chill wind  -  air and water swamp cooler
You know it's coming: it was already hot and unbearable at 7 in the morning that summer. m.
The asphalt softens and gives off heat in the visible waves.
In the car, even worse, the steering wheel is almost too hot to touch.
But after a few minutes on the road, the explosion from the vent began to get colder, drier and colder. . . ahhh.
As anyone who has endured regular power outages in an office without air conditioning or at home can attest, climate control can be an important part of maintaining sanity throughout the summer.
It kept us at the temperature: We decided whether it was a pleasant 75 or a cold 69 would make us sleep better.
It's just that there's a lot more than we might realize that we can't control the air conditioning in the end. It controls us.
Since the advent of air conditioning in the early last century, it has changed the way homes and offices are built, where Americans live, and how they commute.
In his new book, lose our calmness: the truth about the discomfort of our air --
Condition world (
Find a new way to spend the summer)
Stan Cox, an environmental and political writer, believes that this seemingly necessary thing consumes a lot more of our resources than we think.
Cooling costs in the United States dwarf heating costs;
Overall, the United States uses as much power per year with air conditioners as with all air conditioners across the continent.
With the attention of the rest of the world-
India, in particular, is an emerging air-conditioning market. -
No one knows what the consequences will be.
Cox suggested that we can get rid of the air conditioning, spend more time outdoors, cool people, not cool the space, and be willing to find comfort in a slightly colder situation.
Cox spoke to ideas by phone from his office at the Salina land Institute in Kansas.
Idea: How do we get into this attachment state of air conditioning?
Cox: houses and office buildings that rely on natural ventilation have changed.
Many more expensive features such as House, heavier eaves and loft fans, heavier buildings, crossover when deciding to install air conditioning
Ventilation, all these things can be used, you can have what Forbes magazine calls "TV"
Hot Box.
"You can build more versatile houses at a reasonable price and have central air conditioning.
With the office building, you can make these big cubes, where the very cheap interior space will be comfortable.
Idea: now it seems that most people feel a bit out of place to open a window.
Cox: at my workplace, we are building a new building and we are trying to make it energy efficient, so there is a lot of discussion about being able to open the window.
People decided that some automated systems were needed because people were reluctant to operate manually.
Idea: some of the hottest places in the United States, especially Florida and the Sunbelt, are now one of the most populous places.
Cox: Phoenix is going to get to a point where, from a shortage of energy or water or both, it can't exist in its current form.
. . . . . . I was in Phoenix and learned about the Hohokam civilization that existed between 450 and 1450.
So for 1,000 years, there have been many people living in Phoenix.
One reason they are able to do this is that the heat has been more alleviated due to rivers, canals and vegetation throughout the year.
There is almost no water now, and air conditioning makes it possible to increase the population, which means Phoenix is actually getting hotter.
The temperature has risen by seven degrees in the past 50 years.
Idea: why not legislation to improve the efficiency of air conditioning?
Cox: the efficiency of air conditioning has increased by 28% in the past 12 years, so this is a good example.
However, during that time, the power of air conditioners used by ordinary air-conditioned families increased by 37%.
A large part of this increase is related to the increase in square feet of new homes and the continuous conversion of room air conditioning to central air conditioning.
Ideas: There are many examples in the book that show that use will increase as efficiency improves.
Cox: One of my friends said efficiency is like selling energy, what do you do when things are selling?
You buy more!
Idea: So, if people just make the weather colder and colder, where is the hope of changing these habits?
Cox: there is a lot of interesting work on "comfort Research. . .
One of the things that I think is most interesting is the so-called comfort adaptation model, which says people tend to find a comfortable temperature range and humidity range that is not a fixed range, as defined in various manuals, but it depends on what kind of temperature people have experienced in the last 30 days.
Not only do people like the warm temperature range, they also like the variety if they are warm recently.
Idea: Is there a replacement for air conditioning?
Cox: The key for most people is to use air conditioning more efficiently, or less.
I think it is the most fashionable thing to use solar energy, although it is expensive.
You can do this as long as there are enough photovoltaic panels to run a normal air conditioner, but there are also so-called absorption methods.
They use the different boiling temperatures of liquid, water and lithium, and other things, use the heat of the sun to produce chilled water and cycle through buildings. . . .
On top of that, for something like a green roof, there are some very good tips and improved techniques where you can plant vegetation on the roof, which will not only cast a shadow over the roof, but also
Idea: What would you tell someone without this technology?
Cox: some of the best technologies do include air flow. -
That is, good old man. fashioned fans.
A lot of people either remember or are still using things like whole --
House fan, once the temperature drops, it can breathe cold air into the house very well.
Or in a dry climate, evaporation cooling technology is used when there is sufficient water supply.
As you walk through the old community of Phoenix, you will see an old evaporation or swamp cooler on the top of almost every house.
Idea: you did find someone who is not a fan of air conditioning
Cox: The favorite sentence I met in reading and talking to people was a woman from Davis, California.
"We don't use the air conditioner because it makes it too hot outside," she said.
"It has a double meaning in terms of the impact and how it makes you feel.
It's really hard to get from the cold inside to the heat outside, and if we're going to be more adaptable, resilient, and heat-resistant, what we need to rethink is the indoor climate, not the outdoor one. J.
