In this research, an absorption cooling system of nominal capacity 10 [kW] has been built and tested; it works by different sources of heat and by different working fluids, it is equipped with adequate sensors for measuring temperature, flows and pressures in multiple locations. The features of operating the machine for air conditioning has been determined, analyzed and discussed with the working fluid “water-Lithium Bromide” by different boundary conditions. The results of experiments proved the possibility of the work of solar absorption cooling machine continuously at the heating temperature of the generator of 60 [°C] producing cold water in the evaporator at a temperature less than 10 [°C] with a coefficient of performance 0,5 and this enables us to use Simple and cheap flat solar collectors for the operation of the machine.
