摘　　要：利用太阳能发电驱动真空冰浆制备系统,减少系统对常规电力资源的消耗,可以达到节能减排的目的。本文对该系统建立经济分析模型,从单位供电成本、投资回收期角度进行经济性评价,为整个系统进一步优化提供依据。结果表明,系统单位运行成本仅0.19元/千瓦时,可获得较大的年净收益;系统在3.2年内可回收成本;太阳能电池投资占系统初投资的60%,是影响经济性的主要因素,可从此因素考虑进行系统优化。Using the vacuum preparation of ice slurry system driven by solar power to reduce the conventional power consumption, the purpose of energy conservation and emission reduction can be achieved. The economic analysis model for this system is established. The economic evaluation is conducted from the perspective of unit power cost and investment recovery period, which provides guidance for the optimization of the whole system. The results show that unit operating costs of this system is only 0. 19 yuan/（kW · h）,and it can get a larger annual net income. It takes 3. 2 years to recover the cost of the system. Solar battery investment accounts for 60% of the initial investment in the system, and it is the main factor affecting the economy, which can be taken into account for system optimization.
