为提高太阳能与辅助能源的综合利用率,提出了一种新型的太阳能喷射式与电压缩式有机结合为一体的联合制冷系统,进而对这种新型联合系统及传统联合系统进行了热力学对比分析,对联合系统太阳能喷射式制冷时最佳发生温度进行了选择,并计算了典型年气象条件下两种联合系统相对于电压缩制冷系统的节能量及节能率。结果表明:两种联合系统相对于电压缩式制冷系统而言都是节能的,但新型联合制冷系统比传统联合制冷系统更节能,更能高效地综合利用太阳能与常规能源。在文中计算条件下,新型联合系统比传统联合系统多节能13.6%。
In order to improve the comprehensive utilization ratio of solar energy and auxiliary energy, a new type of combined refrigeration system integrating solar jetting and voltage reduction is put forward. Then the thermodynamic comparative analysis of the new combined system and the traditional combined system is carried out. The optimal temperature for solar injection refrigeration system is selected. The energy saving rate and energy saving ratio of two kinds of combined systems are compared with those of the compression refrigeration system under the typical annual meteorological conditions. The results show that the two combined systems are energy-saving compared with the voltage-compression refrigeration system. However, the new combined refrigeration system is more energy-efficient than the traditional combined refrigeration system and can utilize solar energy and conventional energy more efficiently. Under the condition of calculation, the new combined system can save 13.6% more energy than the traditional combined system.
