英文摘要	The flat plate solar air collector with double channels was proposed based on flat plate solar collector used widely in hot water supply, building heating, air conditioning and other fields. The air flow channels of air collector were arranged in length direction of the collector, the entrance and exit positions were arranged in diagonal form. The test platform of air collector was established to test and analyze the thermal performance of improved air collectors. The results show that the average and maximum efficiency of air collector based on the day lighting area are 51.29% and 53.93%, respectively when the average solar radiation intensity and environmental temperature are 535.2 W/m2 and 22.2, the mass flow rate of air is 0.024 kg/s, respectively. The maximum temperature rise and temperature difference of the working fluid(air)are 60.4 and 40.6, respectively, and the heat transfer factor is about 0.55. The length of air flow channel can be increased and the convection heat transfer between working fluid and absorber plat can be strengthened for diagonally arranged air inlet and outlet flow of double flow channels. This type of solar air collector has the advantages of convenient remodeling, low cost, easy industrialization, and can be applied to the field of heating, drying and ventilation, etc. © 2016, Editorial Board of Acta Energiae Solaris Sinica.
