METHOD FOR CONTROLLING FLUX OF RADIENT COIL

摘要

A flow control method for a radiant heating coil is provided to prevent non-uniformity of heating operation, overheat, and noise caused due to cavitation when an error has occurred in a valve or excessive amount of hot water is supplied. A flow control method for a radiant heating coil, includes a first step(S10) of inputting a set value of the opening degree of a first valve; a second step(S11) of transmitting a first operating signal corresponding to the set value of the opening degree to the first valve; and a third step(S12,S13) of sensing the opening variation of the first valve in accordance with the first operating signal, and adjusting the degree of opening of a second valve in accordance with the variation of opening of the first valve. The third step includes a step(S16) of transmitting a second operating signal to the second valve if the variation of opening of the first valve is lower than a predetermined level.
