【摘要】 新能源补给系统是生态日光温室的重要组成部分,用以保证寒冷地区冬季日光温室正常生产和农户日常生活用能,同时减少常规能源的使用。现阐述了该系统的组成、运行方式和参数的设计过程,分析了6种不同太阳能贡献率的新能源补给系统的经济效益和环境效益。结果表明:当新能源补给系统全部由太阳能提供能源时,CO2年排放量为0,与使用采暖炉做比较,每年可减少CO2排放15 684.79kg,与使用电能做比较,每年可减少CO2排放51 773.16kg。与使用常规能源相比,该系统具有运行费用低,节能减排的特点。更多还原

【Abstract】 New energy supply system was used for the ecological solar greenhouse in the cold winter of Chinese cold region.The system could provide the energy to the greenhouse for the regularly agriculture production and peasant living.The component,operation mode and the parameters of the new energy supply system were elaborated.On the basis of design,six classes as the ratio of solar energy were analyzed through the environmental benefit and economic benefits compared with its using the conventional energy sources before.The results showed that when new energy supply system all provided by solar energy,CO2 emissions was zero,and compared with use vesto,could reduce CO2 emissions 15 684.79 kg per year,and compared with use power,CO2 emissions could reduce 51 773.16 kg per year.In conclusion,compared with normal heating system,it was an energy saving,environmental protection and economical system.更多还原
