In pharmaceutical, electronics manufacturing, and high-end laboratory settings, the goals of HVAC systems extend far beyond comfort — they involve a comprehensive balance of air cleanliness classification, pressure differential control, energy consumption, and process stability. This gives HVAC simulation a strong industry-specific focus.

Industry Characteristics

  • Airflow distribution directly affects cleanliness and contamination risk
  • Pressure differentials and air change rates require stable control
  • High O&M energy consumption with significant room for system optimization

Typical Simulation Tasks

  1. Supply/return air distribution and dead zone identification
  2. Cleanroom pressure cascade and contaminant propagation assessment
  3. Impact of equipment heat dissipation on localized temperature and humidity
  4. Airflow and energy consumption comparison before and after energy-saving retrofits

Recommended Solution

It is recommended to use room-level CFD as the core, combined with system-level airflow and control strategy verification. For high-grade clean zones, attention should also be paid to transient effects caused by personnel activity, door-opening disturbances, and equipment heat generation — rather than relying solely on steady-state results.

Practical Value

A mature HVAC simulation solution can simultaneously support validation and retrofit decisions, helping building owners meet cleanliness requirements while minimizing long-term operating costs.
