Frequently Asked Questions:
Why Are Landfills Bad For The Environment?
Organic substances “biodegrade” when they are broken down by other living organisms (such as enzymes and microbes) into their constituent parts, and in turn recycled by nature as the building blocks for new life. The process can occur aerobically (with the aid of oxygen) or anaerobically (without oxygen). Substances break down much faster under aerobic conditions, as oxygen helps break the molecules apart.
Landfills Too Tightly Packed for Most Trash to Biodegrade
Most landfills are fundamentally anaerobic because they are compacted so tightly, and thus do not let much air in. As such, any biodegradation that does take place does so very slowly.
What About Cars Air Condition?
Does Settings On Your Cars Ac Have Any Effect On Gas Mileage Or Is It Just On Or Off. Like If I Turn Up The Temp Will That Save Any. Or If I Have The Fan On High Will That Make It Use More Than If The Fan Is On Low. I Already Know That Max Air Re-Circulates.
No it makes no difference what so ever it is either on or off.The most effecient way to run the a/c in your car is on the max/recirculate setting.This setting recirculates the air from the cars cabin.It is more effecient since your are not cooling outside(hot) air.As far as mileage the only way to save gas with it is not to use it,the compressor is either energized or not so adjusting the temperature will have no effect.The fan setting does however change the amount of electricity required to operate the fan in turn causing more load on the alternator but this is pretty insignificant also.
The best way to save fuel is keep your cars maintenance up and watch your driving style don't be sudden or jerky with accelerating or stopping. and try to drive fluid, smooth and steady.
How Is An Air Condition Unit Work?
Freon is pumped using a compressor that has a high pressure. High-pressure Freon flowed in freely cooling unit so that it has a much lower pressure. Because freon pressure change from high pressure to low pressure so that the heat absorption occurs refrigeration unit to cool.
Outside air is passed through the air conditioning unit so that it becomes cold .
When Was Air Conditioning Invented?
I Grew Up In Fl With Ac And I Never Was Very Affected By Heat. Now It Seems, I Walk Around On A Summer Day And I Cant Spend Much Time In The Heat, I Always Feel Like I Could Pass Out. I'M So Anal About It In The Summer That I Need To Know If I Go Out To A Place If It Has Ac Or Not. It Got Me Thinking About How People Did It Before It Was Invented.
First of all, let's be real careful to differentiate between evaporative cooling (which many people consider to be part of the Air Conditioning world) and refrigeration type AC.
Yes, it was Willis Carrier in 1902 who invented refrigeration type AC but it was largely experimental, prototypes and special case projects until the 1930s. During those early years, every application was a custom design system, including the power to support it.
In the mid-30s, it began to get standardized and installed into stores, homes and a few office buildings. The world was still reeling from the Depression, though, and there weren't a lot of installations. What happened next was the whole story of WWII. The Carrier operation could not get the materials, had to do other wartime defense manufacturing, etc and so on.
After WWII, it was like the world discovered Air Conditioning and everyone had to have it. Meteoric rise, etc and so on. CARRIER is still the premier manufacturer of air conditioning units in the world.
All of that historical stuff and Roman baths was before refrigeration type AC. It is largely evaporative type cooling which, in answer to your query, was a lot of how people got by in those days. Lots of fans, shade, mint julips and, if they were wealthy, evaporative cooling. And, they didn't walk around in the heat; they worked around the hot part of the day. Heat stroke was just as serious then as it is now.
How Does Air Conditioning Work?
Most commonly with a compressor and a refrigerant like Freon.
The refrigerant is compressed, which makes it hot. Then it is cooled by passing it through a heat exchanger where air is blown over it. That's on the outside of the building - the refrigerant is hotter than the outside air.
Then the now-cooled (but still warm) refrigerant is passed through a nozzle and allowed to expand. That makes it cold, and it's passed through a second heat exchanger on the inside of the building, where it cools the air. Then it's fed back to the compressor.
Since cold air can hold less moisture than warm air, water condenses out onto the cold heat exchanger coils where it is collected and drained outside. So the air conditioner also dries the air.
