Title:
内部熱交換器を有する熱電気エネルギー貯蔵システム及び熱電気エネルギーを蓄えるための方法
Document Type and Number:
Japanese Patent JP2013507559
Kind Code:
A
Abstract:
A thermoelectric energy storage system (TEES) and method for converting electrical energy into thermal energy to be stored and converted back to electrical energy with an improved round-trip efficiency are disclosed. The TEES comprises a working fluid circuit for circulating a working fluid through a first heat exchanger (18) and a second heat exchanger (20), a thermal storage medium circuit for circulating a thermal storage medium, the thermal storage medium circuit having at least one hot storage tank (24) coupled to a cold storage tank (22) via the first heat exchanger (18). The arrangement maximises the work performed by the cycle during charging and discharging for a given maximum pressure and maximum temperature of the working fluid. Advantageously, this maximises the round-trip efficiency of the system.
