NH3 condensation in a plate heat exchanger
Experimental investigation on flow patterns, heat transfer and frictional pressure drop
This paper investigates NH3 condensation in a plate heat exchanger by visualizing the flow patterns and measuring heat transfer coefficients and frictional pressure drop. Visualization experiments were conducted between 20 and 100 kgm−2s−1. Ful ...
The heat transfer coefficients (HTCs) of NH3 are higher than of HFCs and hydrocarbons during the condensation within plate heat exchangers (PHEs) mainly due to its favorable transport properties. NH3/H2O has a large temperature glide, and its h ...
