HEAT REJECTION OPTIONS

• Air cooled direct expansion system (DXA) includes throttle, evaporator coil,

scroll compressor and refrigeration piping configuration.

• Heat from the indoor air is transferred to the refrigerant at the evaporator coil

and rejected to the outside air via the air-cooled condenser.

• Indoor unit: OPTIMA-INV.(DFC.)DXA

• Outdoor unit: AMAE series air-cooled condenser

• The FC.DXA unit is a dual-circuit system combining DXA heat-rejection with

indirect free cooling (FC). The circuits are independent.

• When there is a call for cooling, and the difference between indoor and

ambient temperatures is acceptable, the FC unit will run to provide indirect

free cooling through rejecting heat via a dry cooler. Only when free cooling

capacity is insufficient to meet the cooling demand will the DXA unit start up

mechanical cooling. Reduced run hours of the DXA system through the use of

the FC unit saves energy.

• Indoor unit: OPTIMA-INV-FC.DXA

• Outdoor unit: AMAE air cooled condenser, CMEH dry cooler,PUG pump kit.

• The DC.DXA unit is a dual-circuit system offering both DXA (air cooled)

mechanical cooling and chilled water cooling (CW). It contains two independent

cooling circuits with different heat-rejection methods for redundancy.

• Indoor unit: OPTIMA-INV-DC.DXA

• Outdoor unit: AMAE air cooled condenser,PUG pump kit, user supplied chilled

water source.

cooled with direct free cooling (DFC), DX air cooled with

indirect free cooling (FC) and double cooling sources (DC).

Options are available to suit all installation requirements.

Supply air arrangements include top discharge (up flow)

and bottom discharge (down flow). Return air arrangements,

include top return, bottom return, front return and rear return

to meet all varied requirements of ICT sites.

The unit framework is provided with corrosion protection

treatment. The treatment is sufficient to provide protection

for a 15 year life cycle for inland installation.

If necessary, the treatment for sea air environment can be

supplied as an option.

The technical compartment housing the compressor,

humidifier, control and safety devices is separates from the air

flow, enabling ordinary service and preventive maintenance

to occur during operation.

Highly efficient EC fans are supplied with OPTIMA products.

OPTIMA-INV units are equipped with s scroll inverter

compressor which can vary speed continuously according to

the cooling demand.

A washable, easy maintainable and durable G4 class air

filter is a standard configuration for the OPTIMA range. With

optional air pressure switch, a clogged filter alarm can be

triggered when the filter is dirty.

The unit is installed with a pressure sensor which is used

for the fan speed control of the outdoor unit, therefore

maintaining refrigeration system pressure within a suitable

range and ensuring the stable operation of the system.

When compared to On/Off condensing control, the OPTIMA

system increases the energy saving significantly and extends

the working life of the compressor. It also enables the unit to

startup and work at low ambient temperatures (to -40 °F(-40

°C) or lower).

The dehumidification process occurs through decreasing the evaporator coil surface temperature or reducing the air flow

across the coil. These features enable faster dehumidification, increased energy savings and more precise humidity control.

An electrode humidifier, controlled by a microprocessor, monitors and adjusts the humidifying capacity precisely, while the

water quality monitoring and wash extends the maintenance interval, prolonging the working life of the unit.

The construction of the electric heater element (stainless steel pipe with wrapped fins) allows for a reduced operating

temperature, therefore eliminating ionization, and avoiding unpleasant odors.

All the electrical and control components are installed in an isolated control panel with orderly wiring and clear labeling,

meeting the IEC standards.

All the microprocessor-connected components are continuously monitored and controlled and, in case of malfunction, the

unit is shut down and the fault is shown on the display.

ENERGY SAVING TECHNOLOGIES

OPTIONAL ENERGY SAVING RUNNING MODESOptional Energy Saving Running ModesThe OPTIMA family of products offers two running modes which may be

chosen from the controller display:

Standard running mode: In this mode, the temperature and humidity are controlled within narrower

ranges;

Energy saving mode: In this mode, good energy savings can be achieved through allowing the

temperature and humidity to be controlled within wider ranges.

ELECTRONICALLY COMMUTATED (EC) FANS

Energy EfficiencyEC fans have brushless DC motors and integrated control

modules. Motor efficiencies of 85-90% are achievable; 30%

to 50% higher than traditional AC fans.

The difference in energy efficiency between variable speed

EC fan control and traditional on/off fixed speed AC fans can

be seen in the graph; the bars show the power consumption

of fans which are switched in gradually as required while

the blue curve shows the power consumption with infinitely

variable speed control.

Supply air temperature control, as the name suggests, means

driving the operation of the compressor based on the air

temperature at the supply air discharge location; when

cool air is being supplied at the setpoint temperature, the

compressor is stopped until supply air temperature begins to

increase. This control method provides accurate adjustment

of the cooling capacity according to actual demand and can

save a considerable amount of energy.

Supply air temperature control is typically applied to cold

aisle cooling systems. As the cold aisle temperature profile

is uniform (i.e. there is no short-circuiting of air), accurate

reading of the supply air temperature is simple to obtain from

the unit supply air discharge location.

Because the supply air and cold aisle air temperatures are

equal, the cold air is supplied directly to the equipment

requiring cooling and no energy is wasted cooling the rest

of the room. Compared to return air temperature control

systems, supply air control systems can operate at a higher

supply air temperature under the same cooling demand

conditions. As well as this, evaporating temperatures will

typically be higher and therefore more energy efficient.

For down flow units utilizing supply air temperature control,

the differential air pressure can be monitored to ensure the

cool air has been evenly distributed to all the servers.

Lower NoiseIn a given installation, switching off half the fans (and halving the air flow) will

typically only reduce the generated noise by approximately 3dB. Compare this

to EC fans, where reducing fan speed to provide half the air flow typically yields

an reduction of approximately 15dB. This is possible as EC fans are able to

operate across an infinitely controllable speed range, which in turn effectively

avoids electromagnetic and rectifier noise (generated by other traditional

motor and speed control devices), thus reducing the overall noise level.

In the graph, the bars indicate the sound pressure level of fans which are

switched in gradually as required and the blue curve shows the sound

pressure level with infinitely variable speed control.

As can be seen from the picture EC fan sound pressure level is 12dB lower

compared to the traditional AC fan.

Compact, Integrated Electronic Control SystemAll EC fans have dedicated speed control modules and filters built into the

motor assembly, making for a compact and self-contained solution. All that

is required is to connect the main power supply and the sensor signals to

the controller for complete speed control of between 10% and 100%. EC fans

provide a simple, convenient solution and can also support group control

and remote monitoring.

More Precise Temperature ControlCompared to a fixed-frequency compressor, an inverter compressor can

achieve more precise temperature control through maintaining the room

temperature closer to the setpoint temperature. The control accuracy can be

as close as ± 0.9 °F(±0.5°C), even when the load is constantly changing. The

comparison between fixed-frequency and inverter compressor temperature

control accuracy is shown on the right picture.

High Efficiencies, Lower NoiseCompared to the on/off operation of fixed-speed compressors, inverter

compressors have stepless speed changes which, through intelligent control,

consistently aim to run at the most efficient operating point . This variable

frequency operation can save nearly 30% on operating costs.

Results from an AIRSYS performance test of fixed-frequency vs. inverter

compressors can be seen in the graph; the stark difference between

compressor COPs is easily seen.

Additionally, an inverter compressor starting current is only about 10% of

that of a fixed-frequency compressor, they typically have a higher reliability

and the noise generated at part load is approximately 5-10 dB lower.

INVERTER TECHNOLOGY

OPTIMA-INV inverter series precision air conditioners adopt energy-

efficient DC inverter scroll compressors that can achieve stepless

speed and on-demand cooling capacity adjustment to achieve the

greatest efficiencies. Inverter technology is available with direct

expansion air-cooled (DXA) type units.

The inverter system manages the compressor speed with infinitely

variable control according to the actual cooling demand;. When the

difference between room and setpoint temperatures is high, the

compressor operates at a high speed (and greater cooling capacity).

As the temperature difference reduces, the compressor speed

gradually reduces to more accurately maintain room temperature (a

subsequently conserving energy).

OPTIMA-INV Inverter Series precision air conditioners utilize

electronic expansion valves to regulate the refrigerant flow entering

the evaporator and match it to the running speed of the compressor.

Compared to thermal expansion valves, electronic expansion valves

control much more accurately and efficiently. They are also able

to control system evaporation temperature and superheat more

effectively and lead to an overall higher system efficiency.

Data center power consumption is generally divided between four major sources; IT equipment, cooling systems, backup

power and lighting systems. The specific proportions are different in each data centers, however a typical split is presented

here.

As the pie chart show, the energy consumption of the cooling system is second only to the actual IT equipment; i.e. the air

conditioning systems account for a large portion of the total energy consumption of the data center. Therefore, by taking

advantage of free cooling solutions (and hence reducing the run hours of the compressors) large energy savings are potentially

achievable. AIRSYS has developed both direct and indirect free cooling systems, as well as dual heat-rejection mode units

which can significantly reduce the overall energy consumption of a data center. Options are available or configurable to suit

any and all installation requirements.

ELECTRONIC EXPANSION VALVE (EEV) TECHNOLOGY

INDIRECT FREE COOLING

DUAL COOLING SOURCES

Indirect free cooling refers to heat-rejection through circulating water between an indoor cooling coil and an outdoor dry

cooler or cooling tower; the water absorbs the heat at the indoor coil and then discharges it to the atmosphere via the dry

cooler or cooling tower.

By adding a water coil to the direct-expansion evaporator

coil and completing an indirect free cooling (FC) circuit with

a dry cooler or cooling tower, significant energy savings

can be made through a reduction in the DX compressor run

hours. When there is a call for cooling, and the difference

between indoor and ambient temperatures is acceptable,

the FC system will run to provide indirect free cooling. If the

FC system can not satisfy the total cooling demand, the DX

cooling system will commence operation, however, as the

outdoor ambient temperature decreases, the proportion of

FC capacity will increase. When free cooling capacity reaches

100%, and cooling demand is being met, complete FC mode

is achieved and there is no compressor power consumption

from the DX system.

OPTIMA-INV units can accommodate the indirect free cooling

option. The corresponding series are OPTIMA-INV-FC.DXA.

The schematic diagram showing the principle of operation

for an air cooled direct expansion unit with indirect free

cooling (FC) is as follows:

Dual cooling (DC) source units are supplied with two fully

independent cooling circuits; chilled water system cooling

(default) and mechanical (DX) cooling (supplementary).

Where a chilled water system is always available for heat

rejections, the unit will always run in chilled water cooling

mode. Only when chilled water cooling can not meet the

cooling demand will the microprocessor controller switch

from chilled water cooling to DX cooling. Where a chilled

water system is not always available (e.g. seasonal plant

operation), chilled water cooling will only occur when the

system is available.

As heat rejection via chilled water is prioritized, run time for

the DX cooling system is minimized resulting in an extend life

expectancy of the compressor corresponding energy savings.

19

DC units have an inherently higher reliability (due to inbuilt redundancy) and can ensure that cooling is more consistently

available. They also have the intelligence to select the most efficient operation mode depending on the environment, which

can greatly reduce energy consumption.

OPTIMA-INV units can accommodate dual cooling options. The corresponding series names are OPTIMA-INV-DC.DXA.

The schematic diagram showing the principle of operation for an air cooled DX dual cooling system is as follows:

For installations where outdoor temperatures are commonly lower than indoor temperature, fresh air can be introduced

directly into the room to cool the equipment; this is known as direct free cooling (DFC). A well designed and integrated DFC

system can greatly reduce the dependency on other cooling systems and save energy through minimizing their run hours.

DFC systems can be integrated with OPTIMA-INV units, with up flow and down flow configurations. The corresponding series

names are OPTIMA-INV-DFC. The diagram showing the arrangement and principle for direct free cooling options is as follows:

OPTIMA-INV-DFC systems include mechanical (DX) cooling and free cooling modes, together with the intelligence to switch

between the modes to ensure the most efficient operation. When utilizing direct free cooling, the DX system compressor stops,

which has a significant impact on the energy consumption.

In recent years, energy-efficient data centers have attracted greater attention and many data centers are now able to achieve

significant energy savings through both increasing the IT equipment tolerance temperatures and expanding the considered

geographical scope to exploit direct free cooling (which is not only limited to regions of extreme cold).

Continuous and reliable operation of the air conditioning

systems is critical for the successful operation of data

center equipment. As a result of the high proportion of

power consumed by such air conditioning systems, energy

consumption has been a challenge faced by modern data

centers. AIRSYS precision air conditioners aim to address

this challenge, in part, through effective group control

and rotation functions. Such control philosophies ensure

consistent room temperature and humidity, together with

continuous reliable operation (generally, by the addition of a

spare unit for redundancy) whilst minimizing the total power

required for the air conditioning. Group control and rotation

functions will also typically extend unit life and effectively

save energy by improving the overall management of the

system.
