KOULIBALY, Amadou  e  GONZALEZ BAYON, Juan José. Modelling ofa solar collector for air heating. Energética [online]. 2015, vol.36, n.3, pp. 292-302. ISSN 1815-5901.

In this paper the modeling of a flat solar collector for air heating was developed. This collector works with natural convection. The analysis of the collector was made using unsteady mass and energy balances applied to each component of collector. The equations were solved usinga Visual Basic code with the target to simulate the dynamics performance of the collector when the operating conditions and the design parameters are modified. The dimensions of the collector, the material and dimensions of the covert, the material and dimensions of the absorber plate, the optic efficiency and the type and thin of the insulator are the fundamentals design parameters that can be varied. The results of the simulation show that the software can be used for the design of collectors for heating air.Additionally, the software permits to determine the temperature of each component, the instantaneous efficiency of the collector and offers the elements to obtain the time constant that characterize collector dynamics.
