HEAT EXCHANGE SYSTEM

Japanese Patent JP2023149895

A

To provide a heat exchange system capable of suppressing freezing of a high temperature fluid when executing heat exchange between a low temperature fluid and a high temperature fluid of a fluid.SOLUTION: A heat exchange system 100 includes: a first heat exchanging part 3 for executing heat exchange between a low temperature fluid 80 and a high temperature fluid.81; and a second heat exchanging part 4 for executing heat exchange between the low temperature fluids 80. The second heat exchanging part 4 which includes a first inlet 4a into which the low temperature fluid 80 flows, a first outlet 4b communicated with the first inlet 4a, a second inlet 4c into which the low temperature fluid 80 flows, and a second outlet 4d communicated with the second inlet 4c is configured so as to execute heat exchange between the low temperature fluid 80 flowing from the first inlet 4a and the low temperature fluid 80 flowing from the second inlet 4c, and includes a heating part for heating the low temperature fluid 80 before flowing into the second inlet 4c. The second outlet 4d is communicated with the first heat exchanging part 3, and the low temperature fluid 80 subjected to heat exchange by the second heat exchanging part 4 and outflowing from the second outlet 4d is caused to flow into the first heat exchanging part 3 so that heat exchange is carried out with the high temperature fluid 81.SELECTED DRAWING: Figure 4
