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?

Simpler than a weather vane, you just lick your finger and hold it up to check which way the wind is blowing.

How did the ancient Egyptians employ evaporative cooling?

Smart crowd, those ancient Egyptians. They'd hang up wet cloths and blankets and the air would cool down as it passed through them.

What do they call evaporative coolers in the U.S.?

Evaporative coolers are usually referred to as swamp coolers in the U.S.

What would be considered optimum weather conditions for a swamp cooler?

Swamp coolers work best under hot and dry weather conditions.

What does Benjamin Franklin have to do with evaporative cooling?

Franklin came across the notion of evaporative cooling by chance. He went on to conduct experiments on it.

What is the basic principle of a swamp cooler?

A swamp cooler draws in outside air, draws it by means of a blower across wet pads and expels cool air.

How does evaporation play a part in swamp cooling systems?

Evaporation takes place at the surface of a liquid, such as water, where molecules escape into the air, drawing heat from the air and at the same time lowering its temperature and that of the liquid.

What is meant by wet bulb temperature?

This is the temperature taken by a thermometer wrapped in a wet cloth, which tells you what the air temperature would be at 100 percent humidity. This temperature is always lower than that of a dry bulb thermometer.

What happens when you leave the door or window open with swamp cooling?

Unlike conventional air conditioning, which requires a closed area, the intake of outside air actually optimizes the swamp cooler's efficiency.

Do swamp coolers have a drain pipe or drip pipe as air conditioners do?

Air conditioners dehumidify the air and therefore need to drain the humidity in the form of distilled water. Swamp coolers boost humidity and therefore don't need a drain pipe.

What is the relationship between a swamp cooler and the skin's perspiration?

You get the added effect of the two combined. You feel cooler because of the evaporation of water-laden air from your skin.

Do swamp coolers use ducts to spread the cool air around?

Usually, swamp coolers don't use ducts; if they did, they'd need larger-than-ordinary ones. Instead, cool air is spread through door and window openings.

According to the U.S. National Association of Home Builders, purchasing and installing a swamp cooler costs:

A swamp cooler, fully installed, costs between $700 and $1,000, significantly less than air conditioning.

How do running costs compare between a swamp cooler and conventional air conditioning?

There's no doubting these figures: Use a swamp cooler and you'll spend about one third of what air conditioning would cost.

Advertisement

Are swamp coolers better for the environment than air conditioners?

Much better. While air conditioners use chlorofluorocarbons or, at best, hydrochloroflurocarbons, swamp coolers use no ozone-depleting chemicals.

What are the basic parts of a swamp cooler?

The average swamp cooler requires very basic parts: a blower, pads, a pump, water and a container.

Advertisement

What is the effect on a swamp cooler with a wet bulb temperature of above 70 degrees Fahrenheit (21 degrees Celsius)?

The swamp cooler loses its cooling effect when the gap between wet and dry bulb temperatures is low. Thus, it will struggle to keep the temperature at a comfortable level.

Advertisement

What is the recommendation of the U.S. Environmental Protection Agency regarding ideal home humidity levels?

The EPA recommends an ideal humidity level of between 30 and 60 percent, low enough to keep mold to a minimum.

How much water does a swamp cooler require per hour?

A swamp cooler needs between 3.5 and 10.5 gallons (13.25 - 39.75 liters) of water per hour to operate.

Using a simple evaporative cooling method, tomatoes were found to keep fresh for how long?

This method was demonstrated in Sudan, where tomatoes were found to last up to 20 days under evaporative cooling conditions.
