<p>A System (10) for using surplus heat energy, in particular from a district cooling (12), comprises a cycle (14) for circulation of a working fluid, the cycle (14) includes a vaporizing unit (16) for taking up the surplus heat energy and vaporizing the working fluid to become gaseous, a compressor unit (18) for compressing the gaseous working fluid, a condenser unit (20) for condensing the compressed gaseous working fluid to become liquid and releasing heat energy to a heat carrier (24), and an expansion unit (22) for reducing the pressure of the liquid working fluid. The system (10) further includes a second vaporizing unit (26) being connected to the cycle (14) via the condenser unit (20) for taking up heat energy from the heat carrier (24) and vaporizing a second working fluid to become gaseous, and a second expansion unit (30) for expanding the gaseous second working fluid.</p> |
