Our company strengthened the product lineup of commercial use air conditioners including multi air conditioning system "AIRSTAGE®" J-ⅢL series realizing the industry’s smallest outdoor unit (1,428mm H x 1,080mm W x 480mm D) for expanding the business of air conditioners for small scale stores and offices in Europe. For small stores and offices in Europe, there are many places where installation of facility equipment is restricted to preserve the landscape, and it is required to install outdoor units utilizing narrow space such as gaps or balcony of buildings. In the "AIRSTAGE®" J-ⅢL series, the cabinet structure of outdoor unit was reviewed and the industry’s smallest compact indoor unit was realized. Also, the top class low sound operation was realized by reviewing the fan shape of outdoor unit and the amount of refrigerant used was reduced by optimizing the structure of heat exchanger. In addition, the multi air conditioning system (8/10 HP) with outdoor unit of the same size as J-ⅢL operating 4 indoor units simultaneously and the large size duct single air conditioners (8/10 HP) in which indoor units can be carried in a divided manner were added to the lineup to respond to various needs according to the usage form of building. Features Common features Greater energy efficiency Energy-saving functions Greater comfort Design flexibility High reliability Easy Installation Easy service and maintenance Series features Compact design Advanced technologies for high efficiency Long piping length Up to 30 indoor units can be connected High static pressure Best-in-class low-noise operation Outdoor unit lineup System overview Compact outdoor unit The compact outdoor unit is designed to operate quietly and can be installed in a regulated environment or in tight spaces such as in an equipment room or on the rooftop. Small-room application The optimum heat exchanger structure allows up to 30 indoor units to be connected to an outdoor unit. Ideal for use in a building with many small rooms. Quiet operation The outdoor unit achieves best-in-class low-noise operation. It can be installed without erecting an acoustic barrier around it. Compact design The outdoor units in this series are much more compact than conventional outdoor units with comparable capacity. They can be installed in places out of public sight or on the roof. Advanced technologies for high efficiency Large propeller fan A large-diameter propeller fan with our proprietary blade design reduces draft loss, which results in highly efficient, low noise operation. DC fan motor A small, multi-stage DC fan motor contributes to highly efficient, low noise operation. Large heat exchanger The use of a large 2-row heat exchanger substantially improves heat-exchanging performance. DC inverter control The use of a new active filter module improves efficiency. Subcooling heat exchanger The use of a dual-tube heat exchanger improves cooling performance. Scroll compressor The combination of a scroll compressor with a wide rotational frequency range from 15 to 120 rps and our proprietary sensorless sine-wave control that smoothly controls the input power into the motor achieves more energy-efficient and quieter operation. Long piping length Our advanced refrigerant control technology extends the maximum allowable length of refrigerant piping to 400 m. This provides greater flexibility in system design. Up to 30 indoor units can be connected The combination of smaller but sufficiently powerful indoor units and a new outdoor unit with an optimized heat exchanging structure makes it possible to connect up to 30 indoor units, which is best in its class. The maximum allowable piping length extends to 400 m to accommodate various room layouts. * Only when new indoor units and the outdoor unit of the J-IIIL Series are connected High static pressure External static pressure measures up to 30 Pa (only on the 12-HP model). Best-in-class low-noise operation The outdoor units in this series are designed to operate extremely quietly. They are an ideal choice for installation in densely populated areas.
