Fridge Vent covers

Sadly the ASBO donkeys got shipped to Donkey borstal some time ago. We don't go to Flamborough at Christmas anymore though anyway. Feckers even ate the seat on my Peugeot Speedfight.

They're probably staring over my garden fence as we speak Barry. My next door neighbours take in rescue Donkey's and Goats.

Yeah behind a fence is where they belong! They were great entertainment. When behind the fence! The dark one Alfie was just a real naughty fecker. Michelle absolutely adored them.

13 years ago this.

Nuts ain't they! The Goats are just weird though they just stare at you with their heads cocked to one side and they have evil eyes.

Every now and then though we hear the Donkeys fart - oh my fekkin God, I've never heard the like! Puts me right off me BBQ.

Oddly I don't ever remember having cooling issues in Hank 1 without fridge vents when on EHU or wilding and we were down to some pretty low temperatures. -17c was the record I think. It was terribly insulated though. The drafts would blow through the gap around the fridge and through the cutlery drawer which got worse as the van got older. The only issues we had with the fridge cooling was when it got above 30c.

We had terrible problems with the old vans fridge though. Every year the jets would get blocked with muck and rust. Im hoping getting some proper covers will help avoid this down the line.

1) Cling film. Cost: zero (to the nearest penny). Availability: In your kitchen. Don't forget to ask permission first!
2) The fridge uses so little gas that covering up the vents will not make any difference to it working or not. The fridge does not take any significant air from the vents, it usually takes its combustion air from the habitation area ventilation. It does not emit carbon monoxide from burnt gases into the habitation area.
3) Personally I can't work out why these vent covers are supposed to make the fridge work better. I thought that Newtons law of cooling said that heat lost from inside of fridge = heat gained by outside air. Or another way of putting it is that the greater the temperature difference between two surfaces or bodies, the greater the heat transference. In other words if the fridge coils are at 60 degrees and the outside air is at 40 degrees, there will be less heat transfer and therefore less cooling inside the fridge than if the fridge coils are at 60 degrees and the outside air is at zero degrees.

4) the reason your jets get blocked every year with muck and rust isn't exactly to do with the fridge being old. The rust comes from the steel 'chimney' immediately above the flame which emits water vapour as well as the burnt gases. If you dismantle the chimney and burner and scrub out the inside with a wire bottle brush it should last several years before needing doing again. If the chimney is that badly corroded that it needs cleaning out every year, get a new chimney and flue assembly.

You couldn't do that on our old fridge or at least so I was told.

One things for sure the vents were probably useful on our old van as no way was the fridge sealed properly from the hab area so it probably was important it was ventilated when on gas. A couple of times when it was playing up it set off the CO2 alarm.
 
Actually. That post above about the flue got me thinking. Where is the fridge exhaust on this van? Do they go somewhere else now? Maybe up through the cooker extractor or something? I take it modern vans don't have a flue anymore?

I think the flue is just inside the top vent. I have a very vague recollection of the vent covers for this type of installation having a circular hole on the right hand side of the top vent . . . . . .
but I have been known to mis-remember things. Does that qualify me to be an MP?

Which might explain why someone said not to cover the top vent when on gas. This is good news then really as its the bloody flue that caused all the problems with the old van and old fridge. Ill be able to cover it up properly now in winter.
 
It's not much more than a pilot light anyway, only one very tiny hole that they call a burner too
