A and B are both constant coefficients.
After that, one indoor unit in the operating state is determined as the master according to the usage amount of each indoor unit in the operating state, and specifically, the indoor unit with the highest usage amount may be used as the master.
In determining the host, in consideration of the possibility that the indoor unit determined as the host has no person in its room at this time, in order to ensure the user's use experience, it is preferable to set the indoor unit in the room where the person is present as the host. Thus, the present example provides a preferred implementation, namely: determining the indoor unit with the highest usage amount according to the usage amount of each indoor unit in the running state; judging whether personnel exist in the room where the indoor unit with the highest usage amount is located (or judging whether the room has personnel in a last preset time period so as to exclude the special case that the personnel temporarily and temporarily leave). If yes, determining the indoor unit with the highest usage amount as a host; if not, further judging whether personnel exist in the room where the indoor unit with the next highest usage amount exists, and the like until the host is determined. Therefore, the indoor unit in the room where the person is located can be ensured to be set as the host, and the switching and adjustment of the working mode of the host by the user at any time are facilitated.
After the master and the slave are determined, the identity of the master or the slave of each indoor unit can be displayed through a display screen, and information for determining the master is sent to a user. The computer can receive the control information of the user and switch the working mode according to the control information. The slave can also switch to an operating mode in which there is no conflict with the master. Thereby avoiding the situation of conflict between the working modes of different indoor units in the multi-split system to the maximum extent. And the use experience of the user is improved.
