An experimental study was performed to investigate the flow characteristics of the freezer room and cold storage room in a home refrigerator. As multi-point simultaneous velocity acquisition, 2-D PIV system based on the two-frame gray level cross correlation method was adopted using PC image-grabber and simple video system. Image intensifier CCD camera to cope with the illumination problem was arranged for the accurate PIV measurement of the unsteady flow field. And all PIV procedures including animation jobs that give macroscopic and quantitative description of complex flow fields such as the temporally continuous distribution of the instant vectors, kinetic energy, vorticity and turbulent intensity were displayed in a real-time sense. As a result, both the quantitative analysis and qualitative visualization by artificial particle-injection to the outlet region of a cooling air supply fan revealed that very complicated turbulent behavior was dominant in the separate region and around obstacles existing along the cooling air passage.
