Air conditioning water system variable frequency variable flow technology

The cooling load of the central air conditioner changes with the change of the ambient temperature and the use area. The water pump motor of the fixed flow water system basically runs at full load, forming a phenomenon of large flow and small temperature difference, for the case of low efficiency and high energy consumption. The air conditioning water system frequency converter is used to control the operation of the chilled water pump motor, so that the flow rate of the chilled water is proportional to the cold load, and a good energy saving effect is obtained, and the economic benefit is remarkable. When selecting the frequency converter, the capacity of the motor power is mainly considered, and factors such as high reliability, easy operation, and reasonable price are also considered. After 30 years of technological innovation, the development of frequency converter has become the mainstream of motor speed control, playing an important role in various industries, and with the development of the full digital control mode of the frequency converter, its high precision and reliability. High, stable, storage, and logical computing capabilities will be more prominent, economic benefits will be more significant, and the scope of application will be more extensive.
