The ozone lie needs to be removed. Chlorofluorocarbons do not do anything to the ozone layer. Chlorine and fluorine are negative ions and do not react with negative ozone (-2 charge). The lie was made by Dupont because the patent on their refrigerant was expiring so they devised and bribed for this lie to force the corrupt government to buy their new refrigerant. The ozone layer naturally expands and contracts like the arctic ice!!
I cosmetically restored a 1927 GE Monitor Top refrigerator. It has an actuation switch that involves a capacitor and a points system using an electronic resistor to "start" the compressor. Since the unit had not functioned since 1940, it took a bit of manipulation of the switch system to get the old fridge to start up. It did, and it freezes the upper compartment, and the residual cold air then sinks to the lower fresh food compartment. I made the mistake of cracking open (just a hair) the sulphur dioxide coolant valve to check coolant pressure. About a flea fart of the noxious gas escaped, hitting my olfactory sense as would a sledgehammer. Nasty stuff therein, indeed. But the machine still works almost a hundred years on!
I recently retired from the HVAC service industry, and enjoyed this video; well- researched and explained. A big takeaway that many people don't understand, and you did explain it, is that refrigerators, freezers and air conditioners do not generate cold! They simply transfer heat (heat pumps, anyone?)
In the 1970s I delivered a new refrigerator to a massive house that was built by an oil man during the Depression when he was one of the few with money. His daughter was moving into the house and it had never had a refrigerator in the kitchen; the house was built with a walk in refrigerator and walk in freezer like a restaurant! They were no longer operating so the new residents turned them into a pantry and a storage closet…
Wow, what a flash! My great grand father had an ice business in Connecticut, as his fathers before him had since the 1700's. We ended up inheriting one of the horse drawn cutters, an ice saw, fork and a set of massive tongs. My dad showed me the location of the old sawdust insulated ice-house and pictures in an old family photo album of the operations, much like the photo's you showed us here. Thanks for posting!
The first refrigerator I remember my folks having was when I was a child. I was born in 1945. It was a FRIGIDAIRE, probably about 12 or 14 cubic ft. It had a GOLD CROWN on the front door, and inside at the top was a small freezer that could fit about 2 ice trays and 4 or 6 small boxes of frozen vegetables. That thing ran for decades ! In 1960, they bought a new Kenmore COLDSPOT, about 22 cubic ft. At the time, it was the most advanced Sears sold. Bottom door freezer(frost free with huge manual ice bucket. The top door refrigerator had a lazy susan vegetable tray and a vertical shelf on the left that pulled out for milk and juice storage. It was wonderful. All shelves were stainless and glass, no plastic.I wish they still made that version. More intelligently planned than a new modern one with a video screen and music !
Funny story.My great grandmothers 1940's GE fridge still working after all these years,is on our back porch, and is the beer fridge,etc. When our new kitchen fridge had a problem under warranty the young repair man came. He saw the old fridge ,and i pointed out that it.'s still works after 70 years..He said quote:'wow that's an antique, what's it from the 70's or 80's?'
Yeah I remember something I had to get service in the house and a young kid was one of the techs. He was looking at the TV from 1984 as if he had never seen one and he was trying to figure out how old it was. 😂
After a successful career, John Gorrie died impoverished, alone, and humiliated. How sad for anyone, but especially for a talented, caring man with courage and vision. History hails those who succeed. We rarely hear about the many more who, despite heroic efforts, fail to realize their dream, yet, if it wasn't for their efforts, progress would cease.
Nikola Tesla gave us A/C electricity Thomas Edison ripped Tesla off and gave us basically nothing in comparison. You wanna talk about injustice? Or how about Alan Turing WHAT did he do? Gave us the digital computer, that's all. He committed suicide after being humiliated because he was gay... while one of the smartest people that ever lived Tesla died broke in a hotel in NYC.
The first artificial refrigeration system was developed in the mid-18th century. In 1755, a Scottish professor named William Cullen demonstrated a small-scale refrigeration system, utilizing a pump to create a vacuum that evaporated ether. This process absorbed heat, cooling the surrounding area. Although this was more of a scientific experiment than a practical invention, it marked the beginning of refrigeration technology.
In the mid 1940s we had a 40 foot deep cistern with a cold spring running through the bottom. A chain was used to lower a basket containing food that we wanted to keep cold down into the cold water pool. In the house stood an ice box into which two cubic-foot blocks of ice were inserted into the insulated top portion. The melting ice blocks would cool the air around them, which would then descend through openings into the insulated food storage area below. New blocks of ice would have to be purchased every few days. Did I mention that this old house had no electricity to run a refrigerator?
No, new refrigerators don't last only 3-4 years, Where did you get that from? Mine is approaching 20 years and still doing fine. Same with my sister's. Refrigerators are among the few home appliances that don't tend to pack up after a few years. And what do you mean, cost a fortune to repair? Who spends money these days on repairing home appliances? What workshop is even in the business of repairing such stuff? TV and radio repair once used to be a viable business, but these days people buy a new set before they even break down.
Watching this video reminded me of how most of the old folks I knew as a boy in the 1970s and 80s still referred to refrigerators in general as Frigidaires and iceboxes
Boomer here! Born in 1945. Had icebox until age 12. Hey! The ice man is coming! By the way, I worked at a missile test range in the Marshall Islands in the 1990s. The world for refrigerator in Marshalles language is "icebox." I wonder where that came from?
Hello Sam Denby, very interesting video! With all due respect, the correct terminology for Freon 12 is, Refrigerant-12, or R-12. Refrigerant-12 is a dry liquid chemical called Chlorofluorocarbon (CFC) that is a refrigerant that contains chlorine, fluorine, and carbon atoms. I wish to tell you that R-12 has a boiling point of 12 degrees above Fahrenheit and was used in the air conditioning systems in cars, trucks and busses. By the way, R-22 has a boiling point of 22 degrease above Fahrenheit and was used in office buildings, hospitals, factories, homes, window units and refrigerators. In plain in English, refrigerant-12 and refrigerant-22 are NOT brand names, but in the mean time, Freon-12, and Freon-22 are trademarks of DuPont chemical company. I must say that your videos are outstanding. Please reply. Dave...
I still remember those metal icetrays with the handles you pull up to release the ice. Sometimes it hurt. (I still own some.) Sure appreciate having an icemaker! Iced tea for me all year long.
We still have a refrigerator that runs on natural gas, first made in the 1920s. It's in the garage, and still runs and is big enough to hold soft drinks and the over flow from the kitchen. We just got rid of our 23 year old Sears Kenmore fridge and replaced it with a Samsung unit that my partner liked. I didn't like it and pointed out at the store that you could not remove the drawers all the way. Any way, the ice maker has been replaced twice in two years, the thermostat once and the door seal once. AND of course my partner now complains about not being able to remove the drawers so she can clean them!

I remember a time when gas refrigerators were very popular. They were totally silent in operation and, with no moving parts, never wore out. Electric absorption type refrigerators were also available, but were more expensive to operate than the compressor type.
I grew up with a little Norge refrigerator with a belt driven compressor. I well remember the day it failed and leaked sulfur dioxide. We stayed outside all day until it was serviced. By then they had grown and it was difficult to find one small enough for our kitchen.
The cooling systems of refrigerators can last easily 50 years or longer because the moving parts, basically an electrically powered pump, is not driven particularly hard. The reason refrigerators wear out is because the insulation depreciates over time. The temperature difference between outside and inside causes this material to slowly collect condensation, become soaked full of water and lose its insulating properties. This is why refrigerators lose efficiency as they age and use more electricity. Manufacturers know of this effect and there are ways of solving it, but I guess that they want people to buy a new refrigerator every 10 years.
A cat named Carrier developed the ac system to cool type-setting in newspaper production.. Wild swings in temps would warp the printing presses and cause major problems..............he was never given credit.
Evansville Indiana was the refrigerator capital of the United States, producing 3,800 per day. The college “Refrigerator Bowl” was held at the Evansville Reitz High School Football Stadium aka “Reitz Bowl” from 1948-1956
R12, because it was inert and inexpensive, was used as the propellant in aerosol cans. Deoderant was one of the most popular spray cans at the time, so every time someone sprayed their underarms R12 was released to the atmosphere. The Kyoto Accords outlawed the use of R12, based on the scientific assertion that R12 would rise to the upper atmosphere and dissassociate O3 (ozone), which is created naturally by sunlight. This assertion was backed up by an observed "hole" in the Ozone layer over Antartica. It has been 40+ years now and the "hole" over Antartica has not gotten smaller. Why is that? Was it the abscence of sunlight, due to the perpetual darkness of the Antartic winters, that created the Ozone hole or R12? Various new refridgerants have come and gone since and the "new" reason for their demise is GWP (Global Warming Potential). These new refridgerants require higher operating pressures which is why compressors are short lived. Others are flammable (e.g. R600 which is Isobutane) and there have been cases where refridgerators have exploded in kitchens when leaks occured near a source of ignition. Between the EPA and other government mandates we may all be back to using Ice Boxes soon.
What about the Australian fridge (Coolgardie?) basically a tray of water wicks away by Hessian hanging over all sides of a mesh structure, the airflow through the wet Hessian cools the food inside, used no electricity so perfect for in the bush
So it was that the world’s first artificial refrigeration was performed by Cullen in Glasgow in 1748 with the world’s first demonstration of practical refrigeration eight years later. He used a pump to create a vacuum in a container of diethyl ether and when the diethyl ether began to boil, it absorbed the heat from its surroundings and began to cool. Some accounts say ice could be seen.
I'm not an authority, but years ago I read a book about how mechanical refrigeration began in the late 19th century with meat packing houses who were desperate to get it. These early systems used ammonia and sulfur dioxide and barely worked at all. It wasn't until around WW2 that modern refrigeration, the way we know it today, came of age
There was a woman woman on TH-cam a few years back a local news affiliate did a story on. Her 1927-29 refrigerator was being replaced and the old refrigerator was still in use and never serviced. Unfortunately the old fridge ended up in a recycling program and who knows what happened to it.
All these 'claims' to the invention of Refrigeration Systems ?? I have worked 51 years in HVAC in Australia. Here in tye state of Victoria, our Industry Body recognises HARRISON from Geelong, Victoria 1854 as the Founder and Invention of the Refrigeration Principle. It was later adopted by the Carrier Corporation and General Electric USA. It is mentioned correctly as I was taught it.
Not quite true. No one inventor can claim credit. American Jacob Perkins built the first working refrigeration system in 1834. Several other inventors then had some success. Australian James Harrison built the first commercial refrigeration plant in 1854.
Two things should be clarified here. Something you didn't include in your "basic intro to kinetic theory of gasses", is that compressing a gas makes it heat up, and allowing it to expand makes it cool down, a critical factor in how refrigerators and air conditioners work (yes, you explained that higher temperature would mean higher pressure, but this is sort of the converse of that, and is worth looking at in more detail). If you think about a gas contained in a cylinder with a piston pushing in to reduce the volume (as in an internal combustion during the compression stroke), any gas molecules hitting that part of the cylinder, ie, the piston face, will bounce back faster than they hit, because the piston is moving towards them. So the average speed of the molecules increases, which is what we perceive as higher temperature. That's why high-compression diesel engines don't need spark plugs. Also the "expander valve" is really just a nozzle with a small opening, or even just a point where the tube suddenly narrows for a length. That's how the pressure difference between the two parts of the system is maintained.
Now after we watched this doco needs to go and grab their favourite alcohol and naturally walk to the fridge and drop a couple of ice cubes. Ahhhhhhh that really feels smooth and fresh 🤪
Why must we always start at the beginning of the history? Why not start at the beginning of the development of the technology that allowed for the refrigerator to become a common appliance?
Permanently magnet instant freezing can be used in incubator condense matter into agriculture instant crop or expand air chamber flast air flow cool instantly befor freezing chamber
Hey man, this video was amazing I was looking for this topic for my video but I couldn't find anything You have a great card and if you continue on this path, you will succeed And don't worry about me, my channel is in Farsi
SO, The point you are trying to make is that no 1 single person created the refrigerator. It works that way with everything. It rubs me raw when I see young dudes making fun of how dumb old guys were in those old days. Those old guys laid the foundation to what we have today. todays young engineers would not have been able to create bluetooth or Wifi or the cellphone or AI without the work done by their predecessors. There was a tv show which laid all this out called CONNECTIONS. It is on TH-cam. Check it, it is FACINATING. !
Tullamore Dew Whiskey Irish , Ice and water ... As a matter of interest there is an Indian company that manufacture a " Clay Refrigerator " .... made from clay and uses water as a coolant . th-cam.com/video/WPYzV64dUuU/w-d-xo.html
I have read lot of educational books, seen lot of educational videos and everybody I know said " you are so smart " I keep on saing no I am not I just have different interests and that doesn't make me smart? I think we all are intelligent equally the only difference is what you are interested in? Knowlege is only how much education you have absorbed in your life so get to know as much as you can it will only increase your thinking as you will have more to think about?
I am with you . Carl Linde name should have been mentioned , without his ideas of refrigeration cycle nothing was possible.Carl Linde was Back bone of refrigeration.
The new kid on the refrigeration block is DC compressors. They are tiny refrigerant compressors controlled by circuitry to be more flexible and hardy. Run your 12 volt chest freezer in ECO mode, to prolong it's life. Take it in the car. Use it in a solar panel DC cabin. Run it in the back yard during picnics.Send the kids to college with one. It will be saved after graduation. It sips electric.
The so called DC compressors have an tiny inverter which provides 3phase AC to the compressors. There is no real DC motor with brushes inside a hermetic compressor on the whole world. The alternative are those shity Peltier element fridges which get powered by DC direct.
Excellent video. But please stop with the fake incidental added sounds like fake camera shutter sounds every time a photo is introduced. It’s unnatural, annoying, and make your very cool videos just noisy.
Let me help: Did you ask yourself, as you were writing this, WHY you included an environmental impact statement when discussing 19th century ice transport? I will tell you why. You went to college. You got your base level education from weak men whose only chance to message the world was to teach YOU that there political ideas belong in EVERYTHING you do. Don't worry. I come to you from GenX. Our college professors were burned out hippies left behind by the 60s. They tried to do the same to us. Unlearn it, if you want your work to be taken seriously. When an idea fits the story you are telling and advances the idea you are proposing, leave it in. But when it doesn't... FOCUS on what you are presenting, and leave out the misplaced nonsense. Everything does not fit everywhere. Your college professors' teaching that the need to sell windmills belongs in every work you create is nonsensical. From the moment you explained how loading ice onto sailing ships using wind propulsion gave Al Gore a woodie, I took everything else you said less seriously. As a general rule, that one line you think is the most clever is almost ALWAYS the line you should edit out before turning in your final submission. We learned to take our professors' Easter eggs about Richard Nixon out of our work, as adults. Your generation needs to learn the same thing. Understand that the academics who implanted this kind of thing in you, while you were getting your base education, are feckless people. They wish to communicate to the world through you, because that world never took THEM seriously. Stop letting them use you for this purpose.
@Kennedymcgovern - I figured too that he went to college exposed to Al Gore's ideology after hearing the familiar rhetoric. Very had to pass our knowledge to the new generation unless they unlearn a few things. I think most of us would rather avoid an argument. To the author of this video - you did a fantastic presentation but you are headed to even greater things if you pay attention to the comment.
I am sure that those fridges with the so described compressor on the top where ammonia adsorber ones which where powered by an electric heating element.
Gotta work on your English, " How were the first Refrigerators?" is an incomplete-illogical "sentence." ...maybe if you added the word, "Made" at the end it would have been better????
I’m no longer in the refrigeration industry however it’s at a very interesting point at the moment because of the phase out of HFC and HCFC refrigerants, currently people are trying to replace them with HFO’s which have no apparent affects to the environment however a number of them are toxic or flammable putting us back in the same situation we were in during the 1930’s

These new refridgerants require higher operating pressures which is why compressors are short lived. Others are flammable (e.g. R600 which is Isobutane) and there have been cases where refridgerators have exploded in kitchens when leaks occured near a source of ignition. Between the EPA and other government mandates we may all be back to using Ice Boxes soon.
Good Stuff. The Honeymooners had one. Amazing story how this happened. Got to keep my food fresh and my beer.🍺 cold. Thanks
2400 year old refrigeration system still in use in Persia. Also oldest sorbet.
Interesting ❤
What about the Australian fridge (Coolgardie?) basically a tray of water wicks away by Hessian hanging over all sides of a mesh structure, the airflow through the wet Hessian cools the food inside, used no electricity so perfect for in the bush
We call that a "swamp cooler", though it actually works better in dry climates than humid ones.
So it was that the world’s first artificial refrigeration was performed by Cullen in Glasgow in 1748 with the world’s first demonstration of practical refrigeration eight years later. He used a pump to create a vacuum in a container of diethyl ether and when the diethyl ether began to boil, it absorbed the heat from its surroundings and began to cool. Some accounts say ice could be seen.
I remember having an icebox camping with my parents when I was a kid in the 60’s, ice truck would come around daily. Brisbane, Australia
I'm not an authority, but years ago I read a book about how mechanical refrigeration began in the late 19th century with meat packing houses who were desperate to get it. These early systems used ammonia and sulfur dioxide and barely worked at all. It wasn't until around WW2 that modern refrigeration, the way we know it today, came of age
There was a woman woman on TH-cam a few years back a local news affiliate did a story on. Her 1927-29 refrigerator was being replaced and the old refrigerator was still in use and never serviced. Unfortunately the old fridge ended up in a recycling program and who knows what happened to it.
All these 'claims' to the invention of Refrigeration Systems ??
I have worked 51 years in HVAC in Australia. Here in tye state of Victoria, our Industry Body recognises HARRISON from Geelong, Victoria 1854 as the Founder and Invention of the Refrigeration Principle. It was later adopted by the Carrier Corporation and General Electric USA. It is mentioned correctly as I was taught it.
Not quite true. No one inventor can claim credit. American Jacob Perkins built the first working refrigeration system in 1834. Several other inventors then had some success. Australian James Harrison built the first commercial refrigeration plant in 1854.
Two things should be clarified here. Something you didn't include in your "basic intro to kinetic theory of gasses", is that compressing a gas makes it heat up, and allowing it to expand makes it cool down, a critical factor in how refrigerators and air conditioners work (yes, you explained that higher temperature would mean higher pressure, but this is sort of the converse of that, and is worth looking at in more detail). If you think about a gas contained in a cylinder with a piston pushing in to reduce the volume (as in an internal combustion during the compression stroke), any gas molecules hitting that part of the cylinder, ie, the piston face, will bounce back faster than they hit, because the piston is moving towards them. So the average speed of the molecules increases, which is what we perceive as higher temperature. That's why high-compression diesel engines don't need spark plugs.
Also the "expander valve" is really just a nozzle with a small opening, or even just a point where the tube suddenly narrows for a length. That's how the pressure difference between the two parts of the system is maintained.
My Mom called fridges ice boxes.
Refrigerators? How cool is that? 😂
Australia had, before asian manufacturing and modern containerisation, a long history of manufacturing self-sufficiency and industrial innovation.
Kind of ironic that the world complained about greenhouse gasses escaping through the hole in the ozone layer.
We'll all be using ice again when the oil runs out.
watching this 19th century ice transporting business reminded me of that scene from A Million Ways to Die in the West 😬 😂
North pole plenty ice
Not according to the enviromentalists😂
Well, nice explanation but the research doesn't point to Carl Linde in Germany. It's always the same when I look at videos made by people from the US.
Now after we watched this doco needs to go and grab their favourite alcohol and naturally walk to the fridge and drop a couple of ice cubes. Ahhhhhhh that really feels smooth and fresh 🤪
Australia shipped frozen meat to England by refrigerated shipping from 1888.❤😊
👍🙂
How were the first refrigerators what?
Boston baby I’m from there
💋
Why must we always start at the beginning of the history? Why not start at the beginning of the development of the technology that allowed for the refrigerator to become a common appliance?
American invention 🇺🇸
Crossley was left out.
Permanently magnet instant freezing can be used in incubator condense matter into agriculture instant crop or expand air chamber flast air flow cool instantly befor freezing chamber
Could have been a good video but again another editor that likes music behind somebody talking
the first one ,was in the of ice age ,,
BRRRRRRRRRRRRR!
Hey man, this video was amazing
I was looking for this topic for my video but I couldn't find anything
You have a great card and if you continue on this path, you will succeed
And don't worry about me, my channel is in Farsi
I don't know. How WERE the first refrigerators?
SO, The point you are trying to make is that no 1 single person created the refrigerator. It works that way with everything. It rubs me
raw when I see young dudes making fun of how dumb old guys were in those old days. Those old guys laid the foundation to what
we have today. todays young engineers would not have been able to create bluetooth or Wifi or the cellphone or AI without the work
done by their predecessors. There was a tv show which laid all this out called CONNECTIONS. It is on TH-cam. Check it, it is
FACINATING.
!
Tullamore Dew Whiskey Irish , Ice and water ... As a matter of interest there is an Indian company that manufacture a " Clay Refrigerator " .... made from clay and uses water as a coolant .

What about FREDRICK MCKINLEY JONES????!
Thermo King??!!!
I have read lot of educational books, seen lot of educational videos and everybody I know said " you are so smart " I keep on saing no I am not I just have different interests and that doesn't make me smart? I think we all are intelligent equally the only difference is what you are interested in? Knowlege is only how much education you have absorbed in your life so get to know as much as you can it will only increase your thinking as you will have more to think about?
Ski juice on the rocks.
No Mention of Carl Linde!?!? You're offending us Germans!
I am with you . Carl Linde name should have been mentioned , without his ideas of refrigeration cycle nothing was possible.Carl Linde was Back bone of refrigeration.
There was no iceman only three stooges
The new kid on the refrigeration block is DC compressors. They are tiny refrigerant compressors controlled by circuitry to be more flexible and hardy. Run your 12 volt chest freezer in ECO mode, to prolong it's life. Take it in the car. Use it in a solar panel DC cabin. Run it in the back yard during picnics.Send the kids to college with one. It will be saved after graduation. It sips electric.
And it doesn’t get cold worth a shit and they have high failure rates
The so called DC compressors have an tiny inverter which provides 3phase AC to the compressors. There is no real DC motor with brushes inside a hermetic compressor on the whole world. The alternative are those shity Peltier element fridges which get powered by DC direct.
@matneu27 ....but DC compressors are controlled and rugged with tricks like ECO mode, which I always use.
Excellent video. But please stop with the fake incidental added sounds like fake camera shutter sounds every time a photo is introduced. It’s unnatural, annoying, and make your very cool videos just noisy.
💯 agree 👍
Let me help:
Did you ask yourself, as you were writing this, WHY you included an environmental impact statement when discussing 19th century ice transport?
I will tell you why. You went to college. You got your base level education from weak men whose only chance to message the world was to teach YOU that there political ideas belong in EVERYTHING you do.
Don't worry. I come to you from GenX. Our college professors were burned out hippies left behind by the 60s. They tried to do the same to us.
Unlearn it, if you want your work to be taken seriously. When an idea fits the story you are telling and advances the idea you are proposing, leave it in. But when it doesn't... FOCUS on what you are presenting, and leave out the misplaced nonsense.
Everything does not fit everywhere. Your college professors' teaching that the need to sell windmills belongs in every work you create is nonsensical.
From the moment you explained how loading ice onto sailing ships using wind propulsion gave Al Gore a woodie, I took everything else you said less seriously.
As a general rule, that one line you think is the most clever is almost ALWAYS the line you should edit out before turning in your final submission.
We learned to take our professors' Easter eggs about Richard Nixon out of our work, as adults. Your generation needs to learn the same thing.
Understand that the academics who implanted this kind of thing in you, while you were getting your base education, are feckless people. They wish to communicate to the world through you, because that world never took THEM seriously. Stop letting them use you for this purpose.
@Kennedymcgovern - I figured too that he went to college exposed to Al Gore's ideology after hearing the familiar rhetoric. Very had to pass our knowledge to the new generation unless they unlearn a few things. I think most of us would rather avoid an argument. To the author of this video - you did a fantastic presentation but you are headed to even greater things if you pay attention to the comment.
Annoying clicking noises in audio
Not even a mention of absorption refrigerators. Shame.
I am sure that those fridges with the so described compressor on the top where ammonia adsorber ones which where powered by an electric heating element.
New technologies always threaten jobs.
Gotta work on your English, " How were the first Refrigerators?" is an incomplete-illogical "sentence." ...maybe if you added the word, "Made" at the end it would have been better????
I can't focus with the constant G*d D*amned clicking!!!
The title for this might get the gold for the worst butchered grammar ever in a YT title. Makes less than no sense.
A Black man named Fred Jones brought refrigeration to the masses, do more research bruh
I’m no longer in the refrigeration industry however it’s at a very interesting point at the moment because of the phase out of HFC and HCFC refrigerants, currently people are trying to replace them with HFO’s which have no apparent affects to the environment however a number of them are toxic or flammable putting us back in the same situation we were in during the 1930’s
and i thought sears invented the first refrigerator 🤣😂🤣🤣😅😂😂
Very interesting video.
Our kayaking group often visits Lake Potanipo in NH, which was the largest icehouse in the world at the time.
