You have done so much research, using exhaust fan and the temperature module, just to practically show us the difference and help us benefit from such method. Your hardwork is commendable
Thank you very much for your appreciation and support 😊🙏
It's not as powerful as I thought it would be, but it works very well. ruclips.net/user/postUgkxGjG43--gYqIoT4Xkur2PqCrtbKwTv2h6 There are three options to circulate air, and best of all a remote control for us lazy people. Installation was a breeze (no pun intended). It actually took longer to open the box then it did putting the side extenders on and sitting it in the window opening. It's a perfect alternative when you want airflow, but not the AC. Just might order another one for a different room. UPDATE: Bought another one like I said. They work great. Why not have two...
I am happy that you liked the idea 😊💡
Ram Ram sir 🙏 Appreciate ur efforts for elaborating everything practically with zero confusion.... U r great 🙏
Thank you so much for your appreciation 🙂 do subscribe if you like my content. Warm regards from Pune, Maharashtra, Bharat
Do saal se yah kar raha sir, bahut fark padta hai, very scientific, thanks so much. 🙏
You are most welcome 😊🙏 you are helping nature as well as our nation to save valuable energy 🇮🇳👍
One of the finest video. To the point and practical. I really appreciate the temperature gauge you developed and the graphs. Also appreciate the lady whos helping you in creating this video
Thank you so much for your appreciation 😊🙏 I am happy that you liked the content 👍
Thanks for sharing your results. This kind of content from well planned experiments is what will make a big difference. I hope someone picks up this idea and and advances into a product so that this can benefit everyone. Imagine this becoming part of the A/C which already has most the needed elements.
Yes..
And for me it has saved electricity bills this summer 😊👍
This is best idea though. For evening & night actually as temperature outside is cooler than room so it will drag cool air in the room.
Completely agree ..
God bless you 🙏
For ur hard work to making this experiment
Thank you very much for your appreciation and support 😊🙏
Great sir, long time searching for this kind of experimental video. Thank you 🤝
You are most welcome 😊🙏
Believe me your idea changed my room temperature. I am delighted. Last night it was around 30 degree census temperature outside but for me It's cool inside my room. I used two fan in two different room but the fan which i used to bring cool air inside my room worked best. I used 12 inch fan which is enough to cool my room. I use another table fan to spread my cool air around my bed which worked as air curtain. Thanks for your innovative experiment.
I am really happy that this idea worked for you saving valuable energy sources using an AC
😊💡👍
Bahut achchha aor labhkari video!
mai bhi esi trah ghar ko naturally cool rakhne ki kosis me rehta hu
aapke en efforts & video ko hindi me bnane ke liye dhanyewaad!
You are most welcome 😊🙏
Very Detailed and Methodical experiment. Loved it!
Thank you very much for your appreciation 😊🙏
Tried this and it really works like a charm. Only thing to add is a mosquito/insects net on the outer side is needed if you are living on ground floor. Thanks Mahesh. 👍👍👍
You are most welcome 😊🙏 I am happy that you used the idea and saved some energy for our country 🇮🇳🙏
My dude, you are goals! I too was thinking of doing this and came across your video.
I have a major concern for the mosquitoes entering, though.
You may like to use mosquito net at suction area plz 🙋
Awesome experiment and great explanation! This is what I was looking for and trying to implement!
I am happy that you liked the experiment... Hope it will save energy and money for you 😊🙏
This seems so cool. Thanks so much for sharing. It's a good setup for times when your running a cooler at home at night.
You are most welcome 😊🙏
I really appreciated you have done a quality research regarding the Exhaust fan ❤
Thank you very much for your appreciation 😊🙏
We appreciate your effort sir, it was really helpful, Thankyou!
You are most welcome 😊🙏
And thank you so much for your appreciation 😊
Appreciating you for the concerns towards environment. Thanks keep doing more practicals.

Exhaust fan usually draws out hot air from the room to outside. What is needed is a ventilation fan, which will pull or draw the cool air from outside and an exhaust fan on the opposite end which will drive away the hot air outside. Or the fan which u have installed on your window must have a duel mode...... And another valid point hot air normally rises up, so to drive it out the exhaust fan should be fixed at a higher level. Just a suggestion from my end....
Initially, I purchased a dual-mode fan for this experiment. However, I encountered two issues: inadequate airflow and excessive noise. After multiple trials, I opted for this fan and installed it in reverse, addressing the issues you mentioned. Therefore, the factors you mentioned were indeed experimented with, and the final solution is presented in this video.
Please do subscriber my channel 🙂
How does a fan knows if the air is hot or cold?.
@@sdhineshkumar1984 fan indeed does not know if the air is hot or cold, to check you can use simple and cheap digital temp gauge (~150 Rs) - see use of it in video
Superb sir, you have done very useful experiment that practically working very well. Big thumbs up for your dedication and hard work to conduct this experiment. I would love to try this
I am happy that you liked the experiment, thank you so much for your appreciation 😊🙏
thank you sir for your informative video- i believe you are an engineer, because one can understand from the commitment & detailing you have put into the project.
You are most welcome 😊🙏
And thank you for the appreciation
Very detailed n helpful. I would be very happy if one more video is created covering day time cooling of room without airconditioner.
Actually as you can see in temperature graph, during daytime, outside temperature is more than inside just using ceiling fan helps. During daytime exhaust fan is not useful both inward or outward direction.
For daytime cooling I recommend using heat reflective paint which will drastically help reducing daytime heat coming from roof

Thank sir for information and your hard work ❤❤❤❤
You are most welcome 😊🙏
Thank you sir for the research and results shared … Very nicely explained!!!
You are most welcome 😊🙏
I got this idea in my mind and searching that there is any one who used like that and then i got this video. .. thanx for suggestion
You are most welcome 😊👍
I am using it till today... It has saved a lot for me each summer
Being an engineer , i have successfully droppod 7 - 8 degree temperature.
Certain recommendations.
Use a cooler and exhaust fan combo.
Use dimmer in both
Adjust height of both as per warm and cool air separation.
Observe temperature, pressure zone and natural wind circulation pattern for easy exit of hot. Air and recirculation of cold air.
If you need i can send u pics of my successful project.
That's really good sir.... Kindly send pictures of the setup on mahesh@trekbook.in
Warm regards, Mahesh 😊🙏
can i contact you?
@@memic3511 yes please. send your phone number to mahesh@trekbook.in and I will call you
Fantastic video. great efforts. keep it up, this nation needs you---.
Thank you so much for your appreciation 😊🙏
Thank you for such kind of video.. 🙏🙏🙏🙏🙏
You are most welcome 😊🙏 I am really happy that you liked the video
Interesting, liked how detailed the video was.
Thank you very much for your appreciation 😊🙏
If you have a bathroom attached to the bedroom and has an exhaust fan, keep the door open and run it , to send out the hot air. In addition, you can attach an exhaust fan to the window opening to bring in fresh, cool air thro' bedroom windows - it will immediately start chilling the room. Spraying water in the room with an empty Colin Spray bottle will further bring down the temperature
👍 Only issue you might have to face is smell...
I was planning to do this for long time but was sceptical about the results. But your video gives the confidence.now i am going to try it. Thanks 🙂
You are most welcome 😊🙏
Is there any exhaust fan available which is bidirectional 2way switch ? Or revering the current would make it run anti-clockwise?
@@eurolife1117 yes, it is available. amzn.to/3pOdPEa
Very well made. Kudos.
Thank you very much for your appreciation 😊🙏
Very helpful, thanks 🙏🙏🙏
You are most welcome 😊🙏
Having ceiling exhaust rather than on the window will improve the cooling effectiveness and if you pair it with a pedestal fan blowing air from outside to the middle of the room in the evening makes the room very cool for good nights sleep 🙂
Yes, perfect 👍
Appreciate your efforts in giving insights of using exhaust fans. I was looking forward for such experimental videos for long time. Although it was not very effective in your case I think use of both exhaust and intake fan together would make it even more better.
Yes, using 2 fans surely helps.
In my case right now while writing you reply my exhaust fan is running giving me a cold breeze ❄️👍
Amazing work Sir.
Thank you very much for your appreciation 😊🙏
Very nice video sir .
Well explained,
Thank you very much 😊🙏
I tried it very excellent 👌 working i love u sir
You are most welcome 😊🙏

Thank you very much for your appreciation and support 😊🙏
@@TrekBookIndia its my pleasure sir 🙏
Very nice video, great work
Thank you very much ☺️🙏
Excellent sir, U r genius sir
Thank you very much, 😊🙏
Fantastic effort sir.
Thank you very much for your appreciation 😊🙏
Your experiment is helpful.
I am happy that it helped you 😊🙏
Great video. I am doing a similar experiment with my room and washroom. I started testing with washroom and it worked very well. Just one suggestion : you should also mention which city you are living and how is its weather. I think the humilidity level and the month of the year also matter alot.
Agree .. I missed to include the city which is Pune having dry weather compared to coastal areas // month of the year is May .. and this year also I used this a lot avoiding use of AC at home
Awesome work
Thank you 😊🙏
Very good experiment, thanks for the great work. This experiment will be really helpful for those who can't afford AC and it will help mother nature too. As Celling fans using the same air in the room it increases room temperature and CO2 level also get increased over the night. So here the important thing is we need to expel the air inside the room.
I am proposing like we can make two exhaust holes on top both corners of the room the hole size as like in kitchen. We can use two exhaust fans one for fresh air inlet and another for outlet, so that we can ensure the same exhaust air not circulated back through inlet fan, here the distance between the two fans are important. So, the main advantage of using the exhaust fan we will get fresh air all the time. We can cover the holes outside with mosquito net to avoid mosquito and insects and we can use steel grills for safety purpose.
Sometimes the inlet air drawn by 9 inch exhaust fan many not be sufficient. In that case, we can use only one exhaust fan to expel the air outside and we can keep another hole open, so that as usual by using our regular celling fan we will get fresh forced air inside through the inlet hole. As per law of equilibrium once we expel the air from room automatically the fresh air will get inside the room to fill the vaccum created by the exhaust fan.
If you think this idea has some sense, I Kindly request you to carry out experiment on this and post the results. Thank you.
Thank you very much for sharing your ideas in great details...
Surely I will try it next summer ... 😊🙋
Nice initiative, towards environment
Thank you very much for your appreciation 😊🙏
Great Effort 👍👍
Thank you very much 😊🙏
i thought i was the only one obsessed with ventilation
good to see it
Thank you so much ... we think alike 🙂
If you have thought of more such ideas please let me know . and I will try them as the time permits ..
I used inside outside thermometer, its a single device that shows both the temperatures on the same screen. For bringing outside air we just kept the doors and windows open through out the night, allowing to exchange automatically. I fixed mosquito nets at all places which were kept open. It really helped to reduce use of airconditioner.
Perfect 👌👌
Energy saving by any means is help to our nation 🇮🇳 🙏everyone should try such small things
Nice i will definitely try
😊 It's working fantastic at my home and this summer till now I have not used my AC
Great Sir.
Thank you 😊🙏
Perfect case study 🎉
Thank you very much for your appreciation and support 😊🙏

Good Video sir
Thank you 😊🙏
The exhaust fan experiment was efficient during the day but I will say it was quite inefficient during the night.
I will say a more efficient setup during the night would have been to keep all the windows open and putting another exhaust fan on the opposite end of the room to trigger airflow this way cooling at night would be much more efficient and the room would cool to the outside temperature by the next morning.
This I have tried... Believe me it won't work...
Finally I am able to live without AC this summer with thus setup... Only thing is I live in pune where temperature outside drops surely at midnight... 🙋
Being worked in R&D over 30 years I have learned that many things ghat we assume based on theory do not work out practically... Similarly here practically what works that I have shown 🙏
@@TrekBookIndia Ok then
very good
😊🙏
Good work 👍🇵🇰
Thanks for sharing the suggestion to slide the windows down for few minutes before turning on A/C. I wish an cars have mechanism to turn on automatic exhaust when temperature inside shoots up. We can be sure that it is sunny when this happens, so coupling it with a solar powered system should work. Perhaps this could be an ADD-ON by vendors before it becomes accepted by car manufacturers
Very good suggestion of automatic exhaust 👍
Available in tata cars
As express cooling in which all windows of car goes down for some time
This is so cool
Thank you very much 😊🙏
i think you should try this..
1. check for thermal leakage points in ur room. outisde heat should not enter the room via windows,the window channels and grills. they r the first points of convection
2. once room is thermally insulated, place 2 exhaust fans one in the direction of natural outside airflow(south direction) and another in north direction. pull the air inside from south direction and let another exhaust pull the stale air from inside and throw it out from north direction. this creates natural flow of air in the room.
3. choose an exhaust fan which has higher airflow lower power consumption like the atomberg bldc fans. if there is problem pulling air from south direction then connect a high speed inline duct extractor. that way u can also eliminate fan noise.
4. u can actually use a power efficient bldc motor in an air cooler and let it generate its own cool air, while one of the exhaust fans can replace the stale humid air thereby efficiently reducing temp
Thank you very much for your detailed suggestions ☺️🙋
As on now I am getting satisfactory results with the makeshift arrangements done for the video... So just continued to use it... Let's see as the summer intensifies if I need to put one more exhaust fan or not 😎🌞
Definitely I will use this trick and thank you so much for making this video.
You are most welcome 🙏
Just for info that I am still using this even in month of May
I think this year in total I have used my AC only 3-4 times when it was extremely hot, rest time I used exhaust fan 💪😊
@@TrekBookIndia that's great. But I don't think we can use it in the month of May and June in Odisha.
@@TrekBookIndia I like your experiment it's just awesome.
@@ShiningStarOfficialChannel thank you... Actually this experiment was in my mind since years, but due to the job I couldn't do it. As soon as signed off from my job I got time to do such things 😊💫
@@ShiningStarOfficialChannel Agree,,,, since I stay in Pune .. even in summer the temperatures are not that high .. so here its quite possible ..
Excellent guide
Should I use two fans one for out & one for in as suggested by you or can I use one bidirectional fan with changing it every hour by timer .
Which unidirectional fans are are godd for in & out.
Also which bidirectional fan is good
I suggest to use unidirectional fans,
Fit one at lower level from ground (max possible) driving air inside and second driving Air out of the room at highest level from floor (ground)
As of now I am using only one fan, but thinking of adding one more to drive the air out (faster results)
@@TrekBookIndia Thanks,.
Any recommendation for fans for incoming & outgoing.
Also one time I woul like to say that , very good scientific videos.
Great
Thank you 😊🙏
Great news
😊
You are very intelligent
Thank you very much for your appreciation 😊🙏
Good
Thank you 😀
Mid day the temp difference with the exhaust fan on sometimes gets to 7-8c depending on how high the temp is. 2-3 weeks ago we were getting 41-46c in my city.
As per my experiment, it's effective only during night time
which would be the best 2 way low noise fan ?
and to make it 2 way do we need to have separate switch set up or just turn the plug and put and it works other way around ?
Two way fans are made by local companies and metal blades, they are noisy. If you see my video, the experiment began with the 2 way fan, but later I returned it due to high noise and low air throw and went with खेतान branded plastic one way fan which has good air throw and low noise
For 2 way local made fans, they give reverse switch to change the direction
Just an example of duel direction fan where you can see the direction reverse switch amzn.to/3wnF6jr
The exhaust fan creates negative pressure inside and it is sufficient to pull the cool air from outside from the windows. So another inlet fan to let the air inside is required?
The factors influencing the choice include room size, window size, window placement, and the number of windows.
This can be assessed through either expensive CFD analysis or practical experimentation with single or multiple fans.
If you like the content of my channel please do subscribe since I get only 100 subscribers per month 😅
No, what I am asking is exhaust fan is sufficient or both exhaust and inlet fans are required
@@NagarajKS-eq3fp
In my case the bedroom is 10 x 10 and I am happy with single fan...
So it depends...
And I am using it to blow air from outside to inside to create positive pressure... I have tried to use it in reverse way to create negative pressure however effectiveness was very less
Thanks
You are most welcome 😊🙏
One suggestion if you don't mind Exhaust fan more beneficial at top of window, as per scientific fact hot air at high level 🙏🙏🙏
Yes, you are right.
I fitted it at various places...
Finally settled at the shown area, that is at bottom of the window, because that throws cold air directly on my bed so feel very much comfortable.
Due to this location, even in April I have not used my AC which is big achievement 🙋😊
If I'm not wrong, this process is more about taking cold air inside than getting hot air out through ventilation. For ventilation as sir said it needs additional fans in the room for that.
@@mrpersonal1326 as of now for me single fan is working fine 😊
Exactly!
@@TrekBookIndia hi sir we use symphony air cooler in summer but humidity it produces is irritating only body part which gets air in directly from cooler will be cool and other body part will be full of sweat, to remove this humidity suggest me an exhaust fan with high efficiency no noise, low power consumption, and please tell me whether metal or plastic fan is best?
Sir, when the display of the fan is like it should be fitted with blades inward.. after seeing your video i was able to know that it is effective if it could be done other way also with effective ness.. one question is that are the plastic blade fans lasting long when we operate them for 10 hours in the night
Yes, plastic fans are also durae👍
Sir ek bat batao single room hai aour uper ke wall pe exoust fan lagaya hai cooler b chalu hai to sab darwaje aour kidki band raku kya ya fir kula raku darwaje room tanda rakne k liye aour jaha cooler laga hai usi k uper exaoust fan laga hai to work karega n please reply sir
You can close the room door and keep exhaust fan for throwing air out
My understanding only: One important point is hot air is always near ceiling so we need to remove that air. So exhaust fan should be as up as possible. Here again depends upon room size you should increase power of exhaust fan.
Yes, you are right 👍
Hi sir,Im one of your new subscriber.Its a good experiment video.Sir, is this experiment controls (or) maintains humidity also na sir??
It can't control humidity, but surely will not reduce it...
Like when you use AC then humidity in room reduces too much since AC pulls out moisture from air... Here fan continuously pushes fresh air inside room so will not reduce humidity
@@TrekBookIndia ok sir thank you.I understood.🙂
Very very nice thought sir.....👍 I appreciate your efforts....i also observed this phenomenon and was about to experiment it...but luckily found your video on internet....these temprature difference are reversed in winters....i want to ask in which month you did this process and your city
@@adityapanwar4840 I have done this experiment in May in Pune city. Last 3 years using the idea successfully reducing my electricity bills 😊👍
@@TrekBookIndia commendable job sir👏 these little initiatives will make change one day
@@adityapanwar4840 yes 😊👍
For same window can we put one fan for inflow in the bottom and one on the top for outflor
It may not be that effective
What about setting an exhaust fan in another room of the floor to blow outside, and the one in the bedroom (as shown in the video) to blow inside. Will it pull more cool air inside? What is your opinion on this ?
Yes, but the rooms must be interconnected to each other without any leakage path
We had high ceiling house which had split roof, the lower roof was below the line of the ceiling exhaust. The previous tenant who lived in the house had blocked off those ceiling out of fear of theft. But when we moved in, my father being an engineer got those blockages removed and installed those water coolers. The result was, our house became very cold upon running those coolers even in the middle of the UttarPradesh summer 🙂
Very good result 👍😊 thank you so much for sharing your experience with us and viewers 🙏
@@TrekBookIndia any idea to reduce afternoon temprature?
@@Mahesha999 heat reflective painting on roof is highly effective way. Also exterior wall should be white painted

Great experiment, correct me if I'm wrong , agar hum koi heavy desert cooler andhar window ke pas lagake, exhaust ko andhar ki humidity bahar keechne keliye lagathe tho aur phayada hogi ? Mei ye experiment karna chahthahooo
Yes, for sure it will help 👍
Namaskar Uncle ji. 4 wing fan or 3 wing fan iron wala lu. confused hu. Plastic wala sahi ya iron wala and which brand. Mera room 12*20 hai and only windows hai.
4 wings plastic fan is good since it throws more air and makes less noise compared to the metal fan
I have tried both metal and plastic
Check for product link in video description, it's the same fan I am using... You can go for same brand bigger size fan
I have also don some experiment.... So i would say u should fix the exhaust fan up of your window coz hot air is more liter then the cold ❄ air weight... Hot 🔥 air alway go upside nd cold ❄ air down side coz cold air is very dance... I will work effectively more if u fix in ventilator.
Yes.. I have tried different locations... And although this location is technically wrong, practically it throws cold air directly on the bed giving comfortable sleep and hence finalize 😊🙋
Thanks a lot Sir. What's the brand for temperature sensors ? Are these available online ?
Yes, available online for very low prices
amzn.to/3E1TQcq
Very good experiment.. Just wanted to know,
will it not help better to reduce temperature, running fan in opposite direction due to passive cooling ( Thermodynamics)
I tried that...
Problem is that room temperature is high and outside temperature is low, so we are driving hot air out from room, but then since the bedroom is big it's unable to cool the room effectively.
Also having fan driving air inside brings low temperature air (almost 5 deg low) directly on bed which creates comfort while sleeping.
These are practical observations... Being a mechanical engineer and worked so many years in R&D I have always experienced difference in theory and actual feel.... I am not sure if I am able to convey you... But for me the inward direction worked good 😊🙋
I appreciate your scientific approach.
@@nitinsharma3934 thank you so much for your appreciation and support 😊🙏

That's why purane deno ke ghar mai ventilator reheta tha taki celling fan baharka hawa andar khiche...ek doubt hai is experiment Mai celling fan agar chalega to is chotese exhaust fan ka hawa utna useful nehi hoga sayad.. celling fan ka hawa celling se niche ki taraf ake khirse bhar janeki kosis karega tab exhaust ka hawa resist hoga..agar exhaust fan celling fan ka jo rod hai us distance Mai kisi bhi wall Mai laga hua hoga to cool air or jaldi andar ayega..but apke effect ke lie ek like to banta hai
Exhaust fan plus ceiling fan also works better
Sir Will it work in 45+ C in Pakistan? 😒 Raat 10 baje bhi 37/38 hota bahir minimum 32 ja raha
u can use bathroom fan ceiling mount in corner with pipe outlet outside.
Thank you for your suggestion .. as on now I am still using the temporary arrangement done at the time of experiment and it is working well .. so I will do in proper way soon 🙂
scientist WOW
😊🙏
Interesting hack!
I have a question for you here pls, I have a room which has very good AC flow coming in, I plan to make a gypsum partition up till the ceiling with sound proof partition walls; however this will ideally block the ventilation... Will it work that if I put an exhaust to both sides of the walls aligned; so from one room cooling will pass to the room with no ventilation because of the partition? Also, will it be the same cooling temp as the room with no divider? and what if I put 2-3 exhausts on each side to let the air flow in?
looking forward to your reply; thanks in advance!
You will need 2 exhaust fans fitted in such a way that one fan throws AC air in partition room which is at lower height and other fan which takes back warm air from portioned room back to the AC room for cooling
Alternatively you can try to use only one fan to push cold air in partioned toom and keep big hole in partition top which will push warm air back to AC room.
@@TrekBookIndia thank you. Lemme try.
Cheers!
Thank you for this.. But I hope you'll add English translation.

sharing my hostel experience here
We (I and my friend) bought a cooler and exhaust fan
our beds were in parallel and had around 1.5 feet of gap
we placed the cooler there in swing mode
and the exhaust fan hanged on the window
(except the window where fan was hanged all doors and windows were closed)
believe me that was the total chilling sleeps
location: Gwalior
Great to know your experience 😊 it Wii surely help other hostelites 🔮
