●F–COOL NEO is in continuous operation at Fuji Electric’s data center demonstration laboratory located in our Kawasaki factory,in Japan and it is possible to visit this facility.
●As an optional function, it is possible to start or stop the F-COOL NEO, and set the supply air (SA) temperature and air flow rate by means of a higher-level building management system. ●In order to ensure the reliability required of data center facilities, we recommend operating with N+1 redundancy (for a TIER 2* data center) or N+1 or more redundancy (for a TIER 3 & 4* data center). N+1 redundancy means, after the total necessary cooling capacity is divided by the rated cooling capacity of the type of air conditioner unit (for example, 40 kW) to be used, where N is the total number of units required, N+1 adds an additional unit to the total number to be installed as a safety margin for redundancy. ●Please perform a daily inspection according to the instruction manual that comes with the delivered product. Also in addition to this normal day-to-day inspection, we recommend a contract for periodic maintenance and inspections.

Notes:*1: Coefficient of Performance = Cooling capacity (kW) / Power consumption of air conditioner (kW). The larger the COP, is the better the efficiency.*2: Assuming that COP = 3.5 for a general air conditioner.*3: Alternative values of the actual emission coefficients for each electric utility company in FY2011 as announced by the Ministry of the Environment, Goverment of Japan.
Cooling capacity: 40 kW, Supply air (SA) temperature: 26°C, Supply air (SA) flow rate: 8500 m3/h, Outside air (OA): Monthly mean temperature of Tokyo. Carbon dioxide basic unit*3: 0.55 kg–CO2/kWh
is an air-cooling system that cools in directly without needing to introduce outside air directly into indoor areas.By taking advantage of outside air energy all throughout the year, F-COOL NEO makes possible significantly greater energy-savingoperations compared with the use of general air conditioners.
Possible carbon dioxide reductions and energysavings throughout the year●Coefficient of performance (COP*1) =10 (annual average in Tokyo)
●Possible reduction in electricity charges is about 123 million USD per year
●Possible reduction in carbon dioxide is about 36 tons per year
About 65% savings in energy compared with general air conditioners*2

●The indirect outside air cooling circuit that drives the sensible heat exchanger and the refrigeration cooling circuit that is driven by the compressor are integrated in the unit. (Integrated type 40 kW)
Indirect outdoor air cooling operates without introducing outside air directlyso there is no need for concern about the indoor areas being contaminated from the outside such as by dust (PM 2.5), SOx, or NOx.

●Among the air-conditioning systems that use outside air, an outside air indirect air-conditioning system (F-COOL NEO) is the best.
Comparison with an Air-Conditioning System Using Outside Air
●The process of mixing outside air and exhaust air that is required by a direct outside air air-conditioning system is not required, and the control of humidity is easy (because there are no abrupt changes in humidity). In addition, since the mixing chamber used for the mixing process is also unnecessary, the duct layout can be simplified. ●Since the dust removal filters and the summer-winter switchover of operations that are required by outside air direct air-conditioning system are not required, energy-saving operations are possible all throughout the year.

●F–COOL NEO is in continuous operation at Fuji Electric’s data center demonstration laboratory located in our Kawasaki factory,in Japan and it is possible to visit this facility.
●As an optional function, it is possible to start or stop the F-COOL NEO, and set the supply air (SA) temperature and air flow rate by means of a higher-level building management system. ●In order to ensure the reliability required of data center facilities, we recommend operating with N+1 redundancy (for a TIER 2* data center) or N+1 or more redundancy (for a TIER 3 & 4* data center). N+1 redundancy means, after the total necessary cooling capacity is divided by the rated cooling capacity of the type of air conditioner unit (for example, 40 kW) to be used, where N is the total number of units required, N+1 adds an additional unit to the total number to be installed as a safety margin for redundancy. ●Please perform a daily inspection according to the instruction manual that comes with the delivered product. Also in addition to this normal day-to-day inspection, we recommend a contract for periodic maintenance and inspections.
