摘要(Abstract):

提出了与太阳能热利用结合的单压吸收式制冷循环系统,对该系统部件进行了热力性能设计计算并分析了系统的可行性。针对不同的蒸发温度、冷凝温度和发生温度对系统COP的影响进行分析,得出相应影响曲线。分析结果表明:系统理论可行,但总COP较低;提高蒸发温度、冷凝温度和发生温度均有利于提高系统的COP,但提高具有局限性,并展望提高系统COP的研究方向。
The single-pressure absorption refrigeration cycle system combined with the heat utilization of solar energy was proposed. Detailed thermal performance calculation on single-pressure absorption refrigeration cycle system was provided,And the feasibility of the system was analyzed. The impact of different evaporation temperature,condensation temperature and the occurrence temperature on the system COP was analyzed and calculated,Then the influence curve was revealed. The results showed that the system was theoretically possible but COP was lower. The increase of evaporation temperature,condensation temperature and generation temperature were conducive to improving the system COP,however the increased value had limitations. The research direction of improving COP of the system was suggested.
