SYSTEM FOR STORING AND OUTPUTTING THERMAL ENERGY HAVING A HEAT ACCUMULATOR AND A COLD ACCUMULATOR AND METHOD FOR THE OPERATION THEREOF

摘要

The system has a heat storage (14) and a cold storage (16), where the heat storage releases the stored heat to a line (40) in a discharge circuit for a working medium. The units are connected with each other by the line in the discharge circuit. The cold storage delivers the stored cold to another line (52) that forms a closed circuit. A thermal fluid energy-machine (43), particularly a pump (58) is inserted as working machine and is provided behind the delivery point for the cold stored in the cold storage. An independent claim is included for a method for storage and delivery of thermal energy over a heat storage and a cold storage.
