REPLACEMENT OF THE EXISTING HVAC PLANT!!!
REPLACEMENT OF THE EXISTING HVAC PLANT!!!
(OP)
Hi Everybody!
I am working on a Offshore & onshore project wherein we need to replace the existing Hvac system with improved Equipment reliability & performance to provide reliable operation..
97 Hvac units(2000 Tons) were serving Substations (2 are onshore), Satellite Instrument house, Analyser room & CCR since 25 yrs..
My question is not how to replace the plant but I am more bothered about the Alternative cooling system...
Before commencing demolition activities the respective buildings shall be provided with stand alone Alternative Cooling by construction contractor for a cooling load equal to the existing capacity to prevent the sensitive electrical and
instrument panels housed inside the buildings from getting damaged.
Proposed Hvac Units & its capacity:
1. Ducted Split A/C - 30T (2Nos)
2. Ducted Split A/C - 9T (4Nos)
3. Ducted Split A/C - 47T (4Nos)
4. Ducted Split A/C - 16T (15Nos)
5. Ducted Split A/C - 14T (3Nos)
6. Ducted Split A/C - 22T (2Nos)
7. Ducted Split A/C - 24T (19Nos)
8. Air Cooled
Chillers - 102T (3Nos)
9. Wall mounted
Package A/C - 5T (14Nos)
10. Bottom Discharge
Package A/C - 8T (14Nos)
(Nominal capacity= 12T)
11. Package A/C - 12.5T (2Nos)
(Nominal capacity= 18T)
Please reflect your experience on this.......

please help me regarding Alternative cooling...
Thanks....
RE: REPLACEMENT OF THE EXISTING HVAC PLANT!!!
If it is a ductless split, you can probably change out the whole thing in less than a day, so the staging of new and old plant is not so important.
RE: REPLACEMENT OF THE EXISTING HVAC PLANT!!!
Ductable split A/cs are used in this project.....
i think as you said for sensitive areas we need to provide spot coolers before decommissioning....
As i am a beginner in this field i dont know much about spot coolers or similar equipments. I would appreciate if you share your knowledge about such kind of equipments...Thanx again!
