As a renewable energy source, solar energy is c lean and resourceful. Exploting and utilizing solar energy has immense social an economic benefit.In this article, we first introduce the development of solar air collector, and make a comparison of mast kinds of solar air collectors. So I make some improvements in the ideas designed by my team members and develop a novel solar air collector with plane vacuum glazing and punching seams in absorber, which is high efficiency.Then we designed a novel type of collector and investigated this kind of collector model with or without vacuum glass by dynamic experiment, analysed the influencing factors of solar air collector, and obtained the performance parameter of the collector to verify the accuracy and reliability of the mathematical model. Then we set up the mathematical model of the new type high efficient solar air collector, and make a theoretical analysis on its heat exchange stituation and performance. On that basis, we take on a numerical simulation on the novel solar air collector. We investigate the collection efficiency of the collector under different height, air volume, as well as factors such as radiation intensity, and make a comparative analysis to the performance under the same size and different working condition.It is a conclusion through the research that the novel type of solar air collector is intergraded very well with building and have good act in heating and ventilating in winter and a transitional season, as well as drying affect on materia. It is a better use of the heat and have a value for in-depth study and application.
