Shenzhen Telecom Scientific & Technology Co., Ltd is the manufacturer of Intelligent Ventilation System for Communication Enclosures.
.
A. Principle of the system
According to the different temperatures between outside & inside the Communication Enclosures, the system input the clean & cooling air to cool the room, while the heat will be discharged. The system gets the effect of refrigeration instead of air conditioners. It is designed to remove excess heat from temperature sensitive electronic equipment where the temperature is required to be maintained within defined limits to achieve optimum performance and to maximize component life.
B. Composition of the system
The ventilation system is mainly made up of control unit, air intake device, air exhaust unit, indoor and outdoor temperature sensors, indoor and outdoor humidity sensors, outdoor dust sensor, covers, dust filters and other installation accessories.
C. System Work Processes
First of all, we set the parameters of the system through the buttons of the control unit. The system real-time detects the indoor and outdoor temperature, humidity and dust degrees. Through rational calculation of logic programming, the system can automatically control the running or closing of the ventilation system and air conditioners and then achieve the best energy saving results.
The ventilation system not only can work independently, but also can upload the data to the monitoring center through the RS485 or GPRS wireless module to achieve the remote management and controlling.
D. The main features of the system
1. The host chip and all devices are industrial devices and can maintain a long run.
2. Remarkable energy savings: the system can save 30%-60% energy consumption, with significant economic benefits.
3. Perfect dust-proof effect.
4. No damage to the wall of the base station, security.
5. Support the remote network management and the operating status of the terminal can be known in the NMC.
6. The ventilation system operates under the linkage with the air-conditioning and maximize energy-saving..
7. LCD screen display, easy to operate. The parameters can be set..
8. 4-way alarm input.
9. Support the malfunction alarm, including the malfunction of the sensors, fans and air-conditioners.
10. with the alarm function of ultra-low temperature and ultra-high-temperature.
11. The loop of the controlled parts can be detected.
12. Controller cans automatically storages the environmental parameters and running status of the fans, air-conditionings which collected.
