HIGH EFFICIENCY AND LOW OPERATION COSTS

INNOVATIVE COMPRESSOR TECHNOLOGY
Toshiba’s infinitely variable inverter driven control can continually adjust the operating speed of the compressors in real time. This ensures that the capacity output precisely matches end user demand.
The advantages of this control are further optimised by incorporating Toshiba’s twin rotary compressors. These enable the SHRM-e system to achieve maximum performance and class- leading ESEER values.

INFINITE VARIABLE CONTROL
This feature has been continually evolved and developed, since its inception by TOSHIBA engineers back in 2004 with the original SMMS system. The control has the ability to adjust the compressor rotational speed in a near seamless 0,1 Hz steps. This control when matched with TOSHIBA’s newest and latest Twin Rotary compressors, allows the system to respond precisely to the capacity needs of the end user, whilst minimizing energy losses.

ADVANCED HEAT EXCHANGER
Toshiba’s new 3-row heat exchanger design, with reduced pipe size from 8 mm to 7 mm and increased total number of passes, improves both system performance and efficiency. While the 3-row heat exchanger design allows the CDU to automatically select the most suitable heat exchanger size, precisely matching the indoor capacity load, its 4-sided design ensures maximum possible flow rate across the entire coil, maximising system efficiency. Total pipe surface area has increased by 13% with the 3-row heat exchanger.

INTELLIGENT FLOW TECHNOLOGY
The unique IFT control continually adjusts the operation of both indoor and outdoor units, based on the feedback from multiple sensors.
While the refrigerant flow to each indoor unit is precisely controlled by the outdoor unit, ensuring even capacity distribution throughout the system, the evaporative and condensing temperature is automatically adjusted to maintain optimum indoor room temperature, regardless of the unit’s load or its physical distance from the outdoor unit.

MAXIMUM PART LOAD AND FULL LOAD EFFICIENCIES
Thanks to Toshiba’s unique twin rotary compressor, re-designed heat exchanger and “intelligent flow” technology, the new SHRM-e achieves a ESEER of 8.17, the highest seasonal efficiency in the market.
Maximum efficiency is obtained under 50% part load conditions, under which VRF systems operate predominantly. The expert use and evolution of Toshiba’s core technologies have allowed the new SHRM-e system to achieve the highest part load COP and EER in the industry.

FLEXIBLE DESIGN AND QUICK INSTALLATION

PIPING DESIGN FLEXIBILITY
Toshiba’s piping technology makes them one of the industries leaders in system flexibility and ease of installation and with the new SHRM-e system, the level of flexibility has increased further, giving more options to the contractor and installer alike.

1 Total piping length
Applied with Toshiba’s unique and greatly improved technology, SHRM-e can reach up to 1,000 meters maximum piping length.

2 Farthest equivalent length
The maximum equivalent distance between the outdoor unit and the farthest indoor unit tops at 200 meters, a best-in-class for the industry.

3 Height between outdoor unit and indoor unit
Another industry b e s t - i n - c l a s s feature is the maximum vertical distance between the outdoor and indoor units, which can extend up to 90 meters. SHRM-e ’ s enhanced piping capabilities results in more benefits for system design and installation flexibility,
as well as lower installation costs.

4 Piping design flexibility “FS unit-FSU”
Farthest pipe from FS unit-Indoor unit 50m allowed using the Multi port FS unit.
As the SHRM-e multi-flow selector and indoor unit can be as far as 50 meters apart, the refrigerant piping can be lengthened, offering more flexibility in design to make every space both more comfortable and attractive.

MULTI-FLOW SELECTOR FOR FASTER INSTALLATION
The use of multi-flow selector units increases the design flexibility of the system, offering the same overall capacity with a reduced number of connections. For example a 4-branch multi-flow selector box requires only 14 brazing points. This allows much faster and simpler installation, while layout design is more flexible, thanks to simplified branch and branch connections. Reducing the length of the branches also allows increased capacity. This configuration is available with either group or individual remote control.

NEAR FIELD TECHNOLOGY AND WAVE TOOL, ALL YOUR DATA WITHIN REACH
With Near Field Communication (NFC), the SHRM-e is the first in the industry to allow remote monitoring of CDU operations. Using NFC technology, Read and Write data is exchanged wirelessly between the unit and a smartphone (Android 5.0 and above) for remote commissioning and operations data checking.

SOFTWARE DESIGN AIRS MAKES IT EASIER
The new “AIRS” software has been fully redesigned, with a user-friendly interface allowing novice and expert users alike to create simple, yet detailed VRF system schematics. It is highly versatile, allowing the level of detail to be tailored to suit customer requirements. The software also allows the user to specify pricing strategy and create additional interim reports, including any diagrams and schematics required. Final detailed reports can then be produced and sent to customers in PDF format or in more complex files, such as AutoCAD DXF, allowing simple integration into their existing software packages.

SUPERIOR AIR COMFORT

COOL COMFORT WITH SOFT COOLING MODE
The development of the soft cooling mode provides a new level for cool comfort. You will have the freedom to personalize the air flow intensity, angle and direction directly from the remote control and enjoy the indoor environment at the right temperature without being directly exposed to the cold draft.

OPTIMISED HEATING OPERATIONS
The SHRM-e allows continuous heating, even during external defrost operations, thanks to the new hot gas bypass control. Indoor units will now operate continually, with only a minimal reduction in capacity output. This results in an uninterrupted flow of warm air, ensuring maximum comfort to the user.

DUAL SET POINT FOR MORE PRECISION
The Dual Set Point increases the system’s energy efficiency and reduces overall running costs, with longer periods of time in thermal off mode. Heating and cooling temperatures at which the indoor unit will begin to operate can now be individually selected giving maximum flexibility to the user.

SMART AUTOMATIC TEMPERATURE CONTROL SYSTEM
The SHRM-e’s Automatic Temperature Control (ATC) system has been designed to enhance user comfort and reduce energy consumption. Each user can easily set minimum and maximum temperatures with the ATC, which automatically maintains the air at the desired temperature. Once the maximum temperature has been reached, the intelligent Dual Set Point function will tell the system to shut down and change mode to adjust the temperature to the minimum required, 
or vice versa. This enhances efficiency and reduces running costs, by extending the thermal off periods, when the unit stops between changes in heating and cooling mode.

INNOVATIVE INDIVIDUAL ON/OFF AND TEMPERATURE CONTROL
The innovative Multi-flow Selector allows smart temperature control in each space via individual remote controls. This meets users’ different temperature requirements for maximum comfort, and if rooms are empty, the unit can be switched off. This solution helps reduce energy waste, improve efficiency and save on overall costs.

EXCEPTIONAL QUALITY AND RELIABILITY

MORE DURABLE WITH LEADING TWIN ROTARY COMPRESSOR TECHNOLOGY
The advanced technology used within SHRM-e results in a robust and durable system. The innovations made with Toshiba twin rotary compressor have resulted in an even stronger and more reliable system, extending the operational life and, thus, reducing the overall maintenance costs.

OPERATING TEMPERATURE RANGE
Extensive operating temperature range of up to 46 °C in cooling mode and down to -25 °C in heating mode thanks to new compressor design and system controls.

DEDICATED OIL MANAGEMENT
The Toshiba SHRM-e oil management control constantly monitors the real-time oil level inside each of the compressors. Based on these readings, the system can initiate various system oil retrieval controls and via the dedicated oil balance line between CDUs, the system can maintain the optimum amount of oil inside each compressor at all times.

WIDE RANGE COMPRESSOR
Using new cutting-edge technology, Toshiba’s new twin rotary DC driven compressor can operate in a much wider range of rotational speed, giving increase performance, whilst maximising energy efficiencies.

DUAL VANE TECHNOLOGY FOR ENHANCED PERFORMANCE
The all new dual vane technology reduces any variances in the contact area between the vane and roller, even when the compressor is operating at very high speeds. This results in minimal compression losses inside the compressor, further optimising its performance, efficiency and reliability.

THE DIAMOND-LIKE CARBON
The new Toshiba Diamond Like Carbon Coating technology is unique to Toshiba VRF compressors. It covers the wear surfaces on compression vanes for outstanding hardness and wear resistance, enhancing both the compressor’s performance and durability and confirming Toshiba’s reputation of providing exceptional reliability.

MAXIMUM RELIABILITY WITH BACKUP OPERATION
For maximum reliability, ALL Inverter control can be adjusted to compensate for a failed compressor or header unit. In the unlikely event of a compressor failure, backup operation is available in both a single system or as a module.
This provides reassurance to the end user that the system will continue to operate whatever the circumstance.

INCREASING COMFORT LEVELS BY GETTING THE CONTROLS RIGHT
Comfort, economic efficiency and safety can be further maximised with modern control mechanisms. Whether wired or remotely controlled units, Web-based control devices or elegant touch screen systems, the important thing is to achieve the right temperature at the right time and in the right place! It’s all about balance - and we’ve got it just right.
