Thank you very much for the video. Can you please write the pressure and the temperature of Ammonia -Water, Ammonia, water in every stage in this cyrcle? Thank you again.
While this is pretty much correct, the terminology is a bit odd and it doesn't emphasize enough that this is really separated in a high pressure and a low pressure side (for example the water returning to the absorber needs to pass through a valve to make sure that the high pressure from the "generator" doesn't leak back into the low pressure side any more than is needed to move the water). The function of the water is to make getting the ammonia back to the high pressure side easier/possible (pumping an aqueous solution from low to high pressure is easier than compressing ammonia gas both energetically and practically). It also misses that the absorber acts as a heat sink and will need dump the heat from dissolving the ammonia, an exothermic reaction, because the cooler the water, the more ammonia it can dissolve. I'm not really sure, the names are odd to me, but it sounds a lot like the "analyzer" and " generator" is just a reflux distillation. I'm not sure what the "rectifier" is either, though it sounds like and extension of the reflux part of the distillation (also, why return the cooled ammonia-depleted water to the "generator" and not the absorber?). I'm not sure how the water that is getting returned to the absorber is getting separated from the ammonia at the bottom of the "generator". It may just be a simplification of draining the remaining water after most of the ammonia has boiled off. If so, then the "generator"/absorber would need to work in cycles and not continuously. In which case a system would need to be sized to run a single long cycle during the daylight hours to make maximal use of the solar energy. To use this as a system to actively cool things down during the same hours that the "generator" is working you would almost have to add additional storage for ammonia depleted water and high pressure liquid ammonia.
Rewatching this, it does seem that the "generator", analyzer and rectifier is just a reflux distillation with the reflux being collected and sent back to the absorber. This could be done continuously. Though I think large efficiency gains could be achieved by running this on a daily cycle and using storage tanks for the water and ammonia. This way you could have cooling capacity even when there isn't any solar input and you wouldn't have to continually pump the liquid into a pressurized generator but rather pump the ammonia enriched water at night when the "generator" can be cooled down and equalized for pressure.
@@siggyincr7447 sir we are thinking of making this setup as our final year project in mechanical engineering, so please assist us a bit how can we start, and how much will it cost us doing this in Pakistan?
Thank you this is great content. I have some questions, however. Is the pump turned on by the solar energy supplied at the generator or electricity? What is the nature of that solar energy? Is it electricity produced by a photovoltaic panel? Or it is merely solar radiation?
The solar energy to the "generator" is in the form of heat. This can be a simple tube coiled inside an insulated box . A Low E window allows light to come in and keeps the heat from escaping. It will heat up like a car sitting in the sun. Only 50-60deg C is needed. The pump will need to have electricity from either the power grid or a photovoltaic cells and battery system. However, the power needed to pump the ammonia-water solution is very small compared to what a normal AC unit will use. Most of the power to do the cooling will be from the solar heat.
@@alshaikh7 I have not seen too many companies making them as room sized or building sized air conditioners. They are usually used made for small refrigerators in RV campers. However, I am considering making one for my shed. If it works well, I would like to commercialize it. I have several ideas for their uses.
I'm 4th year mechanical engineering student, I'm thinking of making this idea as my fyp so please tell me how much will it cost the whole apparatus and also its design and fabrication in Pakistan?
From my understanding solar energy is used for both driving the motor through a PV cell, and for the heating up the so-called generator which causes the ammonia water mixture to evaporate where I can be separated and sent down it's respective routes

Excellent ! It s the first time I understand all this cycle ! I perhaps watched more than 10 videos about this subject ! Thank's a lot !!!!
It is best video on this topic i have seen so far.
thank you!!this was helpful..please make similar type video on solar adsorption refrigiration system
Very useful information
You've done it again.. Well explained.
Thank you very much for the video. Can you please write the pressure and the temperature of Ammonia -Water, Ammonia, water in every stage in this cyrcle? Thank you again.
Very helpful.
Make videos more
Thanks, I needed information.
Definitely can't use copper in this system lol. I definitely want to try to make my own in the future. Looks like a fun project.

I want to video topic,, solar energy system air conditioner

So the function of solar energy here was just to pump the water from absorber to generator... Correct me if I'm wrong
From my understanding solar energy is used for both driving the motor through a PV cell, and for the heating up the so-called generator which causes the ammonia water mixture to evaporate where I can be separated and sent down it's respective routes
I am looking for a supplier of such test rig. Probably with some slight modifications.
analyzer is used to allow the ammonia vapor alone , so what is use of rectifier
excellent
Thankuuuuuuu ♥️♥️♥️♥️♥️
Keep it up Guys ❤️
hi
where i can get blue print of such cooling system? i want to build such system. what should i do ?
We are interested to do this project which company doing this project if you have share the details.
Please ask a refrigeràtion engineer for the names of things....
Ammonia was not safe when its leak ?
Wait, why do we need the water?
For absorbing ammonia vapours
@@MechanicalGuy but it is the ammonia that mediates the heat exchanging

absorption ?

@@tomcantrell5553 now what is analyzer formed of? and rectifier separator also ?
@@hanahisham8022 I think either 316 or 304 stainless-steel are good choices for those components
why do you need water?
Water as NH3 absorption
