How does air-cooled variable frequency control the rotation speed by adjusting what?
Thread Content
The operator controls the speed of the air cooler by increasing or decreasing the opening degree of the variable-frequency control valve for air cooling. However, on-site, it seems that the air cooler with variable-frequency control isn’t any different from the others; a colleague said it is controlled by increasing or decreasing the current. Is that really the case?
Frequency conversion involves adjusting the current frequency in order to control the motor speed, thereby regulating the outlet temperature of the air cooling system and achieving energy savings.
Air-cooled variable frequency cooling is achieved by using a variable-frequency motor to adjust the motor current, thereby changing the motor speed and consequently the volume of cooling air, and thus altering the amount of cooling provided
Search, are metering pumps with variable frequency also controlled by changing the motor current?
