| dc.description.abstract | Heat exchangers have been commonly used
in industrial processes such as thermal power plant,
chemical process, air conditioner device, refrigerator,
even in some bigger energy processes like oil and gas.
The performance of a heat exchanger is not
permanently the same during daily and even
annually uses whereas one of the most common
causes is the fouling factor. In this research, the
performance of a laboratory scale heat exchanger
was observed by the inlet and outlet temperature of
hot oil and cold water fluids based on characteristic
of fouling factor. The flow rates were kept constant
at 0.72 m
3
/hour for shell and 0.468 m
3
/hour for tube.
The observation time was at 06.00 am, 12.00 am,
18.00 pm, 24.00 pm every day for six respective days.
The result shows that ΔT
changes irregularly
during the observation while the fouling factor
increases regularly and decreases significantly by the
end of the observation. | en_US |
