The invention provides an air conditioner communication method based on an NB-IoT network. The air conditioner communication method comprises the steps that each air conditioner provided with an NB-IoT module is endowed with a unique identity label; terminals establish communication with a server; the terminals identify the identity labels of the air conditioners; and establish binding relations with the corresponding air conditioners through the server, and the server acquires the binding relation between each terminal and the corresponding air conditioner; each bound terminal is configured to be a unique master control terminal for the corresponding air conditioner; when the air conditioners are in power-on states, the NB-IoT modules in the corresponding air conditioners are connected to the NB-IoT network through a base station; the server is connected to the NB-IoT network through the base station; and when entering the triggering state, the master control terminals output control instructions, and the control instructions are transmitted to the corresponding air conditioners through the server via the NB-IoT network, so as to control the air conditioners to execute actions corresponding to the control instructions. In addition, the invention discloses the air conditioner. Orderly and secure data transmission and control instruction communication processes can be realized.
