Máy ESI - B500Y- Giải pháp tiết kiệm năng lượng

Product Introduction:

Ensave B500Y Series Smart Centralized Air-condition system is safe and reliable. It not only has overload protection, failure bypass protection function, but also stabilizes the voltage, suppress over-voltage fluctuation amplitude, reduce network losses, improve power factor, and improved power efficiency, which brought great convenience to the user.

Principle of Ensave Energy saving system for Centralized Air Condition

The operating principle of the water pump and fan of fluid transmission equipment is that, the flow (air quantity) of the water pump and fan is in direct proportion to their rotation speed. The pressure (head) of the water pump and fan is in direct proportion to the square of their rotation speed. The shaft power of the water pump and fan is equal to the product of the flow and pressure, so the shaft power of the water pump and fan is in direct proportion to the cube of their rotation speed (that is, in direct proportion to the cube of the power frequency). Based on the above principle, if the rotation speed of the water pump and fan is reduced, the power of the water pump and fan can be reduced to a greater extent.

For example, if the power frequency is reduced from 50Hz to 45Hz, P45/P50=(45/50)3=0.729. That is, P45=0.729P50 (P stands for the shaft power of the motor); if the power frequency is reduced from 50Hz to 40Hz, P40/P50=(40/50)3=0.512, that is, P40=0.512P50 (P stands for the shaft power of the motor).
