Description of SPT SF-610 Portable Evaporative Air Cooler with Ionizer
This Evaporative Air Cooler, Humidifier, and Fan is versatile, lightweight and economical. The Cooler easily rolls from room to room for use anywhere in your house or office. This Air Cooler shoots a stream of air with oscillating louvers, to evenly distribute refreshing cool air. Can also be used as a fan or humidifier if temperature is not an issue. - plus get the air cleaning benefits of the ionic air purifier. The remote control allows you to easily change settings. The Air Cooler works by endothermic reaction (a reaction that consumes heat), so this evaporative Air Cooler sucks air through a wick saturated with water. As the air flows through the wick, some of the water evaporates into the air, consuming the heat that was in the air. An air stream is then blown out the front of the unit and is considerably cooler than the current room temperature! This is not an air conditioner and therefore uses much less energy. The unit works well in dry climates; not very effective in areas with high humidity as the unit utilizes water to cool.Tools and Hardware Reviews of SPT SF-610 Portable Evaporative Air Cooler with Ionizer
Customer Review: Best used as a personal cooler
Summary: 4 Stars
As I type this, it's 103 outside with 29% humidity. Inside, without the central air conditioner running, it's 102 and 30% humidity. I filled up this gizmo, turned it on, and the air coming out the front of the unit is 91 with 45% humidity.
Since this cooler works by the phase-change of water into gas, you'll need to open your windows and let the air circulate so the humidity doesn't build up to the point where you're in a sauna and start to sweat like--um--someone who's in a sauna.
It won't cool down an entire room, but if you'll be typing away on your computer like I am, you'll be sitting in one place. So sit next to the cooling breeze with an iced tea, and you'll be happy as a clam.
Here's some numbers for how it works, and what's reasonable to expect from this cooler . . .
Everyone knows that to generate steam, you apply lots of heat to water. You'll be happy to learn that if you dip a towel in water and hang it to dry, the liquid water changes to vapor, and in the process absorbs heat. How much heat, you ask?
Water weighs about 8.3 lbs per gallon. To turn one lb of water to vapor, you need to apply about 910 BTU of heat. Multiply 910 times 8.3 and you get 7553 BTU. So, if you can entice a swamp cooler to vaporize one gallon of water in one hour, it will (about) cool as much as a regular window unit rated at 7500 BTU.
However, this particular machine professes to vaporize about half a liter of water (about one pint) in an hour. One pint is 1/8 of a gallon, which is about one lb of water, so you can assume this machine will cool at the rate of 900 BTU per hour, which is about 20% of what a small window air conditioner will provide.
Nevertheless, this evaporative cooler is much more energy-efficient than a plug-in AC unit.
This cooler draws 60 watts of power. Compare to a window AC unit, which draws about 20 times as much power (1200 watts and up).
If electricity costs you 10 cents per KWH:
This cooler will operate for 160 hours (a whole week) for $1.00
A window AC unit pulling 1000 watts will operate for 10 hours for $1.00
Consider what you need to cool before you choose a cooler.
If it's just you, and you're not too fussy about sitting next to what's essentially a fan with a bit of cooling power, this will do the trick. But if you need to cool an entire room from 100 degrees F to 85 or below, you'll absolutely need a regular air conditioning unit.
One other note . . . using ice will help a bit, but not by a whole lot, because
to melt one lb of ice, it only takes about 140 BTU of energy vs. the 910 BTU it takes to vaporize water. So you get 6 times the benefit of vaporizing water compared to just melting it. No doubt it helps, but don't worry too much about it, unless you happen to work for an ice-making company and have lots of free ice available.
Bottom line -- I'm happy; it does what it needs to do, because it's just me sitting next to my PC. And it's way more affordable to me, and much easier on the environment.
