It is supporting the initiative with the launch of innovative new air conditioning products, such as its latest SMMS-e VRF system, increased UK stocking levels, a major expansion in worldwide production capacity, plus its roll-out of a UK network of training centres and a new global training facility.
Stock levels at the company’s Plymouth site are being increased dramatically with the addition of a further 44,000 sq ft of racking space, ensuring immediate availability across all popular ranges of Toshiba split and VRF air conditioning.
A major extension to Toshiba’s advanced Thailand factory is under way, including expansion of its world-class research and development facilities, due for completion later this year.
This includes creation of a new global Technical Training Centre, with capacity to train 150 delegates at a time, equipped with Toshiba’s full range of air conditioning and control technology. This joins Toshiba’s award-winning network of training facilities, covering the UK and Ireland, and puts the company in the forefront of air conditioning training providers.
On a corporate level, the planned growth is supported by the Building and Industrial System (BIS) group within parent United Technologies Corporation, bringing together amongst others Toshiba Air Conditioning, Carrier Air Conditioning, Chubb Fire and Security and Otis, the lift specialists.
Developments in three core technologies – the compressor, heat exchanger and advanced intelligent control – combine to ensure all outdoor units in Toshiba’s new SMMS-e VRF range have an ESEER (European Seasonally Adjusted Energy Efficiency Rating) higher than 7, an industry first.
At its heart is a new dual vane twin rotary compressor, developed and manufactured by Toshiba, which uses a two-stage compression process for improved efficiency and performance. Wear surfaces on compression vanes are treated with a high-tech Diamond-Like Carbon (DLC) coating, 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 per cent greater than for the previous generation of VRF systems. The enables a higher capacity to be obtained from a smaller compressor, with less power consumption.
The system’s heat exchanger has been completely redesigned, using smaller diameter tube arranged in three rows in the coil, compared with two rows in the previous model, resulting in a 13 per cent 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 three-way variable heat exchanger enables the VRF’s control system to automatically select the optimum setting.
In maximum, 100 per cent of heat exchange capacity is used to deliver full cooling in high outdoor ambient. In the mid-range option, 80 per cent of heat transfer capacity is employed in average outdoor temperatures. And in the lowest setting, just 20 per cent of heat exchanger capacity is used to provide gentle operation when outdoor temperatures are low.
The SMMS-e is notable in being able to provide continuous heating, with no requirement to stop during defrosts, or having to use energy to charge other components as with alternative systems. This is made possible by the use of a new hot-gas bypass control, which simultaneously defrosts outdoor heat exchanger coils, while allowing the indoor unit to continue operating in heating mode.
David Dunn, Director and General Manager of Toshiba Air Conditioning, said:
“SMMS-e is Toshiba’s latest and greatest VRF system to date. It embodies some important technical developments, not least on the compressor and controls front, which extend efficiency and the application envelope for VRF even further into new territory.
“While end users benefit from reductions in running costs and enhanced comfort conditions, installers can take advantage of the new wireless commissioning and diagnostics system, which reduces installation time and opens up new possibilities for fast data exchange – without laying a finger on a unit. We believe the SMMS-e takes VRF technology a great leap forward, and is set to be a winner.”
“Along with best in class products and people, I believe we have one of the best distributor networks in the business. We will be continuing to invest in this over the coming months and years, to ensure our award-winning technology is available in all corners and sectors of the UK and Ireland.”
