Experimental investigation of solar desalination system using evacuated tube collector

Abstract

An experimental investigation is carried out for softening of hard water by using solar desalination system with an evacuated tube collector. The experimental study mainly involves various parameters such as the temperature of hard and soft water, an ambient temperature of water, water flow rate, intensity of solar radiation and wind velocity. The primary purpose for an experimental study to get a maximum amount of soft water using evacuated tube collector. It is observed that in evacuated tube solar collector system gives the higher outlet temperature of water and has the better results for the thermal performance of the energy system. The entire test is done for environmental and climatic conditions of Pune city which is located in the western region in India. The experimental analysis show that evacuated tube solar collector system gives 27-28 liters of soft water per day.
