Performance analysis of ejector absorption heat pump using ozone safe fluid couple through artificial neural networks
(Pergamon-Elsevier Science Ltd, 2004)Thermodynamic analysis of absorption thermal systems is too complex because the analytic functions calculating the thermodynamic properties of fluid couples involve the solution of complex differential equations and ... -
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 ... -
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 ... -
Pimli bağlantılarda çatlak ilerleme yönünün sonlu elemanlar metodu ile bulunması
