And the user not only has the needs to indoor temperature, and also has certain needs to the freshness of indoor air, and accessible new trend device is with outdoor air supply in a room, for this room provides fresh air to improve the freshness of the air in this room.

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 indoor temperatures of the two rooms are not likely to be stabilized at the set temperature relatively quickly due to the influence of the heat exchange amounts of the two rooms.

If the first room is in the temperature rise process, the air with the lower temperature in the first room flows into the second room, and then the air with the higher temperature is led into the first room from the outside, so that the current first indoor temperature of the first room is increased quickly, and the electric energy required by the temperature adjusting device in the first room is reduced.
If the second room is in the cooling process, the air with higher temperature in the first room flows into the second room, and then the air with lower temperature is introduced to the first room from the outside, so that the current first indoor temperature of the first room is reduced quickly, and the electric energy required by the temperature regulating device in the first room is reduced.
And reducing the pressure difference value between the third pressure in the first room and the fourth pressure in the second room along with the further reduction of the current first temperature difference value, so that the speed of air flowing from the first room to the second room is slower, and the speed of cold or heat flowing from the first room to the second room is also slower. Like this, the temperature control model in first room is more stable, and the temperature control model in second room is also more stable, and then, is favorable to the present first indoor temperature in first room to stabilize at the settlement temperature relatively fast to and, be favorable to the present second indoor temperature in second room to stabilize at the settlement temperature relatively fast.

In the test process, the pressure difference between the first room and the outdoor environment and the pressure difference between the second room and the outdoor environment are required to be kept, and the conventional requirements are met.
The corresponding relation between the temperature difference and the fresh air speed and the corresponding relation between the temperature interval and the fresh air speed can be pre-stored in a database in a one-to-one correspondence data table mode, and after the current first temperature difference or the current temperature interval is obtained, the current first fresh air speed corresponding to the current first temperature difference can be obtained by inquiring data, or the current first fresh air speed corresponding to the current temperature interval can be obtained.

After the first fresh air device is controlled according to the current first fresh air rate and the second fresh air device is controlled according to the current second fresh air rate, the current first pressure of the first room can be larger than or equal to the current second pressure of the second room, and then the heat or the cold of the first room can flow to the second room.
When the current first indoor temperature is lower than the set temperature and the current second indoor temperature and the current outdoor temperature are higher than the set temperature, or when the current first indoor temperature is higher than the set temperature and the current second indoor temperature and the current outdoor temperature are lower than the set temperature, fresh air is introduced into the first room through the first fresh air device, on one hand, the fresh air device has a promoting effect on the change of the current first indoor temperature of the first room to the set temperature, the change rate of the current first indoor temperature to the set temperature is increased, the time required for the indoor temperature of the first room to reach the set temperature from the current first indoor temperature is shortened, in addition, the electric energy consumed by the air conditioner for adjusting the indoor temperature of the first room to the set temperature from the current first indoor temperature can be reduced, on the other hand, the current first pressure of the first room is higher than or equal to the current second pressure of the second room, in addition, heat flow exists between the first room and the second room, the heat or the cold flow in the first room is favorably into the second room, and the rate of the indoor temperature of the second room to reach the set temperature from the current second indoor temperature is increased.

The preset difference value is used for representing a pressure difference value of a first pressure of the first room and a second pressure of the second room, further representing air flow rates of the first room and the second room, and further representing heat flow rates of the first room and the second room.
The number of the preset difference values is the same as the number of the corresponding relations of the fresh air speed and the number of the preset temperature intervals.
Intuitively, each preset difference value may be analogous to a "shift" of the heat flow rate, with a plurality of preset difference values corresponding to a plurality of "shifts" of the heat flow rate, and each preset temperature interval corresponding to a "shift". And therefore, the heat flow rate of a lower 'gear' can be determined under the condition that the current first temperature difference value is smaller, and a target difference value can be further determined from a plurality of preset difference values.
This process of confirming new trend speed corresponding relation is the process of confirming a new trend speed corresponding relation, and this new trend speed corresponding relation corresponds with a temperature interval of predetermineeing.

And S305, determining a second fresh air rate according to the product of the second ratio and the second volume.
For example, the second fresh air rate may be the product of the second ratio and the second volume. Or, in consideration of actual conditions, the product of the second ratio and the second volume is subjected to fine adjustment, and the fine adjustment result is used as the second fresh air rate. The manner of fine tuning includes increasing the product and decreasing the product.
The first fresh air rate is used for controlling the fresh air rate of the first fresh air device, and the second fresh air rate is used for controlling the fresh air rate of the second fresh air device.
According to the mode, the corresponding relation of the fresh air speed can be determined. The number of the fresh air rate corresponding relations is the same as the number of the preset temperature intervals, and a person skilled in the art can execute the process for multiple times according to the number of the preset temperature intervals so as to obtain the fresh air rate corresponding relation corresponding to each preset temperature interval, and further obtain the current fresh air rate corresponding relation according to the current temperature interval, and further determine the current second fresh air rate, so that the control of a second fresh air device in a second room is realized.
After the current second fresh air rate is obtained, the second fresh air device is enabled to directly operate according to the current second fresh air rate, or the current second fresh air rate can be finely adjusted, so that the second fresh air device operates according to the adjusted second fresh air rate.

Furthermore, the current second indoor temperature is out of the temperature range defined by the set temperature and the current outdoor temperature, which indicates that the temperature difference between the current second indoor temperature and the set temperature is large, and at the moment, the current second fresh air rate is increased, so that the current second indoor temperature can change to the set temperature relatively quickly;
the current second indoor temperature is within the temperature range defined by the set temperature and the current outdoor temperature, and the temperature difference between the current second indoor temperature and the set temperature is smaller, so that the current second fresh air speed is reduced. Considering the situation of the first room, if the temperature difference between the current first indoor temperature and the set temperature is large, the current first fresh air rate is large, the current second fresh air rate is reduced, the pressure difference between the first pressure of the first room and the second pressure of the second room can be improved, the heat of the first room can flow to the second room more quickly, and the temperature difference between the current first indoor temperature and the set temperature can be reduced as soon as possible; if the temperature difference between the current first indoor temperature and the set temperature is small, the current second fresh air speed is reduced when the current first fresh air speed is small, the pressure difference between the first pressure of the first room and the second pressure of the second room can be reduced, the flow speed of heat in the first room flowing to the second room can be reduced, the temperature control model in the first room and the temperature control model in the second room are more stable, and the current first indoor temperature and the current second indoor temperature can be stabilized at the set temperature more quickly.
