Embodiment Construction
[0030] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary, and embodiments of the present invention are described in detail below.
[0031] In order to solve the problem of the reduction in the number of heating and starting of one-to-many air conditioners, especially the shutdown problem caused by full-on or multi-on to single-on high-voltage alarms, the embodiment of the present invention proposes a control method for one-to-many air conditioners, which can avoid heating The downtime problem caused by the reduction in the number of internal units when starting up improves the comfort of use.
[0032] Refer below figure 1 A method for controlling a one-driver-multiple air conditioner according to an embodiment of the present invention is described.
[0033] One-to-many air conditioners include an outdoor unit and multiple indoor units. Multiple indoor units are connected to the outdoo...

The invention discloses a control method for a multi-split air conditioner, the multi-split air conditioner and a storage medium. The control method for the multi-split air conditioner includes the steps that it is detected that the air conditioner is in a heating mode; it is detected that a compressor operates and the number of started internal units is reduced, the opening of electronic expansion valves of the started internal units is within an initial opening time, a shutdown initial opening is acquired according to the number of online units and the number of started units, and shutdown internal units are controlled to maintain the shutdown initial opening; and after a shutdown initial opening time, the opening of the electronic expansion valves of the started internal units and the opening of electronic expansion valves of the shutdown internal units are controlled according to a target supercooling degree. According to the multi-split air conditioner and the control method thereof, shutdown caused by high pressure warning can be avoided when the number of internal units in heating operation is reduced, and use comfort is provided.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for controlling a one-drag multi-air conditioner, a one-drag multi-air conditioner and a non-temporary computer storage medium. Background technique [0002] At present, as people's demand for the aesthetics and comfort of the living environment continues to rise, the number of room air conditioners is increasing day by day. One-to-many air conditioners have the advantages of flexible installation and reliable use. Explosive growth. [0003] Due to the flexibility of using one-to-multiple air-conditioning indoor units, it is very likely that one indoor unit will be turned on during the user's use. With the increase of medium refrigerant, high-pressure alarm and shutdown problems will occur in many cases, which will affect the comfort of users. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existi...
