This paper presents an influence of heat flow from high temperature refrigerant to low temperature refrigerant through fins by thermal conduction. For estimating the influence, we applied thermal network method that can consider refrigerant quality distribution in the heat exchanger. At a same time, for verifying the estimation, an experiment was performed with 2 row-2 pass heat exchanger. Prediction shows that heat transfer capacity of a condenser is reduced by 3% for a simple 2 row-2 pass heat exchanger by heat conduction in fins. By comparison between the experimental results and the predicted results, it was proved that predicting error was within 1% for condenser capacity.
