Feasibility study and performance evaluation of low capacity water-LiBr absorption cooling systems functioning in different Algerian climate zones

A performance analysis was carried out on water-LiBr absorption chillers performing in the five different climate zones in Algeria. A 17.6 kW single-effect and a 16 kW double-effect commercial absorption chillers were simulated. In climate zones E1 and E2, the single-effect and double-effect chillers supplied 37% and 91%, respectively, of their nominal capacity to produce chilled water at 7 degrees C. In the hot climate zones E3, E4 and E5, it was not feasible for either of the chillers to produce chilled water at 7 degrees C. By increasing the chilled water temperature to 12 degrees C both absorption chillers were able to operate in climate zones E3 and E4. The single-effect chiller reached 45% of its nominal capacity in zone E3 and 33% in zone E4. The double-effect chiller delivered 80% of its nominal capacity in both climate zones. Neither of the chillers was able to operate under the thermal conditions of climate zone E5. (C) 2017 Elsevier Ltd and IIR. All rights reserved.
