Condensation heat transfer performance of six brazed type parallel flow condensers (PFHXs) were investigated, and were compared with a double-row Φp9.52mm fm-and-tube heat exchanger (CTHX) under the same testing condition. Pressure drop of airside, condensation capacity and comprehensive condensation performance were plotted in curves for comparison. The test results showed that: PFHXs had the characteristics of high comprehensive condensation performance and high condensation capacity per unit volume, the condensation capacity per unit face area of the PFHXs was higher than or equivalent to that of the CTHX under the same testing condition.
