A new direct expansion solar assisted ejector-compression heat pump cycle is present. The performance of the new cycles is investigated by simulation method. The new cycle significantly outperforms the basic ejector enhanced heat pump cycle. The new cycle has two operation modes to be chosen according to the solar radiation. Increasing the solar radiation intensity benefits the performance of the new cycle.
