Environmental Considerations
Freeze Protection
Airedale recommends the following actions to help protect the unit during low temperature operation. This also includes
Introduction
the units subject to low ambient temperatures.
Units with supply water temperatures below +5°C
Glycol is recommended when a supply water temperature of +5°C or below is required or when static water can be exposed to freezing temperatures.
Units subject to ambient temperatures lower than 0°C
Glycol of an appropriate concentration (1) is used within the system to ensure adequate protection. Please ensure that the concentration is capable of protection at least 3°C lower than ambient.
Water / glycol solution is constantly circulated through all waterside pipe work and coils to avoid static water from freezing.
Ensure that pumps are started and running even during shut down periods, when the ambient is within 3°C of the solution freeze point (1) (i.e. if the solution freezes at 0°C, the pump must be operating at 3°C ambient).
(1) Refer to your glycol supplier for details

Introduction
The fans are mounted within a oorstand complete with adjustable feet, optional legs and oor tile lip.
Electronically Commutated (EC) Fan Motor Option
EC motors are DC motors with integrated AC to DC conversion; this gives the exibility of connecting to AC mains with the efciency and simple speed control of a DC motor. The EC fan offers signicant power reduction in comparison with equivalent AC fan at both full and modulated fan speeds. The inbuilt EC fan control module allows for fan speed modulation from 15-100%, a standard AC fans modulating range is typically 40 to 100% of full fan speed.
The EC fan presents superior energy efciency at full and reduced fan speed compared to the equivalent AC fan motor.
Standard voltage regulated (VR) fan speed controllers offer a linear response. By comparison the EC fan is adjusted on demand via the unit microprocessor with precision, offering substantial energy savings.
The following illustration shows a comparison of the typical power input required by each method.

Humidier - Intelligent Modulation
Humidication is provided by an electrode boiler. The sealed humidier design ensures that only clean sterile steam is supplied to the conditioned area and corrosive salts and minerals are held in the disposable bottle. The steam is distributed through a sparge pipe tted to the coil assembly.
Introduction
Featuring modulating capacity output control as standard, the system provides continuous modulation of steam output in response to a proportional control signal. The output control range is 20%-100% of the humidier rated value and is designed to give an approximate steam output of +/- 3% at 25°C at the sensor, thus ensuring precise control of the conditioned space.
The cylinder operating life time is automatically optimised via the integrated water conductivity sensor, which combined with the controls monitors and regulates the water rell cycle to reduce excessive salt deposits and the progressive wear of the cylinder.
All humidier parameters and alarms are accessible and adjustable via the microprocessor display keypad unit, main features include:
• Supply water conductivity (µS/cm)
• Actual steam output (kg/h)
• Required steam output (kg/h)
• Actual current rating (A)
• Required current rating (A)
• Status mode (Start Up, Running, Filling, Draining)
Water Conductivity & Cylinder Type Conductivity is a measure of the ability of water to pass an electric current, measured in micro Siemens / centimetre (µS/cm). 3 different cylinders are available which correspond to the supply water conductivity.
Matching the correct cylinder type with the conductivity of the supply water ensures optimum performance and increases the life span of the cylinder.
1 Low Conductivity (Soft Water) 100 to 350 µS/cm 2 Standard Conductivity (Moderate/Hard Water) 350 to 750 µS/cm 3 High Conductivity (Very Hard Water) 750 to 1250 µS/cm
As standard the humidier is tted with the standard conductivity cylinder which covers the majority of water supplies. Where the water conductivity is known, please specify at order. For further details please contact Airedale.
CAUTION
The supply water pressure to the humidier assembly must be between 1 - 8 barg.
16
EasiCool™Precision Air Conditioning
Humidication
Control Principles
In a humidier with electrodes, steam shall be produced by passing a current between electrode plates to generate heat. The higher the current being passed between the electrodes, the greater the quantity of steam that is produced. To modulate the rate of steam production, this system shall vary the level of water within the cylinder, thereby increasing the immersion level of the electrodes and the current being passed between them. The more conducting area that is available to pass current between the electrodes, the larger the amount of steam that shall be produced.
Modulated by the controller, the water level is varied so that the level of steam being produced ensures that the room humidity set-point is continually maintained within a tight tolerance.
Optimised Lifetime
The life span of the Airedale humidication system shall be optimised by the inclusion of a water conductivity sensor into the bottle feed. This sensor shal determine the conductivity level of the supply water and by using an algorithm embedded in the software, determines the frequency that the bottle should be drained.
Example: (Optimised Lifetime with High Water Conductivity Supply) As liquid water is boiled off into steam, mineral deposits are left in solution increasing the conductivity of the water. To counter this, the intelligent software increases the frequency of drain meaning that the replenishing supply water keeps the concentration of minerals diluted. By maintaining an acceptable mineral concentration, the bottle life span is maximised.
Introduction
De-humidication
(With Electric Heating and Humidication only) Controlled by the microprocessor the de-humidication feature reduces fan speeds by 20% (adjustable). The reduction of fan speed increases de-humidication which means that the time taken to reduce the room humidity to the required level is drastically decreased, along with the energy required to do so.
The return temperature is monitored during de-humidication to ensure that the temperature does not fall to a critical level. If the temperature reaches the low limit de-humidication is cancelled until the return air temperature increases.
Rapid De-humidication
Controlled by the microprocessor, electronic expansion valves are unlike their conventional thermostatic counterparts in that they can modulate independently of the suction line temperature. This unique feature allows the controller to raise the superheat set-point, in turn dropping the evaporating temperature to a point at which considerable de-humidication takes place.

Condensate and Humidier
All drain trays are tted with their own trap assembly. Condensate drain may be run to waste via ordinary plastic waste pipe. Humidier drain may be run to waste via pipe suitable for liquid temperatures of 100°C. All drain pipework operating under gravity should be sloped away from the equipment and the gradient should be made as steep as possible. Suitable rodding positions should be incorporated particularly if the run is long.
Water Conductivity
As standard the humidier is tted with the standard conductivity cylinder which covers the majority of water supplies. Low and High conductivity options can be specied at order.
Safe Operation of Humidier
To protect the humidier bottle from dangerous pressures in event of the steam supply pipe becoming blocked, a tundish is installed between the water inlet solenoid and the cylinder to act as a reservoir and to feed water to the humidier inlet manifold as required.
CAUTION
An overow weir is incorporated in the common ll/drain tundish. Any pressure build up in the cylinder would be allowed to vent through the tundish to atmosphere. It is MOST IMPORTANT that the steam distribution pipe is not damaged or kinked at any time to avoid the risk of unacceptably high pressure building up in the electrode bottle.

Sound Measurement Method
Measurement Of Sound Power
All sound data quoted has been measured in the third-octave band limited values, using a Real Time Analyser calibrated sound intensity meter in accordance with BS EN ISO9614 Part 1 : 1995.
All Sound Power Levels quoted are calculated from measured sound intensity according to BS EN ISO9614 Part 1 :
1995.
Semi hemispherical
Sound Pressure Levels are calculated from sound power using the semi-hemispherical method where the noise source is in junction with 2 boundaries i.e. the oor and 1 wall.
Free eld
For comparison, the semi hemispherical gures can typically be reduced by 3dB to provide free eld conditions.
IMPORTANT
The sound data quoted is based on the unit having a ducted return air, ducted (or underoor) discharge air and standard forward curved fan and AC motors tted, refer to illustration below.
Case breakout sound data is therefore independent of the discharge air and return air sound data.
For non-ducted return air applications, the overall case breakout sound levels may increase, due to the return air sound being predominant. Within the conditioned space, sound from in-room ducted discharge air grilles and other equipment will contribute to the overall sound level and should therefore be considered as part of sound calculations.
Specialist acoustic advice is recommended for noise critical applications.
