[AC] 問﹕街市/超級市場空調系統設計上有啲乜要考慮？

答﹕

Design Considerations:

- 大型冷藏櫃 Refrigerated Display Case, Large Sensible Load source，開櫃門的話又係一個大冷源；

- 大量人流，開住大門Outdoor Air Intake，Latent Load Source

Design Strategies:

- Design MVAC system 嗰陣要考慮Refrigerated Display Case factor, AC system sensor location;

- 可考慮reclaim waste heat from Refrigerated Display Case, 但香港似乎不太適用

- Slight possitive pressure to eliminate infiltration of unconditioned outdoor air;

- Air Curtain to create air barrier


- Dehumidification, cost effecitive humidity control in the HVAC system
Condensation or Desiccant Dehumidifiers
