One of the most new methods of solar applications are the adsorption refrigeration methods, which can be powered by solar energy or waste heat. A hybrid adsorption refrigeration unit was designed, built and tested in this work, on January, 2008. A series of test on the solar collector was achieved to simulate the temperature of hot water that used to heat the unit generator of the field unit. Also from the field adsorption unit using an adsorption pair active carbon and methanol, it was found that there is an optimum generator temperature at which the cycle COP reach max. The cycle COP was varied from 0.07 to 0.3. It was found that it can chill one liter of water from an initial temperature of 35°C also a formation of 1cm thick ice around the evaporator wasobtained, when the mass of active carbon was 1.25kg and methanol concentration of 0.07 kg(meth.)/kg(A.C.).
