Abstract

This work presents the design, objectives and first measurements performed on a passive solar collector for water heating installed in harsh environment conditions. These conditions include short and cloudy winter days, very low temperatures and strong winds. The information is considered of importance due to the scarcity of such measurements in Southern Hemisphere regions. This research is being performed in Río Gallegos (51° 30´ lat. S), on the Argentine side of Southern Patagonia. A Watersun evacuated tube solar collector is already producing hot water at the Energías Alternativas Test Site of the University, and a flat plate passive solar collector is to be installed at another research facility located near Cabo Vírgenes during 2001. A ReSol GmbH (Germany) calorimeter and a data acquisition system with two temperature, one volume displacement, and one separate radiation sensor is used to assess the system performance. Data can be accessed through a ReSol VBUS interface to a remote PC or directly on an LCD display. A comparison of performance of both technologies will thus be possible in similar climatic conditions, and conclusions about drawbacks and special requirements will provide a better picture to potential local consumers.
