THERMAL ENERGY STORAGE AND RECOVERY SYSTEM COMPRISING A STORAGE ARRANGEMENT AND A CHARGING/DISCHARGING ARRANGEMENT BEING CONNECTED VIA A HEAT EXCHANGER
First Claim
1. A thermal energy storage and recovery system comprisinga storage arrangement having a thermal energy storage device for temporarily storing thermal energy;
- a charging/discharging arrangement having a fluid energy machine for exchanging mechanical work with a working fluid cycling through the charging/discharging arrangement; and
a heat exchanger arranged between the storage arrangement and the charging/discharging arrangement and thermodynamically couples a heat transfer fluid cycling through the storage arrangement with the working fluid,wherein the storage arrangement is configured in such a manner that the heat transfer fluid is under a first pressure,wherein the charging/discharging arrangement is configured in such a manner that the working fluid is under a second pressure, andwherein the second pressure is higher than the first pressure.

Abstract
A thermal energy storage and recovery system including a storage arrangement having a thermal energy storage device for temporarily storing thermal energy, a charging/discharging arrangement having a fluid energy machine for exchanging mechanical work with a working fluid cycling through the charging/discharging arrangement, and a heat exchanger which is arranged between the storage arrangement and the charging/discharging arrangement and which thermodynamically couples a heat transfer fluid cycling through the storage arrangement with the working fluid is provided. The storage arrangement is configured in such a manner that the heat transfer fluid is under a first pressure and the charging/discharging arrangement is configured in such a manner that the working fluid is at least partially under a second pressure, wherein the second pressure is higher than the first pressure.
