[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.

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。

[@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!

[@planeswalker00]

長智識了 ，原來係咁樣嘅，非常之有用😊

[@cheeheanleong2000]

多謝龍sir的解說，這一集學著很多。👏

[@TszhinChan-jt2tq]

有料到，冷氣佬都未必識

[@SiuManWong-bl7qe]

多謝龍Sir，知識的重要!

[@optimisticblackorange]

龍sir👍👍👍👍👍

[@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😂

[@Jharjit]

Lung Sir Bravo 👏🏾👏🏾👏🏾

[@TimothyYNWA]

龍sir始終都係咁可敬！真係得佢先講到衣d野我地聽

[@wongtszkit6274]

Wow….what a suprise info for me regarding EV !!!

多謝Lung sir🙏🙏🙏

[@lamlamlamleelee]

呢集真係好實用

[@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

[@ry6187]

Good job.

[@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！

[@newbro]

十分有用的資訊

[@takwong7016]

感謝龍Sir分享👍👍

[@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。

[@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

[@tsangpatrick923]

龍 sir 真有用 尤其贴隔熱纸 玻璃顶

[@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)
