Toshiba has launched the next generation of its 2 pipe heat pump solution, the Super Modular Multi System (SMMSe).
The SMMSe continues to push forward technological boundaries, giving significant improvements to capacity, footprint and energy saving. The new models boast a long list of clever innovations, comfortably placing Toshiba at the forefront of the VRF market.
According to John Caione, business unit manager of Toshiba Air Conditioning, it is Toshiba’s latest and greatest VRF system to date.
“It embodies developments in three core technologies - the compressor, heat exchanger and advanced intelligent control - combining to extend efficiency to unprecedented levels and a notably reduced product footprint,” he said.
“The new compact, yet powerful units provide a capacity of 56kW in a single module and maximum of up to 157kW in one system.
“A significant reduction in footprint compared to the previous system contributes to easier expansion and more flexible installation.”
Toshiba has made substantial advances in key technologies for the new SMMSe, including improvements to its patented compressor, sophisticated rotational control and high efficiency heat exchanger.
This has led to the SMMSe being awarded the ACR Product of the Year, ahead of the industry with the ESEER at over 7.0 for the overall capacity range, demonstrating excellence in efficiency.
Toshiba’s DC twin-rotary compressors use a two-stage compression method and operate in a wider range of rotation speeds for superior performance. The new vanes are coated with Diamond-Like Carbon (DLC), providing remarkable hardness, wear resistance and reliability.
The new compressors offer a displacement volume 50 per cent higher than their previous generation VRF system.
Improvements to the SMMSe advanced rotational control significantly broaden the thermal operating limits of the system: From minus 5 to 46 degrees Celsius in cooling mode.
Toshiba’s expertise in VRF research and development has led to the redesigned variable heat exchanger. This allows the outdoor unit to adjust its heat exchange performance to suit the required capacity load from 100 per cent to 20 per cent, without compromising efficiency.
A newly developed piping design enables piping to reach up to 1,000m in length while supporting a maximum distance between the outdoor unit and the farthest indoor unit of up to 235m.
This increased flexibility is especially convenient for apartments, hotels and office installation layouts, as the new design allows a distance of up to 90m between the first and the last indoor modules.
Finally, in addition to offering a significantly smaller footprint with compact, highly cost-effective units, Toshiba’s SMMSe delivers peace of mind with a backup operation providing continuity of activity. This feature allows the system to operate if a compressor fails to function.
“We believe the SMMSe takes VRF efficiency another quantum leap forward, and is set to be a winner,” Calone said.
