6 Frequently Asked Questions about “Electricity charges for telecommunication base stations in China”
Why do telecommunication base stations consume more energy than other public buildings?
1. Introduction Telecommunication base stations (TBSs), which are the basis of the telecommunications network, consume more energy than other public buildings due to their high inner heat density and special operating schedule.
Why is energy conservation important in Guangzhou?
Guangzhou, as one of the fastest developing cities in China, has more than one thousand existing TBSs and the total annual electricity bills are in the tens of millions of RMB, 25% of which is the cost of air conditioning. With the rapid growth of telecommunications, energy conservation for TBSs is gaining greater attention in China.
Can VCT be used in TBS in Guangzhou?
The condensation risk on the interior surfaces of the building envelopes is quite low. The energy conservation achieved by the use of VCT is about 49%, and the payoff period is less than two years. The application of VCT in the TBSs in Guangzhou is feasible, and obvious economic and social benefits will be achieved if VCT can be broadly applied.
Are TBS buildings energy efficient?
TBS buildings have large numbers, high energy consumptions and great potentials on energy conservation. Through field investigation of a typical TBS in Guangzhou, the basic information of TBS was achieved, the key factors influencing energy consumption of TBS were determined and several building energy efficiency designs were proposed.
What is the payoff period for VCT in Guangzhou?
The payoff period for the VCT is less than two years, based on a rate of 0.8 Yuan per kilowatt-hour of electricity. The majority of the TBSs in Guangzhou can be reconstructed. Provided that one thousand TBSs are reconstructed and VCT is applied, more than 3 million RMB will be saved annually in electricity bills. Table 3.
How much heat does a telecommunication equipment run a day?
The telecommunication equipments run all day with a total heat of 4.35 kW. The heat density of the lighting and the people were ignored due to the limited period of occupancy. The air conditioners operated continuously with a temperature set point of 25 C and a relative humidity set range between 5% and 85%.
