In some embodiments, the smart home system includes the control device of the linkage fresh air device provided in the foregoing embodiments.
The control method and device for the linkage fresh air device and the intelligent home system provided by the embodiment of the application can achieve the following technical effects:
when the current outdoor temperature is less than or equal to the current second indoor temperature, the current second indoor temperature is less than the current first indoor temperature, and the current first indoor temperature is less than the set temperature, the first room and the second room are both in the temperature rising process, and the process of introducing the outdoor air into the first room by the first fresh air device has the effect of hindering the temperature rising process of the first room, and the process of introducing the outdoor air into the second room by the second fresh air device has the effect of hindering the temperature rising process of the second room; when the current outdoor temperature is larger than or equal to the current second indoor temperature, the current second indoor temperature is larger than the current first indoor temperature, and the current first indoor temperature is larger than the set temperature, the first room and the second room are both in the cooling process, in addition, the process of introducing the outdoor air into the first room by the first fresh air device has the blocking effect on the cooling process of the first room, the process of introducing the outdoor air into the second room by the second fresh air device has the blocking effect on the cooling process of the second room.
For the first room, the larger the difference between the outdoor temperature and the current first ambient temperature is, the larger the influence of the outdoor air per unit volume on the temperature adjusting process of the first room is, and the current first temperature difference is negatively related to the current first fresh air rate, so that the influence of the air introduced into the first room from the outside on the temperature adjusting process of the first room can be kept to be small, and thus, the temperature adjusting device can be ensured to adjust the temperature of the first room to the set temperature more stably in the process of adjusting the temperature of the first room by the temperature adjusting device.
For the second room, the pressure intensity of the first room is greater than the pressure intensity of the second room, then the air in the first room can flow to the second room, in the temperature rising process of the first room and the second room, the heat in the first room can flow to the second room, the heat flowing from the first room to the second room has promotion effect on the temperature rising process of the second room, in the temperature lowering process of the first room and the second room, the cold in the first room can flow to the second room, and the cold flowing from the first room to the second room has promotion effect on the temperature lowering process of the second room; at the same time, the air flowing from the outside to the second room has a hindering effect on the temperature change process of the second room.
The correlation between the current second fresh air rate and the current third temperature difference value is used for representing the blocking effect of the air flowing from the outdoor to the second room on the temperature adjusting process of the second room; the correlation between the current second fresh air rate, the current first fresh air rate and the current second temperature difference is used to represent the promotion effect of the air flowing from the first room to the second room on the temperature adjustment process of the second room, and the second room maintains stable interference, which means that the above-mentioned hindering effect and promotion effect can be regarded as equal.
In the process that the current first indoor temperature changes to the set temperature, the current first temperature difference value between the current first indoor temperature and the set temperature has a trend of becoming larger, and the current first fresh air speed has a trend of becoming smaller; the current second fresh air rate is positively correlated with the current first fresh air rate, and the pressure difference value of the first pressure of the first room and the second pressure of the second room can be maintained.
The current second fresh air rate is negatively correlated with the current second temperature difference, if the current second temperature difference has a trend of increasing, the current second fresh air rate has a trend of decreasing, the air flow rate flowing from the first room to the second room has a trend of increasing, and the promotion effect of the air flowing from the first room to the second room on the temperature change of the second room has a trend of increasing; meanwhile, if the current second temperature difference value has a trend of becoming larger, the current third temperature difference value has a trend of becoming smaller, the current second fresh air rate has a trend of becoming larger, the air flow rate from the outdoor to the second room has a trend of becoming larger, and the blocking effect of the air flowing from the outdoor to the second room on the temperature variation process of the second room has a trend of becoming larger. The trend of increasing the promotion effect and the trend of increasing the obstruction effect on the temperature change of the second room can maintain relatively stable temperature interference of the second room, and the temperature adjusting device can more smoothly adjust the temperature of the second room from the current second room temperature to the set temperature.
If the current second temperature difference value has a trend of becoming smaller, the current second fresh air rate has a trend of becoming larger, the air flow rate flowing from the first room to the second room has a trend of becoming smaller, and the promotion effect of the air flowing from the second room to the second room on the temperature change of the second room has a trend of becoming smaller; meanwhile, if the current second temperature difference value has a trend of becoming smaller, the current third temperature difference value has a trend of becoming larger, the current second fresh air rate has a trend of becoming smaller, the air flow rate from the outdoor to the second room has a trend of becoming smaller, and the blocking effect of the air flowing from the outdoor to the second room on the temperature change of the second room has a trend of becoming smaller. The trend of the promotion effect and the trend of the reduction of the obstruction effect on the temperature change of the second room can ensure that the relatively stable temperature interference of the second room is maintained, and the temperature adjusting device can more stably adjust the temperature of the second room from the current second indoor temperature to the set temperature.
Therefore, by adopting the technical scheme provided by the embodiment of the application, the temperature regulating device can be used for regulating the temperature of the first room from the current first indoor temperature to the set temperature more stably, and regulating the temperature of the second room from the current second indoor temperature to the set temperature more stably, so that the temperature fluctuation process of the first room and the second room is shortened, and the temperatures of the first room and the second room can be stabilized at the set temperature more quickly.

The second temperature sensor of accessible second room obtains current second indoor temperature, and this second temperature sensor can independently set up, can set up on second new trend device, under second new trend device and air conditioner were the independent equipment respectively, and second temperature sensor still can set up on the air conditioner.
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 outdoor temperature is less than or equal to the current second indoor temperature, the current second indoor temperature is less than the current first indoor temperature, and the current first indoor temperature is less than the set temperature, or under the condition that the current outdoor temperature is greater than or equal to the current second indoor temperature, the current second indoor temperature is greater than the current first indoor temperature, and the current first indoor temperature is greater than the set temperature, the current first temperature difference value between the current first indoor temperature and the current outdoor temperature is obtained.
The current outdoor temperature is less than or equal to the current second indoor temperature, the current second indoor temperature is less than the current first indoor temperature, and the current first indoor temperature is less than the set temperature, which is the condition that the first room and the second room are heated simultaneously. In this case, the first fresh air device in the first room has an effect of hindering the temperature rise process of the first room from the outside, and the second fresh air device in the second room has an effect of hindering the temperature rise process of the second room from the outside.
The current outdoor temperature is greater than or equal to the current second indoor temperature, the current second indoor temperature is greater than the current first indoor temperature, and the current first indoor temperature is greater than the set temperature, which is the condition that the first room and the second room are cooled simultaneously. In this case, the first fresh air device in the first room has an effect of hindering the temperature reduction process of the first room from the air introduced to the first room from the outside, and the second fresh air device in the second room has an effect of hindering the temperature reduction process of the second room from the air introduced to the second room from the outside.
S203, determining a current first fresh air rate corresponding to the current first temperature difference value according to the negative correlation relationship between the temperature difference value and the fresh air rate, so that the first room maintains stable temperature interference.
The larger the temperature difference between the first indoor temperature and the outdoor temperature of the first room, the greater the influence on the first indoor temperature per unit of air introduced into the first room from the outside; the smaller the temperature difference between the first indoor temperature and the outdoor temperature of the first room, the smaller the influence on the first indoor temperature per unit of air introduced from the outside to the first room.
For the first room, if the change of the first indoor temperature of the first room is only affected by the temperature adjusting device in the first room, the temperature interference of the first room is zero; if the change in the first indoor temperature of the first room is affected not only by the temperature adjustment device in the first room but also by other factors, such as fresh air introduced into the first room from the outside, the temperature disturbance of the first room is the effect of the other factors on the change in the first indoor temperature. The first room maintains a stable temperature disturbance, which means that the degree of the resistance effect of the air introduced into the first room from the outside on the temperature change of the first room is maintained stable.
The negative correlation relationship between the temperature difference and the fresh air speed is maintained, so that the temperature interference of the air introduced from the outside to the first room can be kept stable. When the first room is in the process of temperature increase, the air introduced from the outside into the first room has an effect of hindering the process of temperature increase of the first room; when the first room is in the process of temperature reduction, the air introduced from the outside into the first room has an effect of hindering the process of temperature reduction of the first room.
The negative correlation relationship between the temperature difference and the fresh air rate can be obtained in a test mode and then stored in a database in a form of a one-to-one correspondence data table, or stored in the database in a form of a relational expression between the temperature difference and the fresh air rate.
After the current first temperature difference value is obtained, the current first fresh air speed corresponding to the current first temperature difference value can be obtained by inquiring the database or substituting the current first temperature difference value into a relational expression stored in the database.
The current first fresh air rate is used for controlling a first fresh air device of the first room, and the first fresh air rate can represent the fan rotating speed, the flow rate, the gear position and the like of the first fresh air device.
S204, obtaining a current second temperature difference value between the current first indoor temperature and the current second indoor temperature, and a current third temperature difference value between the current second indoor temperature and the current outdoor temperature.
S205, determining a current second fresh air rate which is positively correlated with the current first fresh air rate and negatively correlated with the current second temperature difference and the current third temperature difference, and maintaining stable temperature interference of the second room.
The current second fresh air rate is used to control a second fresh air device in a second room. In the embodiment of the present application, the first fresh air device in the first room can maintain a slight positive pressure in the first room, and the second fresh air device in the second room can maintain a slight positive pressure in the second room, that is, the first pressure in the first room is higher than the outdoor pressure, and the second pressure in the second room is higher than the outdoor pressure. And in the control process of the linkage fresh air device, the pressure intensity of the first room is greater than the pressure intensity of the second room.
The combination of the current second fresh air rate and the current third temperature difference can be used to measure the effect of the air introduced into the second room from the outside on the temperature change of the second room: the larger the current second fresh air rate is, the larger the blocking effect of the air introduced into the second room from the outside on the temperature change of the second room is; the larger the current third temperature difference is, the more the air introduced into the second room from the outside has a resistance to the temperature change of the second room.
The pressure in the first room is greater than the pressure in the second room, and the first room and the second aspect have an air flow, meaning that the air in the first room is able to flow to the second room. When the first room and the second room are both in the temperature rising process, the current first indoor temperature of the first room is higher than the current second indoor temperature of the second room, and the air flowing from the first room to the second room can bring heat from the first room to the second room, so that the temperature rising process of the second room is facilitated, namely, the air flowing from the first room to the second room has a promoting effect on the temperature change of the second room; when the first room and the second room are in the cooling process, the current first indoor temperature of the first room is lower than the current second indoor temperature of the second room, and the air flowing from the first room to the second room can bring the cold energy into the second room from the first room, so that the cooling process of the second room is facilitated, namely, the air flowing from the first room to the second room has a promoting effect on the temperature change of the second room.
The current first fresh air rate and the current second fresh air rate can be used to measure a current air flow rate from the first room to the second room, and the combination of the second temperature difference and the current air flow rate can be used to measure an effect of air flowing from the first room to the second room on a temperature change in the second room: the greater the current air flow rate, the greater the contribution of the air flowing from the first room to the second room to the temperature history of the second room; the greater the current second temperature difference, the greater the contribution of the air flowing from the first room to the second room to the temperature profile of the second room.
For the second room, if the change of the second indoor temperature of the second room is only affected by the temperature adjusting device arranged in the second room, the temperature interference of the second room is zero; if the change in the second indoor temperature of the second room is affected not only by the temperature adjustment device of the second room but also by other factors such as fresh air introduced into the second room from the outside or air flowing into the second room from the first room, the temperature disturbance of the second room is the effect of these other factors on the change in the first indoor temperature.
Further, the second room maintains a stable temperature disturbance, and the degree of change of the effect of the air introduced into the second room from the outside on the resistance of the temperature change in the second room is the same as or can be regarded as the same as (the difference between) the degree of change of the effect of the air flowing into the second room from the first room on the promotion of the temperature change in the second room. In a specific application, the combination of the effect of the air introduced into the second room from the outside on the inhibition of the temperature change of the second room and the effect of the air flowing into the second room from the first room on the promotion of the temperature change of the second room can be expressed as the effect of the promotion of the temperature change of the second room, and can also be expressed as the effect of the inhibition of the temperature change of the second room, and even can be expressed as the effect of the zero on the temperature change of the second room.
Specifically, under the goal of maintaining stable temperature interference in the second room, the corresponding relationship among the first fresh air rate, the second temperature difference, the third temperature difference and the second fresh air rate can be obtained through a test mode, and stored in the database in a one-to-one correspondence data table mode, and after the current first fresh air rate, the current second temperature difference and the current third temperature difference are obtained, the database is queried, so that the current second fresh air rate corresponding to the current first fresh air rate, the current second temperature difference and the current third temperature difference can be obtained.
Or, under the goal of maintaining stable temperature interference in the second room, a relational formula of the first fresh air rate, the second temperature difference, the third temperature difference and the second fresh air rate is established, and after the current first fresh air rate, the current second temperature difference and the current third temperature difference are obtained, the current first fresh air rate, the current second temperature difference and the current third temperature difference are substituted into the relational formula, so that the current second fresh air rate corresponding to the current first fresh air rate, the current second temperature difference and the current third temperature difference can be obtained.
As a supplementary explanation, in the process of air flowing from the first room to the second room, for the first room, outdoor air flows from the outside into the first room, so that the first pressure of the first room is higher than the outdoor pressure, and the air in the first room can leak to the outside through the gap of the first room on the one hand and flow to the second room on the other hand. In this process, the air flowing from the first room to the second room does not have a significant effect on the temperature profile of the first room.
S206, 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 fresh air device and the second fresh air device are controlled according to the mode, so that the pressure intensity of the first room is higher than that of the second room.
When the current outdoor temperature is less than or equal to the current second indoor temperature, the current second indoor temperature is less than the current first indoor temperature, and the current first indoor temperature is less than the set temperature, the first room and the second room are both in the temperature rising process, and the process of introducing the outdoor air into the first room by the first fresh air device has the effect of hindering the temperature rising process of the first room, and the process of introducing the outdoor air into the second room by the second fresh air device has the effect of hindering the temperature rising process of the second room; when the current outdoor temperature is larger than or equal to the current second indoor temperature, the current second indoor temperature is larger than the current first indoor temperature, and the current first indoor temperature is larger than the set temperature, the first room and the second room are both in the cooling process, in addition, the process of introducing the outdoor air into the first room by the first fresh air device has the blocking effect on the cooling process of the first room, the process of introducing the outdoor air into the second room by the second fresh air device has the blocking effect on the cooling process of the second room.
For the first room, the larger the difference between the outdoor temperature and the current first ambient temperature is, the larger the influence of the outdoor air per unit volume on the temperature adjusting process of the first room is, and the current first temperature difference is negatively related to the current first fresh air rate, so that the influence of the air introduced into the first room from the outside on the temperature adjusting process of the first room can be kept to be small, and thus, the temperature adjusting device can be ensured to adjust the temperature of the first room to the set temperature more stably in the process of adjusting the temperature of the first room by the temperature adjusting device.
For a second room, the pressure intensity of the first room is greater than that of the second room, then the air in the first room can flow to the second room, in the heating processes of the first room and the second room, the heat in the first room can flow to the second room, the heat flowing from the first room to the second room has a promoting effect on the heating process of the second room, in the cooling processes of the first room and the second room, the cold in the first room can flow to the second room, and the cold flowing from the first room to the second room has a promoting effect on the cooling process of the second room; at the same time, the air flowing from the outside to the second room has a hindering effect on the temperature change process of the second room.
The correlation between the current second fresh air rate and the current third temperature difference value is used for representing the blocking effect of the air flowing from the outdoor to the second room on the temperature adjusting process of the second room; the correlation between the current second fresh air rate and the current first fresh air rate and the current second temperature difference is used to represent the promotion effect of the air flowing from the first room to the second room on the temperature adjustment process of the second room, and the second room maintains stable interference, which means that the above-mentioned blocking effect and promotion effect can be regarded as equal.
In the process that the current first indoor temperature changes to the set temperature, the current first temperature difference value between the current first indoor temperature and the set temperature has a trend of becoming larger, and the current first fresh air speed has a trend of becoming smaller; the current second fresh air rate is positively correlated with the current first fresh air rate, and the pressure difference value of the first pressure of the first room and the second pressure of the second room can be maintained.
The current second fresh air rate is negatively correlated with the current second temperature difference, if the current second temperature difference has a trend of increasing, the current second fresh air rate has a trend of decreasing, the air flow rate flowing from the first room to the second room has a trend of increasing, and the promotion effect of the air flowing from the first room to the second room on the temperature change of the second room has a trend of increasing; meanwhile, if the current second temperature difference value has a trend of becoming larger, the current third temperature difference value has a trend of becoming smaller, the current second fresh air rate has a trend of becoming larger, the flow rate of the air from the outside to the second room has a trend of becoming larger, and the blocking effect of the air flowing from the outside to the second room on the temperature variation process of the second room has a trend of becoming larger. The trend of increasing the promotion effect and the trend of increasing the obstruction effect on the temperature change of the second room can maintain relatively stable temperature interference of the second room, and the temperature adjusting device can more smoothly adjust the temperature of the second room from the current second indoor temperature to the set temperature.
If the current second temperature difference value has a trend of becoming smaller, the current second fresh air rate has a trend of becoming larger, the air flow rate flowing from the first room to the second room has a trend of becoming smaller, and the promotion effect of the air flowing from the second room to the second room on the temperature change of the second room has a trend of becoming smaller; meanwhile, if the current second temperature difference value has a trend of becoming smaller, the current third temperature difference value has a trend of becoming larger, the current second fresh air rate has a trend of becoming smaller, the flow rate of the air from the outside to the second room has a trend of becoming smaller, and the blocking effect of the air flowing from the outside to the second room on the temperature change of the second room has a trend of becoming smaller. The trend of the promotion effect and the trend of the reduction of the obstruction effect on the temperature change of the second room can ensure that the relatively stable temperature interference of the second room is maintained, and the temperature adjusting device can more stably adjust the temperature of the second room from the current second indoor temperature to the set temperature.
Therefore, by adopting the technical scheme provided by the embodiment of the application, the temperature regulating device can be used for regulating the temperature of the first room from the current first indoor temperature to the set temperature more stably, and regulating the temperature of the second room from the current second indoor temperature to the set temperature more stably, so that the temperature fluctuation process of the first room and the second room is shortened, and the temperatures of the first room and the second room can be stabilized at the set temperature more quickly.
The determination of the current first fresh air rate is further explained below.
Determining the current first fresh air rate corresponding to the current first temperature difference according to the negative correlation between the temperature difference and the fresh air rate, which may include: obtaining a preset temperature blocking coefficient; and determining the current first fresh air rate corresponding to the current first temperature difference and the preset temperature barrier coefficient according to the first corresponding relation among the temperature difference, the fresh air rate and the temperature barrier coefficient.
The temperature obstruction coefficient in the first corresponding relation is used for representing the difference value of the first indoor temperature and the outdoor temperature of the first room, and the obstruction effect of the first fresh air speed of the first fresh air device on the temperature change process of the first room, and the temperature obstruction coefficient is a quantitative representation of the obstruction effect.
The temperature coefficient of hindrance in the first correspondence may be: a temperature change amount of the first room caused by air introduced from outside the first room to the first room per unit time period; alternatively, the air introduced into the first room from the outside of the room per unit time period carries heat or cold relative to the temperature in the first room.
The first corresponding relation among the temperature difference value, the fresh air speed and the temperature obstruction coefficient can be stored in a database in a one-to-one correspondence data table mode, and after the current first temperature difference value and the preset temperature obstruction coefficient are obtained, the current first fresh air speed corresponding to the current first temperature difference value and the preset temperature obstruction coefficient can be obtained by inquiring the database.
Or, the first corresponding relation among the temperature difference value, the fresh air rate and the temperature blocking coefficient can be pre-stored in a formula form, and after the current first temperature difference value and the preset temperature blocking coefficient are obtained, the current first temperature difference value and the preset temperature blocking coefficient are substituted into the formula, so that the current first fresh air rate corresponding to the current first temperature difference value and the preset temperature blocking coefficient can be obtained.
Referring to fig. 3, the process of obtaining the predetermined temperature barrier coefficient will be further described.
As shown in fig. 3, the process of obtaining the preset temperature barrier coefficient includes:
s301, obtaining a minimum first fresh air speed threshold value.
The minimum first fresh air rate threshold enables the first room to maintain a positive pressure of a preset pressure relative to the exterior of the room. The preset pressure can be set by one skilled in the art based on the conventional control experience of a single room single fresh air device.
S302, obtaining a current fourth temperature difference value between the set temperature and the current outdoor temperature.
S303, determining a minimum fresh air rate threshold and a minimum temperature blocking coefficient corresponding to the current fourth temperature difference according to the first corresponding relation among the temperature difference, the fresh air rate and the temperature blocking coefficient.
And S304, determining a preset temperature obstruction coefficient according to the minimum temperature obstruction coefficient.
The preset temperature barrier coefficient is greater than or equal to the minimum temperature barrier coefficient.
For example, the minimum temperature hindrance coefficient may be set as the preset temperature hindrance coefficient. Or, when both the current first indoor temperature and the current second indoor temperature approach the set temperature, in order to keep the first pressure of the first room greater than the second pressure of the second room, and the second pressure of the second room and the outdoor pressure greater than or equal to the preset pressure, the temperature may be increased based on the minimum temperature blocking coefficient, and the increased temperature blocking coefficient may be used as the preset temperature blocking coefficient.
Fig. 4 is a schematic diagram of a process for determining a temperature disturbance for maintaining a stable second room according to an embodiment of the present application.
As shown in fig. 4, the determination of the temperature disturbance to maintain the second room stable includes:
s401, estimating current air flow rates of the first room and the second room according to the current first fresh air rate and the current second fresh air rate.
The current air flow rate is positively correlated with the current first fresh air rate and negatively correlated with the current second fresh air rate.
For example, a corresponding relationship between the first fresh air rate, the second fresh air rate, and the air flow rates of the first room and the second room may be established in a test manner, the corresponding relationship may be in the form of a one-to-one corresponding data table, or may also be in the form of a relational expression, and based on the corresponding relationship, the current air flow rates corresponding to the current first fresh air rate and the current second fresh air rate may be obtained.
Further, the larger the volume of the first room, the higher the first fresh air velocity by a unit value, the smaller the influence on the first pressure in the first room, and the smaller the influence on the air flow velocity between the two rooms by the first fresh air velocity of the first fresh air device; similarly, the larger the volume of the second room is, the higher the second fresh air rate is by a unit value, the smaller the influence on the second pressure in the second room is, and the smaller the influence on the air flow rate between the two rooms by the second fresh air rate of the second fresh air device is.
Based thereon, estimating the current air flow rate of the first room and the second room based on the current first fresh air rate and the current second fresh air rate may include: obtaining a first volume of a first room and a second volume of a second room; determining a current airflow rate that is negatively correlated with the first volume, positively correlated with the second volume, positively correlated with the current first fresh air rate, and negatively correlated with the current second fresh air rate. This allows a more accurate current air flow rate to be obtained.
S402, determining an estimated temperature promotion coefficient corresponding to the current second temperature difference and the current air flow rate according to the corresponding relation among the temperature difference, the fresh air rate and the temperature promotion coefficient.
The temperature promotion coefficient is used for representing the promotion effect of the air flowing from the first room to the second room on the temperature change process of the second room, and the temperature promotion coefficient is a quantitative representation of the promotion effect.
The temperature promoting coefficient may be: the amount of change in temperature of the second room caused by the air flowing from the first room to the second room per unit time period; alternatively, the air flowing from the first room into the second room per unit time period is relative to the heat or cold carried by the second room.
The corresponding relation among the temperature difference, the fresh air speed and the temperature promoting coefficient can be stored in a database in a form of a one-to-one corresponding data table, and the estimated temperature promoting coefficient corresponding to the current second temperature difference and the current air flow speed can be determined by inquiring the database.
Or, the corresponding relation among the temperature difference value, the fresh air rate and the temperature promotion coefficient can be stored in advance in a formula form, and the current second temperature difference value and the current air flow rate are substituted into the formula, so that the estimated temperature promotion coefficient corresponding to the current second temperature difference value and the current air flow rate can be obtained.
S403, determining an estimated temperature barrier coefficient corresponding to the current third temperature difference and the current second fresh air rate according to the second corresponding relation among the temperature difference, the fresh air rate and the temperature barrier coefficient.
The temperature barrier coefficient in the second corresponding relation is used for representing a temperature difference value of a second indoor temperature and an outdoor temperature of the second room, and a barrier effect of a second fresh air speed of the second fresh air device on a temperature change process of the second room, and the temperature barrier coefficient is a quantitative representation of the barrier effect.
The temperature coefficient of inhibition in the second correspondence may be: the amount of change in temperature of the second room caused by the air introduced into the second room per unit time period; alternatively, the air introduced into the second room from outside the room per unit time period carries heat or cold relative to the temperature in the second room.
The second corresponding relation among the temperature difference value, the fresh air speed and the temperature obstruction coefficient can be stored in a database in a one-to-one correspondence data table mode, and the estimated temperature obstruction coefficient corresponding to the current third temperature difference value and the current second fresh air speed can be obtained by inquiring the database.
Or the second corresponding relation among the temperature difference value, the fresh air rate and the temperature blocking coefficient can be stored in advance in a formula form, and the current third temperature difference value and the current second fresh air rate can be substituted into the formula to obtain the estimated temperature blocking coefficient corresponding to the current third temperature difference value and the current second fresh air rate.
S404, obtaining an estimated temperature interference coefficient difference value of the estimated temperature promoting coefficient and the estimated temperature hindering coefficient.
S405, if the coefficient difference value of the estimated temperature interference coefficient difference value and the historical temperature interference coefficient difference value is smaller than or equal to the minimum set threshold value, determining that the constant temperature interference is maintained in the second room.
In a specific application process, the current second fresh air rate can be regarded as an unknown quantity, and a first expression formed by the current first fresh air rate, the current second fresh air rate and the current second temperature difference (an unknown quantity) represents the promotion effect of the air flowing from the first room to the second room on the temperature change process of the second room; and finally, a formula is formed by the first expression, the second expression, the historical temperature interference coefficient and the minimum set threshold value, so that the formula represents that the second room maintains constant temperature interference.
Solving the formula can obtain one or more current second fresh air rates. The minimum current second fresh air speed can be taken to control the second fresh air device in the second room.
And the historical temperature interference coefficient difference is the difference between the actually estimated temperature promotion coefficient and the actually estimated obstruction coefficient estimated according to the actual first fresh air speed and the actual second fresh air speed before the current moment.
Taking a historical temperature interference coefficient difference value, and substituting the historical temperature interference coefficient difference value into a formula to solve the current second fresh air rate; or taking the average value of a plurality of historical temperature interference coefficients, and substituting the average value of the plurality of historical temperature interference coefficients into a formula to solve the current second fresh air rate.
