TR2-W-G04-Z is the result of Mitsubishi Electric Hydronics & IT Cooling Systems’ extensive approach to sustainability. Achieving outstanding performance and ensuring long-term sustainability are challenges that modern HVAC systems need to tackle. Increasing concerns about the global warming impact of chillers and heat pumps is driving new

Combining brilliant annual efficiency with the use of a low GWP refrigerant, TR2-W-G04-Z tackles both the indirect (due to the primary energy consumption) and the direct global warming impact, thus resulting in the perfect choice for any new, forward-looking cooling system. The environmental impact of the refrigerants is measured by two parameters:

TECHNOLOGICAL CHOICES Negligible inrush current, quiet operation, unrivalled efficiency and extreme flexibility comes from a definite choice: cutting-edge technologies. Comprehensive refrigerant leak detection solutions TR2-W-G04-Z can be equipped with several leak detection systems that will promptly detect any leakage: 4Internal refrigerant leak detector 4Leak detection + migration 4Leak detection with compressor off The detector has a double-threshold and can deactivate the compressors and disconnect the exchangers.

Innovative exchanger couples The expertise makes the difference The excellent performance of oil-free centrifugal compressors are enhanced by pairing them with specifically designed (flooded evaporator and shell and tube condenser) to ensure the most minimal approach between the refrigerant phase changing and the water. This provides an increased cooling capacity and reduces the the compressor load, with immediate benefits to overall efficiency.

Centrifugal oil-free compressor

Specially designed for HFO

These top-level compressors bring enormous benefits in terms of efficiency, adjustments, vibrations, and weight. Magnetic levitation eliminates the need for lubricant, with its delicate management and heat exchange loss. Soft start, integrated in the compressors, lowers the inrush current to only 2 Amps, making the selection of power line systems more favourable. Thorough knowlegde is necessary to harness such a concentration of technology and here is where the RC brand really makes the difference thanks to its 15-year experience in magnetic levitation compressor units and thousands of projects all over the world.

Acoustic enclosure The already minimal noise emissions of TR2-W-G04-Z units can be further reduced by choosing the acoustic enclosure option, available in two versions:

Basic -14 dB(A) Plus -18 dB(A)

Compact electric panel Thanks to its careful design, the electric panel can host a number of options, without altering the dimensions of the unit: 4Smart current limit 4Signals to control the water flow in both exchangers 4Lights on electric board + socket 4 Compressors run status device There are many other options for customizing the units according to your needs.

Have the unit running at full load in a shorter time

All unit in standard working conditions delivers 100% of cooling capacity within 180” after power is restored. Fast restart - UPS excluded (STD) It requires an external 230V AC UPS, not supplied with the unit, to keep the on-board controller functional and ensure fast restart after a power outage.

Fast restart - UPS included (Opt. 4502) This option includes an electric device capable of keeping the controller power supply uninterrupted during a power failure. The capacity of this device is selected on the basis of the needs of a specific project.

DOUBLE POWER SUPPLY TR2-W-G04-Z can be connected to two separate power lines to enhance the system’s dependability. Main Line

In case of a main line power outage, the ATS* automatically switches over to the backup line, granting uninterrupted power supply to the unit.

Generator

The double power supply makes TR2-W-G04-Z suitable for Uptime Institute’s TIER III and TIER IV** design topologies, the highest standards of reliability.

* ATS: Automatic Transfer Switch ** The Tier Classification System provides the data center industry with a consistent method to compare typically unique facilities based on expected site infrastructure performance, or uptime.

Double power supply (ATS) (Opt. 1561) The ATS, installed within the electrical board, automatically senses if one of the sources has lost or gained power. The switching is completely automatic (line priority and frequency of checking are selectable).

ENERGY METER You can’t manage what you don’t measure. PUE (Power usage effectiveness) is the ratio that determines how energy efficient data centers. Thermal energy meter Acquires water temperature and flow ratio delivered by the unit and compute the cooling capacity produced. together with energy meter you can instantanously evaluate the EER.

SOLUTION

OS-IX data center is owned by Bulk Infrastructure and Akershus Energi. The OS-IX complex has a total area of 25,000 m², which makes it the largest data center in Oslo. OS-IX is a connectivity hub for the national and international fiber grid to ensure redundancy.

Bulk Infrastructure and Akershus Energi decided to revitalize the building with new infrastructure with the aim of becoming the most competitive data center location in Oslo, both in terms of cost effectiveness and in terms of achieving low PUE (Power Usage Effectiveness).

When it came time to choose the IT cooling solution, a system based on RC units was selected. X TYPE T2 S close control air conditioners were chosen for the data halls, NEXT EVO Inv DW for the UPS/Battery rooms, NEXT EVO CW for the two MMR and carrier rooms, and UNICO TURBO air cooled chillers with free-cooling, designed for cooling capacity of 3,200 kW for the overall building. A solution of this kind, offers the lowest possible LCC and PUE and 100% free-cooling up to ambient temperature 16°C. Since the average year around temperature in Oslo is between -6 and 22°C, there is free-cooling 365 days a year.
