The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the present invention and should not be construed as limiting the present application.
An air conditioner and a control method and apparatus thereof according to an embodiment of the present application are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart illustrating a method for controlling an air conditioner according to an embodiment of the present disclosure. As shown in fig. 1, the method for controlling an air conditioner according to the embodiment of the present application specifically includes the following steps:
s101, recognizing that the working time of the air conditioner in the target operation mode reaches a preset time.
The target operation mode in this embodiment may be, but is not limited to, a cooling mode or a heating mode. During the operation of the air conditioner, a timer such as a timer can be used to record the working time of the air conditioner in a target operation mode (such as a cooling mode). And when the time length recorded by the timer reaches the preset time length, recognizing that the time length of the air conditioner working in the target operation mode reaches the preset time length.
It should be noted that the preset time period may be set according to an actual situation, wherein the preset time period may be, but is not limited to: the air quality in the room is reduced to the average time length required by the second air quality from the first air quality when the air conditioner is started every time in the preset time period.
And S102, acquiring the outdoor return air temperature and the indoor return air temperature of the air conditioner.
Wherein, can utilize temperature-detecting device such as temperature sensor, detect the outdoor return air temperature and the indoor return air temperature of air conditioner.
Optionally, a temperature detection device is disposed in both the outdoor return air channel and the indoor return air channel of the air conditioner.
And S103, controlling a fresh air assembly in the air conditioner to be opened or closed according to the target operation mode, the outdoor return air temperature and the indoor return air temperature.
Wherein, determine the target operation mode, outdoor return air temperature and indoor return air temperature, just can be according to the target operation mode, outdoor return air temperature and indoor return air temperature, the new trend subassembly in the control air conditioner is opened or is closed, make the target operation mode, outdoor return air temperature, the running state phase-match of indoor return air temperature and new trend subassembly, the frequent condition to new trend subassembly control of user has been avoided, the convenience of control has been promoted, and the poor phenomenon of air conditioner travelling comfort because of the new trend subassembly has been opened and has been leaded to has been avoided, the comfort performance of air conditioner has been promoted.
As a possible implementation, as shown in fig. 2, the method includes the following steps:
s201, identifying that the target operation mode is a refrigeration mode.
During the operation process of the air conditioner, the target operation mode of the air conditioner can be determined according to the mode adjusting instruction received by the air conditioner last time. For example, when the last received mode adjustment command is to control the air conditioner to adjust from the heating mode to the cooling mode, it may be determined that the target operation mode is the cooling mode.
S202, judging whether the outdoor return air temperature is greater than or equal to a first temperature threshold value.
After the target operation mode is determined to be the refrigeration mode, whether the outdoor return air temperature is larger than or equal to a first temperature threshold value or not is judged. When the outdoor return air temperature is greater than or equal to the first temperature threshold, executing step S203; otherwise, step S206 is executed.
And S203, judging whether the indoor return air temperature is greater than a second temperature threshold value.
And when the outdoor return air temperature is determined to be greater than or equal to the first temperature threshold, judging the magnitude relation between the indoor return air temperature and the second temperature threshold. When the outdoor return air temperature is greater than or equal to the first temperature threshold value, the outdoor environment is hot, and at the moment, a user usually expects that the indoor temperature is rapidly reduced after starting the air conditioner so as to cool the indoor space; when the fresh air assembly is started, if the indoor return air temperature is high and is influenced by outdoor high-temperature air, the time length of the indoor temperature reduction can be prolonged, which is contrary to the expectation of a user; in addition, when opening the new trend subassembly, if indoor return air temperature is lower, then outdoor high temperature air gets into indoor back, can accomplish the heat exchange with indoor low temperature air very fast, and at this moment under the effect of air conditioner, indoor temperature can not produce big fluctuation, and the user is difficult to perceive the change of temperature.
Therefore, in this embodiment, when the outdoor return air temperature is greater than or equal to the first temperature threshold and the indoor return air temperature is greater than the second temperature threshold, the fresh air component is controlled to be closed, that is, step S204 is executed; when the outdoor return air temperature is greater than or equal to the first temperature threshold value and the indoor return air temperature is less than or equal to the second temperature threshold value, the fresh air assembly is controlled to be started, and step S205 is executed. Wherein the first temperature threshold is greater than the second temperature threshold.
And S204, controlling the fresh air component to be closed.
S205, controlling the fresh air component to be started.
And S206, judging whether the outdoor return air temperature is greater than a third temperature threshold value.
And when the outdoor return air temperature is determined to be smaller than the first temperature threshold value, judging the magnitude relation between the outdoor return air temperature and the third temperature threshold value. When the outdoor return air temperature is lower than the first temperature threshold and higher than the third temperature threshold, it indicates that the temperature of the outdoor air is relatively high, and at this time, the indoor return air temperature needs to be continuously determined, that is, step S207 is executed. And when the outdoor return air temperature is less than or equal to the third temperature threshold, the outdoor environment is relatively suitable, and the indoor and outdoor temperature difference is relatively small, so that the fresh air component can be directly controlled to be started, namely the step S205 is executed.
And S207, judging whether the indoor return air temperature is greater than a fourth temperature threshold value.
When the outdoor return air temperature is between the first temperature threshold and the third temperature threshold, the indoor return air temperature and the fourth temperature threshold are compared, and the size relation between the indoor return air temperature and the fourth temperature threshold can be determined. When the indoor return air temperature is higher than the fourth temperature threshold value, the fresh air assembly is started and is influenced by outdoor high-temperature air, so that the time length of indoor temperature reduction can be prolonged, and the indoor return air temperature is contrary to the expectation of a user; when the indoor return air temperature is less than or equal to the fourth temperature threshold value, because the indoor return air temperature is lower, the outdoor high-temperature air can quickly finish heat exchange with the indoor low-temperature air after entering the room, and at the moment, under the action of the air conditioner, the indoor temperature cannot generate large fluctuation, and the user cannot easily perceive the temperature change.
Therefore, in this embodiment, when the outdoor return air temperature is less than the first temperature threshold and the outdoor return air temperature is greater than the third temperature threshold, if the indoor return air temperature is greater than the fourth temperature threshold, the fresh air component is controlled to be closed, that is, step S204 is executed; and if the indoor return air temperature is less than or equal to the fourth temperature threshold value, controlling the fresh air assembly to be started, namely executing the step S205. Wherein the third temperature threshold is greater than the fourth temperature threshold.
Optionally, when the outdoor return air temperature is relatively low, it indicates that it is relatively comfortable outdoors, and therefore the influence of the air entering the room from the outside on the indoor air is relatively small, and therefore in this embodiment, the second temperature threshold may be selected to be smaller than the fourth temperature threshold, so as to update the indoor air by using the fresh air component earlier, and improve the comfort of the indoor environment.
As another possible implementation, as shown in fig. 3, the method includes the following steps:
s301, identifying the target operation mode as a heating mode.
During the operation process of the air conditioner, the target operation mode of the air conditioner can be determined according to the mode adjusting instruction received by the air conditioner last time. For example, when the last received mode adjustment command is to control the air conditioner to adjust from the cooling mode to the heating mode, the target operation mode may be determined to be the heating mode.
And S302, judging whether the outdoor return air temperature is less than or equal to a fifth temperature threshold value.
And after the target operation mode is determined to be the heating mode, judging whether the outdoor return air temperature is less than or equal to a fifth temperature threshold value. When the outdoor return air temperature is less than or equal to the fifth temperature threshold, executing step S303; otherwise, step S306 is executed.
And S303, judging whether the indoor return air temperature is greater than or equal to a sixth temperature threshold value.
And when the outdoor return air temperature is determined to be less than or equal to the fifth temperature threshold, judging the magnitude relation between the indoor return air temperature and the sixth temperature threshold. When the outdoor return air temperature is less than or equal to the fifth temperature threshold value, the outdoor environment is relatively cold, and at the moment, a user usually expects the indoor temperature to rise rapidly after starting the air conditioner so as to warm the indoor space; when the fresh air assembly is started, if the indoor return air temperature is low and is influenced by outdoor low-temperature air, the indoor temperature rise time can be prolonged, which is contrary to the expectation of users; in addition, when opening the new trend subassembly, if indoor return air temperature is higher, then outdoor low temperature air gets into indoor back, can accomplish the heat exchange with indoor high temperature air very fast, and at this moment under the effect of air conditioner, indoor temperature can not produce big fluctuation, and the user is difficult to perceive the change of temperature.
Therefore, in this embodiment, when the outdoor return air temperature is less than or equal to the fifth temperature threshold and the indoor return air temperature is less than the sixth temperature threshold, the fresh air component is controlled to be turned off, that is, the step S304 is executed; when the outdoor return air temperature is less than or equal to the fifth temperature threshold value and the indoor return air temperature is greater than or equal to the sixth temperature threshold value, the fresh air assembly is controlled to be turned on, that is, step S305 is executed. Wherein the fifth temperature threshold is less than the sixth temperature threshold.
And S304, controlling the fresh air component to be closed.
S305, controlling the fresh air component to be started.
And S306, judging whether the outdoor return air temperature is less than or equal to a seventh temperature threshold value.
And when the outdoor return air temperature is determined to be greater than or equal to the sixth temperature threshold, judging the magnitude relation between the outdoor return air temperature and the seventh temperature threshold. When the outdoor return air temperature is greater than or equal to the sixth temperature threshold and less than or equal to the seventh temperature threshold, it indicates that the outdoor air temperature is relatively low, and at this time, it is necessary to continue to determine the indoor return air temperature, that is, step S307 is executed. And when the outdoor return air temperature is greater than the seventh temperature threshold value, the outdoor environment is relatively suitable, and at the moment, the indoor and outdoor temperature difference is relatively small, so that the fresh air component can be directly controlled to be started, namely the step S305 is executed.
And S307, judging whether the indoor return air temperature is less than an eighth temperature threshold value.
When the outdoor return air temperature is between the fifth temperature threshold and the seventh temperature threshold, the indoor return air temperature is compared with the eighth temperature threshold, and the size relation between the indoor return air temperature and the eighth temperature threshold can be determined. When the indoor return air temperature is lower than the eighth temperature threshold value, the fresh air assembly is started and is influenced by outdoor low-temperature air, so that the time length of indoor temperature rise can be prolonged, and the indoor return air temperature is contrary to the expectation of a user; when the indoor return air temperature is greater than or equal to the eighth temperature threshold value, because the indoor return air temperature is higher, the outdoor low-temperature air can quickly finish heat exchange with the indoor high-temperature air after entering the room, and at this time, under the action of the air conditioner, the indoor temperature cannot generate large fluctuation, and the user cannot easily perceive the temperature change.
Therefore, in this embodiment, when the outdoor return air temperature is greater than the fifth temperature threshold and the outdoor return air temperature is less than or equal to the seventh temperature threshold, if the indoor return air temperature is less than the eighth temperature threshold, the fresh air component is controlled to be closed, that is, the step S304 is executed; and if the indoor return air temperature is greater than or equal to the eighth temperature threshold value, controlling the fresh air assembly to be started, namely executing the step S305. Wherein the seventh temperature threshold is greater than the eighth temperature threshold.
Optionally, when the outdoor return air temperature is relatively high, it indicates that it is relatively comfortable outdoors, and therefore the influence of the air entering the room from the outside on the indoor air is relatively small, and therefore in this embodiment, the sixth temperature threshold may be selected to be smaller than the eighth temperature threshold, so as to update the indoor air by using the fresh air component earlier, and improve the comfort of the indoor environment.
In some embodiments, in order to improve the control accuracy, the temperature threshold of the indoor return air temperature of the air conditioner in different operation modes may also be determined according to the temperature value of the indoor return air temperature of the air conditioner in a preset time period. As shown in fig. 4, the method comprises the following steps:
s401, acquiring the maximum temperature value and the minimum temperature value of the indoor return air temperature of the air conditioner within a preset time.
The air conditioner can utilize temperature detection devices such as a temperature sensor to continuously or intermittently detect the indoor return air temperature in the operation process, so that the temperature value distribution condition of the indoor return air temperature in the preset time is obtained, and the maximum temperature value and the minimum temperature value are further determined.
S402, determining the temperature threshold of the indoor return air temperature of the air conditioner in the refrigeration mode according to the minimum temperature value.
After the minimum temperature value is determined, the temperature threshold value of the indoor return air temperature of the air conditioner in the refrigeration mode can be determined according to the minimum temperature value. Optionally, the temperature threshold of the indoor return air temperature in the refrigeration mode can be determined according to the minimum temperature value and the temperature compensation coefficient in the refrigeration mode; for example, the result of adding the minimum temperature value to the temperature compensation coefficient may be used as the temperature threshold of the return air temperature in the cooling mode.
And S403, determining the temperature threshold of the indoor return air temperature of the air conditioner in the heating mode according to the maximum temperature value.
After the maximum temperature value is determined, the temperature threshold value of the indoor return air temperature of the air conditioner in the heating mode can be determined according to the maximum temperature value. Optionally, the temperature threshold of the indoor return air temperature in the heating mode can be determined according to the maximum temperature value and the temperature compensation coefficient in the cooling mode; for example, the result of adding the maximum temperature value to the temperature compensation coefficient may be used as the temperature threshold of the indoor return air temperature in the heating mode.
In some embodiments, when the adjustment instruction of the set temperature of the air conditioner is received, the time length of the air conditioner operating in the target operation mode can be obtained again, so that the expectation of the user on the indoor temperature is matched with the control of the fresh air component, and the comfort performance of the air conditioner is improved.
To sum up, the technical solution in the embodiment of the present application at least has the following technical effects or advantages:
1. according to the target operation mode, the outdoor return air temperature and the indoor return air temperature, the fresh air assembly in the air conditioner is controlled to be opened or closed, so that the target operation mode, the outdoor return air temperature, the indoor return air temperature and the fresh air assembly are matched in operation state, the phenomenon that the comfort of the air conditioner is poor due to the fact that the fresh air assembly is opened is avoided, and the comfort performance of the air conditioner is improved.
2. Different control logics are constructed aiming at different operation modes of the air conditioner, and the control accuracy is improved.
3. According to the maximum temperature value and the minimum temperature value of the indoor return air temperature of the air conditioner in the preset time, the temperature threshold values of the indoor return air temperature in different operation modes are determined, and the control accuracy is improved.
