Does thermal battery technology improve exhaust heat recovery?
Traditional exhaust heat recovery systems are limited to real-time recovery of exhaust heat primarily for engine warm-up and fail to fully optimize exhaust heat utilization. This paper introduces a novel exhaust heat recovery system leveraging thermal battery technology, which utilizes phase change materials for both heat storage and reutilization.
What is energy storage?
Energy Storage provides a unique platform for innovative research results and findings in all areas of energy storage, including the various methods of energy storage and their incorporation into and integration with both conventional and renewable energy systems.
Is there a synergy between engine waste heat recovery and phase change thermal energy storage?
Currently, there is a paucity of research investigating the synergy between engine exhaust waste heat recovery and phase change thermal energy storage, particularly in the context of using recovered waste heat to preheat engine cooling water.
What is exhaust heat exchange module?
The exhaust heat exchange module encompasses exhaust pipes, three-way catalytic converters, exhaust heat exchange pipes, mass blocks for exhaust heat exchange tubes, water jackets for exhaust heat exchangers, and NOx post-processing units.
How do exhaust heat exchanger and thermal battery work?
The exhaust heat exchanger and thermal battery are connected in parallel within the engine cooling circuit, with control valves RV1 and RV2 managing the operation of their respective circuits. The inlet of the engine cooling water jacket connects to the water pump, while its outlet connects to the thermostat.
Why is exhaust heat recovery difficult at low exhaust temperature?
Thus, the sorbent in the sorption bed is required to be able to complete regeneration in a timely manner at a relatively low exhaust temperature, which increases the difficulty of the exhaust waste heat recovery. The exhaust temperature varies sharply with the engine load.
