Building heating and cooling system - has heating and cooling circuits coupled to heat energy storage reservoirs defining elongate water flow path

摘要

The system includes a heating circuit and a cooling circuit. The circuits are coupled to heat energy storage reservoirs. Each reservoir defines an elongate flow path along which water can flow in the form of a column. Using heat from the heating circuit, the reservoirs can be charged with hot water which is stored in the reservoir(s). The stored hot water is subsequently used to boost the temperature in the heating circuit. Similarly, water cooled by the cooling circuit can be stored in other reservoir(s) for use in boosting the cooling action of the cooling circuit.
