Design and simulation of finned-tube heat exchangers using pure and mixed refrigerants.

Author(s) : BENSAFI A., BORG S.

Summary

A computational model for the detailed design of finned-tube heat exchangers is presented. Coils are discretised into tube elements for which the governing equations are solved using local values of temperature, pressure, physical properties and heat transfer coefficients. Single phase, condenser and evaporator cases can be treated using water, R22, R134a, and various refrigerant mixtures based on R32, R125, and R134a. The software can handle non-conventional coil circuits with different numbers of inlets and outlets, non-uniform air distribution at coil inlet face, using smooth and internally finned tubes.
