Comparison of Computer Room Air Conditioning (CRAC) and Comfort Air Conditioning: Key Differences and Characteristics
Differences between Precision Air Conditioning (PAC) and Comfort Air Conditioning (CAC):
| Aspect | Precision Air Conditioning (PAC) | Comfort Air Conditioning (CAC) |
|---|---|---|
| Service Target | Machines | People |
| Sensible Heat | High | High latent heat |
| Air Volume | Large | Small |
| Energy Efficiency | Low/Good | High/Poor |
| Size | Large | Small |
| Reliability | High | Low |
| Operating Hours | Long | Short |
| Humidity Control | ±5-10% | ±15-20% |
| Temperature Control | ±1°C | ±3°C |
Machine Room: This refers to rooms housing machine equipment, including computer rooms, electronic equipment rooms, precision processing rooms, data center rooms, and communication rooms.
Characteristics: Mainly serves machinery and equipment. Few personnel, limited air exchange with the outside (low fresh air load), high sensible heat, stringent requirements for temperature and humidity control, and high cleanliness requirements.
Data Center Rooms: Includes server rooms, battery rooms, control rooms, offices, power distribution rooms, air conditioning systems, fire protection systems, and security systems.
Main Functions of Precision Air Conditioning: Heating and humidification, cooling and dehumidification, air filtration.
