Toshiba’s new triple rotary compressor pushes VRF boundaries Volume 7 No.4 At the heart of Toshiba’s latest VRF, the SMMS-u is a ground-breaking new triple rotary compressor developed in-house, which significantly improves energy e ciency and overall reliability. And with a refrigerant pre-charge almost 50 per cent less than the previous model, it also o ers significant safety and environmental benefits. In recognition of its e ciency, the Japanese government-backed Energy Conservation Centre has awarded SMMS-u the country’s highest technology award for innovation in this product and business segment. Volumetric efficiency One of the keys to the new compressor’s e ciency is its new multi-port design, which results in a significant reduction in pressure losses within the system. The previous generation of two-stage rotary compressors had just two ports; the new Toshiba triple unit has six.
