We are excited to introduce CITY MULTI® N-Generation outdoor units, a big advancement in VRF systems in a smaller package.
Latest Features and Design Flexibility
The new N-Generation high-performance outdoor units deliver better energy efficiency and personalized comfort control to commercial building applications. Featuring a 30 percent smaller footprint than previous models, the units offer more design flexibility due to improvements in vertical piping limits at 295 feet (from 164 feet). Available in 6- to 32-ton capacities, the units also include a four-sided heat exchanger delivering increased heating capabilities within the reduced footprint.
Quieter than ever before, the units feature an improved compressor and fan design with five airflow settings that control the unit’s noise output. N-Generation heat recovery systems also feature new Branch Circuit (BC) controllers that allow up to 11 sub-BC controllers connected to one main BC controller, greatly increasing design possibilities. The redesigned BC controllers have reduced height and allow service access from the bottom of the unit.
“The N-Generation was developed to be a more effective and efficient heating and cooling solution for virtually any commercial application,” says Kevin Miskewicz, director, commercial product planning, Mitsubishi Electric Trane HVAC US. “With its operational and design flexibility improvements, building owners, facility managers and commercial specifiers will be pleased with the occupant comfort and energy efficiency achieved by incorporating CITY MULTI into HVAC designs.”
Energy Efficiency and Data Collection
This latest redesign is a game-changer in terms of efficiency. The combination of the new heat exchanger, compressor and fan design improve both nominal and seasonal efficiency levels by up to 27 percent over prior generations, even at part-load conditions. Flash injection compressor technology is now standard in N-Generation high-efficiency models, offering up to 78 percent of heating capacity down to -13 degrees Fahrenheit outdoor ambient temperature.
Facility managers and building owners will also be pleased to hear how the unit simplifies troubleshooting and maintenance with built-in data storage, accessible via USB that stores up to five days of operational data.
