Abstract
The paper deals with the experimental investigation of thermal analysis for a simple greenhouse type solar timber kiln. Four mixed charges of four hardwood species were dried in the kiln throughout the year. The energy inputs and outputs were calculated. The results showed that the combined overall efficiency of the kiln was 18% which indicated a reasonable performance for this type of solar kiln. Areas of heat use and loss were identified and suggestions were made for improving the heat efficiency of this type of drier.
Zusammenfassung
Diese Arbeit beschreibt die thermische Analyse eines einfachen Solartrockners vom Glashaustyp. Vier gemischte Chargen aus vier Laubholzarten wurden während eines Jahres getrocknet. Die Energielilanz des Trockners wurde berechnet. Die Ergebnisse zeigten eine mittlere Gesamteffektövität von 18% und damit eine annehmbare Leistung dieses einfachen Solartrockners. Bereich des Energieverbrauchs und -verlusts wurden bestimmt und Vorschläge erarbeitet, um die Effektivität dieses Trocknertyps zu verbessern.
