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 well-known 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.
ENERGY – Advanced Technology
Inverter Technology: brushless motor
54
1. Direct expansion + variable speed → better EER in partial load.2. Compressor never stops → increasing in reliability3. Stepless modulation → precise Temperature control4. 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
ENERGY – Advanced Technology
Inverter Technology: brushless motor
55
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
ENERGY – Advanced Technology
Inverter Technology: brushless motor
56
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
• 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;
Synchronous motors

Rotor
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• the electronic device makes the stator magnetic field follow the rotor
one synchronously
ENERGY – Advanced Technology
Inverter Technology: brushless motor
58
PROS of the BLDC motor on the asynchronous motor:
• 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
59
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
For DX unitsYou 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 unitsYou must pay attention to the valve type
• 3WVM : Modulating 3-way valve 0-10V • 2WVM : Modulating 2-way valve 0-10V

CONDENSING PRESSURE CONTROLAir-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.
Input is the discharge pressure which is detected by a pressure sensor.

This option is available on-board or stand-alone (CCSxx)
NOTA : Standard for INNOV@Energy
80
CONDENSING PRESSURE CONTROLWater-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 CONTROLAir/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).
