The various types of condensing equipment are described including shell-and-tube for power and process applications, plate, spiral, plate-fin, air-cooled and direct-contact. Advice on the choice between the types is given. Methods available for the design and check-rating of these exchangers are given, with particular emphasis on the shell-and-tube which is the most common type. These methods build upon the detailed theories and correlations for individual condensing processes, which are described in previous chapters. An important calculation step is the determination of the mean temperature difference and mean overall coefficient from their local values. This problem is therefore discussed in some detail. Possible reasons why condensers fail to operate as expected are noted.
