| 英文摘要: |
| As a refrigerating unit utilizing waste heat or other low-grade sources of energy, the lithium-bromide absorption chiller is considered to be an alternative for air-conditioning applications. In the chiller system consisting of the absorber, the generator, the condenser, the evaporator and the solution heat exchanger, a series of heat and mass transfer processes occur, with which the thermodynamic cycle for refrigeration is formed. In this presentation, problems existing in the thermodynamic cycle, performance of heat and mass transfer equipment, and in the construction of the domestic lithium-bromide absorption chillers were discussed from a thermal-engineering viewpoint. It was proposed that chiller systems with rationally matched devices and new types of construction and flow process ought to be developed. Research on the absorption mechanisms, development and application of surfactants and high-performance enhanced heat and mass transfer elements ought to be carried out. |
