The present invention aims to solve at least one of the technical problems existing in the prior art or related art.
To this end, a first aspect of the present invention provides a control method of an air conditioner.
The second aspect of the invention also provides a control device of the air conditioner.
The third aspect of the present invention also provides an air conditioner.
The fourth aspect of the present invention also provides an air conditioner.
The fifth aspect of the present invention also provides a readable storage medium.
In view of this, a first aspect of the present invention provides a control method of an air conditioner, the air conditioner including a compressor and a fresh air device for introducing outdoor fresh air, the control method including: judging whether to start the fresh air device under the condition of starting the mode without wind sensation; based on starting a fresh air device, determining an influence coefficient of the fresh air device on the environmental temperature of a room where the air conditioner is located; and controlling the frequency of the compressor and/or the rotating speed of the fresh air device according to the influence coefficient.
According to the control method of the air conditioner, provided by the invention, the air conditioner is provided with the compressor and the fresh air device, the fresh air device is communicated with the outdoor environment, and outdoor fresh air can be introduced into a room where the air conditioner is positioned from the outdoor environment so as to improve the freshness of indoor air, so that the indoor air is maintained at a comfortable level.
Under the condition that the air conditioner is opened in a non-wind sense mode, the air conditioner decomposes strong wind into non-wind sense soft wind, avoids the air outlet to directly blow the human body, and brings non-wind sense experience for users. The air conditioner product with the fresh air function can be used for starting fresh air at any time or sending a starting signal of a fresh air mode when a user perceives that indoor air is not fresh, and controlling the air conditioner to start the fresh air mode.
When the air conditioner is started in the air-feeling-free refrigerating mode, the refrigerating capacity is smaller than that of the conventional running mode, the influence of fresh air on the air-feeling-free refrigerating capacity is more remarkable, the air-feeling-free effect can be seriously influenced along with the continuous increase of fresh air quantity, and even a room cannot reach comfortable temperature for a long time. Therefore, after the air conditioner starts the fresh air device, the influence coefficient of the fresh air device on the environmental temperature of the room where the air conditioner is located is determined, and the frequency of the compressor and/or the rotating speed of the fresh air device are adjusted based on the influence coefficient.
According to the method and the device, under the condition that the air conditioner is opened in the windless mode and in the fresh air mode, the rotation speed of the fresh air device and/or the running frequency of the compressor are controlled according to the influence coefficient of the fresh air device on the ambient temperature of a room where the air conditioner is located, so that the influence of the fresh air device on the indoor ambient temperature caused by the fresh air introduced into a room is reduced, the interference of the opening fresh air device on the windless mode is effectively reduced, the indoor windless effect is not influenced, and the purpose of ensuring the fresh air effect is achieved.
According to the control method of the air conditioner provided by the invention, the control method can also have the following additional technical characteristics:
in the above technical solution, further, the step of determining an influence coefficient of the fresh air device on the environmental temperature of the room where the air conditioner is located includes: collecting the air outlet quantity and the air outlet temperature of the fresh air device; and determining the influence coefficient of the fresh air device on the environmental temperature of the room where the air conditioner is located according to the pre-stored corresponding relation between the air outlet quantity and the air outlet temperature and the influence coefficient and the collected air outlet quantity and air outlet temperature of the fresh air device.
In the technical scheme, a corresponding relation data table of the air outlet volume and the air outlet temperature of the fresh air device and the influence parameters of the air outlet temperature on the ambient temperature are prestored, and the collected influence parameters corresponding to the air outlet volume and the air outlet temperature of the current fresh air device can be inquired in a table look-up mode. Therefore, the influence degree of the opening of the fresh air device on the ambient temperature of the room can be determined, and based on the influence degree, the compressor and/or the fresh air device are adjusted, and the influence of the outdoor fresh air introduced on the air conditioner without the wind effect is reduced.
It should be noted that the air outlet temperature of the fresh air device includes the air inlet temperature or the air outlet temperature of the fresh air device.
In any of the above technical solutions, further, the step of controlling the frequency of the compressor according to the influence coefficient includes: and compensating the target temperature of the compressor based on the influence coefficient being greater than or equal to a first threshold value, and adjusting the frequency of the compressor according to the compensated target temperature.
In the technical scheme, when the influence coefficient is larger than or equal to the first threshold value, the influence on the ambient temperature in the room after the fresh air device is started is larger, and the frequency of the compressor needs to be controlled to be increased so as to improve the refrigerating capacity, so that the heat increased due to the introduction of the outdoor fresh air is counteracted. Specifically, the target temperature of the compressor is compensated, the target temperature is the calculated temperature, and the operation frequency of the compressor is calculated by using the calculated temperature.
By compensating the calculated temperature of the compressor, the operation frequency of the compressor is improved, so that refrigeration compensation is realized, the rise of the ambient temperature in a room caused by the introduction of fresh air is avoided, the lower temperature in the room can be kept, and fresh air exchange can be realized.
In any of the above technical solutions, further, the step of compensating for the target temperature of the compressor includes: determining a temperature compensation value according to the influence coefficient; and determining the target temperature according to the temperature compensation value and the set temperature of the air conditioner.
In the technical scheme, the corresponding relation between the influence coefficient and the temperature compensation value is prestored, and the temperature compensation value is determined according to the corresponding relation. Further, the temperature compensation value is used for compensating the target temperature of the compressor, specifically, the difference between the set temperature of the air conditioner (namely, the comfort temperature set by a user) and the temperature compensation value is taken as the target temperature, so that the purpose of improving the running frequency of the compressor is achieved, and refrigeration compensation in a fresh air mode is realized.
In any of the above technical solutions, further, according to the influence coefficient, the step of controlling the rotation speed of the fresh air device includes: based on the influence coefficient being greater than or equal to a first threshold value, acquiring the ambient temperature of the room where the air conditioner is located and the set temperature of the air conditioner; and controlling the rotating speed of the fresh air device according to the temperature difference value between the ambient temperature and the set temperature.
In the technical scheme, under the condition that the influence coefficient is larger than or equal to a first threshold value, the influence on the ambient temperature in a room after the fresh air device is started is larger, and the rotating speed of a fan of the fresh air device needs to be regulated so as to reduce the influence of the introduced outdoor fresh air on the windless effect.
Specifically, under the condition that the influence coefficient is greater than or equal to a first threshold value, the current rotating speed of the fresh air device is controlled by utilizing the temperature difference value between the ambient temperature and the set temperature (namely the comfort temperature set by a user), so that the fresh air quantity introduced into the room by the fresh air device is controlled, the introduction speed of the fresh air quantity is prevented from being too high, the indoor no-wind-sensation effect is seriously influenced, and the indoor no-wind-sensation effect is ensured while the oxygen content in the indoor air is supplemented.
In any of the above technical solutions, further, the step of controlling the rotation speed of the fresh air device according to the temperature difference between the ambient temperature and the set temperature includes: and maintaining the rotating speed of the fresh air device based on the temperature difference value being smaller than the second threshold value.
In the technical scheme, if the temperature difference between the current ambient temperature and the set temperature of the air conditioner is smaller than the second threshold value, the current ambient temperature is close to the set temperature, namely, the current ambient temperature can reach the set temperature quickly. At this time, after the fresh air device is opened, the influence of the outdoor air introduced through the fresh air device on the environment temperature approaching the set temperature is small, so that the current rotating speed is still maintained no matter the current rotating speed of the fresh air device, the indoor air quantity introduced by the current fresh air device is kept, and the purification efficiency of indoor air is ensured.
Wherein the preferred value of the above second threshold may be set to 1.5 ℃.
The current rotation speed of the fresh air device can be controlled according to the outdoor temperature. Specifically, if the temperature difference between the outdoor temperature and the ambient temperature of the room in which the air conditioner is located is large, the current rotation speed of the fresh air device is reduced, and if the temperature difference between the outdoor temperature and the ambient temperature of the room in which the air conditioner is located is small, the current rotation speed of the fresh air device is maintained.
In any of the above technical solutions, further, the step of controlling the rotation speed of the fresh air device according to the temperature difference between the ambient temperature and the set temperature includes: and maintaining the rotation speed of the fresh air device based on the temperature difference value being greater than or equal to the second threshold value and less than a third threshold value, and the target rotation speed of the fresh air device being less than or equal to the preset rotation speed, wherein the third threshold value is greater than the second threshold value.
In the technical scheme, if the temperature difference between the current ambient temperature and the set temperature of the air conditioner is greater than or equal to the second threshold value and less than the third threshold value, the temperature difference between the current ambient temperature and the set temperature is larger. When the fresh air device is started, if the target rotating speed of the fresh air device (namely, the rotating speed corresponding to the target wind gear set by a user) is smaller than or equal to the highest rotating speed of the low wind gear of the fresh air device (namely, the preset rotating speed), the target wind gear of the fresh air device is indicated to be the low wind gear, so that the outdoor air introduced by the fresh air device is less, the influence degree on the indoor environment is also less, and the fresh air device is controlled to maintain the current rotating speed to operate at the moment so as to ensure the efficiency of fresh air quantity introduced into the room by the fresh air device.
Wherein the preferred value of the third threshold may be set to 3 ℃.
It is to be understood that the wind level of the fresh air device can be divided into three levels of low wind level, medium wind level and high wind level, the preset rotating speed is the highest rotating speed of the fresh air device in the low wind level operation mode, whether the fresh air device is set to be the low wind level is judged, if the fresh air device is set to be the low wind level, the current rotating speed of the fresh air device is controlled, and therefore indoor fresh air changing is achieved, and meanwhile indoor no-wind effect is ensured.
In any of the above technical solutions, further, the step of controlling the rotation speed of the fresh air device according to the temperature difference between the ambient temperature and the set temperature includes: based on the fact that the temperature difference value is larger than or equal to the second threshold value and smaller than the third threshold value, and the target rotating speed of the fresh air device is larger than the preset rotating speed, the rotating speed change rate of the fresh air device is reduced; according to the reduced rotation speed change rate, controlling the rotation speed of the fresh air device to gradually increase; wherein the third threshold is greater than the second threshold.
In the technical scheme, if the temperature difference between the current ambient temperature and the set temperature of the air conditioner is greater than or equal to the second threshold value and less than the third threshold value, the current ambient temperature and the set temperature are larger in temperature difference. When the fresh air device is turned on, if the target rotation speed of the fresh air device is greater than the highest rotation speed (i.e. the preset rotation speed) of the low wind level of the fresh air device, the target wind level of the fresh air device is greater than the low wind level, in order to avoid the influence degree of the fresh air on the current environment temperature, the rotation speed change rate of the fresh air device is reduced, that is, if the rotation speed change rate corresponding to the target wind level of the fresh air device is the first change rate, the rotation speed of the fresh air device is controlled according to the rotation speed less than the first change rate, so that the air output of the fresh air device is gradually increased, instead of the rotation speed of the fresh air device in the related art being rapidly increased.
Through the mode, the running speed of the fresh air device is prevented from being increased too fast, the fresh air quantity introduced into the room is prevented from being too large, the influence of the fresh air quantity and the air outlet temperature on the indoor environment temperature is caused to be large, and the situation that the indoor wind-free effect is seriously influenced is further caused, so that the indoor wind-free effect is ensured when the fresh air is exchanged.
In any of the above technical solutions, further, the step of controlling the rotation speed of the fresh air device according to the temperature difference between the ambient temperature and the set temperature includes: controlling the rotation speed of the fresh air device to be reduced from the first rotation speed to the second rotation speed based on the fact that the temperature difference is larger than or equal to a third threshold value and the target rotation speed of the fresh air device is smaller than or equal to a preset rotation speed; the second rotating speed is the product of the first rotating speed and a correction coefficient, and the correction coefficient is more than 0.5 and less than 0.85.
In the technical scheme, if the temperature difference between the current ambient temperature and the set temperature of the air conditioner is greater than or equal to the third threshold value, the temperature difference between the current ambient temperature and the set temperature is large. When the fresh air device is started, if the target rotating speed of the fresh air device is smaller than or equal to the highest rotating speed of the low wind gear (namely, the preset rotating speed), the fresh air device is set to be in the low wind gear. In order to avoid the influence degree of fresh air on the current indoor temperature approaching the set temperature, the current rotating speed of the fresh air device is corrected, so that the current rotating speed can be reduced from the first rotating speed to the second rotating speed, the fresh air quantity introduced into the room by the fresh air device is reduced, the temperature difference between the current environment temperature and the set temperature is avoided to be large, the fresh air device is introduced into outdoor air, the influence degree on the indoor environment is large, the indoor no-wind effect is reduced, and the indoor no-wind effect is ensured when the fresh air is replaced indoors.
Wherein the second rotation speed is the product of the first rotation speed and a correction coefficient, the correction coefficient is greater than 0 and less than 1, and preferably the correction coefficient is greater than 0.5 and less than 0.85. The first rotating speed is the rotating speed corresponding to the low wind gear of the fresh air device, after the rotating speed is corrected, the fresh air device operates according to the corrected second rotating speed according to the temperature difference change between the ambient temperature and the set temperature, and the introduced fresh air quantity is reduced, so that the influence degree of the outdoor air introduced by the fresh air device on the indoor ambient temperature is reduced, and the indoor comfort level is ensured.
In any of the above technical solutions, further, the step of controlling the rotation speed of the fresh air device according to the temperature difference between the ambient temperature and the set temperature includes: controlling the rotation speed of the fresh air device to be reduced from the first rotation speed to the third rotation speed and reducing the rotation speed change rate of the fresh air device based on the fact that the temperature difference value is larger than or equal to a third threshold value and the target rotation speed of the fresh air device is larger than a preset rotation speed; according to the reduced rotation speed change rate, controlling the rotation speed of the fresh air device to gradually increase from the third rotation speed; the third rotation speed is the product of the first rotation speed and a correction coefficient, and the correction coefficient is more than 0.5 and less than 0.85.
In the technical scheme, if the temperature difference between the current ambient temperature and the set temperature of the air conditioner is greater than or equal to the third threshold value, the temperature difference between the current ambient temperature and the set temperature is large. When the fresh air device is started, if the target rotating speed of the fresh air device is larger than the highest rotating speed of the low wind level (namely the preset rotating speed), and the target wind level of the fresh air device is determined to be larger than the low wind level, the fresh air quantity introduced into the room of the fresh air device can be larger, and the indoor no-wind-sensation effect is damaged. Accordingly, the initial rotation speed of the fresh air device is controlled to be reduced from the first rotation speed to the third rotation speed, and the rotation speed change rate of the fresh air device is reduced, that is, if the rotation speed change rate corresponding to the target wind gear of the fresh air device is the first change rate, the fresh air device is controlled to gradually increase the rotation speed from the third rotation speed at a rate smaller than the first change rate, so that the air outlet volume of the fresh air device is gradually increased, instead of the rotation speed of the fresh air device in the related art being rapidly increased.
Wherein the third rotation speed is the product of the first rotation speed and a correction coefficient, the correction coefficient is greater than 0 and less than 1, and preferably the correction coefficient is greater than 0.5 and less than 0.85. The first rotating speed is the rotating speed corresponding to the low wind gear of the fresh air device, and after the rotating speed is corrected, the rotating speed of the fresh air device is gradually increased according to the corrected third rotating speed according to the temperature difference change between the ambient temperature and the set temperature.
Through the mode, the situation that the running speed of the fresh air device is increased too fast, the fresh air quantity introduced into the room is too large, and serious influence is caused on the indoor wind-free effect is avoided, and the indoor wind-free effect is ensured while the indoor fresh air exchange is realized.
According to a second aspect of the present invention, there is provided a control device of an air conditioner including a compressor and a fresh air device for introducing outdoor fresh air, the control device comprising: the judging module is used for judging whether the fresh air device is started or not under the condition that the wind sensing-free mode is started; the control module is used for: based on starting a fresh air device, determining an influence coefficient of the fresh air device on the environmental temperature of a room where the air conditioner is located; and controlling the frequency of the compressor and/or the rotating speed of the fresh air device according to the influence coefficient.
In the technical scheme, the air conditioner is provided with the compressor and the fresh air device, the fresh air device is communicated with the outdoor environment, and outdoor fresh air can be introduced into a room where the air conditioner is located from the outdoor environment so as to improve the freshness of indoor air, so that the indoor air is maintained at a comfortable level.
Under the condition that the air conditioner is opened in a non-wind sense mode, the air conditioner decomposes strong wind into non-wind sense soft wind, avoids the air outlet to directly blow the human body, and brings non-wind sense experience for users. The air conditioner product with the fresh air function can be started at any time by a user or can send a starting signal of a fresh air mode when the user perceives that the indoor air is not fresh, and after the receiving module receives the starting signal of the fresh air mode, the first control module responds to the received starting signal to control the air conditioner to start the fresh air mode.
When the air conditioner is started in the air-feeling-free refrigerating mode, the refrigerating capacity is smaller than that of the conventional running mode, the influence of fresh air on the air-feeling-free refrigerating capacity is more remarkable, the air-feeling-free effect can be seriously influenced along with the continuous increase of fresh air quantity, and even a room cannot reach comfortable temperature for a long time. Therefore, after the air conditioner starts the fresh air device, the influence coefficient of the fresh air device on the environmental temperature of the room where the air conditioner is located is determined, and the frequency of the compressor and/or the rotating speed of the fresh air device are adjusted based on the influence coefficient.
According to the method and the device, under the condition that the air conditioner is opened in the windless mode and in the fresh air mode, the rotation speed of the fresh air device and/or the running frequency of the compressor are controlled according to the influence coefficient of the fresh air device on the ambient temperature of a room where the air conditioner is located, so that the influence of the fresh air device on the indoor ambient temperature caused by the fresh air introduced into a room is reduced, the interference of the opening fresh air device on the windless mode is effectively reduced, the indoor windless effect is not influenced, and the purpose of ensuring the fresh air effect is achieved.

104, determining an influence coefficient of the fresh air device on the environmental temperature of the room where the air conditioner is located;
and 106, controlling the frequency of the compressor and/or controlling the rotating speed of the fresh air device according to the influence coefficient.
In this embodiment, the air conditioner is provided with a compressor and a fresh air device that communicates with an outdoor environment, and can introduce fresh air outdoors from the outdoor environment into a room in which the air conditioner is located to improve the freshness of the indoor air so as to maintain the indoor air at a comfortable level.
Under the condition that the air conditioner is opened in a non-wind sense mode, the air conditioner decomposes strong wind into non-wind sense soft wind, avoids the air outlet to directly blow the human body, and brings non-wind sense experience for users. The air conditioner product with the fresh air function can be used for starting fresh air at any time or sending a starting signal of a fresh air mode when a user perceives that indoor air is not fresh, and controlling the air conditioner to start the fresh air mode.
When the air conditioner is started in the air-feeling-free refrigerating mode, the refrigerating capacity is smaller than that of the conventional running mode, the influence of fresh air on the air-feeling-free refrigerating capacity is more remarkable, the air-feeling-free effect can be seriously influenced along with the continuous increase of fresh air quantity, and even a room cannot reach comfortable temperature for a long time. Therefore, after the air conditioner starts the fresh air device, the influence coefficient of the fresh air device on the environmental temperature of the room where the air conditioner is located is determined, and the frequency of the compressor and/or the rotating speed of the fresh air device are adjusted based on the influence coefficient.
According to the method and the device, under the condition that the air conditioner is opened in the windless mode and in the fresh air mode, the rotation speed of the fresh air device and/or the running frequency of the compressor are controlled according to the influence coefficient of the fresh air device on the ambient temperature of a room where the air conditioner is located, so that the influence of the fresh air device on the indoor ambient temperature caused by the fresh air introduced into a room is reduced, the interference of the opening fresh air device on the windless mode is effectively reduced, the indoor windless effect is not influenced, and the purpose of ensuring the fresh air effect is achieved.
In the above technical solution, further, the step of determining an influence coefficient of the fresh air device on the environmental temperature of the room where the air conditioner is located includes: collecting the air outlet quantity and the air outlet temperature of the fresh air device; and determining the influence coefficient of the fresh air device on the environmental temperature of the room where the air conditioner is located according to the pre-stored corresponding relation between the air outlet quantity and the air outlet temperature and the influence coefficient and the collected air outlet quantity and air outlet temperature of the fresh air device.
In the technical scheme, a corresponding relation data table of the air outlet volume and the air outlet temperature of the fresh air device and the influence parameters of the air outlet temperature on the ambient temperature are prestored, and the collected influence parameters corresponding to the air outlet volume and the air outlet temperature of the current fresh air device can be inquired in a table look-up mode. Therefore, the influence degree of the opening of the fresh air device on the ambient temperature of the room can be determined, and based on the influence degree, the compressor and/or the fresh air device are adjusted, and the influence of the outdoor fresh air introduced on the air conditioner without the wind effect is reduced.
It should be noted that the air outlet temperature of the fresh air device includes the air inlet temperature or the air outlet temperature of the fresh air device.
Example 2:
as shown in fig. 2, according to an embodiment of the present invention, there is provided a control method of an air conditioner, the method including:
and 206, compensating the target temperature of the compressor based on the influence coefficient being greater than or equal to the first threshold value, and adjusting the frequency of the compressor according to the compensated target temperature.
In this embodiment, in the case where the influence coefficient is greater than or equal to the first threshold value, indicating that the influence on the ambient temperature in the room after the fresh air device is turned on is large, it is necessary to control the frequency of the compressor to increase the cooling capacity, thereby counteracting the heat increased by the introduction of the outdoor fresh air. Specifically, the target temperature of the compressor is compensated, the target temperature is the calculated temperature, and the operation frequency of the compressor is calculated by using the calculated temperature.
By compensating the calculated temperature of the compressor, the operation frequency of the compressor is improved, so that refrigeration compensation is realized, the rise of the ambient temperature in a room caused by the introduction of fresh air is avoided, the lower temperature in the room can be kept, and fresh air exchange can be realized.
In any of the above technical solutions, further, the step of compensating for the target temperature of the compressor includes: determining a temperature compensation value according to the influence coefficient; and determining the target temperature according to the temperature compensation value and the set temperature of the air conditioner.
In the technical scheme, the corresponding relation between the influence coefficient and the temperature compensation value is prestored, and the temperature compensation value is determined according to the corresponding relation. Further, the temperature compensation value is used for compensating the target temperature of the compressor, specifically, the difference between the set temperature of the air conditioner (namely, the comfort temperature set by a user) and the temperature compensation value is taken as the target temperature, so that the purpose of improving the running frequency of the compressor is achieved, and refrigeration compensation in a fresh air mode is realized.
Further, the influence coefficient is proportional to the temperature compensation value. Specifically, the larger the influence coefficient is, the larger the temperature compensation value is; the smaller the influence coefficient, the smaller the temperature compensation value.
It should be noted that if the air output and the air output temperature of the fresh air device have no or little influence on the ambient temperature, the influence degree is determined to be zero, and then the temperature compensation value is zero, that is, the target temperature of the compressor is not compensated. By the mode, the operation frequency of the compressor is accurately controlled.
It should be noted that, in some embodiments, the step of determining the second temperature compensation value corresponding to the influence coefficient includes: determining that the second temperature compensation value is in a first compensation numerical range based on the influence coefficient being in a first preset range; determining that the second temperature compensation value is in a second compensation numerical range based on the influence coefficient being in a second preset range; determining that the second temperature compensation value is in a third compensation numerical range based on the influence coefficient being in a third preset range; wherein the values in the second preset range are greater than or equal to the values in the first preset range and less than or equal to the values in the third preset range, the first compensation value is preferably in the range of [0.5,1.5 ], the second compensation value is preferably in the range of [1.5,3 ], and the third compensation value is preferably in the range of [3, 5).
In other technical schemes, the influence coefficient may be a specific temperature value, and the temperature compensation value is equal to the specific temperature value corresponding to the influence coefficient. For example, if the fresh air mode is turned on, the air volume of the air outlet is 60 square, the air outlet temperature is 30 ℃, the influence temperature of the fresh air device on the indoor environment temperature is 0.5 ℃, if the air conditioner is in the refrigeration mode, the temperature compensation value is 0.5 ℃, and if the set temperature of the air conditioner is 26 ℃, the calculated temperature for calculating the operation frequency of the compressor is 25.5 ℃.
In addition, it is noted that the degree of influence of the air output volume and the air output temperature of the fresh air device on the environmental temperature in the room is also related to the volume of the room where the air conditioner is located, however, since the model of the air conditioner is determined according to the volume of the room where the air conditioner is located, the corresponding relationship can be set according to the model of the air conditioner. Of course, considering that the user can match the model of the air conditioner with the volume of the room, the volume of the room can be synthesized when the influence degree of the wind volume and the wind outlet temperature on the environment temperature is determined, so that the accuracy of the determination is improved.
In some embodiments, the refrigerating capacity of the compressor can be compensated according to the influence coefficient, which specifically includes: determining the required cold energy for processing the heat load of the fresh air device according to the air outlet quantity, the air outlet temperature and the air outlet rheumatism degree of the fresh air device; the refrigerating capacity of the compressor is compensated according to the initial refrigerating capacity and the required refrigerating capacity.
Through the mode, the purpose of improving the running frequency of the compressor is achieved, the interference of opening the fresh air device to the windless mode is effectively reduced, and therefore the purpose of not affecting indoor windless effect and guaranteeing fresh air effect is achieved.
Example 3:
as shown in fig. 3, according to an embodiment of the present invention, there is provided a control method of an air conditioner, the method including:
and 308, controlling the rotating speed of the fresh air device according to the temperature difference between the ambient temperature and the set temperature.
In this embodiment, when the influence coefficient is greater than or equal to the first threshold, it indicates that the influence on the ambient temperature in the room is greater after the fresh air device is turned on, and the rotation speed of the fan of the fresh air device needs to be adjusted to reduce the influence of the introduced outdoor fresh air on the windless effect.
Specifically, under the condition that the influence coefficient is greater than or equal to a first threshold value, the current rotating speed of the fresh air device is controlled by utilizing the temperature difference value between the ambient temperature and the set temperature (namely the comfort temperature set by a user), so that the fresh air quantity introduced into the room by the fresh air device is controlled, the introduction speed of the fresh air quantity is prevented from being too high, the indoor no-wind-sensation effect is seriously influenced, and the indoor no-wind-sensation effect is ensured while the oxygen content in the indoor air is supplemented.
In some embodiments, after the rotation speed control of the fresh air device is completed, the influence coefficient of the current fresh air device on the environmental temperature of the room where the air conditioner is located can be detected, so that the operation frequency of the compressor is further controlled according to the above.
Example 4:
in this embodiment, the step of controlling the rotation speed of the fresh air device according to the temperature difference between the ambient temperature and the set temperature includes: and maintaining the rotating speed of the fresh air device based on the temperature difference value being smaller than the second threshold value.
In the technical scheme, if the temperature difference between the current ambient temperature and the set temperature of the air conditioner is smaller than the second threshold value, the current ambient temperature is close to the set temperature, namely, the current ambient temperature can reach the set temperature quickly. At this time, after the fresh air device is opened, the influence of the outdoor air introduced through the fresh air device on the environment temperature approaching the set temperature is small, so that the current rotating speed is still maintained no matter the current rotating speed of the fresh air device, the indoor air quantity introduced by the current fresh air device is kept, and the purification efficiency of indoor air is ensured.
Wherein the preferred value of the above second threshold may be set to 1.5 ℃.
The current rotation speed of the fresh air device can be controlled according to the outdoor temperature. Specifically, if the temperature difference between the outdoor temperature and the ambient temperature of the room in which the air conditioner is located is large, the current rotation speed of the fresh air device is reduced, and if the temperature difference between the outdoor temperature and the ambient temperature of the room in which the air conditioner is located is small, the current rotation speed of the fresh air device is maintained.
Example 5:
in this embodiment, the step of controlling the rotation speed of the fresh air device according to the temperature difference between the ambient temperature and the set temperature includes: and maintaining the rotation speed of the fresh air device based on the temperature difference value being greater than or equal to the second threshold value and less than a third threshold value, and the target rotation speed of the fresh air device being less than or equal to the preset rotation speed, wherein the third threshold value is greater than the second threshold value.
In the technical scheme, if the temperature difference between the current ambient temperature and the set temperature of the air conditioner is greater than or equal to the second threshold value and less than the third threshold value, the temperature difference between the current ambient temperature and the set temperature is larger. When the fresh air device is started, if the target rotating speed of the fresh air device (namely, the rotating speed corresponding to the target wind gear set by a user) is smaller than or equal to the highest rotating speed of the low wind gear of the fresh air device (namely, the preset rotating speed), the target wind gear of the fresh air device is indicated to be the low wind gear, so that the outdoor air introduced by the fresh air device is less, the influence degree on the indoor environment is also less, and the fresh air device is controlled to maintain the current rotating speed to operate at the moment so as to ensure the efficiency of fresh air quantity introduced into the room by the fresh air device.
Wherein the preferred value of the third threshold may be set to 3 ℃.
It is to be understood that the wind level of the fresh air device can be divided into three levels of low wind level, medium wind level and high wind level, the preset rotating speed is the highest rotating speed of the fresh air device in the low wind level operation mode, whether the fresh air device is set to be the low wind level is judged, if the fresh air device is set to be the low wind level, the current rotating speed of the fresh air device is controlled, and therefore indoor fresh air changing is achieved, and meanwhile indoor no-wind effect is ensured.
Example 6:
in this embodiment, the step of controlling the rotation speed of the fresh air device according to the temperature difference between the ambient temperature and the set temperature includes: based on the fact that the temperature difference value is larger than or equal to the second threshold value and smaller than the third threshold value, and the target rotating speed of the fresh air device is larger than the preset rotating speed, the rotating speed change rate of the fresh air device is reduced; according to the reduced rotation speed change rate, controlling the rotation speed of the fresh air device to gradually increase; wherein the third threshold is greater than the second threshold.
In the technical scheme, if the temperature difference between the current ambient temperature and the set temperature of the air conditioner is greater than or equal to the second threshold value and less than the third threshold value, the current ambient temperature and the set temperature are larger in temperature difference. When the fresh air device is turned on, if the target rotation speed of the fresh air device is greater than the highest rotation speed (i.e. the preset rotation speed) of the low wind level of the fresh air device, the target wind level of the fresh air device is greater than the low wind level, in order to avoid the influence degree of the fresh air on the current environment temperature, the rotation speed change rate of the fresh air device is reduced, that is, if the rotation speed change rate corresponding to the target wind level of the fresh air device is the first change rate, the rotation speed of the fresh air device is controlled according to the rotation speed less than the first change rate, so that the air output of the fresh air device is gradually increased, instead of the rotation speed of the fresh air device in the related art being rapidly increased.
Through the mode, the running speed of the fresh air device is prevented from being increased too fast, the fresh air quantity introduced into the room is prevented from being too large, the influence of the fresh air quantity and the air outlet temperature on the indoor environment temperature is caused to be large, and the situation that the indoor wind-free effect is seriously influenced is further caused, so that the indoor wind-free effect is ensured when the fresh air is exchanged.
Example 7:
in this embodiment, the step of controlling the rotation speed of the fresh air device according to the temperature difference between the ambient temperature and the set temperature includes: controlling the rotation speed of the fresh air device to be reduced from the first rotation speed to the second rotation speed based on the fact that the temperature difference is larger than or equal to a third threshold value and the target rotation speed of the fresh air device is smaller than or equal to a preset rotation speed; the second rotating speed is the product of the first rotating speed and a correction coefficient, and the correction coefficient is more than 0.5 and less than 0.85.
In the technical scheme, if the temperature difference between the current ambient temperature and the set temperature of the air conditioner is greater than or equal to the third threshold value, the temperature difference between the current ambient temperature and the set temperature is large. When the fresh air device is started, if the target rotating speed of the fresh air device is smaller than or equal to the highest rotating speed of the low wind gear (namely, the preset rotating speed), the fresh air device is set to be in the low wind gear. In order to avoid the influence degree of fresh air on the current indoor temperature approaching the set temperature, the current rotating speed of the fresh air device is corrected, so that the current rotating speed can be reduced from the first rotating speed to the second rotating speed, the fresh air quantity introduced into the room by the fresh air device is reduced, the temperature difference between the current environment temperature and the set temperature is avoided to be large, the fresh air device is introduced into outdoor air, the influence degree on the indoor environment is large, the indoor no-wind effect is reduced, and the indoor no-wind effect is ensured when the fresh air is replaced indoors.
Wherein the second rotation speed is the product of the first rotation speed and a correction coefficient, the correction coefficient is greater than 0 and less than 1, and preferably the correction coefficient is greater than 0.5 and less than 0.85. The first rotating speed is the rotating speed corresponding to the low wind gear of the fresh air device, after the rotating speed is corrected, the fresh air device operates according to the corrected second rotating speed according to the temperature difference change between the ambient temperature and the set temperature, and the introduced fresh air quantity is reduced, so that the influence degree of the outdoor air introduced by the fresh air device on the indoor ambient temperature is reduced, and the indoor comfort level is ensured.
Example 8:
in this embodiment, the step of controlling the rotation speed of the fresh air device according to the temperature difference between the ambient temperature and the set temperature includes: controlling the rotation speed of the fresh air device to be reduced from the first rotation speed to the third rotation speed and reducing the rotation speed change rate of the fresh air device based on the fact that the temperature difference value is larger than or equal to a third threshold value and the target rotation speed of the fresh air device is larger than a preset rotation speed; according to the reduced rotation speed change rate, controlling the rotation speed of the fresh air device to gradually increase from the third rotation speed; the third rotation speed is the product of the first rotation speed and a correction coefficient, and the correction coefficient is more than 0.5 and less than 0.85.
In the technical scheme, if the temperature difference between the current ambient temperature and the set temperature of the air conditioner is greater than or equal to the third threshold value, the temperature difference between the current ambient temperature and the set temperature is large. When the fresh air device is started, if the target rotating speed of the fresh air device is larger than the highest rotating speed of the low wind level (namely the preset rotating speed), and the target wind level of the fresh air device is determined to be larger than the low wind level, the fresh air quantity introduced into the room of the fresh air device can be larger, and the indoor no-wind-sensation effect is damaged. Accordingly, the initial rotation speed of the fresh air device is controlled to be reduced from the first rotation speed to the third rotation speed, and the rotation speed change rate of the fresh air device is reduced, that is, if the rotation speed change rate corresponding to the target wind gear of the fresh air device is the first change rate, the fresh air device is controlled to gradually increase the rotation speed from the third rotation speed at a rate smaller than the first change rate, so that the air outlet volume of the fresh air device is gradually increased, instead of the rotation speed of the fresh air device in the related art being rapidly increased.
Wherein the third rotation speed is the product of the first rotation speed and a correction coefficient, the correction coefficient is greater than 0 and less than 1, and preferably the correction coefficient is greater than 0.5 and less than 0.85. The first rotating speed is the rotating speed corresponding to the low wind gear of the fresh air device, and after the rotating speed is corrected, the rotating speed of the fresh air device is gradually increased according to the corrected third rotating speed according to the temperature difference change between the ambient temperature and the set temperature.
Through the mode, the situation that the running speed of the fresh air device is increased too fast, the fresh air quantity introduced into the room is too large, and serious influence is caused on the indoor wind-free effect is avoided, and the indoor wind-free effect is ensured while the indoor fresh air exchange is realized.

In this embodiment, after the air conditioner is turned on without a wind sensing function, the cold output required by the air conditioner without a wind sensing is determined according to the difference between the room ambient temperature and the set temperature (i.e. the comfort temperature set by the user), if the temperature difference is in the first preset range, when the fresh air is turned on, the air outlet volume (fresh air volume) and the air outlet temperature (fresh air temperature) are obtained, the influence degree of the air outlet volume on the room temperature is calculated, and the temperature compensation of the same degree is performed on the air conditioner target temperature (calculated temperature). For example, if the influence of the fresh air on the room temperature is 0.5 ℃ after the fresh air is opened is small, the fresh air module is not corrected at this time, the calculated air temperature is negatively compensated by 0.5 ℃ (the air conditioner is set at 26 ℃ and the temperature for calculating the compressor frequency is 25.5 ℃), so that the fresh air can be opened, the cooling capacity without wind sense is improved, and the comfortable effect of the room is ensured.
Further, if the temperature difference is in a second preset range, after the fresh air is started, judging that the fresh air fan sets a wind gear, if the fresh air is low, acquiring the air outlet quantity and the air outlet temperature, calculating the influence degree of the air outlet quantity and the air outlet temperature on the room temperature, and performing equal-degree temperature compensation on the air conditioner target temperature. If other wind baffles are set, the low wind is operated by default, the influence degree of the wind output and the wind output temperature on the room temperature is calculated, the temperature compensation of the same degree is carried out on the air-conditioning target temperature, and then the temperature is gradually increased to stroke or high wind according to the temperature difference change of the room temperature and the set temperature.
Further, if the temperature difference is in a third preset range, after the fresh air is started, if the fresh air is low, the coefficient K correction is carried out on the actual running rotating speed of the fresh air, the influence degree of the air outlet quantity and the air outlet temperature on the room temperature is calculated, and the temperature compensation of the same degree is carried out on the air conditioner target temperature. If other wind fenders are set, the default operation low wind is multiplied by a correction coefficient K, the influence degree of the wind output and the wind output temperature on the room temperature is calculated, the temperature compensation of the same degree is carried out on the calculated temperature of the air conditioner, and then the temperature is gradually increased to stroke or high wind according to the temperature difference change of the room temperature and the set temperature.

In the related art, the fresh air of many factories is basically ignored due to small fresh air quantity, but the fresh air quantity is gradually increased along with the increase of the acceptance of the fresh air function, so that the influence of the fresh air on the indoor comfort cannot be ignored, and experimental tests show that the influence of the fresh air on the room comfort is reduced by 1.0 ℃ when the fresh air is 60-square, the influence of the fresh air is reduced by about 1 to 2 ℃ when the normal temperature is reduced by 1.7 meters or less, the refrigeration capacity of the machine model without the wind sense function is small compared with that of the normal refrigeration mode when the machine model without the wind sense is started, the influence of the fresh air on the refrigeration capacity without the wind sense is more prominent, the effect of the temperature reduction without the wind sense is seriously influenced along with the continuous increase of the fresh air quantity, and even the room cannot reach the comfort temperature for a long time. Through the embodiment of the invention, when the air conditioner is started to have no wind sense function, after a user starts the fresh air function, the wind sense effect can be ensured, and fresh air can be obtained.
