Experimental investigation on the solar air collector for northern China rural house

A simple structure, low cost solar air collector is very suitable for northern China rural house heating in winter. A solar air collector was developed and studied experimentally in winter. The research focused on the inclination angle of the collector influence its efficiency. The experiment result showed that when the inclining angle is 65°, it's efficiency increased 10%, compared with vertical solar air collector. The solar air collector developed has a good temperature distribution, low flow resistance. It is suitable for heating in rural house.
