ASHRAE TC9.9 Research Priorities –
Summary from 21 Jan 2008 Meeting
At the 2008
Winter meeting, TC 9.9 developed a
consensus research plan to enable
evaluation of proposed research
topics whether they are solicited or
non-solicited. This plan is
designed to align with ASHRAE’s
Research Strategic Plan but also
to compliment ASHRAE’s Datacom
series of guidebooks, which were a
response to industry needs for data
center cooling. Many cooling issues
require a more thorough and detailed
analysis, thus the purpose of our
research plan. When considering
sponsorship of any research topic
the committee will refer to this
plan to ensure that TC9.9’s research
goals are met. Items highlighted in
bold
red are the TC’s
consensus highest priority items.

Energy
consumption effects driven by the
thermal guidelines (Humidity and
inlet temp.)
-
expansion of the thermal
guidelines – energy consumption
impact
- reliability
impact of expanding the RH/room
temp – recommended and allowed
-
Cooling proof of concepts
- Adaptation of data centers for multi-mode cooling – liquid, air, multiphase
-
Removing barriers to liquid
cooling
- Rating methods, free cooling techniques, metrics for comparison
- Optimal cooling
implementations for ITE
equipment based on power saving
- RAS impacts of various
cooling implementations at data
center level
- Optimal integration of data center cooling with ITE cooling
-
Uniformity/specification in
real-time data reporting between
ITE and data center management
- Metrics – (true) inlet air temperature, flow rate, total heat load, etc.
-
Standardized protocols for
data reporting
- Power saving modes for
ITE and integration with
data center management
- Optimization of data
center cooling parameters
for power-saving ITE
operation – flow and inlet
temperatures, workload
- Algorithms for managing
varying ITE demand
-
Airflow Management
-
Practical achievements for
fan to server flow ratios
-
Influences of aisle
containment
- Blank-off plates and
containment of cable
penetrations
- Selection of floor
diffusers
-
Integration
of telecom equipment within a
data center
- Considerations for
side-to-side-cooled ITE
- Mixed front-to-back/top
and side-to-side equipment
-
Matching of
ΔT’s between ITE and cooling
equipment in common
configurations
- Avoiding hot spots when
shutting off cooling units
-
Ride-through
when losing a chiller –
guidelines and sizing for
typical configurations
-
Guideline
for floor diffusers for cold
aisles
- Placement of cold aisle
diffusers and optimization
using adjustable diffusers
