Project Introduction
Hong Kong commercial buildings often face high-density occupancy and problems of stuffiness and humidity. In addition to improving indoor air quality, the fresh-air system adopts an advanced HVAC system that uses a complete treatment process of “high-efficiency heat recovery + pre-cooling + deep dehumidification”. Filtered and deeply purified clean fresh air is steadily supplied into the interior, establishing a comfortable low-temperature and low-humidity foundational environment.
The system continuously supplies highly filtered and treated fresh air. It not only effectively controls and removes major indoor pollutants, but also significantly reduces odours and bacterial growth, thereby greatly enhancing the freshness and cleanliness of indoor air. This creates a healthy, odour-free office environment with low pollutant concentrations for employees, fundamentally improving the health risks and comfort issues caused by long-term poor indoor air quality.
Key Results
Advanced heat-exchange technology promotes efficient circulation of indoor and outdoor air, avoiding feelings of stuffiness and confinement. Stable fresh-air supply is maintained during peak periods, improving air circulation by more than 40% and creating a comfortable and pleasant office atmosphere.
Pre-cooling technology further ensures the indoor environment remains cool without feeling muggy, and reduces the original air-conditioning load. Through the above comprehensive optimisations, the system’s overall energy consumption is reduced by approximately 30%, with an investment payback period of only about 3 years. This achieves both healthy comfort and significant energy-saving economic returns.
