| Summary: | To reduce the power consumption of air conditioning system, we can
optimize the flow rate in air conditioning system. Thus, a device created to measure
the flow rate to optimize the flow rate and increase the efficiency of the air
conditioning system. The triangular obstacle will be simulated and will be compared
with actual model to verify the setup of the experiment . In experiment, the optimum
obstacle will be tested to determine variable such Sound power level (Db),
Volumetric flow rate and Air velocity experiment, from microphone sound intensity
generated in microphone and Fast Fourier Transform (FFT) used to transform
intensity against frequency of sound wave graph. A peak of intensity exists at a
certain frequency. Different flow rate gave different peak intensity of sound at same
frequency of 2194Hz. After the experiment calibration graph of intensity of sound
(dB) against flow rate at a specified frequency obtained as reference when using the
sound acoustic to determine the velocity /flow rate in air conditioner in a more
economical way |
