Toshiba SHRM-e Heat Recovery System Review

The Toshiba SHRM-e is a next-generation heat-recovery VRF system designed for maximum flexibility and environmental performance.

It provides simultaneous heating and cooling through a highly efficient three-pipe circuit, making it ideal for multi-zone offices, hotels, hospitals, and mixed-use buildings across the UK.

System Overview

SHRM-e uses triple inverter compressors, variable refrigerant temperature control, and precision electronic expansion valves.
It can connect up to 64 indoor units with a total piping length of 1 000 m and vertical separation up to 90 m — perfect for high-rise projects.

Performance and Efficiency

• SEER: 8.6

• SCOP: 5.2

• Energy Class: A+++

• Heating Range: –25 °C to +24 °C

• Cooling Range: –10 °C to +52 °C

Toshiba’s Intelligent Flow Control redirects recovered heat between zones, achieving energy savings of up to 50 % versus two-pipe systems.
All units operate with R32 refrigerant, reducing GWP by 68 %.

Smart Control and Integration

The system connects easily to BMS platforms (BACnet, Modbus, LonWorks) and Toshiba’s Wave Tool App for real-time commissioning.
Cloud monitoring enables remote fault diagnostics and energy reporting for multi-site installations.

Acoustic and Operational Comfort

Outdoor noise levels start from 48 dB(A) and indoor units operate as low as 23 dB(A).
Variable fan speed and low-pressure refrigerant control ensure smooth, quiet operation under any load.

Reliability and Maintenance

Self-diagnostic software logs every system parameter.
Dual backup compressors guarantee operation continuity if one module requires service.
Maintenance intervals extend to 5 000 operating hours.

Environmental Compliance

All components comply with F-Gas and EcoDesign ERP Directive.
Recovered heat can be used for domestic hot water production, further enhancing building sustainability.

Conclusion

The Toshiba SHRM-e redefines VRF efficiency with its heat-recovery architecture and smart digital controls.
It delivers consistent comfort while meeting strict UK sustainability targets — a true future-ready HVAC solution for large-scale buildings.
