- •
A novel multi-section absorption heat pump is developed for AHE in DH system.
- •
Performance of the entire multi-section AHE is tested in real project.
- •
The multi-section AHE was designed to realize large inlet/outlet temperature difference of external flow in each component.
- •
The new AHE has higher heat exchange effectiveness and better regulation performance.
- •
The simulation model for multi-section AHE is verified by the test data.
