[Lung Sir Academy Ep19] Electric Vehicles Lesson 4: The air-conditioning system

Since the government launched the One-for-One Electric Vehicle Replacement Plan, Hong Kong electric vehicles have mushroomed and dominated the Hong Kong new car sales market in a short period of time. Whether they are European electric vehicles, Japanese electric vehicles, or even new Chinese electric vehicle brands, they have also On sale in Hong Kong. Electric vehicles, a new type of vehicle, have many advantages. However, because the innate design of electric vehicles is very different from gasoline vehicles, electric vehicles require drivers to learn or adapt in many aspects. After Long Sir Academy explained the characteristics of different motors, the control characteristics of electric vehicles, and the brake design of electric vehicles in the "Understanding Electric Vehicles" series, this time we came to the place where Lung Sir thinks electric vehicles are most different from gasoline vehicles - Air conditioning system. You may be using an electric car, or have ridden in an electric car. Why is the air conditioning control in the car always weird? It is either too cold or too hot, and it is not as stable as the air conditioning of traditional gasoline cars. Lung Sir will explain to you this time. This is also the Achilles heel of electric vehicles. So far, it has not been able to completely achieve the air conditioning as good as that of gasoline vehicles. He also recommends that electric vehicle users should pay attention to this when purchasing glass insulation stickers. thing.

幾時都話香港咁多個講車channel，得龍Sir係學到嘢返屋企

[@4MK_4MK]

解釋咗好多好多疑惑

[@周镇峰]

高見，老蝦搞是有料到

[@chiellinilee5152]

真真係

[@Hi-vr4mv]

👏學到野，多謝龍sir👍

[@1218keith]

龍 sir, 每次都深入淺出，解釋清楚易明 👏 #電動車 #冷氣 #發霉

[@htwong31]

龍Sir真係真正汽車專家👍🏻

[@tylerng688]

香港人有rev真係好幸福🎉

[@carjaswong]

絕對是全港最有質素的車評網.

[@kuang01]

我反對。你講得唔岩。其實係全球最有質素。 因為全世界都無人講呢d實際野。一係吹捧，一係全踩。

[@eddycheung7784]

龍sir，聽完您講解👍，Hybrid應該可以平衡到油價和舒適的需求。🙏

[@Ben-uw3vv]

龍sir, 一語道破！
可能係RUclips 界第一個人講呢個死穴嘅Channel 添！

[@雲在天-q7v]

多謝龍Sir的分享🙏👍

[@manchan2016]

龍sir真係香港咁多汽車頻道最有知識嘅一個，每次講解嘅複雜教學都將佢簡單地表達👍🏼👍🏼👍🏼

[@GRT1]

正，到無話可說，龍大師一語道破，問世間，車為何物😂

[@louispoon4495]

比龍sir罰留堂真係甘心情原，真係學到好多野，勁
記得舊BMW比較特別，要手動係兩個冷氣出風口中間有個制去調較熱水哇佬既流量先有暖氣出，如果吾係個温度制SET到33度都吾會有暖氣

[@Li-ms9pw]

有質素的頻道！👍👍

[@alexalex-bk5ls]

清晰、精要、有益消費者👍

[@richardwu1952]

You resolved my long standing question on sun-roof and humidity management in EV. Fabulous and simple explanations. Lung Sir.👍

[@sir167]

謝謝！😊

[@netmatrix75]

Its amazing that after so long in EV existence, there is almost no one that elaborated how the AC system works and why the glass roof is needed. I think Elon did mention a little bit about it. But there was never a mention that it was related to the AC system. Seems like this video is the pioneer to elaborate about this! Great content!

[@devilking55699]

多謝龍sir指點,講解得非常清楚,連我呢啲中佬都一聽就明,支持你

[@edwardcty6808]

龍sir有信譽！之前應承出片講解電車和油車冷氣分別！現在出了❤

[@kaicheongchang4367]

佢唔明白油車冷氣怎样功作😅

[@PaulKeeWong]

係呀，我在加拿大冬天揸車，日間有太陽，但出面係負10幾度，坐係車入面開咗一陣暖氣或暖櫈就要調返低，因為太陽晒入來，你會Feel到係辣手，好熱，但你一出車門一陣，凍到變雪條....

[@sir167]

在北美這個太陽頂非常重要，千萬不要貼阻隔infrared的太陽紙，否則電池好快冇電😂

[@shgme7105]

正 多謝分享

[@NotTophatC0rksw3lla]

龍sir講車真心正

[@AlexLiuHK412]

日頭曬到正，真係好攞命。👍押韻

[@L_K_K]

又長知識了，龍Sir勁呀👍🏻多謝龍Sir🙏🏻
可以大膽講句：無睇呢集，真係走寶！❤

[@sanjitsha6639]

多谢龙 sir 与 RevChannel 。龙sir 对电动车的空调系统的讲解非常好。对于电动车的空调系统使用方法也非常适用。太好了。

[@cheeheanleong2000]

多謝龍sir的解說，這一集學著很多。👏

[@planeswalker00]

長智識了 ，原來係咁樣嘅，非常之有用😊

[@菇菇菇-o5c]

其實玻璃頂好大程度係釋放車廂空間，因為動力電池占用左車廂空間，傳統天窗厚、安裝成本高過玻璃頂。動力電池加高左車身，玻璃頂一舉多得。

[@mlau9991]

制热能力，电车不如油车，因为油车引擎本身就不停发热，可以将这些热量加以利用，所以油车”制热“不成问题，效率很高，相比之下，电车制热效率就不高了；但说到制冷，电车油车两者差别不大。

[@张颖-j4w]

制冷能力，电车比油车功率大很多，因为不单单车厢需要制冷，还有快速充电时候电池都需要恒温

[@dontbotherme-v4c]

龍Sir 講中晒。電車冷氣真係有啲麻煩，但係記緊用吸濕象，再加上吸味炭，有好大幫助。

[@hong191084]

龍Sir真材實料！！！！

[@nakamuragames]

龍sir唔講我覺得我呢世都唔會知
請繼續出呢個系列🙏

[@keithwong2638]

龍Sir 係汽车博士，當之無愧👍🏼

[@ninjatvhk]

聽龍Sir講車真係學到野👍👍👍怪唔得有時我想較凍D，佢出一陣暖氣先識凍😅😅😅

[@及企一任強不月此]

龍sir對車與物理知識博大精深。

[@marcomak8061]

龍sir好嘢👍，令大家又學多樣知識👏👏👏

[@cheungwanfung3008]

多謝龍Sir老師❤

[@TimothyYNWA]

龍sir始終都係咁可敬！真係得佢先講到衣d野我地聽

[@prosushicfu9198]

勁，學到啲冷門得實用嘅知識！多謝龍Sir！

[@joerover]

最煩冬天、落雨天一定要開冷氣先可以除走大銀幕D霧氣！反而電車可以考慮加附"熱石式"抽濕！我衣櫃長期都係用佢！以車箱用電量算低啦！又靜！

[@pingo049]

電車個冷氣真係好唔舒服，如果你凍少少開暖氣更加辛苦，唔係自己揸車既時候坐隔離真係頂唔順，還有就係如果落雨開雨刮，個雨刮檔位大少少，你會發現部車個電力續航去得好快。

[@kevinbig9164]

請教下點解雨刮影響咁大嘅

[@laijacky4840]

早排先喺度關心緊點解電動車啲冷氣咁差但係搵唔到答案
估唔到隔左一排龍sir就出左條片講呢樣野🙈🙈
多謝龍sir

[@mannice9495]

學到野 🎉立即like❤

[@axemanwong1]

Thank you 龍sir. You are the best. You are really a walking encyclopedia.

[@SunLau]

龍Sir d片真係好高汁!
學到野

[@tomwong606]

日產 Serena E power，車廂中排腳位，左右各有一個氣孔，說明書話係散熱用勿遮閉。我一直都唔明，個車廂（夏天）梗係想涼啲點會散熱喺個車廂內。睇黎龍 sir 解釋咗個原因。又似乎日產既工程師真係諗得好仔細，要俾佢地一個👍

[@torque-converter-w2y]

果兩個唔係驅動電池散熱排風口嚟？
呢啲七八人車 車頭暖氣口向前排錶版台底
車尾暖氣口就向輪拱殼度(睇車尾套冷氣風機擺向左邊定右邊)

[@snowman1221]

上完堂，又長知識，多謝龍Sir 🙏

[@soundbarguy]

長知識🙏🏻 原來電車和油車有這個分別👍🏻多謝分享

Good Evening Sir~~

高温易燃，低温亏电甚至充不了电😊

[@wongtszkit6274]

龍Sir 勁

[@kingwing83611]

學到嘢，多謝龍sit🫡

[@ac-stingz]

Tesla 除咗heatpump都仲有compressor同埋octovalve可以解決到大部份問題之外，佢其實仲有抽濕劑幫忙抽走空氣水份。covid期間我試過負10幾度要喺呢邊嘅急症室外面等家人5個鐘（家人唔比逗留），如果唔係電車可以唔使着engine就開暖氣，果次都會幾麻煩（至少唔驚中毒）。

[@sir167]

Octovalve的功能就是改變系統的冷熱水流向以適應不同的情景的熱管理需求，電動車以停車開空調，的確是個大優點。

[@cancherie38]

出面負10幾度唔比係醫院等？一個家屬都唔比？

[@ac-stingz]

@@cancherie38 covid期間只可以喺waiting area等到醫護接走病人入診療區，之後家人一個都唔準逗留，病人唔識中文佢有華裔護士幫手。

[@pkny9394]

Really like the way you explain things, very easy to understand. Hope you can talk more about the thermo system in the future

[@peteryau80]

聽龍SIR講完,明白有時係要俾D熱入車籠令冷氣泵工作,又學到野.😀

[@MrMessy1986]

其實講到尾係energy efficiency嘅問題，燃油車唔係比較好，而係佢將無可避免要浪費嘅能源（廢熱）搵到利用嘅方法（抽濕）。電車做唔到傳統上嘅額外好處係因為佢浪費嘅能源唔夠多，變咗要抽濕就要用其他方法；要解決呢個問題，喺新型電池大幅提升energy density同續航力，大到可以額外同時運轉抽濕系統又不降低cruising experience之前，車主就需要外置一個車內抽濕裝置。

[@khkckhkc]

Informative and insightful, I often wonder why most EVs come with such a large sunroof.

[@sir167]

是的，個中原因秘而不宣😅

[@matthewlee3206]

支持龍sir出書🎉🎉

[@mrho8654]

真正認識汽車的學者

[@beanywang9859]

家里纯电动车, 因为没有引擎不发热, 经常导致车里发霉发臭, 后来软件更新了好几次, 把软件策略优化到极致才解决问题.

[@beanywang9859]

结合我个人多年体验, 这个确实是一种少人聊的秘笈

[@TCTheGreat]

冷天落雨，唔開得窗，玻璃積曬霧水，夜晚外邊黑嘛嘛，咁就一定要開冷氣抽濕，如果真係凍得濟，可以考慮燒下炭

[@georgewong2272]

Thanks Lung Sir 👍

[@newbro]

十分有用的資訊

[@SiuManWong-bl7qe]

多謝龍Sir，知識的重要!

[@Stepheny15]

我只知道如果唔好好保養架車，不論電動車或汽油車，所有野都係死穴。😂最好就係去原廠定期保養，不過價錢一定貴。都要睇荷包做人。😢！唔好樣様到dead line 先維修，到時候一炮去維修🧰，又係自己搵自己笨。仲貴。

[@tsangpatrick923]

龍 sir 真有用 尤其贴隔熱纸 玻璃顶

[@truckM16]
