Brine supply unit

A brine supply unit for supplying brine to at least one load after controlling the temperature of the brine so as to meet a target temperature of the load, comprising:

• a heat exchanger disposed at a brine-cooling channel through which the brine returned from the load flows, for cooling the brine with water for industrial use;
• a heater disposed at a brine-heating channel formed in parallel with the brine-cooling channel, through which the brine returned from the load flows, for heating the brine;
• a mixing section disposed at a connecting portion between the brine-cooling channel and the brine-heating channel, for mixing the brine cooled with the heat exchanger and the brine heated with the heater;
• a mixing-section-outlet-side temperature sensor disposed at the outlet of the mixing section for measuring the temperature of the brine from the mixing section;
• a mixing control unit for controlling the mixing ratio of the brine cooled with the heat exchanger and the brine heated with the heater on the basis of the output from the mixing-section-outlet-side temperature sensor;
• and
• a tank disposed between the mixing section and the load, said tank having a capacity of about 10 liters or more, and being constructed such that the brine passes therethrough at a low speed in order to relieve a sudden temperature change of the brine from the mixing section.
