Overcoming Air Treatment Hurdles in Airport Terminals
Airport terminals, characterized by their vast spaces and high - density passenger flow, pose formidable challenges in air treatment. The complex air circulation within these areas demands stringent control over temperature, humidity, high - level air cleanliness, and energy - efficient operation. Maintaining a consistent and comfortable indoor environment for passengers throughout the day is no easy feat.
Traditional air - conditioning systems often fall short in such demanding scenarios. Issues such as uneven temperature and humidity distribution, a propensity for condensation, exorbitant energy consumption, and operational instability are common. These limitations make them ill - equipped to meet the long - term, high - load operational requirements of airport terminals. For instance, in large - scale airport halls, traditional systems may struggle to ensure that every corner has the same comfortable temperature and humidity level, leading to discomfort for passengers.
In the case of Jinan Yaoqiang International Airport's terminal, there was an urgent need for an air - conditioning system that could maintain high - precision temperature and humidity control while operating with low energy consumption under year - round high - load conditions. This is where HOLTOP's innovative air - handling solutions come into play, offering a much - needed alternative to the shortcomings of traditional systems.
HOLTOP's Advanced Air Treatment Solutions
1. Temperature and Humidity Independent Control (THIC)
HOLTOP's solution features the Temperature and Humidity Independent Control (THIC) system, a cutting - edge technology in the field of high - efficiency energy - saving air - conditioning. This system operates on the principle of completely separating temperature and humidity control. The sensible heat terminals are responsible for temperature regulation, while the condensing dehumidification fresh air units handle humidity control. This separation fundamentally addresses the energy waste and control instability issues caused by the "thermal - humidity coupling" in traditional central air - conditioning systems.
HOLTOP's pre - cooled condensing dehumidification fresh air unit adopts a dual - cold - source dehumidification structure design. This design enables deep dehumidification and precise control of the moisture content. Paired with radiant terminals and sensible heat terminals, it achieves accurate temperature and humidity adjustment, realizing the concept of "separate temperature and humidity control, and energy supply on demand". Compared with traditional air - conditioners, the utilization rate of the cold source is increased by approximately 50%, and the system energy consumption is reduced by more than 25%. This not only ensures a comfortable indoor environment but also significantly contributes to energy conservation in large - scale public buildings like airport terminals.
2. Radiation - based Air Supply
In the air - conditioning system of Jinan Yaoqiang International Airport's terminal, radiation terminals play a crucial role in temperature control. These terminals use water as a refrigerant and transfer heat through ceiling or floor coils. The heat transfer mode is mainly radiation, supplemented by convection. This unique heat - transfer method significantly improves the uniformity of the indoor temperature field. Passengers in the terminal will not experience the discomfort of direct cold air blowing, and the noise interference is minimized, creating a quiet, gentle, and comfortable waiting environment.
The system's use of high - temperature chilled water leads to high - efficiency cold - source operation. Compared with traditional systems, it can save 10% - 25% of energy. This energy - saving advantage, combined with the enhanced comfort, demonstrates the superiority of the radiation - based air - supply system in large - space environments. HOLTOP's coordinated design of the temperature and humidity independent control system enables deep interaction between the pre - cooled condensing dehumidification fresh air unit and the sensible heat terminals. Multiple - point temperature and humidity sensors are deployed in key areas to monitor the dew point in real - time. The system dynamically adjusts the water - supply temperature and the moisture content of the supply air. Through intelligent coordinated control logic, it strictly prevents ground condensation, solving a major problem in the implementation of radiant cooling in large - scale public buildings.
3. High - Efficiency Energy - Saving Technologies
To address the high - energy - consumption pain point of large - scale air - conditioning systems, HOLTOP incorporates a variety of energy - saving technologies and components into its units. A plate - fin heat exchanger is installed inside the unit to recover the energy contained in the exhaust air. With its compact heat - exchange structure, it can fully recover the exhaust air energy, achieving a heat - recovery efficiency of over 70%.
In the dehumidification module, the unit makes full use of the condensing waste heat through the condensing re - heat technology. Equipped with a high - precision expansion valve for fine - tuning, it can achieve stepless output of re - heat energy, accurately matching the heat demand and avoiding energy waste while reducing additional heating energy consumption.
The unit is also equipped with energy - saving EC fans. These fans are designed using AMCA - certified professional software, and their parameters are precisely calculated and matched to the unit to ensure efficient output. The fan speed can be steplessly adjusted to accurately adapt to the air - volume requirements under different passenger flow conditions. The application of these energy - saving technologies and components significantly reduces the system's operating energy consumption, improves energy - use efficiency, and saves long - term operating costs, making it highly suitable for the energy - saving needs of energy - intensive scenarios like airport terminals.
4. Comfort - oriented Design
HOLTOP's air - conditioning equipment is filled with human - centered design details. The unit is equipped with a natural water - soaked stone wet - film humidifier. Relying on the porous structure of the material, it absorbs water and then naturally evaporates to complete the humidification process. This humidification method is safe, natural, and energy - efficient. Its automatic humidity - adjustment feature and good adsorption performance are especially friendly to the elderly, children, and people with respiratory sensitivities.
In the design of the unit function sections, HOLTOP always takes the user's perspective into account.
