Unit functionality
A portable air conditioner works in principle like a refrig-
erator. In a refrigerator, heat is withdrawn from the food
and drinks stored inside it. This heat is expelled to the
surrounding air by means of a heat-exchanger on the
back of the refrigerator.
The portable air conditioner cools the air in the room by
withdrawing heat from it. The heat absorbed is expelled
to the outside and the cooled air is resupplied to the
room where the unit is in operation.
Condensation
During cooling mode, the air that has been sucked in
from the room is cooled until it falls below the dew point
and the steam contained in it condenses on the evapo-
rator surface.
The condensed water drips into the condensation trap
7
attached under the evaporator and, from there, enters
the water tank
8
.
The water tank must be emptied from time to time.

Unit Description
The unit is operated with electric power and has been
designed for universal, fully-automatic, smooth opera-
tion. Its compact design lets it be easily transported and
used almost anywhere.
The device works on the principle of compression. It is
equipped with a closed-loop cooling system, a quiet ra-
dial fan which requires little maintenance and a power
cable with plug.
The fully-automatic control, integrated thermostat,
three-setting fan and water tank with integrated overflow
safety mechanism ensure proper operation of the unit.
This portable air conditioner meets the basic safety and
consumer health requirements outlined in the relevant
EU regulations. It is safe and easy to operate.
How is the air cooled in the room?
In a closed-loop cycle, there is a special medium called
a refrigerant. This refrigerant transports the excess heat
out of the room to be cooled.
At the beginning of the cycle, this refrigerant, in the form
of steam, is sucked in by the compressor
2
, com-
pressed and, as a result, becomes very hot.
The heated refrigerant is routed to an exchanger
mechanism, the condensator
3
. In the condensator, the
refrigerant steam is cooled by the room in the air until it
condenses. The heat is expelled over the flexible ex-
haust hose to the outside by a fan.

, the
pressure on the air is decreased and it is routed to an-
other exchanger mechanism, the evaporator

.
Cold air is actually generated in the evaporator. The liq-
uid refrigerant evaporates, the heat required for this pro-
cess is withdrawn from the air in the room that the fan
6
guides via the evaporator.
The cooled air is resupplied to the room and the cycle
begins again for the refrigerant. The temperature of the
room is gradually lowered through this cyclical process.
Because the cold cycle is a closed-loop, no refrigerant
is lost or consumed.
