CFD ANALYSIS OF CONDENSER IN A DOMESTIC AIR CONDITIONER
CFD simulation of a 1-row condenser in a domestic air conditioner is made. 2D models, with uniformly constant fin temperature overestimate significantly the heat transfer coefficient. 3D models, taking into account tube effects, conjugate heat transfer and conduction through the fin are in better agreement with the experimental results. A condenser experiment system is designed and built to validate the CFD result. Calculations are performed for different air frontal velocities and different condensation temperature. Even if an offset(less than 9％) of between CFD calculations and the experimental results, the trends are comparable and CFD study permits to reach local information, leading to better understanding of the physical phenomena involved in compact heat exchangers. The prediction outside the experiment range is discussed by performing “numerical experiment. It is found that there is optimum fin space when other structure parameters of the tube-fin condenser are given, and there is optimum tube space when other structure parameters of the tube-fin condenser are given.
