In this report, we will understand how “solar air conditioning” is being implemented in commercial and residential applications.
Does solar air conditioning really meet the requirements for today’s “Green Energy” demand; and is it ready to be implemented? Solar air conditioning is any air conditioning system that uses solar power. This can be achieved through passive solar, solar thermal energy conversion and photovoltaic conversion (sunlight to electricity) methods. >Passive solar does not use thermal energy to create a cold environment or drive any direct cooling processes. Is implemented by using Cool roofs, that are roofs that can deliver high solar reflectance (the ability to reflect the visible, infrared and ultraviolet wavelengths of the sun, reducing heat transfer to the building) and high thermal emittance (the ability to radiate absorbed, or non-reflected solar energy), and green roofs or living roofs, which are roofs of buildings that are partially or completely covered with vegetation and a growing medium, planted over a waterproofing membrane. It may also include additional layers such as a root barrier and drainage and irrigation systems. (Specifying the word "green" refers to environmentalism and not the color green, as with green roof tiles or roof shingles), using the mechanisms of heat transfer: heat conduction, convective heat transfer, and thermal radiation. >Solar thermal energy conversion is implemented mostly in commercial and industrial applications and is encountered in two different types such are: a- Solar open-loop A/C; using air passing over solid desiccants (like silica gel or...
