Toshiba SMMSe – 2 pipe heat pump | Super Modular Multi System
Expanded installation flexibility
The compact design of the outdoor units gives increased performance that defies their compact module size. This delivers greater freedom in layout design and minimises weight-related restrictions and allows for quicker installation.
- Very compact design with reduced footprint
- Capacity up to 56kW (20HP) can be covered with a single module, reducing pipe work and overall installation time
- Expanding the maximum combination up to 157kW (56HP) in one system, with up to 64 connectable indoor units
- Maximum piping length of 1,000 metres, farthest equivalent length 235 metres
- Maximum vertical distance between indoor units, which reaches up to 40 metres, equal to an entire 11-story building
Key features
Energy saving
Adopting the highly efficient DC twin-rotary compressors with various technologies realised over 7.00 ESEER for all capacity range.
ESEER Test condition
- Indoor temperature: 27ºC DB/19ºC WB
- Outdoor temperature: 100% 35ºC DB, 50% 25ºC DB, 25% 20ºC DB
- ) ESEER formula: EER at 35ºC DB * 0.03 + EER at 30ºC DB * 0.33 + EER at 25ºC DB * 0.41 + EER at 20ºC DB *0.23
Expansion capacity range
Outdoor units improve performance to achieve greater space efficiency that defies their compact module size to deliver greater freedom in layout design. This also minimises weight-related restrictions and allows for quicker installation.
Rotational control
The rotational control in SMMSe is designed to improve system reliability by controlling the operation of each compressor to work equally under variable conditions.
Key technologies
DC twin-rotary compressor
The Toshiba DC Twin Rotary Compressor is compact and reliable with a wide operating range. It utilises two rollers rotating together making accurate compressor rotation possible, and the low oil release method combines to deliver higher performance efficiencies and peaceful operation. DLC-coated dual vane reduces friction due to increased hardness and high adhesion of the material.
2 Heat exchanger
Toshiba’s 3-row heat exchanger design, with reduced pipe size from 8mm to 7mm and the increased total number of passes, improves both system performance and efficiency.
While the 3-row heat exchanger design allows the outdoor unit to automatically select the most suitable heat exchanger size and precisely matching the indoor capacity load, its 4-sided design ensures the maximum possible flow rate across the entire coil, improving system efficiency.
Propeller fan
Toshiba’s bat wing fan design increases the delivery of air volume while the anti-eddy ribs and rubber sealing rings work in harmony to reduce air resistance thus achieving quieter operation.
Inteligent VRF control
The advanced intelligent VRF control continually adjusts the operation of both indoor and outdoor units, based on the feedback from multiple sensors. While the refrigerant flow to each indoor unit is precisely controlled by the outdoor unit ensuring a more even capacity distribution throughout the system. Plus the evaporative and condensing temperature is automatically adjusted to maintain optimum indoor room temperature, regardless of the unit’s load or its physical distance from the outdoor unit.
