Reducing Electric Power Consumption for Air Conditioning by Improving Temperature Distribution in Telecom Equipment Rooms

This article presents the results of an electric-power-reduction experiment that was conducted in collaboration with the NTT WEST Kochi branch.One effective way to reduce the amount of electric power required for air conditioning in a telecom equipment room (TER) is to eliminate hot spots.In the experiment, the causes of two hot spots generated in the existing TER were analyzed, and various heatcontrol methods were implemented to eliminate them.Then the effects these methods had on reducing the temperature and on reducing the required air conditioning power were evaluated.
