Detailed Description
In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in other sequences than those illustrated or described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
A method for detecting air conditioner refrigerant leakage, an apparatus for detecting air conditioner refrigerant leakage, an air conditioner control device, an air conditioner, and a computer-readable storage medium according to embodiments of the present disclosure are described below with reference to the accompanying drawings.
Before the method for detecting air conditioner refrigerant leakage according to the embodiment of the present disclosure is introduced, an application scenario of the method for detecting air conditioner refrigerant leakage according to the embodiment of the present disclosure is introduced.
Application scenarios: after a user uses the air conditioner for a period of time, the air conditioner leaks the refrigerant, the leakage speed is slow, the user cannot quickly detect that the refrigerant leaks, the air conditioner can adjust the room temperature to a state set by the user, but the adjustment time is obviously prolonged, and the air conditioner works in a relatively unstable state at the moment.
The method for detecting the refrigerant leakage of the air conditioner in the mainstream in the market at present has low accuracy, and particularly when the refrigerant leakage is not large and the influence on the air conditioner is small, therefore, the method for detecting the refrigerant leakage of the air conditioner is provided.
Fig. 1 is a flowchart illustrating a method for detecting refrigerant leakage of an air conditioner according to an embodiment of the present disclosure.
It should be noted that the main implementation of the method for detecting air conditioner refrigerant leakage according to the embodiment of the present disclosure is a detection device for air conditioner refrigerant leakage, and the detection device may be configured in an air conditioner control device, so that the air conditioner control device may implement a function of detecting air conditioner refrigerant leakage.
As shown in fig. 1, the method for detecting refrigerant leakage of an air conditioner according to the embodiment of the present disclosure includes the following steps:
s101, after the air conditioner is started to operate, acquiring environmental parameters, operating parameters and preset parameters of the air conditioner.
Wherein, the environmental parameters comprise: at least one of room area, number of rooms, and ambient temperature; operating parameters comprising: at least one of fan speed, air deflector opening and closing angle and operation mode; presetting parameters, including: the temperature is preset.
In this step, the room area can be input by the user through the remote controller or the interactive interface on the air conditioner body after the air conditioner is installed; the number of the persons in the room can be obtained by a camera arranged on the air conditioner, for example, an image of the whole room is shot by the camera, and then the number of the persons in the image is detected as the number of the persons in the room; the room temperature may be acquired by a temperature sensor installed on the air conditioner.
After the air conditioner is started to operate, if a user does not adjust the fan rotating speed, the air deflector opening and closing angle, the operation mode and the preset temperature of the air conditioner, the fan rotating speed, the air deflector opening and closing angle and the operation mode of the air conditioner during the last shutdown of the air conditioner are operated, 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 running time of the air conditioner from the starting to the running until the air conditioner reaches the state set by the user; the user setting state is used for representing the state that the air conditioner reaches the preset parameter by the operation of the operation parameter under the condition of the environmental parameter.
In the step, after acquiring the environmental parameters, the operating parameters and the preset parameters of the air conditioner, the air conditioner control device records the environmental parameters, the operating parameters and the preset parameters of the air conditioner into the data storage module, and at this time, the timer is controlled to start timing synchronously, and when the air conditioner is in the environmental parameters and the operating parameters reach the preset parameter state, the timing is stopped, so that the actual operating time length of the air conditioner from the start to the time when the air conditioner reaches the user-set state can be acquired and recorded as T1.
S103, acquiring reference operation duration according to the environment parameters, the operation parameters and preset parameters; the reference operation time length is used for representing the operation time length when the refrigerant of the air conditioner is not leaked and the operation parameter is operated until the preset parameter state is reached under the condition of the environmental parameter.
It should be noted that, through multiple tests, under the condition that the refrigerant of the air conditioner is not leaked, the air conditioner is controlled to operate to different preset parameters with different operation parameters for a required time duration under different environmental parameters, that is, as a reference operation time duration, and a reference operation time duration table is generated, wherein the reference operation time duration table can be stored locally or in a cloud.
When the reference operation time length table is stored locally, the air conditioner calls the local reference operation time length table after acquiring the environmental parameters, the operation parameters and the preset parameters, and acquires the corresponding reference operation time length in a table look-up mode, wherein the reference operation time length table is recorded as T2.
When the reference running long table is stored in the cloud, the air conditioner sends the reference running long table to the cloud after acquiring the environmental parameters, the running parameters and the preset parameters. And the cloud calls a 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 obtaining the reference operation time length, the air conditioner saves the reference operation time length and records as T2.
It can be understood that, if the obtained reference operation time length table includes parameters of the room area where the air conditioner is installed, the number of the room people, the ambient temperature, the fan rotating speed, 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 relatively accurate.
And S104, detecting whether the refrigerant leaks or not according to the actual operation duration and the reference operation duration.
In this step, the air conditioner control device compares the difference between T1 and T2 after obtaining the difference, and determines that refrigerant leakage occurs in the air conditioner when the difference exceeds a certain value. For example, when 1.2T2 ≦ T1 ≦ 1.5T2, the refrigerant leakage flag value N is added with 1 (initially, N is 0), and when N ≧ 3, it is determined that the air conditioner has the refrigerant slow leakage; and when the T1 is more than 1.5T2, judging that the air conditioner has the condition of quick refrigerant leakage. 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 to overhaul.
Therefore, the method for detecting the refrigerant leakage of the air conditioner comprises the steps of firstly obtaining the environmental parameters, the operation parameters and the preset parameters of the air conditioner after the air conditioner is started to operate, then obtaining the actual operation time length of the air conditioner from the starting operation to the time when the air conditioner reaches the user set state, enabling the user set state to be used for representing the state that the air conditioner reaches the preset parameters in the operation parameter mode under the condition of the environmental parameters, obtaining the reference operation time length according to the environmental parameters, the operation parameters and the preset parameters, enabling the reference operation time length to be used for representing the time when the refrigerant of the air conditioner is not leaked, enabling the operation parameter to be used for representing the operation time length of the air conditioner till the time when the refrigerant of the preset parameters reaches the state under the condition of the environmental parameters, and finally detecting whether the refrigerant is leaked or not according to the actual operation time length and the reference operation time length. Therefore, whether the refrigerant leaks or not is detected according to the obtained 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 guaranteed.
Fig. 2 is a flowchart illustrating a method for detecting refrigerant leakage of an air conditioner according to an embodiment of the disclosure.
As shown in fig. 2, the method for detecting refrigerant leakage of an air conditioner according to the embodiment of the present disclosure includes:
s201, after the air conditioner is started to operate, acquiring environmental parameters, operating parameters and preset parameters of the air conditioner.
S202, acquiring the actual running time of the air conditioner from starting to running until reaching the state set by the user; the user setting state is used for representing the state that the air conditioner runs to reach the preset parameters according to the running parameters under the condition of environmental parameters.
S203, acquiring reference operation duration according to the environment parameters, the operation parameters and the preset parameters; the reference operation time length is used for representing the operation time length when the refrigerant of the air conditioner is not leaked and the operation parameter is operated until the preset parameter state is reached under the condition of the environmental parameter.
It should be noted that, the execution process of the steps S201 to S203 refers to the details disclosed in the steps S101 to S103, and detailed description thereof is omitted here. And, after the step S203 is performed, the step S204 or S205 or S207 is selectively performed according to the relationship of both T1 and T2.
And S204, if the actual running time is less than the first multiple of the reference running time, stopping detection.
S205, if the actual running time is greater than or equal to the first multiple of the reference running time and less than or equal to the second multiple of the reference running time, adding 1 to the refrigerant leakage flag value; wherein the first multiple is less than the second multiple.
The first multiple and the second multiple may be set according to actual needs, for example, the first multiple may be in the range of [1.1, 1.3], preferably 1.2, and the second multiple may be in the range of [1.4, 1.6], preferably 1.5.
And S206, judging whether the refrigerant leakage flag value added with 1 is greater than or equal to the set flag value.
The setting flag bit value can be set according to actual needs, and may be 3, for example.
And S207, if so, 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, increments the refrigerant leakage flag value N by 1 (initially N is 0) if 1.2T2 ≦ T1 ≦ 1.5T 2. And judging the refrigerant leakage flag bit value after adding 1 to the refrigerant leakage flag bit value N every time, and if the refrigerant leakage flag bit value after adding 1 is greater than or equal to a set flag bit value (if N is greater than or equal to 3), determining that the air conditioner has the condition of slow refrigerant leakage.
It should be noted that the refrigerant leakage flag value is not cleared after shutdown, but is cleared after a user adds a refrigerant or a professional checks that no error is found.
And S208, if the actual operation time is more than the second multiple of the reference operation time, determining that the air conditioner has the refrigerant quick leakage condition.
In this step, the air conditioner controlling apparatus judges that the air conditioner has the rapid refrigerant leakage if T1 > 1.5T2 after obtaining T1 and T2.
S209, sending out first reminding information; the first reminding information is used for representing information for reminding a user of the refrigerant leakage condition.
In the step, the air conditioner control device sends out first reminding information for reminding a user of the refrigerant leakage condition in a voice or display mode under the condition that the refrigerant is determined to be leaked slowly or quickly.
For example, the air conditioner controls the player to play the 'refrigerant leakage occurs slowly and needs to be maintained in time' and/or controls the display screen to display the 'refrigerant leakage occurs slowly and needs to be maintained in time' when the air conditioner determines that the refrigerant leaks slowly; the air conditioner controls the player to play the steps of 'quick leakage of the refrigerant and prompt maintenance' and/or controls the display screen to display the steps of 'quick leakage of the refrigerant and prompt maintenance'.
Therefore, according to the detection method for the refrigerant leakage of the air conditioner, whether the refrigerant leaks or not and the leakage condition are detected by comparing the obtained relation between the actual operation time length and the reference operation time length of the air conditioner, and whether the refrigerant leaks or not and the leakage condition are reminded to a user in a voice or display mode, and the user is reminded of overhauling, so that the detection accuracy and timeliness can be improved, the problem of refrigerant leakage during the operation of the air conditioner is prevented, the air conditioner is guaranteed to operate in the best state, and the use experience of the user is guaranteed.
In order to further improve the accuracy of detecting whether the refrigerant leaks, as shown in fig. 3, before the acquiring the environmental parameter, the operating parameter, and the preset parameter of the air conditioner in step S102 or S201, the method further includes:
s301, acquiring an image of a door and a window of a room where the air conditioner is located.
For example, the image of the door and window of the room where the air conditioner is located can be acquired through a camera arranged on the air conditioner.
After step S301 is executed, step S302 or S303 is executed.
And S302, determining that the doors and windows are in a closed state according to the image.
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 executed.
S303, determining that at least one door or window 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 in all the doors and windows is in an open state, second reminding information for reminding a user to close the door and window is sent out.
That is to say, after the user opened the air conditioner operation, air conditioner controlgear detected the on-off state of current environment door and window earlier, if detected user's door and window not closed, can send the second with pronunciation or the form that shows and remind the user to guarantee that door and window are in the closed condition, in order to guarantee better detection effect, and under this state, can not control the air conditioner and get into refrigerant and reveal the detection mode, until satisfying the detection condition.
From this, through the detection that increases door and window to when door and window do not close, not get into the refrigerant and reveal the detection mode, and send out warning information, close door and window with reminding the user, make the air conditioner operation like this in relative airtight space, can further improve the accuracy of detecting whether the refrigerant reveals.
Fig. 4 is a flowchart illustrating a method for detecting refrigerant leakage of an air conditioner according to an embodiment of the disclosure.
As shown in fig. 4, the method for detecting refrigerant leakage of an air conditioner according to the embodiment of the present disclosure includes the following steps:
s401, after the air conditioner is started to operate, whether the door and the window are closed or not is judged. If yes, go to step S402; if not, step S408 is performed.
And S402, collecting parameters. For example, environmental parameters, operational parameters, and preset parameters of the air conditioner are collected. Wherein, the environmental parameters comprise: at least one of room area, number of room people, and ambient temperature; operating parameters comprising: at least one of fan speed, air deflector opening and closing angle and operation mode; presetting parameters, including: the temperature is preset.
