At its heart is a new rotary compressor, developed and manufactured by Toshiba, which uses a two-stage compression process for improved efficiency and performance. Contact surfaces on the compression vanes are treated with a high-tech Diamond-Like Carbon, giving outstanding hardness, wear resistance and reliability. It enables a significant increase in compressor rotation speed, resulting in a higher displacement volume up to 50% greater than for the previous generation of VRF systems. This enables a higher duty to be obtained from a smaller compressor, with less power.
The compressor features the latest generation of Toshiba’s Infinity Variable Control, with the ability to adjust the compressor’s rotational speed in near seamless 0.1Hz steps. This allows the system to respond very precisely to changes in demand, to deliver outstanding comfort while minimizing energy losses.
The system’s heat exchanger has been redesigned, using smaller diameter tube arranged in three rows in the coil, compared with two rows in the previous model, resulting in a 13% increase in surface area available for heat transfer, further improving performance and efficiency. The capacity of the new generation heat exchanger, previously fixed, can be adjusted to match the current load and ambient conditions. The new three-way variable heat exchanger enables the VRF’s control system to automatically select the optimum setting. This operation ensures the coil is not flooded with excess of refrigerant, which reduces efficiency.
On the controls front, a new approach to intelligent operation gives building occupants improved comfort and further enhances energy efficiency and reliability. SMMS-e uses Intelligent Flow Technology, based on independent Pulse Motor Valves to control the flow of refrigerant to each indoor unit. These deliver a carefully calibrated refrigerant flow to each indoor unit to create and then maintain optimum comfort conditions, utilising 3 sensors per indoor unit.
Importantly, the SMMS-e is available in a wider capacity range than ever before. On the smaller end of the scale, indoor units are now available in capacities of 1.7Kw, increasing the number of units that can be connected into a system, making it more flexible. Up the scale, outdoor units can offer up to 61.5Kw on a single module platform, due to a newly developed chassis, this reduces footprint, pipework and speeds up installation time.
With the new SMMS-e, it is now possible to connect up to 170Kw in a single system, with up to 64 connectable indoor units, beating the previous 135kw maximum by a wide margin.
Improvements in pipe work and connectivity give significant advantages in terms of system design and application. Maximum total pipe work length for SMMS-e is 1000m, double the previous allowable length, with 235m now the maximum allowable distance between an outdoor unit and the farthest indoor unit, another industry first.
