Compared with the prior art, the invention has the following advantages: with the improvement of living standard, people pay more and more attention to the harm of air pollution to health. The haze which is frequently generated enables people to recognize the important significance of the air ventilation equipment. In view of the great market potential of current air exchange devices, several air exchange devices or methods of controlling the same have been developed in the prior art. For example, CN103148560B in the prior art proposes a method for monitoring indoor air pollution and ventilation control, which basically realizes automatic start and stop and automatic control of air ventilation equipment, and generally realizes control of a household air purifier. However, the prior art has the following problems: this prior art control method assumes at least one ventilator in each room, which is not true at least for the following cases: for a common family, one family only has one or two air purifiers, and each room cannot be guaranteed to have a purifier; for an office building, tenants may place a simple separation of the rented space as a separate office.

means for sending, by the central control device, a second instruction to the air exchange device in the first semi-enclosed space to operate the air exchange device in the first semi-enclosed space at a second power higher than the first power for a second time if the re-sensed contaminant concentration in the first semi-enclosed space is still greater than the threshold value,
the device further comprises: a plan view of the entire space is stored in the central control device, and wherein the predetermined sequence is randomly generated by the central control device, the predetermined sequence describing a correspondence between each air quality sensor and each semi-enclosed space,
the device further comprises:
means for searching, by the central control device, for a ventilator closest to the first semi-enclosed space if no ventilator is present in the first semi-enclosed space; and
means for sending, by the central control device, a third instruction to an air mover nearest the first semi-enclosed space to operate the air mover nearest the first semi-enclosed space at a third power for a third time, wherein the third power is higher than the first power and the third time is longer than the first time.
