1 Set Free Modular FSXN Engineering for tomorrow. And the tomorrow after that.

2 0 0 Introducing a new addition to Hitachi s Set Free range of VRF air conditioning units - enhancing efficiency and user experience Hitachi air conditioning successfully meets installer and customer demands offering greater functionality, control and cost savings There is increasing demand for a holistic approach to air conditioning in modern offices units that are capable of simultaneously cooling and heating, adapting to the different seasons and various temperature requirements of rooms. Customers also want to save time, money and space with their air conditioning and have the flexibility to extend or modify their air conditioning set-up to suit changing needs. And of course there is a growing demand for air conditioning to be as environmentally friendly as possible enabled through an air-conditioning management system that makes it easier for users to have simple, effective control of their air conditioning units to avoid unnecessary energy wastage, including overheating, overcooling and unattended operation. To meet and exceed these important requirements, Hitachi has developed the Set Free FSXN air conditioning system. Needs of end user Heat recovery operation Energy efficient Greater user control Flexibility to extend system Needs of consultants Time saving with equipment layout design Flexible, modular system designs Intelligent controls Needs of contractor and installer Modular and lightweight for quicker (or phased) installations Increased piping lengths for flexibility Set Free FSXN Capable of heat recovery and -pipe heat pump operations Set Free FSXN benefits Compatible with Hitachi s system free indoor units and heat recovery ventilation units Hitachi s outdoor units feature a heat recovery operation system as well as a -pipe heat pump operation system. This avoids the need for review work when designing the equipment layout, while reducing the workload and time spent installing the units on site. Wide product range - All models (8 to 54HP) When used as a heat recovery operation system Set Free FSXN (Module Type) When used as a -pipe heat pump operation system Energy saving - Heat recovery and DC Inverter Driven Flexibility of installation - Compact and lightweight design and flexible refrigerant piping Comfort and reliability - Capable of impressively low noise levels with noise reduction preference mode (option) Control by Network System Off coil temperature control CH units pipes Heat Recovery and -pipe heat pump operations Common Unit 8 to 54HP 4 models (Outdoor unit: 6 models) The heat recovery and -pipe heat pump operation systems cannot be switched over after installation is complete. pipes

3 04 05 Heat recovery operation Heat recovery operation - the most important requirement Heat recovery operation system - meeting different air conditioning needs in the same building Temperature control in today s modern spaces is vitally important. There s increasing customer demand for the need to switch between cooling and heating, depending on time of day and external environmental conditions. And of course, equipment such as computers and terminal devices can also add to the heat in spaces. Therefore, heat recovery operation is often a top priority when considering air conditioning systems for buildings. To meet these needs, Hitachi has developed the Set Free FSXN, offering effective heat recovery operation. ased on our existing heat recovery operation system Set Free FXN - we have expanded the range; enhancing efficiency, reducing the dimensions and improving workability. As a result, Set Free FSXN offers superb energy-saving efficiency and better comfort. In office buildings The heat inside buildings is less likely to be released due to improvements in building structures, such as heat insulator performance and doubleglazed windows. Cooling is required throughout the year where there are lighting fixtures and IT equipment; equally other areas can be affected by ambient temperatures and sunshine, so either cooling or heating is required according to changes in the flow of heat. Compensate and adjust when there are hot and cold rooms in the same building, depending on the direction of sunshine. In commercial buildings Meeting Room Offices Control the air temperature separately from room to room because of different heating/ cooling requirements. Heat recovery operation is essential in commercial buildings where, for example, restaurants and shops co-exist. Handle changes in airconditioning needs (differences in cooling/heating requirements) due to changing tenants or the alteration of partitions. Restaurant Retail Manage rooms that need to be cooled all through the year. Reduce annual power consumption. In hotels Room temperatures should be set independently according to the personal preferences of the guests, with different requirements in the open public areas. Reception Guest Room

Refer to the technical manual for more details.

8 4 5 Other advanced technologies Rotational operation* to distribute load of outdoor units Regulating the operation time of each outdoor unit leads to load reduction on compressors**. During multiple unit operation, the same rotation frequency of inverter compressor results in an equivalent load on each compressor. Therefore, outdoor unit endurance is improved.

Emergency backup operation function The backup operation function prevents the system from coming to a complete stop when an outdoor unit failure occurs*. Emergency operation starts with the remote control switch after an alarm***. * At least outdoor units are required for this function. ** Emergency operation can be performed within 8 hours after unit stoppage. After 8 hours passed from unit stoppage, emergency operation can not be performed. *** Emergency operation can be performed when the specified alarm code occurs.
