Y’all bitches wanna hear some good news?

As of 2021, We actually reversed the progression of the hole in the ozone layer, and it is projected to be completely repaired by 2060. 🌍

Good job us!

…

For anyone born after Shrek 2 (2004) who might not know. HCFC and CFC emissions from, well, pretty much all aerosol sprays, globally, were damaging a portion of our atmosphere call the ozone layer around the poles. CFC were banned in Sweden in 1978 and many countries followed suit. They were internationally banned in 1987 and the ban took full effect in 1994.

Ozone, being a relatively weak bond of O3 in the upper atmosphere, prevented a lot of solar radiation from entering our atmosphere. It is essential to maintain homeostasis for our current biosphere ecosystems —It counteracts the primary source of global warming.

This was highly publicized in the 00s. Causing the same level of fear and anxiety as the oceanic acidity, marine pollution, and overfishing problems we currently face— but has kind of since fallen out of public consciousness like Y2K.

張敬軒Revisit演唱會之我見：令歌迷憤怒的劣作

在2022年12月20日，我和好友去觀賞了張敬軒宣傳多時的sidetracks大作: 張敬軒Revisit演唱會。(12月20日是頭場，同時是HCFC會員專場) 在購買門票時就已經是一波三折，因為雖然好友和我都是張敬軒歌迷會 (Hins Cheung Fans Club，又名HCFC) 的會員，但是這次歌迷會的安排十分不恰當，每位銀會員竟然只可以購買一張門票。只有在歌迷會網店消費滿$3000，升級做金會員才可以購買兩張門票 (即是俗稱「二連位」)，導致即使我和好友已經乖乖地課金去加入歌迷會，到最後都要淪落到我倆需要分開庭位去觀賞演唱會，這個「神級安排」實在令人啼笑皆非。據我所知在網上都有不少歌迷都對這個安排感到不滿，只是一眾網軍打手在網上帶風向，強行要求別人學習獨自去觀看演唱會，打壓反對的意見，去掩蓋歌迷會的安排不當。幸好當日去到現場，我的好友成功和一位女士交換了門票，令我們可以坐在一起欣賞這次的演唱會。在此要再多謝一次該名女士的慷概大方，願意臨時和我的朋友交換位置。

返回正題，這次的Revisit演唱會，張敬軒揚言會重遊過去20年的許多回憶，更會把許多的經典帶回舞台上。即是說這個演唱會是會以sidetracks為主，會為歌迷去獻唱一些非主打歌，但事實是否如此呢? 就是因為這次演唱會名不符實，才會令我感到如此憤怒! 在此我先定義一下我自己心中的sidetrack，第一個定義是比較客觀的，就是歌曲剛推出時沒有被歌唱公司用作專輯中的主打歌和沒有拿去派台的歌曲。而第二個定義則比較主觀，就是該歌曲當年是主打歌曲，但是其傳頌度不高，而且沒有或甚少在演唱會中獻唱。但問題是，這次Revisit演唱會的rundown當中，有許多歌曲是不符合這兩個定義的。所以與其說是sidetrack concert，倒不如說這次是「晒track」concert，把許多從前的滄海遺珠都浪費了。當然，即使是sidetracks，如果是平平無奇，根本沒有創意及衝擊力的作品，我都認為是不應該放上舞台的。

我順著這個演唱會的rundown由頭到尾去分析一次，看看這個演唱會的問題出在哪裡。開場的歌是《Deadline》、《Sweet Escape》、《Stop the time》所組成的快歌medley。這三首歌根本完全不屬於sidetracks的行列。《Deadline》是張敬軒在2011年的專輯《P.S. I love you》中的第一主打歌曲，而且在2014年中的《Hins Live in Passion》都以medley的方式出現過。《Sweet Escape》如果對於近幾年來開始關注張敬軒的人一定不會陌生，因為它正是最新專輯《The Brightest Darkness》中的主打歌! 而且在年初的《The Next 20》演唱會當中，它已經是主要rundown中的其中一首歌，所以都不是sidetrack。而《Stop the time》在過去的《張敬軒港樂演唱會》及《Hins Live in Passion》都是已經唱到耳熟能詳，再加上它本身都是一首派台歌曲。第一部份的這些快歌，就已經全部不是sidetracks。不過，張敬軒一直都是喜歡用快歌打開演唱會的節奏，而且這三首歌都是優秀的作品，自然是問題不大，而且都成功地把現場的氣氛炒熱。

然後就來到了《病況》及《攝氏零度》的部份，我要大讚的是《病況》的出現令人十分感動! 《病況》這一首sidetrack是源自《笑忘書》專輯的歌曲，繼上一次張敬軒在《The Next 20演唱會》中的encore以一個十分平平無奇的編曲 (其實我想說是比CD的編曲差許多) 去獻唱後，《病況》來到這一次演唱會，終於以一個比較成熟的方式去表演。作為張敬軒多年的歌迷，當然樂見張敬軒去唱出更多這些真正的滄海遺珠。但之後就還原基本步，他選擇了《攝氏零度》去緊接著上一首歌曲。《攝氏零度》不算是太差的歌曲，雖然它都有主打歌的普遍問題，就是旋律太flat、K歌味太重，但算是合格的作品。但是這首歌有另一個問題，就是它都不屬於sidetrack，因為它是《No. Eleven》專輯的主打曲及派台歌，同樣都有少少「唱到爛」的感覺，但暫時我認為還是可以接受的。

然後來到7首歌連唱的環節，順序是《風起了》、《夜宴》、《迷失表參道》、《狐》、《隱形人》、《傾慕》、《裝睡的情人》。首先第一首歌《風起了》，當我一聽到前奏，我就立即起身去廁所了。這首歌完完全全就是一個廁所位，因為張敬軒完全不適合唱這首歌，《風起了》的歌詞都完全不能引起我的共嗚，難聽點講，這首歌完全就是不好聽，不合格。由倪力原唱的《Marjoice》比起這個改到畸型的《風起了》是要好十倍以上。而且《風起了》都不是Sidetrack!當年英皇是有為這首歌製作MV的，誰膽敢說《風起了》是一首sidetrack? 這首歌既不好聽而且不是sidetrack，自然令我對這個show扣分不少。但之後《夜宴》出來，令我立即趕回去座位好好欣賞。要多謝吳林峰在上一次做張敬軒演唱會嘉賓時，把這一首佳作帶回上舞台，讓那位善忘的負心歌手終於想起自己曾經有這麼好的作品。《夜宴》的旋律雖然聽得出是以sidetrack的創作思路去寫出來的，但其詞曲的憂鬱感卻不輸他的主打歌，是屬於這次演唱會其中一個正確選擇。《迷失表參道》都是正常水準發揮，但這首歌都不屬於sidetrack，其實放它在中間，會不會反而浪費了一個位置呢? 張敬軒有這麼多sidetracks，是不是可以考慮轉唱其他歌曲呢?

來到《狐》及《隱形人》，這部份是我最喜歡的部分! 這兩首歌都是來自《urban emotions》專輯的sidetracks，兩首歌同樣都是屬於比較沉重的快歌，歌詞都帶有深度，旋律都是十分動聽，不是那種千遍一律的K歌。這兩首歌我沒有什麼可以批評的，這些選歌才是一個sidetrack concert應該有的選曲。只能講張敬軒環球年代的歌曲實在是十分動聽。緊接著的是來自專輯《Senses Inherited》的《傾慕》及《裝睡的情人》。《傾慕》的確都是一首比較冷門的sidetrack，但膽敢講一句，這首歌已經差不多是在《Senses Inherited》專輯中屬於最好的歌曲，輕浮再帶點迷幻的旋律，都是一個不錯的發展。但去到《裝睡的情人》，就突然來個大煞車了。《裝睡的情人》算是sidetrack嗎? 這首歌是有派台，英皇的網軍都曾經大力地推介這首歌給樂迷，而且在ViuTV的 Chillclub 都有唱過。um...... 但算吧，這可能算是給比較年資淺的樂迷的福利，加上這首歌的歌詞都帶有一個令人痛心的故事，我會給它合格吧。

然後休息一會後，來到自彈自唱《靈魂相認》的部份。這首歌是真的挺好聽的，是他過檔到英皇娛樂後為數不多的「軒式情歌」。好聽還好聽，但是這首都是屬於《Morph》專輯的主打歌。雖然他真的沒有在演唱會唱過，但他在剛剛的Music Panda都有和某大國文化歌手合唱過。算不算很短期內炒自己的冷飯呢? 哈哈。然後《遙吻》都算是以前的演唱會的常客，只是近年真的唱得比較少，要算作sidetrack嗎? 哈哈。一輪talk後，張敬軒就唱出《形影不離》，這首來自於《Sense Inherited》專輯，在民間支持度很高的sidetrack。我不反對他唱這一首歌，雖然它比較像是林家謙的歌曲，但畢竟都是沒有派台的sidetrack，都屬於是合格的選曲....吧?

然後來到第二個快歌環節，就是《懷舊情人》、《無城有愛》、《兩座位跑車》及《潛水》。前面兩首都是屬於韓風比較重的歌曲，但我個人就十分不受落了。新嘗試是好事，但如果你要Revisit的話，為何不先Revisit一下你2010年前的sidetrack呢? 順帶一提，《無城有愛》是最新專輯《The Brightest Darkness》的派台歌曲 (《懷舊情人》則是來自於同一專輯，HCFC的主題曲)。說好的sidetrack呢? 《兩座位跑車》就令我耳仔舒服不少，雖然都是萬年演唱會握手位歌曲，但相比之下格局比前面兩首歌要高，是屬於適合���敬軒的快歌。《潛水》就是另一個令人很R頭的選歌，其實如果力有不逮，就真的不要勉強。勉強是沒有幸福，要不然張敬軒你學林家謙一個很flat的tone 直接車過去吧。等等，《潛水》是有MV的，有MV的能算是sidetrack嗎? 哈哈。

然後來到了這個演唱會最令我憤怒的部份! 就是《過客別墅》、《叮噹可否不要老》及新編曲《雪花抄》的部份! 這部份完全就是一個disaster! 十分難聽! 先講《過客別墅》根本不是sidetrack，它是有MV的，請問邊到屬於sidetrack呢? 這首歌我曾經都在家中聽了幾次，然後果斷地把它從我的慣用playlist剷走。歌詞旋律平平無奇，沒有起伏，根本就是K歌一首。不是，是K歌都要比它好，K歌都要比它更有起伏。簡單講句，我根本不知道他在唱什麼。另外《叮噹可否不要老》都是同一個老毛病，都是平平無奇沒有起伏，而且最後還要消費一下以前��噹的配音員保全叔。我是來聽你唱歌，不是來看你賣慘的。你如果要賣慘，都麻煩你學上次《The Next 20》般賣你自己的慘，而不是為了滿足台下某種立場的歌迷的幻想而去消費逝者。最重要的問題就是這兩首歌就是垃圾! 說好的Revisit你的經典呢? 這兩首歌算是什麼經典? 用來賣錢的歌扮經典? 張生你有精神分裂嗎? 另外，新編曲《雪花抄》真的好難聽，真的好難聽。你以後的演唱會我建議你不要再唱《雪花抄》，真的好恐怖，我一年來聽到這首歌已經幾十次了，我不需要你在珍貴的演唱會時間再唱一次了。而且這些歌，邊撚到算係sidetrack呢? sidetrack呢? sidetrack呢? sidetrack呢? 你這麼多sidetrack去了哪裡? 掉進了咸水海嗎? 為什麼我真金白銀入場看你演唱會，你卻餵我吃屎?

到最後encore部份，張敬軒選擇表演了《悲劇人物》，這首的確是一首sidetrack，不過你在The Next 20演唱會已經唱過了，但這首歌總算令我的耳朵舒服一點。但是之後就真的是Disaster，而且是Civil disaster的級別! 為什麼要再唱一次《裝睡的情人》呢? 你說第一次唱得不好，但是第二次都不見得你有即時的大進步呢? 而且都係個句，台上時間有限。Don't fucking waste my time Mr. Cheung。你把一首歌唱兩次，很難不令我懷疑你根本在選歌方面準備不足吧? 然後真是 For the fuck sake，你為什麼要唱日文歌? 你為什麼要唱《First Love》呢? 你為什麼要懶好笑地準備一些音譯的歌詞在大銀幕上呢? 你這樣做是有什麼居心呢? 雖然不是十分難聽，但是我真係感到自己就黎爆血管啦張生......你有這麼多sidetrack不唱，唱了一大堆主打歌派台歌，encore環節卻俾這些貨我? 你沒有時間練歌就出聲，你就不要搞這個sidetrack show，本來這個show大部份的rundown已經離題，根本好多歌都不是經典的好歌，你最後還要唱首日文歌，是不是想我學國足球迷大叫「曰你媽退錢」你先開心? 你覺得你呢個rundown好好玩嗎? Fuck off, fuck off, fuck off。最後的encore 《老了十歲》，我已經沒好氣再聽及再思考。你喜歡這樣做音樂我都阻不了你。

總結而言，這個演唱會是正宗的「掛羊頭賣狗肉」，我不知道你Revisit了什麼才想得出這一個垃圾的rundown。Shit beginning, shit middle, and a shit end。如果你是一心想聽sidetrack而購買了門票的話，我建議你立即轉售手上所有的門票。張敬軒現在變得只會服務那些他轉會到英皇後才支持他的歌迷以及英皇娛樂公司。我想講你在環球時代的sidetracks呢? 為什麼不拿出來唱呢? 因為公司怕你以前的作品比現在更好聽更受歡迎嗎? come on! 你應該要用全sidetrack去排一個rundown出來! 不要輕易受旁人及利益左右。Show us your taste! 麻煩你真的用作品說話，不要得把口去做音樂，而係用你個heart去做音樂，好唔好? 即使比較近期的，例如《Morph》專輯中的《最卑微的願望》、《家園》及《一天》呢? 這個專輯是英皇時期的專輯，可以唱多點吧? 另外最後最後想講的是，如果你好想準時收工，少一點talk，取消植入式廣告的抽獎環節，這樣不就能解決encore太長的問題嗎? 歌手首先先要唱好歌，然後有空才搞其他事情吧，你連練歌的時間都沒有，我感覺昨日入場是被你欺騙了。希望你和你幕後團隊好好想想該如何進步。

Protecting the Ozone Layer - 35th Anniversary Edition.

The United Nations General Assembly established International Day for the Preservation of the Ozone Layer on September 16th, and commemorates the 1987 signing of the Montreal Protocol on Substances that Deplete the Ozone Layer that protects Earth against the harmful effects of ultraviolet radiation.

Marco Gonzalez, Stephen O. Andersen, and Sally Rand, with the United Nations Environment Programme’s Ozone Secretariat, will release a new book celebrating the 35th Anniversary of the Montreal Protocol. The book highlights successes and documents innovation during the first 35 years and inspires new ambition to strengthen protection of stratospheric ozone and climate before Earth passes tipping points.

The book tells the story of the Montreal Protocol, revealing a model of cooperation, collaboration, universal ratification, record of compliance with over 99 per cent of controlled ozone-depleting substances (ODSs) phased out, the ozone layer on the path to recovery, the 2007 Montreal Adjustment, and the 2016 Kigali Amendment moving the Montreal Protocol further into environmental protection.

Unfinished business includes: HCFC phase out, ODS bank management, HFC phase down, uncontrolled ozone-depleting greenhouse gas, nitrous oxide (N2O), feedstock exemptions for plastics production, and dumping of obsolete cooling appliances.

The book is anticipated to be released at 34th Meeting of the Parties to the Montreal Protocol on 31 October 2022

IL BUCO NELL’OZONO È DIMEZZATO: SI STA CHIUDENDO

Lo strato di ozono che protegge la terra dai raggi solari dannosi si sta ricomponendo ed ha raggiunto un calo record nella densità delle sostanze chimiche nocive che lo distruggono, ridotte del 50% rispetto ai livelli degli anni ’80.

Il dato è stato diffuso dall’ultima rilevazione della National Oceanic and Atmospheric Administration (NOAA), l’ente federale che si occupa di monitorare il buco nell’ozono, che 35 anni dopo il primo allarme lanciato dalla NASA ha definito questi valori una “pietra miliare significativa sulla via della guarigione”. Lo sforzo mondiale seguito alla firma del Protocollo di Montréal nel 1987 da parte di tutte le 197 Nazioni Unite, rappresenta la prima e unica volta nella storia in cui un trattato ha ricevuto una partecipazione unanime. Nel 2000 la produzione di CFC è scesa dal suo massimo di un milione di tonnellate (raggiunto nel 1988) a meno di 100.000 tonnellate per anno, grazie anche all’introduzione degli idroclorofluorocarburi (HCFC) che non contenendo atomi di bromo o di cloro dannosi per l’atmosfera. La progressiva riduzione della produzione di CFC in tutto il mondo ha permesso la drastica diminuzione del cosiddetto “buco nell’ozono” che secondo le proiezioni sarà completamente chiuso entro il 2070.

Il Protocollo di Montreal mostra come un’impegno preso da tutte le nazioni e rispettato con scrupolo può invertire un processo apparentemente irreversibile, diventando un modello e uno dei trattati più efficaci mai entrati in vigore.

Sometimes I think about how the hole in the ozone layer was such a huge deal when I was a kid. I remember hearing about it all the time in the 90s and early aughts, but today we don't hear much about it.

We don't hear less about it now because people don't care - we hear less about it because governments around the world stopped being cautious, decided to listen to scientists, and took collective action.

The action taken was staggering and eliminated production and consumption of the chemicals that were causing the hole. They just... eliminated them over the course of 20ish years.

It's possible to make that kind of impact, the governments of the world are just cowards and are in the pockets of big oil.

I was thinking about it today and reread a great BBC article by Kira Walker from 2022. I've linked it below and copied a part of it that ai find really interesting and important to understanding how change is possible, it just needs to be big changes without compromise.

In 1987, the Montreal Protocol was adopted to protect the ozone layer by phasing out the chemicals which deplete it. To support compliance, the treaty recognised "common but differentiated responsibilities", staggering phase-out schedules for developed and developing countries and establishing a multilateral fund to provide financial and technical assistance to help developing countries meet their obligations. During the 1990s and early-2000s, the production and consumption of CFCs was brought to a halt. By 2009, 98% of the chemicals agreed to in the treaty had been phased out. Six amendments — which the treaty allows when scientific evidence shows further action is needed — have led to ever-tightening restrictions on substances introduced to replace CFCs, such as hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs). While good for the ozone layer, these replacements turned out to be bad for the climate. The global warming potential of the most commonly used HCFC, for example, is almost 2,000 times stronger than carbon dioxide. The treaty's climate benefits have been a positive side effect. In 2010, emissions reductions due to the Montreal Protocol were between 9.7 to 12.5 gigatons of CO2 equivalent, approximately five to six times more than the target of the Kyoto Protocol, an international treaty adopted in 1997 that aimed to reduce greenhouse gas emissions. The 2016 adoption of the Kigali Amendment, which will limit the use of HFCs, will help avoid up to 0.5 C of global warming by 2100. '"You could argue [the Montreal Protocol] is a much more successful bit of climate protection legislation than any of the other [climate] agreements we've had to date," says Revell.' - What happened to the world's ozone hole? by Kira Walker

Brazilian Navy sinks the former aircraft carrier São Paulo, after several impasses

In a statement, naval force said that the procedure was done with safety and technical competence, in the late afternoon of Friday (3).

Fernando Valduga By Fernando Valduga 02/03/2023 - 21:58 in Brazilian Navy, Military

The Brazilian Navy sank in the late afternoon of Friday (3) the deactivated aircraft carrier São Paulo, which had been sailing for months in the sea after being banned from entering Brazil and abroad.

"The procedure was conducted with the necessary technical and safety competence by the Brazilian Navy, in order to avoid logistical, operational, environmental and economic losses to the Brazilian State," says the naval force, by means of a note (at the end of the news).

This Friday, the Federal Regional Court of the 5th Region (TRF-5) released the Navy to sink the aircraft carrier, rejecting a request from the Federal Public Prosecutor's Office (MPF), which saw serious environmental risk in the decision.

Three holes in the hull of the vessel caused the ship to fill with water, which made the sinking inevitable, according to an inspection carried out by the Brazilian Navy.

According to the document, if nothing was done, the aircraft carrier would sink uncontrollably until mid-February.

Risk of environmental damage

The Brazilian Institute of the Environment and Renewable Natural Resources (Ibama) evaluated that the sinking of the ship can cause the following environmental damage:

The release of polluting materials contained in the structure can cause disturbance in filtering capacity and difficulty of growth in aquatic organisms;

The physical impact on the ocean floor can cause the death of species and the deterioration of ecosystems;

Emission of gases (CFCs and HCFCs) used in the insulation of rooms contribute, from the corrosion of the walls, to the degradation of the ozone layer;

The carcass can attract invasive species harmful to native biodiversity;

Microplastics and heavy metals present in vessel paints can become protagonists of undesirable bioaccumulation in aquatic organisms.

Because of this, Ibama asked the Navy for information to study alternatives to reduce environmental damage. The environmental agency also wanted to map the bottom area of the ocean where the ship would be sunk.

According to the MPF, the scrap of the vessel has 9.6 tons of asbestos, a substance that has toxic and carcinogenic potential. The hull also has 644 tons of paint and other hazardous materials.

Aircraft carrier has three holes in the hull and should sink by the middle of this month, says Navy inspection

While wandering on the Brazilian coast, aircraft carriers forbidden to dock could have arrived in any port in the world, says former owner of the ship. According to Ibama, the ship did not carry toxic cargo, but hazardous materials are an "indissociable" part of its structure.

One of these materials is asbestos, a mineral fiber considered toxic. Currently banned in more than 60 countries, asbestos was used in several industrial segments.

Since 2017, a decision of the Federal Supreme Court (STF) has totally banned the use of asbestos in Brazil.

The Navy only took over the management of the aircraft carrier after MSK, the company that transported it between Brazil and Europe, threatened to abandon the hull in the middle of the ocean.

Toxic ship: understand why old Navy aircraft carrier is prohibited from doming

In the note released by the Brazilian Navy, there is confirmation that the old São Paulo aircraft carrier was shipwrecked in Águas Jurisdicionais Brasileiras (AJB), 350 kilometers from the Brazilian coast and with an approximate depth of 5,000 meters.

The document also says that the area “was selected based on studies conducted by the Navy Hydrography Center and the Almirante Paulo Moreira Sea Studies Institute”.

"The analyses considered aspects related to navigation safety and the environment, with special attention to the mitigation of impacts on public health, fishing activities and ecosystems," says the Navy's text.

According to the Navy, this place was chosen for five reasons:

Location within the area of the Exclusive Economic Zone of Brazil;

Location outside Environmental Protection Areas;

Interference-free area with documented submarine cables;

Area without interference from water works projects (e.g. wind farms);

Area with depths greater than 3,000 meters.

Experts said that the aircraft carrier could be sunk with the use of explosives. Wanted. The Navy did not detail the operation.

Here is the Official Note of the Brazilian Navy:

BRAZILIAN NAVY

NAVY SOCIAL COMMUNICATION CENTER

OFFICIAL NOTE

Brasília - DF. On February 3, 2023.

In relation to the hull of the former Aerodrome Ship "São Paulo", in view of the facts presented in the Joint Official Note of the Ministry of Defense, Attorney General of the Union and Navy of Brazil, it should be reported that the smoothing operation, through the planned and controlled sinking, occurred in the late afternoon of today (03), strictly as conceived.

The procedure was conducted with the necessary technical and safety competence by the Brazilian Navy, in order to avoid logistical, operational, environmental and economic damage to the Brazilian State.

The area for the final destination of the hull, located in Brazilian Jurisdictional Waters (AJB), 350 km from the coast and with an approximate depth of 5,000 meters, was selected based on studies conducted by the Navy Hydrography Center and Almirante Paulo Moreira Institute of Sea Studies.

The analyses considered aspects related to navigation safety and the environment, with special attention to the mitigation of impacts on public health, fishing activities and ecosystems.

Finally, the Brazilian Navy pays legitimate reverence to the former Ship Airfield "São Paulo". Boat that houses a belligerent soul perpetuated in the minds of men and women who garnished their conves, worthy servants of the French National Navy and the Brazilian Navy, under the aegis of naval traditions and high sailor spirit.

The R22 Revolution: Why This Type of Freon Must Be Banned?

The United States Environmental Protection Agency (EPA) has been phasing out the use of R22 refrigerant, or Freon, in an act that is phasing out products that are proven to deplete the ozone layer. By 2020, the production of R22 will be stopped in the US, which could cause problems for air conditioners made before 2010. Newer air conditioners use R410a refrigerant, an environmentally friendly option that might not be compatible for older air conditioners. With this change, the cost of adding Freon to older air conditioners will be expensive. Repairs and the new expense to Freon will build up quickly. In these cases, replacing your air conditioner to a newer model will be more cost efficient and lower your energy bills in the long run.

What is R22?

R22 is a refrigerant with the chemical formula CHClF2 or Chlorodifluoromethane. It is a hydrochlorofluorocarbon (HCFC).

How do I know if my system has R22 in it?

If it hasn’t already been brought to your attention by your service engineer, or you don’t have an asset list which will document the refrigerant in your systems, you can check for yourself by looking for an information plate on your system’s condensing unit. The condensing unit is the part of the system that is usually outside. And the data plate, usually located towards the bottom or side of the outdoor unit.

My system HAS got R22 in it — Is this illegal?

No. It’s not illegal to have a system with R22 in it, you can even use your system with R22 in it. You just can’t have it repaired. A service engineer can clean and maintain the unit, but he may not add any gas to it. This means that as soon as the system has a problem it becomes obselete and can not be repaired.

What are the benefits of replacing my R22 system now?

Air conditioning systems installed before 2004 are approaching the end of their usable lifetime, typically around 15 years with regular maintenance. Modern air conditioning systems come with huge advantages. They are smaller, quieter, more stylish and are 50% more efficient than those that operate using R22. Replacement solutions come with competitive payback periods, often just 2–3 years, and result in immediate improvements in performance. Replacement is also an opportunity to improve your organisation’s environmental credentials. Modern refrigerants, such as R32 and R410a, have a much lower impact on global warming than R22, while modern systems consume less energy and can considerably reduce your carbon footprint.These benefits and cost savings will continue throughout your new system’s lifetime, especially with regular maintenance, which will extend your systems parts & labour guarantee.

What Are The Advantages Of Using Freon Instead Of Ammonia In Cold Storages?

A refrigerant is a functioning liquid that is fundamental in the cooling pattern of climate control systems and intensity siphons. It is responsible for engrossing intensity from its environmental factors and delivering it somewhere else, permitting the framework to offer cooling or warming.

During the refrigeration cycle, refrigerants frequently go through stage changes, moving between the fluid and gas stages. This ability to switch states accommodates successful intensity move and permits the refrigerant to ship heat starting with one district then onto the next.

Nonetheless, due to the intrinsic dangers, the utilization of refrigerants is completely controlled. Assuming that unsafe refrigerants are spilled into the climate, they can imperil human wellbeing. They can likewise be truly combustible or unstable, expanding the gamble of mishaps or flames. What Are The Upsides Of Involving Freon Rather than Alkali In Chilly Stockpiles? We will examine these two gases in this article. Along these lines, continue to peruse to get familiar with it.

What Precisely Is Freon?

Freon alludes to a class of synthetic compounds known as hydrochlorofluorocarbons (HCFCs), chlorofluorocarbons (CFCs), and related substances. These substances are made out of hydrogen, chlorine, bromine, fluorine, and carbon. E.I. du Pont de Nemours and Company has reserved the expression "Freon" as a brand name.

One of the most widely recognized utilizes for Freon is as a refrigerant in different cooling frameworks. It helps with the support of low temperatures by flowing as a gas all through the framework. At the point when Freon gas retains heat from its environmental elements, it consolidates into a fluid and delivers the intensity outside. This method permits the cooling framework to keep the predefined low temperature.

What Precisely is Smelling salts?

In refrigeration frameworks, smelling salt gas is an ordinary refrigerant. Its significant job is to get and communicate heat energy away from the cooling system. Smelling salts is a normally unscented and vapid gas.

The solid thermodynamic properties of smelling salts as a refrigerant are one of its key benefits. It has a high inert intensity of vaporization, which suggests that as it vanishes, it can ingest a significant measure of intensity. Along these lines, it is very effective in eliminating heat from the refrigeration framework.

Smelling salts is likewise viewed as being earth useful. It has negligible ozone exhaustion potential (ODP) and minimal an Earth-wide temperature boost potential (GWP), going with it a well known decision in different businesses. It likewise has a low harmfulness level.

The Essential Qualification Among Freon and Smelling salts

What Are The Benefits Of Involving Freon Rather than Smelling salts In Cool Stockpiles? In chilly capacity frameworks, both freon and alkali are frequently utilized as refrigerants. While the two of them carry out the comparative role of cooling and saving transitory items, there are a few huge varieties between them. Here, we will take a gander at the advantages of utilizing freon as opposed to smelling salts in cool capacity. The upsides of cold stockpiling in farming require more exploration on this. In this way, we will make sense of it moreover.

The Advantages of Involving Freon As opposed to Smelling salts in Cool Capacity

What Are The Benefits Of Involving Freon Rather than Smelling salts In Cool Stockpiles? Coming up next are the principal advantages of picking Freon over Alkali:

Wellbeing: One of the essential advantages of utilizing freon in chilly capacity frameworks is its low harmfulness. In the event that there is a hole or openness, freon is non-poisonous and represents no significant mischief to human wellbeing. Alkali, then again, can be incredibly unsafe. Indeed, even minor amounts of openness can be destructive to human wellbeing.

Productive: Due to its outstanding warm properties, freon is a profoundly proficient refrigerant. It has a high intensity move coefficient, permitting it to quickly and really ingest heat from the capacity region. This proficiency supports the upkeep of the ideal temperature inside the cool stockpiling, bringing down energy use and working costs.

Flexibility: Freon has an extensive variety of refrigerant mix prospects, considering more prominent adaptability in chilly capacity applications. Different freon mixes can be picked in light of explicit cooling prerequisites, guaranteeing ideal execution across a wide temperature range.

Conversation on Utilizing Freon Over the Alkali

Each tough choice enjoys benefits and hindrances, and "Smelling salts versus Freon" is no exemption. Smelling salts, for instance, enjoys the critical benefit of making refrigerant releases "self-cautioning" because of its solid scent. The major and most serious disservice of smelling salts is that, in case of a coolant release, its "self-cautioning" nature makes it an objective for injury suit. Nonetheless, on the grounds that halocarbons are almost scentless, spillage frequently passes unseen by anyone other than the support work force. This diminished gamble of suit is a significant benefit.

The "Alkali versus Freon" banter isn't balanced; halocarbon refrigerants are feeling the squeeze to supplant smelling salts as a refrigerant. The mind-boggling smell of alkali noisily announces the dangers it brings, and it is all strong to the point that even in very low nonhazardous fixations, it gets individuals far from defiled areas. Albeit the gnawing is undeniably more serious than the woofing, the two principal inconveniences of using smelling salts as a refrigerant are the claim and guideline.

The greater part of huge scope refrigeration offices have customarily involved alkali as the refrigerant of decision. Throughout recent years, there has been a flood in the formation of new plants with under 2000 pull, as well as the change of smelling salts offices of this scale and more noteworthy to halocarbon. Actually plant supervisors and corporate board individuals are disregarding the utilization of smelling salts for halocarbon refrigerants to get away from disastrous legitimate and administrative repercussions following many years of powerful and deep rooted ammonium refrigerant use. Laborers at plants much of the time seek after private injury claims because of little, immaterial holes.

Primary concern

Smelling salts gas is utilized as a refrigerant in refrigeration frameworks to catch and communicate heat energy while keeping it separate from the chilling system. Refrigerant frameworks, for example, cooling frameworks, use freon gas to keep the temperature cool. How much refrigerant coursed by a smelling salts gas framework is 7 to multiple times not exactly that of a freon framework. Be that as it may, Freon outflanks Smelling salts.
