| Abstract: | Energy efficient greenhouse equipped with bubble thermal insulation system is an innovative technology attempting to reduce indoor energy consumption.Transparent liquid foam filled in a cavity envelope of greenhouse presents excellent insulation performance by decreasing energy loss or accumulation through heat transfer between the inside microclimate and outside environment.By using computational fluid dynamics code（CFD）,the factors influenced insulation performance of energy efficient greenhouse as well as the structural designs for ventilation openings have been researched and optimized systematically.In addition,CFD has been used to predict the insulation capability of energy efficient greenhouse in cold days and ventilation efficiency in hot weather,which provided the basis for the design of energy efficient greenhouse. |
