Description
Technical Field
The invention relates to the field of air conditioner control, in particular to a control method of a kitchen air conditioner indoor unit, an air conditioner applying the method and a computer readable storage medium for realizing the method.
Background
With the rapid development of national economy, people pay more and more attention to the quality of life and the health and comfort of a home environment, so more and more people choose to install an air conditioner in a kitchen to build a comfortable and healthy cooking environment. Generally, an air conditioner has two operation modes of an indoor cycle in which indoor air is drawn into the air conditioner and the drawn air is cooled and then discharged to the indoor, and an outdoor cycle in which outdoor air is drawn into the air conditioner and cooled and then discharged to the indoor. Therefore, a fresh air fan and an indoor circulating fan are required to be arranged in the air conditioner, the fresh air fan is used for sucking outdoor air into the air conditioner, and the indoor circulating fan is used for sucking indoor air into the air conditioner.
Because the kitchen is the confined environment mostly, indoor air quality is relatively poor, if the work of indoor circulating fan of exclusive use, can lead to indoor air quality effectively to improve. If the fresh air fan is used independently, the temperature and the humidity of air pumped into the air conditioner are higher due to the fact that outdoor air is usually high in temperature and humidity in summer, and the air conditioner needs to increase refrigerating capacity to cool the outdoor air. Meanwhile, because the indoor circulating fan does not work, the cold energy of indoor air cannot be effectively utilized, and the energy is wasted.
Therefore, some existing air conditioners start a fresh air fan and an indoor circulating fan to work simultaneously, outdoor air and indoor air are sucked into the air conditioners simultaneously, on one hand, the quality of the indoor air is improved by utilizing the outdoor fresh air, and on the other hand, the refrigerating capacity of the air conditioners is reduced by effectively utilizing the refrigerating capacity of the indoor air. However, some existing air conditioners are provided with a fixed ratio of fresh air intake to indoor circulating intake, and cannot adjust the ratio of the fresh air intake to the indoor circulating intake according to the indoor air quality condition, and some air conditioners can automatically adjust the ratio of the fresh air intake to the indoor circulating intake according to the indoor air quality condition, but do not consider the rationality of the ratio of the fresh air intake to the indoor circulating intake, so that the refrigerating capacity of the air conditioner is still too high, and further the energy consumption of the air conditioner is too high.
Disclosure of Invention
A first object of the present invention is to provide a control method of an air conditioner that effectively improves indoor air quality and reduces energy consumption of the air conditioner.
A second object of the present invention is to provide an air conditioner implementing the control method of the air conditioner.
A third object of the present invention is to provide a computer-readable storage medium implementing the control method of the air conditioner described above.
In order to achieve the first purpose of the invention, the control method of the air conditioner provided by the invention comprises the steps of judging whether an indoor temperature value is higher than a preset temperature threshold value, and if so, simultaneously starting a fresh air fan and an indoor circulating fan; acquiring an indoor carbon dioxide concentration deviation value, judging whether the carbon dioxide concentration deviation value is greater than a preset deviation value or not, and if so, adjusting the ratio of fresh air intake to indoor circulating air intake; wherein, the ratio of the fresh air intake to the indoor circulating intake is in direct relation with the duration length of the deviation value of the carbon dioxide concentration being greater than the preset deviation value.
It is obvious by above-mentioned scheme, fresh air fan and indoor circulating fan are opened simultaneously to the air conditioner, when improving the indoor air quality through introducing outdoor air and indoor air conditioner simultaneously, can also effectively utilize the cold volume of indoor air, avoid the waste of energy. In addition, the air conditioner does not draw in a large amount of outdoor air at the beginning, but gradually increases the suction amount of the outdoor air along with the change of the indoor air quality, so that the indoor air quality is ensured, the cold energy of the indoor air can be effectively utilized to the maximum extent, the waste of the cold energy of the indoor air is avoided, and the energy consumption of the air is reduced.
One preferred scheme is that adjusting the ratio of fresh air intake to indoor circulating intake comprises: and if the carbon dioxide concentration deviation value is continuously greater than the preset deviation value, continuously adjusting the proportion of the fresh air intake and the indoor circulating air intake.
Therefore, when the carbon dioxide concentration of the indoor air is not reduced below the preset deviation value for a long time, the indoor air quality is not obviously improved, the indoor air quality is improved by continuously increasing the fresh air intake, the indoor air quality can be ensured to be good, and the indoor air quality can be continuously improved.
The further scheme is that adjusting the ratio of fresh air intake to indoor circulation intake includes: and taking the carbon dioxide concentration deviation value once every first preset time interval, and increasing the proportion of fresh air intake if the carbon dioxide concentration deviation value is continuously greater than the preset deviation value.
Therefore, the calculation of the carbon dioxide concentration deviation value is not continuously executed, but is executed at intervals, so that the energy consumption of the air conditioner can be prevented from being increased due to the continuous work of the carbon dioxide concentration sensor, and the situation that the indoor air quality is not timely improved due to the fact that the carbon dioxide concentration sensor does not work for a long time can be avoided.
The further proposal is that the ratio of the fresh air intake to the indoor circulating intake comprises more than two preset ratios; when confirming that carbon dioxide concentration deviation value is greater than preset deviation value, adjust the proportion of new trend intake and indoor circulation intake and include: and acquiring a preset ratio which is larger than the current ratio from the plurality of preset ratios as the adjusted ratio.
Therefore, the proportion of the fresh air intake can be quickly adjusted by presetting a plurality of different preset ratios.
Further, the step of obtaining a preset ratio larger than the current ratio from the plurality of preset ratios as the adjusted ratio comprises: and acquiring a preset ratio which is larger than the current ratio from a plurality of preset ratios in turn according to the sequence from small to large as the adjusted ratio.
Therefore, the proportion adjustment of the fresh air intake is carried out gradually, namely the proportion of the fresh air intake is increased gradually, and the proportion of the fresh air intake is not increased greatly at once, so that the waste of indoor air cooling capacity can be reduced.
In a further scheme, when the indoor temperature value is higher than the preset temperature threshold value, if the carbon dioxide concentration deviation value is not greater than the preset deviation value, the ratio of the current fresh air intake to the indoor circulating intake is maintained.
Therefore, the proportion of fresh air intake is not regulated under the condition that the indoor air quality is improved, and the waste of indoor air cold quantity is reduced.
According to a further scheme, when the indoor temperature value is higher than the preset temperature threshold value and the fresh air fan and the indoor circulating fan are started simultaneously, the ratio of the fresh air intake to the indoor circulating intake is a preset initial ratio. Preferably, the initial ratio is that the ratio of fresh air intake to indoor circulating intake is 1: 1.
therefore, the air conditioner works more reasonably, and can avoid overhigh energy consumption of the air conditioner while improving the indoor air quality.
If the indoor temperature value is not higher than the preset temperature threshold value, the first working mode and the second working mode are executed alternately; under the first operating mode, indoor circulating fan operates alone, and under the second operating mode, indoor circulating fan operates with the new trend fan simultaneously.
Therefore, even if the indoor temperature value is not too high, the air conditioner intermittently extracts outdoor fresh air, so that the quality of indoor air can be improved, and the influence on the indoor air quality caused by continuous circulation of only indoor air is avoided.
Further, the alternating between the first operating mode and the second operating mode comprises: after the first working mode is operated for a second preset time, the second working mode is entered; and after the second working mode runs for a third preset time, the first working mode is entered.
Therefore, the running time of the first working mode and the second working mode is fixed, so that certain working time of the two working modes can be ensured, and certain fresh air can be extracted from the outdoor space every time to improve the indoor air quality.
Further, the determining whether the indoor temperature value is higher than the preset temperature threshold includes: and acquiring a temperature value at the highest position of the indoor temperature, and judging whether the temperature value at the highest position of the indoor temperature is higher than a preset temperature threshold value or not.
Therefore, the air conditioner used in a kitchen is judged by taking the temperature value of the highest position of the indoor temperature as a judgment reference, whether the current cooking condition occurs or not can be accurately judged, the indoor air quality is adjusted more accurately, and the air conditioner is controlled more reasonably.
In a further scheme, the indoor carbon dioxide concentration deviation value is a difference value between a current indoor carbon dioxide concentration actual value and an indoor carbon dioxide concentration initial value.
Therefore, the initial carbon dioxide concentration of the indoor air is used as the reference for calculating the deviation value of the indoor carbon dioxide concentration, the change condition of the indoor air quality can be calculated more accurately, and the air conditioner can be controlled more accurately.
In order to achieve the second objective, the air conditioner provided by the present invention includes a circuit board, wherein the circuit board is provided with a processor and a memory, the memory stores a computer program, and the computer program implements the steps of the control method of the air conditioner when being executed by the processor.
To achieve the third object, the present invention provides a computer-readable storage medium having stored thereon a computer program, which when executed by a processor, implements the steps of the control method of the air conditioner described above.

Detailed Description
The control method of the air conditioner is applied to the air conditioner, preferably, the air conditioner is a kitchen air conditioner, and a fresh air fan and an indoor circulating fan are arranged in the air conditioner. The air conditioner is provided with a circuit board, the circuit board is provided with a processor and a memory, the memory stores a computer program, and the processor executes the computer program to realize the control method of the air conditioner.
The embodiment of the control method of the air conditioner comprises the following steps:
this embodiment mainly uses on kitchen air conditioner, for example this air conditioner is installed in the kitchen, and this air conditioner is provided with new trend fan and inner loop fan, and the new trend fan is used for the outdoor air of suction to the air conditioner in, and indoor loop fan then is used for the indoor air of suction to the air conditioner in. Preferably, new trend fan and inner loop fan can work alone, also can simultaneous working, if new trend fan works alone, then the air conditioner extracts outdoor air completely to indoor, if inner loop fan works alone, then the air conditioner extracts indoor air completely, if new trend fan and inner loop fan work simultaneously, then the air conditioner extracts outdoor air and indoor air simultaneously, discharges the air indoor after refrigerating. The embodiment mainly improves the quality of indoor air by controlling the work of the fresh air fan and the internal circulation fan, and reduces the energy consumption of the air conditioner to the maximum extent.
The operation of the present embodiment will be described with reference to fig. 1 and 2. First, step S1 is executed to acquire a temperature value at which the indoor temperature is highest. Since the air conditioner applying the embodiment is installed in a kitchen, when a user cooks in the kitchen, for example, when an open flame is generated, the temperature of the stove is the highest, so that the temperature value at the highest temperature in the kitchen is detected to judge whether the kitchen is in a cooking state currently, or whether the stove is in ignition at the current time.
Next, step S2 is executed to determine whether the temperature value at the highest indoor temperature is greater than the preset temperature threshold. In this embodiment, a temperature threshold needs to be preset, for example, 250 ℃, if the temperature threshold is exceeded, it is determined that the cooking state is currently in the cooking state, and step S3 is executed, otherwise, step S11 is executed.
If the temperature value at the highest position of the indoor temperature is confirmed to be larger than the preset temperature threshold value, namely the temperature value is currently in a cooking state, the concentration of carbon dioxide in the room is continuously increased, so that the quality of the air in the room is reduced, and outdoor fresh air needs to be introduced to improve the quality of the air in the room. Therefore, step S3 will turn on the fresh air fan and the indoor circulating fan at the same time. Preferably, in an initial stage when the fresh air fan and the indoor circulating fan are simultaneously turned on, the introduced fresh air intake and the indoor circulating air intake are a preset initial ratio, for example, the initial ratio is 1:1, that is, the introduced fresh air intake is equal to the indoor circulating air intake. In the assumption of unit time, the introduced fresh air intake is X, and the introduced indoor circulating air intake is Y, then at the initial stage that the fresh air fan and the indoor circulating fan are opened simultaneously, X: y is 1:1, i.e., X: the ratio of Y is 1. Of course, the initial ratio is not necessarily 1, so that other values, such as X: y is 1: and 5, the preset ratio is 0.2.
Then, after the operation is performed for a period of time in a state where the intake amount of the fresh air drawn in is equal to the indoor circulating intake amount, step S4 is performed, and it is determined whether the operation duration exceeds a first preset duration, for example, the first preset duration is 3 minutes, if the first preset duration is not reached, the waiting is continued, and if the operation duration exceeds the first preset duration, step S5 is performed, and the deviation value of the indoor carbon dioxide concentration is obtained. In this embodiment, the indoor carbon dioxide concentration deviation value is a difference between the current indoor carbon dioxide concentration actual value and the indoor carbon dioxide concentration initial value. Therefore, in the initial stage of the air conditioner starting operation, the initial value of the indoor carbon dioxide concentration needs to be detected, and the initial value is used as a reference for subsequently judging the indoor carbon dioxide concentration deviation value. Of course, the initial value of the indoor carbon dioxide concentration may also be the value of the indoor carbon dioxide concentration collected at the time when the determination result of step S2 is yes, that is, the value of the indoor carbon dioxide concentration at the time when the current cooking state is confirmed.
In step S5, the actual indoor carbon dioxide concentration value at the current time is obtained, and the difference between the actual indoor carbon dioxide concentration value and the initial indoor carbon dioxide concentration value is calculated and used as the indoor carbon dioxide concentration deviation value. Then, step S6 is executed, whether the deviation value of the indoor carbon dioxide concentration calculated at the current time is greater than the preset deviation value is determined, if yes, step S8 is executed, and if not, step S7 is executed.
If the determination result in the step S6 is negative, it indicates that the current indoor air quality is better or the air quality is improved, so step S7 is executed to maintain the current ratio of the fresh air intake, that is, the ratio of the fresh air intake to the indoor circulating air intake is not adjusted. If the judgment result in the step S6 is yes, indicating that the current indoor air quality is poor or the air quality is not improved, step S8 needs to be executed, and the ratio of the fresh air intake rate needs to be adjusted, for example, the ratio of the fresh air intake rate X to the indoor circulating intake rate Y is increased, and the intake rate of the fresh air is increased by adjusting the ratio, so as to improve the indoor air quality.
Preferably, a plurality of preset ratios are preset, the preset ratios are set from small to large, for example, the preset ratios can be 1:5, 1:4, 1:3, 1:2, 1:1, 2:1, 3:1, 4:1, 5:1 and the like from small to large, and the ratio of the fresh air intake amount X is correspondingly increased along with the increase of the ratios. Of course, the preset ratio can be other ratios, and the invention is not limited.
In step S8, a next preset ratio larger than the current ratio is obtained, and the obtained new preset ratio is used as the ratio of the adjusted fresh air intake X to the indoor circulating intake Y. For example, if the ratio of the current fresh air intake amount X to the indoor circulating intake amount Y is 1:1, and the next preset ratio larger than the current ratio is 2:1, step S8 is to obtain the preset ratio of 2:1 as the ratio of the adjusted fresh air intake amount X to the indoor circulating intake amount Y. At the moment, the ratio of the fresh air intake X to the indoor circulating air intake Y is adjusted by increasing the rotating speed of the fresh air fan and/or reducing the rotating speed of the indoor circulating fan.
Preferably, when the next preset ratio larger than the current ratio is obtained, the next preset ratio is obtained in sequence from small to large, for example, the ratio of the current fresh air intake X to the indoor circulating intake Y is 1:1, and there are a plurality of preset ratios larger than the current ratio, which are 2:1, 3:1, 4:1, 5:1, and the like, in this embodiment, the smallest one of the preset ratios is obtained as the adjusted ratio, that is, only 2:1 can be obtained as the adjusted ratio, and the other ratios larger than the preset ratio 2:1 cannot be obtained directly by skipping the preset ratio 2:1 as the adjusted ratio. For another example, if the ratio of the current fresh air intake amount X to the indoor circulating intake amount Y is 3:1, the obtained adjusted preset ratio is 4:1, instead of 5:1, and so on.
Then, step S9 is executed to determine whether the air conditioner stops operating, if not, the process returns to step S4, and if so, the process determines whether the operating time length exceeds a first preset time period under the condition of the ratio of the adjusted fresh air intake X to the indoor circulating intake Y, if so, the process continues to step S5, and obtains the indoor carbon dioxide concentration deviation value again, and determines the current indoor carbon dioxide concentration deviation value, if the current indoor carbon dioxide concentration deviation value is still higher than the preset deviation value, which indicates that the indoor air quality is still not obviously improved after the fresh air intake is increased, the process continues to step S8, and the ratio of the fresh air intake is increased again. It can be seen that, in the embodiment, the indoor carbon dioxide concentration deviation value is obtained once at intervals, and the proportion of the fresh air intake volume is gradually increased according to the duration that the indoor carbon dioxide concentration deviation value is greater than the preset deviation value, that is, the longer the duration that the indoor carbon dioxide concentration deviation value is greater than the preset deviation value, the larger the ratio of the fresh air intake volume to the indoor circulating air intake volume is, the larger the fresh air intake volume is, so as to achieve the purpose of improving the indoor air quality.
On the other hand, this embodiment is the proportion regulation to new trend intake is the gradual increase, does not jump a plurality of preset ratios and lets new trend intake increase by a wide margin suddenly, and consequently indoor circulation intake is the gradual decline, and the cold volume of indoor air will effectual being utilized, can not lead to the waste of the cold volume of indoor air to reduce the refrigerating output of air, the energy consumption of air conditioner also reduces.
If the judgment result in the step S2 is no, which indicates that the cooking state is not currently performed, the air conditioner performs a state of alternately executing a first working mode and a second working mode, where the first working mode is a mode of operating the indoor circulating fan alone, and the second working mode is a mode of operating the indoor circulating fan and the fresh air fan at the same time, and both the two working modes set an operating duration, and after each working mode operates for a certain period of time, the air conditioner switches to another working mode to operate, and thus the two working modes are alternately executed.
Specifically, step S11 is executed first, the indoor circulating fan is turned on separately, at this time, the air conditioner is in the first working mode, step S12 is executed, it is determined whether the running time length of the indoor circulating fan alone exceeds the second preset time length, if not, step S13 is executed, and the current working mode is maintained continuously, that is, the indoor circulating fan still works alone. And if the independent running time length of the indoor circulating fan exceeds a second preset time length, executing the step S14, and simultaneously starting the indoor circulating fan and the fresh air fan, namely, switching the air conditioner to a second working mode.
Then, step S15 is executed, it is determined whether the running time length in the second operating mode exceeds a third preset time length, if not, step S16 is executed, the current operating mode is continuously maintained, if yes, step S17 is executed, it is determined whether to stop running, if the air conditioner does not receive an instruction to stop running, step S11 is returned to be executed, the first operating mode is switched to, that is, the indoor circulating fan is independently started, and at this time, the fresh air fan stops running.
Optionally, the second preset time length is equal to the third preset time length, or the second preset time length is longer than the third preset time length, or the second preset time length is shorter than the third preset time length. This embodiment is through letting the air conditioner get into first mode and second mode in turn, also be every interval period from outdoor extraction fresh air, can avoid using indoor air circulation for a long time and lead to the problem of indoor air quality decline, in addition, because not in the culinary art stage, also be exactly there is not naked light, indoor air can not lead to the high temperature because of the existence of naked light, use the air source of indoor air as the air conditioner, can effectively utilize the cold volume of indoor air, reduce the problem that leads to the refrigerating output to increase because of extracting a large amount of outdoor air, be favorable to reducing the energy consumption of air conditioner.
It should be noted that, during the period when the air conditioner alternately executes the first working mode and the second working mode, the air conditioner detects the indoor temperature in real time, and judges whether the temperature value at the highest position of the indoor temperature is greater than the preset temperature threshold value in real time, if the temperature value at the highest position of the indoor temperature is determined to be greater than the preset temperature threshold value during the first working mode or the second working mode, the step S3 is immediately executed, the fresh air fan and the indoor circulating fan are simultaneously started, the indoor carbon dioxide concentration is detected, and whether the ratio of the fresh air intake volume to the indoor circulating air intake volume needs to be adjusted is determined according to the indoor carbon dioxide concentration condition.
Correspondingly, in the process of executing the steps S3 to S8, the indoor temperature is also detected in real time, whether the temperature value at the highest position of the indoor temperature is smaller than the preset temperature threshold value is judged in real time, and once the temperature value at the highest position of the indoor temperature is smaller than the preset temperature threshold value, it indicates that the user is not in the cooking state, the step S11 is executed, and the first working mode and the second working mode are alternately executed, so that the energy consumption of the air conditioner is reduced.
This embodiment is through the proportion of rational regulation new trend intake, gains the balance between improving indoor air quality and reducing the air conditioner energy consumption, makes the control of air conditioner more reasonable.
