Abstract

Abstract: With the promotion of renewable energy, how to coordinate the efficient use of solar energy and indoor thermal comfort environment has become the key point for applying building integrated solar thermal system broadly. Thus, this paper presents a wall system integrated solar thermal collector. The influences of material and thickness of main layer on thermal performance of the wall system were calculated and analyzed. The results show that thermal performance parameters of the wall differ greatly in heating condition and non-heating condition. Compared with heating condition, heat transfer coefficient of the wall is smaller, and thermal inertia index and attenuation factor are larger in non-heating condition. The delay time of the wall in non-heating condition is 3.5h more than the time in heating condition.
