A physically based computer model for mobile air conditioning condensers using ozone-safe refrigerants.

Author(s) : ZIETLOW D. C., RAGAZZI F., PEDERSEN C. O.

Summary

A steady-state computer simulation based on fundamental principles was developed to model air-cooled condensers. Air and refrigerant heat transfer coefficients and 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 R134a was within 10%.
