摘要： Provided are a space recommendation method, device, and system based on an air conditioning system, and a storage medium, relating to the technical field of space management and the technical field of air conditioners. The method for space recommendation based on the air conditioning system includes: obtaining a user space usage request, wherein the user space usage request carries demand information of a user for a space (S100); determining a current energy consumption amount of each of the plurality of air conditioning units (S200); determining a candidate space based on the current energy consumption amount (S300); and recommending an available space based on the demand information and the candidate space (S400). The space recommendation method, device, and system based on the air conditioning system, and the storage medium solve a problem that energy conservation of the air conditioning system is poor because centralized operation of the air conditioning system is not considered in an existing space recommendation process. Moreover, space recommendation may be performed based on a current energy consumption amount of the air conditioning system. Therefore, user demand is effectively matched with optimization of energy consumption of the air conditioning system, and an energy-saving effect is realized.
