Abstract
System and method for storing and releasing energy comprising directing air into a vertical cold flue assembly. The assembly has an air inlet at or near the top and an air exit at or near the bottom. The air is cooled and a portion of moisture is removed from the air.
Claims5
A liquid air production system comprising:
- one or more inlet air compressors;
- a molecular sieve assembly fluidly connected to a first inlet air compressor;
- a vertical cold flue assembly fluidly connected to the molecular sieve assembly and to a second inlet air compressor, the vertical cold flue assembly having an air inlet at or near its top into which inlet air is directed and an exit at or near its bottom;
- one or more inlet air heat exchangers including a main heat exchanger fluidly connected to at least one of the plurality of inlet air compressors;
- a storage apparatus fluidly connected to the main heat exchanger;
- an absorption chiller using a working fluid, the absorption chiller being fluidly connected to the cold flue assembly;
- and
- a mechanical chiller containing refrigerant fluid, the mechanical chiller being fluidly connected to the absorption chiller;
- and
- a refrigerant loop air assembly fluidly connected to the mechanical chiller.
