System Configurations
Dual Circuit
X2X2
The SmartCool X2X2 is an air cooled, direct
expansion (DX), double circuit system linked
to two separate, remotely mounted air cooled
condensers.
Optimised for heat transfer using energy
efficient refrigerant R410A in each circuit, the
X2X2 system is located within the conditioned
space, absorbing room heat and transferring it
outside to the condensers.
By using one or more same/dissimilar sized
scroll compressors across the X2X2 double
circuit, part load efficiency can be maximised
and capacity more precisely matched to
application.
SmartCoolTM – D
General
W2W2
Suitable for applications favouring reduced
refrigerant charges, the SmartCool W2W2 is a
double circuit system featuring, DX cooling
within the case and dry coolers outside.
Warm room air is passed through two
completely independent evaporator coils and
an integral plate condenser transfers the heat
load to the glycol solution which is then
channelled outside to two air cooled dry
coolers.

Precision Air Conditioning
SmartCoolTM - D
Dual Cool
General
X2C0
For redundancy in critical applications, the SmartCool
dual cool X2C0 offers two different cooling mediums,
air cooled DX and chilled water, within the same case.
The X2C0 system is managed by the Airetronix
microprocessor to select which medium acts as the
primary source of cooling or which acts as back-up,
should the primary source fail or is unable to cope with
the heat load.
Precision Air Conditioning
W2C0
For applications where a water cooled system is
preferred over air cooled, the SmartCool W2C0
comprises two different cooling mediums within the
same case: DX water cooled, as in the W2W2 system,
and chilled water, as in the C000 system.
The Airetronix microprocessor elects which medium
acts as the primary source of cooling and which as
back-up, if the primary source fails or is unable to cope
with the heat load.
W2F0
The W2F0 system includes a free-cooling coil in
conjunction with the evaporator. In low ambient
conditions, particularly in relation to the high
temperatures and continuous system operation of a
server environment, the W2F0 system will run with
minimum energy. At times of higher ambient,
sophisticated Airetronix controls technology will
modulate the 3-way water regulating valves to
transition from free cooling back to mechanical cooling.
Typically the SmartCool W2F0 single circuit freecooling system uses 46%* less energy than a standard
air cooled DX system.

Chilled Water
Precision Air Conditioning
C000
Where a chilled water single circuit system is preferred,
warm room air is blown across the efficient cooling coils
of the SmartCool C000 and the heat transferred to a
chilled water system such as Airedale’s high efficiency
TurboChill.
By controlling the 3-way water regulating valve, the
intelligent Airetronix microprocessor can achieve precise
control of temperature and humidity.
SmartCoolTM – D
General
C0C0
In the SmartCool C0C0 unit, the cooling coils are split
into two independent systems, each with a 3-way water
regulating valve, and cooled by chilled water from two
separate chillers.
For extra security, the dual circuit configuration of
SmartCool C0C0 offers 2N redundancy.

necessary oil separators employed.
Excessive pressure drop in liquid lines can cause poor refrigerant distribution to
expansion devices and can cause malfunction of the system (especially with condensers
lower than the evaporator)
For long vertical rises in both liquid and discharge lines, it is essential that oil traps are
located every 4m to ensure proper oil movement / entrapment. In addition there should be
an oil trap at the exit of the air handling unit before a vertical riser is applied (refer to
example below).

It is good practice to ensure a slight gradient toward the compressor in the direction of the
refrigerant flow for suction lines running horizontal. This assists oil return to the
compressor. A gradient of approximately 1:200 (0.5%) shall be used.

If the system is configured with the SmartCool higher than the condenser unit h it may
be required to increase the degree of sub cooling to prevent flashing gas. This flashing is
caused by excess pressure drop caused by the static head of refrigerant and can cause
poor operation of the evaporator and metering device.
Careful pipe sizing is recommended to ensure that the liquid does not form gas due to
excess pressure drop
Increasing the liquid line size minimizes pipe friction and flashing due to friction pressure
drop.
However as a fail safe it is recommended that the condenser is installed below the
indoor unit to allow for correct liquid drain.
The liquid line of the system must be insulated if passing through extremely warm places
(Boiler houses etc). Ensuring that the refrigerant does not become flash gas.

Liquid Sub Cooling
Precision Air Conditioning
The degree of liquid sub cooling required to prevent flashing of liquid refrigerant can be calculated by
the following method.
Given the following as an example:
· Refrigerant R410A
· Condensing temperature (54.4°C)
· Liquid lift 20m
· Piping friction loss 0.21 bar
· Losses through valves and fittings 0.5 Bar
1. Determine the pressure drop due to pipe friction = 0.21 Bar
2. Pressure drop due to valves and fittings = 0.5 Bar
3. Pressure loss due to liquid lift = height x 0.115 = 20 x 0.115 = 2.3 bar
Note:- At normal liquid temperatures the static pressure loss due to elevation at the top of a liquid lift
0.115 bar/m
Therefore:- Total pressure loss in liquid line = 3.01bar
Condensing pressure @ Condensing temperature (54.4°C) = 34 Bar
Total pressure loss in liquid line = 3.01 Bar
Nett pressure at Expansion valve = 34 - 3.01 = 30.99 bar
Saturation temperature at the Nett pressure at expansion valve (30.99 bar) = 52°C
(from Refrigerant tables)
SmartCoolTM – D
Installation
Sub cooling required
= Condensing temperature — Saturation temperature at the Nett pressure at expansion valve
= 54.4 - 52 = 2.4 °C
Therefore liquid sub cooling required to prevent liquid flashing = 2.4 °C

The dry cooler design duty is equivalent to the Total Heat of Rejection (THR) from the indoor unit.
This value can be taken from the performance data in the technical manual using the following.
Parameters required are:
· Ambient conditions (°C dB) Airedale recommend a 10°C lower than the EWT.
· Glycol content (%)
· Entering & leaving water/glycol temperatures (°C) (EWT and LWT)
· Mean condensing temperature (°C) Based on 5°C above leaving water/glycol temperature
The maximum design volumetric flow rate can be calculated using the following equation:

Cp = Specific heat capacity. Refer to table below.
The maximum indoor unit pressure drop can be calculated using the following equation:
DPs= DPw x Pc
Using the volumetric flow rate calculated above, the pressure drop (DPw) can be taken from the

1 The procedure should be carried out using a high vacuum pump. The pump should
be connected to the high and low pressure sides of the system via a gauge manifold
fitted with compound gauges. A high vacuum gauge should be fitted to the system at
the furthest point from the vacuum pump.
2 Triple evacuation should be used to ensure that all contaminants are removed or at
least reduced to significantly low proportions.
3 The vacuum pump should be operated until a pressure of 1.5 Torr (200 Pa) absolute
pressure is reached, at which time the vacuum pump should be stopped and the
vacuum broken with oxygen free nitrogen until the pressure rises above zero.
4 The above operation should be repeated a second time.
5 The system should then be evacuated a third time but this time to 0.5 Torr (absolute

2. Check operation and superheat readings are within acceptable limits.
3. Check suction and discharge pressure are within acceptable limits.
4. Check there is NO foaming in the compressor sight glass. This would indicate the

maximum operating pressure is 10 barg.
The chilled water pipework external to the unit is required to be pressure tested to ensure
water tightness.
The chilled water coils need to be bled of air prior to unit operation. The bleed valve is
positioned at the top of the coil; with access through the front door.
For the valve working pressure, please contact Airedale.
Air in a chilled water system may reduce the cooling performance of the unit. The required
pump power input would also be increased.
Humidification shall be provided by an electrode boiler. The sealed humidifier design shall
ensure that only clean sterile steam is supplied to the conditioned area and corrosive salts
and minerals are held in the disposable bottle. The steam shall be distributed through a
sparge pipe fitted to the coil assembly.
Featuring modulating capacity output control as standard, the system shall provide
continuous modulation of steam output in response to a proportional control signal. The
output control shall range is 20%-100% of the humidifier rated value and be designed to
give an approximate steam output of +/- 5% at 25°C (at the sensor), thus ensuring precise
control of the conditioned space.
The cylinder operating life time shall be automatically optimised via the integrated water
conductivity sensor, which combined with the controls shall monitor and
regulate the water refill cycle to reduce excessive salt deposits and the progressive wear of
the cylinder.
All humidifier parameters and alarms shall be accessible and adjustable via the

The location of the pump assembly
depends on the type of Floorstand. Front
or Rear discharge air.
The pump is positioned near to the outlet
of the Floorstand air discharge allowing
unrestricted condensate flow. (Front or
Rear of the unit)
The pipework supplied loose can be cut to allow unrestricted condensate flow from the
condensate and humidifier drain. The pipework fitted is connected to the condensate
drain with a compression fitting. The pipework locates into the pump through grommet
holes.
The flexible pipework clips are to be tightened sufficiently to maintain a water tight seal
during unit operation. Do not over tighten as this can damage the condensate hose.
The drain tray must be primed with water to ensure that the trap is full before the unit is
operated.
Check that the pipework and condensate drain tray do not leak water.
Check that the condensate pump operates correctly and that the maximum pumping
head of 10.8 m is not exceeded. Ensure that a tundish is used to ensure free flow of
condensate to customer drains and therefore cannot back feed when the pump is
turned off.

Control
Installation
Precision Air Conditioning
Constant pressure control is a method of controlling air pressure within a space, such as
a floor void or a duct. The air pressure is controlled using a variable speed fan that is
modulated to maintain a given set point.
Constant pressure control monitors the air pressure differential between two points. In a
typical application (shown below) the pressure under the raised floor (red) is compared
to the room pressure (blue).
Room

pressure
The two pressure points, positive and negative, are routed back to an air differential
pressure sensor inside the CRAC unit. The value from the air pressure sensor is
compared to the set point and a fan speed demand is generated, to maintain the
required pressure differential.
It is the responsibility of the installer to fit the air pressure sensor(s). The sensor shall be
located under the false floor with the 6mm flamtronix tubing routed back into the control
panel of the unit (the tubing must not be obstructed /damaged to ensure accurate
pressure control).
The constant pressure system shall be commissioned by Airedale following routing of
tubing from the pressure diffuser and the unit.
A maximum of 8m/s air velocity is allowed at the diffuser so consideration must be made
when locating the diffuser.
Constant air volume is a method of automatically adjusting the unit fan speed to deliver a
specific air volume.
When faced with a change in system resistance, the fan speed modulates to obtain the
air volume set point.
Constant air volume monitors the air pressure differential between two points. These two
pressure points, positive and negative, are routed back to an air differential pressure
sensor inside the unit

Addressing the Display Keypad
The address of the display keypad can be configured only after having connected the power supply, using the
RJ11 connection cable.
Controls
To access configuration mode, press the + + buttons together and hold them for at least 5
seconds; the screen shown below will be displayed, with the cursor flashing in the top left corner:
To change the address of the display keypad (display address setting), press the button once: the cursor will
move to the address field (nn).
Use the or buttons to select the desired value, and confirm by pressing again. If the value selected
is not the same as the one saved previously, the screen shown below will be displayed, and the new value will
be saved to the permanent memory. If the field nn is set to 0, the terminal will communicate with the pCO board
using “point-to-point” protocol (not pLAN) and the field “I/O Board address: xx” will not be displayed, as it has no
meaning.
