The Effect of Free Cooling on Reducing Total Energy

Consumption for Telecommunication Base Stations Specialist, Dantherm Cooling AB

Abstract

The number of telecommunication base stations is increasing all over the world due to an ever

increasing communication demand. As a result, energy savings play an important role in our

future and sustainable network architecture. In a typical base station, electronics cooling

normally accounts for 25-50% of the total energy consumption, traditionally provided by air

conditioning systems. The service life of air conditioning systems can be considerably reduced

by applying energy-efficient free cooling systems to the cooling setup. For an indoor

temperature set point of 25 °C, free cooling can cover 16-93% of the total cooling demand

depending on the location of the base stations. When adjusting to a higher indoor temperature

set point, the savings will increase accordingly.
