Introduction
Infrastructure cooling
To serve the increasing digital and mobile data
requirements of businesses and online consumers,
the IT equipment, telecom and server infrastructure
have to function round the clock. Unexpected or
unplanned downtime is not only costly to businesses
but also impacts end-consumers who depend on the
continuous access to data connections for day-to-day
›› For rooms and
enclosures
that require
round-the-clock
cooling
›› Where continuous uptime
is the absolute requirement for
›› server data protection
›› equipment protection
activities. 24/7 operations of the infrastructure in
turn increase the heat loads generated within the
IT/server rooms and telecom shelters. Therefore your
business infrastructure requires reliable, efficient
and flexible cooling to ensure maximum uptime
while offering the best return on investment.

Introduction
Infrastructure cooling
Understanding the mission-critical cooling application environment
Comfort cooling
Infrastructure cooling
- Humidity is present
- Balanced sensible and latent capacity
- No or limited humidity
- Pure sensible capacity
 60-70% temperature control
 30-40% humidity control
 80-90% temperature control
 10-20% humidity control
Low humidity
levels
Constant cooling
set at 20-22°C
Unlike a normal living environment, a typical server
room or technology infrastructure environment
does not generate or minimally generates
humidity and moisture. Continuous cooling of
such rooms also removes the humidity. Average
relative humidity (RH) levels in server rooms or
infrastructure rooms are lower than 30%.
›› Protection of server equipment and back up power
supply
›› Emergency power supply lifetime is temperature
dependant
›› There is adequate buffer to compensate
a potential rise in temperature
›› In general, servers and other equipment
infrastructure fluctuate in activity, so have increased
flexibility to maintain constant temperature level
These low humidity levels reduce the ability
to transfer heat loads (to cool down the server
rooms). Therefore the need to boost the
cooling capacity of the indoor system.
Need for a reliable
backup system
Correct system
selection is critical
›› When a failure occurs (error or shutdown by the
temperature protection function), a dependable
backup system should take over instantly
›› Flexible control is needed to improve
the reliability of the backup system
›› Failure of the cooling system to provide the
required capacity at any time can lead to
infrastructure downtime and result in business costs
›› It is critical to install the right combination of
a split cooling system which can guarantee
reliable operation 24/7, year-round

Daikin solution overview
Boosted capacity indoor systems
High reliability at lower running costs for infrastructure cooling
Split air conditioning systems for normal comfort
cooling applications usually combine indoor systems
with matching capacities, or multiple indoor systems
with capacities lower than the outdoor system’s
capacity. This works because the indoor system’s
cooling capacity is sufficient to handle the higher
humidity conditions and varying indoor temperature
requirements that are common in a normal living
environment.
Applying this design logic to infrastructure
cooling environments can lead to risky situations
that might compromise overall system reliability
and frequent downtimes of 15 minutes.
Indoor systems for infrastructure cooling
environments need enhanced capabilities for
continuous heat transfer because they work
harder to extract energy by cooling dry air.
Daikin recommends and offers asymmetric
combinations (boosted capacity indoor
combinations: e.g. 71 class outdoor + 100 class indoor).
With Daikin Sky Air, you benefit from boosted
capacity system combinations for infrastructure
cooling. You can now confidently combine
indoor systems with higher capacities than the
outdoor system. This will boost heat transfer inside
the technology or server room environments.

Select your infrastructure cooling system in 2 steps
No humidity generation in room
(eg: Server room)
Some humidity source in room
(eg: Laboratory)
STEP 1
Determine
requested indoor
conditions
and required
cooling demand
(Sensible and
Total capacity)
IT room requires 22°C inside. It will have 7kW of sensible
cooling demand, and no latent cooling demand (no
humidity generation) throughout the year.
Ceiling suspended indoor unit is the customer's
preference for the server room.
Lab requires 22°C inside. It will have 9 kW of sensible
cooling demand, and some humidity generation in
the room (est. indoor humidity level 42%).
Wall mounted indoor unit is the customer’s
preference for the laboratory.
Indoor temperature = 22°CDB
Sensible cooling demand (SHC) = 7 kW
Latent cooling demand (LC) = 0 kW*
Total cooling demand (TC) = SHC + LC = 7 kW
Outdoor temperature operating range = -15°C ~ +40°C
Most stringent outdoor unit capacity condition = -15°C
Indoor temperature = 22°CDB
Indoor Relative Humidity (RH%) = 42%**
Sensible cooling demand (SHC) = 9 kW
Latent cooling demand (LC) = 0.9 kW
Total cooling demand (TC) = SHC + LC = 9.9 kW
Outdoor temperature operating range = -10°C ~ +40°C
Most stringent outdoor unit capacity condition = -10°C
STEP 2

solution
Boosted capacity indoor combination
with 12.5kW outdoor system.
Select the system
combination from
the given table,
where the system ‘s
sensible and total
capacity meets the
cooling demand
at the requested
indoor and outdoor
temperatures.
RZQG100L8Y1/ FHQ140CB
Total capacity = 7.48 kW
Sensible capacity = 7.48 kW
Power input = 0.42 x 2.49 = 1.04 kW
* If there is no latent cooling demand, look for conditions where
TC = SHC, since no more dehumidification will occur and thus the
indoor environment will stabilize. When TC > SHC and there is no
humidity generation, the indoor humidity will gradually decrease.
RZQG125L9V1/ FAQ71C9 x 2
Total capacity = 10.45 kW
Sensible capacity = 9.34 kW
Power input = 0.48 x 3.69 = 1.78 kW
** System capacity at 42%RH (14,2°CWB) can be found by interpolation between 13°CWB (35%) and 15°CWB (48%).

Notes
1. The ratings shown are net capacities
and include a deduction for indoor
fan motor heat.
2. The capacities are based on
the following conditions:
›› Outdoor air: 85% RH
›› Corresponding refrigerant
piping length: 5.0 m
›› Level difference: 0m
3. CPI is a percentage value compared
to the rated value of 1.00
4. For infrastructure cooling applications,
it is recommended to use remote
controller setting 16(26)-2-03
5. The error rate for this value is less
than 5% and depends on the indoor
unit type
6. The rated power inputs (PI) for each
model are listed in the table above

Daikin solution overview
Free cooling
Lower energy consumption
Ensuring uptime for infrastructure cooling
applications comes at the cost of higher energy
consumption than in comfort cooling applications.
Daikin Sky Air infrastructure cooling systems offer
you a leading solution for year-round efficiency, while
decreasing your running costs.
The energy savings potential of operating in free
cooling mode in certain climates is an attractive
proposition for continuous cooling environments.
Operating in free cooling mode saves energy
by using outdoor air during colder months,
which allows refrigerant-based cooling
components such as compressors to be shut off
or to operate at a reduced capacity.
Daikin Sky Air Seasonal Smart single phase
outdoor series provides a control signal that is
intelligently based on:
›› the indoor set temperature
›› the actual indoor temperature
›› the outdoor temperature

iTM solution
Continuous cooling operation
Avoid downtimes with specific system settings:
In low humidity environments indoor unit freezeup is less likely. The setting 16(26)-2-03 allows you
to boost the indoor capacity and enables quick
restart conditions in case of freeze-up prevention.
Daikin recommends to enable
16(26)-2-03 for infrastructure
cooling applications
Built-in settings for improved operational reliability
When using standard AC systems for infrastructure cooling, frequent start / stop cycles
of the compressor can occur due to:
1. incorrect selection / sizing of equipment
The typical solution:
›› oversizing the air conditioning equipment to
allow flexibility in server room occupancy
›› oversizing by building in some
spare, ‘safety’ capacity
›› using rules of thumb as calculation method
2. installation/application related difficulties
›› restricted air circulation
›› blockage of air distribution from
top blow server racks
Compressor and thermostat control are therefore optimized for infrastructure cooling
The new setting available on the
Seasonal Smart* L9 single-phase series allows the
outdoor system to gradually start. This prevents
the outdoor system from going into thermo-off while
still in start-up mode. This setting limits frequent
on/off operation. By lowering the frequency of
the compressor (and subsequently the capacity),
the system modulates and avoids early thermo-off
16(26)-7-02 (setting).
14
ON/OFF differential prevents the output from making
fast, continuous switches. Using the 16-7-02 setting
activates a larger thermo on/off hysteresis to enhance
continuous operation.
16 (26)-7-01: DEFAULT (Comfort cooling)
16 (26)-7-02: enhanced slow start + increased hysteresis
This setting must always be combined
with the EDP setting 16(26)-2-03.

Application guidelines
Best practice
for cassette units
how to apply cassette type cooling systems
in laboratories and other technical facilities
Flat floor or double floor not used for air distribution
Cassette type systems should only be used for
specific room configurations where central ceiling
installation is most suited for hot aisle/ cold aisle
arrangements.
With cassette units
Lab
equipment
In a laboratory environment for example, when the
cassette system is placed centrally on the ceiling and
above the aisles, it will allow maximum uniform air
distribution around the room.
It is not recommended to install cassette units
right above a server or machine.

Pair, Twin, Triple, Double Twin
Industry leading technology for commercial applications
and infrastructure cooling
ʯʯ Best in class efficiency:
-- Daikin designed and manufactured swing compressor
that ensures high reliability in continuous operation
-- control logic that optimises efficiency for the most
frequently encountered operating conditions and
auxiliary modes (when the unit is not active)
-- heat exchangers that optimise the refrigerant flow at the
most frequent operating conditions (temperature and load)
ʯʯ Variable Refrigerant Temperature: top seasonal efficiency
throughout the year and quick reaction speed to deliver required
cooling capacity in hot temperatures
