In view of this, according to one aspect of the present invention, there is provided a control method of an air conditioner including a compressor, a fan, 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 refrigeration mode; 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 adjusting the frequency of the compressor and/or adjusting the rotating speed of the fan according to the influence coefficient.
In the technical scheme, the air conditioner is provided with a fan, a compressor and a fresh air device, wherein the fresh air device is communicated with an outdoor environment, and can introduce outdoor fresh air from the outdoor environment into a room where the air conditioner is located.
When the user has a refrigeration requirement, a signal for starting the refrigeration mode is sent out. And the air conditioner receives an opening signal of the refrigeration mode and controls the air conditioner to enter the refrigeration mode.
Further, whether the air conditioner starts a fresh air mode is judged, and after the fresh air mode is started, a fresh air device of the air conditioner starts to work so as to introduce fresh air into a room and improve air quality. In addition, the fresh air is introduced, and the outdoor fresh air temperature is higher than the current environment temperature in the room, or the outdoor environment humidity is higher than the indoor environment humidity, so that the current refrigeration effect can be influenced. Therefore, after the fresh air mode is started, 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 fan is adjusted based on the influence coefficient.
Through the mode, under the condition that the refrigerating mode is started and the fresh air mode is started, according to the influence coefficient of the fresh air device on the ambient temperature, the frequency of the compressor or the rotating speed of the fan is adjusted so as to increase the refrigerating capacity and the air quantity, thereby reducing the influence of the fresh air on the ambient temperature of a room, and ensuring the comfort of the room temperature while changing the fresh air of the room.
The control method of the air conditioner according to the invention can also have the following additional technical characteristics:
in the above technical solution, the step of determining the 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 fan can be adjusted to improve the refrigerating capacity and the air quantity, so that the heat which is increased due to the introduction of the outdoor fresh air is counteracted, and the comfort of the ambient temperature in the room is ensured.
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, the step of adjusting the frequency of the compressor according to the influence coefficient includes: 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; or, based on the influence coefficient being greater than or equal to the first threshold, compensating the refrigerating capacity of the compressor, and adjusting the frequency of the compressor according to the compensated refrigerating capacity.
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. Methods of increasing the operating frequency of a compressor are specifically defined.
One is to compensate for a target temperature of the compressor, which is a calculated temperature, and calculate an operating frequency of the compressor using the calculated temperature. By compensating the calculated temperature of the compressor, an increase in the operating frequency of the compressor is achieved.
It should be noted that the compensation for the target temperature of the compressor may be 0 compensation, that is, not compensation. Calculating the operating frequency of the compressor according to the compensated target temperature under the condition of compensation; the operating frequency of the compressor is calculated according to the original target temperature without compensation.
Another case is to compensate the refrigerating capacity (i.e., refrigerating capacity) of the compressor and increase the target refrigerating capacity of the compressor, thereby realizing an increase in the operating frequency of the compressor.
The purpose of improving the operation frequency of the compressor is achieved through the two modes, so that refrigeration compensation is achieved, 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 achieved.
In any of the above technical solutions, the step of compensating for a target temperature of the compressor includes: and determining the target temperature according to the set temperature of the air conditioner and the pre-stored first temperature compensation value.
In this embodiment, a first temperature compensation value for compensating for the target temperature of the compressor is stored in advance. After the influence coefficient is judged to be greater than or equal to the first threshold value, the first temperature compensation value can be directly utilized to compensate the target temperature of the compressor, specifically, the difference value between the set temperature of the air conditioner (namely, the comfort temperature set by a user) and the first 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 some embodiments, the first compensation value is 0 if compensation is not required.
In any of the above technical solutions, the step of compensating for a target temperature of the compressor includes: determining a second temperature compensation value according to the influence coefficient; and determining the target temperature according to the second temperature compensation value and the set temperature of the air conditioner.
In the technical scheme, the corresponding relation between the influence coefficient and the second temperature compensation value is prestored, and the second temperature compensation value is determined according to the corresponding relation. Further, the second temperature compensation value is utilized to compensate the target temperature of the compressor, specifically, the difference value between the set temperature of the air conditioner and the second 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 solutions, the larger the influence coefficient, the larger the second temperature compensation value, wherein the influence coefficient is zero, and the second temperature compensation value is zero.
In the technical scheme, the influence coefficient of the air outlet volume and the air outlet temperature on the ambient temperature in the room is in direct proportion to the second temperature compensation value. Specifically, the larger the influence coefficient is, the larger the second temperature compensation value is, the more the operation frequency of the compressor is increased. The smaller the influence coefficient, the smaller the second temperature compensation value, and the smaller the operation frequency of the compressor increases.
By the mode, the operation frequency of the compressor is accurately controlled, the reliability of refrigeration compensation is improved, and the refrigeration effect is improved.
It should be noted that if the air output and the air output temperature have no or little influence on the ambient temperature, the influence coefficient is determined to be zero, and then the second temperature compensation value is zero, that is, the target temperature of the compressor is not compensated.
In any of the above technical solutions, the step of compensating the refrigerating capacity of the compressor includes: determining the initial refrigerating capacity of the compressor according to the set temperature of the air conditioner; 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; and determining the refrigerating capacity of the compressor according to the initial refrigerating capacity and the required refrigerating capacity.
In the technical scheme, the initial refrigerating capacity of the compressor is determined according to the set temperature of the air conditioner and the ambient temperature. And detecting the air outlet quantity, the air outlet temperature and the air outlet humidity of the fresh air device, and calculating the heat load of the fresh air device according to the air outlet quantity, the air outlet temperature and the air outlet humidity. Further, the required cooling capacity for counteracting the heat load of the fresh air device is determined, and the required cooling capacity is compensated to the initial cooling capacity of the compressor, so that the operation frequency of the compressor is improved.
Through the mode, the purpose of improving the running frequency of the compressor is achieved, so that refrigeration compensation is achieved, 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 achieved.
In any of the above solutions, in the process of adjusting the frequency of the compressor, the method further includes: the air guide angle of the air guide assembly of the air conditioner is increased.
In this technical scheme, the air outlet of air conditioner is provided with the wind-guiding subassembly, when increasing the frequency of compressor, can also adjust the air output of the air outlet of air conditioner through adjusting the wind-guiding angle of wind-guiding subassembly, and then realizes better reaching the effect that will introduce new trend and increase the heat and offset.
In any of the above technical solutions, the step of increasing the air guiding angle of the air guiding assembly of the air conditioner includes: based on the required cooling capacity being greater than or equal to a second threshold value, increasing the air guide angle of an air guide assembly of the air conditioner; wherein the preferred value of the second threshold is greater than or equal to 1000W.
In the technical scheme, under the condition that the required cooling capacity is larger than or equal to a second threshold value, the air guide angle of the air guide assembly is increased, so that the air output of the air outlet of the air conditioner is increased, the effect of counteracting the heat increased by introducing fresh air is better achieved, and the influence of the fresh air on the room environment temperature is reduced.
In any of the above technical solutions, according to the influence coefficient, the step of adjusting the rotation speed of the fan includes: determining a target rotating speed of the fan according to the influence coefficient based on the influence coefficient being greater than or equal to a first threshold value; and controlling the fan to operate according to the target rotating speed.
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 is larger after the fresh air device is started, and the rotation speed of the fan needs to be controlled to be increased so as to improve the air quantity, so that the heat increased due to the introduction of the outdoor fresh air is counteracted. Specifically, a rotation speed compensation value for compensating the rotation speed of the fan is determined according to the influence coefficient, wherein the influence coefficient and the rotation speed compensation value can be pre-stored with a corresponding relation. Further, the sum of the rotation speed compensation value and the initial rotation speed of the fan is used as a target rotation speed, so that the purpose of increasing the rotation speed of the fan is achieved, and refrigeration compensation in a fresh air mode is realized.
In any of the above solutions, the step of adjusting the frequency of the compressor and/or adjusting the rotation speed of the fan includes: and adjusting the frequency of the compressor and/or the rotating speed of the fan until the ambient temperature is less than or equal to the set temperature of the air conditioner.
In the technical scheme, the process of increasing the frequency of the compressor or the rotating speed of the fan to perform refrigeration compensation is not necessarily performed once, but the current parameter operation can be maintained as long as the refrigeration compensation is performed when the influence coefficient is judged to be greater than or equal to the first threshold value in the whole working process of starting the refrigeration mode and starting the fresh air mode until the ambient temperature is less than or equal to the set temperature.

When the user has a refrigeration requirement, a signal for starting the refrigeration mode is sent out. And the air conditioner receives an opening signal of the refrigeration mode and controls the air conditioner to enter the refrigeration mode.
Further, whether the air conditioner starts a fresh air mode is judged, and after the fresh air mode is started, a fresh air device of the air conditioner starts to work so as to introduce fresh air into a room and improve air quality. In addition, the fresh air is introduced, and the outdoor fresh air temperature is higher than the current environment temperature in the room, or the outdoor environment humidity is higher than the indoor environment humidity, so that the current refrigeration effect can be influenced.

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 fan can be adjusted to improve the refrigerating capacity and the air quantity, so that the heat which is increased due to the introduction of the outdoor fresh air is counteracted, and the comfort of the ambient temperature in the room is ensured.
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 two
In this embodiment, the step of adjusting 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, an increase in the operating frequency of the compressor is achieved.
It should be noted that the compensation for the target temperature of the compressor may be 0 compensation, that is, not compensation. Calculating the operating frequency of the compressor according to the compensated target temperature under the condition of compensation; the operating frequency of the compressor is calculated according to the original target temperature without compensation.
Through the mode, the purpose of improving the running frequency of the compressor is achieved, so that refrigeration compensation is achieved, 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 achieved.
Example III
In this embodiment, the step of compensating for the target temperature of the compressor includes: and determining the target temperature according to the set temperature of the air conditioner and the pre-stored first temperature compensation value.
In this embodiment, a first temperature compensation value for compensating for the target temperature of the compressor is stored in advance. After the influence coefficient is judged to be greater than or equal to the first threshold value, the first temperature compensation value can be directly utilized to compensate the target temperature of the compressor, specifically, the difference value between the set temperature of the air conditioner (namely, the comfort temperature set by a user) and the first 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 some embodiments, the first compensation value is 0 if compensation is not required.
It should be noted that the pre-stored first temperature compensation value may relate to the ambient temperature and the set temperature, for example, a correspondence relationship between the first temperature compensation value and a difference between the set temperature and the ambient temperature is pre-stored, and for example, when the difference between the set temperature and the ambient temperature is 2 ℃, the first temperature compensation value is 2 ℃. By limiting the first temperature compensation value to be related to the ambient temperature and the set temperature, a more accurate compensation can be achieved to improve the comfort of the room temperature.
Example IV

Further, the second temperature compensation value is utilized to compensate the target temperature of the compressor, specifically, the difference value between the set temperature of the air conditioner and the second 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.
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 value in the second preset range is larger than or equal to the value in the first preset range and smaller than or equal to the value in the third preset range, the first compensation value range is [0.5,1.5 ], the second compensation value range is [1.5,3 ], and the third compensation value range is [3, 5).
In other technical solutions, the influence coefficient may be a specific temperature value, and the second temperature compensation value is equal to the specific temperature value corresponding to the influence coefficient. For example, if the air outlet volume is 60 square, the air outlet temperature is 30 ℃, the influence coefficient of the air outlet device on the ambient temperature is 0.5 ℃, the second 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 influence coefficient on the environmental temperature in the room is also related to the volume of the room in which the air conditioner is located, but since the model of the air conditioner is determined according to the volume of the room in which the air conditioner is located, the above correspondence relationship may 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 coefficient 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 any of the above solutions, the larger the influence coefficient, the larger the second temperature compensation value, wherein the influence coefficient is zero, and the second temperature compensation value is zero.
In the technical scheme, the influence coefficient of the air outlet volume and the air outlet temperature on the ambient temperature in the room is in direct proportion to the second temperature compensation value. Specifically, the larger the influence coefficient is, the larger the second temperature compensation value is, the more the operation frequency of the compressor is increased. The smaller the influence coefficient, the smaller the second temperature compensation value, and the smaller the operation frequency of the compressor increases.
By the mode, the operation frequency of the compressor is accurately controlled, the reliability of refrigeration compensation is improved, and the refrigeration effect is improved.
It should be noted that if the air output and the air output temperature have no or little influence on the ambient temperature, the influence coefficient is determined to be zero, and then the second temperature compensation value is zero, that is, the target temperature of the compressor is not compensated.

It should be noted that the required cooling capacity may be equal to or slightly greater than the heat load of the fresh air device, that is, the difference between the required cooling capacity and the heat load of the fresh air device is less than a preset threshold, so as to avoid the problems of insufficient cancellation and excessive cooling capacity.
In addition, specifically, the cooling capacity of the compressor is compensated according to the required cooling capacity based on the case where the required cooling capacity is greater than or equal to a third threshold value, wherein the third threshold value is greater than 0 and less than or equal to 300W, that is, the operation frequency of the compressor is adjusted when the required cooling capacity is greater than a certain value, and is not adjusted when the required cooling capacity is small.
