CIRCULATION TYPE REHEAT SYSTEM FOR OBTAINING DISCHARGE TEMPERATURE VERY CLOSE TO PRESET TEMPERATURE IN ELECTROMAGNETIC INDUCTION HEAT GENERATION TYPE FLUID HEATING SYSTEM

摘要

PROBLEM TO BE SOLVED: To solve the problem of an electromagnetic induction heat generation type fluid heating system, wherein in the case of setting the system as an IH instantaneous water boiler, immediately after a valve is opened, hot water having a temperature lower than the required set temperature is discharged for a while, so it is necessary to set a correct required set temperature from the first.;SOLUTION: This circulation type reheat system is added to the heating system, whereby a temperature closer to the required set temperature can be stably taken out. Although the electromagnetic heat induction heat generation type fluid heating unit has enough output during normal operation, in order to discharge hot water having a correct temperature from the moment when the discharge control valve is opened, water is once circulated and reheated, and when the final sensor outputs a correct temperature, the discharge control valve is regulated to discharge hot water. Thus, hot water having a correct required set temperature can be stably taken out.;COPYRIGHT: (C)2003,JPO
