Dear All,
We have a projects designed for commercial purpose with 3 main spaces types:
- Restaurant: ~34,000 s.ft., 10 stories
- Offices: ~40,000 s.ft., 9 stories
- Retail: ~12,000 s.ft., 2 stories
The whole building consist of more than 5 floors and does not provide heating in the proposed design, therefore it is determined that System 8 shall be adopted as the baseline HVAC system. According to the building peak cooling load (>300 ton), 2 water cooled chillers with equal size shall be provided in baseline model.
However, we found that the peak thermal load of those 3 spaces differ by more than 31.2 W/m2 from each of them, i.e. Restaurant: ~350 W/m2, Retail: ~215 W/m2, and Office: ~175 W/m2.
In such a case, I should set Office spaces as System 8 (due to its area), then set Restaurant and Retail as System 4?
If so, I should determine the water side again by the peak thermal load of Office spaces ? i.e. If the load of Office spaces is below 300 ton, only 1 water-cooled chiller shall be provided?
Grateful if someone could confirm by interpretation. Thanks a lot!
