Heat exchange system with a cooling device and method for exchanging heat by using the heat exchange system

A heat exchange system, comprising:

• at least one horizontal heat exchange chamber with heat exchange chamber boundaries which surround at least one heat exchange chamber interior of the at least one horizontal heat exchange chamber, wherein:
• the heat exchange chamber boundaries comprise at least one first opening for guiding in an inflow of at least one heat transfer fluid into the at least one heat exchange chamber interior and at least one second opening for guiding out an outflow of the at least one heat transfer fluid out of the at least one heat exchange chamber interior;
• at least one heat storage material is arranged in the at least one heat exchange chamber interior such that a heat exchange flow of the at least one heat transfer fluid through the at least one heat exchange chamber interior causes a heat exchange between the at least one heat storage material and the at least one heat transfer fluid;
• the at least one horizontal heat exchange chamber is located at a soil area of a soil;
• and
• at least one cooling device is arranged between the at least one horizontal heat exchange chamber and the soil for inhibiting a heat transfer from the at least one horizontal heat exchange chamber to the soil;
• wherein the heat exchange system is equipped with at least one discharging unit for discharging the at least one heat transfer fluid of the outflow from heat for production of electricity.
