| Abstract: | Present study simulates condensation heat transfer and pressure drop characteristics of R407C, when it is charged in
an air-cooled fin and tube condenser designed for R22 utilizing the local method of analysis. In this analysis, heat exchanger
is divided into segments or multiple control volumes, with the outlet of one control volume being the inlet to an adjacent
control volume, and so on. The properties of refrigerants viz., liquid as well as vapour phase density, viscosity, specific heat,
thermal conductivity and enthalpy are calculated using subroutines from National Institute of Standards and Technology
software package REFPROP. Refrigerant side as well as airside heat transfer and pressure drop are computed using reported
correlations. |
