SYSTEM / EQUIPMENT DESCRIPTION
The Air Handling unit is designed to provide and maintain the following conditions in the area where it caters
- AHU Capacity of air filtration — 2718 CFM.
- Temperature — NMT 25 ºC
- RH — NMT 60 %
Description:
Air handling unit (AHU-GF-02) is a recirculation system, in double skin modular construction. AHU will have extruded aluminium frame with sandwiched panel of G.I. sheet duly pre coated from outside & 43 mm thick PUF filled in between.
Fresh air enters through 10µ fresh air filter. Air then passes through mixing section with (10 +5) µ pre filter, 6 rows deep CHW coil & 2 rows deep HW coil is placed on condensate tray, Sandwiched type in SS-304 construction with proper drain point. The air will then pass through 3µ fine filter installed in AHU supply plenum.
FA damper are provide with 10µ G-4 pre filter, EA damper are provide with (0.3µ)H-13 HEPA filter.
Filtered air after 3µ filter will be supplied to the room via leak proof GSS Ducting through ceiling mounted Supply air Hepa (0.3 µ) H-13 and air will return through return air Riser via return duct to mixing chamber.
Both ends of the GI ducts will have flanges & flanges will have neoprene gasket. GI ducts will be thermally insulated by Polyethylene foam insulation. Air volume control dampers shall be installed at (fresh, return) air inlet, (supply, bleed) air outlet of AHU and Supply air Hepa & Risers. Fire damper should be installed on supply & return air duct near to AHU.

INSTALLATION VERIFICATION
It was checked and proved that the Air Handling unit and the documentation correspond to the order. In addition, changes and supplements were identified and documented. This review is the basis for further functional reviews, maintenance and modification control.
The IQ protocol defines test procedures, acceptance criteria and the documents that are necessary to prove that the Air Handling unit was installed correctly and corresponds to the specifications of the manufacturers as well as client and that it is suitable for the planned application. The completely executed and finally approved protocol confirms that the Air Handling system is corresponds to all acceptance criteria.
The Installation-Qualification is valid as documented evidence, that the Air Handling Unit corresponds with all checkpoints of design plans, all components of manufacturer’s documentation, rules of technique and the defined requests of M/s. Client, The basis for the installation qualification was the detailed design, room tables and the technical Manufacturers documentation.
The following appendices, in the qualification protocol attached, were used for execution of the installation qualification to prove the Air Handling Unit corresponds with the defined requests of M/s. Client.
The following drawings were compared on site to the existing installation:
Design Verification
The following components were checked if they are according to the design specification:
- Fresh air filter (G-4)
- Pre Filter (G-4 +F-5 ) Combo
- Fine Filter (F-7)
- Bleed Air Filter (H-13)
- Supply Blower – Motor
- Cooling coil
- Heating Coil
- Supply/Return Air dampers
- Fire Dampers
- Duct work
INSTALLATION CHECK
The listed drawings shall be compared on site to the existing installed and any discrepancy shall be marked by redlining in the drawing. After the completion of the walk down, the checked drawings have to be signed with date and signature and have to be attached to these protocols.
