Experimental study of R450A drop-in performance in an R134a small capacity refrigeration unit
(Elsevier, 2017-08)
The Kigali amendment to the Montreal Protocol has highlighted the hydrofluorocarbons (HFCs) phase out as a priority to reduce the future global mean temperature increase. R134a is the most abundant HFC in the atmosphere ...

(Universitat per a Majors de la Universitat Jaume I, 2016)
The repair and rehabilitation of our house rely heavily on the particular interest of owners/users and climatic zones or regions. They also depend on the skills and tools available to facilitate this work. Nowadays, Europe ...
Experimental evaluation of a CO2 transcritical refrigeration plant with dedicated mechanical subcooling
(Elsevier, 2016-09)
CO2 transcritical refrigeration cycles require optimization to reach the performance of conventional solutions at high ambient temperatures. Theoretical studies demonstrated that the combination of a transcritical cycle ...
Experimental analysis of R-450A and R-513A as replacements of R-134a and R-507A in a medium temperature commercial refrigeration system
(Elsevier, 2017-09)
This work presents the experimental evaluation of R-513A (GWP = 573) and R-450A (GWP = 547) as R-134a (GWP = 1301) drop-in replacements and as R-507A (GWP = 3987) retrofits in a commercial direct expansion refrigeration ...
Numerical investigation of the effect of viscosity in a multistage electric submersible pump
(Taylor & Francis, 2017-02-04)
Electric submersible pump (ESP) systems are commonly used as an artificial lift technique by the petroleum industry. Operations of ESPs in oil wells are subjected to performance degradation due to the effect of oil viscosity. ...
The determination of waste generation and composition as an essential tool to improve the waste management plan of a university
(Elsevier, 2016-07)
When many people work in organized institutions or enterprises, those institutions or enterprises become big meeting places that also have energy, water and resources necessities. One of these necessities is the correct ...
The connection between the heat storage capability of PCM as a material property and their performance in real scale applications
(Elsevier, 2017-06)
Using phase change materials (PCM) for Thermal Energy Storage, the most important material property is their heat storage capability, usually given as h(T). Ideally, h(T) changes suddenly at a single temperature. However, ...
A comparison between the modeling of a reciprocating compressor using artificial neural network and physical model
(Elsevier, 2015)
This article presents the development, validation, and comparison of two methods for modeling a reciprocating compressor. Initially, the physical mode is based on eight internal sub-processes that incorporate infinitesimal ...
