In the Andean region of Southern Peru, poverty and climate are extreme: at 4000mt asl, insolation is among the highest in the world but the temperature varies more than 30 degrees between day and night. At the community of Livitaca (Cuzco), the association “Ingegneria Senza Frontiere” is working on a project of bioclimatic architecture. In this context, it is devised a low cost drainback solar heating system, which can accumulate the heat picked up during the day by a rudimentary solar collector within a system of thermal activation of the floor's mass. The study focuses on the collector's design suitable for the aim: the temperature to be reached at its output is approximatively 30 C, therefore efficiency required is low.
