Head Pressure Control - Intelligent Modulation

(X Models) The system is tted with a voltage regulating fan speed controller which allows set point adjustment and system monitoring via the indoor unit microprocessor controller.

Introduction

A pressure transducer is tted to the liquid line which in turn feeds back the head pressure to the microprocessor. The condenser fan speed can then modulate via the controller to provide optimum control under varying ambient conditions. The head pressure can be monitored via the display keypad.

Units tted with thermostatic expansion valves (TEV) have the head pressure factory set to 26 Barg (377 psig).

Units tted with optional electronic expansion valves (EEV) have the head pressure factory set to 22 Barg (319 psig).

The head pressure can be monitored via the display keypad.

Low Noise Feature for Condenser Fan

(X Models) Specically designed for night time operation as optimum low noise levels are achieved with reduced ambient temperature and room loads, this feature is also ideal for residential and other outdoor noise critical applications.

Initiated by setting the microprocessor programmable time clock, the head pressure set point changes from the standard 26 barg (377 psig) (TEV) or 22 barg (319 psig) (optional EEV) to 34 barg (493 psig), reducing the outdoor unit fan speed and corresponding operating sound levels.

This feature is enabled by the inclusion of an optional clock card within the microprocessor.

Head Pressure Control -Intelligent Modulation

(WX Models) A 3 way regulating valve, electronically actuated via the microprocessor, utilises a liquid line pressure transducer to measure and adjust head pressure. The valve will allow cooling water to ow to the condenser, to bypass the condenser, or to allow water ow to both condenser and by-pass line in order to maintain correct refrigerant head pressure.

The head pressure can be monitored via the display keypad.

EasiCool™Precision Air Conditioning

Hot Gas Re-Heat (HGRH)

(X Models) The HGRH system consists of a heating coil and solenoid valve(s) and can be tted to units with humidication selected.

The microprocessor monitors the temperature and humidity setpoints and initiates HGRH to provide optimum system efciency. HGRH may be tted instead of electric heating or low pressure hot water.

During dehumidication, the hot gas re-heat coil re-heats the cooled air from the evaporator coil using hot gas from the discharge line to maintain the room setpoint. Normally reheating of the air during dehumidication is performed by electric heating which requires additional power input. By utilising the available hot gas, the HGRH option does not require additional power input and is therefore far more energy efcient than electric heating.

Introduction

Suction Throttle Valve

The valve can be selected for units tted with EEVs. An electrically operated suction throttle valve can be tted to provide accurate capacity control from 50% to 100% depending on the room load. Precise temperature control is obtained as a result of modulating the refrigerant ow in the evaporator by throttling the valve on the suction line.

Electronic Expansion Valves (EEV)

Electronic expansion valves differ to the normal thermostatic expansion valves in their ability to maintain control of the suction superheat at reduced head pressures. This can lead to signicant energy savings particularly at reduced loading and low ambient

Introduction

temperatures.

EEV step position, superheat setpoint, head pressure set point and other features can be viewed and adjusted via the microprocessor display.

Whilst offering versatile control at the full design duty of the unit, TEVs do not automatically optimise themselves to all operating conditions. Therefore, if the refrigeration system is operating at 40% or 50% of full load, especially at a lower ambient temperature than that for which the valve was sized, the conventional TEV must have the design head pressure available to ensure good refrigerant control. Maintaining an articially high condensing pressure is normal in conventional systems.

Using an EEV allows for good refrigeration control whilst operating at part load and lower ambient conditions with a reduced condensing pressure. By tting an EEV and adjusting the head pressure control setting an increase in the system EER (Energy Efciency Ratio) of up to 30% can typically be seen. The Mollier diagram shown below helps to illustrate how this increase in efciency is achieved.

EEV’s differ to normal thermostatic expansion valves in their ability to maintain control of refrigerant ow and the suction superheat at reduced head pressures. The turn-down rate of a typical EEV is superior to that of it’s thermostatic equivalent, such that a reduced optimum condensing pressure can be maintained at low compressor load. However low the load is on the compressor, from zero to 100%, there will not be a problem with turn down, even down to 10% of the valves rated capacity.

(AC Fan Motors Only Sizes 28 to 60) For applications where higher static air pressures are required, a larger fan and motor assembly size can be tted to replace the standard assembly and is available on most models.

Electronically Commutated (EC) Fan Motor

Sizes 6 - 60

Backward curved impellers, direct drive centrifugal fan assemblies with integral rotor mounted motor which is statically and dynamically balanced for quiet operation.

Designed for high corrosion resistance, the impellers are laser welded aluminium with a galvanised rotor and die cast aluminium EC power module.

EC motors incorporate integrated electronics to convert AC power to DC for efcient and accurate speed control and are adjustable via the microprocessor display keypad.

The fans offer maximum airow performance while keeping sound levels to a minimum.

Introduction

The fans are mounted within a oorstand complete with adjustable feet, optional legs and oor tile lip. (models DF28 - 60 only)

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.

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.

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.

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

Introduction

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 Field

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 EC 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.

Installation

Refrigeration Pipework

Oil Traps

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).

Pipe Supports

The following table identies the maximum distance between pipe supports on vertical and horizontal pipe runs.

Installation

Pipe O/D (inches) Support distance (m)

3/8 - 7/8” 1.0

1 1/8 - 2 1/8” 2.0

Lines passing through walls

Refrigerant lines that rub against solid objects wear holes in the copper pipework and cause leaks, the lines must pass through sleeved openings in such a manner that the lines do not touch.

Horizontal Sections

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

Discharge Risers

Consideration must be taken when designing vertical risers. Refrigerant velocity must be ensured in vertical risers at a minimum of 8m/s.

If required double risers must be designed into the system. Pipework must be sizes based upon a reduction in unit capacity as low as 30% of design. The double riser must be sized so that the refrigerant still maintains adequate velocity for the oil to travel around the system.

At part load the velocity is reduced in the larger diameter pipe (and cannot carry oil). An oil trap is formed forcing vapour up the smaller tube which still has adequate velocity due to its size to continue carrying oil around the system. The trap at the base of the riser must be as small as possible. This ensures that the trap causes a pressure drop causing vapour to pass up the smaller tube.

When the load increases the velocity of the refrigerant ensures that oil carries up both tubes.

CAUTION

Care must be taken in sizing double riser systems.

Liquid Line

If the system is congured with the EasiCool higher than the condenser unit it may be required to increase the degree of sub cooling to prevent ashing gas occurring in the liquid line. This ashing is due to excess pressure drop caused by the static head of liquid refrigerant and can results in poor operation of the evaporator and expansion device.

Careful pipe sizing is recommended to ensure that the liquid line does not have excessive pressure drop

Increasing the liquid line tube size can minimise pipe pressure drop.

However as a fail safe it is recommended that the condenser is installed above the indoor unit to allow for correct liquid drain.

Pipe Insulation

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 ash gas.

IMPORTANT

The pipe sizes/refrigerant charges quoted are for guidance only. It is the responsibility of the installing contractor/site engineer to check the pipe sizes/refrigerant charges are correct for each system installation and application. Split systems may require additional oil which should be added to the low side of each compressor. Design should be in accordance with accepted refrigeration practice to ensure good oil return to the compressor(s) under all normal operating conditions.

Calculation of Liquid Line Refrigerant Charge (kg)

The liquid line refrigerant charge can be calculated using the following equation:

LR = L x m

LR = Total Liquid Line Refrigerant Charge. (As calculated from above) IR = Indoor Unit Refrigerant Charge. OR = Outdoor Unit Refrigerant Charge.

Where: LR = Total Liquid Line Refrigerant charge (kg) L = Length of Interconnecting pipework (metres) m = Liquid Line Refrigerant charge / metre. Refer to Liquid Line Refrigerant Charge (kg/m), above.

Example

Indoor Unit Model Ref. = DF10X-EZRE Outdoor Unit Model Ref = CR16 Condenser Interconnecting Pipework = 10 metres

From the Refrigerant Pipe Sizing Guide, the liquid line size given for pipework length of 10 metres is:0.05kg/m

System Refrigerant Charge

SR = LR + IR + OR

Where:

Where: L = 10 metres m = 0.05 kg/m (Liquid Line Size = 3/8”)

LR = L x m

LR = 0.5 kg. (As calculated from above) IR = 1.0 kg OR = 2.7 kg

SR = 0.5 + 1.0 + 2.7

Therefore

LR = 10 x 0.05 = 0.5kg

System Refrigerant Charge

= 4.2 kg / Circuit

Liquid Sub Cooling

The degree of liquid sub cooling required to prevent ashing of liquid refrigerant can be calculated by the following method.

Subcooling = Condensing temperature — Saturation temperature (Nett pressure at expansion valve)

Given the following as an example:

• Refrigerant R410A

• Condensing temperature (54.4°C) equivalent condensing pressure at 54.4°C = 34 Bar

• Liquid lift 20m

• Piping friction loss 0.21 bar

• Losses through valves and ttings 0.5 Bar

Pressure Loss due to Liquid Lift

Where

= H x spl

H = Height (m) spl = Static pressure loss

= 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.

Installation

Total Pressure Loss in Liquid Line

TPL Liquid = PFL + Valves

Nett Pressure at Expansion Valve

= Condensing pressure - Total pressure loss in liquid line

= 34 - 3.01 = 30.99 bar

Sub Cooling Required

Where PFL = Pipe friction loss (0.21Bar) Valves = Losses through Valves and ttings

= 0.21 +0.5 + 2.3 Total pressure loss in liquid line = 3.01 Bar

Saturation temperature at the nett pressure at expansion valve (30.99 bar) = 52°C (from refrigerant tables)

=Condensing temperature - Saturation temperature

= 54.4 - 52 = 2.4 °C

Therefore liquid sub cooling required to prevent liquid ashing = 2.4 °C

Oil Charging Guide

In order to determine if a system requires additional oil to accommodate for long interconnecting pipe lines and oil traps, a simple calculation can be used to approximate the volume of oil required as follows:

Where

OT = (RC / 200) - (OC x 0.09)

OT = Additional Oil Charge / Circuit (kg) RC = Total Refrigerant Charge / Circuit (kg) OC = Total Compressor Oil Charge / Circuit (l)

Installation

This calculation is based on the following assumptions:

1) 10% of the total compressor oil charge enters the system

2) A specic gravity of 0.09 between oil and water

3) Oil is added at a rate of 5 grams per kilogram of refrigerant

Example What is the additional oil charge required per circuit for an DF10X-EZRE matched with a CR16 and a 3/8” 80m interconnecting liquid line?

Refrigerant charge of an DF10X - EZRE = 1.0 kg

Refrigerant charge of a CR50 = 2.7 kg

Interconnecting pipe line = 80 x 0.05 = 4.0 kg

Total system refrigerant charge = 1.0 + 2.7 + 4.0 = 7.7 kg

So,

OT = (RC / 200) - (OC x 0.09)

Compressor oil charge(s) = 1.2 litre

OT = (7.7 / 200) - (1.2 x 0.09)

OT = -0.07 litre

A negative value (as above) suggests that there is already sufcient oil in the system. You can calculate the maximum refrigerant charge for this system when additional oil charge is requiredas follows:

OT = (RC / 200) - (OC x 0.09) RC = OT + (OC x 0.09 x 200) RC = 0 + (1.2x 0.09 x 200) RC = 21.6 kg
