I don't really know where to put this and I didn't want to start a new thread, so there it goes.

I stumbled upon an article about cooling fridge compressor by condensation drip from freezer coils.

https://www.sciencedirect.com/scienc...14157X17300813

I thought it would interest someone. They managed to loweer the consumption by nearly 10%

That is interesting it has me thinking could increase the gains by using a heat sink fitted compressor shell so it never gets hot in the first place increasing the cooling efficiency.

Ideally the hot air should be vented away from the fridge straight from the compressor and condenser

I once thought about using a small fan to blow air over the coils and/or compressor, but I guess the improved efficiency would hardly outweigh the fan's power consumption.

If you'd be able to start/stop the fan in sync with compressor running, it wouldn't consume as much as running nonstop. Also, depends on the fan

I had laptop cooling pad blowing air on coils, but it got dirty from dust and cat hair (stupid animals ). The consumption of whole system basically didn't change (the cooling pad ran of USB-outlet - like phone charger)

AFAIK virtually all modern (American) frost-free fridges/freezers dump the condensate to a drip pan with some condenser piping in said pan. this serves to mange condensate without a pump/drain, and also boosts the efficiency of the system (notwithstanding poorly managed evaporator defrost strategies).

but is said drip pan thermally connected to compressor/coils? Because mine was plastic with only 1cm squared direct connection to compressor, otherwise there was like 2mm air gap. So I removed the pan completely - even if something drips, it won't touch electric wiring, and I put different collector under the fridge, so nothing spill on the floor

for example:


i've also seen it where the tubing "U"s down into the drip pan area. i don't think they used to do it for added efficiency, i think it purely for condensate management.
