Résumé

The flow pattern of the refrigerant in an evaporator-inlet pipe is a very important factor for determining the type of refrigerant-induced noise because the shape and size of the bubble are different according to the flow pattern in the pipe. In this study, the relations between refrigerant-induced noise and flow patterns are discussed. The flow patterns of the fluid in horizontal and vertical pipes were also estimated using Hewitt, Taitel-Dukler and Oshinowo-Charles maps. The refrigerant-supplying equipment was used to monitor the characteristics of the flow in the experiments. The shape and layout of evaporator-inlet pipe were suggested not to be the intermittent flow pattern. The noise level radiated from the refrigerator could be reduced by about 2-5 dB in the frequency range from 315 Hz to 3.15 kHz.
