Heat rejection from an absorber by the vapor absorption refrigirator, is one of the most affecting processes on the system performance, specially for an autonomous operating system. A proposed absorber heat extracting technique is experimentally investigated to define the effect of the operating parameters upon the system performance. The proposed technique makes use of the gravity assisted heat pipe of a special form.It was observed that the evaporator filling ratio, for the heat pipe has an optimum value which depends mainly upon the difference between the operating temperatures for the evaporator and condenser.
