Abstract

A steady-state computer simulation based on fundamental principles was developed to model air-cooled condensers. It consists of dividing the total condenser length into a few segments which are further divided into several modules, as in the tube-by-tube approach. Air and refrigerant heat transfer coefficients, as well as refrigerant pressure drop, were calculated using the existing correlations. The model provides increased flexibility in terms of flow circuitry and refrigerant type. An experimental test matrix covering a wide range of conditions was used to validate the simulation. Two typical cross-flow condensers were modeled and the error between experimental and calculated condenser capacities obtained with refrigerant R-134a was within 10%.
