Regenerative heat exchangers In a regenerative heat exchanger, the flow path normally consists of a matrix, which is heated when the hot fluid passes through it (this is known as the “hot blow”). This heat is then released to the cold fluid when this flows through the matrix (the “cold blow”). Regenerative Heat Exchangers...

Classification of Heat Exchangers by Construction heat exchangers are classified mainly by their construction, The first level of classification is to divide heat exchanger types into recuperative or regenerative. A Recuperative Heat Exchanger has separate flow paths for each fluid and fluids flow simultaneously through the exchanger...

Cross flow heat exchangers are intermediate in efficiency between counter current flow and parallel flow exchangers. In these units, the streams flow at right angles to each other

In co current flow heat exchangers, the streams flow parallel to each other and in the same direction This is less efficient than counter current flow but does provide more uniform wall temperatures. Process 1. Process fluid assignments to shell side or tube side. 2. Selection of stream temperature specifications. 3. Setting shell side and...

Counter flow exchanger in which the two fluids flow parallel to each other but in opposite directions. This type of flow arrangement allows the largest change in temperature of both fluids and is therefore most efficient (where efficiency is the amount of actual heat transferred compared with the theoretical maximum amount of heat that can...
