Background
At present, two adjacent rooms can be set to the same set temperature, so that the temperature in the two rooms can be adjusted to the set temperature, and thus, a user has better problem experience in the reciprocating process of the two rooms. The two adjacent rooms may be two adjacent offices in an office scene, or two adjacent rooms in a home scene. In addition, the user has the need for the indoor temperature and the freshness of the indoor air, and the fresh air device can supply the outdoor air into a room to provide fresh air for the room so as to improve the freshness of the air in the room.
In some prior arts, an indoor temperature sensor may be used to detect an indoor temperature, an outdoor temperature sensor may be used to detect an outdoor temperature, and a temperature difference between the indoor temperature and the outdoor temperature is calculated, and the rotation speed of the air inlet fan is controlled according to the temperature difference, for example, when the temperature difference is greater than or equal to a first threshold, the air inlet fan is controlled to operate at full speed; when the temperature difference is smaller than a first threshold and larger than or equal to a second threshold, controlling the air inlet machine to operate at a medium speed; when the temperature difference is smaller than a second threshold and larger than zero, controlling the air inlet fan to operate at a low speed; and when the temperature difference is equal to zero, closing the air inlet machine. Therefore, the energy consumption of the air conditioner can be reduced in the process of adjusting the indoor temperature by using the air conditioner.
In the process of implementing the embodiment of the present application, it is found that at least the following problems exist in the related art:
air flow usually exists between two adjacent rooms with the same set temperature, for example, two rooms separated by a partition in an office scene or two rooms communicated with each other through a door in a home scene, and under the condition that temperature adjustment and fresh air introduction are simultaneously performed on the two rooms, if the temperature and the air freshness of each room are independently adjusted, because the fresh air is simultaneously provided for the two rooms, under the influence of factors such as room area, room sealing degree and fresh air rate, the air flow easily occurs between the two rooms, and further, the heat exchange quantity of the two rooms is improved. In this way, when the temperatures of the two rooms are about to reach the set temperature, the temperatures of the two rooms are not easily stabilized at the set temperature quickly due to the influence of the heat exchange amounts of the two rooms.
It is noted that the information disclosed in the above background section is only for enhancement of understanding of the background of the present application and therefore may include information that does not constitute prior art that is already known to a person of ordinary skill in the art.

During the execution of the control method, a temperature adjustment process of the first room and the second room may be accompanied.
Referring to fig. 2, the control method of the linkage fresh air device includes:
s201, obtaining the current first indoor temperature of the first room, the current second indoor temperature of the second room, the set temperatures of the first room and the second room and the current outdoor temperature of the outdoor environment, wherein the set temperature is the set temperature of the temperature adjusting devices of the first room and the second room.
The current first indoor temperature can be obtained through a first temperature sensor of the first room, the first temperature sensor can be independently arranged and can be arranged on the first fresh air device, and the first temperature sensor can also be arranged on the air conditioner under the condition that the first fresh air device and the air conditioner are respectively independent equipment.

The current outdoor temperature of the outdoor environment may be obtained by a third temperature sensor disposed outdoors.
The set temperature can be set by the user, and the set temperature can be recommended by adopting the existing health temperature recommendation algorithm. The same set temperature is adopted in first room and second room, like this, when the user removes between first room and second room, reducible user's cold and hot difference in temperature feels, improves user's temperature comfort level and experiences.
In the heating condition, the temperature adjusting device can be heating equipment such as an air conditioner, an electric heater, an electric hot air and the like.
In the case of refrigeration, the temperature adjusting device may be an air conditioner.
Moreover, the air conditioner in the embodiment of the application can be a multi-split air conditioner, a split air conditioner or a central air conditioner. The split-type air conditioner refers to that one outdoor unit corresponds to one indoor unit.
S202, under the condition that the current first indoor temperature is lower than the current outdoor temperature, the current outdoor temperature is lower than the set temperature, and the set temperature is lower than the current second indoor temperature, or under the condition that the current first indoor temperature is higher than the current outdoor temperature, the current outdoor temperature is higher than the set temperature, and the set temperature is higher than the current second indoor temperature, the current first temperature difference value of the current first indoor temperature and the set temperature and the current second temperature difference value of the second indoor temperature and the set temperature are obtained.
S203, if the current first temperature difference is greater than or equal to the first temperature threshold, determining a current first fresh air rate according to the current first temperature difference, wherein the current first fresh air rate is positively correlated with the current first temperature difference; and if the current second temperature difference is greater than or equal to the second temperature threshold, determining a current second fresh air rate according to the current second temperature difference, wherein the current second fresh air rate is positively correlated with the current second temperature difference.
The specific implementation mode of the step comprises the following steps:
if the current first temperature difference value is larger than or equal to the first temperature threshold value and the current second temperature difference value is larger than or equal to the second temperature threshold value, determining the current first fresh air rate according to the current first temperature difference value and determining the current second fresh air rate according to the current second temperature difference value;
if the current first temperature difference is larger than or equal to the first temperature threshold and the current second temperature difference is smaller than the second temperature threshold, determining the current first fresh air rate according to the current first temperature difference and determining the current second fresh air rate according to the current second temperature difference;
and if the current first temperature difference value is smaller than the first temperature threshold value and the current second temperature difference value is larger than or equal to the second temperature threshold value, determining the current first fresh air rate according to the current first temperature difference value, and determining the current second fresh air rate according to the current second temperature difference value.
In a specific application, the fresh air rate (the current first fresh air rate or the current second fresh air rate) can be represented by a fan speed of the fresh air fan, and the fan speed can be measured by a fan current or a speed sensor.
In the above embodiment, the positive correlation between the current first fresh air rate and the current first temperature difference, and the positive correlation between the current second fresh air rate and the current second temperature difference, may be obtained by a person skilled in the art through experiments, for example, the indoor temperature of the first room is raised from the first temperature to the set temperature, the indoor temperature of the second room is lowered from the second temperature to the set temperature, in each adjustment process, the positive correlation between the current first fresh air rate and the current first temperature difference, and the positive correlation between the current second fresh air rate and the current second temperature difference are respectively adjusted, and the set parameters of the air conditioner of the first room and the air conditioner of the second room are maintained unchanged; after the test is finished, counting the time length required by the indoor temperature of the first room and the indoor temperature of the second room which are regulated from the beginning to be stable to the set temperature in each test, and recording the corresponding relation between the current first fresh air rate and the current first temperature difference value in the adjustment process corresponding to the shortest time length and the positive correlation relation between the current second fresh air rate and the current second temperature difference value.
And S204, if the current first temperature difference is smaller than the first temperature threshold value and the current second temperature difference is smaller than the second temperature threshold value, taking the first preset fresh air rate as the current first fresh air rate and the second preset fresh air rate as the current second fresh air rate, so that the current pressure difference between the current first pressure of the first room and the current second pressure of the second room is smaller than or equal to the pressure neglect threshold value.
For the situation that the current first temperature difference value is greater than or equal to the first temperature threshold value and the current second temperature difference value is smaller than the second temperature threshold value, even if the current second temperature difference value is smaller than the second temperature threshold value, the current second fresh air rate is positively correlated with the current second temperature difference value, so that the current second fresh air rate cannot be overlarge, excessive cold or heat cannot be introduced into a second room from the outside, and the influence on the stability of the current second indoor temperature reaching the set temperature is small;
for the situation that the current first temperature difference value is smaller than the first temperature threshold value and the current second temperature difference value is larger than or equal to the second temperature threshold value, even if the current first temperature difference value is smaller than the second temperature threshold value, the current first fresh air speed rate is positively correlated with the current first temperature threshold value, so that the current first fresh air speed rate cannot be overlarge, and excessive heat or cold cannot be introduced into the first room from the outside; the influence of the stability of the current first indoor temperature reaching the set temperature is small.
For example, if the volume difference between the first room and the second room is larger, the larger the velocity difference is, the larger the velocity difference between the first preset fresh air velocity and the second preset fresh air velocity needs to be maintained in order to make the current pressure difference between the first pressure and the second pressure smaller than or equal to the pressure ignoring threshold; if the difference between the volumes of the first room and the second room is smaller, in order to make the current pressure difference between the current first pressure and the current second pressure smaller than or equal to the pressure neglect threshold, the smaller the difference between the first preset fresh air rate and the second preset fresh air rate is required to be maintained.
In a case where a current pressure difference value between a current first pressure of the first room and a current second pressure of the second room is less than or equal to a pressure neglect threshold, it is possible to cause heat flow between the first room and the second room to be neglected by a temperature control model of an air conditioner of the first room and a temperature control model of an air conditioner of the second room. This is related to the control accuracy of the temperature control model of the air conditioner, the higher the control accuracy of the temperature control model of the air conditioner is, the less the heat flow can be ignored; the lower the control accuracy of the temperature control model of the air conditioner, the more heat flows that can be ignored.
Under the condition that the heat flows which can be ignored by the temperature control model of the air conditioner of the first room and the temperature control model of the air conditioner of the second room are not changed, the larger the cross-sectional areas of the air flow openings of the first room and the second room are, the smaller the pressure ignoring threshold value is; the smaller the cross-sectional area of the air flow of the first room and the second room, the larger the pressure neglecting threshold.
S205, controlling the first fresh air device according to the current first fresh air rate, and controlling the second fresh air device according to the current second fresh air rate.
The first room is provided with a first fresh air device which is used for sucking outdoor air into the first room, the second room is provided with a second fresh air device which is used for sucking the outdoor air into the second room, and air flows between the first room and the second room.
When the current first indoor temperature is lower than the current outdoor temperature, the current outdoor temperature is lower than the set temperature, and the set temperature is lower than the current second indoor temperature, or when the current first indoor temperature is higher than the current outdoor temperature, the current outdoor temperature is higher than the set temperature, and the set temperature is higher than the current second indoor temperature, fresh air is provided for the first room and the second room, which are beneficial to enabling the current first indoor temperature and the current second indoor temperature to change towards the direction approaching to the set temperature, so that the energy consumption of the air conditioner can be reduced in the process of adjusting the temperature of the first room by using the air conditioner and adjusting the temperature of the second room by using the air conditioner; in addition, in the process that the current first indoor temperature and the current second indoor temperature change towards the direction approaching the set temperature, if the current first temperature difference is greater than or equal to the first temperature threshold, the current first fresh air rate is positively correlated with the first temperature difference, and if the second temperature difference is greater than or equal to the second temperature threshold, the current second fresh air rate is positively correlated with the second temperature difference, so that more outdoor air is favorably utilized to adjust the current first indoor temperature of the first room, or the current second indoor temperature of the second room is adjusted, the current first indoor temperature of the first room can be changed towards the direction approaching the set temperature relatively quickly, and the current second indoor temperature of the second room is changed towards the direction approaching the set temperature relatively quickly. Furthermore, if the current first temperature difference is smaller than the first temperature threshold and the current second temperature threshold is smaller than the second temperature threshold, the first fresh air device of the first room is controlled according to the first preset fresh air rate, the second fresh air device of the second room is controlled according to the second preset fresh air rate, so that the current pressure difference between the first pressure of the first room and the current second pressure of the second room is smaller than or equal to the pressure neglected threshold, the air flow of the two rooms is reduced as much as possible, the heat flow of the two rooms is reduced, the adverse effect of the heat flow between the two rooms on the respective temperature stability of the two rooms is reduced, and the current first indoor temperature of the first room and the current second indoor temperature of the second room can be stabilized at the set temperature more quickly.
The embodiment of the application relates to two conditions: the current first indoor temperature is less than the current outdoor temperature, the current outdoor temperature is less than the set temperature, the set temperature is less than the current second indoor temperature, and the current first indoor temperature is greater than the current outdoor temperature, the current outdoor temperature is greater than the set temperature, and the set temperature is greater than the current second indoor temperature.
The following effects of the control method of the linkage fresh air device provided by the embodiment of the application are exemplarily described in combination with the situations that the current first indoor temperature is less than the current outdoor temperature, the current outdoor temperature is less than the set temperature, and the set temperature is less than the current second indoor temperature:
when the first fresh air device is controlled according to the current first fresh air rate, on one hand, outdoor air can be sucked into the first room, and the freshness of the air in the first room is adjusted, for example, the larger the current first fresh air rate is, the more favorable the freshness of the air in the first room is; in addition, the current first indoor temperature of the first room is lower than the current outdoor temperature, and the outdoor air is also beneficial to improving the current first indoor temperature, for example, the higher the current first fresh air rate is, the more beneficial is to improving the current first indoor temperature in the first room; on the basis of the effect, the first fresh air device is controlled according to the first fresh air speed, and the current first pressure of the first room can be adjusted to change the current pressure difference value between the current first pressure and the current second pressure of the second room, so that the air flow speed between the first room and the second room is changed, and the heat flow between the first room and the second room is adjusted.
Correspondingly, the current second fresh air rate is used for controlling the second fresh air rate, when the second fresh air device is controlled according to the current second fresh air rate, on one hand, outdoor air can be sucked into the second room, and the freshness of the air in the second room is adjusted, for example, the larger the current second fresh air rate is, the more the freshness of the air in the second room is favorably improved; the current outdoor temperature is lower than the current second indoor temperature of the second room, and the outdoor air is also beneficial to reducing the current second indoor temperature, for example, the higher the current first fresh air rate is, the more beneficial to reducing the current second indoor temperature in the second room is; on the basis of the function, the second fresh air device is controlled according to the second fresh air rate, and the current second pressure of the second room can be adjusted to change the current pressure difference between the current second pressure and the current first pressure of the first room, change the air flow rate between the first room and the second room, and further adjust the heat flow between the first room and the second room.
The regulation of the heat flow between the first room and the second room is as follows:
under the condition that the current first temperature difference value is larger than or equal to the first temperature threshold value and/or the current second temperature difference value is larger than or equal to the second temperature threshold value, the current first fresh air rate is positively correlated with the current first temperature difference value so as to introduce more outdoor air into the first room, namely, more heat is introduced into the first room from the outside, so that the current first indoor temperature is improved more quickly, and less electric energy can be consumed in the process that the air conditioner of the first room adjusts the current first indoor temperature to the set temperature.
Correspondingly, the current second fresh air rate is positively correlated with the current second temperature difference value, so that more outdoor air is introduced into the second room, namely more cold is introduced into the second room from the outside, the current second indoor temperature is reduced more quickly, and less electric energy can be consumed in the process that the current second indoor temperature is adjusted to the set temperature by the air conditioner in the second room.
Further, in the process of controlling the first fresh air device according to the current first fresh air rate and controlling the second fresh air device according to the current second fresh air rate, the current first pressure of the first room and the current second pressure of the second room are difficult to be completely equal, that is, in the control process, a certain amount of heat tends to flow between the first room and the second room.
If the current first pressure of the first room is higher than the current second pressure of the second room, the air of the first room flows to the second room, and the cold energy of the first room is carried to the second room, and because the current first indoor temperature is lower than the current outdoor temperature, the cold energy carried by the air with certain quality flowing into the second room from the first room is larger than the cold energy carried by the air with certain quality sucked into the second room from the outside, so the technical scheme is favorable for reducing the current second indoor temperature of the second room as soon as possible, and reduces the electric energy required by the air conditioner to adjust the current second indoor temperature of the second room to the set temperature; meanwhile, the first room discharges air with lower temperature to the second room, and air with higher temperature is sucked from the outside, so the technical scheme is beneficial to improving the current first indoor temperature of the first room as soon as possible, and reduces the electric energy required by the air conditioner to adjust the current first temperature of the first room to the set temperature.
If the current first pressure of the first room is lower than the current second pressure of the second room, the air of the second room flows to the first room, and carries the heat of the second room to the first room, and because the current second indoor temperature is higher than the current outdoor temperature, the heat carried by the certain mass of air flowing into the first room from the second room is greater than the heat carried by the certain mass of air sucked into the first room from the outside, so the technical scheme is favorable for improving the current first indoor temperature of the first room as soon as possible, and reduces the electric energy required by the air conditioner to adjust the current first indoor temperature of the first room to the set temperature; meanwhile, the second room discharges air with higher temperature to the first room, and the air with lower temperature is sucked from the outside, so the technical scheme is favorable for reducing the current second indoor temperature of the second room as soon as possible, and reduces the electric energy required by the air conditioner to adjust the current second indoor temperature of the second room to the set temperature.
That is, when the current first temperature difference is greater than or equal to the first temperature threshold, and/or the current second temperature difference is greater than or equal to the second temperature threshold, the goal of relatively quickly eliminating the current first temperature difference and the current second temperature difference is to promote the heat flow in the two rooms, and the goal of relatively quickly eliminating the current first temperature difference and the current second temperature difference is to promote the heat flow in the two rooms.
The effect of the control method of the linkage fresh air device provided by the embodiment of the application is exemplarily described below by combining the condition that the current first indoor temperature is greater than the current outdoor temperature, the current outdoor temperature is greater than the set temperature, and the set temperature is greater than the current second indoor temperature.
When the first fresh air device is controlled according to the current first fresh air rate, on one hand, outdoor air can be sucked into the first room, and the freshness of the air in the first room can be adjusted, for example, the greater the current first fresh air rate is, the more favorable the freshness of the air in the first room is; moreover, the current first indoor temperature of the first room is greater than the current outdoor temperature, and the outdoor air is also beneficial to reducing the current first indoor temperature, for example, the greater the current first fresh air rate is, the more beneficial the reduction of the current first indoor temperature in the first room is; on the basis of the effect, the first fresh air device is controlled according to the first fresh air speed, and the current first pressure of the first room can be adjusted to change the current pressure difference value between the current first pressure and the current second pressure of the second room, so that the air flow speed between the first room and the second room is changed, and the heat flow between the first room and the second room is adjusted.
Correspondingly, the current second fresh air rate is used for controlling the second fresh air rate, when the second fresh air device is controlled according to the current second fresh air rate, on one hand, outdoor air can be sucked into the second room, and the freshness of the air in the second room is adjusted, for example, the larger the current second fresh air rate is, the more the freshness of the air in the second room is favorably improved; the current outdoor temperature is higher than the current second indoor temperature of the second room, and the outdoor air is also beneficial to improving the current second indoor temperature, for example, the higher the current first fresh air rate is, the more beneficial to improving the current second indoor temperature in the second room is; on the basis of the function, the second fresh air device is controlled according to the second fresh air rate, and the current second pressure of the second room can be adjusted to change the current pressure difference between the current second pressure and the current first pressure of the first room, change the air flow rate between the first room and the second room, and further adjust the heat flow between the first room and the second room.
The regulation of the heat flow between the first room and the second room is as follows:
under the condition that the current first temperature difference value is larger than or equal to the first temperature threshold value and/or the current second temperature difference value is larger than or equal to the second temperature threshold value, the current first fresh air rate is positively correlated with the current first temperature difference value so as to introduce more outdoor air into the first room, namely, more cold energy is introduced into the first room from the outside, so that the current first indoor temperature is reduced more quickly, and less electric energy can be consumed in the process that the air conditioner of the first room adjusts the current first indoor temperature to the set temperature.
Correspondingly, the current second fresh air rate is positively correlated with the current second temperature difference value, so that more outdoor air is introduced into the second room, namely more heat is introduced into the second room from the outside, the current second indoor temperature is improved more quickly, and less electric energy can be consumed in the process that the current second indoor temperature is adjusted to the set temperature by the air conditioner in the second room.
Further, in the process of controlling the first fresh air device according to the current first fresh air rate and the second fresh air device according to the current second fresh air rate, the current first pressure of the first room and the current second pressure of the second room are difficult to be completely equal, that is, in the control process, a certain amount of heat flow often exists between the first room and the second room.
If the current first pressure of the first room is higher than the current second pressure of the second room, the air of the first room flows to the second room to carry the heat of the first room to the second room, and because the current first indoor temperature is higher than the current outdoor temperature, the heat carried by the certain mass of air flowing into the second room from the first room is higher than the heat carried by the certain mass of air sucked into the second room from the outside, so the technical scheme is favorable for improving the current second indoor temperature of the second room as soon as possible and reducing the electric energy required by the air conditioner to adjust the current second indoor temperature of the second room to the set temperature; meanwhile, the first room discharges air with higher temperature to the second room, and air with lower temperature is sucked from the outside, so the technical scheme is favorable for reducing the current first indoor temperature of the first room as soon as possible, and reduces the electric energy required by the air conditioner to adjust the current first temperature of the first room to the set temperature.
If the current first pressure of the first room is lower than the current second pressure of the second room, the air of the second room flows to the first room, and carries the heat of the second room to the first room, and because the current second indoor temperature is lower than the current outdoor temperature, the cold quantity carried by the air with certain quality flowing into the first room from the second room is greater than the cold quantity carried by the air with certain quality sucked into the first room from the outside, so the technical scheme is favorable for reducing the current first indoor temperature of the first room as soon as possible, and reduces the electric energy required by the air conditioner to adjust the current first indoor temperature of the first room to the set temperature; meanwhile, the second room discharges air with lower temperature to the first room, and the air with higher temperature is sucked from the outside, so the technical scheme is favorable for improving the current second indoor temperature of the second room as soon as possible, and reduces the electric energy required by the air conditioner to adjust the current second indoor temperature of the second room to the set temperature.
That is, when the current first temperature difference is greater than or equal to the first temperature threshold, and/or the current second temperature difference is greater than or equal to the second temperature threshold, the goal of relatively quickly eliminating the current first temperature difference and the current second temperature difference is to promote the heat flow in the two rooms, and the goal of relatively quickly eliminating the current first temperature difference and the current second temperature difference is to promote the heat flow in the two rooms.
The current first temperature difference value is continuously reduced, and the current second temperature difference value is continuously reduced. Under the condition that the current first temperature difference value is smaller than the first temperature threshold value and the current second temperature difference value is smaller than the second temperature threshold value, the determination strategies of the current first fresh air rate and the current second fresh air rate are changed, and at the moment, the overall target for determining the current first fresh air rate and the current second fresh air rate is as follows: the method comprises the following steps of enabling the difference value of the current pressure intensity of the current first pressure intensity of the first room and the current pressure intensity of the current second pressure intensity of the second room to be smaller than or equal to a pressure intensity neglecting threshold value, further enabling the air flowing speed between the first room and the second room to be reduced to be within an expected range, and even if the heat flowing speed between the first room and the second room is reduced to be within the expected range, the specific scheme is as follows: and taking the first preset fresh air rate as the current first fresh air rate, and taking the second preset fresh air rate as the current second fresh air rate.
Therefore, after the heat flow rate between the first room and the second room is reduced to be within an expected range, the mutual influence of the temperature rising process of the first room and the temperature reducing process of the second room is reduced, the external interference of the temperature rising model of the first room is reduced, the external interference of the temperature reducing model of the second room is reduced, the current first room temperature is stabilized at the set temperature quickly by the air conditioner of the first room, and the current second room temperature is stabilized at the set temperature quickly by the air conditioner of the second room.
Optionally, the control method of the linkage fresh air device further includes: and taking the first preset fresh air rate as the current first fresh air rate under the condition that the current first indoor temperature is greater than or equal to the current outdoor temperature and the current first indoor temperature is less than the set temperature, or under the condition that the current first indoor temperature is less than or equal to the current outdoor temperature and the current first indoor temperature is greater than the set temperature.
Under the condition that the temperature difference value between the current outdoor temperature and the set temperature is smaller than a first temperature threshold, if the current first temperature difference value is smaller than the first temperature threshold, judging the magnitude relation between the current first indoor temperature and the current outdoor temperature: if the current first indoor temperature is within a range defined by the current outdoor temperature and the set temperature, taking a first preset fresh air rate as the current first fresh air rate; and if the current first indoor temperature is out of the range defined by the current outdoor temperature and the set temperature, determining the current first fresh air rate according to the current first temperature difference.
Under the condition that the temperature difference between the current outdoor temperature and the set temperature is greater than or equal to a first temperature threshold, if the current first temperature difference is greater than or equal to the first temperature threshold, judging the magnitude relation between the current first indoor temperature and the current outdoor temperature: determining a current first fresh air rate according to the first temperature difference if the current first indoor temperature is outside a range defined by the current outdoor temperature and the set temperature; and if the current first indoor temperature is within the range defined by the current outdoor temperature and the set temperature, determining the first preset fresh air rate as the current first fresh air rate.
Fig. 3 is a schematic diagram of a process for determining a current first fresh air rate according to an embodiment of the present application.
Referring to fig. 3, determining the current first fresh air rate according to the current first temperature difference includes:
s301, obtaining a current third temperature difference value between the current first indoor temperature and the current outdoor temperature.
S302, determining a current first additional fresh air rate positively correlated with the product of the current first temperature difference and the current third temperature difference.
For example, the product of the current first temperature difference and the current third temperature difference may be in a linear relationship with the current first additional fresh air rate. The positive correlation coefficient can be obtained through a test mode, so that the sum of the current first additional fresh air rate and the third preset fresh air rate is smaller than or equal to the maximum fresh air rate of the first fresh air device and larger than or equal to the first preset fresh air rate.
Alternatively, determining the current first additional fresh air rate positively correlated to the product of the current first temperature difference and the current third temperature difference may include: determining a first internal and external ventilation rate according to the product of the current first temperature difference value and the current third temperature difference value; obtaining the current second air quality of the second room, wherein the smaller the numerical value of the current second air quality is, the higher the air quality in the second room is; determining a first flow coefficient which is negatively related to the current second air quality according to the negative correlation relationship between the air quality and the air flow quantity in the room; determining a current first indoor ventilation rate according to the product of the current first temperature difference value and the first flow coefficient; and determining a current first additional fresh air rate according to the sum of the first internal and external air exchange rate and the first indoor air exchange rate.
In this way, a better healthy air experience is also obtained for the user.
