Construção e avaliação térmica de coletor solar plano para aquecimento de ar.

Abstract

This research determined the termic instantaneous performance of a solar collector of plane surface absorber for two distances between plate absorber and transparent material and for different air flows. The results showed that solar collector presented income termic between 42.6 the 77.4% for air flow between 9.3 to 17.5 m3.min-1. The air temperatures at collector outlet stayed between 5.8 the 10.2°C above the environment temperature.
