Gas fridges

[AngusMcDoon]

How do gas fridges work, i.e. the physics of it. How can what I presume is a flame produce cold?

See here for starters....

That site and its links says it all. Now I know. Thanks.

Apart from the safety aspect..is there a reason why Gas fridges are not used on boats??

They don't like working at an angle from memory +/-10 degrees.Mate of mine converted one to run using a paraffin primus as heat source not a great success as thermo control was a bit of a problem.

They do not work unless nearly level, so only usable at anchor/moored. Other than that they work great and use very little gas. Wouldn't be without mine (a small stand-alone chest type; also works on 12v and 240v).

I dont have any trouble using my gas fridge even when close hauled - makes quite good ice as well. /forums/images/graemlins/laugh.gif


Multihulls are great!

Oh! So that's the advantage of multihulls ..... always wondered /forums/images/graemlins/grin.gif

Does yours work on gas only, i.e. no 12 or 240 supply at all, or if running on gas does it still need electrons for other less power consuming stuff, like fans and control?

how are they plumbed in. presumably they need a dedicated air supply and exhaust?? how are theyviewed by insurance companies

Angus,

Mine will run independently on gas, 12v, or 240v.
On gas, no sort of electrical power is needed. It has flame-failure detection, but you light it with a match. Newer models probably have piezo ignition.
On 12v, consumtion is about 5amps, so only really viable when engine running.
On 240v (only), it has thermostatic control like any normal fridge.

A similar model is currently advertised in PBO as the 'combicool' .

Main plumbing in is the gas line. Mine is not connected for either 12v or 240v. Although 22 years old, it still has piezzo ignition. No air supply required. preferably a flue connection to the outside for the combustion products unless you like carbon monoxide!

Thanks for the reply and information. I really should have given the original post a NB icon, because although they are used on boats and therefore can be counted as boaty equipment, my intended application is not for marine use at all. /forums/images/graemlins/blush.gif

I own a house in the far North of Scotland. It has no electricity supply, and up to now, no fridge. Full size gas fridges are rather expensive (£350-500), but I was considering a 30-40 litre chest type as used on some boats. These seem to be available for about £140. 40 litres would be fine for me by myself for a few days. But to use one of these, it needs to be completely independent of electricity, even 12 Volts. Sound like one would suit my purpose.

I have a gas fridge on my boat and it works a treat.
