The rotating speeds of compressors, water pumps and fans are adjusted via frequency converters to achieve precise temperature control and energy-saving optimization. Nevertheless, the complete system is a typical multi-equipment non-linear load: frequent start-stop day and night, large-amplitude load variations caused by seasonal temperature changes and passenger-flow fluctuations; heavy harmonic superposition due to concurrent operation of multiple inverters; densely-arranged equipment inside machine rooms with limited heat dissipation, which easily leads to overheating and overload of ordinary electrical devices.
