Summary

Shell-tube falling film structure is commonly adopted for the main components in absorption heat pump (AHP). However, this structure leads to a large size. This work aimed to develop a detachable plate-type falling film heat transfer structure, to present a liquid-level-lifting type asymmetrical overflow distributor system to miniaturize the AHP system. In this work, a specific experimental system was developed. The experimental study under different solution temperatures and distributor dimensions were carried out to find the key factors which influence the wetting characteristics. A structure with optimal wetting performance was determined under the rated flow after the study. The overall wetting rate reached 95%, and the average thickness of liquid film was as low as 0.44mm.An optimized distributor with ideal wetting performance was presented, which promote the development of the detachable plate-type falling film AHP and the application of absorption technology.
