The invention discloses a method for controlling a one-to-multiple air conditioner, a one-to-multiple air conditioner and a storage medium, wherein the control method of a one-to-multiple air conditioner includes: detecting that the air conditioner is in a heating mode; detecting that the compressor is running and starting the The number of internal units is reduced, and the opening of the electronic expansion valve of the internal unit is within the initial opening time, and the initial opening of the shutdown is obtained according to the number of connections and the number of startups, and the shutdown initial opening is controlled to maintain the shutdown initial opening; After the time, according to the target subcooling degree, control the opening of the electronic expansion valve of the internal unit when starting up and the opening of the electronic expansion valve when shutting down the internal unit. The one-drive-multi-air conditioner and the control method thereof of the present invention can avoid shutdown caused by high-pressure alarm when the number of internal units in heating operation is reduced, and provide comfort in use.
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...
