INDOOR FAN CONTROL DEVICE AND A METHOD OF A DUCT FOR VARYING AND DISCHARGING THE FLOW OF THE AIR IN COMPARISON TO STATIC PRESSURE OF A WIDE RANGE BY CONTROLLING AN INVERTER WITH FREQUENCY CORRESPONDING TO CURRENT STATIC PRESSURE AND THE FLOW OF THE AIR
INDOOR FAN CONTROL DEVICE AND A METHOD OF A DUCT FOR VARYING AND DISCHARGING THE FLOW OF THE AIR IN COMPARISON TO STATIC PRESSURE OF A WIDE RANGE BY CONTROLLING AN INVERTER WITH FREQUENCY CORRESPONDING TO CURRENT STATIC PRESSURE AND THE FLOW OF THE AIR
Purpose: indoor fan control equipment and a kind of method for a conduit are arranged to adjust the flowing of the air in real-time wide static pressure situation and energetically deal with static pressure condition, are varied widely according to live mounting condition by with one indoor fan of a Driven by inverter. Construction: an indoor fan controls equipment, for having a motor (33) of an inverter (32) to drive an indoor fan (34) for a conduit by control, including a storage device (36), it is used to remember the necessary air-flow of each static pressure for determining by test; For detecting a static pressure sensor (37) of current static pressure; One inverter drive unit (35) is used to determine working frequency according to the flow of requirement of the corresponding air of current with storage device is maintained at static pressure, when the current static pressure detected by static pressure sensor, which is changed, then controls inverter by determining working frequency.
