A waste-heat activated vapour ejector refrigeration cycle for automotive air-conditioning applications was studied and analysed. Conservation equations of continuity, momentum, and energy were solved simultaneously, and pressures, temperatures, enthalpies, and mass flow rates at various points in the cycle were computed. The ejector system energy requirements were compared to the available energy in the exhaust gas and the engine coolant. It was found that the engine's coolant energy is superior to that of the exhaust heat energy in activating the system, for most of the engines considered. When considering the exhaust heat, only partial cooling loads up to 1.25 tons of refrigeration could be accomodated. During start-up, when the coolant temperature is not high enough, a supplemental heating system would be necessary.
