Develop an air -cooled package air conditioner that solves air conditioning issues in the Hyper Scale Data Center

Hitachi Johnson Controls Air Conditions Co., Ltd. (Headquarters: Minato -ku, Tokyo) has recently developed a “Hitachi Package Air Conditioner Exclusive Type (for Information Communication) High Efficiency Type (1220)”, which greatly improves energy saving., Shipping will start on July 15, 2022.This product is an air -cooled package air conditioner with a compact housing with high energy saving and heat -consuming capacity, and contributing to the problem solving of the high -scale data center in the high -scale data center of 8 kva per rack.

[Background of development] The vast amount of data processing that continues to grow with the progress of the information society tends to be consolidated in large -scale data centers by the cloud. The Proposal of the National R & D Corporation Science and Technology Promotion Agency for the Low Carbon Social Strategy Center (2021)*is estimated to be 14 TWh of annual power consumption of data centers in Japan, and the other annual power consumption is about 5 TWh. 。 Air -conditioning energy saving can greatly contribute to reducing energy consumption in data centers. In addition, the data center excretes heat from ICT devices, but since ICT equipment is vulnerable to heat, it is necessary to cool down to prevent server failures and malfunctions. This product has a feature that contributes to the solution of these issues in the data center. * Technology to realize a low -carbon society and proposal for the proposal for innovation policy based on the quantitative economic and society scenarios, the progress of society on energy consumption (VOL).2）－データセンター消費エネルギーの現状と将来予測および技術的課題－2021年2月国立研究開発法人科学技術振興機構　低炭素社会戦略センター 【本製品の主な特長】高い省エネ性・サーバー類の消費電力の次に、消費電力が大きいのが空調です。本製品は年間COP4.80以上*1を達成しました。・サーバーの熱負荷（顕熱能力比率）に合わせて風量がコントロールでき、さらなる省エネ化が図れます。コンパクト筐体で高い顕熱能力室内ユニットの設置面積は1.Despite being 93 square meters, the heating capacity per area hits is 63..Demonstrate 2kw/㎡*2.

* 1 Ashrae Standard 90.4-2019 Conditions: ・ Ability 110.5kW/air volume 500m3/min (△ T11DEG) ・ Outside air follows EA2000 ・ Room temperature 29 ° C

* 2 Indoor sucked air dry spherical temperature 35 ° C, wetball temperature 20 ° C, outdoor sucked air dry spherical temperature 35 ° C, refrigerant piping is horizontal one way 7..5m

壁吹出方式に対応床下吹出方式はもちろん、壁吹出方式にも対応しています。

停復電特性、ＵＰＳ（ 無停電電源装置）対応の向上停電後の空調機の回復時間を当社現行機種より短縮しました。室内送風機は復電後約３秒で起動、圧縮機は復電後約40秒で定格周波数まで回復します。 その他・空冷パッケージ式のため、水槽設備や水配管の工事が不要。また水の凍結防止処理などのメンテナンスコストを低減します。・室外機の機外静圧を0、30、60、80Paより現地で設定が可能。・最大配管実長160m、高低差90mまで対応可能など、高い設計自由度。・高室温に対応。(停復電等の使用状況により一時的に室内温度が上昇する場合に限り、室内吸込温度50℃DB（室外35℃）まで運転可能)・BACnetに接続が可能。
