What you didn’t know about air-conditioning

I am not a big fan of air-conditioning but in some parts of the world you just can’t survive without it. There is no doubt that the invention of air-conditioning is considered to be one of the most important achievements in the twentieth century and has hugely impacted the world. Despite the fact, that the air-conditioning is just here, quietly humming, you probably don’t know much about it.

Basic facts about air-conditioning

Willis Carrier

The first modern air conditioner was Willis Carrier in 1902 for a publishing company in Brooklyn. Temperature and humidity were kept low so paper didn’t contract or expand. The air conditioner wasn’t intended to be used for comfort.

Each air conditioner has four basic components : pump, evaporator, condenser, and expansion valve. Most of air conditioners start out as a raw material in the form of steel shapes and steel sheets. When the sheet metal is processed into fabrication, it is cut, punched, formed, drilled or bent into am useful shape or form. It is made of galvanized sheet metal that uses a zinc coating providing a protection against corrosion.

All air conditioners have four basic components: pump, evaporator, condenser, and expansion valve. Hot refrigerant vapor is pumped at high pressure through the condenser, where it gives off heat to the atmosphere by condensing into a liquid. The cooled refrigerant then passes through the expansion valve, which lowers the pressure of the liquid. The liquid refrigerant now enters the evaporator, where it will take heat from the room and change into a gaseous state. This part of the cycle releases cool air into the air-conditioned building. The hot refrigerant vapor is then ready to repeat the cycle.

Interesting facts about air-conditioning

  • the first public places having air conditioners were movie theaters. During hot summer days, these theaters were the coolest places in town so you can probably imagine those crowds. Studios started to release their best productions in the summer and that’s how modern summer blockbuster  was born.
  • each year United States uses the same amount energy for powering the air conditioners as Africa uses to power the entire continent.
  • the introduction of air-conditioning actually lowered the natural human tolerance for heat.
  • the first building using the air-conditioning was The New York Stock Exchange Building in NYC in 1903 designing and building houses was changed after air conditioner was introduced. Brick structures with high ceilings, porches, breezeways that provided shade for cooling occupants are gone.

Shanghai Metal Corporation uses air conditioning for cooling employees and at the same time sells galvanized steel, steel sheets and other high-quality metal products.

Be cool, save energy and pay less

While building a house there is always a question what kind of roof to choose, what colour, should it be flat or pitched. When you live in a hot climate the answer is clear. A metal cool roof!

Diagram_1_-_SR_and_TE
A diagram

A cool roof can reflect sunlight and cools itself by emitting the radiation to its surroundings. Isn’t that cool? The roof literally reduces the amount of heat. Two basic characteristics of the roof are solar reflectance and thermal emittance. It is like wearing a white t-shirt on a hot day, it reflects more sunlight and absorb the heat.

 Benefits
  • reducing energy use – as a building stays cooler, it uses less energy for air conditioning
  • reducing greenhouse gas emissions and air pollution
  • improving human’s health and make them feel comfortable – cool roofs prevent heat-related illnesses and deaths
  • extending roof life and lowering roof maintenance costs

metal_roofMetal cool roofs might be one of the solutions for polluted cities. They have significant environmental benefits besides using cool roofs cool the cities. Increasing workplace productivity and decreasing pollution can be achieved by using metal cool roofs. Cool metal roofs actually last longer than standard ones because a cool roof doesn’t heat up that much.

What’s more cool roofs are typically light in colors so they can perfectly be a part of the architecture for those who might consider it as an important feature. As today’s range of cool roofs is pretty wide and there are a lot of manufacturers, it can be a real challenge to make a good choice.

Shakespeare Reborn in Container Theaters

We cannot all be masters, nor all masters cannot be truly follow’d.                   –Quotation from Shakespeare’s Othello

The modularity of shipping containers enables creative architects to design beautiful container homes and hotels. Open top containers can be turned into swimming pools. Open side containers can become excellent theaters.

OA

In 2013 a local architecture studio O+A designed the architectural setting of the 20th Over het IJ Festival and transformed Amsterdam’s shipyard into a huge restaurant area with theatrical stages. The building of the “container city” took four days, and another two days to take down, lasting only two weeks in between.

por_dinero

Shipping containers theaters have also been used in Miami. In 2012, the actors of Microteatro por Dinero  performed in 15 minute short dramas for 15 people six times a night in a shipping container. The concept of “por dinero performance” (in English for money) has its roots in Madrid where local actors turned an old bordello into a commercial mini theater and spread the word in social media.

container_theater

Besides drama, shipping containers have also been used as movie theaters. Container mini theaters showed short films in New York in 2011. The event was a part of USA Network’s Character Project and it also was supported by the director of the Alien Saga, Ridley Scott. Audience was placed in 18-seat air conditioned screening pods to watch the shorts. The tour also took place in Los Angeles, San Francisco and Chicago.

Character-Project-Container

It is yet unclear when does this “Broadway in a box” concept spread globally and go mainstream. Still, because of these events, mobile mini theaters will gain popularity in cinema and drama industries.

The Cure that Lowers Aggression Caused by High Temperatures

Many philosophers, writers and narrators have for ages shared a common belief that hot temperatures increase violence and aggression. Even in the English language we use expressions such as “hot tempered” or “hot headed” to describe the character of an aggressive person. Scientists have also been interested in this connection for years, and through various studies, they have also found evidence for the correlation.

cooling_down

Many laboratory, field, correlational and archival studies give an unanimous result: hot temperature causes violent crimes. The emphasis is on the word violent, because contradictional  studies show that crimes also do occur in lower temperatures but they are most commonly non-violent. Also archival studies show that when the weather is hot e.g. a baseball player is more likely to hit the pitcher with a bat (source).

angrycarlos

Still, the correlation between high temperature and violence is not flawless. For instance, what if everybody stayed at home on a hot day? Wouldn’t that prevent at least some occurrences of violence? Time is also a critical factor in this sense. Most of the violent crimes occur during the time when masses of people are most likely to engage in activities at the same time. In general, when a third variable changes the correlation between two variables so remarkably, we are talking about the Simpson paradox. In this case time changes the situation so that the relation between temperature and violence needs some modification.

Its-too-hot-today-300x300

Scientists have redefined the correlation and state that when the temperature rises above an uncomfortable level, the probability for aggression and violence rises as well. Therefore it is really important to ensure that especially public places such as schools,  shopping malls and even prisons have an enhanced air conditioning system. A research also shows that drinking cold beverages will decrease the probability of becoming angry (source).

drink

Especially today, during the times of increased global warming, it is really important for countries and cities to keep their citizens cool. Today when we discuss global warming, the emphasis seems to be on natural disasters or effects on agriculture. What we are very likely to forget that because global warming raises temperatures, the crime rates will also increase. Most global warming experts predict that if temperatures rise between  2°F and 8°F (1.1°C to 4.4°C) the rates of violent assaults will also increase by approximately 80,000 annually.

pigeon

A new business idea for areas suffering from global warming (which by the way means everywhere on the planet) is to establish pop-up cooling rooms, places where temperature is substantially low and where people can spend a short time to cool down. This can be easily implemented with refrigerated shipping containers whose temperature can decrease drastically (on extreme even below zero). In order to decrease crime rates and increase public safety we really need to keep even the common people cool and prevent their blood from boiling.

Live Clean Or Die Hard

We’ve all seen the pictures of extreme air pollution around China. And the UK had its time in the smog, with the Great Smog of 1952 where it was so bad people died.

Heavy Smog Hits East China

However, the EPA (US Environmental Protection Agency) conducted a study that showed the air quality in the average home is up to five times dirtier than the air outside. Luckily, there is a pretty easy way for improving the indoor air quality of your home – have clean air ducts. Yes, your house has air ducts, just like all the buildings in those blockbuster action films everyone’s seen, only yours are too small for you to play spy in.

airduct

Over time, and especially with use, dust and debris start to build up. But they’re not the only things; mold, insects, and even rodents tend to inhabit these tiny passageways, allowing your central air and heat system to spread their filth around your house like they own the place. Needless to say, this can have a largely negative impact on your health.

By getting your air ducts cleaned and your air conditioning maintained and replaced regularly, say once or twice a year, you can do your part to help ensure that it’s healthier for you to breathe inside instead of outside.

Imagine a Summer Without Air Conditioning

Picture this: It’s 35°C, there’s no air conditioning, and you’re packed into a subway of sweaty people. The last generation doesn’t need to imagine in –they lived it.

sweaty2

Before AC, most industry traditionally slowed or stopped in the summer, when buildings were hot and workers were sluggish. Back then, many workers around the world got month long August vacations similar to what workers still get in Europe today, where AC isn’t as popular.

sweaty3

The development of effective temperature control and refrigeration has revolutionized almost every aspect of industry. Without AC, the following things would be virtually impossible: the manufacture of computers and chip sets; data storage centers; the production, delivery, and storage of food; pharmaceutical manufacturing; and chemical manufacturing.

aircon2

AC allowed for exponential advances in medicine and human life expectancy. Air-conditioned hospitals helped defeat malaria, decrease infant mortality, inhibit bacteria, and advance developments in surgery.

airconditioner1

So the humble AC has been life changing, and not just on our comfort levels.

Shanghai metal produces the stainless steel tubes for electric climate products. High-temperature resistant wire is distributed evenly in the stainless steel seamless pipes, while good quality crystallized magnesium oxide powder is filled in the gap. As a result, the heater has not only a sophisticated structure, but also high efficiency. To find out more, please visit our websiteLinkedInTwitter, and Facebook.
