Abstract
In this paper, a heat pipe evacuated tube solar collector has been
investigated both theoretically and experimentally. A detailed theoretical
method for energy and exergy analysis of the collector is provided. The
method is also evaluated by experiments. The results showed a good agreement
between the experiment and theory. Using the theoretical model, the effect
of different parameters on the collector?s energy and exergy efficiency has
been investigated. It is concluded that inlet water temperature, inlet water
mass flow rate, the transmittance of tubes and absorptance of the absorber
surface have a direct effect on the energy and exergy efficiency of the heat
pipe evacuated tube solar collector. Increasing water inlet temperature in
heat pipe evacuated solar collectors leads to a decrease in heat transfer
rate between the heat pipe?s condenser and water.
