Munters Energy Comparison Study Modelling Information
This report presents the study undertaken for
Munters on the comparison of the energy and water
performance of the Munters OASIS/DCiE cooling
units against other traditional cooling methods,
namely legacy air cooled chiller, water cooled chiller,
and high efficiency air cooled chiller. The modelling is based on a representation of the
data centre electrical and cooling infrastructure.
The electrical infrastructure is composed of
electrical equipment to the IT whitespace, the
cooling system and other loads, such as BMS
system, lighting, etc.
This study focuses on the following
locations: Dubai and Abu Dhabi The cooling system consists of the cooling equipment
serving the IT whitespace, typically CRAH units and
associated chilled water cooling plant, mass air free
cooling units, and cooling equipment serving other
loads, such as split system for battery rooms, etc.
The analysis focuses on estimating energy and
water efficiency using the following metrics: Power
usage effectiveness (PUE): measured as the ratio
of estimated whole facility energy usage and IT
energy usage; Water usage effectiveness (WUE):
measured as the ratio of whole facility water usage
and IT energy usage. The metrics are analysed on
an annual basis.
A similar process is modelled for the water usage. The
modelled data centre is based on the following: two
data halls of design IT capacity of 1,000kW each;
Electrical distribution to the IT based on a 2N system
with 2(N+1) UPS module. n
