UNIQUE ON THE MARKET: TRIPLE ROTARY COMPRESSOR

The advanced technology used within SMMS-u results in a robust and durable system. The innovations made with Toshiba triple rotary compressor delivers an even stronger and more reliable system.

 

The exclusive Toshiba Triple Rotary compressor brings outstanding performance to SMMS-u without compromising

on system reliability .

DLC Treatment

Toshiba’s Diamond Like Carbon coating technology is unique to Toshiba VRF compressors. It covers the wear surfaces on compression vanes for outstanding hardness and wear resistance, enhancingb both the compressor’s performance and durability.

Triple Rotary Compressor

The advanced technology used within SMMS-u results in a robust and durable system. The innovations made with Toshiba triple rotary compressor delivers an even stronger and more reliable system.

 

STRONG ADAPTABILITY

SMMS-u integrates new features to adapt operations to local constraints with a constant target: the alliance of comfort and energy savings.

Split heat exchanger

Heat Exchanger automatically varies depending on workload, maximising energy savings and system reliability.

Autobackup function

Automatic backup in case of combinations systems failure.

Balance oil circuit free

No oil balance pipe needed with the new lubrication technology.

Rotation drive

Smart control to automatically equalize compressor operating hours.

Demand control

Smart control to automatically equalize compressor operating hours.

COMFORT ABOVE ALL

Providing end user high level of comfort is the SMMS-u priority. In addition to a wide range of indoor units adapted to any kind of room configuration, defrost logic has also evolved to increase continuous run time, shorten defrost cycles. Toshiba is offering one of the most accurate refrigerant flow management systems.

INTELLIGENT DEFROST

SMMS-u can maximise heating capacity by improved new heating operation and defrost operation.

Individual defrost: continuous heating up to 5 hours

Kobestu

Newly developed modular defrosting system. This new control can be utilised in modular systems only. This new control utilises the advantages of the Toshiba rotary compressor, by varying the compression ratio between the two compressors in each of the outdoors to create a two-stage defrosting control. The benefits of this control can be split between decreasing the time the outdoor is in defrost and the ability to continue to supply refrigerant to the indoor units, allowing the fans to continue to run in heating operation, albeit at a reduced capacity output.

Renkey

This new control has been designed to manage the defrosting pattern for outdoors that utilises individual refrigeration systems, but in a group setup via the new Uh protocol or via a BMS system.

Utilising the new Uh protocol, the header unit is able to control all the other units to ensure the units will defrost separately, via time shift. This control ensures the building will receive a continuous heating supply, even when one system is in defrost.

INTELLIGENT VRF CONTROL

Mixing 0.1Hz compressor speed control with high precision pulse motor valve, SMMS-u delivers the right quantity of refrigerant to all indoor units in demand. The advanced intelligent VRF control continually adjusts the operation of both indoor and outdoor units, based on the feedback from multiple sensors.
