摘要：

A new PCHE with an S-shaped fin configuration was applied to a hot water supplier in which cold water of 7 degrees C is warmed to 90 degrees C through heat-exchange with supercritical CO2 of 118 degrees C and 11.5 MPa pressure. The fin and plate configurations were determined using 3D CFD simulations for the CO2 side and H2O side and the thermal-hydraulic performance of hot water supplier was evaluated. Compared with a hot water supplier that is currently used in a residential heat pump, the new PCHE provides about 3.3 times less volume; and lower pressure drop by 37% in the CO2 side and by 10 times in H2O side.
