The article refers to the learning process of the vaporous condensation occurs in the heat exchanger equipments through the study of the motion of the second phase vaporousness occurs when the heat exchange process. To study the process of dissipation of heat at the time set up film condensation from vapour when flow tube motion in the horizontal, vertical pipes and horizontal beam tubes, giving the method for calculating heat transfer in the condensation process. In addition, the paper also studies factors affecting the heat transfer process when condensation so that give the choices made, the necessary measures in the calculation and design applied to the heat exchange equipment when condensing.
