For most of HVAC history, specifying heat recovery on a ventilation system was a voluntary energy-saving measure—a nice-to-have that justified itself on payback. That era is over. Today energy codes in the United States and equivalents worldwide treat air-to-air energy recovery as a mandatory requirement above defined outdoor-air thresholds, and designers who omit it must […]
News, market data and practical briefings on China's heat-exchanger and air-to-air heat-recovery sector — written for international buyers, specifying engineers and HVAC&R professionals. We cover market size, manufacturing clusters, the China Refrigeration Expo (CRH), dual-carbon policy, export dynamics, certifications and how to source with confidence. 26YC is a Shandong-based manufacturer; these articles are independent industry reporting, not a sales pitch.
Where China’s Heat-Recovery Demand Comes From in 2026
China’s recovery-equipment boom is not one market — it is four, pulling different products. Understanding the split helps overseas buyers read a supplier’s catalogue. HVAC & new buildings China’s building-energy rules now require all new urban buildings to meet green-building standards, and large or public buildings are pushing energy-recovery ventilation. In the cold north-east, clean-heating […]
China Heat-Exchanger Exports 2026: Buyer Guide
China is not just the world’s biggest heat-exchanger market — it is its export engine. 2025 exports reached roughly US$8.9 billion, with the trade surplus up about 47% versus 2020. The first half of 2026 ran ~US$6.7 billion, up 15.8% year on year. Where it goes ASEAN — fastest-growing neighbour market for HVAC and industrial plates. Middle […]
Why Chinese Heat Exchangers Cost What They Do in 2026
“Why is it so cheap?” is the first question every overseas buyer asks. Here is an honest teardown for a mid-range plate heat exchanger. Cost structure (per unit) Raw materials 55–60% — aluminium (6061/6063) or copper, stainless plates (304/316), and gaskets (EPDM/NBR). Material cost is the swing factor. Labour & assembly 15–20% — brazing, sealing, […]
CRH 2026: HVAC Expo Takeaways on Recovery
The 37th China Refrigeration Expo (CRH 2026) ran 8–10 April 2026 at the Beijing Capital International Exhibition & Convention Center. With roughly 115,000 m² of halls, 1,041 exhibitors from 30 countries and more than 80,000 professional visitors, it remains the single best window into China’s HVAC&R supply chain. The official theme — “Digital intelligence shapes cooling […]
Plate vs Rotary Wheel: What Chinese Factories Are Shipping in 2026
Walk any Chinese HVAC factory floor in 2026 and you will see two air-to-air recovery technologies dominating the line: the fixed-plate recuperator and the rotary enthalpy wheel. They solve the same problem — recovering energy from exhaust air — with opposite mechanics. Knowing which one a supplier pushes tells you a lot about their target […]
China Rise in Heat-Exchanger Patents
For years “Made in China” meant low-cost copies. In heat exchangers that story is ending. Industry reports put Chinese applicants at roughly 38–41% of global heat-exchanger patent filings in 2025 — behind only the combined EU/US lead on fundamental heat-transfer theory, but ahead on volume. Where the patents are going Microchannel aluminium cores for EV […]
CE, AHRI, Eurovent: Verifying Supplier Claims
“We are certified” is the most repeated — and most abused — phrase in Chinese HVAC exports. Here is how to verify it before you pay. CE marking A bare CE sticker is often a self-declaration (Module A) and proves little. For pressurised plate exchangers, ask whether the supplier complies with the Pressure Equipment Directive […]
なぜデータセンターは廃熱回収に賭けるのか
The Data Center Heat Problem Data centers use a large share of the world’s electricity, and almost all of it ends up as heat. Traditionally that heat is dumped outdoors through cooling towers and chillers. With energy costs climbing, operators are asking a simple question: can that heat be used instead of wasted? Two Main […]
Heat Recovery News 2026
Why Heat Recovery Is Moving to the Top of the Agenda For years, capturing waste heat was treated as a bonus project for when the budget allowed. In 2026 that mindset has changed. Energy prices, carbon costs, and tighter efficiency rules have pushed heat recovery from the optional list to the core strategy list for […]
