How a condenser tumble dryer works
Watch the video it will explain how a condenser tumble dryer works it will show you the air flow through heater and heat exchange condensor plate

- Micro switch
- Condensation water suction pump
There are two air groups inside the condenser tumble dryer:
- •One hot one closed in on itself inside the condenser tumble dryer
- One open cold one, for the circulation of ambient air through the condenser.
The first air group, which is hot and closed in on itself, circulates inside the appliance:
The fan (1) pushes air inside the heat exchanger (5), and from this via the heater unit (2), the air
heats up and via a conveyor enters inside the drum passing through the holes in the back panel.
The warm dry air moves through the laundry moving in the drum removing the dampness and
transforming it into warm damp air; this exits from the front part of the drum through the fluff filter
(3) and the lower filter (4), and is then channelled through the conduit to the fan (1); from here it is
pushed inside the heat exchanger (5) where dampness is condensed. When this comes out, we
have dry air and the cycle continues as described above.
The second air group, the one circulating ambient air through the condenser:
The fan (6) takes in ambient air through an air inlet in the back panel, pushing it into the heat
exchanger (5), and cooling it. The air comes out on the opposite side of the exchanger,
dispersing inside the appliance and coming out of the slots in the kick plate.
The two air groups, the damp hot one and the cold one cross over in the heat exchanger (5),
producing heat exchange and, therefore, condensation of the humidity.
The condensation water that forms inside the exchanger is collected in a trap (7) where there is a
float (9) that informs the circuit board that water is present, so the circuit board powers a pump
(11) which conducts the water from the trap (7) to the tank (8).
The tank was designed to collect the condensation water of a complete cycle with a full load, so
approximately 5.5 litres.
If for any reason the tank is filled beyond its capacity, any overflowing water is collected by the
tank support and channelled along a pipe (not shown in the diagram) back inside the trap (7),
moving the float (9) up, and thus activating the micro switch (10). The electronic control unit
makes 7 attempts to empty the trap in specific amount of time, after which the electronic control
unit recognizes the problem and cuts off the electricity supply to the appliance and lights a LED
to inform the user that the tank is full.
