Abstract: |
To improve energy efficiency in industrial refrigeration systems, a heat recovery device was designed and installed on a model system. Based on theoretical analysis, the system’s performance was evaluated under two operating conditions: with and without heat recovery. After the model was fabricated, experiments were conducted to measure inlet and outlet parameters over specific time intervals and operating conditions. The collected data were analyzed and compared using simulation methods to identify key factors influencing performance. Results showed that incorporating a heat recovery device increased the coefficient of performance (COP) from 3,0 to 3,44 and reduced the actual ice-making time by approximately 15 minutes compared to the system without heat recovery. This demonstrates a significant reduction in power consumption, with experimental results consistent with theoretical predictions. |

Abstract: |
The objective of this research is to apprehend through an exploratory qualitative study, the loyalty practices of commercial banks in Côte d'Ivoire.
The thematic content analysis of the accounts of interviews with 7 bankers shows that customer loyalty is achieved according to a customer relationship management approach in which the main actor is the customer advisor. Based on customer segmentation carried out mainly on the basis of income, banks set up loyalty programs in order to optimizecustomer relations and improve financial performance. |
