Title:
COMPRESSED AIR ENERGY STORAGE AND POWER GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/163347
Kind Code:
A1
Abstract:
A CAES power generation device 1 comprises: a compression/expansion machine 10; an accumulation unit 5 that stores compressed air; a low-temperature water storage tank 7b and a high-temperature water storage tank 7a; heat exchangers 41–43; and fluid maintenance units 46, 60, 62. The compression/expansion machine 10 has a function that uses power and compresses air and a function that generates electricity by expanding the compressed air. The low-temperature water storage tank 7b and the high-temperature water storage tank 7a store water in a liquid state and are fluidly connected to each other. Heat exchange between the compressed air and water occurs in the heat exchangers 41–43. The fluid maintenance units 46, 60, 62 pressurize water that flows through the heat exchanges 41–43 and maintains the water in a liquid state.
