A central air conditioner includes: a plurality of air cooling modules in which one or more compressors are arranged; the plurality of waterway terminals are respectively in fluid connection with the air cooling module; the cloud control platform is in communication connection with the air cooling module and is configured to execute one or more of the following operations: acquiring the working states of the plurality of waterway terminals; predicting and calculating the output rate of the air cooling module matched with the external thermal load; and according to the predicted and calculated output rate of the air cooling module, the air cooling module put into operation is determined, and the number of available compressors put into operation is controlled so that the total refrigerating capacity and the external thermal load can be synchronously increased, decreased and matched. Based on the cloud control platform, the number of the air cooling modules needing to be put into operation and the number of the available compressors can be adjusted at any time along with changes of external loads, the refrigerating capacity of the unit and the external heat loads are synchronously increased and decreased to achieve optimal matching, and the unit always operates at the optimal efficiency.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to central air conditioners. Background technique [0002] In recent years, central air-conditioning systems with low energy consumption, environmental protection requirements and intelligent operation are generally required in emerging urban buildings (especially high-rise buildings). The design of the central air-conditioning system and the optimal selection and precise control of supporting equipment are inseparable and complement each other. [0003] Represented by the air-cooled modular unit, the wired network and wireless network functions of the existing central air conditioners only realize the remote detection and control of the unit, and can only control the switch, working mode and temperature setting of the unit to complete the basic functions. Conventional control is still realized by the built-in processor of the unit itself. The computing power of the local...
