01 Background
A fresh-air project focused on quiet, comfortable guest rooms. Silent cabinets with double-layer sound insulation and water-cooled fresh air units form the fresh-air system, replacing stale air and removing odor. A small backward-curved cabinet handles the hotel light-dining area. The gentle, stable airflow, full vibration isolation and low noise meet the high standards of a light-luxury hotel.
Ventilation equipment zoned for guest rooms, lobbies and dining areas with fresh air, quiet and exhaust needs.

02 On-Site Problems
Closed guest rooms with poor airflow, stuffiness and odor; common areas and dining zones needing zoned ventilation; and high noise requirements.
03 Equipment Used

Low-noise operation for quiet guest rooms.

Delivers cooled, clean fresh air.

Extracts dining-area fume to prevent odor spread.

04 Our Solution
Guest rooms focus on quiet fresh air and dining areas on fume extraction, running independently around the clock.
05 Installation Process
Silent cabinets are placed in plant rooms or ceilings, fresh-air units distribute air to rooms, and dining-area cabinets connect to hoods and ducts, all vibration-isolated with zoned ducting to fit existing hotel services.
06 Results
Continuous fresh air in rooms, less odor, better common-area circulation, smooth dining exhaust, and quiet operation that protects guest rest for an improved stay.
