Only an air-conditioner can offer escape from the heat.
There exist a great variety of air-conditioners - for office, home or car.
They are normally complex and bulky devices.
But today there is also an individual mobile compact air-conditioner that can be installed directly on your desk. We got accustomed to thinking that an air-conditioner is a complex machine that works as an ordinary refrigerator - cools the air inside a room by heating it outside. How can the air-conditioner become small in this case?



Simply by moving the heater to the supersystem!
The main parts of the desk air-conditioner are a removable plastic bottle with ice or cold water and a small fan. The fan forces the room air through the cooling element and directs the grateful cool stream at the user.
The device is so simple that our readers could manufacture it by themselves.

The Korean company ClickNJoy, manufacturer of computer peripherals, made a step forward. The cordless mouse produced by this company does not slip out of the user's hand even when it is very hot. The upper part of the mouse has slots through which the fan installed in its body feeds the cooling air to the palm. The device has several cooling modes and is energized by ordinary batteries.
