New design of solar roof for household heating and cooling
(Pergamon-Elsevier Science Ltd, 2010-06)
A new design of solar roof is presented. It is a roof-integrated solar collector that is configurable by water redistribution. This way, this active system can provide household heating and cooling. Its thermal performance ...
Passive solar radiant system, SIRASOL. Physical-mathematical modeling and sensitivity analysis
(Pergamon-Elsevier Science Ltd, 2013-10)
When using passive solar heating systems, it is necessary to have available an Equator-facing facade on which to install them. Rooms without such a facade are not the best option for conventional passive solar heating ...
Introduction to the Application of Phase Change Materials under Tropical Climate of Panama
(2019 7th International Engineering, Sciences and Technology Conference (IESTEC)2019 7th International Engineering, Sciences and Technology Conference (IESTEC), 2016-10-09)
Phase change materials (PCM) are materials with the ability to store a large amount of energy (latent heat) during their change from solid to a liquid phase. This takes place at a certain melting temperature. Amid the ...
Full thermal-hydraulic and solar modeling to study low-cost solar collectors based on a single long LDPE hose
(Pergamon-Elsevier Science Ltd, 2017-06)
A comprehensive analysis of low-cost solar collectors based on a single long plastic LDPE hose resting on a roof and working by thermosiphon is performed. This lay-out involves two challenging issues, high hydraulic ...
Experimental and theoretical analysis of thermal solar collector systems for dhw in northern Italy
(RE&PQJ Editorial Committe, 2012-04)
Solar collectors performance evaluation has some established standards, represented by UNI 12976 and ISO 9806. Nevertheless, solar collectors are often installed as part of more complex Domestic Hot Water system (DHW). The ...
Calefacción solar en edificaciones con acumulación en gran reservorio de aguaSolar heating in buildings by using a large storage water tank
(Universidad de Chile. Facultad de Arquitectura y Urbanismo. Instituto de la Vivienda, 2018-08)
Este trabajo muestra la factibilidad de calefacción solar en Bariloche (3.600 grados-día/año, 8.4°C media anual) empleando colectores tipo heat pipe y almacenamiento en un reservorio de agua aislado y utilizarlo mediante ...
Heating houses by using vacuum-tube solar collectors and a small aboveground water tank: a cost-effective solution for maritime climates
(Taylor & Francis Ltd, 2019-11)
This work presents a simple dynamical solar-thermal modeling and cost-optimized solution for heating houses in maritime climates by using many vacuum-tube solar collectors together with one small well-insulated aboveground ...
Heat storage wall made of concrete and encapsulated water applied to mass construction social housing in temperate climates
(Elsevier Science SA, 2018-01)
In Argentina there is a serious housing shortage. The National State responds to this shortage in a quantitative rather than in a qualitative way, avoiding low maintenance architectural and technological solutions for this ...
Analytic modeling of parabolic trough solar thermal power plants
(Pergamon-Elsevier Science Ltd, 2017-07)
We derive, evaluate and validate comprehensive analytic modeling of the energy flows in parabolic trough solar thermal power plants. The analytic formulae are straightforward to implement and evaluate, relating to the heat ...
Estrés calórico: beneficios de los árboles en los sistemas ganaderos
(EEA Alto Valle, INTA, 2019)
En los últimos años se ha incrementado notablemente la producción ganadera en los valles del norte de la Patagonia, en sistemas bajo riego que incluyen la recría y la terminación a corral. En estos sistemas, en los que no ...
