PURPOSE:To improve the performance of condensing heat transmission of a condenser for non azeotropic mixture by promoting condensation of low boiling component over the whole heat transmission surface of the condenser. CONSTITUTION:Liquid which has low boiling component concentration 22 is brought into contact with low boiling component gas 24 actively by forming a film of the liquid which has low low-boiling component concentration 22 over the whole heat transmission surface 20 by injecting the liquid which has low low-boiling component concentration 22 through an inlet.
