| Summary: | Commercial kitchen hood ventilation system is a device used to capture and filtered the
plumes from cooking activities in the kitchen area. In the recent years, it is very important in an
industrial sector such as restaurant and hotel to provide hygiene food. The purpose of this study is
to identify flow characteristics in the commercial kitchen hood ventilation system and to observe
the effect of capture jet technology. The ANSYS 14.5 (FLUENT) Software is the tool used to
simulate the kitchen hood system with capture jet and without capture jet technology. The design
model has a dimension of 700 mm width, 1600 mm length and 555 mm height. The comparisons
are made between Water Wash/Water Mist kitchen hood with capture jet and without capture jet, in
order to observe the effect of the capture jet technology through flow characteristics analysis. Three
different cases are tested which are Case A (1.071 m/s), Case B (0.871 m/s) and Case C (0.671 m/s)
set at inlet capture jet. Results show that kitchen hood with capture jet technology has improved the
flow characteristics in the kitchen hood system which helps to increase the average velocity and
control flow in kitchen hood system. Case A with the velocity of 1.071 m/s has the highest average
velocity compared to the Case B, 0.871m/s and Case C, 0.671m/s. Overall Case A provided better
flow characteristic based on its characteristic of spreading the fresh air in workspace area. The
more spreading of fresh air, it will cover more area in kitchen space thus its helps to provide better
thermal condition in the kitchen space. It can be conclude that the inlet capture jet velocity plays an
important role in order to help the system efficiently vent out the plumes from kitchen area at the
same time to provide better Indoor Environmental Quality (IEQ) in kitchen space. |
