Latest company case about Beijing Holtop Artificial Environment Technology Co., Ltd Certifications

• Client: Jinan Yaoqiang International Airport
• Location: Jinan, China
• Project Type: Airport Terminal Expansion/Retrofit
• Solution Provider: Beijing Holtop Air Conditioning Co., Ltd. (Holtop)

​

   In August 2025, Holtop was selected to provide advanced HVAC solutions for the expansion of Jinan Yaoqiang International Airport, a key aviation hub in Eastern China. The project involved the design and delivery of 28 sets of custom-built Pre-Cooling Condensation Dehumidification Fresh Air Units, tailored to address the unique humidity control and energy efficiency challenges of large-scale airport terminals. These systems ensure optimal indoor air quality (IAQ) while significantly reducing operational energy consumption.

Challenges & Requirements

1. High Humidity Load: Large passenger traffic, frequent door openings, and outdoor air infiltration created substantial latent loads.
2. Energy Efficiency Goals: The airport sought to reduce HVAC energy costs while maintaining strict environmental conditions.
3. Space Constraints: Compact yet high-capacity units were required to fit limited mechanical rooms.
4. 24/7 Operation: Systems needed to operate reliably with minimal maintenance disruptions.

Holtop Solution

   Holtop delivered a customized solution featuring Pre-Cooling Condensation Dehumidification Fresh Air Units with the following specifications:

1. Quantity: 28 units
2. Capacity: 10,000–15,000 m³/h per unit (tailored to zone-specific requirements)
3. Pre-Cooling Coil Technology: Pre-cools incoming outdoor air using recovered energy from exhaust air, reducing mechanical cooling load.
4. Condensation Dehumidification: Actively removes moisture before air enters the main HVAC system, ensuring precise humidity control.
5. Energy Recovery Integration: Rotary enthalpy wheels recover sensible and latent energy, reducing overall energy consumption by ~40%.
6. Corrosion-Resistant Construction: Stainless steel components and epoxy-coated casings withstand harsh outdoor air conditions.
