The main part of the intelligent free cooling system is composed of main control box, fresh air system and network management center which includes air supply and air exhaust fans, indoor & outdoor temperature sensor, automatic valve, air filter, AC transformer, outdoor rain cover and intelligent controller. This system brings the outdoor fresh air to cool the communication base station and equipment room based on the temperature difference between indoor and outdoor temperature. It can also exhaust the hot air of the base station and the equipment room to replace the air cooling unit under most conditions in the entire year and avoid the electrical energy waste when the air conditioner is running for a long time which effectively decreases the running time of the air conditioner in communication equipment room to reach the goal of electrical energy-saving.
