ASHRAE - CELEBRATING 125 YEARS

industry and supported technically by EPRI and ASHRAE.
The utility industry has changed. Cool TES has evolved. In
addition to US installations of ice TES numbering in the
many thousands, and CHW TES (on average much larger)
and numbering in the many hundreds, there have been
many and growing Ice and CHW TES applications around
the world, including Canada, Mexico, Brazil, Europe, East
Asia, Southeast Asia, the Middle East, South Africa, and
Australia. The cool TES industry, in many ways mature
and thriving, exhibits increasing numbers of applications
for traditional peak electric load management. Those
applications primarily use either small- to large-scale iceon-coil TES or large-scale thermally stratified CHW TES.
But additionally, there has been significant growth in new
types of TES applications or new markets, notably:
* Large District Cooling (DC) systems in East Asia (using CHW TES or mostly ice-on-coil TES),
* Very large DC systems in the Middle East (using iceon-coil TES or mostly CHW TES); note that DEWA (Dubai
Electricity & Water Authority) requires that new DC
systems employ TES for at least 20% of peak capacity,

* Small-scale "rooftop" TES (using ~30 to 50 ton-hr
[105 500 to 175 843 Wh] direct-refrigerant Ice TES units),
* Emergency back-up cooling for Mission Critical
Facilities, such as data centers (using mostly small- to
medium-scale CHW TES),
* Turbine Inlet Cooling (TIC) of Combustion Turbine
power plants (using mostly large- to very large-scale
CHW TES),
* The use of hot TES, as many district heating systems
are converted from steam to hot water (using thermally
stratified HW TES), and
* Support for increased deployment of intermittent
renewable power sources, such as wind and solar (using
all types of TES, as TES unit capital costs, life expectancy,
and other performance characteristics are often far
superior to those of batteries or other energy storage
technology options).
Also, new TES technologies have continued to be developed, some beginning (or targeted) to capture new or
niche market applications, e.g.:
* Ice slurry for cooling of human bodies and organs

The Top 5 Reasons Data Centers
Are Designing With Heat Pipes
These are just a few of the reasons data centers are using heat pipes to
handle heat & reduce PUE's...
Passively reject heat to the outside using gravity NOT power
Reduce the load on CRAC units
No electrical loads to worry about
No moving parts means better reliability
Zero contamination of data center air
