dpmiller Posted October 8, 2021 Share Posted October 8, 2021 I went with a Samsung F/F a few months back with an inverter. While it's certainly not silent, it makes a different selection of noises to an old-fashioned refrigeration unit. There are no sudden clunk/hums as the compressor starts, but as the compressor is variable-speed the hum ramps up and down markedly. Anecdotally, the more modern refrigerants seem to make more noise as they make their way around the innards of the appliance, and frost-free means you're going to have one or more fans whirring away inside...

How could I reduce the noise of fridge freezer's compressor (while keeping the back of the fridge ventilated of course)? Ideas: A short stud wall section beside the fridge freezer? Sound-absorbent foam behind Any better ideas? (By the way, ignore the kitchen design. Its just a rough draft.) Not to sound cheeky, but, is it older and or a more budget model? Maybe not, maybe it is just noisy. I would say most fridges/freezers now are more or less silent... Linear compressor models are usually quiet.

Ish... I don't know if any domestic refrgeration has anything other than a piston compressor, and they're all "hermetic", that's the metal can it's sitting in...

We have 3 at work, one is very quiet (Bush), one is just a basic, cheap, domestic one and seems quiet enough. (Currys) The bigger, posh fridge, is very noisy, but it is about 12 years old now (Liebherr). Link to comment Share on other sites More sharing options...
dpmiller Posted October 8, 2021 Share Posted October 8, 2021 The Liebherr probably needs a new fan, if it's sitting up on top of the unit... Link to comment Share on other sites More sharing options...

It every now and again, makes a deep rumbling noise. I do wish they would put an air release valve on the door so you don't have to wait wait 30 seconds to open if after shutting it.

Dreadnaught Posted October 8, 2021 Author Share Posted October 8, 2021 My fridge will be in the open plan living room/kitchen, under the kitchen island. It will be a larder fridge only; the freezer will be in the utility room. I am now planning to surround the back of the fridge with sound-absorbant foam panels. I got the idea from @ProDave. And I will buy a decent fridge with a low decibel rating. It is helpful that all appliances now have a decibel rating (although I am not sure how definitive are the figures). I know that even quite noises can become intrusive in a well-insulated airtight house as the background noise levels are so much lower, but hopefully these measures will do the trick.

I'm sure you're aware of this, but for the avoidance of any doubt (and for anyone coming along later who doesn't know), the insulation is put onto the surfaces of the walls around the fridge, not on the fridge itself. A decent gap is needed between the insulation and the fridge to allow airflow to take the heat away. 1 Link to comment Share on other sites More sharing options...
dpmiller Posted October 8, 2021 Share Posted October 8, 2021 ...and under, as well. most fridges are pretty open underneath and a nice reflective tiled floor will cause issues for sure. 1 Link to comment Share on other sites More sharing options...
Pocster Posted October 8, 2021 Share Posted October 8, 2021 Fridges can make a lot of noise . I find if you fill them with wine they are a lot quieter Link to comment Share on other sites More sharing options...
