Experimental study, design and analysis of automatic air heater with various flow rates using for solar still system
Dr. Sujeet Kumar Mahobia and Dr. Manoj Kumar Solanki
Abstract
In this article, the automatic electric heaters are used for solar still for the purpose of preheated inlet water at certain temperature. There are several interaction parameters that affect system efficiency using various flow rates. These parameters are: speed of fan, heater coil, heater wall radiation, applied voltage, air flow rate, heater outlet air temperature, insulation thickness, and heater size. The temperature rises over time (10-60 minutes) when using fans at speeds of 200, 400, 600, 800 and 1000 rpm. When using a fan at 1200 rpm and maintaining the temperature at 62.3 °C for a period of time (40-60 minutes) at the same fan speed. It was also noticed that the temperature was high over time (10-60 minutes) at a fan speed of 1400 rpm.
