Kinda VFD Frequency Converterr Applied In Pumps And Fans 380V

1, Load feature
(1) Both of them belong to fluid control.
(2) If without VFD, the fluid is controlled by valve or baffles;
(3) For less fluid required system, there will be more energy saving.
(4) In theory, if the running frequency is H1, then Energy Saving = 1-(H1/50)3

2, Requests for frequency inverters (VFD)
(1) Soft start the motor, reduce the surge current.
(2) VFD should work continuously without fault.
(3) Speed tracking and start (flying start) function should be reliable.
(4) In some systems, PID function is required.

3, Real example
In a hotel, there is an central air-conditioner, the cooling fan is one PCS of 15kW motor, in one year,
it runs 4000h, 2000h with the air flow of 85%, 2000h with the air flow of 60%.
