PROBLEM TO BE SOLVED: To provide a bidirectional heat interchange system and a heat interchange transaction method in which high usage of a high performance heat source, renewable energy and unused energy is enabled between buildings of multiple buildings.SOLUTION: A bidirectional heat interchange system is constituted of thin piping enabling heat interchange of around 10% of a peak load of each supply and demand location, and a heat interchange piping connection device for performing heat transfer, heat metering and heat exchange. The heat interchange piping connection device is, as an example, configured such that a supply and demand location A holds a high performance heat source, and enables heat interchange only in a supply and demand location B when surplus heat is generated in the rated operation (supply and demand locations C, D do not perform heat interchange). The combination enables any combination by performing proper heat medium control between heat interchange connection devices. Further, a self-heat source is used for supplementation when it is insufficient only by receiving heat interchange. The heat interchange transaction method performs demand forecast of each supply and demand location, and the optimal operation plan of each heat source is created and proposed based on the estimation. Each supply and demand location makes a decision, registers heat interchange conditions, determines the heat interchange conditions in relative, and registers the conditions in the heat interchange connection devices as control command information.SELECTED DRAWING: Figure 3 |
