HVAC TESTING AND BALANCING AIR & WATER SYSTEM

HVAC Testing and Balancing Air & Water System

The systematic approach, basically applicable, to all systems is, as per following steps:
(More specific details will be provided upon submittal requests and actions)

1. The preliminary office works, will include i.e. 

a)  Gather  plans  and  specifications,

b)   Prepare report forms,

c)   Study  the plans and spec,

d)   Label all pieces of equipment, number all terminal devices, circle on the air side: volume dampers, automatic dampers, fire dampers etc. circle on the waterside: all balancing valves, flow meters, automatic control valves, etc.

e)  Determine  the method of balancing,

f)   Schematic  drawing of each system,

g)  Detail the central system with pressure and temperature drops across components, duct and pipe sizes, terminal devices, balancing valves and dampers, actual flow quantities, etc

2. The preliminary site inspection, will include i.e.

a)  Inspect the job site to ensure that the building is architecturally ready,

b) Inspect the distribution system, and walk the air and water distribution systems to ensure that they are intact, and aren’t missing components such as:

• Dampers,
• Valves
• Pressure and temperature taps
• Coils
• Terminal boxes
• Diffusers
• Grilles
• Etc.

 (Commissioning codes of practices .CIBSE Commissioning Code A + CIBSE Commissioning Code W.)

c) Inspect the equipment i.e.  check motors, fans,, pumps, chillers, compressors, boilers, drives, etc.,  to ensure that all  

 are mechanically and electrically ready.

            
The equipment items to be checked:


a)   Air Side, to ensure that :


•    Ductwork intact and properly sealed
•    Ductwork leak tested.
•    Access doors installed and properly secured
•    Ductwork installed according to the drawings and specification.
•    Ductwork free from debris
•    Dampers, including fire and smoke dampers, installed and accessible.
•    Terminal boxes, reheat coils, electrical reheat, etc., installed, functional and accessible.
•    All other air distribution devices such as diffusers, etc., installed and functional.
•    Return air has an unobstructed path from each conditioned space back to the unit.
•    Filters clean and correctly installed.
•    Filter frame properly installed and sealed.
•    Coils cleaned and properly installed.
•    Drive components installed.
•    Sheaves properly aligned and tight on their shafts.
•    Belts adjusted for the correct tension.
•    Belt guard properly installed.
•    Automatic control dampers installed and functional.
•    Fan vortex dampers functional.
•    Fan housings installed and properly sealed according to the drawings and specifications.
•    Flexible connections installed properly.
•    Fan wheel aligned properly and adequate in the housing.
•    Fan bearings lubricated.


b)   Water side, to ensure that :


•    Strainers and piping free from debris cleaned and flushed.
•    Construction strainer baskets replaced with permanent baskets.
•    System filled to the proper level;and the pressure-reducing valve set.
•    Automatic and manual air vents properly installed and functional.
•    All air purged from the system.
•    Water in the expansion tanks at the proper level.
•    All valves, flow meters, and temperature/pressure taps installed correctly, accessible and functional.
•    Terminal coils installed and piped correctly and accessible.
•    Pumps properly aligned, grouted and anchored.
•    Vibration isolators properly installed and adjusted.
•    Flexible connections installed properly.


c)   Boiler ( in accordance with Commissioning codes of practices: CIBSE Commissioning Code B),to ensure that :


•    All operating and safety settings for temperature and pressure are correct.
•    Pressure relief valve functional.
•    Boiler started and operating properly.

d)  Chiller and Condenser , to ensure that


•    All operating safety settings for temperature and pressure are correct.
•    Chiller and condenser started and operating correctly.

e)  Electrical, to ensure that :


•    Motors wired and energized.
•    Proper starter and overload protection installed.
•    Correct fuses installed.
•    Motors properly secured on their frames.
•    Motor bearings lubricated.

f)   Control, to ensure that :

      Controls are complete and functional.


3. Initial tests on all fans and pumps applicable to the system being balanced.

4. Balance and adjust the distribution system.

5. Adjust the fans or pumps as needed.

6. Take final readings.

7. Complete reports
