近日，兩家日本龍頭企業(yè)聲稱已開發(fā)出一種使用新的HFO制冷劑的數(shù)據(jù)中心冷卻系統(tǒng)，該系統(tǒng)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(guó)信息技術(shù)和電子公司）和NTT Communications（日本最大的電信公司）已開發(fā)出使用低壓制冷劑R1224yd的冷卻系統(tǒng)。

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(jù)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(shí)際上是一種HCFO，由日本制造商AGC旭硝子集團(tuán)公司開發(fā)，是一種A1類不可燃制冷劑。它主要設(shè)計(jì)用于離心式制冷機(jī)，雙循環(huán)交換機(jī)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(shù)據(jù)中心對(duì)該系統(tǒng)進(jìn)行的聯(lián)合實(shí)驗(yàn)表明，該制冷系統(tǒng)易于改裝，與傳統(tǒng)的水冷系統(tǒng)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(tuán)公司（AGC）宣布，其生產(chǎn)的新型低GWP值HCFO制冷劑R1224yd(Z)已經(jīng)獲得了美國(guó)ASHRAE學(xué)會(huì)的認(rèn)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(jī)組、雙循環(huán)發(fā)電機(jī)和余熱回收熱泵。

AGC公司于2018年初以Amolea 1224yd作為產(chǎn)品名稱進(jìn)行制冷劑的商業(yè)化生產(chǎn)。該公司表示，R1224yd(Z)的性能已經(jīng)得到了日本和其他地區(qū)空調(diào)設(shè)備制造商的關(guān)注，并宣布日本荏源制冷公司已經(jīng)決定在新一代離心機(jī)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(shí)還顯示出與后者相當(dāng)或更佳的制冷劑性能和穩(wěn)定性。對(duì)于新設(shè)備，AGC公司保證新型制冷劑可以用于現(xiàn)有設(shè)備，無需進(jìn)行大的改變。
