Maturity of the photovoltaic (PV) technology is emphasized by the numerous types of applications encountered nowadays. One of the most interesting applications, however, is the use of PV units for pumping water, i.e. the implementation of PV pumping systems (PVPSs) in order to cover both...

An experimental technique is presented to non-intrusively measure the quasi-instantaneous aerodynamic loads and surrounding pressure field for a turbine by using particle image velocimetry (PIV). The PIV measurements provide the velocity flow field needed to calculate the pressure field around...

Among the non-linear loads used in household, Compact Fluorescent Lamps (CFLs) and LED lamps are becoming more widespread, while incandescent lamps are intended to be replaced by these types of lighting devices. LEDs and CFLs are significantly more efficient and economical than incandescent...

Simulations to evaluate energy demand for heating and cooling and thermal comfort are becoming more and more common place in the building design process, at least in the most complex cases. In all detailed or simplified calculations, to analyse heat transfer to and from a building, several input...

The progress met in the world market of photovoltaics underlines the maturity of investments realized, guarantees the reliability of the technology utilized and designates the variety of applications in covering the energy demands of both stand-alone and grid connected consumers. Concerning...

The present work investigates the effectiveness of an innovative procedure to calculate the global real sky irradiance of a mountain urban region, the city of Trento (Italy). The proposed methodology improves the predictive Bird’s real-sky model by introducing in it both atmospheric...

An experimental and analytical investigation for the temperature distribution prediction of a three-phase bubble-type direct-contact condenser conducted, using a short Perspex column with 4 cm internal diameter and 70 cm height as a direct contact condenser. Vapour pentane and water were...

This paper presents the evaluation of the performance of a ground source heat pump system monitored plant providing heating/cooling to an office building located in the Universitat Politècnica de València in Spain. The system was designed using GLHEPRO software and it has been monitored since...
