摘要


Falling film absorber is widely used in ammonia water absorption refrigeration unit. It has the advantages of large gas-liquid contact area, high heat transfer efficiency and simple structure. The research progress of horizontal tube, vertical tube and plate falling film absorber at home and abroad is reviewed. The present research shows that the research of falling film absorber is getting mature and has broad application prospects.
