9 Design Simulator Building Information Modeling (BIM) Put the charts and pens away and design your projects on your computer with ease using the Design Simulator. Everything from selecting indoor and outdoor units, allocating controls and optional parts to designing the piping and wiring systems is made easier using the program's builtin features. Once your project is designed take advantage of the Export functions to easily get materials lists, product specifications, refrigerant calculations and more it'll even export to Word or Excel formats, and group the relevant CAD data for your project. FUJITSU GENENRAL provides the Building Information Modeling (BIM) object models and contents for our VRF system and some products to the architect, designer and contractor using Autodesk Revit technology from our Website and Autodesk Seek Website, etc. Automatically create model selection information Each unit can be automatically set by entering the required performance, type, and temperature conditions for each indoor unit and then dragging and dropping into the outdoor unit. Piping and wiring diagrams can be created automatically and it is easy to set branches, grouping, and options. 3D and 2D product data We provide 3D data that closely resemble the actual product appearance. 2D CAD design operations are supported and 2D display is also provided. The data can also be output in other formats, such as DXF and DWG, which are used by other design CAD. The additional refrigerant charging amount is automatically calculated when the pipe length is entered. It is also easy to set the remote controller groups, central controller and converters. The equipment list including the equipment information is created automatically. Output the format that matches the application Installation limitation The equipment installation limitation range is shown. Installation requirements, such as distance from the wall, is automatically displayed to make it easy to produce highly reliable layout designs. The information specific to your project can be exported in a number of industry standard file formats. Word format (rtf) Excel format (csv) Auto CAD format (DXF) 2D Data (DXF) 3D Data (RFA) Installation information Other information, such as symbols showing the airflow direction that are required for installation drawings, is built in and can be automatically reflected in 2D drawings.

19 Features All inverter compressor Flexible piping connection Large capacity DC inverter compressor Large capacity high efficient DC twin rotary compressor with excellent intermediate capability. A more flexible refrigerant piping work is possible by the use of various piping and RB Unit connections, for adjustments to the floor layout and building structure. Separation tube efficient compressor speed control Comfortable space with small room temperature changes and little energy loss is created by 0.Hz steps compressor speed control. Capacity RB Unit (Single type) RB Unit (Multi type) Max.3 or 8 indoor units 0.Hz Application Max. 8 indoor unit Single connection Group connection Individual cooling and heating Simultaneous cooling and heating Single connection & RB Unit less connection*2 Group connection Individual cooling and heating Simultaneous cooling and heating only The RB unit can be freely positioned between the first branch and the indoor unit. The maximum height difference between RB units is 5 m. *2. RB Unit is not necessary for cooling only use. Inverter frequency Flexible installation of RB unit Multiple outdoor operation control Height When multiple outdoor units are connected a sophisticated operation is performed by each compressor. Rather than running one compressor at full load and distributing refrigerant to one heat exchanger, this control method operates all compressors at part load and distributes refrigerant to all of the heat exchangers which allows for the overall system efficiency to be improved. 98 Small & slim design saves space A drain pipe is not required The control box position can be changed to meet the installation conditions Compressor Load level efficient operation Installation possible from either side for freedom of the control box efficient refrigerant flow control Larger refrigerant flow Large intake airflow Small design saves space A drain pipe is not required Simple installation series connection design 2way connection Small intake airflow EEV 36 Installation possible on the upperside for use in narrow space Fan Heat exchanger RB unit (single type) Easy to maintenance in a narrow space Inefficient operation Heat exchanger refrigerant control The heat exchanger in the outdoor unit is split into two parts (Top and Bottom). The efficiency of the heat exchanger has been improved by adopting an optimum refrigerant path control where the refrigerant is distributed more into the top heat exchanger as this is where there is a greater air flow intake. RB unit (multi type) Heat exchanger Distributor Up to 2 units can be connected in series. Maintenance can be performed from the side. Electrics box can be temporarily fixed by sliding down. Parts can be replaced easily even at narrow space in the ceiling. RB unit Ceiling Outdoor unit 37
