Abstract: Based on the analysis of the environmental requirements and energy consumption characteristics of the telecommunication base station(TBS),the simulation model was established and the air conditioning power consumption for the TBS was calculated in the cities of China,where the climatic data can be found in the design handbook.Taking the sandwich panel with the thickness of 50 mm as the TBS envelope,the power consumption of an air conditioning coupled with or without a thermosyphon heat exchanger in the TBS and the energy saving potential for using ambient energy was calculated,and the energy saving rate was shown on the map of China by different colors.The results demonstrate that the operation mode of an air conditioning coupled with a thermosyphon heat exchanger for controlling the indoor temperature can bring enormous energy saving potential for the TBS located in China except the southern areas.
