The key to creating a material that would be ideal for converting solar energy to heat is tuning the material’s spectrum of absorption just right: It should absorb virtually all wavelengths of light that reach Earth’s surface from the sun — but not much of the rest of the spectrum.
Cold wind inlet Fig. 1 The structure of solar air conditioning / heating system The working principle of the system is that under normal working conditions of the solar cell, the heat of battery panel is taken away by the flow of the working fluid, which is water and water vapor, in the gravity heat pipe that is made of copper materials [4, 5] .
Conduction is the heat transfer process through a material due to direct contact between particles. When one part of a material gets hot, its molecules gain kinetic energy and vibrate, passing it to neighboring molecules. This process continues until the heat spreads throughout the material. 3.2. Fourier’s Law of Heat Conduction
Solar radiation is the radiant energy emitted by the Sun (by way of nuclear fusion) that creates an electromagnetic wave with wavelength between \ ( 0. 30\mu m - 3\mu m \) as well as photons in visible wave length. In this chapter, the basic concepts of solar radiation and heat transfer are discussed.
In solids, it is due to the energy transfer by free electrons and the combination of vibrations of the molecules in a lattice. Geometry of the medium plays an essential role for the heat-conduction rate, i.e., the temperature difference across the medium as well as thickness and material of the medium.
Heat transfer media (HTM) refers to the fluid or other material that is used to transport heat from the solar receiver to TES and from TES to the turbine or industrial process. Existing state-of-the-art CSP plants use a liquid, molten nitrate salts, as both the TES and HTM materials.
