1 Indirect Air-cooling Unit G1--21b

2 is an air-cooling system that cools in introduce outside air directly into indoor areas. By taking advantage of outside air energy all throughout the year, F-COOL O operations compared with the use of general air conditioners. Possible carbon dioxide reductions and energy savings throughout the year Coefficient of performance (COP* 1 ) =1 (annual average in Tokyo) Possible reduction in electricity charges is about 123 million UD per year Possible reduction in carbon dioxide is about 36 tons per year About 6% savings in energy compared with general air conditioners* 2 Cooling capacity: 4 k, upply air (A) temperature: 26 C, upply air (A) flow rate: 8 m 3 /h, : Monthly mean temperature of Tokyo. Carbon dioxide basic unit* 3 :. kg CO2/kh otes: *1: Coefficient of Performance = Cooling capacity (k) / Power consumption of air conditioner (k). The larger the COP, is the better the efficiency. *2: Assuming that COP = 3. for a general air conditioner. *3: Alternative values of the actual emission coefficients for each electric utility company in FY2 as announced by the Ministry of the nvironment, Goverment of Japan. Indirect outdoor air cooling operates without introducing outside air directly so there is no need for concern about the indoor areas being contaminated from the outside such as by dust (PM 2.), Ox, or Ox. Internal tructure Diagram The indirect outside that drives the sensible heat exchanger and the refrigeration that is driven by the compressor are integrated in the unit.

6 ith the, the heat source equipment air-conditioning systems is no longer required. ven when compared to outside air direct air-conditioning systems the F COOL Comparison with an Air-Conditioning ystem Using 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. ince 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.

8 Redundant Operation and Maintenance As an optional function, it is possible to start or stop the F-COOL O, and set the supply air (A) temperature and air flow rate by means of a higher-level building management system. (Option) In order to ensure the reliability required of data center facilities, we recommend operating with +1 redundancy (for a TIR 2* data center) or +1 or more redundancy (for a TIR 3 & 4* data center). +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, 4 k) to be used, where is the total number of units required, +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. *: tandards for Data Center from AI/TIA-42-A-212.
