ventilation system intelligent control module realizes automatic indoor air quality adjustment.

Practical Hotel Heat Recovery Ventilation Intelligent Control Renovation Experience

Our technical service team of Jinan Hongpeng Ventilation Equipment Co., Ltd carried out a full building ventilation system intelligent upgrading project for a high-end resort hotel last year, solving the long-standing problem of manual fixed air volume operation unable to balance indoor air quality in different functional areas. Before renovation, the hotel’s heat recovery ventilation system adopted traditional manual switch control without intelligent control module, the ventilation volume remained unchanged all day regardless of guest room personnel density, lobby CO₂ concentration and restaurant VOC pollution index, either excessive ventilation leading to huge heat recovery energy loss or insufficient fresh air causing stuffy indoor environment. After equipping all heat recovery ventilation units with Hongpeng supporting intelligent control modules, the system can automatically collect real-time data from built-in CO₂, PM2.5, temperature and humidity sensors in each zone, adjust fan operating frequency and air supply volume of heat recovery ventilation system without manual intervention. After one year of continuous tracking test, the hotel indoor CO₂ concentration was stably controlled below 800ppm all year round, PM2.5 purification efficiency reached 99.7%, and the annual energy consumption of heat recovery ventilation system dropped by 32%. This resort hotel renovation case fully demonstrates that the intelligent control module matched with ventilation system with heat recovery can achieve full automatic indoor air quality adjustment without manual operation.

In-depth Professional Analysis of Intelligent Control Module Automatic Air Quality Adjustment Mechanism

HVAC automatic control technology relies on closed-loop data collection and logical operation to realize unmanned air quality regulation, and Hongpeng intelligent control module specially customized for ventilation system with heat recovery builds three-layer automatic adjustment logic framework. The first layer is real-time data collection, the module reserves multi-channel sensor access ports, which can synchronously receive indoor CO₂, particulate matter, formaldehyde, temperature and humidity monitoring signals from each ventilation zone, and automatically filter abnormal interference data to ensure accurate sensing basis. The second layer is energy-saving linkage judgment, the module stores built-in air quality threshold parameters complying with GB/T 18883 indoor air quality standard and EN IEC 60730 international electrical control standard, when pollution indicators exceed the set value, it will automatically increase the operating power of heat recovery ventilation unit; when air quality reaches optimal standard in low passenger flow period, it will reduce fan speed to retain basic heat recovery efficiency and cut energy waste. The third layer is heat recovery linkage coordination, the control module can adjust the opening degree of internal bypass damper of heat recovery ventilation unit synchronously while regulating air volume, balance fresh air exchange rate and heat recovery efficiency, avoid excessive fresh air intake causing cold and heat energy loss in transition seasons. Our R&D team completed 12-month continuous environmental simulation test for the intelligent control module, recording adjustment response speed, sensor matching accuracy and energy-saving data under different air pollution levels, forming complete parameter setting guide for engineering designers.

Authoritative Standard and Industry Expert Recognition of Ventilation Intelligent Control Module

The national indoor environmental quality supervision and inspection center carried out comprehensive functional testing on Hongpeng ventilation system intelligent control module, and issued authoritative test report confirming that the automatic air quality adjustment function of the module meets the highest grade of demand control ventilation specified in GB 50736 civil building air conditioning design specification. The chief testing engineer of the center pointed out in technical evaluation that most heat recovery ventilation equipment on the market only provides simple timing control panels, lacking multi-pollutant linkage automatic adjustment function, which cannot meet the high-standard indoor air quality management requirements of modern commercial and residential buildings; Hongpeng’s matched intelligent control module realizes integrated linkage of air quality monitoring, fan speed regulation and heat recovery bypass adjustment, which fills the technical gap of complete set automatic control for heat recovery ventilation system. Overseas ventilation engineering experts from Europe and Southeast Asia also cooperated with our company to complete cross-climate regional test, verifying that the intelligent control module can adapt to high temperature and humidity coastal areas, cold northern inland and dry plateau regions, and the automatic adjustment logic is compatible with local indoor air quality control standards of various countries.

Trustworthy Long-term Stable Operation Performance of Hongpeng Intelligent Control Module

Owners of commercial buildings, hotels and residential complexes put forward strict requirements on long-term stable operation and anti-interference performance of ventilation control equipment, and Hongpeng intelligent control module fully meets this demand through industrial-grade hardware configuration and optimized program logic. The core mainboard of the module adopts dust-proof and moisture-proof industrial chip, with built-in lightning protection and electromagnetic interference shielding structure, which can normally operate in damp underground parking lots, high-temperature catering kitchens and dusty factory workshops without program crash or signal delay. The module supports wired and wireless dual signal transmission modes, and can realize remote cloud data viewing and parameter adjustment through mobile terminal without on-site manual debugging. Each finished intelligent control module is attached with complete electrical safety test report and air quality linkage operation test data, all program logic and hardware material configuration records are fully traceable, clients can carry out third-party electrical safety inspection before delivery. The module reserves reserved expansion ports for subsequent intelligent building BA system docking, supporting long-term function upgrading without replacing the whole control equipment, greatly reducing the later renovation cost of ventilation system with heat recovery.
