Coolzy – The small portable air conditioner

Coolzy is a small portable air-conditioner, or personal air conditioner. Inside you will find the same parts as in a traditional room air-conditioner. Coolzy is just like a tiny refrigerator with a fan that blows cool air at one or more people nearby.

A compressor pushes refrigerant gas into a condenser heat exchanger where a fan blows air through the fins to cool the refrigerant gas so it condenses to a liquid. The liquid, still at high pressure, passes through a thin capillary tube or an expansion valve, reducing the pressure. The low liquid is squirted into a second heat exchanger called the evaporator. Here the liquid evaporates into a cold gas, cooling air flowing past the tubes. The gas, now warmer, passes back to the compressor where it is compressed once again.

Traditional portable air conditioners with two pipes use lots of electricity to pump heat outside, typically 1,200 to 2,400 Watts. Unlike the Peltier coolers, they do pump lots of heat. The CoP is usually between 2.3 and 2.5: these are highly inefficient machines. By contrast, a Coolzy has a CoP of 3! It achieves this by using the very best components available. On top of this, it has one of the best cooling intensities on the market of 3,500 – 4,500 watts per 10 square feet

Portable air-conditioners with only one pipe seem at first to be simpler and more convenient. However, they perform far worse than other room air conditioners because they suck in cooler air from the room to absorb the heat and pump that air outside. Air has to come in from the outside to make up for the air pumped out, bringing heat and humidity with it. Even worse, the hot exhaust pipe radiates heat back into the room. Therefore, the net cooling effect is about one-quarter of a mini-split AC with the same electrical power. Don’t expect more than 3-4 degrees of room cooling.

Unlike other air conditioners, Coolzy does not mix the cool air with the room air. Instead, the cool air is carefully focused at the user’s face and upper body, just where we are most sensitive. Therefore, a very small amount of cooling is much more effective at creating the sensation of comfort. Coolzy sends warm air from the back to the ceiling, just like a kitchen refrigerator or freezer. 

Coolzy is as close as we can get to the ideal mini air-con, a really small portable air conditioner that provides comfort with very little electricity.

So how does this mini AC compare with the myriad of other cooling solutions now available online?

The traditional mini-split AC is great for cooling a crowd. It cools the whole room by thoroughly mixing the cool air. Most of the energy, of course, cools bricks, concrete, steel and timber. However, everyone in the room will experience air with a similar temperature. The air conditioner also removes excess moisture, though this can lead to dryness, skin, nose, throat and eye irritations after many hours. There are three big disadvantages:

  1. A mini-split does not change the air in the room, so air quality decreases as carbon dioxide, volatile organic compounds seeping from furnishings, and body odours all accumulate with time. Opening a door or window provides some fresh air, but significantly increases the power required by the air conditioner for the same cooling.
  2. Because it has to be installed in the wall or ceiling, you need a mini-split in every room where you may need cooling. That’s expensive.
  3. You need to be prepared for large electric bills. Expect to spend much more on electricity than the purchase and installation cost over the lifetime of the air conditioner.

So, if you can afford it, the best combination is to use a Coolzy mini air conditioner and install a mini-split in your entertainment room to cool your crowd of friends when you need to.

When Is a Small Portable Air Conditioner The Best Choice?

A small portable air conditioner is a good choice for people that don’t have a lot of space. This can include people working from home, children’s bedrooms, campers, over landers, people in RV’s or trailer parks.

Be careful because there are many mini portable air conditioners that are scams and don’t work!

Yes, it’s unusual for a brand to be so brazen and call out other products that are ineffective but in this day and age it is far to easy for unscrupulous vendors to advertise on Google, Amazon or eBay and dupe you into purchasing something that is not going to do the job. Below we’ve listed a few of these common scams and explained why you should not purchase them.

Small water coolers that pretend to be mini portable air conditioners

This is a simple machine. A small fan drives air past a wet screen. If the air is dry, evaporating water cools the air. If the air is humid, there is much less cooling. A small water tank provides enough for a couple of hours. Most run with a USB charger and more expensive models come with rechargeable batteries.

In dry air will provide 3 – 5 degrees of apparent cooling if you can place one nearby, 20 – 30 cm away on the desk with the air flow aimed at your face. The cooling effect will be around 50-100 times less than what’s needed to cool even a small room, so don’t expect much.

After several weeks, you will need to replace the wet screen or it will become infested with mould and smelly.

They can be useful inside an air-conditioned building if you find yourself in a localised hot spot, maybe with warm afternoon sun. Wherever you see prices above $25 with slick advertising, know that your hard-earned money will be paying advertisers, not providing you with a valuable product.

Unfortunately, some of the advertisements appear to be internet scams. At our company, we have received calls from customers wanting their money back because they did not receive anything after paying with their credit cards.

Small water cooler, typically 20 cm x 20 cm x 20 cm, often powered by battery or USB cable. These are often claimed to be “mini air conditioners” but their cooling power is very small.

Coolzy provides around 20 times more cooling than these devices.

Very often these scam artists will create a website that looks legitimate but is actually intended to trick you. A classic example is to use a website name that is misspelt or looks similar to a legitimate website. An examples of this is consumereview.com (read that again, see how it’s missing an “r”?). A quick search will reveal more but here are some videos from YouTube to save you the time:

Large water coolers

There are many excellent water coolers that can work well in dry desert climates provided you have a good supply of clean water. They are large machines and need lots of water. The tank has to be refilled every few hours. Most are rather noisy because the fan moves a lot of air past the internal wet screen. Furthermore, you will need to replace the screens regularly to avoid smells as the additional moisture can often lead to fungal growths and mould.

These machines will provide cool air for a large room or even several rooms but they aren’t perfect. For instance:

The Aesthetic – These machines are generally big for two reasons. Firstly, they need to carry a large amount of water. This water runs out quickly nad needs to be replaced often. Secondly, they rely on a high flow rate of air to evaporate the water which means they have huge vents. These vents can be unsightly.

Humidity – The nickname for these air coolers is “swampy” because they increase humidity so much, they make you feel like you’re living in a swamp (Google swamp coolers for more info). The humidity is essential for these machines because that’s their job, they increase moisture in the air so that when it lands on your skin, it theoretically dries and therefore cools you. The drawback is that they don’t work in humid conditions (because it’s already humid so you can’t put more water into the air). Further, if it isn’t already humid, when you use one of these machines, it soon will be. this causes issues like mould, paper curling and stickiness. Not comfortable at all. Even moderate humidity (>35%) greatly reduces the cooling that these machines deliver. Above 50% relative humidity, only slight cooling will be possible.

We can’t be too disparaging because there is a lace for these machines but they certainly aren’t perfect and probably suit a commercial application better than a residential.

I bought the coolzy pro from them to use for my kid. Im in New York so swamp coolers don't tend to work very well. I bought this was because it isn't a swamp cooler. I can report that it worked as advertised and made real cool air out the front. This was great...
