ある。The isothiazoline compounds and bromine compounds used in the present invention have antibacterial properties, and simply adding a small amount to brine solves various problems such as foul odors and corrosion caused by putrefying organic substances. Furthermore, since it has extremely low metal corrosivity, it is very advantageous in terms of preventing rust. Therefore, the brine containing the isothiazoline compound and the bromine compound of the present invention can be used for a long period of time and does not corrode the metals constituting the refrigeration equipment and cooling equipment, thereby improving the durability of the equipment. Furthermore, it is useful for improving the working environment.
