Research On The Performance Of Telecommunication Base Station With Separate Heat Pipe

With the global attention to the energy consumption, the energy saving of telecommunication base station (TBS) have already become the focus both for the refrigeration industry and the telecommunication industry. Number of the TBS in china has over 1.2 million, which will dramatically increase with the expansion of 3G services. TBS consumed about 15.08 billion degree of power in 2009, and air-conditioning take up about 69.4 billion degree. Energy saving of the TBS has become the focus of national energy strategy. Air-conditioning system of TBS needs to 24 hours operate in order to ensure the environment temperature and humidity. In this paper, energy saving potential of TBS has been studied. In order to achieve the energy saving purpose, TBS with separate heat pipe is proposed.Inappropriate envelope, bad air distribution and uninterrupted air conditioning operating are the main reasons which lead to the high energy consumption of TBS .The main contents and conclusions are as followings:1) A heat load of the TBS calculating model is established. With the help of the envelope experiment data and the calculation software, the load and the energy-consumption of the TBS in typical cities can be worked out on several conditions.2)Three different forms of organization of airflow were established. CFD simulation was used to optimize the airflow distribution of the TBS in order to improve the energy utilization.3) In order to make full use of the outdoor cold source, separate heat pipe with Micro-channel was experimentally investigated on different conditions. TBS with separate heat pipe was experimentally studied on several different conditions. The COP range of the TBS with separate heat pipe is from 4.66 to 13.9, the average COP is up to 9.05 when average outdoor temperature is 20oC, while the average COP is 6.23 when average outdoor temperature is 27oC. Compressor of Air-conditioning occupies about 39.1% of the total running time and the PUE value is up to 1.71. The energy-saving rate of the new TBS can reach 44.7%. This system can save lots of energy. 5) TBS with separate heat pipe is equipped with a special solar power system. It is shown that the solar power system can basically meet the load demand for two fans of the TBS.
