The invention has the beneficial effects that: according to the method, the target building BIM model data can be obtained, the target building can be accurately divided by using the BIM model data, the target areas can be in units of rooms according to actual conditions, and because adjacent target areas are the same or similar in temperature demand intervals possibly due to similar functions or similar demands, the target areas with the same temperature demand intervals can be combined to obtain a same-temperature area group, and then fresh air paths are set for the same-temperature area group, so that the influence of fresh air on the indoor air conditioner temperature can be avoided, and unnecessary loss of an air conditioner is reduced. Moreover, the method is also applicable to the field of the present invention. Compared with the scheme of directly carrying out fresh air treatment on the whole target building, the method has the advantages that the total length of each independent fresh air path is greatly reduced, so that the wind energy loss is reduced, and the effective rate of fresh air power is improved;
the foregoing describes one embodiment of the present invention in detail, but the disclosure is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. All equivalent changes and modifications within the scope of the present invention are intended to be covered by the present invention.
