The invention discloses a multi-split air conditioner control method and device and a multi-split air conditioner. The method comprises the steps that the lumped room temperature of a building where the multi-split air conditioner is located in past first preset time is determined, and the lumped room temperature reflects the heat storage state of the building; determining a lumped room temperature change interval according to the current set temperature of each indoor unit; acquiring meteorological data of the area where the air conditioner is located in future second preset time; according to the lumped room temperature and the meteorological data in the past first preset time, the lumped room temperature change interval, the meteorological data in the future second preset time and the air conditioner energy consumption at the current moment, a lumped room temperature sequence in the future second preset time is solved, and the total energy consumption of the air conditioner in the future second preset time is made to be minimum; and the lumped room temperature sequence in the second preset time in the future serves as a set temperature sequence in the second preset time in the future, and the air conditioner is controlled to operate. Under the condition of ensuring that the room temperature is in a comfortable range, the total energy consumption in the future air conditioner operation period is minimized by utilizing the heat storage potential of the building.
Description
technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a method and device for controlling a multi-connected air conditioner, and a multi-connected air conditioner. Background technique [0002] The operating energy efficiency (COP) of an air conditioner refers to the ratio of the heating / cooling capacity (or heating / cooling power) of the air conditioner to the energy consumption (or electric power) of the air conditioner, and is an important parameter used to evaluate the energy saving performance of the air conditioner. [0003] The multi-connected air conditioner is an air conditioning system with one drive and multiple units (that is, one outdoor unit corresponds to multiple indoor units), which can adjust the room temperature of multiple rooms. At present, the energy-saving optimization of multi-connected air conditioners is mainly realized by optimizing the COP. For example, according to the local climate char...
