|
摘要
对拉林线车辆整备库的槽式太阳能集热器与CO_2热泵复合采暖系统,利用TRNSYS软件建立仿真平台,分析集热器面积、集热器聚光比、单位集热面积水箱容积与热泵设计容量等设计参数对复合采暖系统性能的影响,采用正交试验法,以综合评价指标CEI为目标优化设计参数,优化结果对高寒地区同类供暖工程参数的确定有参考意义。
In this paper, relied on a preparation workshop for railway station building in Larin, the simulation model of the parabolic trough collectors and CO_2 heat pump combined heating system was based on the platform of TRNSYS. Found out the influence of solar collector area,concentration ration,storage tank volume of per unit collector area and the capacity of heat pump on the system performance. Used orthogonal experimental design method and taked comprehensive evaluation index(CEI) as objective functions to optimize system parameters. The results had reference value for analyzing and determining design parameters of similar engineering in alpine region.
