refrigerated air

If you are thinking : ‘What a simple question, I know the answer to that! It is used to control the temperature on my refrigerator’

You are absolutely right ! In fact most people I have asked this question seem to know thus far. But how does turning a knob control the temperature ?


The refrigeration cycle

The fridge works in a rather simple way:

Refrigerant (liq) takes up heat from the object you want to cool

Changes state from liquid to gas

Compressor pressurizes fluid, heating it up. ( Why ? for better heat exchange )

This hot gas meets the cool gas outside, changing state back to liquid

Further de-pressurizes as it heads back

Repeat


The thermostat switch

If the temperature inside the fridge goes up, the compressor must be turned on to circulate the refrigerant.

Here’s the crux of the post :

That knob determines when the compressor is to be turned on !

That knob is coupled to a screw type mechanism which lowers or moves up as it is rotated.

A bellow ( like a balloon ) keeps expanding as the temperature inside the fridge increases until it hits the arm and flicks the thermostat;

Compressor : ON ;

Refrigeration cycle : START

That’s the story of that mysterious knob that had baffled me for quite some time.

Have a great day!

Boiled creme treat

Boiled creme treats can be found in almost every kitchen and household in Skyrim, and once you get a taste you’ll know why! While there is quite a lot of preparation involved in making these delicious pastries, it will be well worth the effort (and this recipe serves 10, so prepare to wow your dinner guests)!

You will need:
Pastry
1 cup butter, softened
1 egg
4 cups flour
2 tsp dry yeast
1 ½ cups milk, lukewarm
½ cup caster sugar
1 tsp salt
2 tsp vanilla essence

Filling
1 cup heavy cream
2 vanilla beans, scraped
1 tsp vanilla essence
3 egg yolks
1/3 cup caster sugar

Glaze
¼ cup butter, melted
½ cup icing sugar
1 tsp vanilla essence

Method:
Combine the dry pastry ingredients in a mixing bowl. Slowly add the milk and stir. Add the butter and egg, and knead by hand until the dough is smooth.

Place the dough in a warm space and cover with a cloth for an hour or until dough has doubled in size. Knead the dough to push out the air, then refrigerate.

On low heat, combine the cream, vanilla beans, and vanilla essence. In another bowl, whip the egg yolks and sugar until smooth, and pour into the creme mixture slowly, stirring the whole time. Continue whisking on low heat until the entire creme mixture is smooth and even.

To make the glaze, beat together the butter, sugar, and vanilla essence until smooth. Leave in a warm place until ready to use.

Preheat your oven to 200C/400F. Grease a large baking tray and set aside.

Roll your dough out into a flat rectangle about ½" thick. Use a small bowl (3-4") or similar round mould to cut circular shapes from the dough, then lay them evenly on your baking tray. Using a spoon, make a deep indentation in the centre of each dough round (do not cut all the way to the bottom), then bake for 10 mins. Remove from the oven and fill each well with creme, then glaze with a basting brush. Bake for another 10-15 mins, or until golden brown.

Wait until completely cool to eat.

The gentle rays of the mid-afternoon sun pierced through the windowpanes. You laid, sprawled over the couch, reading a magazine in the hopes to cure your case of boredom. Well, it was safe to say that it wasn’t working. 

You groaned into the pages, tossed the magazine onto the coffee table and grabbed your phone instead. You resisted the urge of calling your boyfriend because you knew he was probably busy at the studio or something of the sorts. Again, you groaned as your phone also did not cure your boredom and instead resorted to doing one of your favorite things: eating. That was an obvious activity you and Jin had shared. Everyone had to eat to survive, but for you and Jin eating was also a nice leisure activity. You two promised that one day, you guys would travel the world and try every single type food this planet had to offer.

The refrigerator blasted cool air, sending shivers down your spine. Scanning for something to eat, you were sadly met with nothing but an opened pack of chilled beer. You cursed at yourself for forgetting to go grocery shopping again. At least now, you found yourself something to keep you occupied. 

You quickly slipped on something more decent than your pyjamas and gathered your purse and other belongings. Humming to your boyfriend’s latest song, you practically skipped to the front door thinking about what to make for dinner. You always loved to cook for Jin. He would always say how your homemade meals were his favorite, even though you knew you weren’t that good of a cook. 

You swing the door open, getting ready to leave, but you were met with something, or someone, quite unexpected. A woman sporting red lipstick haphazardly drawn upon her lips wearing an outfit that revealed more than you would’ve liked to see was standing in front of your door.

Trading Favors

@noodlecupcakes

The nice thing about having knowledge instead of just supplies during the apocalypse was that for the most part, people had to play nice with you in order for you to do anything for them.  Anyone with a sufficiently big enough caliber of gun could take your supplies but when you knew how to build generators, how to create water purifiers, how to rewire houses for long forgotten luxuries like refrigerators and stoves and air conditioning, they couldn’t just force that out of you.  That they had to negotiate for.  And when the pick up truck rolled up to the porch of the house he’d turned into his little home base and a few guys armed to the teeth got out, he figured that was what they were there for.

A Masters in Mechanical Engineering from MIT took you places back before the world disappeared into the bellies of zombies, but now when everything around them was falling apart, it went even further.  He knew how he looked, young and a little underfed, black hair shaggy and long all the way down to his shoulderblades by this point.  He didn’t look like the sort of person who’d survive in a world like this, which was probably at least part of why he had.  He watched the little group head up towards him where he stood on the porch, rifle resting on his shoulders, wariness looking out of place on a vaguely Asian, slightly too pretty face.  He didn’t speak first, waiting for them to say something that would allow him to take measure of them.  They weren’t the first survivors that had come to his door asking for his technical expertise and mechanical know-how.  And unless a miracle happened and the world fixed itself overnight, they surely wouldn’t be the last.

LEBANON. Tyre. July 2006. Marco di Lauro’s coverage of the 2006 Lebanon War. Here, aftermaths of Israeli airstrikes. All pictures: Marco Di Lauro/Getty Images [Part 1]

Photograph 1: Two Lebanese civilians wait for further treatment upon arrival at the hospital. According to Hospital Officials, a family traveling in a van trying to flee the villages south of Tyre was hit by an Israeli warplane reportedly killing 13 people as well as injuring 13. July 23, 2006.

Photograph 2: 3-year-old, Nimar Ramait recovers in his hospital bed after he was injured by a bomb dropped by an Israeli war plane on a water canal where he was swimming. For a sixth day, Israel continued it’s extensive bombing of villages and the civilian population in Southern Lebanon. July 17, 2006.

Photograph 3: The bodies of the victims of the Qana Israeli air strike wrapped in plastic having been brought from Qana to the morgue. Twenty-two bodies were brought to the morgue wrapped in plastic and loaded into a refrigerator truck. The Israeli air strike killed 56 civilians of which 34 of them were children, in the worst attack since the fighting began 19 days ago. July 30, 2006.

Photograph 4: 18 year old Zahra Al-Jamira cries in shock after she realized that her face is burnt as a result of a bomb dropped by an Israeli warplane. For a seventh day, Israel continued its extensive bombing of villages and the civilian population in Southern Lebanon. July 18, 2006.

The 2006 Lebanon War, also called the 2006 Israel–Hezbollah War was a 34-day military conflict in Lebanon, Northern Israel and the Golan Heights. The principal parties were Hezbollah paramilitary forces and the Israel Defence Forces (IDF). The conflict is believed to have killed between 1,191 and 1,300 Lebanese people (mostly civilians), and 165 Israelis (including 44 civilians). It severely damaged Lebanese civil infrastructure, and displaced approximately one million Lebanese and 300,000–500,000 Israelis.

Various groups and individuals accused both Israel and Hezbollah of violations of these laws during the conflict, and warned of possible war crimes. These allegations included intentional attacks on civilian populations or infrastructure, disproportionate or indiscriminate attacks, the use of human shields, and the use of prohibited weapons. 

No formal charges have been filed against either group.

‘Til Our Eyes Meet: Photograph (Final Part)

Loving can hurt, loving can hurt sometimes…
They’d only just found each other, only to be torn apart.
We keep this love in a photograph…
Will their love be able to survive the torments of war?
Holding me closer ‘til our eyes meet…
Together and apart
Loving can heal, loving can mend your soul
And it’s the only thing we take with us when we die…
Always waiting, always wanting.
Hearing you whisper through the phone,
“Wait for me to come home.”

More Than You Ever Wanted to Know About Mechanical Engineering: Refrigerators

We’ve spent some time on the second law of thermodynamics - energy flows naturally from high potential to low, from hot to cold. Most of us have refrigerators or air conditioners in our dwellings - devices which seem to violate this law. They somehow move heat out of a colder space and into a hotter space. So what is going on here?

The short answer is that the refrigerant in these devices acts as a temporary energy storage medium - by some clever manipulation, we can move the refrigerant through a cycle such that at the point it travels through the space we want to cool it absorbs energy, which it needs to dump when it gets to the warmer exhaust space.

Here’s a typical refrigerator schematic.

Refrigerant enters the compressor as vapor. The compressor does work to increase its pressure. Increasing its pressure also increases its temperature, so by the time it hits the condenser it’s relatively hot. In fact, it’s hot enough relative to the surrounding environment that it sheds heat as it flows through the condenser. By the time it leaves, it’s condensed and much cooler, although it’s still at a very high pressure. It goes through an expansion valve from here, which drastically drops both its temperature and pressure. So it enters the evaporator as a low temperature, low pressure liquid. In this state, it is low enough energy that it absorbs energy from the surrounding environment going through the evaporator. When it leaves, it’s a vapor again, ready reenter the compressor and start another cycle.

This works because we are injecting energy into the cycle in the form of work done by the compressor in order to get the refrigerant to a state where the heat it absorbed from the refrigerated space can be dumped to the outside environment.

Why Suspicion of Luxury Brands is Essential.

I’m reproducing my breakdown from this post into its own post, since I really feel this information should be spread and is important even outside of the original context.

People often assume expensive things are better than cheap ones (sometimes they are, sometimes they aren’t, and oftentimes the extra quality isn’t proportional to the extra expense) and people also fall prey to conspicuous consumption, also known as “keeping up with the Joneses,” where you buy something not because you want or need it, but because you’re trying to show off.

This is the business model used by TONS of companies, up-price a generally okay product and let the cost convince people it is the better buy.

Häagen-Dazs ice cream was originally sold cheaply under a different name, in an attempt to provide a better product more cheaply than competitors, but consumers assumed it wasn’t good because of the price, and a fancy name and price hike later it took the country by storm.

Monster and Pear cables sell cables that perform no better than store brand but a combination of marketing and cost make them desirable to people with too much money and too little understanding of the tech.

Beats Headphones are vastly overpriced for their performance (and aren’t particularly durable either), but they’re pricey, so they’re a status symbol, and they put weights where they’d normally have hollow plastic so they’ll be heavier (people associate heavy things with quality construction.)

Double blind tests confirm time after time that wine, bottled water, and food in general is perceived as tasting better when people are told they are drinking the pricey stuff instead of the cheap stuff. Pabst Blue Ribbon, one of the shittiest malt liquors this side of Schlitz, has positioned itself as a luxury brand in China, selling the exact same swill hipsters buy and drink ironically at Jack Daniel’s Black Label prices.

This is also literally why lobster is considered a rich-person food. It used to be a garbage fish, the hard to open, bland-flavored giant mud-bugs you’d sweep up in nets while fishing for things that people actually wanted to eat. They served it in prisons because it was cheap. The opening up of the American west to rail travel and the explosion of newly-wealthy Westerners isolated from the New England old money allowed sellers to ship the things in by rail and alter car, sell them at a huge markup after drowning them in butter, and convinced a whole generation of newly wealthy that it was a delicacy. Then the newly rich spread it back East, and now you

And if you know anyone who can afford, say, a Jenn-Air refrigerator (they go so far as to have no-advertised-price policies, IE, “if you have to ask you can’t afford it.) how reliable it’s been, then compare to the one that you rent as part of your apartment.

People need to know about these impulses and recognize that they have them, because recognizing an impulse is there is essential to resisting it. Making an informed decision that best benefits you as a consumer rather than the corporations you’re buying from is in your best interest.

Ironically, there’s an opposite issue where one assumes that, for instance, a dollar store is going to provide you with your best value to cost, whereas if you can afford to get the larger $5 size of a foodstuff, say, frozen fish, you’ll be getting more than five times what you get in the $1 package, because bulk if often cheaper. A two-liter of soda routinely costs the same or less as the 16 oz bottle, for instance. and the per-unit price is more important for gauging how to stretch your dollar in normal grocery stores and big box stores than the package price (presuming you have the luxury of being able to afford the larger size and being able to use it all before it goes bad.)

Hope this helps some folks.

Welcome to #ATCinIndia

“There is probably no country with a bigger challenge–looking at the number of people, the level of economic growth, the number of people who don’t have access to electricity–probably nobody has a bigger challenge than India.”

That’s what America’s top climate negotiator, Todd Stern, told me during our final interview the other day. Stern was stepping down after 7 years in the Obama Administration, where he negotiated with nearly 200 countries on cutting carbon emissions. More than any of those other countries, he told me, India is now being asked to climb a very steep hill.

I met Stern in the run-up to COP 21, the summit in Paris last December that produced the most ambitious climate deal ever. The agreement aims to limit carbon emissions and prevent global temperatures from rising more than 2 degrees Celsius. Four months after that summit, I wanted to explore what it will take to make an agreement like this work. So All Things Considered producer Matt Ozug, NPR photographer David Gilkey, and I booked our plane tickets to India.

The UN estimates that 400 million Indian people don’t have reliable access to electricity. That’s far greater than the entire population of the United States. India is already the third-highest carbon emitter in the world, behind China and the U.S. But its per capita emissions are relatively low. As India’s chief negotiator in Paris, Ajay Mathur, recently told me, “We need to increase the energy supply by 4 to 5 times what it is now” in order to give people a decent quality of life. The question is whether India can provide its people with air conditioners, refrigerators, cars, and other amenities that Americans take for granted…without emitting massive amounts of carbon in the process. It is a path that no highly-developed country has walked before.

At the same time, people in India are uniquely susceptible to the impacts of climate change. Maplecroft Risk Assessment recently analyzed “populations most exposed to natural hazards,” like cyclones, droughts, and erratic monsoons. India came in #1. Richard Hewston of Maplecroft told me the people most affected by the impacts of climate change tend to be “the poorest people of the city, living in areas that are most exposed. These kinds of populations don’t have resources to prepare for or recover from natural hazards.”

Our reporting trip begins in New Delhi, India’s capital. Temperatures have been creeping close to 110 degrees every day this week. The air quality is the worst of any city in the world, according to the World Health organization. In Delhi, we’ll explore what is being done now to address climate change, and whether public pressure might shape national policy.

From Delhi, we travel to India’s Eastern border with Bangladesh. The Sundarbans are a UNESCO world heritage center–the largest mangrove forest in the world. A land of islands, subsistence fishermen and Bengal tigers, where people and wildlife are already feeling the impacts of rising seas.

Here on this Tumblr, we’ll bring you photos and observations throughout our journey. You’ll get a glimpse of our reporting before it appears on the radio and npr.org. We’ll also be posting on twitter, facebook, and instagram, with the hashtag #ATCinIndia. Matt and David are on the ground already. I arrive later this week. Thanks for joining us on this project!

Magnets Mean Your New Refrigerator Will Make History

by Michael Keller

Coming soon to a kitchen near you—magnets in your refrigerator. And we’re not talking about slapping your kid’s artwork inside the fridge next to the milk and butter.

It’s the next generation of residential food and drink cooling, and it’s powered by magnets. Gone will be the almost century-old unit in your kitchen that uses a heat-transfer process based on liquid refrigerants called vapor compression refrigeration. Condensers and refrigerants will be replaced with magnets and special alloys that get hot and cold based on their proximity to magnetic fields. The technology could also be used for air-conditioning.

Magnetic refrigeration, proponents say, is a rapidly approaching technology that will amount to a revolution in domestic energy use.

“It’s the equivalent to a gas-powered car moving to electric—that’s the kind of leap we’re making in refrigeration,” said Ed Vineyard, a senior researcher at the U.S. Department of Energy’s Oak Ridge National Laboratory. Vineyard’s Building Technologies Program has teamed up with GE to bring magnetic refrigeration to the public in around five years.

In India, incomes have tripled in just the last 10 years. Ah, but who cares about those, um, 2.5 billion people? You do! Weren’t we just wishing for a Star Trek-style utopia where all of humanity is one? So we should be celebrating the golden wave that is lifting China and India out of poverty the same as if it happened to us, right? We’re all members of the human family.

And make no mistake, the economic slump us Americans and Europeans are grinding through is, ultimately, due to the fact that the rest of the world has finally been invited to the party. Fuel gets expensive because demand goes up, because people on the other side of the world are able to own their first cars, air conditioners, and computers. Good unskilled jobs are hard to come by because people in developing countries are competing for what are to them the first good jobs of their lives.

In other words, the rich man did give up his fortune to help the poor. It’s just that we’re all that rich man. If you have a home with a computer, a refrigerator, and air conditioning, then you’re in the top, upper crust of the world’s living standards. You’re living the Emily Ratajkowski life – the one everybody else wants. So does that give you a warm feeling in your heart knowing that your loss is their gain?

If not, why not?

7 Reasons the World Looks Worse Than It Really Is

How does a refrigerator generate cold?
— 
  1. The compressor squeezes the refrigerant (inside coils and tubing) which is in a vapor state - this raises its temperature, then pushes it into the coils on the outside of the refrigerator.

  2. The hot gas in the outside coils cools down to the air temperature of the kitchen.

  3. The refrigerant flows into the coils inside the freezer and the fridge - as it flows, it expands. This pulls heat from the refrigerator interior.

  4. The refrigerant expands, absorbs the heat from inside the fridge, cooling down the air.

  5. It then flows back to the compressor, where the cycle starts all over.

Interesting fact: Refrigerators, freezers and air conditioners actually generates heat, not cold.

A motor is used to MOVE heat from one place to another, plus the motor gets hot while it’s working.

Put a bunch of running freezers in a room, and the room will get hot. Open the freezers, and it will get even hotter.

If this is hard to get your head around, think about this: “Cold” does not actually exist. Heat is energy, cold is simply “less heat”. You cannot create negative energy, you cannot destroy energy. But you can move it.

/u/myplacedk + /u/pdx_stan

I pick up toenails and paper clips, and anything
that taste old and eighty.
Forgotten pieces of people who ran too fast
their lungs cannot fall asleep without breathing
refrigerator air. Failing,
every time they glue parts of themselves
without breaking into a thousand more.

I hold out my hand, keeping the pieces near my chest
as though I am a jewel thief stuck in traffic.
Then I will call the cops instead.
Tell the story I heard
about a man who lost a wife one night
when he came home with bullets for teeth,
his words running like wildfire.
Tell them
about a girl who folds herself
into a hundred pages too long to read
for people who cannot see her worth.
Tell them
the story I see in every falling leaf
from the arms of a mother
who carries the weight of the world in her belly.

And hope they will listen.
Maybe even record the ones that was spoken to me
in tears and how I told it
with the same waterfall,
make them remember how it feels like
to have pieces of yourself forgotten
because no one else seems to remember them
at all.
