Abstract


This paper presents a field study of indicators of the performance of absorption refrigerating systems in the  Sudano-Sahelian region of Cameroon. A modeling of various components of the system is performed in order to  choose the technology best adapted for the region. Based on the characteristics from the manufacturers,  four absorption chillers were studied; namely: EAW Schüco LB 15 and 30; Rotartica Solar 045 and Sonnenklima  Suninverse. The model of Kühn and Ziegler and meteorological data of the city of Maroua ((14.33  °E, 10.58 °N) were used to assess the coefficient of the performance (COP) of these machines. Results  showed that the Sonnenklima Suninverse technology is best suited for the climatic conditions of the Sudano-Sahelian region with COP values between 1.5 and 3.5.

Keywords: Solar cooling; Absorption chillers; Performance indicators; Sudano-Sahelian region.
