Cooling system

A cooling system comprising:

• a cooling device that cools a heat medium;
• air conditioning means supplied with the heat medium to cool a room in which a load device is installed;
• a local cooling device supplied with the heat medium to cool the load device;
• and
• a heat medium loop that includes a first line through which the heat medium is circulated from the cooling device via the air conditioning means, and a second line that branches from the first line and through which the heat medium is circulated via the local cooling device,
• wherein the first line has a smaller pressure loss than the second line,
• wherein the first line is provided with an adjustment valve that, as an opening degree decreases, increases a ratio of a flow rate of the heat medium that is branched to and flows through the second line to a flow rate of the heat medium that flows without being branched to the second line.
