| 摘要 |
The present invention relates to a system for removing scales and controlling a temperature of a heat exchanger, which selectively controls the heat exchange of a heat exchanger in the winter or in the summer by installing an electric ball valve for controlling the flow of cooling water, and effectively removes scales from the heat exchanger or prevents the scales from sticking to the heat exchanger by reducing back pressure applied to the heat exchanger and a recovery pipe to maximize the operation of an air injection device. |
