Central air conditioning is a big power consumer in the building. In the annual electricity charge, the power consumption of air conditioning can reach about 60% of that of the whole building. The central air conditioning system in the building is designed and installed according to the maximum load with a certain margin. In a year, it only runs for more than one month or even more than ten hours under full load, and the load is less than 70% most of the time. In general, the load of the refrigeration unit in the central air conditioning system can automatically adjust the load with the change of the seasonal temperature. However, the refrigeration pump and cooling pump matching with the refrigeration host can not automatically adjust the load, which almost runs under 100% load for a long time, which results in a great waste of energy and deteriorates the operating environment and quality of central air conditioning.

Product advantages
1. Advanced technology platform - all series of products are developed and applied based on the high-performance speed sensorless vector control technology platform, which is synchronized with the current international leading technology.
2. Remarkable energy-saving effect - vector control technology is adopted, which is efficient and energy-saving, with high return on investment, which is especially suitable for the energy-saving transformation project of central air-conditioning.
3. Good cooling effect - perfect independent cooling air duct design, the cooling fan can be easily disassembled, easy to maintain; independent design of air duct, better dust-proof, anti-corrosion effect, strong adaptability to the environment.
4. Super load capacity - the starting torque can reach 180% of rated torque output; under any acceleration and deceleration time and any instantaneous impact load conditions, the inverter operates stably without tripping, which is safe and stable.
5. Power frequency / frequency conversion control switching - integrated energy saving control cabinet can realize power frequency / frequency conversion control switching; Y - △ switching start is supported during power frequency operation, which is convenient for equipment maintenance and inverter maintenance.
6. It is convenient to realize constant temperature control - the frequency converter has built-in mature and efficient PID control algorithm, which can quickly respond to the requirements of air conditioning temperature conversion, so as to realize constant temperature and power saving control.
7. Low electromagnetic noise - the frequency converter adopts the wide carrier frequency regulation technology up to 16K and the automatic carrier control technology, which can automatically adapt to the load and module temperature changes and change the carrier frequency to continue to operate, find the balance point of carrying capacity and noise tolerance, fully reduce the motor noise, and realize the industrial level mute control.
