cleanroom differs from a normal comfort air conditioned space, in the following ways. 1. Increased Air Supply: Whereas comfort air conditioning would require about 2-10 air changes/hr, a typical cleanroom would typically require 20 - 60 air changes and could be as high as 600 for absolute cleanliness. The large air supply is mainly provided to buildings, etc. Depending of the air flow, they could be separated in nine standard sizes from 6000 m³/h to 45000 m³/h. • Modifications depending on the installations of air handling units: • AHU–H - horizontal version (air handling unit with mixing and intermediate coolant) – (AHU 06 – AHU 45H)
Also, the design of the building must comply with the Owner’s Project Requirements document that has been provided. For this competition the owner has decided that he wants to use a variable air volume (VAV) air handling unit (AHU) for the building. Thus, the HVAC System must use a VAV air handling unit for all the spaces.
