- China's fresh-air (ventilation with energy recovery, ERV/HRV) market reached roughly RMB 40-60 billion in 2024, depending on whether installation and accessories are included. Penetration sits around 12%, far below the 40%+ seen in Europe and North America - leaving substantial long-term headroom as health-awareness and building codes tighten.
- Guangdong (Shunde / Foshan) - the largest HVAC and fresh-air cluster, home to both domestic leaders and a dense tier of OEM/ODM suppliers. Zhejiang - appliance and component base feeding fresh-air unit assembly. Beijing and the Bohai Rim - several established fresh-air specialists focused on commercial and high-end residential projects.
- The market remains fragmented: the brand count fell from nearly 500 to an estimated 300-400 as weaker players exited. First-tier names (annual sales above RMB 100 million) include both international brands and large domestic appliance makers; a second tier covers specialised fresh-air and heat-recovery brands; a long tail of small regional makers competes on price.
- The national standard GB/T 34012-2017 sets technical requirements for fresh-air systems. Two demand drivers stand out: urban air-quality awareness (PM2.5) and post-pandemic focus on indoor air. Smart, IoT-enabled units that modulate flow by CO2, PM2.5 and TVOC are the fastest-growing segment. Note that fresh-air units with recovery cores are, fundamentally, air-to-air heat exchangers - the same plate, enthalpy-wheel and heat-pipe technologies covered throughout this Encyclopedia.
- Volumes dipped about 7-8% in 2024 under weak consumer spending, but industry estimates point to a return to growth from 2027 as green-building and comfort demand recover. Consolidation is raising quality and pushing recovery-core efficiency upward.
