Optimization of the Hose-Based Low-Cost Solar Collector
(IBIMA Publishing, 2013-12)
The performance of solar collectors based on plastic hoses is noticeably improved by using a thermal-hydraulic modeling experimentally validated. This model allows us to optimize the main parameters of collector (length ...
Assessment of integrated performance and roof geometry for solar energy
(OPEN HOUSE INTERNATIONAL ASSOCIATION, 2016-01-01)
The roofs of houses located at middle latitudes receive significant solar radiation useful to supply their own energy demands and to feed back into the urban electricity network. However, solar panels should be properly ...

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 ...
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 ...
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 ...
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 ...
Analisys of thermal efficiency of a modified solar collector type evacuated tube
(2014)
The need of renewable energy sources due to climate change and thus the search for clean energy sources, justify the growing investment on new types of solar collectors. The research has contributed to this expansion in ...
A review of the state-of-the-art of solar thermal collectors applied in the industry
(2022)
The energy consumption associated with the industry sector represents 38% of the global energy demand, being an important aspect that marks the development of a country. In this sense, it is extremely important to diversify ...
