System and Distribution Tank for Low-Energy Network

Abstract

A system for a low-energy network includes a collector circuit ( 1 a , 1 b ) filled with a first transfer solution, a heat transfer circuit ( 7 ) filled with a second transfer solution, and a terminal ( 3 ) adapted to transfer heat between the transfer solutions of the collector circuit ( 1 a , 1 b ) and the heat transfer circuit ( 7 ). The collector circuits ( 1 a , 1 b ) are connected to the terminal via two distribution reservoirs ( 82, 81 ), of which the first distribution reservoir ( 81 ) is isolated and configured to receive and transfer heated transfer liquid, and the second distribution reservoir ( 82 ) is configured to receive and transfer cooled transfer liquid, and at least one collector circuit ( 1 a , 1 b ) connecting the first distribution reservoir ( 81 ) and the second distribution reservoir ( 82 ) is connected to each distribution reservoir ( 81, 82 ) terminating the low-energy network. The system may also include a distribution tank ( 80 ) for the low-energy network.
