Could MotorVehicles' Cabin be cooled using the Heated Water cooling its ICE?

05/25/2008 5:01 AM

In another Forum (under Sustainable Engineering), the idea of using Heat to cool a Home Refrigerator has elicited good discussion. I would now like to generate some creative ideas on the same issue - as applied to Cars, et. al.

Water too heavy to be transported?

Refrigeration by the application of heat is usually accomplished using the absorption principle.

http://en.wikipedia.org/wiki/Gas-absorption_refrigerator

This operation depends on the extreme affinity of either ammonia or Lithium Bromide for water, which is very heavy. There are small absorption refrigerators for trailers and RV's that run on both electricity and LPG, but you would need a much greater capacity (and therefore more weight) to cool a vehicle.

There were gas refrigerators, where gas was the source of energy, and ammonia the refrigerant.

Ammonia, in the case of leaks, is very dangerous.

Perhaps somebody here will recall for us how they worked.

Do you want to crash a car that uses the absorption principle applications.

Most use some pretty nasty stuff - ammonia, etc.

Gosh, that's a nice idea. So we'll be working with heat transfer technically. I don't know. Probably we'll need to find a way to condense refrigerant some how here but just for the heck of it and brainstorming here a little I will say modestly that if we'll be able to let's say for example that we get the engine cooling system Glycol/Water solution and force through a heat transfer by pumping it around raising refrigerant temperature and circulate it in the refrigeration system loop we'll probably make it happen some how.

Now remember this are heat transfering no mixing solutions stuff, don't get me wrong now. The principle will be of the heat transfering basically and circulation of the engine Glycol/Water solution separate loop and the separate loop for the refrigerant apart. Since normally the refrigeration system is a heat transfer loop back and forward should not be too difficult to make it happen this way too. I don't know ! Heyyyy everything is possible some how. Hang in there here we go again,hehahaha!

Anyhow, we'll be need to make it circulate back and forward around to make heat transfer condition present for this purpose. Also, we'll going to need like some kind of vacumm pump onboard some how to reduce evaporation pressure to create the quick boiling condition of refrigerant at eveporator level.

Now, the extra tip, here we go..Oh Boy! Implementing solar cells collectors at roof top as a heat build up condition to backup incremental heat when needs it and cut some of the heat transfer unit workload by economizing workload at refrigerant transfer unit.

Not bad ahhhaeeh! This is just brainstorming here a little for fun-- "don't bring it to the bank yet",-- hehehahii.. I'm telling you is a lot of technology going on around latetly out there so we can even hook up such concept within sensors and electronics controls stuff into the onboard car computer and have some kind of new invention near future, Heyyy..Who Know's?

Crank that Puppy Up...

The many RV's have refrigerators that work just that way.

My RV's refrigerator will run on 12V, 120V, or propane. When using voltage it is an electric heater.

One kind of brainstorm I'm surprised not to see actively investigated involves ways, such as that car-top solar collector you speak of, to mitigate the "cost" of running automobile air conditioning. True, it's only an incremental improvement; but a very substantial one...and one which seems would be quite feasible of implementation in short order, whether as OEM or after market....

PS: Have you noticed as I have, how car windows are coming back open in more and more cars? And the ratio of single occupancy to multiple occupancy vehicles also seems to be rapidly diminishing. Perhaps the next big style enhancement will be the return of the wing window.

In looking for ways to capture waste heat from a stationary diesel-powered electrical generator, I have come across a couple of outfits, one in Colorado and one in Italy, that are doing some interesting things on commercial scales, but most of it seems to be developmental rather than commercial. I am out of town right now, so don't have access to my references, but try googling "waste heat recovery".

There are other possible media for absorption cycle- sulphur dioxide comes to mind, which was MUCH more dangerous than ammonia. There may be others that would work as well. The previous wiki reference is a good place to start.

It is possible, but is it economically feasible?

Hello manilaman

The Gas-absorption refrigerator is described here: http://en.wikipedia.org/wiki/Gas-absorption_refrigerator

This method of refrigeration is not very efficient.

Kind Regards....

Heeyy Sparky that one really seing very great and COOL for sure I will be checking that one out better since It does make it out. DONE COMPLETED. Definetly pal's I surrender you guys are PRO's. Lot to learn here at CR-4 Technology Mall Hehahehahii..OH Brotherrrr! Awesone Model rigth there. Nice Nite All Now Buddies...

I'm Freezeeeee,

Hi Ernie,

The problem is the weight, It's gonna be hard to match the efficency of an actual compressor system that uses r134, r22.... or some thing similar.

here's a link to a solar powered methanol/charcoal ice maker http://www.limsi.fr/Individu/mpons/solaradsor.htm

still you won't get the Kcal's per Kilo of added weight.

Thanks Garth. Frankly, I never thought of the need for a Compressor. What only caught my imagination was another Thread of using Heat for a Home Refrigerator. Hence, if this is possible, why not Cars et.al.

All sounds good so far... Heat transfer will be appying here some how. Uphill climbing so by moving heat against it's will will take care of it. There you go. Green Lite On Push That Pedal Now.
