Heat exchange system

A heat exchange system placed between a first chiller device for storing a first thermal medium, a second chiller device for storing a second thermal medium higher in temperature than the first thermal medium, and a control target object whose temperature is controlled by use of a temperature-regulating fluid, the heat exchange system comprising:

• a main circulation circuit configured to circulate the temperature-regulating fluid through the control target object and provided with a merging section and a diverging section provided between the merging section and the control target object;
• a first supply line for supplying the first thermal medium from the first chiller device to the merging section;
• a first return line for returning the temperature-regulating fluid from the diverging section to the first chiller device;
• a first bypass line for bypassing the first supply line and the first return line;
• a first latent heat storage member placed in the first return line at a position closer to the first chiller device relative to a low-temperature side connection point at which the the first return line and the first bypass line connect to each other, the first latent heat storage member being configured to store and release heat;
• a second supply line for supplying the second thermal medium from the second chiller device to the merging section;
• a second return line for returning the temperature-regulating fluid from the merging section to the second chiller device;
• a second bypass line for bypassing the second supplying line and the second return line;
• a second latent heat storage member placed in the second return line at a position closer to the second chiller device relative to a high-temperature side connection point at which the second return line and the second bypass line connect to each other, the second latent heat storage member being configured to store and release heat, the second latent heat storage member being higher in heat storage temperature than the first latent heat storage member;
• a flow distribution unit placed in the merging section and configured to distribute the temperature-regulating fluid, the first thermal medium, and the second thermal medium toward a control target object, the first bypass line, and the second bypass line;
• and
• a flow divergence control unit placed in the diverging section and configured to diverge the temperature-regulating fluid toward the main circulation circuit, the first return line, and the second return line.
