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.
How it works
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.
Comparing Coolzy to Portable Air Conditioners
Traditional portable air conditioners with large exhaust pipes use lots of electricity to pump heat outside, typically 1,200 to 2,400 Watts. Learn more about traditional portables and why Coolzy is so much more efficient. 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. Coolzy sends warm air from the back to the ceiling, just like a kitchen refrigerator or freezer.
Small Water Coolers
Powered by battery or USB cable.
Claim to be “mini air conditioners” but their cooling power is very small, typically equivalent to 100 – 200 BTU/hour.
A small fan drives air past a wet screen.
A small water tank provides enough for a couple of hours.
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.
Coolzy provides around 20 times more cooling than these devices.
Large Water Coolers
Unsightly machines and need lots of water.
The tank has to be refilled every few hours.
Rather noisy because the fan moves a lot of air past the internal wet screen.
These machines will provide cool air for a large room or even several rooms.
Even moderate humidity (>35%) greatly reduces the cooling that these machines deliver. Above 50% relative humidity, only slight cooling will be possible.
What makes Coolzy unique
- Instant cooling, no need to wait
- Smaller, lighter and easy to carry
- Apparent noise 44 dB – 54 dB
- Only $43/month electricity cost, other portables cost $150/month or more (12 hours daily use)
- Concentrated cooling (small amount of warm air will be produced from the rear fan)
- Australian invention, patented focusing technology

Note: Split air-conditioners do not provide any fresh air: windows and doors remain closed. Stale room air with odours, methane and carbon dioxide is recirculated all the time.
Traditional portable air-conditioners provide only ~4°C cooling at best
