Based on the hardware structure, the invention provides a specific embodiment of the air conditioner control method.
Referring to fig. 3, a first embodiment of a method for controlling an air conditioner according to the present invention includes the following steps:
step S10: acquiring a first ambient temperature measured at an air return opening 112 of the air conditioner main body 100, a second ambient temperature measured at a control terminal 130 which is in the same indoor space and connected with the air conditioner main body 100, and a third ambient temperature measured at a display lamp panel 113;
in this embodiment, when the air conditioner main body 100 operates, air in the indoor environment enters the heat exchange air duct in the casing 111 from the air return opening 112, and after heat exchange, returns to the indoor environment from the air outlet, thereby implementing air circulation. Because the air circulates in the indoor environment, so that the temperatures are not completely the same at different locations indoors, the first ambient temperature represents the temperature value near the return air opening 112, closer to the temperature value of the air conditioner main body 100; the second ambient temperature represents a temperature value in the vicinity of the control terminal 130, which is closer to a current location of the user; the third ambient temperature represents the temperature value near the display lamp panel 113, which is between the first ambient temperature and the second ambient temperature, and is equivalent to the temperature value between the air conditioner main body 100 and the user.
Step S20: calculating the indoor environment temperature according to the first environment temperature, the second environment temperature, the third environment temperature and the preset corresponding relation between the first environment temperature, the second environment temperature, the third environment temperature and the indoor environment temperature;
in this embodiment, the control device is preset with a corresponding relationship between the first ambient temperature, the second ambient temperature, the third ambient temperature and the indoor ambient temperature, so that the control device can calculate the current indoor ambient temperature in real time according to the obtained first ambient temperature, the obtained second ambient temperature and the obtained third ambient temperature. Compared with the indoor environment temperature determined by a single detection point, the multipoint detection of the first environment temperature, the second environment temperature and the third environment temperature ensures that the indoor environment temperature determined by the three has more accuracy; in addition, the main measurement areas of the first ambient temperature, the second ambient temperature and the third ambient temperature are concentrated between the air conditioner main body 100 and the user, so that the interference of the temperature of the area far away from the user in the indoor environment on the determination of the indoor ambient temperature is reduced, and the temperature control method is more suitable for temperature regulation of the current position of the user.
Step S30: and controlling the air conditioner main body 100 to operate according to a preset operation mode corresponding to the indoor ambient temperature according to the indoor ambient temperature.
It is understood that when the accuracy of the indoor ambient temperature is improved, the adjustment of the operation mode of the air conditioner main body 100 with the indoor ambient temperature as a reference is more accurate. The indoor environment temperature and the preset operation mode have a one-to-one correspondence relationship, wherein the preset operation mode can be set to be different according to actual needs, for example, by comparing the indoor environment temperature with the set temperature, whether the current temperature needs to be increased or decreased can be determined, so that the air conditioner main body 100 is controlled to be correspondingly heated or cooled; further, by determining a specific difference between the indoor ambient temperature and the preset temperature, it may be correspondingly determined that a specific temperature value, a specific operation time, a specific wind speed, and the like of the air conditioner main body 100 that needs to be increased or decreased currently correspond to one of the preset operation modes, which is not described in detail herein.
In the technical scheme provided by the invention, the first environment temperature is equivalent to the temperature measured at the inlet of the indoor air circulation; the second ambient temperature corresponds to a temperature measured on the user periphery side; the third ambient temperature is a temperature measured at a location between the inlet of the indoor air circulation and the user. This application sets up a plurality of temperature check points, and a plurality of temperature check points distribute between air conditioner main part 100 and user for the indoor ambient temperature who determines jointly by first ambient temperature, second ambient temperature and third ambient temperature is more applicable to as the temperature reference of adjusting the current operational mode of air conditioner main part 100 in order to improve user's use comfort, and has more the accuracy.
Further, in the above embodiment, the correspondence relationship is:
T＝a×T1+b×T2+c×T3；
wherein T is the indoor ambient temperature; t1 is a first ambient temperature; t2 is the second ambient temperature; t3 is a third ambient temperature; a is a preset first environment temperature coefficient, and the value of a is 0.7-0.24; b is a preset second ambient temperature coefficient, and the value of b is 0.35-0.78; c is a preset third environment temperature coefficient, and the value of c is 0.2-0.4.
It can be understood that because the respective detection point positions and temperatures of the first ambient temperature, the second ambient temperature and the third ambient temperature are not uniform, the three temperatures are directly screened or averaged, so that calculation errors are easily caused, and the accuracy of the determined indoor ambient temperature is reduced. Therefore, in the embodiment, when the corresponding relationship is set, on one hand, a first environment temperature coefficient a is preset to correct the first environment temperature, a second environment temperature coefficient b is preset to correct the second environment temperature, and a third environment temperature coefficient c is preset to correct the third environment temperature, so that the finally determined indoor environment temperature is more in line with the actual situation; on the other hand, the determination of the preset correspondence makes the calculation of the indoor ambient temperature more accurate and rapid, and the control device can calculate the current indoor ambient temperature in real time, so that the switching of the operation mode of the air conditioner main body 100 is more efficient.
It can be understood that the preset first ambient temperature coefficient a, the preset second ambient temperature coefficient b, and the preset third ambient temperature coefficient c are equivalent to the ratio of the first ambient temperature, the second ambient temperature, and the third ambient temperature, and therefore the sum of the three should be 1. When any one of the preset first environment temperature coefficient a, the preset second environment temperature coefficient b and the preset third environment temperature coefficient c is higher, the corrected indoor environment temperature is higher directly; and vice versa. Because the second environment temperature is between the first environment temperature and the third environment temperature and is close to the intermediate value of the first environment temperature and the third environment temperature, namely is closer to the indoor environment temperature, the value range of the preset second environment temperature coefficient b is relatively larger, and the finally obtained indoor environment temperature is closer to the true value.
Further, in the above embodiment, when the air conditioner main body 100 is in the cooling mode, the preset first environment temperature coefficient a is 0.2, the preset second environment temperature coefficient b is 0.5, and the preset third environment temperature coefficient c is 0.3; and/or, when the air conditioner main body 100 is in the heating mode, the preset first environment temperature coefficient a is 0.1, the preset second environment temperature coefficient b is 0.6, and the preset third environment temperature coefficient c is 0.3. So set up, can carry out concrete correction to first ambient temperature, second ambient temperature and third ambient temperature to the different mode of air conditioner main part 100 for the calculated result is more accurate.
In addition, referring to fig. 4, in the second embodiment of the air conditioner control method according to the present invention, in the step S10: after acquiring the first ambient temperature measured at the air conditioner main body air return opening 112, the second ambient temperature measured at the control terminal 130, and the third ambient temperature measured at the display lamp panel 113, the method further includes:
step S41: controlling the air conditioner main body 100 to operate for a first preset time when the air conditioner main body 100 is in a heating mode;
step S42: acquiring a temperature difference value between the first ambient temperature and the second ambient temperature;
step S43: judging whether the temperature difference value between the first environment temperature and the second environment temperature is greater than or equal to a first preset threshold value or not;
step S44: outputting hot aggregate fault information when it is determined that a temperature difference between the first ambient temperature and the second ambient temperature is greater than or equal to a first preset threshold.
It can be understood that the temperature of each detection point is not stable when the air conditioner main body 100 is just started to operate; after the air conditioner main body 100 operates for a period of time and heat exchange adjustment is performed on the indoor environment, the temperature of each detection point tends to be stable, so that the temperature value of each detection point is more referential. The first preset time may be determined according to actual conditions, for example, in an embodiment, the first preset time may be determined to be about 25 minutes. After the air conditioner main body 100 operates for a first preset time, the control device starts to collect temperature values of the detection points.
Under the heating working mode, because the air conditioner main body 100's the interior machine air-out temperature is higher, and relative density is lower, if the air current organization of air conditioner main body 100 handles improperly, will make the higher gas of temperature gather in the upper region of indoor environment, and can't heat for the regional air in below of indoor environment, produce the heat and gather, lead to indoor environment heat transfer effect unbalance.
Generally, the return air opening 112 of the air conditioner main body 100 is provided at the upper end of the air conditioner main body 100 higher than the user is located, so that the first ambient temperature is approximately the air temperature of the upper area of the indoor environment; the control terminal 130 is disposed below the air conditioner main body 100 such that the second ambient temperature is substantially the air temperature of the lower area of the indoor environment. By calculating the temperature difference between the first ambient temperature and the second ambient temperature and comparing the temperature difference with a first preset threshold, it can be determined whether a thermal aggregation fault occurs currently. When the temperature difference is greater than or equal to the first preset threshold, it may be determined that the air with the higher temperature is focused above the indoor environment, and a heat aggregation phenomenon exists, and the control device 120 controls the air conditioner main body 100 to output heat aggregation fault information, so that the air conditioner main body 100 may take corresponding measures, such as adjusting an air outlet direction, according to the heat aggregation fault information.
Specifically, in the above embodiment, the first preset threshold is 5 to 9 ℃. It can be understood that if the first preset threshold is set to be larger, the air conditioner main body 100 is discovered after a serious heat aggregation fault occurs, which is likely to cause damage to the air conditioner main body 100; propagation, if the first preset threshold is set to be small, so that the air conditioner main body 100 is misinformed without the occurrence of the heat aggregation failure, resulting in unnecessary operations. In one embodiment, the first predetermined threshold is set to 6 ℃ to be more effective.
Referring to fig. 5, in a third embodiment of the air conditioner control method according to the present invention, in step S10: after acquiring the first ambient temperature measured at the air conditioner main body air return opening 112, the second ambient temperature measured at the control terminal 130, and the third ambient temperature measured at the display lamp panel 113, the method further includes:
step S50: controlling the air conditioner main body 100 to start up and operate for a second preset time;
step S511: when the air conditioner main body 100 is in a heating mode, acquiring a variable value of the first environment temperature and a variable value of the third environment temperature according to a preset period;
step S512: judging whether the variable value of the first environment temperature is smaller than or equal to a second preset threshold value or not, and whether the variable value of the third environment temperature is smaller than or equal to a third preset threshold value or not;
step S513: and outputting heating refrigerant lack fault information when the variable value of the first environment temperature is determined to be smaller than or equal to a second preset threshold value and the variable value of the third environment temperature is determined to be smaller than or equal to a third preset threshold value.
It can be understood that, similarly to the above, after the air conditioner main body 100 needs to be turned on for a certain time, the temperature of each detection point is stable and accurate. The second preset time can also be specifically set according to actual needs, for example, set to be about 15 minutes.
When the air conditioner main body 100 is in the heating operation mode, the variable value of the first ambient temperature and the variable value of the third ambient temperature are acquired according to a preset period. The specific numerical value of the preset period is also not limited, and in order to improve the accuracy of fault repair, the preset period may be set to be smaller, so that the frequency of temperature acquisition at each detection point is increased, but the operation load of the control device 120 is increased; conversely, the preset period may be set to be larger, so that the operation load of the control device 120 is reduced, but the frequency of temperature acquisition at each detection point is reduced, and the possibility of fault false reporting is increased. Therefore, the preset period may be specifically set to, for example, 5 seconds.
Whether the air conditioner main body 100 lacks a refrigerant can be detected by a temperature change of the indoor environment, and if the air conditioner main body 100 lacks a refrigerant, a heating effect of the air conditioner main body 100 does not meet a requirement. Since the hot air rises in the upper area of the indoor environment during heating, it is possible to determine whether or not the temperature change is abnormal by separately determining the first ambient temperature and the third ambient temperature, and thus it is possible to determine whether or not the heating refrigerant is in failure.
Referring to fig. 6, in a fourth embodiment of the air conditioner control method according to the present invention, in step S50: after controlling the air conditioner main body 100 to start up and operate for a second preset time, the method further includes:
step S521: when the air conditioner main body 100 is in a cooling mode, acquiring a variable value of the second environment temperature and a variable value of the third environment temperature according to a preset period;
step S522: judging whether the variable value of the second environment temperature is smaller than or equal to a fourth preset threshold value or not, and whether the variable value of the third environment temperature is smaller than or equal to a fifth preset threshold value or not;
step S523: and outputting refrigeration refrigerant shortage fault information when the variable value of the second environment temperature is determined to be smaller than or equal to a fourth preset threshold value and the variable value of the third environment temperature is determined to be smaller than or equal to a fifth preset threshold value.
As can be seen from the third embodiment, whether the air conditioner main body 100 lacks a refrigerant can be detected from a change in the temperature of the indoor environment, and if the air conditioner main body 100 lacks a refrigerant, the cooling effect of the air conditioner main body 100 similarly does not meet the demand. Since the cold air drops in the lower area of the indoor environment when the air conditioner main body 100 performs cooling, it is possible to determine whether or not the temperature change is abnormal by separately determining the second ambient temperature and the third ambient temperature, and thus it is possible to determine whether or not the cooling refrigerant is faulty.
In the above description, the variable values of the first ambient temperature, the second ambient temperature, and the third ambient temperature are absolute values. When the heating refrigerant fails or the cooling refrigerant fails, the air conditioner main body 100 may take corresponding measures to eliminate the failure, such as increasing the amount of refrigerant, and the like, which will not be described in detail herein.
In the third and fourth embodiments, the second preset threshold, the third preset threshold, the fourth preset threshold and the fifth preset threshold may be set to be different according to actual requirements; of course, the second preset threshold, the third preset threshold, the fourth preset threshold and the fifth preset threshold may also be set to be the same according to actual requirements, and for example, the second preset threshold, the third preset threshold, the fourth preset threshold and the fifth preset threshold are all set to be the same, and specific values are not limited, for example, all may be set to be 2-3 ℃, and may be specifically set to be 2 ℃.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
