Constructing a thermal referigerator for home use.

05/03/2008 11:07 PM

I live in Mysore South India. I have fabricated a parabolic cooker which I use 300 days in a year to cook, meals, fry and bake my daily meals and also to make hot water. I would like to make a thermal referigerator. I have been hunting for practical design to help in its construction but have not been successful. Ideas,leads and suggestion will be thankfully accepted and appreciated.

Dear Chandu,

You need some batteries, and a Stirling engine to run from your steam (pressure cooker). Solartron, has low draw machines like refrigerators. (Iceboxes) Just an Engineer in Australia may be able to help.

The referigerator I want to make does not require electricity. It uses heat and to vaporise liquid ammonia which then brings about cooling by means of a condenser. When I was a small kid in the late 1940,s we had an elecrolux which operated on heat produced by a kersene heater at the bottom.

Can you give me more information about the Australian Engineer so that I can contact him. Thaks

Those Electrolux refrigerators worked on what is known as a absorption refregeration cycle. The principle is well known, but I don't know if you can build it yourself. Though it has the advantage of having no moving parts it is not efficient. Of course with solar energy that may not be an issue. I am very interested in what you are doing, and would like to visit you at Mysore if possible. I am at Trivandrum, Kerala.

You can experiment with the available electro lux refrigerator which works on Vapour Absorption principle by replacing electrical heater provided with either hot water or steam you can have a look at the electro lux refrigerator at most of the five star hotel rooms to keep a bottle of water and soft drinks chilled good luck

Please place the pictures in the blog, if you do not know how to do this then send me them via email and I will do it for you. Its very easy, you need to have the pictures in .jpg form in a folder on your PC, then you click on the camera in the tool bar above and tell it where each picture is separately.

If you are unable to do this for any reason, the just send me an email first via CR4 email service and then I will send my private email address separately to you personally, please do not publish in any way!!

Simple and it works!

I guess for longer cooking periods you turn it to face the sun from time to time too....

Thanks for the picture.

I have developed a tracker with a small car wiper motor which follows the sun with a timer in the circuit. This overcomes constant manual ajustments which in the tropics is quite a sweaty job.

Pretty good. You may have something you can in India there....I am sure many people would like to not have to buy bottled gas all the time....or search for something to burn....

Hi,

There are many refrigerators that operate on heat energy, do not build by yourself.

Most have a household gas-bottle and a burner as heat generator and this you can replace by some solar concentrator - should be only a small problem for you.

And: as A.G. asked for: please fotos and drawing of your cooke!

Most RVs and Motor homes have a refrig that works off the propane tank. You could start there and replace the flame with your solar cooker.

Re: Constructing a thermal referigerator for home use.

05/06/2008 7:45 PM

The adsorption refrigerator mentioned above works on a precise mixture of water, ammonia and hydrogen. They have no moving parts and last a long time. They consist of a generator (where the heat is applied), a condenser (where the energy is rejected), a evaporator (where energy from the product is picked up), and an absorber where the mixture comes back together. As long as you can boil water this system will work for you. The technology for this is fairly old and there should be more information out there somewhere. A redesign will probably be required as the generators used in the small refrigerator's require an intense heat source; such as a gas flame or electric element. There are thousands of this applications world wide. Where I am at the University of Toronto (Mississauga Campus), we are using waste heat from four gas turbine generators to operate a 250 Ton adsorption chiller for air Conditioning.

Good luck on your thinking outside of the box.

I think the word "250 Ton adsorption chiller " is an error and should be "250 Ton vapour absorption chiller ".

in India M/s Thermex india is the manufacturer based in Pune Maharashtra near Mumbi.and Brod chillers USA is another manafacturer i know and has used the machine.How ever if you have lot of waste heat its worth going for these chillers even though these chillers doesn't use electrical power you need to provide some amount of electrical energy to operate auxiliary equipment and needs lot of maintenance as the metallurgy used is cheaper and corrosion of internal parts is expensive in terms of downtime.Only trane USA manufactures the entire machine with Titanium and cost of chiller makes it unusable you need to be careful while choosing the VAM chillers.

Dear crm

we dont have waste heat , but we have dry straw , and some used oils , so these can be used as fuel to produce hot water and or steam , and electricity cost in here is very high , particulary when the consumption is for industrial plant , so i believe it worth it provided that the cost of the system producing cold water " chiller " and electric power, as whole is reasonable .

please advice

for further details please contact .

Re: Constructing a thermal referigerator for home use.

05/08/2008 1:05 AM

One of the earliest refrigerators to be manufactured was the famous "Electrolux" refrigerator , also nicknamed as the ' flame which freezes". Our family had one imported from U.K. in the 1950s. It had a kerosene tank with a wick which burnt continuously creating cold. Its principle of operation was based on the partial vapour pressure of H2 and NH3.In my college days (1964) I was knowing the theory thoroughly.But now, I am not able to explain it in detail.However, this is well described in the book on Heat Engines , then published by the ELBS(english language book society).

Another type of refrigerators which are now widely used in industry is the vapour absorption chillers , which use thermal heat (waste heat)to produce cold. Hitachi chillers in industry are very common.

I hope, from these leads, you may be able to make a working prototype refrigerator utilising the solar energy as the source of heat energy input to create cold.

- S. Saran

industry work on this principle , and use wast heat effectively for refrigeration.

There are a number of manufacturers in India who can supply the equipment for your need.But more information is required from your side to short list the manufacturers who will be suitable for you. Is it required for an industry or an individual ?. What will be the source of heat to be generated to use for cooling process like oil, electricity, solar etc. What is to be cooled and the quantity? Storage facilities of the cooled material? Appropriate Investment budget to be taken into consideration. Against these information a suitable supplier can be short listed for negotiation and finalisation. Let me know if you need more information or suggestion to help you in taking a decision for Indian equipment of high quality standards. Please contact me on this email id: ckusbd@gmail.com

Dear Mr Hasan Kashani,

The refrigeration system has to be designed taking into account the kind , quantity and source of heat. Please contact any supplier of vapour absorption chillers in your country or HITACHI, Japan.

Please let me know after you have successfully installed one!

Dear saran 369

in reply to your question

the quantity and kind of heat . : the heat is heat , we can produce hot water , steam of any pressure , so we cool water and run the turbine . it is not for home cooling or home refregeration , it is for industrial purpose

If indeed Heat could be used to cool the home, could not the same idea apply to moving vehicles - Cars, et.al.? Could Water as coolant for Internal Combustion Engines likewise be used to cool the inside of Cars, et.al?

Re: Constructing a thermal referigerator for home use.

06/22/2008 2:46 PM

Synopsis: use Stirling engines 'back to back' - some to collect energy, and fewer to
'chill' a well insulated ice box/refrigerator/freezer.

When I first read this thread, I was thinking that the small scale refrigerators like my parents used in the 1920/30's in west Texas where they grew up would be best. Others suggested similar situations. Commercial Ice houses have used amonia absorbtion cycle freesers for years. But the small scale ones have fallen out of favor, probably due to the toxicity of amonia and litigation costs (in the USA anyway). It is more efficent cycle than most others.

But if you can build 'a few' 'medium size' Stirling engines (not the low delta-T variety), and use one or two to generate power to 'drive' a 'cooling engine'. The cooling engine is just another Stirling engine. But if you DRIVE a Stirling Engine you can get SIGNIFICANT cooling from it. I have seen video on the internet (sorry, no URL) of it cooling and getting liquid nitrogen from air (it was dripping from what would otherwise be the 'hot end'). You don't have to drive it that hard, but you could generate a freezer/refrigerator with it.

I just purchased a book on generating a 5HP Stirling Engine (done mainly in Pakastan I think) that was pretty impressive. Evidently people have tried to go 'commercial' with it, but economics seems to happen to this venture as well as many others.

You don't need that much power. Especially if your cooler is WELL INSULATED.

In the USA, many coolers/refrigerators have under 1" of expanded polystyrene / styrofoam type insulation. Put in 4 or 5" (10 to 15CM) sealed well, and you don't need 'much' cooling. Also, in any 'freezing' area, keep a block of ice in there to give a 'cool mass' to help moderate the thermal changes and make it easier to keep the entire system cooler.

Old Ice Houses in the USA even those that used Amonia Cycle coolers eventually got the ground below them frozen for several feet. (many were effectively large insulated warehouses with the insulation going down several feet into the ground, so the ground underneath froze) I heard of some where it took a year or so after the Ice House was removed for the gound to un freeze. ... That was a LARGE thermal mass.

Best of luck. ... Jack

This is where I purchased mine recently. Paperback. I could not find it on Amazon.com

No affiliation other than happy customer. -- This book is a 'technical story' of the design, problems and development of this engine. The drawings in the book are NOT the last ones done, but apparently the last ones available to the author. The 'story' is the first 2/3 of the book, and the last third are drawings of parts and the assembled mechanism. Do not expect the drawings to be enough to 'just build it', but with some work and understanding it is quite doable.

The engine suggested is a gamma type (displacer and power piston in the same piston sleeve. The initial design was not a Rhombic drive, but the author suggests this as a 'good thing', where the simplification of some things overcomes the additonal mechanical complexity.

Please let us know if you construct one! (or more!)

This engine (or a similar 'cousin') was marketed as the ST-5 in the USA with some minor success, but is no longer available.

IMHO, the market several years ago may not have supported this product, but the market today might. Especially if it could be built from more off the shelf components and reduced/minimal custom component construction.
