The Liebert DSE system design also reduces or eliminates several of the power components associated with water economizers.
The fixed economizers are similar to the differential economizers except that return air conditions are assumed as a constant, such as 24[degrees]C (75[degrees]F) for return air temperature and 65 kJ/kga (28 Btu/lbma) for return air enthalpy.
Economizer systems typically use mixed-air temperature (MAT) measurements for feedback control of the outdoor and return-air dampers.
Economizers allow outside air to complement data center cooling systems and provide "free cooling" during colder months, significantly reducing energy usage and wear on some components in the cooling equipment.
