What are the JKR requirement for AHU?

# data[].attributes.body
You are required to design a 5000m ²  2-storey office, 3 units of male toilets and 3 units of women's toilets sized 100m ² on each floor, two units of 700m ² meeting room or seminar on the ground floor, 350m ² lobby and lounge area. The client wanted to use a centralized air conditioning system inside the building. By using the table 1.1 and Table 1.5  in the lecture note:

1.    Calculate the size of the make-up tank needed for the building

2.    Calculate the size and location of the AHU room required on each floor

3.    Sketch the proposed 2 storey office plans and sectional drawing of the 2-storey office building to show the location of the cooling tower, the make-up tank and the required clearance space according to JKR requirement.

- provide proper airflow and prevent air from entering house or ducting system from polluted zone
-it balance airflow and return the airflow to maintain a neutral pressure in the space.
-minimizes duct air temperature losses between air handler and supply register
- it is properly sized so the static pressure is within manufacture specification.
