Electronic Expansion Valve

The wide range of functionality with different
pressure gaps, together with the fine
regulation, allows a reduction of the

53
ENERGY – Advanced Technology
Inverter Technology: brushless motor
In X-Treme density environments, the operating
cooling capacity is normally much less than the design
value and “modulating” units should be used.
Chilled water / chilled fluid systems represent a wellknown solution: disadvantages are related to the high
water (fluid) volumes inside data centres.
Inverter driven compressors modulate the capacity
but without water inside the room.
Direct expansion means higher evaporating
temperatures than a chilled water / fluid system
and this has a big impact on the efficiency of the
system.
54
ENERGY – Advanced Technology
Inverter Technology: brushless motor
1. Direct expansion + variable speed → better EER in partial load.
2. Compressor never stops → increasing in reliability
3. Stepless modulation → precise Temperature control
4. Quick reaction against heat load variation [ 6 Hz/second ]
→ no overheating in case of sharp heat load increasing.
5. Low speed in partial load → Lower noise level.
ENERGY range fully integrate compressor management with air flow management, EEV
management and remote condenser management
55
ENERGY – Advanced Technology
Inverter Technology: brushless motor
TRADITIONAL UNITS:
ON/OFF partialization keeps the
evaporating temperatures low so
humidification has to be done
INVERTER TECNOLOGY:
Compressor speed reducing increases
the evaporating temperature, so
humidification doesn’t have to be done
56
ENERGY – Advanced Technology
Inverter Technology: brushless motor
Synchronous motors
the rotation velocity is:
constant does not depend on the load
it is indeed a function both of the supply frequency and of the number of triads of polar expansions
Construction
• a STATOR with three phases for the power supply. Here the
polar expansions create a rotating magnetic field, which drag
the ROTOR;
• a ROTOR, coaxial to the stator, installed in the inner part of
the motor, made of permanent magnets;
57
ENERGY – Advanced Technology
Inverter Technology: brushless motor
how does a BLDC synchronous motor work…?
• a transducer reads the position of the rotor as to the stator
• an electrical circuit give power to the stator phases
• a magnetic field is created
Stator
• the electronic device makes the stator magnetic field follow the rotor
one synchronously
Rotor
58
ENERGY – Advanced Technology
Inverter Technology: brushless motor
PROS of the BLDC motor on the asynchronous motor:
•
•
•
•
•
•
59
the rotor moves with the same velocity of the rotating magnetic field created by the power supply
frequency, independently from the load
Lower inertia of the motor (quicker acceleration/deceleration)
Smaller dimension (lighter and cheaper components)
lower noise emissions
no start-up currents
HIGHER ELECTRICAL EFFICIENCY thanks to:
•
no induction in the rotor because of permanent magnets in the rotor
•
no current losses in the rotor
ENERGY – Advanced Technology
Inverter Technology: brushless motor
The heat (coming form the stator only) is better rejected in the BLDC motors,
so the compressors can be cooled down with discharge gasses.
• the compression power input depends from
the suction gas temperature
• in standard compressors (asynchronous) the
suction side gasses are further superheated
• in BLDC motors the suction gasses are cooler
then lower compression power input

PRELIMINARY AGREEMENTS AND CHOICES
To find easily in e-Lencal the components
described in the next slides
you will see pictures and such code
(RAIU)
The code appear
when you fly above
the equipment scare
64
PRELIMINARY CHOICES
The whole INNOV@ range in DX system is now equipped with
the advance control : pCO 1 (CAREL)
For the Chilled Water version it is already selected when you start
a new selection nevertheless you can choose the pure slave
version without controller
I advise you to take always the clock card
even if you don’t use time scheduling for maintenance and service it is interesting to have time in
alarm report
65
PRELIMINARY CHOICES
For DX units
You choose the refrigerant through the expansion valve
• F407 : R407C with Thermostatic expansion valve
• EV07 : R407C with electronic expansion valve
• F410 : R410A with Thermostatic expansion valve
• EV10 : R410A with electronic expansion valve
For Chilled water units
You must pay attention to the valve type
• 3WVM : Modulating 3-way valve 0-10V
• 2WVM : Modulating 2-way valve 0-10V

CONDENSING PRESSURE CONTROL
Air-condensed Units: Modulating Fan Speed
The fan speed controller keeps the condensing pressures within prefixed
values, no matter the load the unit operates at.
At the same time power consumptions and noise levels decrease.
The fan speed controller automatically varies the fan motor speed by
changing the motors input voltage.
Dv → DTc
at T.ext < 20°C
79
Input is the discharge pressure which is detected
by a pressure sensor.
CONDENSING PRESSURE CONTROL
Modulating Fan Speed (FSC1,FSC2,FSC3)
3 control possibilities according to the unit and type of condenser(s)
This option is available on-board or stand-alone (CCSxx)

CONDENSING PRESSURE CONTROL
Water-condensed Units: Water-Saving Valve (P2WV)
If the inlet water temperature decreases, the pressostatic 2-way valve
decrease the water flow, in order to get the right condensing T and to
control the water consumption.
This device has to be selected on City Water condensed-units. (modèles Z et Q)
But also when the water
temperature down below 25°C
81
CONDENSING PRESSURE CONTROL
Air/Water-condensed Units: Flooding Systems
Temperatures below -15° and down to -30°C require a flooding device in
order to flood the condenser internal surface and get the right condensing T.
When the temperature is too low even with the minimum flow the capacity of the condenser is still too high
then to reduce the area of the condenser we flood it with refrigerant.
To manage we need adding liquid recever and valves system to control the condensing pressure and then the
liquid level.
This technology fits water and air condensed unit.
Can be on-board (FVRS water, LTDF air) or stand-alone (LTxxx).
Only Stand-alone version when Steam Humidifier
