Effect of inlet configuration on the refrigerant

In parallel flow, the hot and cold fluids flow in the same direction and therefore enter the exchanger on the same end and exit the exchanger on the same end. In counter flow, the two fluids flow in opposite directions and thus enter the exchanger and exit the exchanger from opposite ends. Cross flow heat exchangers will not be analyzed as a part of this laboratory experiment.

Why is a counter flow heat exchanger better than a

Thus, the parallel flow type heat exchanger of the invention is constructed so that parallel flows passing through a plurality of flat tubes 14 are established between the inlet header pipe 1 and the outlet header pipe 1. Referring to FIG. 1, reference numerals 16, 17 designate side plates and 18, 19 respectively designate inlet and outlet joints.

CFD Analysis and Performance of Parallel and Counter Flow

Parallel Flow Heat Exchanger The figure below shows a schematic of a parallel-flow heat exchanger along with temperature distribution for the hot and cold fluids. We treat the heat exchanger as insulated around the outside so that the only heat transfer is between the two fluids. As one would expect, the cold fluid (bottom curve) heats up and the hot fluid (top curve) cools down. Where: T hi
