How cool are you? When the summer sets in and you feel hot and sticky, what's the best method for cooling off? Should you opt for a standard air conditioner or take a chance on a swamp cooler? Take this quiz and see whether swamp cooling is for you.
Which of these is a simple example of evaporative cooling?
perspiring a lot after a long mountain climb
wiping the wet tears off your face with a tissue
holding up a wet finger to test for wind direction
How did the ancient Egyptians employ evaporative cooling?
They would hang wet blankets across their doors and let the air blow through.
They used to tie wet garlic cloves up high, which would cool the air down.
They used to blow air from their lungs through wet towels.
What do they call evaporative coolers in the U.S.?
evaporative air coolers
swamp air coolers
What would be considered optimum weather conditions for a swamp cooler?
hot and dry
What does Benjamin Franklin have to do with evaporative cooling?
He drew the first sketches of early evaporative cooling systems.
He experimented with it using a thermometer, spirits and air.
He used an early evaporative cooling system while writing his monumental works.
What is the basic principle of a swamp cooler?
It takes air from the outside, blows it through wet pads and cools down the inside air.
It draws in outside air, dehumidifies it and cools down the air inside.
It blows air through a blower and releases it to the outside once it has cooled.
How does evaporation play a part in swamp cooling systems?
Air particles heat up, evaporate into gas state and bind with cooler air particles to cool the inside temperatures.
Water is converted into gas form, which releases heat particles into the surrounding area.
Water releases molecules into the air, drawing in heat from the air.
What is meant by wet bulb temperature?
the temperature of a wet light bulb, at zero percent humidity and no electric power
the temperature of a wet thermometer bulb
the temperature at which a wet thermometer bulb reaches its maximum evaporative state
What happens when you leave the door or window open with swamp cooling?
You don't succeed in cooling your home.
You maximize its efficiency, because it needs air circulation.
You put the system in jeopardy, which might necessitate regular repairs.
Do swamp coolers have a drain pipe or drip pipe as air conditioners do?
No, because there would be nowhere to attach the pipe.
Yes, they have similar ones.
No, because they humidify the air, whereas air conditioners dehumidify.
What is the relationship between a swamp cooler and the skin's perspiration?
The swamp cooler causes you to perspire more.
The boosted air humidity, together with skin perspiration, makes for a heightened feeling of coolness.
You don't feel your perspiration because you're so cool.
Do swamp coolers use ducts to spread the cool air around?
Yes, otherwise the cool air would be contained in one area.
Mostly not, since they'd have to be larger than air conditioning ductwork.
It depends on the installation requirements.
According to the U.S. National Association of Home Builders, purchasing and installing a swamp cooler costs:
$700 - $1,000
$1,000 - $1,300
$1,000 - $1,700
How do running costs compare between a swamp cooler and conventional air conditioning?
Air conditioning costs about one third the operating cost of swamp cooling.
Swamp cooling costs about one half the operating cost of air conditioning.
Swamp cooling costs about one third the operating cost of air conditioning.
Are swamp coolers better for the environment than air conditioners?
Not by a significant degree.
Yes. They don't use ozone-depleting chemicals.
Yes. They use less hydrochlorofluorocarbons.
What are the basic parts of a swamp cooler?
blower, pads, pump, water and container
blower, pads, metal grates and water catchment tray
fan, rotation blades, pump, air humidifier
What is the effect on a swamp cooler with a wet bulb temperature of above 70 degrees Fahrenheit (21 degrees Celsius)?
It will increase the humidity level by 50 percent.
It will work harder by blowing more air through the blower.
It won't be able to keep the temperature at a comfortable level.
What is the recommendation of the U.S. Environmental Protection Agency regarding ideal home humidity levels?
between 15 and 40 percent humidity
between 20 and 30 percent humidity
between 30 and 60 percent humidity
How much water does a swamp cooler require per hour?
1.5 - 3.5 gallons (5.67 - 13.25 liters)
3.5 - 10.5 gallons (13.25 - 39.75 liters)
7.5 - 10.5 gallons (28.39 - 39.75 liters)
Using a simple evaporative cooling method, tomatoes were found to keep fresh for how long?
