太阳能蔬菜生产配送基地组合系统

设计了可为蔬菜种植、挑选清洗、预冷、冷藏(速冻和冻藏)各个环节的空间场所提供太阳能辅助热源,并以水和CO2为工质的蔬菜生产配送基地组合系统,通过对中国4个典型地区的计算分析,并与完全用电驱动的组合系统比较得出,不同地区由于环境温度和太阳辐照能不同,太阳能组合系统的性能具有明显的差别,广州地区环境温度高,太阳能组合系统全年节约电能和运行费用达69.6%,兰州地区太阳辐射强度大,全年节约60%的电能和运行费用,乌鲁木齐地区全年节约电能和运行费用为49.2%,北京地区尽管环境温度和太阳辐射强度较低,全年也可节约7.8%的电能和运行费用。

Combined System of Solar Energy Vegetable Growth and Distribution Center

A combined system driven by solar energy and used in vegetable growth and distribution center was designed. This combined system used solar energy as the assistant heat source, water and CO2 as the working fluid. It can provide fit temperature environmental space needed by many different locations such as vegetable growth, pick, wash, pre-cooling, cooling storage (or quick freeze and frozen storage). By calculation and analysis to the combined system driven by solar energy and used in four representative areas selected in China, and the comparison between the combined system driven by solar energy with that driven by full-electricity, the results were obtained. They show that the performances of the combined system driven by solar energy in different areas have obvious differences. In Guangzhou area, the combined system driven by solar energy saved about 69.6% of electricity and the running cost in a year due to the higher environmental temperature. In Lanzhou area, the combined system driven by solar energy economized about 60% of the electricity and running cost in a year owing to the higher solar radiation intension, and in Urumchi area, the combined system driven by solar energy can also reduce about 49.2% of electricity and running cost in a year. However, even though the lower environmental temperature and solar radiation intension in Beijing area, still the electricity and running cost consumption of the combined system driven by solar energy reduced by 7.8% all year round too.
