Design and function

3.1 Unit description

The ML 263 DC-523 DC room air conditioners
have a REMKO ML...AT outdoor unit as well as an
ML...IT indoor unit.
In cooling mode, the outdoor unit serves to output
the heat extracted by the indoor unit from the room
being cooled. In heating mode, the heat taken up
by the outdoor unit can be discharged by the
indoor unit into the room to be heated. In both
operating modes, the output produced by the com-
pressor precisely matches requirements, and
thereby regulates the nominal temperature with
minimal temperature deviations. This "inverter
technology" results in energy savings over conven-
tional split systems and also reduces noise emis-
sions to a particularly low level. The outdoor unit
can be installed in an outdoor area or, providing
that certain requirements are met, an indoor area.
The indoor unit is designed to be mounted high up
on the wall, in indoor areas. It is operated by an
infrared remote control.
The outdoor unit consists of a cooling cycle with
compressor, fin condenser, condenser fan,
reversing valve and throttle element. The outdoor
unit is controlled by the controller in the indoor unit.
The indoor unit consists of a fin evaporator, evapo-
rator fan, controller and condensate tray.
Floor brackets, wall brackets, refrigerant piping and
condensate pumps are available as accessories.
