3.4.0 Operating principle

Turbovex TX Comfort is a decentralized ventilation system with built-in heat recovery for
ventilation of comfort rooms in particular in indoor living spaces.

TX Comfort operates with an aluminium counter flow heat exchanger (5) to ensure
maximum heat recovery. The unit utilizes warm indoor air to heat up inflowing fresh
outdoor air. The counter flow heat exchanger’s sole function is for heat retention.

Airflow:
The air supply ventilator (6) (Figure 2) creates inflow of fresh outdoor air through the filter
(10), leading the inflow through the heat exchanger (5), and further through the air supply
grate (4) and out into the room.

At the same time the air exhaust ventilator (7) creates outflow of indoor air leading it
through the exhaust pipe (2) and further out to the open air outside.

The desired temperature of the air supply is regulated on the control panel. A sensor
records the actual temperature of the flowing air supply. If the temperature is lower than
the setpoint, the control system reduces the flow of the air supply warming it as it flows
through the heat exchanger.

4.2.0 Location

The unit is generally placed on a wall directly under the ceiling. This location best exploits
the coanda effect as it leads the air further into the room along the surface of the ceiling. In
this way inflowing air can mix with the room’s existing air for a longer period of time and
thereby prevent draught. This location, as the point for supply and exhaust airflow,
provides optimal circulation within a room.

Figure 4 Location, conventional

The TX Comfort series also has the possibility of locating the unit in false ceilings. In this
way, the unit is less visible.

The TX Comfort series offer the possibility of installing ducts through the wall or the roof.

Fresh air can also flow in through a wall duct while exhaust air flows out through the roof.
This results in optimal conditions in comparison to a set up with close proximity between
the air supply and the air exhaust.
