Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above 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 invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
At present, the conditions of the heating mode operation are as follows: when the T ambient temperature is less than the T set temperature and 3 ℃, starting a compressor; when the T ambient temperature > T set temperature +5 ℃, the compressor is stopped. Experimental tests were performed according to this control logic and the relevant data are summarized in table 1 below:
TABLE 1
Taking the setting temperature of 25 ℃ as an example: when the machine is stopped when the temperature reaches a temperature point for the first time, the actual environment temperature of the detected room is 28.32 ℃, and the detection temperature of the environment temperature sensing bulb is 29.7 ℃. According to logic judgment, when the room temperature is reduced to 25+ 3-28 ℃ and the machine is stopped for 3 minutes, the compressor is started to enter the heating operation. In the actual situation, after the machine is stopped for 3 minutes, the actual environment temperature of the room is reduced to 26.44 ℃, but the temperature of the environment temperature sensing bulb is increased to 31.16 ℃, so that the control system judges erroneously and the compressor is not started for heating operation. After the machine is stopped for 9 minutes, the actual environment temperature of the room is reduced to 24.13 ℃, and the detection temperature of the environment temperature sensing bulb is reduced to 27.8 ℃, the compressor is started again, and the heating operation is carried out. At the moment, the actual temperature of the room is lower than the set temperature, and the downtime is long, so that the practicability and the comfort of use are influenced. After the air conditioner is started again to operate, the fan starts to operate, air heated by the evaporator around the environment temperature sensing bulb is taken away under the influence of air flow and is replaced by newly sucked environment air, and the sampling value of the temperature sensing bulb can be rapidly reduced and is close to the real environment temperature.
From the above data, it can be preliminarily concluded that: if after the heating operation reaches the temperature point and the machine is shut down, the sampling value of the environmental temperature sensing bulb is continuously increased, and meanwhile, after the compressor is started and the fan enters the heating operation again, the sampling value of the environmental temperature sensing bulb is rapidly reduced, so that the situation that after the heating operation reaches the temperature point and the machine is shut down, the sampling value of the environmental temperature sensing bulb is influenced by the heat of the evaporator can be judged, and the sampling value during the machine is not a real environmental temperature value.
Fig. 1 is a schematic method diagram of an embodiment of an air conditioner control method provided by the present invention.
As shown in fig. 1, according to an embodiment of the present invention, the air conditioner control method includes at least step S110, step S120, step S130, and step S140.
Step S110, when the air conditioner is in heating operation, when the temperature detection device detects that the ambient temperature meets a preset shutdown condition, controlling the compressor of the air conditioner to be shut down, and acquiring a first ambient temperature detected by the temperature detection device when the compressor is shut down.
The preset shutdown condition specifically comprises that the ambient temperature is greater than the sum of the set temperature and a third preset temperature value. For example, the third preset temperature value is 5 ℃, i.e., TAmbient temperature＞TSet temperature+5 ℃. The temperature detection device may be, for example, an environmental bulb near an indoor heat exchanger. When the temperature detection device detects that the ambient temperature meets the preset stop condition, the compressor of the air conditioner is controlled to stop, and meanwhile, the ambient temperature value T1 detected by the temperature detection device when the compressor stops is obtained.
And step S120, after the compressor is controlled to stop for a first preset time, the compressor is controlled to be started again, and a second ambient temperature detected by the temperature detection device when the compressor is started again is obtained.
For example, after the compressor is controlled to stop for 3min, the compressor is controlled to be turned on again, and the ambient temperature value T2 at the time of the compressor turning on again detected by the temperature detection device is acquired.
And step S130, when the compressor is controlled to be turned on again for a second preset time, acquiring a third ambient temperature detected by the temperature detection device.
For example, after controlling the compressor to start for 2min, the ambient temperature value T3 detected by the temperature detection device is obtained.
Step S140, determining a control operation on the air conditioner after the temperature detection device detects that the ambient temperature satisfies the shutdown condition next time according to whether the first, second, and third ambient temperatures satisfy a preset condition.
The preset conditions may specifically include: the first preset condition is as follows: whether the difference between the second ambient temperature T2 and the first ambient temperature T1 is greater than a first preset temperature value; and, a second preset condition: whether the difference between the second ambient temperature T2 and the third ambient temperature T3 is greater than a second preset temperature value. The first preset temperature value and the second preset temperature value may be equal or unequal. For example, the first preset temperature value is 2 ℃, the second preset temperature value is 2 ℃, and the first preset condition is as follows: T2-T1 > 2 ℃; the second preset condition is as follows: T2-T3 > 2 ℃.
Specifically, if the first, second and third ambient temperatures satisfy the first preset condition and the second preset condition, the compressor is controlled to be restarted after being stopped for a first preset time after the temperature detection device detects that the ambient temperature satisfies the stop condition next time; if the first, second and third ambient temperatures do not satisfy the first preset condition and/or the second preset condition, after the temperature detection device detects that the ambient temperature satisfies the shutdown condition next time, the compressor is controlled to be shut down for a first preset time, and then whether the compressor is restarted is determined according to whether the detected ambient temperature satisfies the preset startup condition.
More specifically, the first ambient temperature T1 is the ambient temperature when the temperature detection device detects that the ambient temperature satisfies the shutdown condition and the compressor is shutdown, and the second ambient temperature T2 is the ambient temperature when the compressor is turned on after the compressor is shutdown for the first preset time, so if the difference between the second ambient temperature T2 and the first ambient temperature T1 is greater than the first preset temperature value, for example, T2-T1 > 2 ℃, it indicates that the temperature detection device (for example, the ambient temperature sensing bulb) still rises after the compressor is shutdown, and the detected value may be affected by the heat of the indoor heat exchanger. The third ambient temperature T3 is the third ambient temperature detected by the temperature detection device obtained when the compressor is controlled to be turned on again for the second preset time; therefore, if the difference between the second ambient temperature T2 and the third ambient temperature T3 is greater than a second predetermined temperature value, for example, T2-T3 > 2 ℃, it indicates that after the compressor is turned on again, the fan is turned on and the air flows, so that the temperature detected by the temperature detecting device (for example, the ambient temperature bulb) is rapidly decreased. If T2-T3 > 2 ℃ is not satisfied, this indicates that the ambient temperature is indeed at a higher value. Therefore, whether the ambient temperature detection value of the temperature detection device is affected by the heat of the indoor heat exchanger is determined according to whether the first, second and third ambient temperatures satisfy the first preset condition and the second preset condition.
If the first preset condition and the second preset condition are both met, the detection value of the temperature detection device is subjected to the indoor heat exchangerThe compressor is controlled to be restarted after being stopped for a first preset time after the temperature detection device detects that the environmental temperature meets the stop condition next time; if any one of the first preset condition and the second preset condition is not met or the first preset condition and the second preset condition are not met, the detection value of the temperature detection device is not affected by the heat of the indoor heat exchanger, after the temperature detection device detects that the environmental temperature meets the shutdown condition next time, the compressor is controlled to shut down for a first preset time, and then whether the environmental temperature detected by the temperature detection device meets the preset startup condition is judged, and if the startup condition is met, the compressor is controlled to start up. The starting-up condition may specifically include that the ambient temperature is less than the sum of the set temperature and a fourth preset temperature value. The third preset temperature value is greater than the fourth preset temperature value. For example, the fourth preset temperature value is 3 ℃, i.e., the startup condition is TAmbient temperature<TSet temperature+3℃。
Alternatively, whether the preset condition is satisfied may be identified by a preset flag, that is, whether the first preset condition and the second preset condition are satisfied is identified by a preset flag. For example, if a first preset condition is satisfied, the flag bit a is 1, otherwise, the flag bit a is 0, if a second preset condition is satisfied, the flag bit B is 1, otherwise, the flag bit B is 0.
For example, after the first ambient temperature and the second ambient temperature are obtained, it may be determined whether the first ambient temperature and the second ambient temperature satisfy a first preset condition, for example, T2-T1 > 2 ℃, if so, the flag bit a is set to 1, otherwise, the flag bit a is set to 0; when the third ambient temperature is obtained, it is determined whether the second ambient temperature and the third ambient temperature satisfy a second preset condition, for example, T2-T3 > 2 ℃, if so, the flag B is assigned to 1, otherwise, the flag B is assigned to 0, and if a is 1 and B is 1, the compressor is turned on after the next shutdown for a first preset time (for example, 3 minutes) when the shutdown condition is satisfied. If A, B is not equal to 1 at the same time, the next shutdown with the shutdown condition is followed by meeting the shutdown time for the first preset time (e.g., meeting the shutdown time for the first preset time)3 minutes) and boot conditions (e.g., T)Ambient temperature<TSet temperatureAt +3 deg.C, the compressor can be restarted.
For clearly explaining the technical solution of the present invention, the following describes an execution flow of the air conditioner control method provided by the present invention with a specific embodiment.
Fig. 2 is a schematic method diagram of an embodiment of an air conditioner control method according to the present invention. The embodiment shown in fig. 2 includes steps S201 to S208.
Step S201, after the compressor is stopped when the set temperature point is reached in the air conditioner heating operation process, recording the environmental temperature T1 at the stop time of the compressor.
In step S202, after the shutdown is performed for 3 minutes (first preset time), the compressor is turned on again, and the ambient temperature T2 at the time of turning on the compressor is recorded, and at the same time, step S203 is performed.
Step S203, determining whether T2-T1 > 2 ℃ is satisfied, if yes, assigning a flag bit a to 1, otherwise, assigning a flag bit a to 0.
In step S204, after the compressor is turned on again for 2 minutes (the second preset time), the environmental temperature T3 collected at this time is recorded, and step S205 is executed.
And step S205, judging whether T2-T3 is more than 2 ℃, if so, assigning the flag bit B to be 1, and otherwise, assigning the flag bit B to be 0.
In step S206, it is determined whether T2-T1 > 2 ℃ and T2-T3 > 2 ℃, that is, flag a is 1 and flag B is 1, if yes, step S207 is executed, and if no, step S208 is executed.
In step S207, if the flag a is equal to 1 and the flag B is equal to 1, it is determined that the detection value of the environmental bulb is affected by heat of the evaporator (indoor heat exchanger), and after the shutdown is performed at the next temperature point, it is not determined whether the difference between the environmental temperature and the set temperature is satisfied, and the computer is restarted after the shutdown time reaches 3 minutes (first preset time).
In step S208, if a is not satisfied, or B is not satisfied, it is determined that the ambient temperature sensing bulb sampling is not affected by the heat of the evaporator (indoor heat exchanger), and when the engine is restarted after the next shutdown when reaching a temperature point, the engine needs to be stoppedThe machine time reaches a first preset time, and TAmbient temperature＜TSet temperatureAt +3 deg.C, the compressor is turned on again.
Fig. 3 is a block diagram of an embodiment of an air conditioning control apparatus according to the present invention. As shown in fig. 3, the air conditioning control apparatus 100 includes a control unit 110 and an acquisition unit 120.
The control unit 110 is configured to, when the air conditioner is in heating operation, control a compressor of the air conditioner to stop when the temperature detection device detects that the ambient temperature meets a preset stop condition; the acquiring unit 120 is configured to acquire a first ambient temperature detected by the temperature detecting device when the compressor is stopped; the control unit 110 is further configured to: controlling the compressor to be started again after controlling the compressor to be stopped for a first preset time; the obtaining unit 120 is further configured to: acquiring a second ambient temperature detected by the temperature detection device when the compressor is restarted; the obtaining unit 120 is further configured to: when the control unit 110 controls the compressor to be started again for a second preset time, acquiring a third ambient temperature detected by the temperature detection device; the control unit 110 is further configured to: and determining the control operation of the air conditioner after the temperature detection device detects that the ambient temperature meets the shutdown condition next time according to whether the first, second and third ambient temperatures meet preset conditions.
When the air conditioner is in heating operation, when the temperature detection device detects that the ambient temperature meets a preset shutdown condition, the control unit 110 controls the compressor of the air conditioner to shutdown, and obtains a first ambient temperature detected by the temperature detection device when the compressor is shutdown.
The preset shutdown condition specifically comprises that the ambient temperature is greater than the sum of the set temperature and a third preset temperature value. For example, the third preset temperature value is 5 ℃, i.e., TAmbient temperature＞TSet temperature+5 ℃. The temperature detection device may be, for example, an environmental bulb near an indoor heat exchanger. When the temperature detecting device detects that the ambient temperature meets the preset stop condition, the control unit 110 controls the compressor of the air conditioner to stop, and simultaneously obtains the temperature detection when the compressor stopsAnd measuring the ambient temperature value T1 detected by the device.
The control unit 110 controls the compressor to be turned on again after controlling the compressor to be stopped for a first preset time; the obtaining unit 120 obtains the second ambient temperature detected by the temperature detecting device when the compressor is turned back on.
For example, the control unit 110 controls the compressor to be turned on again after controlling the compressor to be stopped for 3min, and the obtaining unit 120 obtains the ambient temperature value T2 at the time of the compressor being turned on again, which is detected by the temperature detecting device.
The control unit 110 controls the compressor to be turned on again for a second preset time, and the obtaining unit 120 obtains a third ambient temperature detected by the temperature detecting device.
For example, after the control unit 110 controls the compressor to start for 2min, the obtaining unit 120 obtains the ambient temperature value T3 detected by the temperature detecting device.
The control unit 110 determines the control operation of the air conditioner after the temperature detection device detects that the ambient temperature satisfies the shutdown condition next time according to whether the first, second, and third ambient temperatures satisfy preset conditions. The preset conditions may specifically include: the first preset condition is as follows: whether the difference between the second ambient temperature T2 and the first ambient temperature T1 is greater than a first preset temperature value; and, a second preset condition: whether the difference between the second ambient temperature T2 and the third ambient temperature T3 is greater than a second preset temperature value. The first preset temperature value and the second preset temperature value may be equal or unequal. For example, the first preset temperature value is 2 ℃, the second preset temperature value is 2 ℃, and the first preset condition is as follows: T2-T1 > 2 ℃; the second preset condition is as follows: T2-T3 > 2 ℃.
Specifically, if the first, second and third ambient temperatures satisfy the first preset condition and the second preset condition, the compressor is controlled to be restarted after being stopped for a first preset time after the temperature detection device detects that the ambient temperature satisfies the stop condition next time; if the first, second and third ambient temperatures do not satisfy the first preset condition and/or the second preset condition, after the temperature detection device detects that the ambient temperature satisfies the shutdown condition next time, the compressor is controlled to be shut down for a first preset time, and then whether the compressor is restarted is determined according to whether the detected ambient temperature satisfies the preset startup condition.
More specifically, the first ambient temperature T1 is the ambient temperature when the temperature detection device detects that the ambient temperature satisfies the shutdown condition and the compressor is shutdown, and the second ambient temperature T2 is the ambient temperature when the compressor is turned on after the compressor is shutdown for the first preset time, so if the difference between the second ambient temperature T2 and the first ambient temperature T1 is greater than the first preset temperature value, for example, T2-T1 > 2 ℃, it indicates that the temperature detection device (for example, the ambient temperature sensing bulb) still rises after the compressor is shutdown, and the detected value may be affected by the heat of the indoor heat exchanger. The third ambient temperature T3 is the third ambient temperature detected by the temperature detection device obtained when the compressor is controlled to be turned on again for the second preset time; therefore, if the difference between the second ambient temperature T2 and the third ambient temperature T3 is greater than a second predetermined temperature value, for example, T2-T3 > 2 ℃, it indicates that after the compressor is turned on again, the fan is turned on and the air flows, so that the temperature detected by the temperature detecting device (for example, the ambient temperature bulb) is rapidly decreased. If T2-T3 > 2 ℃ is not satisfied, this indicates that the ambient temperature is indeed at a higher value. Therefore, whether the ambient temperature detection value of the temperature detection device is influenced by the heat of the indoor heat exchanger is determined according to whether the first, second and third ambient temperatures meet the first preset condition and the second preset condition.
If the first preset condition and the second preset condition are both met, the detection value of the temperature detection device is influenced by the heat of the indoor heat exchanger, and the compressor is controlled to be restarted after being stopped for a first preset time after the temperature detection device detects that the environmental temperature meets the stop condition next time; if any one of the first preset condition and the second preset condition is not met or the first preset condition and the second preset condition are not met, the detection value of the temperature detection device is not influenced by the heat of the indoor heat exchanger, and after the temperature detection device detects that the environmental temperature meets the shutdown condition next time, the temperature detection device controls the shutdown conditionAnd judging whether the ambient temperature detected by the temperature detection device meets a preset starting condition or not after the compressor is stopped for a first preset time, and controlling the compressor to start if the ambient temperature meets the starting condition. The starting-up condition may specifically include that the ambient temperature is less than the sum of the set temperature and a fourth preset temperature value. The third preset temperature value is greater than the fourth preset temperature value. For example, the fourth preset temperature value is 3 ℃, i.e., the startup condition is TAmbient temperature<TSet temperature+3℃。
Alternatively, whether the preset condition is satisfied may be identified by a preset flag, that is, whether the first preset condition and the second preset condition are satisfied is identified by a preset flag. For example, if a first preset condition is satisfied, the flag bit a is 1, otherwise, the flag bit a is 0, if a second preset condition is satisfied, the flag bit B is 1, otherwise, the flag bit B is 0.
For example, after the first ambient temperature and the second ambient temperature are obtained, it may be determined whether the first ambient temperature and the second ambient temperature satisfy a first preset condition, for example, T2-T1 > 2 ℃, if so, the flag bit a is set to 1, otherwise, the flag bit a is set to 0; when the third ambient temperature is obtained, it is determined whether the second ambient temperature and the third ambient temperature satisfy a second preset condition, for example, T2-T3 > 2 ℃, if so, the flag B is assigned to 1, otherwise, the flag B is assigned to 0, and if a is 1 and B is 1, the compressor is turned on after the next shutdown for a first preset time (for example, 3 minutes) when the shutdown condition is satisfied. If A, B is not equal to 1 at the same time, the next shutdown with the shutdown condition satisfied needs to satisfy both the shutdown time as the first preset time (e.g. 3 minutes) and the startup condition (e.g. T)Ambient temperature<TSet temperatureAt +3 deg.C, the compressor can be restarted.
