Two devices that intercept solar radiation for heating purposes are solar water heaters and solar air heaters.
1. Solar water heaters: These systems use solar thermal collectors to absorb and convert sunlight into heat energy. The collected heat is then transferred to water or a heat transfer fluid, which is used for hot water heating in residential or commercial buildings. There are two types of solar water heaters: passive and active. Passive systems circulate water through natural convection, while active systems use pumps to circulate the fluid.
2. Solar air heaters: These devices are designed to directly heat the air using solar energy. They typically consist of an absorber plate or collector that absorbs solar radiation, a glass cover to trap the heat, and an air duct system to distribute the heated air. Solar air heaters are commonly used for space heating in residential, commercial, or industrial applications. They can be mounted on a roof or wall, and are especially effective in cold climates.
