The fresh air rate relationship is a magnitude relationship between a first fresh air rate of a first fresh air device in the first room and a second fresh air rate of a second room, and under the condition that the first fresh air device operates according to the first fresh air rate and the second fresh air device operates according to the second fresh air rate, the first pressure of the first room is higher than the second pressure of the second room.
The quantity of the preset temperature intervals is the same as the quantity of the fresh air rate relation; the number of the preset temperature intervals is more than two, and the number of the fresh air speed relations is more than two.
Optionally, determining a current fresh air rate relationship corresponding to the current temperature interval according to a corresponding relationship between the temperature interval and the fresh air rate relationship, including:
under the condition that the current temperature interval is a first temperature interval, determining that the current fresh air rate relation corresponding to the current first temperature interval is a first fresh air rate relation;
under the condition that the current temperature interval is a second temperature interval, determining that the current fresh air rate relation corresponding to the current second temperature interval is a second fresh air rate relation;
the minimum value in the first temperature interval is greater than or equal to the maximum value in the second temperature interval, and under the condition that the fresh air rate of the first fresh air device and the fresh air rate of the second fresh air device are in a corresponding relation of the first fresh air rate, the first pressure of the first room is greater than the second pressure of the second room; and under the condition that the fresh air rate of the first fresh air device and the fresh air rate of the second fresh air device are in the corresponding relation of the second fresh air rate, the third pressure of the first room is higher than the fourth pressure of the second room, and the pressure difference value between the first pressure and the second pressure is higher than the pressure difference value between the third pressure and the fourth pressure.
The current first temperature difference value is in the first temperature interval, which indicates that the current first temperature difference value is larger, in this case, the pressure difference value between the first pressure of the first room and the second pressure of the second room is made larger, so that more air can flow into the second room from the first room, the more air flow improves the heat exchange between the first room and the second room, the current second temperature difference value is larger, and compared with the second room, the larger the influence of the temperature change of the second room on each unit of air flowing into the second room from the first room, the more the current first temperature difference value between the current first room temperature and the current second room temperature can be reduced more quickly.
The number of the preset temperature intervals is multiple, and under the condition that the number of the preset temperature intervals is two, the first temperature interval and the second temperature interval are two continuous temperature intervals; in the case where the number of the preset temperature intervals is three or more, the first temperature interval and the second temperature interval may be two continuous temperature intervals or two discontinuous temperature intervals. For example, the preset temperature interval is a temperature interval a, a temperature interval B and a temperature interval C, and the temperature interval a, the temperature interval B and the temperature interval C are sequentially continuous in the order of the temperature from high to low; in this case, if the first temperature section is the temperature section a, the second temperature section may be the temperature section B or the temperature section C, and if the first temperature section is the temperature section B, the second temperature section is the temperature section C.
S205, determining a current first fresh air rate and a current second fresh air rate which meet the current fresh air rate relation.
For example, the current first fresh air rate and the current second fresh air rate that satisfy the current fresh air rate relationship may be determined as follows: firstly, obtaining the current outdoor pressure of the outdoor environment; determining the current second pressure of the second room according to the current outdoor pressure, wherein the pressure difference value between the current second pressure and the current outdoor pressure is greater than or equal to the set minimum pressure threshold; determining a second current fresh air rate according to the current second pressure, wherein the current second pressure and the current second fresh air rate have positive correlation; and determining a current first fresh air rate corresponding to the current second fresh air rate according to the current fresh air rate relation.
Under the condition of adjusting the indoor air freshness by sucking fresh air into a room, the indoor pressure is usually stronger than the outdoor pressure, and a person skilled in the art can determine the minimum set pressure threshold value according with the actual situation according to experience.
Or, the current first fresh air rate and the current second fresh air rate which satisfy the current fresh air rate relationship can be determined by the following method:
obtaining a current second temperature difference value between the current second indoor temperature and the current outdoor temperature; determining a current second fresh air rate corresponding to the current second temperature difference according to the negative correlation relationship between the temperature difference and the fresh air rate; determining a current first fresh air rate corresponding to a current second fresh air rate according to the current fresh air rate relation; and the current second fresh air rate is greater than or equal to the first minimum fresh air rate threshold value.
Under the condition that the fresh air speed of air sucked into the second room from the outside is not changed, the larger the difference value of the current temperature of the second room and the outdoor environment is, the larger the blocking effect of each unit of air sucked into the second room from the outside on the change process of the current second indoor temperature of the second room is.
The greater the rate of air being drawn into the second room from the outside, the greater the obstruction to the process of change of the current second indoor temperature of the second room, with the current second temperature difference between the current second indoor temperature and the current outdoor temperature being constant.
Making the temperature difference inversely related to the fresh air rate, then: the larger the current second temperature difference is, the smaller the current second fresh air rate is; the smaller the current second temperature difference is, the larger the current second fresh air rate is. The current second fresh air rate is adjusted in such a way, so that the air sucked into the second room from the outside can maintain stability to a certain degree for the hindering effect of the current second indoor temperature of the second room on the change process.
Alternatively, determining the current first fresh air rate and the current second fresh air rate that satisfy the current fresh air rate relationship may include:
obtaining a current third temperature difference value of the current first indoor temperature and the current outdoor temperature; determining a current first fresh air rate corresponding to the current third temperature difference according to the negative correlation relationship between the temperature difference and the fresh air rate; determining a current second fresh air rate corresponding to the current first fresh air rate according to the current fresh air rate relation; and the sum of the current first fresh air speed and the second fresh air speed is greater than or equal to a second minimum fresh air speed threshold value.
Under the condition that the fresh air rate of the air sucked into the first room from the outside is not changed, the larger the difference value of the current third temperature between the first room and the outdoor environment is, the larger the obstruction effect of the current first indoor temperature change process of the first room on each unit of air sucked into the first room from the outside is.
The greater the rate of air being drawn into the first room from the outside, the greater the resistance to the course of change of the current first indoor temperature of the first room, with the current third temperature difference between the current first indoor temperature and the current outdoor temperature being constant.
Making the temperature difference inversely related to the fresh air rate, then: the larger the current third temperature difference is, the smaller the current first fresh air speed is; the smaller the current third temperature difference value is, the larger the current first fresh air rate is. The current first fresh air speed is adjusted in such a way that the air sucked into the first room from the outside can maintain stable to a certain extent in the blocking effect on the change process of the current first indoor temperature of the first room.
Further, the factors that affect the current first indoor temperature of the first room include: the temperature adjusting device of the first room adjusts the indoor temperature of the first room, and air having a temperature different from the current first indoor temperature is sucked into the first room from the outside. Because the above technical solution can make the air sucked into the first room from the outside maintain stable to a certain extent, the main influencing factor of the current first temperature of the first room is the regulating action of the temperature regulating device on the indoor temperature of the first room, that is, in the regulating process of the temperature regulating device on the indoor temperature of the first room, the external interference is the influence of the air sucked into the first room from the outside, and the interference is relatively stable interference, so that in the regulating process of the indoor temperature of the first room, after the indoor temperature of the first room first reaches the set temperature, the indoor temperature of the first room can be relatively quickly stabilized at the set temperature.
In the application process of the linkage fresh air device provided by the embodiment of the application, the temperature difference value between the current first indoor temperature and the set temperature of the first room is smaller than the temperature difference value between the current second indoor temperature and the set temperature of the second room, so that the requirement of the temperature regulation process of the first room on stable regulation is greater than the requirement of the temperature regulation process of the second room on stable regulation; the demand for quick adjustment by the temperature adjustment process of the second room is greater than the demand for quick adjustment by the temperature adjustment process of the first room.
The influencing factors on the current second indoor temperature of the second room include: the temperature control device of the second room controls the indoor temperature of the second room, air sucked into the second room from the outside and having a temperature different from the current second indoor temperature, and air flowing into the second room from the first room. By adopting the adjusting method of the linkage fresh air device provided by the embodiment, the first pressure of the first room is higher than the second pressure of the second room, the air in the first room can carry certain cold/heat to flow into the second room, and the temperature adjusting process of the second room is accelerated.

In the case where the first room and the second room are simultaneously warmed, the air with a higher temperature in the first room can be made to flow into the second room, and the heat of the first room can flow into the second room, such a flow of heat can reduce the temperature difference between the first indoor temperature of the first room and the second indoor temperature of the second room; in the case where the first room and the second room are simultaneously cooled, the air whose temperature is reduced in the first room can be made to flow into the second room, and the cooling energy of the first room can be made to flow into the second room, and such flow of the cooling energy can reduce the temperature difference between the first indoor temperature of the first room and the second indoor temperature of the second room.
