Abstract

The purpose of the present work was to investigate of cooling in the air conditioning room working concurrently with air discharge and air inlet. The venue is in a kitchen located at INTI Subang Culinary Department, Malaysia. The Kitchen air temperature, pressure, air flow and relative humidity was varied depending on different actions taken. For an example, with or without the stoves operating, how many stoves are operating together, with or without the door closed, how many students are practicing cooking and how many students are practicing cooking and how many students are using the refrigerator, these are all the condition that will affect the temperature, pressure, air flow and relative humidity inside the kitchen. Moreover, the changing rules of indoor thermal environment have an impact on human thermal comfort. Also, while investigating air conditioning system, air discharge and air inlet, an investigation of how these system affects human health and thermal comfort of air-conditioned room have attracted attentions from the public. So, it is necessary to determine the effect of this system towards human. An experimental investigation in the kitchen will be carry out Stage 2, these results from the investigation are used to compare with the simulation results under the same condition. After comparing the result from the experiment and simulation and both of them are correct, a forecast of the condition inside the kitchen will be conducted. With proper schematic, grid, mesh and correct boundary condition, we can predict different thermal condition inside the kitchen by using different value of the parameter. Some paperwork of reviewing journal and determining useful parameter and boundary condition are included here. In Stage 2, there are total 5 different case studies conducted inside the kitchen which are Kitchen Case 1 - Both Windows and Doors Open (Additional window), Kitchen Case 2 - doors Close and Windows (Additional Windows), Kitchen Case 3 - Both Doors and Windows Close, Kitchen Case 4 - With additional Ventilation System and Kitchen Case 5 - Exhaust with Half Close Valve. With these case studies, Iam able to predict the indoor thermal condition by using ANSYS 18.2 simulation software
