TOSHIBA ' S NEW GENERATION R-32 VRF SYSTEM HELPS DECARBONISE COMMERCIAL BUILDINGS AND REDUCE RUNNING COSTS
Safe operation is a key design priority and is ensured by an advanced integrated leak detection and shut-off valve system .
A full range of 13 different types of indoor unit are available , from 0.3 to 10HP capacity .
The latest generation of Toshiba ’ s flagship Variable Refrigerant Flow ( VRF ) system , SHRM Advance , operates on lower Global Warming Potential ( GWP ) R-32 refrigerant . The combination of R-32 ’ s lower GWP and reduced refrigerant charge enables SHRM Advance to deliver a significant reduction of up to 80 %* in equivalent carbon emissions .
This all-new system gives end-users an ultra-efficient , high-quality cooling and heating solution , enabling office buildings , large shops and restaurants , healthcare facilities and educational establishments to achieve best-in-class sustainability credentials , while reducing running costs .
David McSherry , Head of Toshiba DX , Residential and Light Commercial , TCUK , said : " In addition to the significant sustainability benefits , as the price of R-410A – the refrigerant used in VRF systems to date – rises and availability falls , R-32 offers a very attractive optimum alternative , with significantly lower GWP , reduced costs and improved energy efficiency . SHRM Advance represents a winwin for customers and the environment ."
For installers , the fully packaged SHRM Advance is available in 8 to 24HP capacity units , giving flexibility to meet the needs of any commercial building project . 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 . Supported by system loading of up to 200 % with indoor units available from 0.3 to 10HP capacity .
As well as conventional indoor units , SHRM Advance is available with a fresh air ventilation duct and a medium temperature water module . For 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 .
Safe operation is a key design priority and is ensured by an advanced integrated leak detection and shut-off valve system .

The new system incorporates technical innovations including the ability to select either three-pipe heat recovery or two-pipe heat pump operation , a new twinrotary compressor with liquid injection , split heat exchanger , sub-cooling plate heat exchanger , a new high performance fan motor , and a unique thermodynamic circuit , all contributing to class-leading efficiency of SEER up to 8.9 and SCOP up to 4.67 .
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 . An advanced heat recovery function provides heat to the indoor unit with minimal input from the condensing unit , further improving energy efficiency and helping to minimise carbon footprint .
* Compared with similarly sized R-410A systems . The precise percentage will depend on the system design for each installation .
