Title: COMPRESSED AIR STORAGE POWER GENERATING DEVICE AND COMPRESSED AIR STORAGE POWER GENERATION METHOD
Abstract:
A compressed air storage power generation device 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 takeout part 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 compressed air compressed by the compressor 10. The expander 14 is driven by 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 compressed air supplied from the compressor 10 and a heat medium and cools the compressed air to the vicinity of room temperature. The cold takeout part 13 takes out air that is a working fluid as cold air of no more than room temperature. Due to this configuration, the compressed air storage power generating device 2 capable of smoothing input power that varies irregularly and efficiently performing heating and cooling with the input power is provided.
