Description

technical field [0001] The present invention relates, in particular, to a magnetic levitation central air conditioner, and more specifically, to a magnetic levitation multi-head central air conditioner load distribution system and method. Background technique [0002] At present, magnetic levitation refrigeration compressors are widely used in central air conditioners, for example, as disclosed in Chinese patent authorization announcement number CN201502503U. The magnetic levitation refrigeration compressor is supported by a magnetic levitation bracket. There is no physical contact between the rotor and the bracket due to the magnetic force, and the rotation of the rotor does not have any mechanical friction, thereby reducing energy consumption and improving the performance of the motor. It not only improves the efficiency, but also further Energy is saved. [0003] At present, multi-module units are used in air conditioners. By judging the cumulative running time of each c...

Problems solved by technology

However, the existing load distribution is based on the load demand, comprehensively considering the running time and energy state of the compressor, directly controlling the loading and unloading of the compressor, whether the actual load of the compressor reaches the distributed load, and the maximum capacity of the compressor. Optimum operating condition without adequate consideration

This causes overshooting of the compressor, causing frequent start-stop and large-scale loading and unloading of the compressor, which has a great impact on improving the energy efficiency of the compressor, optimizing operating costs, and prolonging the service life of the compressor.
