KOMFORT Ultra D105-A
Fig. 1. Unit design and operating logic.
DESIGN
The compact double-skinned unit casing is made of zinc aluminium and has
15 mm thermal and sound insulation of mineral wool.
The mounting angles on the unit casing ensure easy installation. The hinged
side panel of the casing ensures easy access to the internals for service and
maintenance operations.
The spigots for connection to the air ducts are located at the side of the unit
and are equipped with rubber seals for airtight connection to the air ducts.
External rotor motor and centrifugal impeller with forward curved blades are
used for air supply and exhaust.
The motors are equipped with integrated overheating protection with
automatic restart and ball bearings for longer service life. The unit is equipped
with two backdraft dampers, one located in the supply and the other one in
the exhaust air duct.
3-step speed control is performed with the CDP-3/5 external speed switch.
The plate cross-flow aluminium heat exchanger is used for heat recovery in
the unit. The drain pan under the heat exchanger block is used for condensate
collection and drainage.
The heat exchanger is equipped with a freeze protection system.
Two built-in panel filters with filtering class G4 provide efficient supply and
extract air filtration.
OPERATING LOGIC
Clean cold air from outside flows through the air duct to the heat exchanger,
where from it is moved to the room with the supply fan.
Warm stale air is extracted from the room with the exhaust fan and is moved
through the air ducts to the heat exchanger, where is transfers its heat energy
to the intake air. After that it is exhausted outside.
Heat energy of warm and humid extract air is transferred to the cold intake
air. The air flows are fully separated within the heat exchanger.
Heat recovery minimizes heat losses caused by traditional window ventilation
and saves energy.
In summer the heat exchanger performs reverse and transfers cold air from
the cooled extract air for warming up intake air. This contributes to better
performance of the air conditioner in ventilated premises.
The freeze protection thermostat which prevents the heat exchanger icing is
installed in the exhaust air duct. In case of a freezing danger the thermostat
turns the supply fan off to let the heat exchanger get warmed with warm
extract air flow. Turn the thermostat control knob to set a thermostat set
point.
The factory temperature setting is +3 °C.
