System Working Principle

2. Introduction of Intelligent Ventilation System

2.1 Working Principle

The system is an intelligent ventilation system providing air circulation, air filtration and cooling control for telecom room. The system itself doesn’t include any cooling element. It directly draws cold air into the telecom room from outside and exhaust hot air from telecom room to the outside to realize natural cooling. The system can be used standalone or integrated with air conditioner cooling device.

2.2 Technical Parameters and Application

• Power Supply: DC48V;
• Current: 1A;
• Air Volume: 560CFM;
• Noise: ≤55dB;
• Application: applicable for various types of cabinets.
