ENERGY – Advanced Technology Electronic Expansion Valve Modulation 0 -100% of refrigerant flow High regulation quality Quickly reaching of stable conditions and reaction to external variations 51

ENERGY – Advanced Technology Electronic Expansion Valve The wide range of functionality with different pressure gaps, together with the fine regulation, allows a reduction of the consumptions between the 20% (annual average) and 30% (seasonal peaks) 52

ENERGY – Advanced Technology Electronic Expansion Valve 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 60

PRELIMINARY CHOICES The whole INNOV@ range in DX system is now equipped with the advance control : p. CO 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 • • F 407 : R 407 C with Thermostatic expansion valve EV 07 : R 407 C with electronic expansion valve • • F 410 : R 410 A with Thermostatic expansion valve EV 10 : R 410 A with electronic expansion valve For Chilled water units You must pay attention to the valve type • 3 WVM : Modulating 3 -way valve 0 -10 V • 2 WVM : Modulating 2 -way valve 0 -10 V 66

CONDENSING PRESSURE CONTROL 78

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 (FSC 1, FSC 2, FSC 3) 3 control possibilities according to the unit and type of condenser(s) This option is available on-board or stand-alone (CCSxx) FSC 1 FSC 3 FSC 2 NOTA : Standard for INNOV@Energy 80

CONDENSING PRESSURE CONTROL Water-condensed Units: Water-Saving Valve (P 2 WV) 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 -30°C < Text < -15°C 82
