本文针对由线聚焦菲涅尔太阳能集热器驱动的集热、蓄热、空调系统中的单/双效吸收式制冷机,采用数学建模的方法,对制冷机的运行性能进行了分析。当热水温度位于85o C以上时,制冷机运行单效模式,额定制冷量为91k W,COP为0.6-0.7;当温度达到145o C以上,运行双效模式,额定制冷量为134k W,COP为1.1-1.2。计算对制冷机的各项运行参数进行了计算分析,并通过实验对制冷机的性能模拟结果进行了对比,验证了模拟的准确性。
In this paper, a single / double effect absorption chiller driven by a Focused solar collector is introduced. The mathematical model is used to analyze the operation performance of the chiller. When the hot water temperature is above 85o C, the refrigerator operates in a single-effect mode with a rated capacity of 91k W and a COP of 0.6-0.7. When the temperature reaches 145o C or higher, the dual-mode operation is run with a rated cooling capacity of 134k W and a COP For 1.1-1.2. Computation and calculation of various operating parameters of the refrigerator were carried out, and the performance simulation results of the refrigerator were compared through experiments to verify the accuracy of the simulation.
