摘要
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 pro -posed.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 occur-rence 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 re-search direction of improving COP of the system was suggested .
