中文摘要:建立了带抛物槽式集热器的太阳能再热式有机朗肯循环发电系统模型,研究了再热式有机朗肯循环系统热效率增加量与输出功增加量随蒸发温度的变化规律。结果表明:当再热压力比为0.25时,太阳能再热式有机朗肯循环系统能有效地提高系统总效率,输出功随蒸发温度增加近似呈线性增加。对分别以R11、R114、R134a和R245fa 为工质的再热式有机朗肯循环系统热效率提高量进行比较,以R245fa为工质的再热式有机朗肯循环热效率提高最大,达4.3%。

Abstract:Solar low-temperature waste heat sources below 200℃ were analyzed from the perspective of thermodynamics and an organic Rankine cycle (ORC) power generation system of solar reheat using trough collectors based on the basic solar power ORC generation system was designed. The thermal efficiency of working fluids and the influence of various parameters on the system were studied by establishing a thermodynamic calculation model with four chosen organic substances. The thermal efficiency and net output power of the reheat ORC system and the basic Rankine cycle at different evaporation temperatures, as well as the influence of operating environment on the system were studied by modeling analysis of parabolic trough collector and ORC system. When the reheating pressure ratio was 0.25, results showed that the reheating ORC system can efficiently improve the total efficiency of the system, and the output power increased linearly as evaporation temperature increased. The effect of different working fluids on the ORC system was compared, and the efficiency increase was the largest when using R245fa, which was increased by 4.3%. As the evaporation temperature increased, the overall system efficiency with R245fa as working fluid firstly increased quickly but then increased slowly, and reached the largest value at evaporation temperature between 110℃ and 130℃. Wind speed had minimal influence on the system efficiency, causing changes of only around 1%, while light intensity had great influence on the system efficiency. As light intensity increased, the total efficiency of the system was increased by 5%.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
