Networking equipment group and air conditioning system

The invention discloses a networking equipment group and an air conditioning system. Wherein the equipment group capable of networking comprises a plurality of pieces of equipment, the orientation of a communication port on each surface of the equipment serving as an original point is consistent with a real physical orientation, and the relationship between the communication port on each surface and a predefined axial direction is consistent with a predefined relationship; the rest devices are connected in series through cables to form N paths of device groups, and the N paths of device groups are respectively connected to each communication port of the original point; during networking, starting from the original point, each device in the device group sequentially serves as a receiving node to receive networking information sent by the sending node, and the space coordinates of each receiving node and the real physical orientation of each communication port of the receiving node are calculated according to t
