Performance analysis of hybrid solar desalination system using ETC and CPC

Abstract

This paper present analytical and experimental analysis of hybrid solar desalination system using evacuated tube collector (ETC) and compound parabolic concentrator (CPC) to obtain the maximum amount of soft water for drinking and industrial purposes. In this paper, thermal performance of hybrid system with varying heights between ETC and CPC and flow rates are investigated with single effect boiling method. Water is used as working fluid for experimentation and tested for different climatic conditions of Pune city (located in western region in the Maharashtra state, India). The experimental set-up of thermosiphon solar water system mainly consists of ETC and CPC, condenser, inlet water tank, outlet collection jar etc. The CPC (reflector) is used to improve thermal performance of solar desalination system. Further, thermal performance of said solar desalination system has been improved with aluminium foil as CPC (reflector) material. From obtained results, it is concluded that for the climatic conditions of selected location, solar (ETC + CPC) hybrid desalination system could produce 1.5-2 l of fresh water per day and purity is validated as per ISO 12500-2012.

Mathematical Modelling and Analysis of Hybrid Solar Desalination System Using Evacuated Tube Collector (ETC) and Compound Parabolic Concentrator (CPC)

“…Moh'd et al [21] developed hybrid solar wind water desalination system, they argued that the yield can be three to four times more than conventional solar distillers. Their system mainly base on single basin solar still and a wind water heater whereas Kedar et al developed on performance analysis of hybrid solar desalination system using ETC and CPC [22][23][24], whereas Kabeel et al [25] were studies on review for water desalination using humidification and dehumidification techniques. This review would also be light on the scope further research and recommendations on active distillation system whereas Kalogirou [26] studies that seawater desalination using renewable energy sources.…”

Effect of Reflecting Material on CPC to Improve the Performance of Hybrid Groundwater Solar Desalination System

“…Bhambare et al [10] presented various desalination systems that are available in Oman. Kedar et al [11][12][13] mainly developed an evacuated tube collector and compound parabolic concentrator using a single-effect boiling method. The authors had done extensive experimental work for a hybrid solar desalination system.…”
