Performance Analysis of Solar Evacuated Tube Collector

Article Preview

Abstract:

The high temperature operation of Evacuated Tube Collectors (ETC) and their very low radiant heat losses make them ideal for solar water heating, solar space heating, desiccant air conditioning, thermal driven cooling and industrial process heating applications. The work temperature of common ETC can reach 100~ 250°C. The vacuum tube envelope minimizes heat loss and ensures high collector durability and steady performance. This paper investigates different types of solar thermal collectors and compared them so that the result which the heat loss of ETC is least is obtained. The thermal analysis and performance of ETC are investigated as well.
