The refrigerant flow noise from the A/C distribute pipe line shapes

A/C 실내기 배관 형상에 따른 냉매 유동 소음 특성에 관한 연구

The distribution control of refrigerant flow is one of the basic technique to enhance system efficiency. However, if engineers forget to control the refrigerant flow speed in all operation range, refrigerant flow mal distribution becomes a noise source. The refrigerant flow noise should be checked and controlled at the lowest air flow mode which is the most silent mode and frequently used in night time.
