Este artigo apresenta uma revisão sobre asprincipaistecnologias de dessalinização térmica associadas a energia solar. O concentrador solar parabólico é uma tecnologia de aproveitamento de energia solar que consiste basicamente em aquecer um fluido de trabalho (água, óleos minerais ou sintéticos, ar) que está presente em umsistema, sendo então capaz de fornecer energia térmica. Quantos aos dessalinizadores térmi...
Solar thermal desalination systems operate with a variable heat source, such as solar radiation, which makes it difficult to identify the influence of process variables and constructive geometric parameters in their performance. In operation, brackish or salt water is heated in a storage tank, where it evaporates and condenses on the lower walls of a metal tray (first stage) installed above this tank. The steam...
A parabolic solar concentrator is a type of reflector utilized to increase the radiation intensity on a surface. In order to have a proper reflection of solar radiation, the parabolic reflector should constantly track the sun’s position so that solar rays are converged to a tube that is at the focus position of the parabola. The purpose of this study is to develop an electronic control system for low-cost parab...
