Artificial neural network analysis of heat pumps using refrigerant mixtures
(Pergamon-Elsevier Science Ltd, 2004)
In this study, we have investigated the performance of a vapor compression heat pump with different ratios of R12/R22 refrigerant mixtures using artificial neural networks (ANN). Experimental studies were completed to ...
An experimental and numerical investigation of strength characteristics of carbon-epoxy pinned-joint plates
(Elsevier Sci Ltd, 2004)
An experimental and numerical study has been carried out to investigate the strength of a pinned-joint carbon epoxy composite plate with [0degrees/45degrees/-45degrees/90degrees]s and [90degrees/45degrees/-45degrees/0degrees]s ...
Performance comparison of CFCs with their substitutes using artificial neural network
(John Wiley & Sons Ltd, 2004)
In order to decrease global pollution due to chlorofluorocarbons (CFCs), the usage of HFC- and HC-based refrigerants and their mixtures are considered instead of CFCs (R12, R22, and R502). This was confirmed by an international ...
Estimation of solar potential in Turkey by artificial neural networks using meteorological and geographical data
(Pergamon-Elsevier Science Ltd, 2004)
Turkey is located at the Mediterranean at 36degrees and 42degrees N latitudes and has a typical Mediterranean climate. The solar energy potential is very high in Turkey. The yearly average solar radiation is 3.6 kW h/m(2) ...
Investigation of thermodynamic properties of refrigerant/absorbent couples using artificial neural networks
(Elsevier Science Sa, 2004)
This paper presents a new approach to determine the properties of liquid and two phase boiling and condensing of two alternative refrigerant/absorbent couples (methanol-LiBr and methanol-LiCl), which do not cause ozone ...
Energy and exergy analyses in a rotary burner with pre-calcinations in cement production
(Pergamon-Elsevier Science Ltd, 2004)
Cement production facilities are often located in rural areas and close to quarries, where the raw materials required for cement production are present, i.e. limestone and shale. Although energy analysis, based on the first ...
A study for estimating solar resources in Turkey using artificial neural networks
(Taylor & Francis Inc, 2004)
Turkey has sufficient solar radiation and radiation period for solar thermal applications since it lies in a sunny belt between 36degrees and 42degreesN latitudes. The yearly average solar radiation is 3.6 kWh/m(2) day, ...
Performance prediction of a vapour-compression heat-pump
(Elsevier Sci Ltd, 2004)
The performance of the heat pump was predicted using a fuzzy-logic controller under various working-conditions and mixing ratios of R12/R22 refrigerant mixtures, instead of requiring an expensive and time consuming ...
A new approach to thermodynamic analysis of ejector-absorption cycle: artificial neural networks
(Pergamon-Elsevier Science Ltd, 2003)
Thermodynamic analysis of absorption thermal systems is too complex because of analytic functions calculating the thermodynamic properties of fluid couples involving the solution of complex differential equations. To ...
The effect of stacking sequence of carbon epoxy composite laminates on pinned-joint strength
(Elsevier Sci Ltd, 2003)
In this paper, an experimental study regarding the determination of the safe as well as the maximum bearing strengths of a pinned-joint carbon epoxy composite laminate with [0degrees/45degrees/-45degrees/90degrees]s and ...
