Résumé

Condensation heat transfer performance of a louvered fin-and-flat-tube heat exchanger (FTHX) in single slab and in residential air-conditioning system were experimentally investigated, and were compared with fin-and-circular-tube heat exchangers (CTHX) under the same testing conditions. The test results showed that: FTHX had the characteristics of low pressure drop of air side, high pressure drop of refrigerant side and less refrigerant charge; the overall heat transfer performance of copper FTHX was higher than that of diameter 7 mm CTHX but a little lower than that of diameter 9.52 mm CTHX; the cooling capacity and EER of the residential air-conditioning system with FTHX were a little lower than those of the system with diameter 9.52 mm CTHX.
