Saulės kolektoriaus su metaliniu absorberiu pasyvioje patalpų šildymo saulės energija sistemoje

Abstract

Summary Studied passive solar heating system - this is a brick wall of the building. Tests of silicate white brick wall with a thickness of 0.52 m, an area of 11 m2 was painted in matt black paint, and the isolated 5.0 mm thick pressed wood and 15 mm foam layer. The upper and the lower parts of the walls harvested the same, 0,037 m2 cross-sectional area, air vents move. On the wooden rails, lea¬ving a gap of 20 mm mounted 0.55 mm thick black-painted tin. Between the inner surface of the transparent cover plate and 90 mm apart. In order to increase the efficiency of the collector, equipped with rails. In such an air flow path increases the flat absorber surface drag. The average daily rate of efficiency, changing the relative amount of traction air from 11m3/ (h-m2) to 24.5 m3 / (h-m2) respectively, varied from 0.71 to 0.76.
