The current analysis comprises the configuration of combined refrigeration system which is integration of a vapour compression and vapour absorption system. The integrated system is energized by a microgas turbine to generate cooling at the low temperatures. The waste heat from the exhaust of microgas turbine is used to drive the vapour absorption system while the vapour compression system is directly powered by the small gas turbine. The compression system is at the low temperature stage while the absorption system is at high temperature stage boost the performance of compression system. A computational thermodynamic analysis of the combined system is carried out using mass energy governing equations. It has been concluded on the basis of result obtained that the performance of combined refrigeration systems is higher and less energy consuming.
