An Experimental Investigation on a Double-Pass Solar Air Heater Using Two Separate Extended Geometry in the Absorber Plate Filled with TESM

Abstract

A dual-pas solar air heater with two separate shapes and in five different configurations carrying thermal energy storage systems has been manufactured and investigated. Paraffin wax as a tool for solar TESM is used during the investigation of PCM loaded configurations. The heater's efficiency has been examined for five distinct configurations. The integrated solar heater using TESM provided a reasonably higher temperature than without energy storage. As a result, air heaters that are equipped with thermal energy storage performed better than those that are not. The addition of a solar energy storage material with a collector plate is found to be the best arrangement since it enhances the solar air heater's operating period. During investigation, configuration 4 has been found to be more effective than other configurations.
