近日,兩家日本龍頭企業聲稱已開發出一種使用新的HFO制冷劑的數據中心冷卻系統,該系統可將功耗降低一半。
Two leading Japanese corporations claim to have developed a data centre cooling system, using a new HFO refrigerant, that could cut power consumption in half.?
NEC(跨國信息技術和電子公司)和NTT Communications(日本最大的電信公司)已開發出使用低壓制冷劑R1224yd的冷卻系統。
NEC, the multinational information technology and electronics company, and NTT Communications, Japan’s largest telecommunications company, have developed the cooling system using the low pressure refrigerant R1224yd.
據稱這是第一次將低壓制冷劑用于空氣冷卻。
This is claimed to be the first time that a low pressure refrigerant has been used for air cooling.
R1224yd實際上是一種HCFO,由日本制造商AGC旭硝子集團公司開發,是一種A1類不可燃制冷劑。它主要設計用于離心式制冷機,雙循環交換機和余熱回收熱泵。
Actually an HCFO, R1224yd was developed by Japanese manufacturer AGC Asahi Glass as an A1 non-flammable refrigerant. It was designed mainly for use in centrifugal chillers, binary cycle generators and waste heat recovery heat pumps.
NTT數據中心對該系統進行的聯合實驗表明,該制冷系統易于改裝,與傳統的水冷系統相比,制冷的能耗可降低一半。
Said to be easily retrofitted, joint experiments of the system at an NTT data centre are said to have demonstrated that the air conditioning power consumption can be reduced to half compared to conventional water-cooling systems.
There are also said to be plans to utilise the exhaust heat for secondary uses.

2017年,日本制冷劑制造商AGC旭硝子集團公司(AGC)宣布,其生產的新型低GWP值HCFO制冷劑R1224yd(Z)已經獲得了美國ASHRAE學會的認證。
新型R1224yd(Z)是一種A1類不可燃的制冷劑,主要用于離心式冷水機組、雙循環發電機和余熱回收熱泵。
AGC公司于2018年初以Amolea 1224yd作為產品名稱進行制冷劑的商業化生產。該公司表示,R1224yd(Z)的性能已經得到了日本和其他地區空調設備制造商的關注,并宣布日本荏源制冷公司已經決定在新一代離心機組中使用該制冷劑。

該制冷劑主要替代HFC-245f,其GWP值低于1,同時還顯示出與后者相當或更佳的制冷劑性能和穩定性。對于新設備,AGC公司保證新型制冷劑可以用于現有設備,無需進行大的改變。
