Abstract

Special attention has been paid to build a simple solar air heater from cheap plastic wrapping film with air bubbles, for use in drying operations on a farm (grain, fruit, fish, etc.). The model used was a single-sheet cylindrical collector and, after it had gained some heat, another layer of the plastic wrapping film with air bubbles was added in a later stage to decrease convection heat losses to the surroundings. Each cylindrical collector was 5 m long and 0.36 m in diameter, with a black interior band covering the lower part of the collector (30% of the surface area). The inlet direction of the collector was always towards the wind in order to achieve maximum air flow inside the collector. Although the method used is simple, a considerable gain in the temperature of the airflow was obtained: a temperature difference of around 10°C was measured.
