On the validity of a design method for a solar-assisted ejector cooling system
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
A solar-assisted ejector cooling system is simulated in order to investigate the validity of a design methodology. Hourly simulation results allow for Computing the solar fraction, in cases when the cooling capacity of the ...
Diurnal evolution of the hourly diffuse solar radiation incident on tilted surfaces in Southeast of Brazil
(2013)
Evaluation has been made on the monthly and annual average diurnal evolution of the hourly diffuse radiation as well as its radiometric fractions on surfaces inclined at 12.85, 22.85 and 32.85° to face North, in climate ...
Global, diffuse and direct solar radiation at the surface in the city of Rio de Janeiro: Observational characterization and empirical modeling
(Elsevier B.V., 2016-06-01)
The city of Rio de Janeiro and others 18 cities compose the Metropolitan Area of Rio de Janeiro. The main objective of this work is to characterize observationally the diurnal and seasonal evolution of the solar radiation ...
Modeling hourly and daily fractions of UV, PAR and NIR to global solar radiation under various sky conditions at Botucatu, Brazil
(Elsevier B.V., 2009-03-01)
In this analysis, using available hourly and daily radiometric data performed at Botucatu, Brazil, several empirical models relating ultraviolet (UV), photosynthetically active (PAR) and near infrared (NIR) solar global ...
