In order to save, most mobile base stations are unattended, but the various electronic devices in these communication base stations need to be in a certain temperature environment (base station environment national standard GB50174-93 stipulates that the temperature of the base station for long years is 18 ℃ ～ 28 ℃) in order to run normally for a long time. In order to reach the standard ambient temperature of the base station, each communication base station is equipped with about two air conditioners, and these air conditioners are turned on for many years. The current status is:
a. Increase in base station electricity bills According to statistics from a regional mobile communications branch, the electricity bills for 138 base stations in 2006 were RMB 2.12 million, and the electricity bills for 238 base stations in 2006 exceeded RMB 5.8 million. Electricity expenses increased by 58%.
b. The base station air-conditioning electricity costs account for a large proportion According to statistical analysis of the data, the average electricity cost of each base station air-conditioning accounted for about 54% of the entire base station electricity cost, air-conditioning has become the main power equipment in base stations.
c. The waste of electricity in base station air conditioners is more serious. At present, most base station air conditioners are set to cool at 18 ° C or automatically at 24 ° C. Since the base stations are unattended, many base station air conditioners are turned on throughout the year and the waste phenomenon is more serious.
• According to the relevant national regulations on the operation of electronic equipment, the general base station temperature should be maintained at 18 ℃ ~ 28 ℃, humidity 10%-90%, if the base station air conditioner is used in conjunction with the safety and energy saving ventilation system produced by our company There is a lot of room for energy saving.
The power consumption of the air conditioner is a huge expense for the communication operating company. In most areas of China, the natural room temperature in many time periods can meet the temperature requirements for the normal operation of electronic equipment, or only one air conditioner can work intermittently to meet the temperature requirements for the normal operation of these electronic equipment.
Based on the above reasons, we have adopted international advanced control theory and technology, based on the international base station general standards and the long-term test report data of the best environment for reliable and safe operation of electrical equipment, we have developed and designed a base station ventilation energy-saving system. At the same time, it also has a reliable security alarm function and a perfect networking function.
The principle of the system is that the temperature rise in the base station is caused by the long-term running heat of electrical equipment, not the ambient temperature outside the station. If air conditioners are used throughout the year to maintain the temperature inside the station (mainly cooling), the favorable conditions for the outdoor low temperature in the winter, spring, autumn and summer periods in the morning and evening periods can be dissipated and cooled, which leads to the waste of electric power and operating costs. High.
The base station ventilation energy-saving system makes full use of the temperature difference between the indoor and outdoor base stations to form a heat exchange, and relies on a large amount of air circulation to effectively move the heat inside the base station outward quickly to achieve indoor heat dissipation. Thereby greatly reducing power consumption and operating costs, extending the service life of air conditioners.
The base station ventilation energy-saving system can work independently, or can be connected to the power monitoring module through RS232 or RS485 bus, and upload data to the monitoring center through different transmission networks. This system is mainly to improve the operation efficiency of air conditioning and use automatic ventilation The principle of temperature regulation, so as to save energy, in order to achieve the purpose of reducing operating costs.
Base station energy-saving ventilation system
The era of base station energy-saving ventilation system information has arrived. The human society's demand for communication is increasing. The communication service provider (SP / ISP) expands the investment of the network and increases the coverage of the network, so as to reach any time, any place, and The effect of anyone's communication. The number of mobile base stations, access websites, and modular offices of operating companies is increasing, especially the number of mobile base stations is increasing very rapidly.
