A system for controlling expansion water and supplementary water of a parallel circulation system is provided to control the expansion water and the supplementary water of one circulation system by using an expansion tank and a water processing unit included in the other circulation system. A system for controlling expansion water and supplementary water of a parallel circulation system includes a first circulation system(10), a second circulation system(20), an expansion water pipe(30), a supplementary water pipe(40), a first valve unit(50), and a second valve unit(60). The water expanded from a first circulation pipe is discharged to a second circulation pipe through the expansion water pipe. The supplementary water is supplied from the second circulation pipe to the first circulation pipe through the supplementary water pipe. The first valve unit controls the flow of the water supplied through the expansion water pipe. The second valve unit controls the flow of the water supplied through the supplementary water pipe. |
