STORAGE OF EXCESS HEAT IN COLD SIDE OF HEAT ENGINE

Title:

STORAGE OF EXCESS HEAT IN COLD SIDE OF HEAT ENGINE

Document Type and Number:

WIPO Patent Application WO/2018/125510

Kind Code:

A3

Abstract:

Extra heat in a closed cycle power generation system, such as a reversible closed Brayton cycle system, may be dissipated between discharge and charge cycles. An extra cooling heat exchanger may be added on the discharge cycle and disposed between a cold side heat exchanger and a compressor inlet. Additionally or altematively, a cold thermal storage medium passing through the cold side heat exchanger may be allowed to heat up to a higher temperature during the discharge cycle than is needed on input to the charge cycle and the excess heat then dissipated to the atmosphere.
