HVAC Project (Industrial) 空调通风工程(工业)

1. Core Objectives

• Temperature Control: Maintain a stable environment for equipment and production.

• Ventilation: Remove hot air, exhaust gases, and dust while supplying fresh air.

• Humidity Control: Maintain required humidity levels for processes (e.g., low humidity for electronics, constant humidity for pharmaceuticals).

• Air Cleanliness: Achieve specific cleanliness standards (e.g., cleanrooms).

• Energy Efficiency & Environmental Compliance: Optimize energy usage and meet environmental regulations.

2. Main System Components

1. Air Conditioning System (Cooling & Heating)

   • Chillers (water-cooled or air-cooled)

   • VRF/VRV systems

   • Terminal units (Fan Coil Units, Air Handling Units – AHU)

2. Ventilation System

   • Supply air systems: Provide fresh air

   • Exhaust systems: Remove waste air and heat

   • Local exhaust systems (e.g., welding fume extraction, oil mist collectors)

   • Heat recovery systems for energy saving

3. Air Treatment Equipment

   • Air Handling Units (AHU)

   • Fresh Air Handling Units (FAHU)

   • Energy Recovery Ventilators (ERV)

   • Dehumidifiers / Humidifiers

4. Ductwork & Piping

   • Air ducts, refrigerant piping, chilled water piping

   • Valves, silencers, insulation materials

5. Control System

   • Building Automation System (BAS/BMS)

   • Temperature, humidity, pressure, and airflow control
