環(huán)境調(diào)查局（EIA）呼吁支持修訂后的安全標(biāo)準(zhǔn)，以允許在室內(nèi)空調(diào)中更多地使用易燃制冷劑。

The Environmental Investigation Agency (EIA) is calling for support for a revised safety standard to allow the greater use of flammablerefrigerants in room air conditioners.

環(huán)保組織認(rèn)為，國際電工委員會(huì)工作組提出新的IEC 60335-2-40安全標(biāo)準(zhǔn)是實(shí)現(xiàn)《基加利修正案》規(guī)定的最大限度減少HFC排放的關(guān)鍵。

The environmental group argues that the new IEC 60335-2-40 safety standard proposed by an International Electrotechnical Commission working group is vital to maximising HFC?emission reductions under the Kigali Amendment phase down.?

更改將增加標(biāo)準(zhǔn)的復(fù)雜性，但增加了安全措施以允許在房間空調(diào)系統(tǒng)中更多地使用A3和A2L制冷劑。

The changes would add greater complexity to the standard but with additional safety measures to allow greater use of A3 and A2L refrigerants in room air conditioning systems.

負(fù)載上限未更改。對于家用電器來說，每條線路的烴類化合物仍在1公斤左右，但該限定總是需要很大的空間。

The upper charge limits are not being changed. For hydrocarbons for indoor appliances it is still around 1kg per circuit, but this limit has always required a very large room.

所更改的是標(biāo)準(zhǔn)大小房間中可以使用的量。在20平方米，天花板高度為2.2m的房間中，對于標(biāo)準(zhǔn)分體式系統(tǒng)，如R290之類的A3可燃制冷劑的當(dāng)前負(fù)載仍為334g。

What is being changed is the amount that can be used in a standard size room. The current charge for an A3 flammable refrigerant like R290 for a standard split system in a 20m2?room with 2.2m ceiling height remains at 334g.

在一個(gè)類似大小的房間中，新提議將允許多達(dá)988g的R290，并具有更堅(jiān)固的系統(tǒng)設(shè)計(jì)，增加的氣流，檢漏儀和安全截止閥。

In a similar sized room, the new proposals would allow as much as 988g of R290 with a more robust design of system, increased airflow, leak detectors and safety shut-off valves.

對于具有A2L制冷劑和多個(gè)室內(nèi)機(jī)的系統(tǒng)，當(dāng)前的充量限制已經(jīng)很復(fù)雜，需要考慮其他安全措施?？傮w結(jié)構(gòu)沒有改變，但是允許的A2L填充量增加了。例如，對于具有堅(jiān)固設(shè)計(jì)的R32系統(tǒng)，該系統(tǒng)可為三個(gè)帶有吊頂單元的房間提供服務(wù)，每個(gè)房間的面積為15平方米，天花板高度為2.2m，如果不采用其他安全措施，當(dāng)前標(biāo)準(zhǔn)允許使用2.5kg的R32。在新提案中，此限制為7.5kg。

For systems with A2L refrigerants and several indoor units, the current charge limits are already complex to take additional safety measures into account.?The overall structure is not changed, but the allowed amount of A2L charge is increased. For instance, for an R32 system with a robust design serving three rooms with ceiling-mounted units, each room being 15m2?with a ceiling height of 2.2m, the current standard allows 2.5 kg of R32 if no additional safety measures are applied. With the new proposal this limit will be 7.5kg.

EIA英國氣候運(yùn)動(dòng)負(fù)責(zé)人克萊爾·佩里（Clare Perry）表示：“采用修訂后的安全標(biāo)準(zhǔn)以允許室內(nèi)空調(diào)中使用易燃制冷劑，對于實(shí)現(xiàn)氣候目標(biāo)和執(zhí)行逐步淘汰 HFCs的協(xié)議至關(guān)重要，例如《蒙特利爾議定書》下的《基加利修正案》。

“The adoption of a revised safety standard to allow flammable refrigerants in room air-conditioning is vital for meeting climate targets and implementing agreements to phase down HFCs, such as the Kigali Amendment under the Montreal Protocol,” said EIA UK climate campaign leader Clare Perry.

EIA高級氣候政策分析師、UL 60335-2-40美國標(biāo)準(zhǔn)技術(shù)小組成員克里斯蒂娜·斯塔爾(Christina Starr)補(bǔ)充說，各國支持這項(xiàng)提案，以充分發(fā)揮減少HFCs和提高制冷能源效率在氣候方面的全部好處，這是極其重要的。

It is incredibly important for countries to support this proposal to unlock the full climate benefits of reducing HFCs and increasing energy efficiency in cooling,” added Christina Starr, senior climate policy analyst with EIA, and a member of the US standards technical panel for UL 60335-2-40.
