Title:
COMPRESSED AIR STORAGE POWER GENERATOR
Document Type and Number:
Japanese Patent JP2018178887
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent freezing of an exhaust port of an expander, in a compressed air storage power generator.SOLUTION: A compressed air storage power generator 1 includes a motor 10, a compressor 11, a pressure accumulation tank 12, an expander 13, a generator 14, an expansion-side heat exchanger 16, an air temperature sensor 5b detecting a temperature of the air flowing into the expansion-side heat exchanger 16, a pressure sensor 5a for detecting an air pressure, an air flow sensor 5c, a heat medium temperature sensor 5d for detecting a heat medium temperature, a heat medium flow sensor 5e for detecting a heat medium flow rate, a state changing portion for changing at least one of these five state amounts, and a control device 40 having a calculation portion 41 for calculating an exhaust temperature of the expander 13 on the basis of, at least, detection values of these five state amounts, and a state control portion 42 for controlling the state changing portion to increase the exhaust temperature when the exhaust temperature calculated by the calculation portion 41 is a prescribed temperature or less.SELECTED DRAWING: Figure 1
