Abstract

In this paper, the effect of the different parameters such as solar radiation, and ambient temperature on thermodynamic performance of a Water-in-glass evacuated tube heat pipe (ETHP) is studied, including energy, exergy, environmental, economic analysis, and sustainability index. The ETHP system is evaluated under the 4E criteria; energy, exergy, economic, and environment. The energy, exergy, environmental, enviroeconomic, exergoenvironmental, exergoenviroeconomical analysis and sustainability index of the ETHP system is calculated. There are 4 collectors each collector 57 pipes as a total of 108 pieces pipes, a hot water tank, a heat exchanger, and a pump in the system. The water is used as a working fluid due to economic, and common use in the system. In the result of this experimental study, we calculated energy and exergy efficiencies of the EHTP system as %60.74 and %40.72, respectively. In addition, the environmental, exergoenviromental, enviroeconomic, and exergoenviroeconomic values of the EHTP system are found 5958.01 kgCO2/day, 5564.72 kgCO2/day, 0.7448 $/day and 0.6958 $/day, respectively. Also, the sustainability index of the system is found as 1.687.
