Abstract
As the global warming due to greenhouse effect has become serious problem, it is necessary to introduce the technology, for instance, such as diversity or saving of energy to reduce the use of fossil fuel. The purpose of this study was to investigate the characteristics on materials of absorption plate, unpowered and minimum use of power in cooling and heating combined device. As the results, it was observed that, in case of summer, since temperature of absorption device of solar heat(ADSH) was lower than that of no ADSH, cooling effect was insignificant in case of being not installed cold-reservoir. However, in case of winter, heating effect was certified even though the power was not used. At secondhand, the performance of ADSH with Cu was higher 2 times than that of ADSH with Al.
