Lithium Bromide Refrigeration System, LiBr refrigeration system

[@lelowijnands]

Perfectly explained, you know when someone has knowledge and talent when they describe things with simple drawings! Thank you so much, greetings from the Netherlands

[@overunityinventor]

Tenacity is everything, I read many texts and watched many videos to understand absorption refrigeration system, however I couldn't comprehend the complexity of the topic, but I didn't stop and kept referring to new resources and I finally found your video. Now I understand the concept. Thanks for the nice explanation.

[@palashdas823]

This is very helpful to essay understanding. Thanks a Lot ,Sir.

[@wfpnknw32]

fantastic explanation, honestly so much more intuitive than other explanations.

[@mellis966]

Thank you for the very clear lecture and for the explanation of how Li-Br pulls the water into itself.

[@tariganter6238]

Thanks for your very useful and easily informative video. I hope you would provide info on the following: Wasting Car Radiators Heat Instead of Using it for Air-conditioning Vapor cyclic refrigeration methods and systems are either 1. Vapor-compression refrigeration; 2. Vapor-absorption refrigeration (no compressor); or 3. Vapor-adsorption refrigeration (no compressor) In adsorption refrigeration, the refrigerant or adsorbate vapour molecules adsorb onto the surface of a solid instead of dissolving into a liquid. While in an absorption system, an absorber absorbs the refrigerant vapour into a liquid. Adsorption refrigeration also includes a generation process where refrigerant vapour molecules desorb from the solid. A variant of Vapor-absorption refrigeration is the Electrolux Refrigeration is also known as Domestic Eloctolux refrigeration or sometimes known as Three fluid Refrigeration as it uses three fluids for the cooling process which are ammonia, water and hydrogen. Hydrogen gas is used to increase the rate of evaporation and hence rate of cooling. No pump or compressor is used. The absorption cycle is similar to the compression cycle, except for the method of raising the pressure of the refrigerant vapor. In the absorption system, the compressor is replaced by an absorber which dissolves the refrigerant in a suitable liquid, a liquid pump which raises the pressure and a generator which, on heat addition, drives off the refrigerant vapor from the high-pressure liquid. Some work is needed by the liquid pump but, for a given quantity of refrigerant, it is much smaller than needed by the compressor in the vapor compression cycle. In an absorption refrigerator, a suitable combination of refrigerant and absorbent is used. The most common combinations are ammonia (refrigerant) with water (absorbent), and water (refrigerant) with lithium bromide (absorbent). Adsorption refrigeration was invented by Michael Faraday in 1821, even though the basis of artificial modern refrigeration dates back to 1748 with William Cullen experiments. Adsorption refrigeration technology has been extensively researched in recent 30 years because the operation of an adsorption refrigeration system is often noiseless, non-corrosive and environment friendly. In the early years of the twentieth century, the vapor absorption cycle using water-ammonia systems or LiBr-water was popular and widely used, but after the development of the vapor compression cycle it lost much of its importance because of its low coefficient of performance (about one fifth of that of the vapor compression cycle). Absorption refrigerators are a popular alternative to regular compressor refrigerators where electricity is unreliable, costly, or unavailable, where noise from the compressor is problematic, or where surplus heat is available (e.g., from turbine exhausts or industrial processes, or from solar plants), and in recreational vehicles that carry LP gas. It is also used in industrial environments where plentiful waste heat overcomes its inefficiency. So, Why we Waste Car Radiators Heat Instead of Using it for Air-conditioning? The heat energy in car radiators could eliminate the need for compressors and be used in the generator process in Vapor-absorption or Vapor-adsorption systems for car air-conditioning. It is better to utilize cars engines surplus heat using adsorption/ absorption systems low efficiency rather than waste energy into air, and using more energy to run compressors. Not only the World wastes cars’ heat but also consumes huge energy in air-conditioning and refrigeration in too many countries having high solar heat by using compression refrigeration wp.me/p1OEJz-1LZ

[@Dr.AmitMandal]

Design, cost and effectiveness constrants

[@tariganter6238]

@@Dr.AmitMandal But the design is simple; the cost is definitely will not more than compressors and radiators; and surely there is no effectiveness in wasting heat by evaporation to air and use energy to run aircons. The most obvious part is using aircons on warm settings

[@piyush2019ranjan]

Incredible way of explanation!! 🙏🙏

[@SrLgaming95.]

u r the 19th wonder sir. handsoff

[@deepakgoregaonkar7142]

Very nicely explained

Bro u made it look Soo easy

[@shivaay3478]

Very effective explanation thank u

[@ramizahmed1718]

Thanks so much to make it such easy to understand.

[@ayushkaiwart2451]

Explained nicely .thankyou

[@ManojKumar-fe7bk]

I think the direction of pump showing inthe pic is incorrect.It should be from absorber to generator.After all video is good and helpful. Thank u..

[@neerajdhyani637]

wow simple explanation sir but can you tell how vacuum is made either by itself by condensing the vapours in heat exchanger or by a pump

[@Dr.AmitMandal]

By condensing

[@Sunilinta]

very clear ..thanks a lot....

[@quantumboy_]

OMG you my sir, are amazing...

[@Agyaani-ka-vigyaan]

Excellent

[@madhusudan7432]

Sir. Even though it is heat removal process,why heating at generator adding heat, or any method.?

[@Dr.AmitMandal]

To recover consumed LiBr

[@darkknight5428]

👏👏👏 Understandable..... Thank you sir!!

[@sujono3815]

In LiBr-water absorption refrigeration cycle the absorber & evaporator is low pressure, and generator & condensor is high pressure, but why the pump is flowing from generator to absorber.

[@yogeshkumar-tv2to]

Very very good video sir Weldone

[@m.kalaivanan1206]

நன்றி 🙏🙏🙏 Thank you so much sir🙏🙏🙏 Simple and neat explanation😄😄😄

[@abhinavdeshwar1097]

Thank You Sir! 😊😇🙌

[@GSWithRahul]

Awesome Lecture 👌😊

[@ashwinpathak]

can u tell me at what temp water gets absorbed and seperated by Li Br?

[@KarthiKeyan-nc7xn]

Super broo....nice lecture MY only suggestion to add animation so that it take less time to learn n more people see effectively

[@naveedahmadkhanniazi642]

Really thanks

[@AnkitGupta-tm8lw]

thank you sir, clearly explained

[@khanakbar9234]

Good job 👍

[@arpitkumarrai3863]

I have one doubt sir please explain in detail about eveporator temperature and pressure .

[@Dr.AmitMandal]

The temperature you want, find the stauration pressure by refrigerant table...thats it.

[@ashwinpathak]

what type of heat exchanger is used?

[@Dr.AmitMandal]

According to capacity and other parameters ...

[@ashwinpathak]

Amit Mandal can u make it brief for certain capacity and parameters following heat exchanger is used??

[@biswajitboruah6883]

THANKSGIVING

[@abhinavjain5499]

U r best

[@yashdesai8372]

Isn't it same as vapour absorption cycle? Here instead of NH3 we have water and instead of water we have LiBr solution. And why have we provided cooling load rather than refrigeration effect in evaporator?

[@Dr.AmitMandal]

Ya you have understood it properly.

[@bisheshkhanal_]

very nice video

[@Gaurav-pc7jz]

How can we provide cooling in condenser.... And why we can't use that cooling in direct in refrigerator😂😅

[@Dr.AmitMandal]

watch my lecture on vapor compression cycle, it will be clear...

[@kkbejoy]

Have u removed any videos of lithium bromide ?

[@Dr.AmitMandal]

Unlisted

[@lokeshvijayan6386]

sir where the refrigerating effect takes place??

[@Dr.AmitMandal]

Evaporator

[@RashidAli-zq4cn]

Sir agar picture environment me Rakha h toh water kese evaporate ho jata h kyuki atmospheric pressure par toh water 100c par boil hota h please ans sir

[@Dr.AmitMandal]

Review Principles of psychometry

[@lokeshvijayan6386]

sir but after refrigerating effect taken place the liquid gets converted into vapour(it absorbs latent heat from closed chamber) know!! but here water is directly entered in generator,upon the application of heat only the Li-Br solution gets disappear as vapour is directly entered into condensor and the Li-Br again comes to Absorbent... My question is how refrigerating effect taken in evaporator?? in the form of water??

[@ashwinpathak]

lokesh vijayan cooling load means, a hot fluid is passed which exchanges heat with water and water gets converted into low pressure vapour and hot fluid gets converted into cold fluid and liberated out

👍

[@ajith9619]

But my teacher told me there will not be expansion valve 😕

[@Dr.AmitMandal]

ya , actually the friction resistance of pipe can also act as as an obstacle or throttle valve. But if friction only cannot serve as throttle valve then a valve is needed. Technically throttling process is Present in both the cases.

[@jagadishpatra9916]

Sir ish video ko hindi mein banaya

[@spirodarios2]

good lesson but you talk too fast

[@Dr.AmitMandal]

Ok, you can slow down by settings on YT video
