This paper reports results of comparative experiment between two kinds of configurations of hybrid power and refrigeration cycle which employs ammonia-water mixture (AWM) as working fluid. The hybrid cycle mainly consists of an ammonia absorption refrigerator and an AWM turbine cycle ; these are connected by several pipelines. One configuration (configuration-1) takes higher mass fraction solution out from low-pressure condensor. The other configuration (configuration-2) takes it from high-pressure condensor. The experiment were carried out by changing the flow rate of higher mass fraction solution from the AWM turbine section to the refrigerator section. Focusing on the refrigerator section, both configurations achieved higher COP than the separate opperation. Othrewise, thermal efficiency of the AWM turbine section by configuration-2 decreased about 29% at a minimum. Thermal efficiency by configuration-1 rather increased about 77% at a maximam.
