Effect of relative humidity on solar potential
Sozen, A; Arcaklioglu, E (Elsevier Sci Ltd, 2005)In this study, the effect of relative humidity on solar potential is investigated using artificial neural-networks. Two different models are used to train the neural networks. Meteorological and geographical data (latitude, ... -
Estimation of solar potential in Turkey by artificial neural networks using meteorological and geographical data
Sozen, A; Arcaklioglu, E; Ozalp, M (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) ... -
Forecasting based on neural network approach of solar potential in Turkey
Sozen, A; Arcakhoglu, E; Ozalp, M; Caglar, N (Pergamon-Elsevier Science Ltd, 2005)As Turkey lies near the sunny belt between 36 and 42 degrees N latitudes, most of the locations in Turkey receive abundant solar energy. Average annual temperature is 18-20 degrees C on the south coast, falls down to 14-16 ... -
Formulation based on artificial neural network of thermodynamic properties of ozone friendly refrigerant/absorbent couples
Sozen, A; Arcaklioglu, E; Ozalp, M (Pergamon-Elsevier Science Ltd, 2005)This paper presents a new approach based on artificial neural networks (ANNs) to determine the properties of liquid and two phase boiling and condensing of two alternative refrigerant/absorbent couples (methanol/LiBr and ... -
Investigation of thermodynamic properties of refrigerant/absorbent couples using artificial neural networks
Sozen, A; Ozalp, M; Arcaklioglu, E (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 ... -
A new approach to thermodynamic analysis of ejector-absorption cycle: artificial neural networks
Sozen, A; Arcaklioglu, E; Ozalp, M (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 ... -
Performance parameters of an ejector-absorption heat transformer
Sozen, A; Arcaklioglu, E; Ozalp, M; Yucesu, S (Elsevier Sci Ltd, 2005)Ejector-absorption heat transformers (EAHTs) are attractive for increasing a solar-pond's temperature and for recovering low-level waste-heat. Thermodynamic analysis of the performance of an EAHT is complicated due to the ... -
Performance prediction of a vapour-compression heat-pump
Sozen, A; Arcaklioglu, E; Erisen, A; Akcayol, MA (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 ... -
Prospects for utilisation of solar driven ejector-absorption cooling system in Turkey
Sozen, A; Ozalp, M; Arcaklioglu, E (Pergamon-Elsevier Science Ltd, 2004)Solar assisted refrigeration appears to be a promising alternative to the conventional electrical driven units. The main advantages of solar assisted refrigeration systems concern the reduction of peak loads for electricity ... -
Solar potential in Turkey
Sozen, A; Arcaklioglu, E (Elsevier Sci Ltd, 2005)Most of the locations in Turkey receive abundant solar-energy, because Turkey lies in a sunny belt between 36degrees and 42 degreesN latitudes. Average annual temperature is 18 to 20 degreesC on the south coast, falls to ... -
Solar-energy potential in Turkey
Sozen, A; Arcaklioglu, E; Ozalp, M; Kanit, EG (Elsevier Sci Ltd, 2005)In this study, a new formula based on meteorological and geographical data was developed to determine the solar-energy potential in Turkey using artificial neural-networks (ANNs). Scaled conjugate gradient (SCG) and ... -
Turkey's net energy consumption
Sozen, A; Arcaklioglu, E; Ozkaymak, M (Elsevier Sci Ltd, 2005)The main goal of this study is to develop the equations for forecasting net energy consumption (NEC) using an artificial neural-network (ANN) technique in order to determine the future level of energy consumption in Turkey. ... -
Use of artificial neural networks for mapping of solar potential in Turkey
Sozen, A; Arcaklioglu, E; Ozalp, M; Kanit, EG (Elsevier Sci Ltd, 2004)Turkey has sufficient solar radiation intensities and radiation durations for solar thermal applications since Turkey lies in a sunny belt, between 36degrees and 42degrees N latitudes. The yearly average solar-radiation ...
