Summary

Recently, the noise caused by the refrigerant fluid is spotlighted due to the demand of low noise home and office air conditioners. Especially, reduction of refrigerant fluid noise and vibration noise generated from throttle in the expansion valve is becoming important. Therefore in this study it is intended to resolve fluctuating phenomena of fluid, which may be the cause of noise, by flow visualization and measurement of fluid pressure and temperature at throttle valves, focusing on two-phase flow of refrigerant fluid.
