Precision Guardianship for Vintage Treasures: HVAC System for the 170m³ Wine Cellar at Huayue Hotel, Shanghai Exhibition Center
Project Challenge:
Huayue Hotel at the Shanghai Exhibition Center required the construction of a precise and stable environmental control system for its 170 cubic meter premium wine cellar. The cellar demanded exceptionally high stability in temperature and humidity (temperature constant at 12-14°C ±1°C, humidity maintained at 55-75% ±5%), while also necessitating the elimination of potential risks from vibration, odors, and stagnant air that could compromise the wine collection. The client mandated that all equipment be ceiling-mounted and concealed to preserve the cellar's aesthetics and spatial integrity.
Our Solution:
We engineered a "Dual-Redundant" Professional Climatic Control System for the cellar: installing two ceiling-mounted, wine cellar-specific air conditioning units for primary/backup operation and precise temperature/humidity management, complemented by a ceiling-mounted Energy Recovery Ventilator (ERV) with purification to introduce filtered fresh air and exhaust potential trace odors and volatile organic compounds (VOCs). All equipment was seamlessly integrated into the ceiling.
Core Technology Applied:
- Dual-Unit Synergy, Precision Control:The two ceiling-mounted wine cellar AC units operate with intelligent, coordinated control. They automatically adjust their running mode based on real-time load, achieving temperature precision within ±0.5°C and stable humidity regulation, ensuring a consistently flawless environment year-round.
- Dual-Purpose Ventilation with Purification:The ceiling-mounted ERV is equipped with primary and activated carbon filters, effectively purifying incoming outdoor air. Its enthalpy exchange core recovers energy during ventilation, preventing disruption to the cellar's delicate temperature/humidity balance and effectively preventing cross-contamination of odors.
- Silent, Vibration-Free, & Secure Operation: All units incorporate professional anti-vibration design and ultra-low noise fans, ensuring operation is free from disruptive vibrations or noise, providing an absolutely secure storage environment for valuable wines.
Project Outcome:
Since commissioning, the cellar's environmental parameters have met and exceeded specifications, with temperature and humidity graphs showing remarkably stable curves. Hotel management reported: "The system operates with exceptional quietness and stability. We no longer worry about environmental fluctuations. The ventilation system keeps the cellar air consistently fresh and pure." This system not only provides museum-grade preservation for the hotel's fine wine collection but has also become a critical component of its premium service offering, showcasing the hotel's commitment to meticulous detail.
This project successfully demonstrates our robust technical capabilities and reliability in providing comprehensive environmental solutions for high-end wine cellars, art storage, and other specialized spaces.
