AI Technical Summary
Existing absorption thermal energy storage cycles suffer from problems such as unstable vacuum operation of the system, pipe crystallization blockage, corrosion, and poor thermal storage effect. Furthermore, traditional single-stage cycles cannot effectively solve the environmental dependence of renewable energy and the intermittent nature of energy supply.
The two-stage absorption-compression composite energy storage system using ionic liquid absorbent includes a winter energy release cycle and a summer energy storage cycle. Through multiple shut-off valves and valve port switching, combined with compressor auxiliary cycle, it realizes cross-seasonal energy storage and release, improves refrigerant evaporation rate and concentration difference, and enhances absorption capacity.
It achieves efficient energy storage and release across seasons, improves energy utilization, reduces environmental pollution, enhances thermal storage capacity and temperature application range, and reduces energy waste.
