Covering vents when changing from absorption to compressor fridge.

[mike.lamb]

Just ordered a Dometic compressor fridge to replace our absorption fridge. Any good approaches for covering the vents?

Thanks

Weve covered the vent for our grill as we never use it. I used a piece of kingspan insulation slightly bigger than the hole put the vent cover on and cable tied it from the outside. Its easy to remove and cuts draughts down a lot

the fridge will work better with the vents left in place

I'd put a digital thermometer sensor on the liquid line (that's the condenser exit where the dryer is) it's OK if it's warm but if it gets hot it will reduce the life of the compressor as well as use more electric.

That's interesting.
What sort of temperature range should I be looking for?

It's not set in stone, it varies. For instance when you put something warm in the fridge or it's pulling down from being first switched on it can be quite warm and that's normal.
You'll know when it's too warm. In the past I've worked on thousands of fridges and sometimes you can burn yourself on the liquid line that's usually when the condenser is blocked or the fan fails though.

I'd probably not want it to go above 40°c in the summer when cycling normally.

Thanks for that. I have a fan, which I up-spec'd a few years ago it is behind the condenser. There is little or no moving air behind the fridge. It would be interesting to monitor the temperature.
Swift have positioned a vent panel above the rear of the fridge, but it is in the bottom of the wardrobe, so difficult to keep clear at all times.
The next time I drag the fridge out I will position a temperature sensor and see what readings I get.
Anything to make it more efficient and save some amps.
