초록

Test models which have geometrical similarities with a real room air conditioner (RAC) have been manufactured including visualization windows so that a laser beam can pass through a cross flow fan. Then, flow distributions of the RAC have been investigated using a visualization technique such as a Particle Image Velocimetry (PIV) to analyze an efficiency and noise of the RAC. Pitot tubes have also been used to measure the flow velocity inside the RAC with various positions to confirm the measurement accuracy of the PIV technique. The measured flow velocities have been analyzed and new designs of the RAC have been proposed to improve the efficiency and to reduce the noise for the RAC in this study.
