The pulsed-flow design: A new low-cost solar collector
(Pergamon-Elsevier Science Ltd, 2016-03)
A new pulsed-flow design of hose-based solar collector is presented, which uses a long hose connected to district-grid water in the same way that the basic hose design does. But on contrary that this last, here the exit ...
Residential solar thermal performance considering self-shading incidence between tubes in evacuated tube and flat plate collectors
(2021)
The performance of solar thermal technology under high-altitude equatorial climatic and solar path conditions has not been determined. Evacuated tube solar collectors are more efficient than flat plate collectors in cold ...
Modified vacuum tubes for overheating limitation of solar collectors: A dynamical modeling approach
(Pergamon-Elsevier Science Ltd, 2018-09)
In this paper are presented two designs of vacuum tubes designed to avoid the overheating of solar collectors. As we discuss, this behavior must be studied by considering the collector's nonlinear dynamic, which is numerically ...
Linear Fresnel solar collector prototype: Artisanal system for the production of hot water and/or water vapour
The development of a linear Fresnel solar collector prototype is discussed, highlighting the use of direct solar heat radiation for water heating and/or steam production as an alternative to conventional water-heating ...
Numerical analysis of a modified evacuated tubes solar collector
(2012)
The need for renewable energy sources, facing the consequences of Climate Change, results in growing investment for solar collectors’ use. Research in this field has accompanied this expansion and evacuated tube solar ...

Análise experimental de diferentes configurações de termossifões para aplicação em coletor solar
(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilPrograma de Pós-Graduação em Engenharia MecânicaUTFPR, 2017-12-15)
Solar collectors assisted by thermosyphons or also called vacuum solar collectors, are viable alternatives for the use of water heating and act directly on a significant portion of the energy consumption. They are more ...
A New Low-Cost Plastic Solar Collector
(Hindawi Publishing Corporation, 2013-07)
An innovative solar collector based on a long plastic hose that is connected directly in series from the district water grid to consumption is presented. It takes advantage of plastic tubing to develop a simple self-construction ...
