Experimental investigation on novel evacuated tube collector with combined condenser heat pipe for solar desalination

Abstract

Planet Earth is covered with 70% of water. The geographical location of the Peninsulas has supreme solar energy and super-lasting sea saline water-rich reservoirs are given the goodness of God-gift. Solar desalination is an alternative adoption to get fresh water from brackish water as well as an evaluation of endless-energy-extremity, even with exclusive environmental conservation. In this study, a new Evacuated Tube Combined Condenser Heat Pipe Solar Desalination System (ETCCHP-SDS) was developed and analysed its performance. This system consists of an evacuated tube collector with a combined condenser heat pipe assembly, desalination unit, and a water tank. A different heat pipe layout was developed through joining entire the evaporator heat pipe section to a single combined condenser unit. Solar collector comprises a developed heat pipe system linked to the evacuated glass tubes. An innovatively introduced new combined condenser with heat pipe solar evacuated tube assembly heating system is efficient through its improved idea and design, provides uniform heating to intent the final heat transfer to the heat pipe, hot water temperature and first and second law of thermodynamics efficiency effectively and constantly increases under the various water flow rates without enhancing the cost calculations. Consequently, a combined condenser-based innovative heating system is evaluated as extra-efficient and else-new non-hostile to nature. Comparative computational, theoretical and trial testing analyses of a new combined condenser assembly were performed to evaluate the system performance. The experiments were performed in three phases during the study. Phase I was the comparative study which was performed for the water heating at various water flow rates through innovative combined condensers and traditional individual condensers. Phase II was performed by combining the new combined condenser heat pipe solar collector with a single slope solar desalination unit. Phase III study of a stand-alone solar desalination un
