Air conditioner control method and device and air conditioner

Abstract

The invention discloses an air conditioner control method and device and an air conditioner. The method is applied to the air conditioner. The air conditioner comprises a plurality of internal machines. The method comprises the following steps that firstly, a first preset number of internal machines of the plurality of internal machines are obtained as first internal machines, and the other internal machines of the plurality of internal machines except the first internal machine are used as second internal machines; a first total power of all of the first internal machines is then acquired, and then, it is determined whether the first total power exceeds a preset power threshold; when the first total power exceeds the power threshold, the second preset number of first internal machines aredeleted, or the second preset number of first internal machines are deleted, and at least one second internal machine is selected as a newly added first internal machine, wherein a total power of allthe newly added first internal machines is less than the power threshold; and finally, the current all first internal machines are controlled to maintain a running state, and the other internal machines except the current first internal machines are kept in a closed or standby state. According to the scheme, the air conditioner can improve the connection rate of the air conditioner while guaranteeing reliability of the air conditioner.

Description

technical field [0001] The present invention relates to the technical field of air conditioner control, in particular to an air conditioner control method, device and air conditioner. Background technique [0002] The connection rate of the indoor unit of the air conditioner, that is, the ratio of the total capacity of the internal unit to the capacity of the external unit. For air conditioners, air conditioners from different manufacturers have different connection ratios. Within the limited range of the connection ratio of the air conditioner, keeping the air conditioner at a higher connection ratio can improve the cooling or heating effect of the air conditioner. [0003] For a multi-connection system, there will be situations where multiple internal units will be turned on, so that the connection rate of the multi-connection device will exceed the upper limit, and the connection rate of the multi-connection device will exceed the upper limit, which will lead to poor work...
