Heating Ventilation Air Conditioning｜Central air conditioning Case
Central air conditioning systems are core heating and cooling equipment for commercial complexes, office buildings, industrial plants and large scale venues. They mainly consist of variable frequency water chillers, cooling water pumps, chilled water pumps and fans. Frequent start stop operations and variable frequency speed regulation bring drastic dynamic load fluctuations, which readily generate high frequency harmonics, transient inrush currents and voltage fluctuations. These may result in overheating of main unit compressors, damage to variable frequency modules, jitter of pipe network water pumps and abnormal meter readings. Special purpose transformers and reactors for central air conditioning serve as indispensable power quality protection components for HVAC variable frequency systems. They realize functions including stabilized power supply, harmonic governance, inrush current limiting and motor protection. Custom developed for long term non stop operation, multi equipment parallel connection and drastic diurnal load fluctuation conditions of HVAC systems, our products feature lower losses, stronger harmonic resistance and quieter operation compared with general purpose industrial products. They resolve industry pain points such as high electric control failure rates, excessive energy consumption and unstable operation of central air conditioning, and guarantee year round stable and energy saving operation of HVAC systems.
