Abstract

Energy saving in air conditioners is a primary concern in building projects, since a large proportion of the energy consumption in building service equipment is caused by air conditioners. The energy-saving research in air conditioners focuses mostly on the chiller system and the associated control strategies. For air conditioners in buildings, the thermal control strategy to adjust the temperature set point is very easy to implement and very effective in energy saving. In this paper an energy consumption calculation model of a data center in South Africa is presented to estimate the energy consumptions of air conditioners when the temperature set points are 22 ◦C and 23 ◦C.
