摘　　要：建立了槽式抛物面太阳能聚焦集热器(PTC)的一维、非稳态传热模型,给出了沿轴线的光强分布公式,对PTC的热性能进行了数值模拟,并与实验结果进行了比较,模拟结果与实验结果的误差在4.61%以内,两者吻合较好,验证了模型的合理性。对采用不同形式集热器的太阳能双效吸收式制冷系统的性能进行了分析对比,结果显示,采用PTC的太阳能吸收式制冷系统具有最佳的系统性能。An unsteady, one-dimensional heat transfer model of P-FC was presented in this article. The distribution of the concentrated solar radiation along focal axis has be calculated. The thermal performance of the PTC was simulated, and the simulated results were compared with the experimental results. The comparison showed that the simulated and experimental results are in good agreement, and the difference between them is within 4.61%, which means the model set up is reasonable. The comparison of performance of double-effect solar absorption cooling system with different type of solar collector is made, and the result showed that the solar absorption cooling system with PTC has the best system perfor- mance.
