With the, the heat source equipment needed for generalair-conditioning systems is no longer required. Even when compared to outside air direct air-conditioning systems the F‒COOL NEO is a simple system that makes energy-saving operations possible.Comparison with an Air-Conditioning System Using Outside AirExamples of Applications Theprocess of mixing outside air and exhaust air that is required by a direct outside air air-conditioning system is not required, andthe control of humidity is easy (because there are no abrupt changes in humidity). In addition, since the mixing chamber used for themixing 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-conditioningsystem are not required, energy-saving operations are possible all throughout the year. Insuch fields that require air conditioned cooling with clean air throughout the entire year, from data centers to precision machining, andfoods to pharmaceuticals, F– COOL NEO is the perfect air conditioning system.Building-Type Data Center Direct Outside Air System (Utilize outside air)Indirect outside air-cooling unit Server roomDirect outside air-cooling unitExhaust airServer roomExhaust air ServerServerRefrigeratorOutside airServer roomOutside airExamples of installation for a building-type data center and the flow of airOutside air filter(Dust, salt damage)Humidifier(for indoor humidifier control)Integrated TypeSeparate TypeModular-Type Data CenterContainer-Type Data CenterIndirect outside cooling unitRefrigeratorComparison of Air-Conditioning Systems Amongthe air-conditioning systems that use outside air, an outside air indirect air-conditioning system (F-COOL NEO) is the best.Centrifugal chiller Air handling unit systemAir-cooled packaged unit(PU) systemIndirect outside air air-conditioning system (F-COOL NEO)Integrated typeSeparate typeIndoor unitCOPUse of outside air energyRisk of water supply outage,water freezingMaintenanceSpaceWorkabilityImplementation in stages Outdoor unit Symbol legend: Best, Good, Fair, Not good56
