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.
