Design and Analysis of the New Energy Supply System for the Ecological Solar Greenhouse

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.
