Rapid regulatory change is pushing industrial HVAC toward low‑GWP refrigerants and higher‑efficiency air systems. In the EU, the 2024 F‑gas Regulation accelerates the phase‑down and introduces stricter equipment rules, prompting widespread adoption of next‑generation refrigerants such as R‑32, R‑454B, and R‑1234ze in VRF, packaged rooftops, and process chillers. Safety engineering for mildly flammable A2L gases—gas detection, ventilation safeguards, and charge management—is becoming routine in design submittals and commissioning plans.
Simultaneously, the airside is being re‑architected around energy‑recovery ventilation and dedicated outdoor air systems (ERV/DOAS). Sensible/latent wheels or run‑around coils recover exhaust energy, while EC fans selected by FEI deliver required flow at lower power. Pairing ERV/DOAS with zoning and smart controls cuts ventilation loads, stabilizes humidity for product quality, and protects indoor air quality (IAQ).
For owners, the mix of compliant refrigerants and FEI‑optimized air handlers lowers electrical demand and operating cost while safeguarding future availability as supply chains shift. When combined with continuous commissioning and metered KPIs—kWh/ton, ventilation effectiveness, and space dew point—plants meet tightening codes and ESG targets without compromising safety or comfort.
