I was wondering if anyone knows why the "old fashioned" back mounted
coil refrigerators were replaced with bottom mounted coils?

Back coil mounts didn't become as filthy nor did they need a fan to
blow air over them.

Just curious...

TIA!

perhaps they were more subject to damage?
and you have to move the fridge to clean them.

Actually they did collect dust, but the primary reason for moving them underneat
was to get the fridge closer to the wall. Looks better when the frige isn't
enclosed and keep things stored on top from getting pushed off the back.

Also, I have a fridge with the

too, get
dirty.

I suspect it was when self-defrosting units came to be. They need some place
to drain the water. The heat from the coils along with the fan works to
evaporate the water from the drain pan so you don't need a drain through the
floor.

That, and the elimination of the need for ventilation above the unit.

If I'm not mistaken, you can't "build in" a fridge with coils on the
back without providing gap above the unit for the heat to escape
through. That can be difficult if there are cabinets directly above
the fridge.

They made self-defrosting units for a long time with coils in the
back. The one I have now from mid 80s is made that way and I know
they were made in the 70's with auto defrost and coils too. Not sure
when the non-exposed coil units first appearerd, but I would guess
90's?

Definitely better, as you don't have to worry about the exposed coils
in back when moving it and it goes back close to flush.

But there's a down side.
Cleaning the under-fridge heat exchanger is a real pain.

I still have to pull out the fridge and unplug it..
Then, crawl on the floor,
remove half-dozen hex sheet-metal screws from the back cover.
( this exposes the fan and the coils ( sort of ) )
Lots of dust.... worse if you have a dog or cat
Squeeze the shop-vac hose into all the nooks and crannys.
Try not to bend, break or disconnect anything.
Replace access cover
Rassle fridge back in place, and plug it in.

How many average households will do this
once or twice a year ?

How many will have poor performance
or shorter appliance life due to clogged coils...

It was alot simpler when Momma could roll out the fridge,
run the vac hose over the ( exposed ) coils, and roll it back.

clogged heat

My best guess at this is because people are stupid, and don't read the
manufacturers recomendations which specify minimum distances around
the refrigerator (specifically to dissipate the heat). Sine they know
you are going to cram in a refrigerator that will take up nearly 100%
of the space available, they put it at the bottom so they can vent it
out the bottom front.

Back coil mounts didn't become as filthy nor did they need a fan to
blow air over them.

My theory: look at the volume occupied by a rear-mounted condenser with
the appropriate amount of air space behind the fridge (and above it as
well). That's a lot of volume that isn't storing anything cold. By
using a fan-cooled condenser, the refrigerator case can be about 3
inches deeper and a couple inches higher and still fit into the same
space without projecting any further into the room. That gives a
significant increase in inside room if the box insulation remains the
same thickness, or allows thicker insulation (for better efficiency)
while keeping the interior volume the same.

no doubt the current style is at least a bit cheaper to build
manufacturers will do anything to save a dime multiplied by millions
it makes big bucks

I have one refrigerator where the coils are horizontal and stacked. That special brush will get between them.

But my other one has angled coils in a \/\/ configuration (side view). From the front you can vacuum the front \ of the coil. By moving away from the wall and taking the machine screws out and removing the back cover, you can vacuum the / of the coil. Well, part of it. That compressor makes access tricky.

However there is no way to get vacuum or brush anywhere near the inner /\ coils. I blow them off with a can of spray air, as best I can. It's better than nothing but doesn't really clean them.

Or put it on the back deck and take the water hose to it. That will
remove a lot of what air won't touch.

There is a way to clean them. I followed what this guy did on Youtube.
https://www.youtube.com/watch?v=Ms28ypfO2Jw

It does work. Just be very very sure that all three sides are completely
sealed or the dust will come flying out and go everywhere. I tried using
foam pipe insulators jammed in between the cabinets and the side of the
refrigerator. This did not stop all the dust from escaping out the sides.

They make a coil cleaner for outside condenser coils , then hosed off.
Wouldn't it work outside on the fridge, too...

The coils are a different design. I'd expect
the refrig coils don't really need such
chemical action.

Don't see why not. The crud I've seen on some condenser coils - and on
dehumidifiers - would never come off with an air hose and would
require a bit of work with a water hose

I just bought one with coils on the back. It is a small hotel sized one (not the mini dorm size, but just slightly under 18 cu ft.) I was very careful moving it, those coils run the full height of the fridge and look very fragile.

They might sell a special brush for this, long and thin.

i have fixed office machines for a lifetime. there was a nun in charge of a catholic school. they used super cheap paper in the copier. clean up was a mess. one day i moved the copier outside and blew the paper dust out with compressor.

it was a windy day, the dust blew away, but the nun was mad i had done this.. till i reminded her it saved her 75 bucks for a hours labor, with my vacuum and artists brush....

Me and my brother have 20lb CO2 tanks of the type used with soft drink dispensing machines. The liquid CO2 boiling into gas inside the tanks lasts a long time for uses like inflating tires, blowing dirt out HVAC equipment, checking pipes for leaks and blowing dirt out of computers plus other office equipment. A computer, even in the cleanest of offices, will fill up with dust elephants in no time. We'd take the computers from a business outside, to the loading dock if there was one, then blow the dirt out of them with CO2 at 100psi. The people there couldn't believe how muck dirt we got out of their machines. We couldn't turn off the big Cisco routers and switches to clean them so we used a combination of the CO2, tarp material cut to size for the purpose and a shop-vac. Any office equipment with a cooling fan would get full of dust. I like business computers because they usually have one latch to pull in order to remove a side cover which makes servicing them so much easier. Oh yea, me and my brother were tortured by nuns when we were little kids. We still have nightmares about giant penguins chasing us. ^_^

My desktop PC has a foam filter I made in the unused 3 - 5 1/4" drive
bays with a 5" fan behind it, with the fan speed adjusted so the
internal pressure inside the PC is is positive relative to room
pressure. All the cooling air comes through the filter, and everything
inside the PC case stays way cleaner than without the filter. I just
pull out the filter once in a while and vac it off.

The last time I had this problem, I had the gardener come in and blow it
out with his leaf blower. Seriously. I wheeled the fridge over to the
door so the stuff would blow outside.

think compressor. can make a dirt. put fridge or whatever outside so the dust blows away.

i have fixed office machines for a lifetime. there was a nun in charge of a catholic school. they used super cheap paper in the copier. clean up was a mess. one day i moved the copier outside and blew the paper dust out with compressor.

it was a windy day, the dust blew away, but the nun was mad i had done this.. till i reminded her it saved her 75 bucks for a hours labor, with my vacuum and artists brush....

she said ok but dont do it again......

Me and my brother have 20lb CO2 tanks of the type used with soft drink dispensing machines. The liquid CO2 boiling into gas inside the tanks lasts a long time for uses like inflating tires, blowing dirt out HVAC equipment, checking pipes for leaks and blowing dirt out of computers plus other office equipment. A computer, even in the cleanest of offices, will fill up with dust elephants in no time. We'd take the computers from a business outside, to the loading dock if there was one, then blow the dirt out of them with CO2 at 100psi. The people there couldn't believe how muck dirt we got out of their machines. We couldn't turn off the big Cisco routers and switches to clean them so we used a combination of the CO2, tarp material cut to size for the purpose and a shop-vac. Any office equipment with a cooling fan would get full of dust. I like business computers because they usually have one latch to pull in order to remove a side cover which makes servicing them so much easier. Oh yea, me and my brother were tortured by nuns when we were little kids. We still have nightmares about giant penguins chasing us.. ^_^

My desktop PC has a foam filter I made in the unused 3 - 5 1/4" drive
bays with a 5" fan behind it, with the fan speed adjusted so the
internal pressure inside the PC is is positive relative to room
pressure. All the cooling air comes through the filter, and everything
inside the PC case stays way cleaner than without the filter. I just
pull out the filter once in a while and vac it off.


That's something I've had in some of my towers that I built. I purchased the cases based on the fact that they had factory filters. A lot of rack mount server cases are also manufactured with built in filters. I've even cut squares of the foam filter material made for HVAC systems and stuck them on the front of my computer case vent with toothpicks or paperclips. Dirt is the enemy. My 42lb Dell Precision workstations have huge heatsinks inside that don't build up dirt that quickly because of the surface area but are really easy to clean with a vacuum cleaner, paint brush and some canned air. I have a lot of Dell desktop computers and they're so easy to service because I can pull one latch and the side cover comes off. In the good old days when I was building systems it took a bucket of screws to put one together. I'm lazy theses days and want something easy to work on. ^_^

She didn't have the kids clean the erasers by banging them against the
outside wall?

time you saw one of these beasts? ^_^

Hehehe. Those were in some of the grade schools i've had the... ehm,
pleasure of attending some years ago.

Hmmm. I most certainly don't understand how I can access a copy of a
zip file but then not be able to unzip it so I can watch it. That
seems VERY clever!

You nailed it! Under-side coils are impossible to get very clean. And, as
they clog-up with dust, the condenser temps go up, which means the compressor
pressures go way up, shortening the compressor life. The old-style rear
condenser units are WAY more reliable. I've seen them run 40+ years.
It might be true that the fan-cooled coils are more efficient, but that
efficiency will be gone within a month in most households where the coils will
quickly get covered with dust.
