number of the rooms can be obtained through a camera installed on the air conditioner, for example, an image of the whole room is shot through the camera, and then the number of the people in the image is detected as the number of the rooms; the room temperature may be obtained by a temperature sensor mounted on the air conditioner.
After the air conditioner is started to operate, if a user does not adjust the rotating speed of a fan, the opening and closing angle of an air deflector, the operation mode and the preset temperature of the air conditioner, the air conditioner operates in the rotating speed of the fan, the opening and closing angle of the air deflector and the operation mode when the air conditioner is shut down last time, and the target temperature is the preset temperature; if the user adjusts at least one of the fan rotating speed, the air deflector opening and closing angle and the operation mode of the air conditioner, the adjusted fan rotating speed, the air deflector opening and closing angle and the operation mode are used as the operation parameters of the air conditioner, and the adjusted target temperature is used as the preset parameters of the air conditioner.
As a preferred embodiment, after the air conditioner is started to operate, the area of a room where the air conditioner is installed, the number of people in the room, the ambient temperature, the rotating speed of a fan, the opening and closing angle of an air deflector, the operation mode and the preset temperature are obtained.
S102, acquiring the actual operation time length of the air conditioner from the starting operation to the state set by a user; the user setting state is used for representing the state that the air conditioner runs with the running parameters to reach the preset parameters under the condition of the environmental parameters.
In the step, after the air conditioner control device obtains the environmental parameter, the operation parameter and the preset parameter of the air conditioner, the environmental parameter, the operation parameter and the preset parameter of the air conditioner are recorded into the data storage module, the timer is controlled to be synchronously started for timing, when the air conditioner is operated with the operation parameter under the condition of the environmental parameter and reaches the state of the preset parameter, the timing is stopped, and the actual operation time of the air conditioner from the starting operation to the state of the user setting can be obtained, and is recorded as T1.
S103, acquiring a reference operation time length according to the environmental parameter, the operation parameter and the preset parameter; the reference operation time length is used for representing the operation time length when the air conditioner refrigerant is not leaked, and the air conditioner is operated with the operation parameters under the condition of the environmental parameters until the operation time length reaches the preset parameter state.
It should be noted that, through multiple experiments, under the condition that the refrigerant of the air conditioner is not leaked, controlling the air conditioner to operate to different preset parameters with different operation parameters under different environment parameters, namely, taking the operation parameters as reference operation time and generating a reference operation time table, wherein the reference operation time table can be stored locally or in the cloud.
When the reference operation time length table is stored locally, the air conditioner invokes the local reference operation time length table after acquiring the environmental parameter, the operation parameter and the preset parameter, and acquires the corresponding reference operation time length by a table look-up mode, and records as T2.
When the reference operation time table is stored in the cloud, the air conditioner sends the environment parameters, the operation parameters and the preset parameters to the cloud after acquiring the environment parameters, the operation parameters and the preset parameters. The cloud terminal invokes the reference operation time length table, acquires the corresponding reference operation time length in a table look-up mode and feeds the reference operation time length back to the air conditioner. After the air conditioner obtains the reference operation time, the reference operation time is saved and is recorded as T2.
It can be understood that if the obtained reference operation time length table includes parameters of a room area where the air conditioner is installed, the number of people in the room, the ambient temperature, the rotation speed of the fan, the opening and closing angle of the air deflector, the operation mode and the preset temperature, the corresponding reference operation time length T2 obtained according to the reference operation time length table is more accurate.
S104, detecting whether the refrigerant leaks or not according to the actual operation time and the reference operation time.
In the step, after the air conditioner control device obtains T1 and T2, comparing the difference between the T1 and the T2, and judging that the refrigerant of the air conditioner leaks when the difference between the T1 and the T2 exceeds a certain value. For example, when 1.2T2 is less than or equal to T1 is less than or equal to 1.5T2, adding 1 to the refrigerant leakage zone bit value N (N=0 in the initial stage), and when N is more than or equal to 3, judging that the air conditioner has the condition of slow refrigerant leakage; when T1 is larger than 1.5T2, judging that the air conditioner has the condition of quick leakage of the refrigerant. Under the two conditions, the air conditioner reminds a user that the air conditioner possibly has refrigerant leakage and leakage conditions in a voice or display mode and reminds the user of maintenance.
The method for detecting the leakage of the air conditioner refrigerant comprises the steps of firstly acquiring environment parameters, operation parameters and preset parameters of the air conditioner after the air conditioner is started to operate, then acquiring actual operation time of the air conditioner from the starting operation until the air conditioner reaches a user setting state, wherein the user setting state is used for representing that the air conditioner is operated with the operation parameters to reach the state of the preset parameters under the condition of the environment parameters, acquiring reference operation time according to the environment parameters, the operation parameters and the preset parameters, and detecting whether the refrigerant leaks or not according to the actual operation time and the reference operation time when the reference operation time is used for representing that the air conditioner refrigerant is not leaked under the condition of the environment parameters, and operating with the operation parameters until the operation time when the operation parameters reach the state of the preset parameters. Therefore, the method detects whether the refrigerant leaks according to the acquired actual operation time length and the reference operation time length of the air conditioner, so that the accuracy and timeliness of detection can be improved, and the use experience of a user is ensured.
Fig. 2 is a flowchart of a method of detecting leakage of a refrigerant of an air conditioner according to an embodiment of the present disclosure.
As shown in fig. 2, a method for detecting refrigerant leakage of an air conditioner according to an embodiment of the disclosure includes:
S201, after the air conditioner is started to operate, acquiring the environment parameters, the operation parameters and the preset parameters of the air conditioner.
S202, acquiring the actual operation time length of the air conditioner from the starting operation to the state set by a user; the user setting state is used for representing the state that the air conditioner runs with the running parameters to reach the preset parameters under the condition of the environmental parameters.
S203, acquiring a reference operation time length according to the environment parameter, the operation parameter and the preset parameter; the reference operation time length is used for representing the operation time length when the air conditioner refrigerant is not leaked, and the air conditioner is operated with the operation parameters under the condition of the environmental parameters until the operation time length reaches the preset parameter state.
It should be noted that, for the execution of the steps S201 to S203, refer to details disclosed in the steps S101 to S103, and detailed descriptions thereof are omitted here. And, after step S203 is performed, step S204 or S205 or S207 is selectively performed according to the relationship between T1 and T2.
S204, if the actual operation duration is smaller than the first multiple of the reference operation duration, stopping detection.
S205, if the actual running time length is greater than or equal to the first multiple of the reference running time length and is less than or equal to the second multiple of the reference running time length, adding 1 to the refrigerant leakage flag bit value; wherein the first multiple is less than the second multiple.
The first multiple and the second multiple may be set according to practical needs, for example, the first multiple may range from [1.1,1.3], preferably 1.2, and the second multiple may range from [1.4,1.6], preferably 1.5.
S206, judging whether the refrigerant leakage zone bit value after adding 1 is larger than or equal to the set zone bit value.
The flag bit value may be set according to actual needs, for example, may be 3.
S207, if yes, determining that the air conditioner has a slow refrigerant leakage condition.
In steps S205 to S207, the air conditioner control device, after obtaining T1 and T2, adds 1 to the refrigerant leakage flag bit value N (initially n=0) if 1.2T2 is equal to or less than T1 is equal to or less than 1.5T2. After the refrigerant leakage zone bit value N is added with 1 each time, judging the refrigerant leakage zone bit value after the 1 is added, and if the refrigerant leakage zone bit value after the 1 is added is greater than or equal to a set zone bit value (if N is more than or equal to 3), determining that the refrigerant of the air conditioner leaks slowly.
It should be noted that, the refrigerant leakage flag bit value is not cleared after shutdown, but is cleared after the user adds refrigerant or is checked by professional personnel.
And S208, if the actual operation time length is larger than the second multiple of the reference operation time length, determining that the air conditioner has the condition of rapid leakage of the refrigerant.
In the step, after T1 and T2 are obtained, if T1 is larger than 1.5T2, the air conditioner control device judges that the air conditioner has the condition of rapid leakage of the refrigerant.
S209, sending out first reminding information; the first reminding information is used for representing information for reminding a user of refrigerant leakage conditions.
In the step, the air conditioner control device sends out first reminding information for reminding a user of refrigerant leakage in a voice or display mode under the condition that the refrigerant is determined to leak slowly or quickly.
For example, when the air conditioner determines that the refrigerant leaks slowly, the player is controlled to play the refrigerant slowly, and the maintenance is requested in time, and/or the display screen is controlled to display the refrigerant slowly, and the maintenance is requested in time; the air conditioner controls the player to play the refrigerant fast leakage, and timely maintain the refrigerant fast leakage under the condition that the refrigerant fast leakage is determined, and/or controls the display screen to display the refrigerant fast leakage, and timely maintain the refrigerant fast leakage.
Therefore, the detection method for the leakage of the air conditioner refrigerant detects whether the refrigerant leaks and the leakage condition by comparing the acquired relation between the actual operation time length and the reference operation time length of the air conditioner, reminds a user of whether the refrigerant leaks and the leakage condition in a voice or display mode, reminds the user of maintenance, and accordingly can improve detection accuracy and timeliness, prevent the problem of refrigerant leakage when the air conditioner operates, ensure that the air conditioner operates in an optimal state and ensure use experience of the user.
In order to further improve the accuracy of detecting whether the refrigerant leaks, according to the above embodiment, as shown in fig. 3, before the environmental parameters, the operation parameters, and the preset parameters of the air conditioner are obtained in step S102 or S201, the method further includes:
S301, acquiring images of doors and windows of a room where the air conditioner is located.
For example, an image of a door or window of a room in which the air conditioner is located may be acquired by a camera provided on the air conditioner.
After step S301 is performed, step S302 or step S303 is performed.
S302, determining that doors and windows are in a closed state according to the images.
In this step, after the image is obtained, each door and window in the image is identified to determine the state of the door and window, and if all the doors and windows are in the closed state, step S102 or S201 is performed.
S303, determining that at least one of the doors and windows is in an open state according to the image.
S304, sending out second reminding information; the second reminding information is used for representing information for reminding a user to close the door and window.
In steps S303 and S304, after the image is obtained, each door and window in the image is identified to determine the state of the door and window, and if at least one door and window is in an open state, a second reminding message for reminding the user to close the door and window is sent.
That is, after the user opens the air conditioner and operates, the air conditioner control device detects the opening and closing state of the door and window in the current environment, and if the user is detected that the door and window is not closed, the second reminding information is sent out in a voice or display mode to remind the user to ensure that the door and window is in a closed state so as to ensure a good detection effect, and in the state, the air conditioner is not controlled to enter a refrigerant leakage detection mode until the detection condition is met.
Therefore, the detection of the door and window is increased, the refrigerant leakage detection mode is not entered when the door and window is not closed, and the reminding information is sent out to remind a user to close the door and window, so that the air conditioner operates in a relatively closed space, and the accuracy of detecting whether the refrigerant leaks can be further improved.
Fig. 4 is a flowchart of a method of detecting leakage of a refrigerant of an air conditioner according to an embodiment of the present disclosure.
As shown in fig. 4, a method for detecting refrigerant leakage of an air conditioner according to an embodiment of the disclosure includes the following steps:
