A calculation method of radiant time factors is presented and the method is used to calculate radiant cooling load. Based on experimental data of total heat gain and total cooling loads collected within 24-h, radiant heat gain and radiant cooling load can be calculated through convection and...

In view of system efficiency and environmental protection, it is of primary importance to harvest solar energy better and better for example by means of developing solar collectors. Mathematical modelling is the theoretically established tool for it, for example with using the collector transfer...
