Toshiba announces R32 VRF
26th July 2022
UK: Toshiba has announced the launch of its new SHRM Advance VRF air conditioning system, specifically designed to be safely used with the lower GWP A2L refrigerant R32.
It’s new flagship system, Toshiba’s SHRM Advance is said to be more efficient, more compact, and quieter than its award-winning predecessor, and delivers a significant reduction of up to 80% in CO2e emissions compared with similarly sized R410A systems.
Available in sizes from 8hp to 24hp, the new VRF can be selected for either three-pipe heat recovery or two-pipe heat pump operation. At the heart of the unit is a new liquid injection version of Toshiba’s twin-rotary compressor. In addition, the SHRM Advance incorporates a split heat exchanger, sub-cooling plate heat exchanger, a new high performance fan motor, and a special thermodynamic circuit. All these features contribute to a class-leading SEER up to 8.9 and SCOP up to 4.67.
Importantly with the use of a flammable refrigerant, safe operation is said to be a key design priority. On board is an advanced integrated leak detection with visual and audible alarms and an automatic shut-off valve system. The R32 refrigerant charge is also low at just 6kg to 9kg across the range.
To ensure regulatory compliance at the design stage, Toshiba’s equipment selection software takes account of mandatory requirements, based on floor area and refrigerant quantity. For each proposed project design, it gives installers and consultants full guidance to ensure regulatory compliance and ensure total peace-of-mind.
For system designers, a new generation of innovative flow selectors with up to 12 ports gives enhanced flexibility and optimises the ability of SHRM Advance to deliver simultaneous cooling and heating.
A new compact chassis height of just 1.69m helps integration on site, while it is possible to connect up to 69 indoor units per system. A completely new range of 107 indoor units in 13 different types are available, in sizes from 0.3 to 10hp.
As well as conventional indoor units, SHRM Advance is available with a fresh air ventilation duct and a medium temperature water module. Supported by a 70-200% diversity ratio, full system customisation is possible to overcome site-specific project constraints.
For applications requiring enhanced levels of indoor air quality, Toshiba’s one-way and four-way cassettes offer plasma/ionizer air purification, while the high-wall unit has an ultra-pure filter.
Control is enhanced by Toshiba’s TU2C-LINK communication system, giving improved speed and connectivity. A full line-up of wired and central remote controllers is available, offering full compatibility with the new R32 safety devices.
Monitoring solutions include the Wave Tool Advance (available from App store and Google Play) and Link Adaptor, enabling quick and easy servicing.
The launch will be rolled out across Europe in the coming weeks with production due to start in August/September.
“With the race to achieve net-zero, building owners and operators are under increasing pressure to minimise their carbon footprint,” said David McSherry, head of Toshiba DX, residential and light commercial, TCUK. “In addition to the significant sustainability benefits, as the price of R410A rises and availability falls, R32 offers a very attractive optimum alternative, with significantly lower GWP, reduced costs and improved energy efficiency. SHRM Advance represents a win-win for customers and the environment.”
