Chillmax Air Go - Portable, take-anywhere personal cooler

Product Information

However, this is where the problems come in for the Chillmax and similar devices. If it’s 35ºC and 40%RH, it’ll feel like 37ºC. Cool the air to 31ºC but send the humidity up to 80%RH, and it’ll feel like 41ºC. So it’s actually hotter in terms of comfort. Do the same comparison when the surrounding temperature is 38ºC, and the ‘feels like’ goes from 43ºC to over 50ºC! As an example, if the air temperature is 30ºC and 50%RH, it will feel like 31ºC, but if the humidity goes up to 80%RH, then it will feel like 38ºC – even though the thermometer still tells you it’s 30ºC. Until August 2021, the answer in relation to the ChillMax was no. However, I saw an advert (as shouty as usual) for the InstaChill tonight. Unlike the ChillMax, which is the size of a small table top radio, the InstaChill is the size of a bedside cabinet. And you can certainly get larger evaporative coolers from other manufacturers. The working principle is identical, except that the larger the surface area of water, and the greater the airflow over that water, then the greater will be the possible drop in temperature at the front end (and the more moisture being pumped out to increase the humidity). However, cooling effectiveness is influenced greatly by the RH of the air going in.

There are many, many more. And in every case, the relationship with humidity is the key. If it is already humid, evaporative coolers do not work and actually make things worse. Chillmax Go Fan is a little powerhouse of cooling technology. Designed to hold the maximum power in the smallest space, the clever engineering means you get a powerful, cooling performance with a fan you can hold in your hand. Thanks to the Lithium Ion technology that draws far more power than standard batteries and converts it into a level of energy that lets our smart, compact motor generate so much power you’ll feel like you’re stood in front of a full-sized wall or ceiling fan! Adjustable 360° smart-spin technologyIt does cool the air by a few degrees, so in that sense it works. However, it also sends the humidity up, and in most cases that actually makes you feel hotter and more uncomfortable. In that sense, it doesn’t work.

It might – while you’re blowing air over ice. But once they defrost, which will happen in a few minutes in the temperatures you’ll likely be experiencing, then no. You’ll also have more condensate to deal with from the melted ice pouring out of the front grille. At lower temperatures the Chillmax will produce a slight net cooling effect. But if the air temperature is above about 30ºC (and 50%RH) – which isn’t excessively hot or humid to start with, though it is around the point where you would start thinking about cooling things down – it’ll actually make you feel warmer. And if it is already humid outside, you’ll feel hotter still. The calculation for this is complex (you should see how long my Excel formula for it is). It is non-linear, and the increase in ‘feels like’ is greater at higher temperatures. It also contains an element of opinion/perception, which is why there’s no point using numbers above about 60ºC. But the ‘Heat Index’ is what forecasters use. Incidentally, the official health designations for the colours are: yellow – caution; amber – extreme caution; orange – danger; and red – extreme danger. Vulnerable people need to take these into consideration before going out in hot weather. The term ‘humidity’ usually refers to the absolute humidity, which is amount of water in the air. However, the figure most people are referring to is the relative humidity. This is the amount of moisture in the air expressed as a percentage of the maximum amount it could hold at that temperature, hence the units %RH. It’s a complicated subject, but the important factor for us here is that when it is warm or hot, higher absolute humidity is uncomfortable because the amount of moisture in the air relative to the maximum possible is higher. Indeed, you may have seen weather forecasts where they give the actual temperature and the ‘feels like’ equivalent – that’s a reference to the ‘ Heat Index’, which takes into account the effect of the %RH. Here’s a graphical chart for that. The HUGE difference between Chillmax Air Go and a fan is that a fan simply moves air around so the moving air you get is the same temperature as the room! Why push warm, dry air around when you can cool it down and humidify it first? Like a standard, bulky air-con unit, Chillmax Air Go actually takes the air in your room, or outside, and through evaporation, lowers its temperature. This way you get cooler air, but it’s also been humidified, so no more dry, burning sinuses when you’re trying to sleep. With Chillmax Air Go you’ll get measurably cooler air coming right into your personal space that isn’t dry! Portable design, just charge the fan and take it anywhereSomeone found this article on the search term “jml chillmax air for pc cooling”. No. Blowing damp air into your PC would be dangerous, potentially expensive, and would only gain you 4ºC at best. These are the data for relative humidity recorded at the same time as the temperature measurement, above (the red line is where I moved the logger). The humidity went up dramatically – a jump of about 30%RH. I fired up my trusty data logger and left it in front of my desk fan for 30 minutes for the control data. Then I powered up the Chillmax and moved the logger in front of it for the same period of time. This is what it recorded (the red line is where I moved it). Chillmax Air turns cold water, via a special filter, into a finer mist of cool, refreshing air circulated by a fan with three speed settings. It humidifies while it cools your personal breathing space so you can stay cool and breathe moist, humid air wherever you need it.

As I’ve already explained, the Chillmax works by evaporating water on fibrous panels by forcing air across them. That water has got to go somewhere, and in this case it comes out with the cooled air as water vapour. In the right light, you can actually see it – it’s essentially fog, so the cooled air is also moistened. And just like when it’s foggy outside, and everywhere gets damp, this water vapour can condense on cooler surfaces. My data logger collected some and began to drip during the test, and I have since discovered that it also condenses on the front grille and can drip periodically, so you’d need to be careful what you had underneath it if you placed it on a shelf. The fan is quite powerful enough to project the drips forward slightly when they drop. Early in July 2019, I saw the Chillmax Air advertised on TV in one of those shouty JML ads. That same evening, I was shopping in Asda and saw it on display. I am an idiot for things like this, and bought it on impulse so I could test whether it worked or not. For the following locations next day delivery may take up to two working days: Aberdeen (AB 30-35, 41-54), Northern Highlands (AB 36-38, 55-56), FK (17-21), HS (1-8), IV (All), KW (0-14), PH (15-32, 34-48), Eire (Republic of Ireland) (EI (ZZ75) (All)), Glasgow (G 83), Guernsey (GY 9), Oban (HS 9, KA 28, PA 20-99, PH 33, 49-99), Isle of Man (IM (All)), Arran (KA 27), Orkney Shetland (KW 15-99, ZE (All)) and Cornwall (TR 21-25).The special, antimicrobial filter in Chillmax Air is designed to hold water without allowing the bacteria and mould that it contains to develop and grow, it’s even dishwasher-safe so you can regularly clean it and use it time after time. The large capacity water reservoir, combined with the filter, means that Chillmax Air holds a lot of water, so you can rely on Chillmax Air to run for up to ten hours, that’s a whole night’s sleep, or an entire working day in a hot stuffy office, breathing in cool, humid air!
