HOLTOP leverages its leading energy-efficient air handling technology and extensive experience in large spaces public building projects to help Jinan City, Shandong Province, build a comfortable, intelligent, low-carbon, and energy-efficient international airport.
The Phase II expansion of Yaoqiang International Airport represents the largest civil aviation construction project in Shandong's history and a pivotal initiative to establish Jinan as an international integrated transportation hub. Positioned as a “world-class, domestically leading”modern transportation nexus, the completed airport will form a comprehensive aviation hub seamlessly connecting air, rail, tram, and road transportation.
The airport terminal features expansive spaces with high passenger density and complex airflow patterns, demanding stringent requirements for temperature and humidity control, cleanliness, and energy efficiency. To meet the HVAC demands of such large space environments, HOLTOP provides a comprehensive HVAC solution capable of maintaining high-precision temperature and humidity control with low energy consumption even under year-round high-load operation.
Dual Control of Temperature and Humidity
The terminal building at Yaoqiang Airport employs a Temperature and Humidity Independent Control (THIC) system. This system completely separates temperature and humidity control functions, assigning thermal terminals and condensing dehumidification fresh air units to regulate temperature and humidity respectively. This fundamentally resolves the energy waste and unstable control issues caused by traditional centralized air conditioning systems.
The HOLTOP HVAC solution achieves deep dehumidification and precise moisture content control. Combined with radiant and sensible heat terminals for accurate temperature and humidity regulation, it enables “separate temperature and humidity control with demand-based energy supply”. Compared to traditional systems, this approach increases cooling source utilization by approximately 50% and reduces system energy consumption by over 25%.
Radiant Supply Air
In the terminal building's HVAC system, radiant terminals primarily control terminal temperature. Utilizing water as the refrigerant, the system transfers heat through ceiling or floor coils, relying mainly on radiant heat transfer with convection as a supplement. This significantly improves spatial temperature uniformity, avoids direct cold airflow and noise interference, and creates a quiet, gentle, and comfortable environment. The system utilizes high-temperature chilled water, achieving high cooling efficiency and delivering 10%-25% greater energy savings compared to traditional systems. This approach successfully balances quiet comfort with energy efficiency in large space environments.
Through coordinated design of independent temperature and humidity control systems, HOLTOP achieves deep integration between pre-cooled condensing dehumidification fresh air units and sensible-heat terminals. Multiple temperature and humidity sensors deployed in critical zones monitor dew points in real time, dynamically adjusting supply water temperature and air humidity content. Intelligent collaborative control logic strictly prevents floor condensation. During construction, modular zoning and precision piping techniques ensure safe, stable, and efficient system operation, overcoming implementation challenges of radiant cooling in large public buildings.
High Efficiency & Energy Savings
Addressing the high energy consumption of large space HVAC systems, HOLTOP integrates multiple patented technologies and energy-saving components into AHUs. Internal plate-fin heat exchangers recover energy from exhaust air,their compact design maximizes energy recovery with over 70% efficiency. Within the dehumidification units, condenser reheat technology fully recycles waste heat from condensation. Combined with high-precision expansion valves for fine-tuning, this enables stepless reheat output. It precisely matches heat demand to eliminate waste while reducing supplementary heating energy consumption. The units incorporate energy-efficient EC fans, utilizing AMCA-certified professional software to precisely calculate and match unit parameters,this ensures high-efficiency fan output and accurate adaptation to airflow demands across varying occupancy levels.
The application of these energy-saving technologies and components significantly reduces system operating energy consumption. This not only enhances energy utilization efficiency but also delivers long-term operational cost savings, meeting the energy-saving requirements of high-energy-consumption scenarios like.
Comfort Design
To ensure comfortable of supply air, HOLTOP features natural pumice stone humidifiers. These utilize the material's porous structure to absorb water and achieve humidification through natural evaporation, offering safety, natural operation, and low energy consumption. Its automatic humidity regulation and excellent adsorption properties make particularly suitable for the elderly, children, and individuals with respiratory sensitivities.
HOLTOP's units design achieve a comprehensive balance between comfort for users, practical operational performance, maintenance accessibility, and low energy consumption. Centered on technological innovation, we continuously optimize the product's full lifecycle value.
Intelligent Control
HOLTOP possesses extensive expertise in controlling large space HVAC systems for airport terminals, stadiums, and similar facilities. Its digital intelligent control system, deployed in the control room, collects data from temperature and humidity sensors located beneath seating in waiting areas, at manifold outlets, and in shaded, cold corners without solar radiation. Through comprehensive calculations, it assesses indoor air conditions, applies differentiated control strategies, and automatically adjusts unit operation to precisely meet terminal requirements for air temperature, humidity, freshness, and cleanliness. Additionally, the system features self-diagnostic capabilities that continuously monitor equipment status, promptly alerting and pinpointing anomalies to ensure efficient maintenance and stable operation.
For the Yaoqiang Airport HVAC system, HOLTOP has established a comprehensive service guarantee and full-cycle management system spanning design, equipment manufacturing, installation, and commissioning. This foundation ensures the stable operation of the HVAC system and meets the airport's indoor environmental control requirements, supporting Yaoqiang Airport's efficient, low-carbon operations and offering a new solution for large space HVAC!
