| description | The horizontal tube spray falling film evaporator is an efficient evaporation equipment, which has the advantages of good heat exchange effect, small equipment volume and low cost. In this paper, R245fa is used as the working fluid to build a heat transfer test platform for the horizontal pipe spray falling film evaporator of the Organic Rankine Cycle(ORC) power generation system. The effect of factors such as the spray density of the organic working fluid, the initial temperature of the geothermal water and the flow on the heat transfer coefficient outside the tube is studied. The experimental results show that with the increase of the spray density of the organic working fluid, the initial temperature of the geothermal water, and the flow of the geothermal water, the heat transfer coefficient first increases and then decreases. |
