Toshiba mini VRF on R32

UK: Toshiba Air Conditioning is expanding its portfolio with a mini VRF system for small commercial applications using R32 refrigerant –  its first VRF to be manufactured in Europe.

The new-generation R32 MiNi-SMMS VRF operates with a reduced refrigerant charge, said to achieve an 80% drop in CO2 equivalent emissions compared to the previous models.

The use of twin rotary compressors, inverters and intelligent VRF control have helped the product achieve SEERs close to 10 and SCOP up to 5.2. 

The single-fan chassis models, which cover 4 to 6hp in capacity, measures just 1050mm high and weighs only 100kg to ease product handling and integration for installers. 

The new MiNi-SMMS offers a wide temperature operating range from -20°C for heating and up to +46°C for cooling, optimised by as-needed defrosting function and new wired remote control featuring Bluetooth connectivity. 

Eleven types of indoor unit are available from 0.3hp to 5hp, a number of which feature advanced air filtration solutions for projects that require high indoor air quality. 

The indoor unit achieves sound levels of 23dB(A), while the outdoor unit can achieve 52dB(A) at maximum operating level, which users can reduce to minimum 44dB(A) in night mode if required. 

Pipe runs are up to 300m in length and up to 50m in height between outdoor and indoor units, while 20Pa available static pressure further contributes to flexible integration of the outdoor unit. 

Safety devices include leak detectors, shut-off valves and a battery kit in the event of a blown fuse.
