Title:

圧縮空気貯蔵発電装置及び圧縮空気貯蔵発電方法

Document Type and Number:

Japanese Patent JP6511378

Kind Code:

B2

Abstract:

A compressed air storage power generation apparatus 2 is provided with a motor 8a, a compressor 10, a pressure accumulation tank 12, an expander 14, a generator 16, a first heat exchanger 18a and a cold heat extracting unit 13. The motor 8a is driven by input power generated using renewable energy. The compressor 10 is mechanically connected to the motor 8a and compresses air. The pressure accumulation tank 12 accumulates the compressed air compressed by the compressor 10. The expander 14 is driven by the compressed air supplied from the pressure accumulation tank 12. The generator 16 is mechanically connected to the expander 14. The first heat exchanger 18a exchanges heat between the compressed air supplied from the compressor 10 and a heat medium and cools the compressed air to room temperature. The cold heat extracting unit 13 extracts air serving as working fluid as cold air of the room temperature or lower. Due to this configuration, the compressed air energy storage power generation apparatus 2 capable of smoothing input power that varies irregularly and efficiently performing heating and cooling with the input power is provided.
