The aim of this work was to evaluate the performance of a 35 kW LiBr-H₂O absorption machine driven by 72 m² heat pipe evacuated tube collector with a gas backup system, by analyzing the COP based on the manufacturer's specifications. The results from this study showed that actual average COP of the system was 0.33 while the maximum and minimum values were 0.50 and 0.17 respectively. These results were obtained based on the average collector efficiency and the solar fraction of 0.55 and at an ambient temperature of 32 ¡ãC.
