How to reduce noise from a small under-the-counter fridge?


Garald

Recommended Posts

(still a part of the house-renovation saga...)

 

There is a space in the ground-floor (not so small: about 14m²; former laundry room + a broken toilet I bought from the coop) that we are turning into an independent studio of sorts; it will be my GF's home office when she is around, and my parents' room when they visit. Of course we'd like to install a (tiny) kitchenette, but we'd like it to be quiet.

 

It is not hard to find an under-the-counter fridge having a noise level of 38dB or even 36dB in the technical specifications. (As to whether those are necessarily correct or tell the full story, well...)

 

What can one do in order to bring the noise level further down, without, of course, keeping the fridge from working?

One obviously can't put the fridge in an airtight enclosure.

 

The fridge's back will go against an internal wall, with a WC/shower room on the other side.

If it only needs to be small, how about a caravan style evaporator fridge, totally silent, no compressor.

 

Example? (Google hasn't helped me.) You mean, one like this one? https://m.darty.com/m/achat/gros_electromenager/refrigerateurs/refrigerateur_bar/klarstein_refrigerateur_a_boissons_silent_cool_mini_frigo_mini_bar_silencieux_30l_classe_a_noir__MK619385856.html?dartycid=sea_shopping-marketplace-online_MP-PLA-Occasion-GEM_New_adgroup_GEM-Occasion&gclid=Cj0KCQiAt66eBhCnARIsAKf3ZNEO5Y5T7qiCroh8osYtOIQGkqSg-VasQgfMel4ujaOK39wIxx6yiScaAhotEALw_wcB&esl-k=sem-google|ng|c630963354220|m|kpla1789486426955|p|t|dm|a142860815236|g18718261849&gclsrc=aw.ds&ofmp=91691492

 

Odd how it uses more power than many fridges with twice its height and several times its volume - is that a common feature?

Sorry the term I should have used is Absorption Fridge.

 

This is how they work: https://en.wikipedia.org/wiki/Absorption_refrigerator

 

They are less efficient than a compressor fridge, but silent in operation.

 

They are common in caravans as the heat source to make it work can be gas, 12V or 240V electricity so very versatile.

 

Here is a 240V one designed for silent domestic applications https://www.amazon.co.uk/Barcool-Bar40-LED-Bedrooms-Guesthouses/dp/B0875NVX17/ref=sr_1_11?keywords=absorption+fridge&qid=1674297318&s=appliances&sr=1-11

(Is that the same as what some manufacturers call "thermoelectric cooling"?)

Yes, that's the rub, they seem to use more energy than much larger under-the-counter fridges. The one you linked to (40L) uses 162kWh/year (and says it is the quietest in the market), the one I linked to uses 125kWh/year (it is 30L as opposed to 40L; funny how the vendor sells it as "pour les célibataires"). The best energy rating I've been able to find is F, for this one: https://www.amazon.de/-/en/gp/product/B07L6D9F1J/ref=ask_ql_qh_dp_hza?th=1

 

There also seem to be some very quiet (23dB) compressor fridges, but the one I've found (Klarstein Happy Hour minibar) seems to have even worse energy consumption, to judge from comments online (I can't even seem to get precise energy-consumption information from the manufacturer's website - surely a bad sign).

We have an old fridge at work made by Bush that is so quiet I may swap it for my one at home.

Just did two sound readings, one with it not running, and one with it runnin. 1 meter away. The spike on the first one (not running) is me breathing.

 

Not running

Can you tell us the model?

My one at home, that I did the sound test on, was the cheapest from Currys.

The Bush one at work is probably 15 years old, no idea what model it is, looks similar to this one though.
