Optimum performance of an endoreversible heat engine-driven heat pump cycle, based on a combination of an absorption cycle with a vapour and ejector compression cycles is investigated. This combination increases the performance of the conventional ejector and absorption cycles and provides high performance for heating. The analysis show that the combined heat pump cycle has a significant increase in system performance over the heat engine-driven vapour compression or absorption heat pump cycle and heat engine-driven combined vapour compression and absorption heat pump cycle.
