FEEDBACK CONTROL SYSTEM FOR SHEDDING FREQUENCY OF HEAT EXCHANGER

摘要

PURPOSE: A feedback control system for shedding frequency of heat exchanger is provided to maximize heat transfer efficiency by expanding turbulence of heat transfer medium. CONSTITUTION: A system includes a detector(12) installed to a heat exchanger(10) to detect flowing quality of heat transfer medium; a frequency calculating part(14) analyzing flowing quality detected by the detector to calculate shedding frequency of the heat transfer medium; and a pulse providing device providing pulse with a period same with shedding frequency calculated by the frequency calculating part to the heat transfer medium of the heat exchanger.
